Description

Technical Field

[0001] The present invention relates to a token, a structure and a method for insertion into a battery pack of a tradesman device. Background Art

[0002] Traditional handheld devices are controlled directly by the user. For example, a drill is controlled by inserting a suitable drill bit and then operating the drill's operating buttons. If a user lacking specialized knowledge uses such a handheld device to perform delicate manual tasks, this can lead to incorrect operation, undesirable results, and potentially compromise operational safety.

[0003] DE10258900A1 discloses a cordless screwdriver for tightening screw components, comprising: a self-powered screwdriver motor disposed on the cordless screwdriver; and at least three measuring devices configured to monitor tightening parameters during the tightening process: a torque sensor for measuring the tightening torque generated by the screwdriver motor; a rotational angle sensor for measuring the current tightening angle from a predetermined measurement position; and a current sensor for measuring the drive current of the screwdriver motor. Furthermore, detection electronics are provided that shut down the screwdriver motor when the tightening torque, tightening angle, and drive current are simultaneously within predetermined rated parameter windows.

[0004] Especially when using handheld devices for difficult or unusual machining tasks, conventional handheld devices have reached their limits. Summary of the Invention

[0005] The object of the present invention is to enable a handheld device to be operated in a simple, safe and fault-tolerant manner.

[0006] This object is achieved by the subject matter having the features of the independent claims. Further embodiments are indicated in the dependent claims.

[0007] According to one embodiment of the present invention, a token for insertion into a battery pack of a craftsman device is proposed, wherein the token has a communication device for providing a communication function when the token is removably inserted into a token receptacle of the battery pack, and a shell for being inserted into the token receptacle in a positive-locking and friction-locking manner, wherein lateral guide rails on mutually opposing longitudinal sides of the shell are designed to be pushed into the battery pack in a guided manner.

[0008] According to another embodiment of the present invention, a structure is provided, which includes a battery pack for a craftsman device and a token with the above-mentioned characteristics, wherein the token is inserted or can be inserted into the token accommodating portion of the battery pack in a removable manner, so that: by insertion, the battery pack and / or the craftsman device can be provided with communication functions by means of the communication device of the token; and a positive locking and friction locking connection can be formed between the battery pack of the token and the housing, in such a way that the lateral guide rails on the longitudinal sides of the housing opposite to each other are guided along the positive locking matching structure in the battery pack.

[0009] According to another embodiment of the present invention, a method is provided, which includes: inserting a token into a token accommodating portion of a battery block of a craftsman device in a removable manner, providing communication functions to the battery block and / or the craftsman device with the help of a communication device of the token by inserting the token into the token accommodating portion of the battery block, and forming a positive locking and friction locking connection between the battery block of the token and the housing by inserting the token into the token accommodating portion of the battery block, whereby the lateral guide rails on the longitudinal sides of the housing opposite to each other are guided along the positive locking matching structure in the battery block.

[0010] In the context of this application, a "token" is understood to mean, in particular, an identification mark that establishes a functional connection between the token and a battery pack and / or a craftsman device. This identification mark can be used in a connected system, which can include the token, the craftsman device mechanically coupled to the token, and optionally one or more other devices or nodes. In particular, the token can be a hardware component that provides communication functionality. The token can also be used to identify and / or authenticate the user to whom the token can be assigned. The token can be an electronic token, for example, providing corresponding control, monitoring, and / or communication functions associated with a processor.

[0011] In the context of this application, a "battery block" is understood to mean, in particular, an electrical energy supply device that can supply electrical energy to a tradesman's device (e.g., an electric handheld device such as an electric drill) connected to the battery block and / or a token connected to the battery block. For this purpose, the battery block can include one or more battery cells. Preferably, the battery block is rechargeable, i.e., after being discharged, it can be recharged by connecting to a power source, for example.

[0012] In the context of this application, a "trader device" is understood to mean, in particular, a device used by a tradesman or other user during manual labor. This may include, in particular, a powered handheld device (e.g., a cordless screwdriver), a tool (e.g., a hammer, pliers, a file, a screwdriver, or a drill bit), a tool kit containing multiple tools or tool elements (e.g., a drill bit box with drill bits or a drill bit box with drill bits), a storage system (e.g., a tool box), consumables (e.g., bolt anchors or a screw box with screws), and / or a vehicle (e.g., a motor vehicle, forklift, or tool cart that allows a tradesman to transport their device to the work site), and / or other tradesman equipment (e.g., a ladder). A tradesman device may also be a battery pack or an adapter between a battery pack and a machining device (e.g., a drilling module of a drilling rig). For example, a token can be inserted into such a battery pack or adapter.

[0013] In the context of this application, a "handheld device" is understood to mean, in particular, a portable device that can be manually operated and carried by a user and that can be used to perform craftsman tasks, such as machining substrates. Advantageously, the handheld device can be an electric handheld device that operates with an electrically generated drive force. Such an electric handheld device can be controlled by an electrical control signal, which can be provided directly or indirectly, in particular, via a token. In particular, the handheld device can be used to drill holes in substrates by applying a drive force in the form of a longitudinal force and / or torque, and / or to apply a drive force in the form of a longitudinal force and / or torque to a fixing element to be inserted into a substrate. For example, the handheld device can be designed to rotate a machining device, thereby rotating a drill bit and / or a fixing element. Examples of electric or motor-driven handheld devices include cordless screwdrivers, cordless drills, rotary screwdrivers, pulse screwdrivers, ratchet screwdrivers, drills, impact screwdrivers (in particular cordless impact screwdrivers), and hammer drills.

[0014] In the context of this application, a "communication device" may be understood specifically as a device of a token that enables communication, particularly wireless communication, between the token and a communication partner device. A communication partner device may, for example, be a battery pack coupled to the token, a craftsman device coupled to the token directly or via a battery pack, or another device communicatively coupled (e.g., via a communication network) (e.g., a user terminal device with an installed application). Such a communication device may, for example, include at least one communication antenna (particularly a transmitting and / or receiving antenna) and associated corresponding processor resources of a processor, which may, for example, enable wireless communication with one or more other nodes of the communication network according to the communication protocol of the communication network. Alternatively, the communication functionality may be provided by the token independently of the communication network, through direct communication with the communication partner device. In this manner, in addition to controlling the craftsman device mechanically coupled to the token, the token may also engage in unidirectional or bidirectional communication with one or more other nodes, such as downloading and / or uploading information. For example, downloading information from a communicatively coupled node to the token may include downloading a process control plan for a processing task that a user is to perform using the craftsman device mechanically coupled to the token. For example, uploading information from a token to a communicatively connected node may include uploading tracking data that allows tracking the operation of the token and / or a handheld device connected thereto for documentation and / or quality monitoring. Operational data recording the completion of a processing task by a craftsman's device connected to the token may also be uploaded from the token to the communicatively connected node. Uploading or downloading can provide corresponding communication functions. In particular, the communication device can be designed as a single connection function module. However, the functions of the communication device (in particular, providing wireless connection or communication) can also be implemented by multiple cooperating components. For example, one or more circuits can be used to combine discrete components such as a microcontroller, a radio transmitter and an antenna to form a communication device.

