Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 568,658, filed on March 22, 2024, and U.S. Provisional Application No. 63 / 648,247, filed on May 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to a monitoring system, and in particular to a biological signal monitoring system. More particularly, the present disclosure relates to a biological signal monitoring system comprising a wireless signal acquisition device and a dock. Background Art

[0003] Typically, biosignal monitoring systems include wired signal acquisition devices that require a cable connection to a power source. This cable connection may limit the patient's range of motion and / or hinder the technician's range of motion. Wired signal acquisition devices may require an isolation barrier to electrically isolate the patient from the system, which can increase cost and device size and may require additional safety testing.

[0004] Some biosignal monitoring systems include wireless signal acquisition devices; however, these devices typically include either a primary battery or a replaceable secondary battery. Technicians may need to continually purchase and replace the primary battery. Furthermore, to replace the primary battery, the device may include a battery door, which can be an additional entry point for liquids and hinder cleaning. Therefore, patients and technicians may prefer devices with captive secondary batteries. However, captive secondary batteries may require the wireless signal acquisition device to be connected to a charging power source via a wired cable, which can lead to similar issues as with wired signal acquisition devices. Secondary batteries can be recharged wirelessly using short-range inductive wireless charging protocols such as Qi, the AirFuel Alliance, or similar technologies. However, using Qi in low-power, small-size systems can be costly, may generate excessive heat within the device, and can be inefficient at transmitting small amounts of power to the device. Furthermore, utilizing the Qi protocol may require cross-platform certification testing, and the system may be forced to adapt and operate with external medical or consumer devices not included in the system. Therefore, a wireless signal acquisition device with a customized wireless recharging technology implementation may be beneficial in reducing total solution cost, power transfer efficiency, improving heat dissipation, and incompatibility with consumer-grade charging technologies.

[0102] When the wireless signal acquisition device 12 is positioned in the recess 80 of the docking station 14, the docking station charging unit 86 cooperates with the power receiver 42 of the device charging unit 18 of the wireless signal acquisition device 12 to provide inductive charging of the rechargeable battery 40 of the wireless signal acquisition device 12, such as Figure 1 and Figure 7 As shown in FIG. , the docking station charging unit 86 receives power from the host device 78 via the port 68. When current flows through the docking station charging unit 86, the docking station charging unit 86 generates an electromagnetic field. When the wireless signal acquisition device 12 is positioned in the recess 80 of the docking station 14, a current is induced in the power receiver 42 of the device charging device 18 of the wireless signal acquisition device 12 due to electromagnetic induction. The current received by the power receiver 42 charges the rechargeable battery 40. Alignment of the power receiver 42 of the wireless signal acquisition device 12 with the docking station charging unit 86 of the docking station 14 allows the rechargeable battery 40 to be charged. 40 to charge and / or maximize the charge of the rechargeable battery 40. Therefore, the docking station charging unit 86 of the docking station 14 is positioned on the docking station 14 so that when the wireless signal acquisition device 12 is positioned in the recess 80 of the docking station 14, the docking station charging unit 86 is aligned with the power receiver 42 of the wireless signal acquisition device 12.

[0103] The docking station 14 is formed to include a lead set groove 92, a lead set holding portion 94, and a gripping portion 96. Figure 2 and Figure 7 . A lead set groove 92 is formed in the docking station 14, and when the wireless signal acquisition device 12 is positioned on the docking station 14, the lead set groove 92 provides relief for a portion of the lead set 30 to pass through. In some embodiments, a lead set retaining portion 94 is formed in the body 66 of the docking station 14, and the lead set retaining portion 94 is configured to extend around at least a portion of the lead set 30 when the wireless signal acquisition device 12 is received in the docking station 14 to maintain the position of the lead set 30 relative to the docking station 14. A gripping portion 96 is formed in the docking station 14 to facilitate removal of the wireless signal acquisition device 12 from the docking station 14.

[0104] The lead set groove 92 extends outwardly from the recess 80 of the docking station 14, as shown in FIG. Figure 2 . When the wireless signal acquisition device 12 is positioned in the docking station 14, a portion of the lead set 30 adjacent to the first end 32 of the lead set 30 passes through the lead set groove 92. The lead set groove 92 is formed in the body 66 at an end of the docking station 14 opposite the docking station charging unit 86. When the wireless signal acquisition device 12 is positioned on the docking station 14, the docking station charging unit 86 of the docking station 14 is concentrically aligned with the device charging unit 18 of the wireless signal acquisition device 12, and the lead set 30 of the wireless signal acquisition device 12 is aligned with the lead set groove 92 of the body 66 of the docking station 14.

