Abstract
Description
Technical Field
[0001] This invention relates to a mobile lubrication pump or distribution station, and a method for adjusting the pump pressure of the mobile lubrication pump. Background Technology
[0002] To ensure the proper operation of most machines, regular and frequent lubrication is necessary. Lubrication can be achieved through a fixed lubricator integrated into a single machine. Alternatively, lubrication can be achieved through a mobile lubricator that can serve multiple machines. For example, the mobile lubricator can be portable or transportable, making it easy, for example, to be transported by a person to / from different lubrication targets.
[0003] A lubricator typically includes a lubricant pump that generates pump pressure for distributing lubricant. Additionally, the lubricator includes a pump drive (e.g., a motor) and a pump drive controller (e.g., a motor controller). To ensure safe operation, the lubricator typically includes means for preventing overpressure within the pump and / or its components (e.g., pipes). For example, the lubricator may include a pressure relief valve or a safety valve. Alternatively, the lubricator may be limited to operation at lower capacity pressures and / or lower motor speeds, thereby reducing the risk of harmful overpressure. Further alternatively, the lubricator may include a pressure gauge for detecting predetermined harmful overpressure.
[0004] WO 2013 / 034154 discloses a mobile lubrication unit comprising a motor-driven pump, a motor controller, and a pressure gauge. The motor controller controls the operation of the motor based on input from the pressure gauge, such that the motor is stopped by the controller at a predetermined critical maximum pressure. The predetermined maximum pressure can be provided to the controller via an input panel.
[0005] To check and ensure adequate lubrication of a target object (e.g., a bearing), the bearing can be lubricated until a predetermined volume of lubricant / grease has been introduced and fresh grease flows out of the bearing vent, or a certain back pressure is measured. This method is also known as the grease removal and volumetric (GPV) method.
[0006] Different lubrication targets typically require different amounts of grease to ensure adequate lubrication, and these targets generate different back pressures and back pressure rates. Therefore, the first bearing needs and can withstand high lubricant pressures for effective lubrication, resulting in a correspondingly high back pressure, while the second bearing can withstand only low lubricant pressures for effective lubrication. Consequently, if the lubrication pressure is not properly regulated, there is a risk that the lubrication system may damage the second lubrication target.
[0007] To further improve lubrication safety and efficiency, improvements to mobile lubricators are needed. Summary of the Invention
[0008] This invention provides a mobile lubrication pump with improved safety and efficiency. High combined safety and efficiency are particularly important for mobile lubricators, where different lubrication targets require different lubrication pressures to achieve optimal lubrication, and where different pumps can withstand different back pressures and overpressures.
[0009] A first aspect of the present invention relates to a mobile lubrication pump, comprising:
[0010] - Motor, used to drive the pump to generate pump pressure.
[0011] - Pressure monitor, used to measure pump pressure.
[0012] - Motor controller, used to regulate the operation of the motor.
[0013] - Data processing unit (DPU) for communicating with the motor controller and for receiving: 1) input from the pressure monitor, and 2) user input related to pump capacity and / or lubrication targets, and
[0014] The data processing unit is configured to determine the motor speed and / or motor torque based on the received inputs 1) and 2) and transmit the motor speed and / or motor torque to the motor controller.
[0015] A second aspect of the present invention relates to a method for adjusting the pump pressure of a portable lubrication pump, comprising the following steps:
[0016] a) Provide a mobile lubrication pump including a motor.
[0017] b) Provide at least one conditional parameter via a communication device, wherein the conditional parameter is related to pump type, lubrication target, pump pressure, pump speed and / or pump flow rate.

[0020] In a preferred embodiment, the method is a computer-executed method. Attached Figure Description
[0021] The invention will now be described in more detail with reference to the accompanying drawings, in which:
[0022] Figure 1 A view is shown of an embodiment of a mobile lubrication pump according to the present disclosure.
[0023] Figure 2A and Figure 2B An embodiment of a mobile lubrication pump according to the present disclosure is shown, wherein the pump and the user interface form an integrated unit.
[0024] Figure 3A and Figure 3B An embodiment of a mobile lubrication pump according to the present disclosure is shown, wherein the user interface includes a wireless communication device, and wherein the DPU optionally includes a computer implementation. Detailed Implementation
[0025] The invention is described below with reference to the accompanying drawings. Those skilled in the art will understand that the same features or components of the apparatus are designated by the same reference numerals in different drawings. A list of reference numerals can be found at the end of the detailed description section.