[0015] In the context of this application, a "token receptacle" is understood to mean, in particular, a defined receptacle space within a battery pack, the shape and dimensions of which are designed to accommodate a corresponding token and to functionally cooperate with the received token. On the one hand, the shape and dimensions of the token receptacle enable it to accommodate the token with a positive and frictional fit. Furthermore, the functional configuration of the token receptacle enables the token to be received in a defined manner in the token receptacle, thereby enabling a problem-free electrical connection, data exchange connection, and / or power supply connection between the token and the battery pack.

[0016] In the context of this application, a "housing" is understood to mean, in particular, a component that at least partially defines the outer contour of the token. The housing can be designed as a single piece or as a multi-part component, such as a base and a cover. The housing can accommodate the communication device (and optionally other components) within it and protect it mechanically and / or electrically from environmental influences. The housing can be designed to provide external access to the electrical contacts of the token.

[0017] In the context of this application, "positive-locking and friction-locking insertion" is understood to mean, in particular, inserting the token into the token receptacle in such a way that a positive-locking and friction-locking connection is easily established between the token and the battery block, thereby holding the token in a defined position and orientation and securely and securely fixed within the token receptacle on the battery block. Furthermore, the token and battery block can be designed so that, through positive-locking and friction-locking insertion, the token is not only mechanically secured to the battery block in a defined manner, but also simultaneously establishes an electrically conductive, energy supply, and / or data transmission connection between the token and the battery block. The positive-locking connection between the housing and the token receptacle can be achieved by corresponding structural shapes that prevent relative movement of the housing and the battery block, except in the direction of insertion or removal. In particular, the positive-locking connection can be achieved by nesting (optionally with an undercut) between the housing and the token receptacle of the battery block. By applying a normal force or at least a normal force component on the surfaces of the housing and the token receptacle of the battery block to be connected, an additional frictional connection between the housing and the token receptacle can be generated, thereby preventing a mutual displacement of the housing and the token receptacle.

[0018] In the context of the present application, "lateral guides on mutually opposing longitudinal sides of the housing" are understood to mean, in particular, elongated, at least partially linear, mechanical structures on the housing that cooperate with corresponding mechanical counterstructures on the battery block token receptacle to mechanically insert and remove the token into and from the token receptacle only along a predetermined guide direction, otherwise mechanical insertion and removal is impossible. The guides are preferably formed on two opposing side faces of the token that are oriented vertically during insertion. Alternatively or additionally, the guides may also be formed on two opposing main faces of the token that are oriented horizontally during insertion. The vertical end faces of the housing may be free of guides. Thus, lateral guides are understood to be formed on the outer faces of the housing, but not on its outer and inner end faces in the assembled state. In particular, the guides may be formed by groove-like depressions and / or elongated projections on the (preferably flat) outer face of the housing.

[0019] According to one embodiment of the present invention, a token is provided that can be reversibly inserted into a corresponding token receptacle of a battery pack. Advantageously, simply inserting the token provides communication functionality to the battery pack or a tradesman's device operatively connected thereto via the token's communication device. This communication functionality can be deactivated by removing the token. Simultaneously, simply inserting the token establishes a secure positive-locking and friction-locking connection between the battery pack and the token housing. This connection can be released by removing the token. To this end, lateral guides can advantageously be guided along mating positive-locking structures in the battery pack on opposing longitudinal sides of the housing. This configuration enables a reliable connection between the token and the battery pack in a user-friendly and error-proof manner. The strength provided by the positive-locking and friction-locking connection ensures that the connection between the token and the battery pack remains secure even when the tradesman's device (e.g., a hammer drill) connected to the battery pack is exposed to harsh operating conditions.

[0020] In the following, further exemplary embodiments of tokens, structures, and methods are described.

[0021] According to one exemplary embodiment, the lateral guides can be formed by inwardly recessed guide grooves in the opposing longitudinal sides of the housing. A guide groove can be understood as an elongated, groove-like recess. If the guides are formed by guide grooves, vulnerable protrusions, such as latches, can be avoided. This avoids noticeable protrusions that could damage the token if the user handles it outside the battery pack.

[0022] According to one exemplary embodiment, the lateral guide rails on at least one of the mutually opposing longitudinal sides of the housing may include at least one latching element for forming a latching connection between the token and the battery pack. In this manner, when the token reaches a predetermined target position in the token receptacle, a latching connection between the token and the battery pack is achieved. For example, the at least one latching element on the side of the token may include a protruding latching nose, which may, for example, engage with a corresponding latching recess in the token receptacle (or vice versa).

[0023] According to one exemplary embodiment, the lateral guides on at least one mutually opposing longitudinal side of the housing body may include at least one centering aid for centering the token in the battery pack. This centering aid can be formed, for example, by mechanical structures on the side of the token and ensures correct positioning of the token relative to the battery pack. In this way, the centering aid can also facilitate reliable and unambiguous establishment of an electrical and / or energy connection by mechanically inserting the token into the token receptacle.

[0024] According to one exemplary embodiment, the housing body may include a removal aid on an externally accessible end face of the token when inserted into the battery pack, for removing the token from the battery pack. This removal aid may, in particular, be a pull-out removal cord or filament, more precisely, a removal cord at least partially disposed in a removal groove on the end face. The positive and frictional connection between the token and the battery pack ensures secure retention of the token in the battery pack, which is particularly advantageous when operating corresponding craftsman equipment under harsh operating conditions. On the other hand, the high connection force between the token and the token receptacle may make it difficult for the user to remove the token from the receptacle. This problem is exacerbated by the fact that tokens are conveniently small in size. Therefore, it is particularly advantageous to attach the removal aid to the external end face of the token, which remains accessible to the user after insertion. This allows the user to easily remove the token from the receptacle by simply applying a pulling force. This removal aid can be particularly advantageously implemented using a removal cord, for example, by designing it as a removal cord connected to both ends of the end face. In particular, the removal cord can be designed as a U-shaped loop with both ends fixed to the end surface, allowing the user to grasp and pull it between the connection points. If necessary, the U-shaped loop also allows the marker to be pried out using a screwdriver or other slender tool. If the removal cord is positioned in a removal recess in the housing, the user can operate the removal cord particularly easily and conveniently.