[0105] In some embodiments, the lead set retaining portion 94 is defined by the second curved portion 76B of the side wall 76 of the docking station 14, as shown in FIG. Figure 7 As shown in . For example, the lead set 30 passes through the lead set groove 92 and is received by the second curved portion 76B. A portion of the lead set 30 is fitted into the concave second curved portion 76B to secure the portion of the lead set 30 to the concave second curved portion 76B. The lead set holding portion 94 provides management for the lead set 30 to reduce tangling of the lead set 30.

[0106] like Figure 1 and Figure 2As shown in FIG, the gripping portion 96 extends outwardly from the recess 80 of the docking station 14 to facilitate gripping the wireless signal acquisition device 12 during removal from the docking station 14. The housing 16 is gripped. In some embodiments, the grip portion 96 includes a first gripping recess 96A and a second gripping recess 96B opposite the first gripping recess 96A. Each of the first gripping recess 96A and the second gripping recess 96B extends outward from the recess 80 and is defined by a concave portion of the front wall 72 of the body 66 of the docking station 14. The patient's or technician's fingers are received in the gripping recesses 96A, 96B, allowing the patient or technician to easily grip the wireless signal acquisition device 12 and remove the wireless signal acquisition device 12 from the recess 80 of the docking station 14.

[0107] The positioning assembly 98 is configured to secure and align the wireless signal acquisition device 12 within the first acquisition device receiving portion 70 (i.e., the recess 80) of the docking station 14 so that the wireless signal acquisition device 12 is removably positioned within the first acquisition device receiving portion 70. The positioning assembly 98 facilitates alignment of the power receiver 42 of the wireless signal acquisition device 12 with the docking station charging unit 86 of the docking station 14, allowing the rechargeable battery 40 to be wirelessly recharged.

[0108] In some embodiments, the positioning assembly 98 magnetically secures the wireless signal acquisition device 12 within the first acquisition device receiving portion 70. The positioning assembly 98 includes a magnet 98A, which may also be referred to as a docking locator 98A, and a ferromagnetic metal component 98B, which may also be referred to as a docking locator 98B. The magnet 98A is coupled to the body 66 of the docking station 14. The ferromagnetic metal component 98B is coupled to the housing 16 of the wireless signal acquisition device 12.

[0109] In some embodiments, magnet 98A is disposed within the body 66 of docking station 14. For example, magnet 98A is disposed within the body 66 below the forward-facing surface 80A of recess 80. Magnet 91A is located at the end of docking station 14 opposite lead set groove 92. The poles of magnet 98A face outward toward wireless signal acquisition device 12, so that when wireless signal acquisition device 12 is positioned near docking station 14, ferromagnetic metal component 98B of wireless signal acquisition device 12 is attracted to the magnetic field of magnet 98A. This magnetic attraction helps ensure that wireless signal acquisition device 12 is properly positioned on docking station 14 for charging and helps maintain wireless signal acquisition device 12 in place during vibration or movement (e.g., if device 12 and docking station 14 are moved while on a cart).

[0110] In some embodiments, the docking station 14 includes a steel shunt that receives the magnet 98A therein. Beyond the forward-facing surface, the steel shunt completely surrounds magnet 98A. The steel shunt helps focus the magnetic field of magnet 98A toward ferromagnetic metal component 98B of wireless signal acquisition device 12, rather than creating a diffuse magnetic field surrounding magnet 98A. Consequently, when a user positions wireless signal acquisition device 12 on docking station 14, wireless signal acquisition device 12 is more securely held in place within docking station 14, and the attractive force between magnet 98A and ferromagnetic metal component 98B is more noticeable to the user.

[0111] In some embodiments, the ferromagnetic metal component 98B is disposed inside the housing 16 of the wireless signal acquisition device 12 (i.e., within the electronic device receiving space 28). For example, the ferromagnetic metal component 98B is disposed inside the housing 16 near the docking station charging unit 86. The ferromagnetic metal component 98B is located at the end of the wireless signal acquisition device 12 opposite the lead set 30.

[0112] In some embodiments, magnet 98A is disposed on the exterior of body 66 of dock 14. For example, magnet 98A is coupled to the exterior of body 66, such as to forward-facing surface 80A of recess 80 or side surface 80B of recess 80.

