Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates generally to a wireless transmitting apparatus for coupling to an actuation device. [Background technology]

[0002] Under current technology, to control devices / machines in an industrial context, a transmitting device can be used to transmit communication signals to a receiving device in the device / machine, working with either a wired system or a wireless system.

[0003] For a wired transmission device coupled to an actuation device such as a push button, the actuation device can only control or actuate the device / machine that is wired / coupled to the wired transmission device. That is, the wired transmission device cannot control or actuate other devices that are not wired / coupled to the wired transmission device. Another problem that arises with wired transmission devices is that they can only remain fixed in an initially determined location after the wiring is implemented. This can lead to inflexibility during the initial phase of setting up a system or network for an industrial unit or during / after any changes thereto.

[0004] Therefore, for certain applications / systems, a wireless transmitting device is provided. For such a wireless transmitting device, power needs to be provided to a transmitting mechanism inside the transmitting device to transmit a signal to a corresponding receiving device. This can result in a wireless transmitting device having a large form factor, such that only one wireless transmitting device can be connected or coupled to one initiating device. Therefore, it is now recognized that only one initiating device can be associated with one wireless transmitting device. This limits the initiating device to communicate with the receiving device associated with the wireless transmitting device, i.e., the receiving device is limited in remote control functionality.

[0005] Furthermore, for such wireless transmitting devices, the initiation devices are manufactured in a one-to-one relationship with the transmitting device, i.e., each initiation device can only function with or be coupled / connected to a dedicated or specific wireless transmitting device. This can result in increased costs and logistical complexity, as many different customized initiation devices need to be procured for different types or models of transmitting devices. Summary of the Invention [Problem to be solved by the invention]

[0006] In light of the above, therefore, there is a need for a wireless transmitting device and a method of making a wireless transmitting device that seeks to address at least one of the above problems. [Means for solving the problem]

[0016] The contact piece of the cam member may include a protruding end angled toward the translation member for contacting the translation member and a heel portion distal to the protruding end of the cam member, and the method may further include positioning the heel portion to displace it toward the generating mechanism of the generator.

[0017] The method may further include the step of positioning the cam member such that as the contact piece rotates toward the generator, an increasing surface area of ​​the heel portion can contact a generating mechanism of the generator to progressively displace the generating mechanism of the generator and generate electrical power to operate the transmitting device.

[0018] The method may further include the step of disposing at least one conductive member on at least one side wall of the housing, the at least one conductive member being positioned to allow electrical coupling to other devices positioned adjacent to the wireless transmitting device.

DETAILED DESCRIPTION OF THE INVENTION

[0025] 1A is a perspective view of a wireless transmission device in an exemplary embodiment, and FIG. 1B is a perspective view showing exemplary dimensions of the exterior of the wireless transmission device of FIG. 1A.

[0026] 1A, the wireless transmitting device 100 includes a transmitter housing 102, a translating member 104, a cam member (not shown), and a generator (not shown). The wireless transmitting device 100 may additionally include a conductive member 106.

[0027] The transmitter housing 102 includes a first top surface 108, a first sidewall 110, a second sidewall (not shown), a first rear end 112, and a second rear end 113. The first sidewall 110 is opposite the second sidewall (not shown). The first rear end 112 is opposite the second rear end 113. The translational member 104 is located on the first top surface 108 of the transmitter housing 102. An exposed portion of the translational member 104 protrudes above the first top surface 108 of the transmitter housing 102. A cam member (not shown) is located within the transmitter housing 102. A generator (not shown) is located within the transmitter housing 102. In the exemplary embodiment, the generator is capable of generating power to operate the wireless transmitter 100. In the exemplary embodiment, the exposed portion of the translational member 104 protruding above the first top surface 108 is positioned to be contacted by an actuator of an actuator device. For example, such an actuator can be a plunger and the actuation device can be a push button or a selector switch that includes a plunger.

[0028] The wireless transmitting device 100 further includes first mechanical coupling members 114, 115 disposed on the first upper surface 108. The first mechanical coupling members 114, 115 are adapted to mechanically engage or couple with an external actuation device (not shown). The first mechanical coupling members 114, 115 may be in the form of, but are not limited to, a fastening hook and a snap-fastening clip, respectively, for mounting the wireless transmitting device 100 to the external actuation device. The external actuation device may be, but is not limited to, a push button, a toggle switch, a joystick, etc. The push button, toggle switch, joystick, etc. may be made from, but is not limited to, plastic or metal. For example, the external actuation device may be a wired transmitting device with a plunger for actuating the wireless transmitting device. In such a situation, the wired transmitting device may be actuated by another actuation device that further actuates its own plunger to actuate the wireless transmitting device. The first mechanical coupling members 114, 115, when disposed on the first top surface 108, allow the wireless transmitting device 100 to be easily mounted to or dismounted from an external actuation device.