[0026] Figure 1 An embodiment of a mobile lubrication pump or dispensing station according to this disclosure is shown for dispensing lubricant or grease from container 7 to lubrication points or more specifically to lubrication targets 8. Examples of lubrication targets include bearings, chains, grease fittings, and grease nozzles. Lubrication targets may also be referred to as lubrication points or lubrication oil points. The system includes a pump 1 mechanically connected to a motor 2 for driving the pump, wherein the motor operation is regulated by a motor controller 3. The system also includes: a pressure monitor 4 for measuring pump pressure; and a data processing unit (DPU) 5 for communicating with the motor controller and for receiving input from the pressure monitor. The DPU is also configured to receive user input, for example, via a user interface 6, wherein the user input relates to pump capacity and / or lubrication targets.
[0027] advantage
[0028] To achieve a rapid lubrication process, it is advantageous to operate the mobile lubrication pump at maximum capacity (e.g., at maximum pressure). However, lower pressures are typically required to protect the target object being lubricated and for the maintenance of the pump and its components.
[0029] Different lubrication targets typically require different amounts of grease to ensure adequate lubrication. Furthermore, different lubrication targets generate different back pressures and back pressure rates. Therefore, the first bearing needs and can withstand high lubricant pressures for effective lubrication, and correspondingly generates high back pressure, while the second bearing can withstand only low lubricant pressures for effective lubrication.
[0030] When using a mobile lubrication pump, the risk of exposing the target lubrication point to inefficient lubrication is particularly high. For example, to protect the target lubrication point and reduce the risk of exposing it to intolerable high pressure, pump operation is typically set to safe values, below the maximum pump capacity and below the maximum tolerable lubricant pressure at the specific target. Alternatively, manual monitoring and control are used to reduce the risk of intolerable high pressure, as well as the risk of excessively low pressure and thus slowing down the lubrication process.
[0031] Different pumps have different pump capacities (i.e., different target or optimal capacities) at which they operate most efficiently to generate the pump pressure used to distribute lubricant. Therefore, the term "pump capacity" refers to the target load on the pump during operation, at which it operates most efficiently.
[0032] Furthermore, pump capacity or target capacity depends on back pressure. Therefore, under no back pressure / low back pressure, the pump capacity / target capacity is higher than under high back pressure. Pump capacity can be explicitly determined by pump type and / or pump parameters such as target pump pressure, target pump speed, and / or target pump flow rate. Pump parameters are interrelated. Therefore, target pump speed can be converted to an equivalent maximum pump pressure. Similarly, target pump flow rate can be converted to an equivalent maximum pump pressure.
[0033] When using a mobile lubrication pump, the risk of operating the pump under overload or underload conditions (i.e., operating above or below pump capacity / target capacity, respectively) is particularly high. For example, if the target lubrication point tolerates high lubricant pressure, the pump may overload due to high back pressure, or if the target lubrication point tolerates low lubricant pressure, the pump may underload to ensure the protection of the target lubrication point.
[0034] It has been found that a more efficient lubrication process can be achieved by adjusting pump operation based on measured pump pressure relative to a given pump capacity and / or lubrication target.
[0035] In one embodiment of this disclosure, a mobile lubrication pump includes:
[0036] - Motor, used to drive the pump to generate pump pressure.
[0037] - Pressure monitor, used to measure pump pressure.
[0038] - Motor controller, used to regulate the operation of the motor.
[0039] - Data processing unit (DPU) for communicating with the motor controller and for receiving: 1) input from the pressure monitor, and 2) user input related to pump capacity and / or lubrication targets, and
[0040] The data processing unit is configured to determine the motor speed and / or motor torque based on the received inputs 1) and 2) and transmit the motor speed and / or motor torque to the motor controller.
[0041] In another embodiment, the pump capacity is determined by the pump type, pump pressure, pump speed, and / or pump flow rate.
[0042] Data Processing Unit (DPU)
[0043] Advantageously, the pump operation is regulated by a motor controller that communicates with a data processing unit (DPU). The DPU is able to receive: (1) input from a pressure monitor that records pump pressure, and (2) input from the user relating to pump capacity and / or lubrication targets. Based on inputs (1) and (2), the DPU can determine or calculate a desired target motor speed, which is the motor speed corresponding to the target pump capacity at the measured pressure and / or the motor speed corresponding to the tolerable lubricant pressure at the lubrication target.