[0025] According to one exemplary embodiment, the housing can be provided with electrical contacts on, and in particular, only on, an end side that is inaccessible from the outside when the token is inserted into the battery pack. These contacts are used to establish an electrical connection between the token and the battery pack. Thus, the electrical contacts can be provided on the end face of the token inserted into the battery pack and connect to mating contacts on the battery pack by forming a plug connection between the token and the battery pack. Positioning the electrical contacts within the battery pack effectively protects the user from the conductive contacts. Simultaneously, the contacts are protected from the outside, such as from environmental influences such as moisture.

[0026] According to one exemplary embodiment, a token may include electrical contacts for establishing an electrical connection between the token and a battery pack, wherein the electrical contacts are protected from external moisture by a moisture barrier. During operation of the token, the token may be exposed to conductive and / or corrosive media (e.g., ambient humidity). This could damage the contacts or lead to hazardous operating conditions. By not exposing the electrical contacts directly, but rather protecting them from moisture by the moisture barrier while still maintaining accessibility for establishing an electrical connection, the token's service life and operational reliability can be extended. The moisture barrier can ensure a media-tight connection while still enabling a reliable electrically conductive connection with a mating contact. For example, the moisture barrier can be designed as a plug sealed by an electrically insulating lip (e.g., an elastomeric lip) or as a waterproof contact (e.g., formed by a hydrophobic drainage element).

[0027] According to one exemplary embodiment, the housing may include an internally connected stop on an end side accessible from the outside when the token is inserted into the battery pack, which limits the insertion depth of the token into the token receptacle of the battery pack. This stop may, for example, be designed as a mechanical protrusion on the token that strikes a corresponding limiting structure of the battery pack when the maximum depth or target position is reached. In this way, the token can be prevented from being inserted too deeply into the battery pack, thereby protecting it from damage and ensuring that it can be removed.

[0028] According to one exemplary embodiment, the housing may include an inclined insertion surface adjacent to an end face of the token that is inaccessible from the outside when the token is inserted into the battery pack. Thus, a structure may be formed on the inner end face of the inserted token, which facilitates the token's entry into a lateral target position or orientation and cooperates with a mating structure of the battery pack for this purpose. This further improves the token's fault tolerance during operation.

[0029] According to one exemplary embodiment, a communication antenna of the communication device can be arranged adjacent to an end face that is accessible from the outside when the token is inserted into the battery pack. This communication antenna can be designed as a transmitting and / or receiving antenna and can transmit and / or receive electromagnetic radiation (particularly high-frequency radiation) during operation. To be able to perform this task in a particularly fault-tolerant manner, it can be advantageous if, when the token is mounted on the battery pack, at least one communication antenna is arranged on the outside. This protects the at least one communication antenna from undesirable shielding of the electromagnetic communication radiation.

[0030] According to one exemplary embodiment, when the token is inserted into the battery pack, the communication antenna can be positioned within the outer 20% of the length of the token housing, or within the outer 2 cm. Here, the housing length refers to the length of the token along the insertion direction of the token into the token receptacle of the battery pack. For example, the length of the token can range from 1 cm to 10 cm, preferably from 2 cm to 6 cm. To ensure low-interference, high-performance wireless connectivity with a communication partner, the communication antenna is preferably positioned within the outer 20% of the length of the token, or within the outer 2 cm.

[0031] According to one exemplary embodiment, the communication antenna of the communication device, on the one hand, and the electrical contacts for establishing an electrical connection between the token and the battery pack, on the other hand, can be arranged in longitudinally opposing halves of the housing. In this way, the transmission of electromagnetic waves involving the communication antenna can be spatially separated from the transmission of wired electrical signals or power, thereby suppressing unwanted interactions.

[0032] According to one exemplary embodiment, the housing can be designed to be approximately cuboid. The direction of maximum extension of the token can coincide with the insertion direction. The guide rails are preferably formed on the two smallest opposing surfaces of the approximately cuboid token. Those skilled in the art will appreciate that the housing's shape can be accurately described as "approximately cuboid" because the functional structures (particularly the guide grooves, removal recesses, latching elements, etc.) can be provided on the main surfaces of the housing.

[0033] According to one exemplary embodiment, a token can be configured to communicate with at least one communicatively connectable node of a communication network or another communication partner device via a communication device. This node or other communication partner device can be selected from the following group: another token, a portable user terminal device storing an application (configurable for communicating with the token), a central control device (e.g., for centrally managing or controlling handheld craftsman devices), and a replenishment ordering device for reordering consumables required to operate the craftsman devices. According to one embodiment, multiple tokens can communicate with each other.

[0034] According to one exemplary embodiment, the token may include at least one sensor, in particular selected from the group consisting of: a user identification sensor, a gyroscope sensor, a positioning sensor, a temperature sensor, a sound pressure sensor, a vibration sensor, an acceleration sensor, a position sensor, a current sensor, a voltage sensor, and sensors for measuring electric and / or magnetic fields. The token may particularly advantageously be equipped with a user identification sensor, such as a fingerprint sensor or a facial recognition sensor. When designed for a fingerprint sensor, the user simply places their finger on the token for identification. After a mechanical connection is established between the token and the Craftsman device, the user's identity, as detected by the sensor, can be used to determine whether the user is permitted or authorized to operate the Craftsman device and, if so, whether their use of the Craftsman device is subject to certain restrictions or specific functional limitations. These user-specific adjustments to the operation of the Craftsman device can advantageously be based on a user profile of the user identified by the sensor. This authorization profile can, for example, be stored in the token or retrieved from the token via a communication network. Alternatively or in addition, the token may also include a gyroscope sensor. This gyroscope sensor can be an acceleration sensor that reacts to acceleration, rotational motion, or changes in position. This information can be used, for example, to control the Craftsman device. For example, if a craftsman device is dropped along with a token, a gyroscopic sensor can detect the impact and shut down the craftsman device. Alternatively or in addition, at least one of the token's sensors can include a location sensor, such as a GPS sensor. This allows the token to determine the current location of the token and its mechanically coupled craftsman device. For example, the operation of the craftsman device can be restricted to a specific location or area (e.g., a specific construction site). If the location sensor detects that the token and craftsman device are outside of an authorized area, the token can control the craftsman device to prevent operation in unauthorized areas, thereby improving safety. This improves the protection of the craftsman device from misuse. A temperature sensor can also be integrated into the token. For example, if the detected temperature exceeds the permitted operating range of the craftsman device, control technology can prevent the use of the handheld device coupled to the token. For example, if a chemical anchor is to be installed using the craftsman device, but the ambient temperature exceeds the permitted temperature range for chemical anchor installation, installation can be prevented.