[0029] In the illustrated embodiment, the wireless transmitting device 100 may further include a second mechanical coupling member 116 disposed at the first rear end 112. Another second mechanical coupling member 117 may be provided disposed at the second rear end 113 of the transmitter housing 102. The second mechanical coupling members 116, 117 form a passage extending from the first side wall 110 to the opposing second side wall (not shown). The second mechanical coupling members 116, 117 are adapted to mechanically couple to an adjacent external device (not shown) disposed adjacent to the wireless transmitting device 100, i.e., adjacent to the first side wall 110 and / or the second side wall of the transmitter housing 102, the adjacent external device (not shown) including a complementary member for coupling with the second mechanical coupling members 116, 117.

[0030] In the illustrated embodiment, the wireless transmitter 100 thereby includes a conductive member 106 disposed on the first sidewall 110. In some illustrated embodiments, an additional conductive member, such as reference numeral 106, may be disposed on a second sidewall (not shown) of the transmitter housing 102. In such an illustrated embodiment, the conductive member 106 is provided exposed on each sidewall of the transmitter housing 102, i.e., the first sidewall 110 and / or the second sidewall. The conductive member 106 may be in the form of, but is not limited to, a gold-plated edge, one or more contact pads, or one or more pogo pins. The conductive member 106 enables electrical coupling of the wireless transmitter 100 to other devices disposed adjacent to the wireless transmitter 100 on the first sidewall 110 and / or the second sidewall (not shown). For example, the other devices may include corresponding conductive members to cooperate with the conductive member 106. For example, the conductive member 106 can be one or more exposed contact pads, while the other device can include one or more pogo pins to cooperate with the contact pads. For example, the other device can provide an external power source to the wireless transmitting device via the electrical coupling. For example, sufficient power can be provided via the electrical coupling to cause the wireless transmitting device to receive a confirmation communication signal from the receiving device. For example, the wireless transmitting device can control the other device via the electrical coupling.

[0031] FIG. 1B shows exemplary external dimensions of the wireless transmitter 100 of FIG. 1A. The dimensions are shown to provide a clear distinction between the small form factor of the wireless transmitter of the exemplary embodiment and prior art wireless transmitters in the same field. The height of the transmitter housing 102 from the first upper surface 108 to the second lower surface (not shown) is shown as approximately 23-24 mm, but is not limited thereto. The height does not take into account the height of the exposed portion of the translation member 104 that protrudes above the first upper surface 108, which is approximately 5 mm.

[0032] The width of the transmitter housing 102 from the first side wall 110 to the opposing second side wall (not shown) is shown as approximately 10 mm, but is not limited to such. The second mechanical linkage 116 extends from the first side wall 110 along the entire width of the transmitter housing 102 to the opposing second side wall (not shown).

[0033] The length of the transmitter housing 102 from the first rear end 112 to the opposite second rear end 113 is shown as approximately 32 mm, but is not limited to such. The length includes the distal-most tips of the second mechanical linkage members 116, 117 in the illustrated embodiment.

[0034] Figure 2A is a cross-sectional side view of an exemplary embodiment of a wireless transmitting device, Figure 2B is a cross-sectional side view showing exemplary dimensions of the wireless transmitting device of Figure 2A, and Figure 2C is a schematic enlarged front view of a cam member of the wireless transmitting device of the exemplary embodiment.

[0035] 1A and 1B. The wireless transmitting device 200 includes a translating member 204, a cam member 220, a generator 230, and a circuit board 240. The wireless transmitting device 200 can be actuated via an actuator of an external actuation device (not shown).

[0036] The translational member 204 is located on and extends into a first top surface 208 of a transmitter housing of the wireless transmitter 200. The cam member 220, the generator 230, and the circuit board 240 are located within the transmitter housing. The translational member 204 is arranged to translate toward the cam member 220 relative to the first top surface 208 of the transmitter 204 upon application of a mechanical force to one end of the translational member 204. The mechanical force may be applied to an exposed portion / end of the translational member 204 via an external actuation device (not shown), which may be mechanically engaged with first mechanical linkage members 214, 215 of the wireless transmitter 200.