[0044] Therefore, the DPU determines a desired target motor speed that is not zero. For example, if the measured pressure (1) is higher than the known equivalent pump capacity from (2) at the measured pressure, the calculated target motor speed and / or motor torque will decrease. Conversely, if the measured pressure (1) is lower than the known equivalent pump capacity from (2) at the measured pressure, the calculated target motor speed and / or motor torque will increase. Specifically, this has the advantage of avoiding the risk of pump or component overload. With conventional pump controllers, if the measured pressure is high, the motor speed is not adjusted, resulting in the risk of pump overpressure or overload. However, with this disclosure, instead, the high measured pressure is compensated for by adjusting the speed, thereby reducing back pressure, which contributes to more efficient lubrication and pump operation.
[0045] Advantageously, the DPU is configured to continuously receive input from the pressure monitor, such that the desired target motor speed can be known at any point during operation, thereby enabling the pump to be operated most efficiently. More advantageously, the DPU is configured to minimize the difference between inputs (1) and (2), advantageously obtained in a closed feedback loop.
[0046] In one embodiment of this disclosure, the DPU is configured to continuously receive input from a pressure monitor. In another embodiment, the DPU is configured to minimize the difference between inputs 1) and 2). In yet another embodiment, the DPU is configured to minimize the difference in a closed feedback loop.
[0047] Motor controller
[0048] Advantageously, the DPU continuously transmits the calculated target motor speed and / or motor torque to the motor controller, thereby adjusting the motor speed and / or motor torque to the desired target motor speed. The motor controller can be configured to continuously regulate the operation of the motor, thereby achieving continuous and efficient operation of the pump. Alternatively or in combination, the motor controller can be configured to discontinuously regulate the operation of the motor; for example, the motor can be stopped and subsequently restarted at the desired target motor speed after a predetermined amount of time. Preferably, the motor restarts after the predetermined amount of time, such that the pump system is balanced before restarting.
[0049] In one embodiment of this disclosure, the motor controller is configured to continuously regulate the operation of the motor. In another embodiment, the motor controller is configured to discontinuously regulate the operation of the motor.
[0050] The speed and / or torque of a motor can be adjusted using various methods. For example, the motor speed can be adjusted by changing the motor's rotation per unit of time, thereby regulating the motor's operation. For an electric motor, the motor torque is adjusted by changing the power supplied to the electric motor, thereby regulating the motor's operation.
[0051] In one embodiment of this disclosure, the motor controller is configured to regulate motor speed and / or motor torque.
[0052] To improve the cost efficiency of mobile pumps, it is advantageous to include as few components as possible. Therefore, it is advantageous for the DPU and motor controller to be integrated units, such as frequency converters.
[0053] In one embodiment of this disclosure, the DPU and the motor controller are integrated units.
[0054] Any type of motor and motor controller can be used. However, certain combinations of motors and motor controllers can result in more precise controlled regulation. Advantageously, the motor is an electric motor, examples of which include DC motors and AC motors. For example, advantageously, the motor is a brushless DC motor (BLDC) with associated controllers and drivers (such as voltage-controlled drivers), where motor speed and / or motor torque are controlled by means of modulated pulses (PWM) by changing the motor voltage. Alternatively, the motor can be a permanent magnet AC motor (PMAC) with associated controllers and drivers (such as frequency-controlled drivers), where motor speed and / or motor torque are controlled by means of modulated pulses (PWM) by changing the motor frequency and motor voltage.
[0055] User input
[0056] To enhance user-friendliness and security, the DPU is advantageously configured to receive user input via a communication device, such as a wireless device. For example, if the communication device is a mobile phone, the DPU can wirelessly receive input via a near-field coupling receiver, a Bluetooth receiver, and / or an antenna configured to receive signals via the wireless internet or to receive frequency-banded signals transmitted by the mobile phone. Examples of wireless devices include tablets, smartphones, laptops, or devices equipped with near-field coupling or Bluetooth.
[0057] In one embodiment of this disclosure, user input is received via a communication device. In another embodiment, the communication device is a wireless device, such as a tablet computer, smartphone, laptop computer, or a device equipped with near-field coupling or Bluetooth.