[0035] According to one exemplary embodiment, the token can include at least one communication antenna, in particular selected from the group consisting of a GPS antenna, a BLE antenna, an ultra-wideband antenna, a Bluetooth antenna, a Wi-Fi antenna, and a narrowband IoT antenna. According to one exemplary embodiment, the token can include at least one communication antenna, in particular selected from the group consisting of a GPS (Global Positioning System) antenna, a BLE (Bluetooth Low Energy) antenna, an ultra-wideband (UWB) antenna, a Bluetooth antenna, a WLAN (Wireless Local Area Network) antenna, and a narrowband IoT (IoT) antenna. Such a communication antenna enables wireless communication with the token via a corresponding communication protocol, thereby enabling more refined control of a craftsman device mechanically coupled to the token using data transmitted according to the communication protocol.

[0036] According to an exemplary embodiment, the token may have at least one processor, in particular selected from the group consisting of a Bluetooth processor, a narrowband Internet of Things (IoT) processor, an LTE (Long Term Evolution) processor, a 5G processor, and an NFC (Near Field Communication) processor. Alternatively or in addition, the processor may be operated according to other existing or future communication protocols.

[0037] According to an exemplary embodiment, the arrangement can include a Craftsman device (particularly designed for an electric handheld device) that is connected or connectable to a battery pack in order to supply the Craftsman device with electrical energy during operation via the battery pack and / or to provide the Craftsman device with communication functionality during operation via a communication device of a token. It is particularly advantageous if a token receptacle is provided in the battery pack and the battery pack is electromechanically coupled to the Craftsman device. In this way, existing Craftsman devices can also be retrofitted with communication functionality by simply combining the Craftsman device with a battery pack having a token receptacle for accommodating a token with a communication device. Advantageously, this eliminates the need for a complete redesign or reconfiguration of the Craftsman device.

[0038] According to one exemplary embodiment, a battery pack may include an electronic circuit board with a recess. A token may be accommodated in the recess, allowing the electronic circuit board, as a mating structure, to engage with guide rails on opposing longitudinal sides of the housing in a form-fitting and frictional manner. For example, the edges of the electronic circuit board may engage with guide grooves in the housing, thereby defining the recess. For example, the electronic circuit board may be a printed circuit board, on which one or more electronic components may be mounted. These electronic components may include, for example, a processor chip, a communication chip, a memory chip, and / or passive components. The functions of these chips may also be integrated into a common chip, thereby enabling a particularly space-saving design of the token. The electronic circuit board may be provided as a rigid board, into which a recess may be formed using simple means (e.g., by milling). The recess may be configured to accommodate the token. Furthermore, the rigid board is well suited for engaging with the guide rails of the token at the edge of the recess in a form-fitting and frictional manner. By combining a token with lateral guide rails, particularly designed as guide grooves, with the electronic circuit board carrying the communication device, a particularly advantageous and compact design of the token is achieved.

[0039] According to one exemplary embodiment, the structure can include a functional device (e.g., a tool box) with a token receptacle, wherein the token can be removably inserted or inserted into the token receptacle of the functional device, rather than into the token receptacle of the battery pack. Thus, the token can be designed to be universal and can be selectively combined with different battery packs, tradesman equipment, or functional devices to provide them with communication functionality.

[0040] According to one exemplary embodiment, the token holder of the battery pack is accessible to the user from the outside. When the battery pack or a connected craftsman device is used as intended, the user can simply insert the token into the token holder with a single hand, thereby equipping or retrofitting the entire system with communication functionality. For this purpose, the token holder can be designed as a permanently open slot, freely accessible from the outside, or it can be easily covered, for example, by a removable, foldable, or twistable protective cover.

[0041] According to an exemplary embodiment, the token receiving portion of the battery block may be designed as a receiving slot into which the user can reversibly insert the token in an intuitive and guided manner.

[0042] According to one exemplary embodiment, the token and battery pack can be designed so that when the token is inserted into the token receptacle of the battery pack, the battery pack provides electrical energy to the token. Thus, the token's power supply can be provided by the guided insertion of the token into the receptacle using a positive and frictional fit. This allows the token to be designed without its own power supply, making it simpler and more compact. The battery pack can also be used to power the token, while also providing the token's communication functionality. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Before describing exemplary embodiments of the present invention with reference to the accompanying drawings, some general aspects of exemplary embodiments of the present invention will first be explained.

[0052] According to an exemplary embodiment of the present invention, a token is provided for easily, temporarily or permanently inserting the token into a battery pack of a tradesman device (e.g., an electric drill). The token advantageously has a communication device for providing a preferably wireless communication function. By removably inserting the token into the token receptacle of the battery pack, the battery pack or tradesman device can be enabled for wireless communication. The housing of the token forms a positive and frictional connection with the token receptacle of the battery pack. Particularly advantageously, at least two lateral guides on mutually opposing longitudinal sides of the housing allow the token to be inserted into the battery pack in a guided, thus error-tolerant, and user-friendly manner. In this way, existing tradesman devices can be equipped or retrofitted with communication functionality by simply connecting the battery pack of the tradesman device for power supply to the plug-in token.

[0053] The token can be optionally mounted in a battery module or on a tracker housing, which can in turn be mounted on any tradesman's device or functional device (e.g., a tool box). This provides a flexible modular system with tokens that are compatible with a wide range of devices.

[0054] Advantageously, a female or concave plug element can be provided on the token. Since protruding latches or the like can be avoided in this design, the token can be protected from mechanical damage during external handling.

[0055] According to a preferred embodiment, the token can be designed to form a media-tight (particularly liquid-tight) connection with the battery module or tracker housing. This can be achieved, for example, by using a contact element protected by an elastomeric lip. Alternatively or in addition, a waterproof contact element can also be provided, which can, for example, contain a hydrophobic, water-repellent medium.

[0056] The token's one or more transmitting and / or receiving antennas (also referred to as at least one communication antenna) can also be positioned so that, when the token is inserted into the battery module, the at least one antenna is positioned on the outside (particularly within the outer 20% of the token's length and / or within the outer 2 cm). This can further improve the token's signal exchange within its communication functionality. Preferably, if the electrical contacts are arranged to the left of center, such an antenna of the token can be arranged on the opposite contact side, particularly longitudinally to the right of the token's center (and vice versa).