[0037] The generator 230 can be of any form and type that includes a generating mechanism that can cooperate with the cam member 220 to generate power for operating the wireless transmitting device 200. For example, sufficient power / energy can be generated for the wireless transmitting device 200 to send a communication signal to a receiving device using a transmitting mechanism (not shown). In the illustrated embodiment, the generator 230 is a mechanical generator that generates energy using the principle of induction. The generator 230 includes a generating mechanism in the form of a spring 232. The generator 230 further includes a magnet 234 coupled to the spring 232 and an electromagnetic coil 236. The magnet 234 is movable in the same translational direction as the translation member 204 when the spring 232 is compressed. The magnet 234 moves relative to the electromagnetic coil 236. The spring 232 switches the magnet 234 to move when it exceeds the maximum point of compression. The switching of the magnet 234 and the movement of the magnet 234 relative to the electromagnetic coil 236 generate current to the circuit board 240. The generated current switches on or powers on the microcontroller on circuit board 240, which then transmits a communication signal to a receiving device using a transmitting mechanism (not shown).

[0038] In the illustrated embodiment, the circuit board 240 is disposed along the height of the wireless transmitter 200 in a vertical orientation extending between the first upper surface 208 and the opposite second lower surface of the transmitter housing. The circuit board 240 includes an electrical circuit and an integrated communications module used to control the transmission of at least one communication signal. The circuit board 240 includes a microcontroller, a transmitting mechanism, and a communications tuning element disposed on the circuit board 240. The transmitting mechanism includes an antenna. The transmitting mechanism can transmit the communication signal to the receiving device when power is generated by the generator 230.

[0039] In the illustrated embodiment, cam member 220 is provided such that the properties of a cam system are utilized in wireless transmitting device 200. That is, off-center rotation of the cam member translates the displacement of the cam member into a larger, increasing displacement of the receiving element (compared to spring 232). It is understood that any form of cam member may be used.

[0040] In the illustrated embodiment, the cam member 220 is fixed to the transmitter housing at a fixed point 222. In this illustrated embodiment, the point of rotation of the cam member 220 is at the fixed point 222 of the cam member 220. That is, the cam member 220 is arranged for off-center rotation about the fixed point 222 of the cam member 220.

[0041] 2C , the cam member 220 of the illustrated embodiment includes a contact piece 224 for contacting the translation member 204. The cam member 220 also includes a member body 221. The member body 221 extends between the contact piece 224 and a fixed point 222. As such, the fixed point 222 of the cam member 220 is connected to the contact piece 224 by the member body 221. The cam member 220 is adapted to rotate about the fixed point 222 off-center from the member body 221. As such, the contact piece 224 is at an end of the cam member 220 distal from the fixed point 222.

[0042] In the illustrated embodiment, contact piece 224 includes a protruding end 226 and a heel portion 228. Cam member 220 is shaped such that protruding end 226 is angled toward translation member 204. Heel portion 228 is distal to protruding end 226. Heel portion 228 is positioned above spring 232 of generator 230 and is positioned to be biased toward spring 232.

[0043] The contact piece 224 can contact the translational member 204 at a rotational end of the cam member 220 via a protruding end 226, for example, upon application of a mechanical force to one end of the translational member 204, and can contact a spring 232 of the generator 230 at a heel portion 228. The cam member 220 can rotate about the fixed point 222 such that the contact piece 224 can rotate toward the generator 230 to activate it, and such rotation occurs upon contact between the translational member 204 and the contact piece 224 of the cam member 220.

[0044] Referring to FIG. 2B, some exemplary internal dimensions of the wireless transmitter 200 of FIG. 2A are shown. The dimensions are shown to provide a clear distinction between the small form factor of the wireless transmitter of the exemplary embodiment and prior art wireless transmitters in the same field. The height of the transmitter housing from the first upper surface 208 to the second lower surface is shown as, but is not limited to, approximately 23.6 mm. The height of the exposed portion of the translation member 204 that protrudes upward beyond the first upper surface 208 of the transmitter housing is shown as, but is not limited to, approximately 4.99 mm. In the unactuated state (i.e., when the translation member 204 is not being moved by an external actuation device), the distance from the lowest portion of the heel portion 228 to the first upper surface 208 of the transmitter housing is shown as, but is not limited to, approximately 7.67 mm. In the unpowered state, the distance from the lowest portion of the generator 230 to the first top surface 208 of the transmitter housing is shown as, but is not limited to, approximately 20.74 mm.