[0058] To further enhance user-friendliness, security, and reduce the risk of human error, user input can be obtained via a tag reader configured to read tags associated with pump capacity and / or lubrication targets, or via a scanning device configured to read labels associated with pump capacity and / or lubrication targets. Advantageously, the tags / labels are located at or adjacent to the mobile pump and / or lubrication target.
[0059] In one embodiment of this disclosure, user input is obtained via a scanning device configured to read markers associated with pump capacity and / or lubrication targets.
[0060] To improve the cost efficiency of mobile pumps, it is advantageous to include as few parts as possible. Therefore, it is advantageous for user input to be received manually, for example, via a panel or potentiometer.
[0061] In one embodiment of this disclosure, user input is received manually, such as via a panel or potentiometer.
[0062] pressure monitor
[0063] Different devices can be used to monitor pump pressure. Advantageously, the pressure monitor is placed adjacent to the lubricant dispenser so that the measured pump pressure is accurate and approximates the pressure experienced by the lubricant target. Therefore, the pressure monitor can be a pressure sensor or pressure gauge placed in an open circuit between the lubricant container and the lubricant dispenser.
[0064] Alternatively, and to improve the cost efficiency of mobile pumps, pump pressure can be derived from pump operating parameters. For example, for pumps driven by electric motors, motor current is directly related to pump pressure.
[0065] In one embodiment of this disclosure, the pressure monitor is placed in an open circuit. In another embodiment, the pressure monitor is a pressure sensor. In yet another embodiment, the pressure monitor is a pressure-derived pump parameter that derives pressure.
[0066] pump
[0067] Because the DPU and motor controller determine the desired target motor speed and adjust the motor speed based on the measured pressure, more efficient pump operation and motor regulation are achieved for pumps that provide a smooth pressure profile. Examples of pumps with a smooth pressure profile include gear pumps and rotary piston pumps. In contrast, piston pumps will have a pressure profile with peaks, where the peaks occur after each push.
[0068] In one embodiment of this disclosure, the pump is selected from the group consisting of piston pumps, gear pumps, and rotary piston pumps. In another embodiment, the pump is selected if it is not a piston pump.
[0069] Use of mobile pumps
[0070] To improve the flexibility and mobility of mobile pumps, the pumps advantageously include a power source (such as a battery) to power the motor, motor controller, and / or DPU.
[0071] In one embodiment of this disclosure, the pump also includes a power source, such as a battery.
[0072] Advantageously, the data processing unit includes a computer-implemented method for adjusting the pump pressure of the mobile lubrication pump. Alternatively, the data processing unit includes a software application that can be executed on a remote device.
[0073] A computer-executed method for regulating the pump pressure of a mobile lubrication pump includes the following steps:
[0074] a) Provide a mobile lubrication pump including a motor.
[0075] b) Provide at least one conditional parameter via a communication device, wherein the conditional parameter is related to pump type, lubrication target, pump pressure, pump speed and / or pump flow rate.
[0076] c) Measure the pump pressure.
[0077] The speed of the motor is determined and adjusted based on the inputs in b) and c).
[0078] Example
[0079] The invention is further described by the examples provided below.
[0080] Example 1: A portable lubrication pump with an integrated user interface
[0081] Figure 2A An embodiment of a mobile lubrication pump or dispensing station according to this disclosure for dispensing lubricant or grease from container 7 to lubrication target 8 is shown. The system includes a pump 1 connected to a motor 2 for driving the pump, wherein the motor operation is regulated by a motor controller 3. The pump, motor, and motor controller are illustrated as an integrated unit. The pump also includes a pressure monitor 4 for measuring pump pressure via pressure-derived pump parameters, such as the current flowing in the pump motor.
[0082] The system also includes a data processing unit (DPU) 5, which communicates with the motor controller and receives input from the pressure monitor. The DPU is also configured to receive user input, for example, via a user interface 6 (such as a panel or potentiometer), where the user input is related to pump capacity and / or lubrication targets. For example, the user input may be related to pump capacity (e.g., a target pump pressure), which is the maximum pump pressure considered for effectively operating a certain type of pump under any conditions. The target pump pressure may be indicated by a marking on the pump.
[0083] To achieve a compact mobile pump with a small number of components, it is advantageous to integrate the pump, motor, motor controller, pressure monitor, DPU, and user interface into a single unit, such as... Figure 2A As shown.