[0057] The outer contour of the token can be connected to the receiving cavity of the battery module in a positive-locking manner. This allows for a secure electrical contact connection while mechanically securing it in place.

[0058] The token can advantageously be provided with a snap-in nose in order to form a snap-in friction fit when inserted into the battery module.

[0059] Furthermore, the token can be designed with a handle element which can still be gripped from the outside after insertion into the battery module, so that the token can be removed from the battery module with a single-handed operation.

[0060] The guide grooves on the sides of the token can engage with corresponding rails of the battery module, which can be formed particularly advantageously by the circuit board of the battery pack. In this way, a pull-out guide can be formed in the simplest way, but it takes into account the specific requirements of the token in a special way, as described here.

[0061] Figure 1 The structure of a craftsman device 102 and a token 100 according to an exemplary embodiment of the present invention is shown, and the craftsman device and the token are connected in a communication network 120.

[0062] In short, each token 100 is intended to be inserted into a corresponding battery pack 142 of a selected craftsman device 102. In this case, each token 100 can be selectively inserted into each battery pack 142. Each token 100 comprises a communication device 118, which is used to provide wireless communication functionality to the selected battery pack 142 or the craftsman device 102 selectively coupled thereto, when the user removably inserts the token 100 into the token receiving portion 152 of the selected battery pack 142. In addition, the token 100 has an outer housing 101, for example made of plastic, in which the various components of the token 100 are arranged. The housing 101 is designed to be inserted into the token receiving portion 152 in a form-fitting and friction-fitting manner. For Figure 1The token 100 shown in detail in FIG. has four longitudinal sides, i.e., sides extending perpendicular to the paper plane. Lateral guides 105 (formed by guide grooves 107 in the illustrated embodiment) of the housing 101 act on at least two of the four longitudinal sides of the housing 101, ensuring guided insertion into the battery pack 142. Inserting the token 100 into the corresponding token receptacle 152 of a selected battery pack 142 (which in turn is connected to a selected craftsman device 102) results in a structure consisting of the token 100, the battery pack 142, and the craftsman device 102. The battery pack 142 provides energy to both the craftsman device 102 and the token 100. The token 100, via its communication device 108, provides wireless communication functionality to the battery pack 142 and / or the craftsman device 102. The craftsman device 102 is, in turn, configured to perform a functional task, such as drilling a hole in a wall if the craftsman device 102 is designed as an electric drill. Advantageously, the token 100 can be simply inserted into the token receiving portion 152 to provide the battery pack 142 and / or the craftsman device 102 with wireless communication functionality via the communication device 118 of the token 100. This allows the craftsman device 102, even if it does not itself have wireless communication functionality, to be easily equipped or retrofitted with such functionality. Simultaneously, a reversible but reliable, positive-locking and friction-locking connection can be established between the battery pack 142 and the housing 101 of the token 100 simply by insertion, in that the lateral guides 105 on the mutually opposing longitudinal sides of the housing 101 are aligned along the positive-locking mating structures ( Figure 1 Not shown, see Figure 2 127 in the figure). Thus, by inserting the battery pack 142 onto the craftsman device 102 in a form-fitting and friction-locking manner, an electromechanical connection for energy and / or data transmission can be established between the battery pack 142 and the craftsman device 102, thereby electrically conductively connecting the electrical contacts 141, 143 of the battery pack 142 and the craftsman device 102 to one another. The energy and / or data transmission connection between the token 100 and the battery pack 142 can be disconnected again by simply removing the token 100.

[0063] Figure 1 The principles of the structure shown in are described in more detail below:

[0064] The illustrated arrangement has a plurality of tokens 100 which, for example, can be shaped and dimensioned in the same manner. Figure 1 Only two such tokens 100 are shown in FIG. 1 (one shown in detail and the other shown schematically), but a larger number of tokens 100 (eg at least ten, in particular at least one hundred) may be contained in a structure.

[0065] Furthermore, a plurality of craftsman devices 102 are provided in the structure. Figure 1Only two such artisan devices 102 are shown, but a larger number of artisan devices 102 (for example, at least ten, in particular at least one hundred) can be accommodated in one structure. Some or all of the artisan devices 102 can be connected to a battery pack 142. Such a battery pack 142 can have a mechanical token receptacle 152 of a defined shape and size, here designed as an insertion opening or receiving opening, for mechanically connecting to a corresponding mechanical connection device 110 of any token 100 selected by the user. The mechanical connection device 110 is arranged on the outside of the housing 101 of the corresponding token 100. A positive-locking and friction-locking connection can be formed between each mechanical connection device 110 of each token 100 and each mechanical token receptacle 152 of each battery pack 142 by plugging, for example by means of cooperating guide rails.

[0066] When a mechanical connection is established between the token 100 and the selected battery pack 142 by inserting the mechanical coupling device 110 of the token 100 into the token receptacle 152 of the selected battery pack 142, an effective or communication connection is simultaneously established between the token 100, the battery pack 142, and / or the connected craftsman device 102. More specifically, in the illustrated embodiment, an electrical connection is established between one or more electrical contacts 156 on the outside of each token 100 and one or more electrical mating contacts 136 on the inside of each token receptacle 152 of each battery pack 142. Thus, the positive-locking and friction-locking connection formed between the respective token 100 and the corresponding token receptacle 152 of the battery pack 142 forms an electrical contact and, therefore, an electrically conductive connection. This electrical connection also establishes an electrical communication connection between the token 100 and the battery pack 142, which can, in particular, transmit electrical signals (e.g., control signals). As an alternative to such a contact-based electrical connection, a wireless or contactless communication connection can be established between the token 100 and the battery pack 142 connected thereto or the craftsman device 102 connected thereto, by inserting the token 100 into the token receptacle 152 and placing the transponder of the token 100 (e.g., an RFID tag, not shown) within a readable distance (not shown) of a transponder reader device (e.g., an RFID reader device, not shown) of the battery pack 142.

[0067] Advantageously, if the token 100 is inserted into the token receiving portion 152 of the battery pack 142, the token can establish communication with the battery pack 142 and / or the craftsman device 102, i.e., can be used to control the battery pack 142 and / or the craftsman device 102. Alternatively or additionally, such a token 100 can also only provide a communication function for the battery pack 142 connected thereto.

[0068] By selectively coupling each token 100 with each mechanical token receptacle 152 of a selected battery block 142 , a flexible modular system is created for communicating, operating, controlling, and / or managing craftsman devices 102 in complex environments.