[0045] Figure 3A is a schematic diagram illustrating the respective positions of various components of a wireless transmission device in an initial first position in an exemplary embodiment, Figure 3B is a schematic diagram illustrating the respective positions of various components of a wireless transmission device in an intermediate second position in an exemplary embodiment, and Figure 3C is a schematic diagram illustrating the respective positions of various components of a wireless transmission device in a final third position in an exemplary embodiment.

[0046] In this exemplary embodiment, the translational member 304 is in the form of a plunger, although it will be understood that the translational member 304 is not limited as such.

[0047] 3A, the various components of the wireless transmission device 300 are in an initial first position when no force is applied to the translational member 304 of the wireless transmission device 300. This state may be referred to as an unactuated state.

[0048] In the initial first position, the cam member 320 may be away from or in minimal contact with the spring 332 of the generator 330 of the wireless transmitting device 300. The generator 330 is in an inactive state.

[0049] An external mechanical force F may be applied to the translational member 304 to actuate or operate the wireless transmission device 300. For example, an external actuation device (not shown) may be mechanically engaged with the first mechanical linkage member 314 of the wireless transmission device 300. The external actuation device may include a plunger / piston positioned in mechanical contact with the translational member 304 of the wireless transmission device 300.

[0050] As shown in FIG. 3B, application of an external mechanical force F causes various components of the wireless transmission device 300 to be shown in an intermediate second position, i.e., in actuation of the wireless transmission device 300.

[0051] Referring to FIG. 3B , when an external mechanical force F is applied to an external actuating device (not shown), the piston of the external actuating device pushes the translational member 304 of the wireless transmitting device 300. Therefore, the external mechanical force F causes the translational member 304 to translate downward in a substantially vertical direction toward the cam member 320. When the translational member 304 contacts the protruding end 326 of the contact piece 324 of the cam member 320, the cam member 320 begins to rotate / pivot off-center from the member body 321 of the cam member 320, and the rotation is in a first direction about the fixed end 322. The first direction is downward, toward the spring 332 of the generator 330. Referring to FIG. 3B , the first direction is counterclockwise. The cam member 320 is displaced with an increasing displacement downward during the rotation process in the first direction.

[0052] At a certain point during the rotation of cam member 320 in the first direction, heel portion 328 of contact piece 324 of cam member 320 begins to contact spring 332 of generator 330. As cam member 320 continues to rotate in the first direction about fixed end 322, heel portion 328 contacts and pushes spring 332 downward. As contact piece 324 rotates in the first direction toward generator 330, the increasing surface area of ​​heel portion 328 contacts and progressively displaces spring 332 of generator 330 to ultimately generate power to operate wireless transmitting device 300.

[0053] 3B, the spring 332 of the generator 330 is compressed when the heel portion 328 of the cam member 320 pushes down on the spring 332. The magnet 334 of the generator 330 is mechanically connected to the spring 332 via a lever 342. When the spring 332 is compressed, energy accumulates in the spring 332. The magnet 334 remains in the same position between the initial first position and the intermediate second position due to the magnetic force of the magnet 334.

[0054] Referring to FIG. 3C , when spring 332 is maximally displaced due to contact with cam member 320, the force of spring 332 becomes greater than the magnetic force of magnet 334. Spring 332 is straightened, and the force of spring 332 displaces lever 342, which further translates magnet 334 downward, e.g., abruptly, toward the bottom of the transmitter housing, until magnet 334 reaches a third and final position as shown in FIG. 3C . Compare the positions of magnet 334 in FIGS. 3B and 3C . Thus, magnet 334 moves relative to stationary electromagnetic coil 336 of generator 330. The movement of magnet 334 induces a voltage and a current in stationary electromagnetic coil 336 of generator 330.

[0055] At this stage, the generator 330 is thereby actuated by the actuation of the wireless transmitting device 300 via the translational member 304. The actuation / induction generates sufficient energy / power to realize the functionality of the wireless transmitting device 300. The wireless transmitting device 300 is powered, and the generator 330 provides power, including powering a transmitting mechanism disposed on a circuit board 340 in the wireless transmitting device 300, for example, to transmit one or more communication signals to a corresponding receiving device. For example, a microcontroller on the circuit board 340 can be activated by generating power, and three wireless frame transmissions can be sent to the receiving device. The frequencies of the one or more signals can be stored in a memory module on the circuit board 340.