[0084] Different lubrication targets require different amounts of grease to ensure adequate lubrication. Furthermore, different lubrication targets generate different back pressures and back pressure rates. Therefore, the first bearing needs and can withstand high lubricant pressures for effective lubrication, and correspondingly generates high back pressure, while the second bearing can withstand only low lubricant pressures for effective lubrication. To ensure effective and safe lubrication of the targets, the targets can be marked with information on permissible lubrication conditions, such as the maximum permissible lubrication pressure.
[0085] Different pumps have different pump capacities (i.e., different target or optimal capacities) which operate most efficiently to generate the pump pressure used to dispense lubricant. To ensure efficient and safe operation of the pump, pumps are typically labeled with their pump capacity based on their pump type, as described above.
[0086] When using the mobile lubrication pump according to this disclosure, the mobile pump is first moved to the vicinity of the lubrication target. At the lubrication target, a reader can receive information related to the lubrication target, as well as the pump capacity. The user then transmits input related to the pump capacity and / or lubrication target to the DPU, for example, via a potentiometer user interface.
[0087] During pump operation, a pressure monitor monitors any changes in pump pressure. For example, the pressure may gradually increase due to an increase in back pressure. The pressure monitor transmits the monitored pressure to the DPU, and based on the actual measured pressure and inputs related to pump capacity and / or lubrication targets, the DPU can calculate or determine motor speed and / or motor torque, which will adjust the pump pressure.
[0088] For example, if the measured pump pressure is higher than the pump capacity and / or lubrication target allowed based on user input, the calculated motor speed and / or motor torque will decrease, causing the pump pressure to be adjusted to decrease. Conversely, if the measured pump pressure is lower than the pump capacity and / or lubrication target allowed based on user input, the calculated motor speed and / or motor torque will increase, causing the pump pressure to be adjusted to increase. Therefore, the DPU calculates and determines the desired motor speed and / or motor torque, which is not zero.
[0089] The determined desired motor speed and / or motor torque are transmitted from the DPU to the motor controller. This transmission can be continuous or discontinuous. Similarly, the motor controller and motor regulation can be continuous or discontinuous. Preferably, before setting the desired target motor speed and / or motor torque, the motor is operated discontinuously by stopping it for a predetermined amount of time and then restarting it at the new set speed.
[0090] It has been found that a more efficient lubrication process can be achieved by adjusting pump operation based on measured pump pressure relative to a given pump capacity and / or lubrication target.
[0091] Figure 2B Another embodiment of a mobile lubrication pump or dispensing station 9 according to the present disclosure for dispensing lubricant from a grease container 7 to a lubrication target 8 is shown. The system includes a pump 1 connected to a motor (not shown) for driving the pump, and wherein the operation of the motor is regulated by a motor controller 3.
[0092] The motor controller 3 can be a digital or analog controller with a data processing unit (DPU) configured to communicate with the motor controller and to receive input from a pressure monitor 4, which measures pump pressure via a pressure sensor / gauge or via pump parameters that derive the pressure, such as the current flowing in the pump motor. The DPU is also configured to receive user input, for example, via a user interface 6 (such as a potentiometer, button, or touchscreen), where the user input relates to pump capacity and / or lubrication targets.
[0093] Example 2: Mobile lubrication pump with communication device
[0094] Figure 3AAn embodiment of a mobile lubrication pump according to the present disclosure is shown, wherein the user interface includes a wireless communication device, and wherein the DPU optionally includes a computer execution unit. Figure 3A A mobile lubrication pump for dispensing lubricant or grease from container 7 to lubrication target 8 is shown. The system includes a pump 1 connected to a motor 2 for driving the pump, wherein the motor operation is regulated by a motor controller 3. The pump, motor, and motor controller are illustrated as an integrated unit. The pump also includes a pressure monitor 4 for measuring pump pressure by pump parameters that derive the pressure, such as the current flowing in the pump motor.
[0095] The system also includes a data processing unit (DPU) 5, which communicates with the motor controller and receives input from the pressure monitor. The DPU is also configured to receive user input via, for example, a user interface 6 (such as a communication device). Advantageously, the communication device is a wireless device, such as a tablet, smartphone, or laptop computer. Figure 3A As shown. The communication device can receive input from the user via manual input and / or via a tag reader configured to read tags or RFID associated with pump capacity and / or lubrication points. For example, the tag reader could be as follows: Figure 3A The scanning device or RFID reader shown.