[0113] In some embodiments, the ferromagnetic metal component 98B is disposed outside the housing 16 of the wireless signal acquisition device 12. For example, the ferromagnetic metal component 98B is coupled to the rear wall 24 of the housing 16 or the side wall 26 of the housing 16.

[0114] In some embodiments, the positioning assembly 98 mechanically secures the wireless signal acquisition device 12 within the first acquisition device receiving portion 70 of the docking station 14. For example, a docking locator, such as a protrusion, coupled to the wireless signal acquisition device 12 cooperates with a docking locator, such as a receiving portion, coupled to the docking station 14, thereby removably positioning the wireless signal acquisition device 12 within the first acquisition device receiving portion 70.

[0115] The positioning assembly 98 also allows the docking station 14 to be arranged in various orientations, such as horizontal or vertical, while ensuring that the wireless signal collection device 12 is securely positioned in the docking station 14 regardless of the orientation of the docking station 14. In some embodiments, the docking station 14 is configured so that when the docking station 14 is in use, the docking station is supported on a horizontal surface. For example, when the docking station 14 is in use, the rear wall 74 of the body 66 of the docking station 14 is supported on a horizontal surface so that the recess 80 of the docking station 14 can be entered and faces the docking station 14. When the docking station 14 is supported on a horizontal surface, the docking station 14 is in a horizontal orientation, and when the wireless signal collection device 12 is positioned in the docking station 14, the wireless signal collection device 12 is in a horizontal orientation.

[0116] In some embodiments, the docking station 14 can be mounted to a rod 15, such as Figure 7 For example, the rear wall 74 of the body 66 of the docking station 14 can be mounted to the pole 15 so that the docking station 14 remains fixed relative to the pole 15. When the docking station 14 is mounted to the pole 15, the docking station 14 is in a vertical orientation, and when the wireless signal collection device 12 is positioned in the docking station 14, the wireless signal collection device 12 is in a vertical orientation.

[0117] In some embodiments, the docking station 14 can be mounted to a wall in a fixed position. For example, the rear wall 74 of the body 66 of the docking station 14 can be mounted to the wall so that the docking station 14 remains fixed relative to the wall. When the docking station 14 is mounted to the wall, the docking station 14 is in a vertical orientation. When the docking station 14 is mounted to the wall, the forward surface 80A of the recess 80 is parallel to the wall.

In some embodiments, magnet 798A may be omitted.

Except where the description of the docking station 14 conflicts with the specific description and drawings of the docking station 814, the description of the docking station 14 is incorporated by reference to apply to the docking station 814. The docking station 814 includes a body 866, a port 868, and a first acquisition device receiving portion 870.

Figure 20 The bottom end portion 880B is partially closed, so that the bottom end portion 880B supports the wireless signal collection device 412 in the cavity 880, thereby preventing the wireless signal collection device 412 from falling from the bottom end portion 880B.

[0146] Similar to the docking station 14, the docking station 814 includes a docking station communication module, a docking station pairing module, and a docking station charging unit 886. The docking station charging unit 886 is positioned in the body 866 near the top open end 880A of the cavity 880, so that when the wireless signal acquisition device 412 is inserted into the cavity 880, the docking station charging unit 886 of the docking station 814 is aligned with the device charging unit of the wireless signal acquisition device 412.

[0147] In some embodiments, as Figure 20 As shown in FIG, docking station 814 can be mounted to a wall in a fixed position. For example, rear wall 874 of body 866 of docking station 814 can be mounted to a wall so that docking station 814 remains fixed relative to the wall. When docking station 814 is mounted to the wall, docking station 814 is in a vertical orientation.

The lead set extends in a partially extended manner to maintain the position of the lead set relative to the docking station 814. When the wireless signal acquisition device 412 is positioned in the docking station 814, a portion of the lead set passes through the lead set groove 892.

[0149] The magnet 898A of the positioning assembly is located near the top open end of the cavity 880, as shown in FIG. Figure 20 . The magnet 898A is positioned near the top open end 880A of the cavity 880 such that when the wireless signal acquisition device 412 is disposed in the cavity 880, the magnet 898A aligns with a ferromagnetic metal component positioned on or within the wireless signal acquisition device 412. In some embodiments, the magnet 898A can be omitted from the docking station 814.