[0056] In the illustrated embodiment, the various components of the wireless transmitting device 300 are in a third and final position, as shown in Figure 3C, in which the magnet 334 of the generator 330 is in its final position, having been moved down from the initial first position and the intermediate second position, and the generator 330 is activated.

[0057] In the illustrated embodiment, when mechanical force F is removed, the components return to their initial positions as shown in FIG. 3A. For example, spring 332 is biased to return toward the initial first position shown in FIG. 3A. The movement of spring 332 causes lever 342 to pull magnet 334 upward from the final third position toward the first top surface of the transmitter housing. At a certain point, spring 332 returns to the initial first position, and magnet 334 moves, for example, abruptly, back to the initial first position as shown in FIG. 3A. The return of spring 332 rotates / pivots cam member 320 about fixed end 322 in a second direction, off-center from member body 321 of cam member 320, until cam member 320 returns to the initial first position as shown in FIG. 3A. The second direction is upward, toward translation member 304. Referring to FIG. 3B, the second direction is clockwise. This causes translational member 304 to move back to the initial first position. No external force needs to be applied to move the component from the final third position of Figure 3C back to the initial first position of Figure 3A.

[0058] In the illustrated exemplary embodiment involving the arrangement of a translational member (e.g., compared to translational member 204 in FIG. 2A ) and a cam member (e.g., compared to cam member 220 in FIG. 2A ), the translational member may be provided with a shorter length / height compared to other such devices. With the cam member, the translational member can function with different travel distances of different actuators, thereby enabling the wireless transmission device of the exemplary embodiment to function with different actuation devices. For example, the translational member only needs to travel a short distance to rotate the cam member (e.g., compared to spring 232 of generator 230 in FIG. 2A ), which in turn progressively displaces the generator's generating mechanism. The short distance is sufficient as long as the translational member can contact cam member 220, which performs an off-center rotation to progressively displace the generator's generating mechanism, e.g., to switch the magnets of generator 230. Therefore, different actuators with different travel distances may be accommodated to function with the translational member.

[0059] 1B and 2B , the small form factor of the wireless transmitter devices of the described exemplary embodiments allows the wireless transmitter devices to be mounted in different configurations to complement existing wired systems or as stand-alone wireless contact blocks. For example, multiple wireless transmitter devices can be mounted together with a single external mobilization device or mechanically coupled to a single external mobilization device. As another example, a wireless transmitter device can be mounted to a wired transmitter device or mechanically coupled to a wired transmitter device, which can then be coupled to a single external mobilization device. For example, a wireless transmitter device can be mounted adjacent to a wired transmitter device, and both transmitter devices are coupled to the external mobilization device.

[0060] FIG. 4A is a schematic diagram of a wireless transmitting device mounted on a wired block in an exemplary embodiment.

[0061] Due to the arrangement of the translation member and cam member of the wireless transmitter, the wireless transmitter can function usefully with actuators of wired contact blocks, i.e., the wireless transmitter can function with actuators with different travel distances.

[0062] As shown in FIG. 4A , two wired contact blocks 404, 406 are coupled to an actuation device 408 in the form of a push button. The wired contact blocks 404, 406 can be, but are not limited to, wired transmitting devices. A wireless transmitting device 402 is mounted under one of the two wired contact blocks 404, 406. For example, the wireless transmitting device 402 is shown mounted on the wired contact block 406. In this illustration, the actuation device external to the wireless transmitting device 402 is the wired contact block 406. The actuation device 408 can be used to perform actuation at the two wired contact blocks 404, 406, for example, via an actuator (not shown) of the actuation device 408. As a result of coupling of the wireless transmitting device 402 to the wired contact block 406, actuation from the actuation device 408 further actuates an actuator (not shown) of the wired contact block 406, thereby effecting actuation of the wireless transmitting device 402, i.e., at its translation member (not shown).

[0063] FIG. 4B is a schematic diagram of a wireless transmitting device mounted adjacent to a wired block in an exemplary embodiment.

[0064] The described arrangement of the wireless transmitting device of the exemplary embodiment results in a small form factor, allowing the wireless transmitting device to fit into any existing actuation control device while still leaving enough space for other contact blocks, which may be other wireless transmitting devices, other similar or identical wireless transmitting devices of the exemplary embodiment, and / or wired contact blocks.