[0069] exist Figure 1 In the figure, the craftsman device 102 is only partially and schematically shown. For example, the craftsman device 102 can be designed as an electric or motorized handheld device, such as an electric drill, an electric cordless screwdriver, or the like. A craftsman device 102 designed as an electric or motorized handheld device can, for example, include a functional device 134 that performs the actual function of the respective handheld device and can be driven by an electric or motorized drive. In a craftsman device 102 designed as a drill, the functional device 134 can, for example, be a drill chuck (particularly one with a drill bit). In a craftsman device 102 designed as a cordless screwdriver, the functional device 134 can, for example, be a drill bit holder (particularly one with a bit). Furthermore, the handheld device can be connected to a battery pack 142, such as a removable and rechargeable battery pack. Such a battery pack 142 can provide electrical drive energy for the functional device 134 during operation. Furthermore, when a token is accommodated in the token receptacle 152 of the battery pack 142, the battery pack 142 can also power the respective token 100. The handheld device may also have a control device 137 and / or the battery pack 142 may have a control device 138 , which may be designed to control the handheld device or the battery pack 142 and / or cooperate with the processor 106 of the connected token 100 .

[0070] Some or all of the above-mentioned craftsman devices 102 may be temporarily or permanently equipped with a token 100 that is inserted into a corresponding battery pack 142 .

[0071] The artisan device 102 is advantageously designed to be coupled to the token 100 via a corresponding battery module 142, so that a user can be authorized, configured, and / or prohibited from using the artisan device 102 coupled to the token 100 based on a personal authorization profile. More specifically, a user of the token 100 can be assigned a personal authorization profile, which may include information regarding the user's capabilities and authorizations for using certain artisan devices 102, but may also define usage restrictions and / or prohibitions for certain artisan devices 102. This personal authorization profile may be stored in the memory device 128 of the token 100, in the memory device 140 of the battery module 142, in the memory device 139 of the artisan device 102, and / or in a database 132 of a node (in the illustrated embodiment, the central control device 124 or another node) communicatively coupled to the token 100 via the communication network 120.

[0072] The structure of the token 100 is described in more detail below. Figure 1 As shown in detail. The token 100 is used, for example, for user-related control of an optional artisan device 102 in the structure and has a processor 106 for this purpose. For example, the processor 106 can be embedded in the interior of the token 100 and thus protected. The processor 106 can be designed, for example, as a microprocessor. The processor 106 can be designed as part of a processor unit, as a whole processor unit or as a plurality of cooperating processor units. The processor 106 of the token 100 is used for control technology coordination with the individual artisan devices 102 in the structure and, in particular, for functional coordination with the selected artisan device 102 and / or the corresponding battery pack 142, into which the token 100 is introduced.

[0073] Furthermore, the token 100 comprises an optional encryption unit 108 for supporting encrypted communication of the token 100. More precisely, the encryption unit 108 can be used to encrypt the communication between the token 100 and a communication partner device in the communication network 120.

[0074] As already mentioned, the token 100 has a mechanical coupling device 110, which is designed for a preferably positive-locking mechanical coupling with the token receptacle 152 of the battery pack 142. The mechanical coupling device 110 of the token 100 is defined by its outer shape, which is shaped inversely to the inner shape of the token receptacle 152 of the corresponding battery pack 142.

[0075] The token 100 can advantageously be designed to control the operation of the battery pack 142 and / or the connected craftsman device 102 via the processor 106 (and optionally the encryption unit 108, using encrypted communication) when the connection device 110 is mechanically connected to the token receptacle 152 of the selected battery pack 142. More specifically, the token 100's processor 106 can control the craftsman device 102, particularly its functional device 134, so that the craftsman device 102 performs a desired machining task in a defined manner. For example, the token 100's processor 106 can specify the torque that a drill bit of the craftsman device 102, designed as a drilling machine, should apply to the substrate to be drilled. Alternatively or additionally, the token 100 can also control the craftsman device 102 via its processor 137 and / or the processor 138 of the battery pack 142. The token 100 can also provide communication functionality with the battery pack 142 and / or the craftsman device 102 via its communication device 118.

[0076] Advantageously, token 100 can be designed for user-related control of craftsman device 102, particularly based on the user's personal authorization profile. For this purpose, token 100 can be equipped with an identification device 170 for identifying the user of token 100. Identification device 170 comprises a sensor 112 (e.g., designed as a fingerprint sensor) and a portion of processor 106 that identifies the user based on sensor data determined by sensor 112 (e.g., by comparing patterns with reference data). More specifically, sensor 112 can be designed, for example, as a fingerprint sensor, which the user places their finger on for identification.

[0077] For example, the aforementioned storage device 128 of the token 100 may store personal authorization files indicating a user's authorization to the craftsman device 102 or information granting the user access rights. However, the authorization files of one or more users may also be stored in an entity remote from the token 100, such as in a central database 132 of the central control device 124, with which the token 100 can be communicatively connected via the communication network 120.

[0078] During operation, when the token 100 is housed in the token receiver 152, the token 100 can be powered by the battery pack 142 of the craftsman device 102. In this way, the token 100 can be independent of its own power supply device. Alternatively, the token 100 can be equipped with its own power supply device, such as a button battery.

[0079] Figure 1 It is also shown that the token 100 can have a communication antenna 114, such as a Bluetooth antenna or a WLAN antenna. For reasons of versatility, it is also possible for the token 100 to have multiple communication antennas 114, which, for example, support different communication protocols. For example, the communication antenna 114 can be implemented in the form of a planar coil, preferably arranged within the surface area of ​​the token 100. The communication antenna 114 can be designed as a transmit / receive antenna, i.e., have both transmit and receive functions. It is also possible to provide a transmit antenna and a separate receive antenna, or to provide only one communication antenna.

[0080] In particular, Figure 1 The token 100 shown in FIG has the aforementioned communication device 118, which may be formed by the communication antenna 114 in cooperation with the corresponding part of the processor 106 and optionally with the encryption unit 108. The communication device 118 is used to communicate the token 100 with one or more communication nodes via a communication network 120. The communication network may be, for example, the public Internet, an intranet, or a mobile network.