Dock 814′ includes a body 866′, a port 868′, a first acquisition device receiving portion 870A′, a second acquisition device receiving portion 870B′, and a third acquisition device receiving portion 870C′. Acquisition device receiving portions 870A′, 870B′, and 870C′ are formed in body 866′ to receive wireless signal acquisition device 412 in acquisition device receiving portions 870A′, 870B′, and 870C′.

The front shelf wall 875' is spaced apart from the front wall 872'. The top shelf wall 876' extends outwardly away from the front wall 872' to connect to the front shelf wall 875'. The receiving portions 870A', 870B', 870C' for the acquisition device extend downward from the top shelf wall 876' into the body 866'. The wireless signal acquisition device 412 is inserted into the receiving portions 870A', 870B', 870C' for the acquisition device, as shown in Figure 21 As shown in .

[0152] Wireless signal acquisition device 12, 12', 12", 212, 212', 312, 312', 412, 412', 512, 612 include the first printed circuit board assembly 102 and the second printed circuit board assembly 104 positioned in the housing 16, 16', 16", 216, 216', 316, 316', 416, 416', 516, 616, as shown. Figure 22 Although Figures 22 to 31B The wireless signal collection device 12 and the docking station 14 are shown and described, but Figures 22 to 31B The corresponding descriptions also apply to the wireless signal acquisition devices 12 ′, 12 ″, 212 , 212 ′, 312 , 312 ′, 412 , 412 ′, 512 , 612 and the docking stations 714 , 814 .

[0153] Each of the board assemblies 102, 104 is coupled to the housing 16. The first printed circuit board assembly 102 is coupled to the front wall 22, such as via screws, and the second printed circuit board assembly 104 is coupled to the rear wall 24, such as via screws. The first printed circuit board assembly 102 is disposed between the front wall 22 of the housing 16 and the second printed circuit board assembly 104, while the second printed circuit board assembly 104 is disposed between the first printed circuit board assembly 102 and the rear wall 24 of the housing 16.

[0154] The first PCB assembly 102 is connected to the buttons 50, 52 and the bio-signal status indicators 56, 58, as shown in FIG. Figure 22 As shown in FIG. 4 , the rechargeable battery 40 is arranged below the first printed circuit board assembly 102 and in front of the second printed circuit board assembly 104. Figure 22 The rechargeable battery 40 is coupled to the first printed circuit board assembly 102 via the battery connector 108, as shown in FIG. Figure 24 In some embodiments, the rechargeable battery 40 is positioned in a foam-lined chamber 114, as shown in FIG. Figure 22 The board-to-board interconnect 106 extends between the first PCB assembly 102 and the second PCB assembly 104 and connects the first PCB assembly 102 and the second PCB assembly 104 to each other.

[0155] The second PCB assembly 104 includes a collection circuit 120, such as Figure 25 As shown in . Acquisition circuit 120 acquires biological signals from a patient via lead set 30 and digitizes the biological signals. Lead set connector 36 provides a standard interface for lead sets 30 having different numbers of channels and one or more identification features. Acquisition circuit 120 detects the number of channels of lead set 30 and adjusts the performance of device 12 accordingly. In some embodiments, acquisition circuit 120 is shielded by a shielding cover.

[0156] like Figure 22As shown in FIG, the wireless signal collection device 12 has a thickness T defined between the front wall 22 of the housing 16 and the rear wall 24 of the housing 16. The thickness T of the device 12 is about 20 mm to about 30 mm. In some embodiments, the thickness T of the device 12 is about 25 mm. In some embodiments, the thickness T of the device 12 is not greater than about 25 mm. The wireless signal collection device 12 has a width W1, such as Figure 25 In some embodiments, the width W1 of the device 12 is about 40 mm to about 50 mm. In some embodiments, the width W1 of the device 12 is about 42 mm. In some embodiments, the width W1 of the device 12 is no greater than about 50 mm. The thickness T and width W1 of the device 12 allow the device 12 to be handheld.

[0157] like Figure 25 and Figure 31B As shown in FIG, the wireless signal acquisition device 12 includes a device communication module 20, a device pairing module 48, and a device charging unit 18. The docking station 14 includes a docking station communication module 82, a docking station pairing module 84, and a docking station charging unit 86. Figure 26 and Figure 31A As shown in .

[0158] The device communication module 20 and the docking station communication module 82 allow data exchange between the device 12 and the host device 78, which has a real-time (with a certain margin) wireless link and a high sampling rate buffer for transmitting time-accurate data. In some embodiments, the device communication module 20 and / or the docking station communication module 82 include a Bluetooth Low Energy ("BLE") 5.2 / 5.3+ module. Bluetooth Low Energy allows for synchronous channel communication and encryption mechanisms.