[0065] As shown in FIG. 4B, two wired contact blocks 404, 406 are coupled to an actuation device 408 in the form of a push button. The wired contact blocks 404, 406 can be, but are not limited to, wired transmitting devices. A wireless transmitting device 402 is mounted on the actuation device 408 and is adjacent to the two wired contact blocks 404, 406. In this illustration, the actuation device external to the wireless transmitting device 402 is the actuation device 408. The actuation device 408 can be used to perform actuation at the wireless transmitting device 402 and the two wired contact blocks 404, 406, for example, via an actuator (not shown) of the actuation device 408.

[0066] 4A and 4B, the small form factor and ability to function with different actuator travel distances allows for functionality and wireless communication to one or more receiving devices to be added to the actuation device 408. For example, actuation device 408 can control devices / industrial units at one or more receiving devices in communication with wireless transmitting device 402.

[0067] 5 is a schematic flow chart 500 illustrating a method for activating a wireless transmission device in an exemplary embodiment. In the method, the wireless transmission device is a battery-less wireless transmission device. The wireless transmission device is substantially similar to the wireless transmission devices of other exemplary embodiments (e.g., compare with the wireless transmission devices 100 and 200 of FIGS. 1A and 2A, respectively).

[0068] In step 502, an external actuation device is mounted and positioned on the wireless transmitting device. In step 504, a user or operator actuates the external actuation device, and the actuator of the external actuation device transmits mechanical force to actuate the translational member of the wireless transmitting device. In step 506, the translational member translates toward the cam member and contacts a contact piece of the cam member of the wireless transmitting device. In step 508, the cam member rotates about a fixed point of the cam member, and the contact piece rotates toward the generator of the wireless transmitting device to activate the generator. In step 510, the contact piece contacts a generating mechanism of the generator, gradually displacing the generating mechanism of the generator and generating power to operate the transmitting device. In step 512, a microcontroller of the wireless transmitting device receives the generated power and is activated. In step 514, the microcontroller commands the transmitting mechanism to transmit a communication signal.

[0069] In an exemplary embodiment, the transmission may be based on a predetermined frequency stored in and retrieved from a memory module of the wireless transmitting device, and the content of the transmission may be dictated by a microcontroller and / or may be stored in and retrieved from a memory module of the wireless transmitting device.

[0070] FIG. 6 is a schematic flow chart 600 illustrating a method for fabricating a wireless transmitting device in an exemplary embodiment.

[0071] In step 602, a transmitter housing having a first top surface is provided. In step 604, a translation member is disposed on the first top surface of the transmitter housing. In step 606, a cam member is disposed within the transmitter housing, the cam member being disposed to rotate about a fixed point on the cam member, the cam member comprising a contact piece for contacting the translation member, and further comprising a member body extending between the contact piece and the fixed point on the cam member. In step 608, a generator is disposed within the transmitter housing to generate power for operating the transmitter. In step 610, the translation member is disposed to translate toward the cam member and to contact the contact piece of the cam member upon application of a mechanical force. In step 612, the cam member is disposed to rotate about the fixed point to rotate the contact piece toward the generator to activate the generator, the rotation occurring upon contact between the translation member and the contact piece of the cam member.

[0072] In an exemplary embodiment, the contact piece of the cam member may include a protruding end angled toward the translation member for contact with the translation member and a heel portion distal to the protruding end of the cam member, and the method may further include positioning the heel portion to displace toward the generating mechanism of the generator.

[0073] In an exemplary embodiment, the method may further include positioning the cam member such that as the contact piece rotates toward the generator, an increasing surface area of ​​the heel portion can contact a generating mechanism of the generator to progressively displace the generating mechanism of the generator and generate electrical power to operate the transmitting device.

[0074] In an exemplary embodiment, the method may further include the step of disposing at least one conductive member on at least one side wall of the housing, the at least one conductive member being positioned to enable electrical coupling to another device positioned adjacent to the wireless transmitting device.

[0075] In an exemplary embodiment, the method may further include disposing the transmitting mechanism on a circuit board and disposing the circuit board in a vertical orientation extending between a first upper surface and an opposite second lower surface of the housing.

[0076] In an exemplary embodiment, the transmitting mechanism may transmit a communication signal when power is generated by the generator.