[0081] For example, a token 100 can communicate with another token 100 in the structure via the communication network 120 or directly. Alternatively, or in addition, a communication link can be established between the token 100 and an application or other software stored on a portable user terminal 122 via the communication network 120. In the illustrated embodiment, the user terminal 122 is a mobile radio device having a user interface, through which a user can control and / or monitor the communicatively coupled token 100 and / or the craftsman device 102 coupled to the token via the battery pack 142. The user can also control and / or monitor the structure from a remote location via the user terminal 122. For example, the token 100 can connect to the mobile radio user terminal 122 via an application. Data can be downloaded to the token 100 via the user terminal 122, such as user files of the user of the user terminal 122. Furthermore, during operation, the token 100 can access resources of the user terminal 122, such as the processor contained therein and / or the camera of the user terminal 122.

[0082] Alternatively or additionally, a communicative connection can be established between the token 100 and a central control device 124 (e.g., for controlling a plurality of craftsman devices 102) via the communication network 120. The central control device 124 can be provided with access rights to a database 132, from which data sets can be transmitted to the token 100. These data sets can include, for example, authorization documents for the individual requested by the token 100, operating data sets for processing tasks performed using a craftsman device 102 connected to the token 100 via the battery pack 142, and the like. The token 100 can thus be configured to download data sets from the central control device 124 or another communicatively connected node of the communication network 120 via the communication device 118, in particular data sets for operating sequences of the craftsman devices 102 and / or data sets defined in a user profile defining a user of the token 100.

[0083] Furthermore, data can be sent from the token 100 to the central control device 124 via the communication connection between the token 100 and the central control device 124 for storage in the database 132. Such data can be, for example, tracking data that allow the tracking of the craftsman device 102 connected to the respective token 100. Thus, the token 100 can be designed to upload data sets, in particular data sets containing operating results and / or operating parameters of the operation of the craftsman device 102, via the communication device 118 of the control device 124 or another communicatively connected node of the communication network 120.

[0084] Finally, the token 100 can be connected via the communication network 120 to a replenishment ordering device 126 for replenishing and ordering consumables for operating the craftsman device 102 .

[0085] During operation, in order to perform user-related control of the Craftsman device 102 using the token 100, the user of the token 100 can first be identified using the sensor 112 designed as a fingerprint sensor. Subsequently, the mechanical coupling device 110 of the token 100 can be mechanically coupled to the mechanical connection device 152 of the selected battery pack 142 on the Craftsman device 102. Before or after the mechanical coupling, a user profile of the user of the token 100 can be retrieved, for example, in one of the storage devices 128, 132, 139, or 140. After the mechanical coupling, the Craftsman device 102 can be controlled by the processor 106. In this case, the user's use of the Craftsman device 102 can advantageously be permitted, prohibited, and / or deactivated based on the individual's authorization profile.

[0086] Figure 2 FIG. 1 shows a three-dimensional structure consisting of a token 100 and a battery pack 142 inserted into the token 100 according to an exemplary embodiment of the present invention. Figure 4 The interior and the communication device 118 not shown in the figure can be designed as Figure 1 、 Figure 5 or Figure 6 As shown.

[0087] Figure 2 In particular, the interior of the battery block 142 is shown, which is mechanically protected and electrically insulated from the outside by a battery housing 180 (e.g., made of plastic). A plurality of battery cells 181 (e.g., rechargeable battery cells) are arranged inside the battery housing 180 for providing electrical energy. The token receiving portion 152 of the battery block 142 for reversibly receiving the token 100 is accessible to the user from the outside because the token receiving portion is exposed to the outside of the battery housing 180. Figure 2 The token receiving portion 152 of the battery pack 142 is designed as a receiving slot in the battery housing 180. In addition, the figure also shows the electronic circuit board 129 of the battery pack 142, which can be designed as a printed circuit board (PCB). Surface mount components, in particular, the semiconductor chip ( Figure 2 not shown).

[0088] Figure 2The token 100 is shown in an operating state, in which it has been removably inserted into the token receptacle 152 of the battery pack 142. This insertion process allows the battery pack 142 and / or the Craftsman device 102 to be provided with communication functionality via the communication device 118 of the token 100. In other words, by establishing an electromechanical plug connection between the token 100 and the battery pack 142, the communication device 118 enables wireless communication, in particular unidirectional or bidirectional data exchange, between the battery pack 142 or the Craftsman device 102 and a communication partner. This makes it possible to equip or retrofit a battery pack 142 or Craftsman device 102 that is inherently incapable of wireless communication with wireless communication functionality.

[0089] Simultaneously, by inserting the token 100 into the token receptacle 152, a positive-locking and friction-locking connection is formed between the battery block 142 and the housing 101 of the token 100. This is achieved by guiding the lateral guides 105 on the two opposing longitudinal sides of the housing 101 along the positive-locking mating structures 127 formed by the edges of the electronic circuit board 129 in the battery block 142. More specifically, the battery block 142 is equipped with an electronic circuit board 129 configured such that a recess is formed therein that corresponds to the shape and dimensions of the guide rails 105 of the token 100. By inserting or pushing the token 100 into the recess of the electronic circuit board 129, the token 100 can be received in the recess of the electronic circuit board 129 in such a manner that the electronic circuit board 129, as the mating structure 127, engages with the guide rails 105 on the opposing longitudinal sides of the housing 101 in a positive-locking and friction-locking manner. Obviously, the edge of the electronic circuit board 129 that defines the recess forms the mating structure 127. This has the advantage that, because the electronic circuit board 129 not only serves to surface-mount the electronic components of the battery block 142 but also cooperates to form a positive-locking and friction-locking receptacle for the token 100, the structure of the battery block 142 can be kept simple and compact. Furthermore, the direct electromechanical reception of the token 100 by the electronic circuit board 129 enables a very short current path between the token 100 and the battery block 142, thereby ensuring low-interference signal transmission and low-loss energy transfer.

[0090] As described above, the token 100 has a communication device 118 arranged inside the housing 101 for sending a signal to the battery pack 142 and / or the connected battery pack 142 when the token 100 is removably inserted into the token receiving portion 152 of the battery pack 142. Figure 2The communication function is provided by the craftsman device 102 (not shown). At the same time, the housing 101 is inserted into the token receptacle 152 in a form-fitting and friction-locking manner, wherein the lateral guides 105 on the mutually opposing longitudinal sides of the housing 101 are designed for guided insertion into the battery pack 142.

[0091] Figure 2 Also shown is the case 101 in a state where the token 100 is inserted into the battery pack 142. Figure 2 As shown in FIG, the externally accessible end face 113 has a removal aid 117 for manually removing the token 100 from the battery pack 142. The removal aid 117 is designed as a thin removal cord that the user can pull out of the battery pack 142, for example, as a removal cord. The removal cord can be designed as a bow-shaped element, the free end of which is fixed to the housing 101. The grippable center portion of the bow-shaped element protrudes from a removal slot 119 in the otherwise flat end face or end face 113, so that the user can manually grasp the removal cord and pull it out together with the housing 101, thereby pulling the entire token 100 out of the token receptacle 152 of the battery pack 142. By pulling out the token 100, the electrical connection, energy supply connection, and data exchange connection between the token 100 on the one hand and the battery pack 142 and / or the craftsman device 102 on the other hand can be deactivated with a single hand operation.