[0096] Advantageously, the DPU receives input from a communication device via a near-field coupling receiver, a Bluetooth receiver, and / or an antenna configured to receive signals via the wireless Internet or to receive frequency-banded signals transmitted by a mobile phone.
[0097] Furthermore, the DPU and communication device can be configured to transmit received input to a computer, and advantageously, the transmission is wireless, such as... Figure 3A As shown.
[0098] Different lubrication targets require different amounts of grease to ensure adequate lubrication. Furthermore, different lubrication targets generate different back pressures and back pressure rates. Therefore, the first bearing needs and can withstand high lubricant pressures for effective lubrication, and correspondingly generates high back pressure, while the second bearing can withstand only low lubricant pressures for effective lubrication. To ensure effective and safe lubrication of the targets, the targets can be marked with information on permissible lubrication conditions, such as the maximum permissible lubrication pressure.
[0099] Different pumps have different pump capacities (i.e., different target or optimal capacities) which operate most efficiently to generate the pump pressure used to dispense lubricant. To ensure efficient and safe operation of the pump, pumps are typically labeled with their pump capacity based on their pump type, as described above.
[0100] When using the mobile lubrication pump according to this disclosure, the mobile pump is first moved to the vicinity of the lubrication target. At the lubrication target, a communication device receives information related to the lubrication target, as well as the pump capacity, for example, by the user scanning a tag / RFID associated with the pump and / or the target.
[0101] During pump operation, a pressure monitor monitors any changes in pump pressure. For example, the pressure may gradually increase due to an increase in back pressure. The pressure monitor transmits the monitored pressure to the DPU, and based on the actual measured pressure and inputs related to pump capacity and / or lubrication targets, the DPU can calculate or determine motor speed and / or motor torque, which will adjust the pump pressure.
[0102] For example, if the measured pump pressure is higher than the pump capacity and / or lubrication target allowed based on user input, the calculated motor speed and / or motor torque will decrease, causing the pump pressure to be adjusted to decrease. Conversely, if the measured pump pressure is lower than the pump capacity and / or lubrication target allowed based on user input, the calculated motor speed and / or motor torque will increase, causing the pump pressure to be adjusted to increase. Therefore, the DPU calculates and determines the desired motor speed and / or motor torque, which is not zero.
[0103] The determined desired motor speed and / or motor torque are transmitted from the DPU to the motor controller. This transmission can be continuous or discontinuous. Similarly, the motor controller and motor regulation can be continuous or discontinuous. Preferably, before setting the desired target motor speed and / or motor torque, the motor is operated discontinuously by stopping it for a predetermined amount of time and then restarting it at the new set speed.
[0104] The desired motor speed and / or motor torque can be directly calculated and determined by the DPU. Alternatively, the calculation can be performed on a computer communicating with the DPU and / or communication devices, such as... Figure 3A As shown.
[0105] It has been found that a more efficient lubrication process can be achieved by adjusting pump operation based on measured pump pressure relative to a given pump capacity and / or lubrication target.

Figure 3AA mobile lubrication pump or dispensing station 9 is shown for dispensing lubricant or grease from container 7 to lubrication target 8. The system includes a pump 1 connected to a motor (not shown) for driving the pump, wherein the motor operation is regulated by a motor controller 3, which may be a controller with a data processing unit (DPU) or an analog controller, and is configured to communicate with the motor controller and receive input from a pressure monitor 4, which measures pump pressure via a pressure sensor / gauge or by pump parameters that derive the pressure (e.g., the current flowing in the pump motor). The controller is also configured to receive user input, for example, via a user interface 6, which may be a simple potentiometer, button, touch display, and / or communication device 11, such as a wireless device (e.g., a tablet, smartphone, or laptop).

The communication device can receive input from the user via manual input and / or via a tag reader configured to read tags or RFID associated with pump capacity and / or lubrication points. For example, the tag reader can be a scanning device or an RFID reader, such as... Figure 3B The barcode reader 10 is shown. Advantageously, the controller receives input from the communication device via a near-field coupling receiver, a Bluetooth receiver, and / or an antenna configured to receive signals via the wireless internet or to receive frequency-banded signals transmitted by a mobile phone.