[0077] In an exemplary embodiment, the method may further include disposing a first mechanical coupling member on the first upper surface and adapting the first mechanical coupling member to mechanically engage with an external actuation device disposed on the first upper surface.

[0078] In an exemplary embodiment, the method may further include the steps of disposing a second mechanical coupling member at a back end of the housing and adapting the second mechanical coupling member to mechanically couple with an external device disposed adjacent to the wireless transmitting device.

[0079] The above exemplary embodiments can provide a battery-less wireless transmitting device. The wireless transmitting device can be modular in form. The wireless transmitting device can be activated by a main control unit and used to send a wireless signal to a receiving device / receiver. The wireless transmitting device of the described exemplary embodiments can be a self-powered contact block that can be connected to a wide range of industrial control devices for industrial units.

[0080] In the described exemplary embodiment, a plunger and pivoting arrangement is employed in the wireless, battery-free transmitting device in the form of a translation member and a cam member. The cam arrangement / system allows the wireless, battery-free transmitting device to function with external actuation devices with different travel distances in the actuation mechanisms of each of the external actuation devices. Therefore, the described exemplary embodiment of the wireless, battery-free transmitting device is not limited to function / operate with a particular type of external actuation device. The wireless transmitting device of the exemplary embodiment with the cam arrangement / system can function with and accommodate a variety of different external actuation devices with different travel / translation distances of the respective actuators / plungers. Therefore, it is not necessary to provide a particular type of external actuation device to function / operate with the wireless transmitting device.

[0081] Additionally, the wireless transmitting device of the described exemplary embodiment can be coupled to a wired transmitting device, which can be further coupled to an actuation device, such that the wireless transmitting device of the exemplary embodiment can function with different travel distances of the actuator, thereby allowing the wired transmitting device to actuate the wireless transmitting device of the exemplary embodiment.

[0082] The inventors have recognized that currently, wired transmitting devices cannot be coupled to wireless transmitting devices. With a cam arrangement / system, a wireless transmitting device can be usefully coupled or connected to a wired transmitting device to add new functionality to a device / machine. For example, an external actuation device, such as a push button, already coupled to a wired transmitting device may be expanded to control a new system / device in a new receiving device that communicates with the wireless transmitting device of the exemplary embodiment. In this regard, multiple functions can be realized with a single external actuation device. For example, the external actuation device can simultaneously control the on / off state of a machine via wired communication and send a wireless communication signal via the wireless transmitting device to a corresponding receiving device that can collect information during the on / off cycle. Other new functions may also be added, such as information gathering for condition monitoring and / or data collection on the device / machine.

[0083] Furthermore, the inventors have now recognized that only one wireless transmitter can be coupled to the external actuation device, i.e., a one-to-one coupling. With the plunger and pivot arrangement, i.e., cam arrangement / system, the translation distance for the translation member to activate the generator is minimized and shortened. Therefore, the length of the translation member is also minimized and shortened. The height of the wireless, battery-less transmitter of the exemplary embodiment can be made much smaller, resulting in a significantly smaller form factor or a significantly smaller wireless transmitter. The small generator used in conjunction with the plunger and pivot arrangement can also contribute to the small form factor. The small form factor achieved for the wireless transmitter thereby allows for more than one wireless transmitter to be coupled to the external actuation device, i.e., the wireless transmitter of the exemplary embodiment is modular in nature.

[0084] In the described exemplary embodiment, an integrated communication module with a microcontroller and a transmitting mechanism including an antenna and a communication tuning element disposed on a circuit board is used in the wireless transmitting device. The use of the integrated communication module can perform both the role of controlling the circuit and the role of sending communication signals. This can result in a compact wireless transmitting device because all functions can be integrated into a single microchip.

[0085] In the described exemplary embodiment, the circuit board is positioned in a vertical orientation in the wireless transmitting device. The vertical orientation of the circuit board allows for spatial optimization. The antenna of the circuit board is also located closer to the top of the wireless transmitting device. This allows for a stronger communication signal sent by the wireless transmitting device to each receiving device. The vertical orientation also contributes to a small form factor of the wireless transmitting device.

[0086] In the described exemplary embodiment, a conductive member disposed on at least one sidewall of the transmitter housing provides a connection interface for an external device disposed adjacent to the wireless transmitter, which can avoid the need for a relatively large electrical conductor / input module on a circuit board or on a surface of the wireless transmitter, thereby allowing other devices to be disposed directly adjacent to the wireless transmitter.