[0092] Figure 2 It is shown that despite having the above structural features, the housing 101 is generally in the shape of a rectangular parallelepiped.

[0093] Figure 3 A three-dimensional rear view of a token 100 according to an exemplary embodiment of the present invention is shown. Figure 4 A three-dimensional front view of the token 100 is shown.

[0094] With the help of Figure 3 and Figure 4 It can also be shown according to Figure 2 Various structural features are implemented and are described in more detail below. Figure 2 The end face 113 of the token 100 which is accessible from the outside in the assembled state is shown, whereas Figure 3 The illustration shows another end face 115 which is not accessible from the outside in the assembled state and according to Figure 2 , the end side can be adjacent to the electronic circuit board 129 at the end side. Figure 4 It shows that Figure 2 The token 100 has the same front face 113 as the one in FIG.

[0095] first, Figure 3 and Figure 4It is shown that the lateral guide rails 105 can advantageously be formed by guide grooves 107 that are recessed inwardly into the longitudinal sides of the housing 101 that are opposite to each other. This avoids protrusion of functional parts of the housing 101 and thus avoids damage to the token 100 when the user operates the token 100 outside the battery module 142. Figure 3 As shown, the guide groove 107 is a slender groove-shaped depression located on two longitudinal sides of the housing 101 that are opposite to each other. Figure 3 and Figure 4 As shown for one longitudinal side, when the token 100 is pushed into the battery pack 142 in a positive locking and friction locking manner, the lateral guide rails 105 located on the mutually opposite longitudinal sides of the housing 101 can have one or more corresponding locking elements 109 for forming a locking connection between the token 100 and the electronic circuit board.

[0096] Furthermore, the lateral guides 105 on one or more mutually opposite longitudinal sides of the housing 101 can have a centering aid 111 for centering the token 100 in the battery pack 142. The centering aid 111 ensures that the token 100 is correctly positioned laterally relative to the battery pack 142 in the inserted state.

[0097] Figure 3 It is shown that the housing 101 has electrical contacts 156 for forming an electrical connection between the token 100 and the battery block 142 only on the end face 115 which is not accessible from the outside when the token 100 is inserted into the battery block 142. In other words, the electrical connector function of the token 100 is only provided on the rear end face 115, so that the token 100 pushed into the battery block 142 together with the battery housing 180 contributes to the electrical insulation of the outside of the structure. Figure 3 The electrical contacts 156 of the token 100 are provided only on the rear face 115 of the token 100 to form an electrical connection between the token 100 and the battery pack 142. These electrical contacts are electrically connected to the conductive mating contacts of the battery pack 142 by forming a positive and frictional connection with the battery pack 142.

[0098] In order to protect the electrical contacts 156 from moisture when the token 100 is operated outside the battery pack 142, the electrical contacts 156 can be protected from moisture by means of a moisture barrier 121. The moisture barrier 121 can be configured, for example, in the form of an elastomeric lip on or above the electrical contacts 156, which can be displaced or forced to move during the formation of the plug connection to expose the electrical contacts 156. The moisture barrier 121 can also be formed by means of a hydrophobic protective element.

[0099] As best in Figure 3As can be seen in FIG, the housing 101 can have an internally connected stop 123 on the end side 113 that is accessible from the outside in the inserted state, in order to define the insertion depth of the token 100 into the token receptacle 152 of the battery pack 142. Thus, a nominal insertion depth can be specified, which must not be exceeded, because once the nominal insertion depth is reached, the stop 123 abuts against the electronic circuit board 129 and / or other components of the battery pack 143.

[0100] Furthermore, the housing 101 can have an entry bevel 125 adjacent to the end side 115 which is not accessible from the outside in the inserted state, which further improves the lateral positioning accuracy of the token 100 relative to the battery block 143 .

[0101] Figure 5 FIG. 1 shows a top view of the electronic circuit board 184 of the token 100 according to an exemplary embodiment of the present invention. Figure 5 The token 100 shown in FIG. 1 may have a length of 42 mm and a width of 24.5 mm. Figure 6 A three-dimensional structure of a token 100 and a battery block 142 with the token 100 inserted therein is shown according to an exemplary embodiment of the present invention.

[0102] First reference Figure 5 The figure shows a token electronic circuit board 184, which can be designed as a printed circuit board, for example. A plurality of electronic components are mounted on the token electronic circuit board 184. These electronic components include, in particular, the semiconductor chip that constitutes the processor 106. A communication antenna 114, together with the processor 106 or a portion thereof, forms a wireless communication device 118. A sensor module 186 includes one or more sensors 112, as described above. A connector module 188 provides the contacts 156 through which the token 100 is electrically connected to the battery pack 142.

[0103] The communication antenna 114 may be implemented as a Bluetooth or Bluetooth Low Energy (BLE) antenna, for example. Furthermore, the processor 106 may be, for example, a Bluetooth Low Energy (BLE) or Bluetooth processor. Depending on the communication technology implemented, multiple or other processors or antennas may also be used.

[0104] Reference again Figure 5 The communication antenna 114 of the communication device 118 is arranged adjacent to an end side 113 which is accessible from the outside when the token 100 is inserted into the battery block 142 . Figure 6 More precisely, when the token 100 is inserted into the battery pack 142, the communication antenna 114 can be arranged within the outer 20% of the length of the housing 101. Figure 5 and Figure 6The communication antenna 114 of the communication device 118 on the one hand and the electrical contacts 156 or the plug block 188 for establishing an electrical connection between the token 100 and the battery block 142 on the other hand are arranged in longitudinally opposite halves 190 , 192 of the housing 101 . Figure 5 , halves 190 and 192 extend to the left and right, respectively, from centerline 194. This geometry is highly advantageous for both electrical operational reliability and wireless communication quality: Firstly, it ensures that when battery block 142 is electrically coupled to battery block 152, contact portion 156 of token 100 is located deep within battery block 142. Consequently, during operation, the exterior of the structure consisting of token 100 and battery block 142 is reliably electrically insulated. Furthermore, in this configuration, communication antenna 114 is located on the exterior of the structure consisting of token 100 and battery block 142.