[0159] In some embodiments, the device communication module 20 includes a dual-core Bluetooth low energy module that collects and processes biosignal data while maintaining a wireless connection with the docking station 14. The dual-core design enables one of the cores (i.e., the wireless data transmitter 44 of the device communication module 20) to communicate wirelessly with the docking station 14, while the other core (i.e., the wireless data receiver 46 of the device communication module 20) runs firmware that collects oversampled biosignal data from the acquisition circuit 120, extracts the data, filters the data, feeds the data through an algorithm, and then transmits the data to the wireless communication core (i.e., the wireless data transmitter 44). The wireless communication core (i.e., the wireless data transmitter 44) utilizes the real-time audio capability of BLE to transmit the data to the docking station communication module 82 at determined intervals. Figure 25 As shown in FIG, the device communication module 20 is located on the second PCB assembly 104 .

[0160] In some embodiments, the docking station communication module 82 includes a Bluetooth low energy module that receives the biosignal data and the electrical signal from the wireless data transmitter 44 of the device communication module 20. Force feedback data, such as Figure 31A and Figure 31B The docking station communication module 82 is located on the third printed circuit board assembly 140 of the docking station 14, as shown in FIG. Figure 26 In some embodiments, the device communication module 20 and / or the docking station communication module 82 includes Wi-Fi support configured to transmit the biosignal data to a Wi-Fi enabled display system, such as a PC, mobile phone, or tablet computer, via the hospital network.

[0161] The device pairing module 48 and the dock pairing module 84 are configured to implement a protocol implementation to prevent cross-compatibility between the device 12 and consumer market devices. In some embodiments, the device pairing module 48 includes a device NFC chip 85, while the dock pairing module 84 includes a dock NFC chip 87. In such embodiments, the device NFC chip 85 functions as an NFC tag, while the dock NFC chip 87 functions as an NFC reader. The NFC link between the pairing modules 48 and 84 transmits loop feedback to the dock 14. The NFC chips 85 and 87 enable secure out-of-band exchange of secrets and pairing / binding of the device 12 and the dock 14. Even though the biosignal data transmitted between the device 12 and the dock 14 may be anonymous, the pairing modules 48 and 84 enable secure pairing of the device 12 and the dock 14. The wireless link between the communication modules 20 and 82 for communication between the communication modules 20 and 82 is established via out-of-band pairing with the pairing modules 48 and 84. Out-of-band pairing establishes a secure pairing between the device 12 and the dock 84. Pairing modules 48, 84 can be used to securely transmit credentials for secure pairing. Compared to Bluetooth pairing, pairing modules 48, 84 can provide benefits such as speed, simplicity, and reduced cost. For example, pairing modules 48, 84 do not require user input to pair with each other, and pairing modules 48, 84 incorporate additional security benefits.

[0162] In some embodiments, the device pairing module 48 includes an NFC tag coil 136, such as Figure 25 and Figure 31B . The NFC tag coil 136 is illustratively formed as a printed coil located on the second printed circuit board assembly 104 above the power receiver 42. In some embodiments, the docking station pairing module 84 includes an NFC reader coil 138, such as Figure 26 and Figure 31BAs shown. The NFC reader coil 138 is illustratively formed as a printed coil located on the third printed circuit board assembly 140 of the docking station 14, above the docking station charging unit 86. The NFC reader 87 passes current through the NFC reader coil 138, thereby generating a magnetic field. When the NFC tag 85 and the NFC tag coil 136 are close to the NFC When the device 12 is connected to the dock 14 and the NFC reader coil 138, the magnetic field induces a current in the NFC tag coil 136. The NFC tag coil 136 and the NFC reader coil 138 allow pairing and, therefore, wireless communication between the device 12 and the dock 14.

[0163] Illustratively, the pairing modules 48, 84 are enabled only when the device 12 is positioned in the dock 14, to pair the device 12 and the dock 14 and form a wireless link between the device 12 and the dock 14. In response to the device 12 being positioned in the dock 14, the device 12 and the dock 14 automatically pair with each other. After the device 12 and the dock 14 are paired, the wireless link between the device 12 and the dock 14 is automatically established, and wireless power transfer from the dock 14 to the device 12 is automatically initiated.

[0164] The docking station 14 senses when the device 12 is positioned on the docking station 14 so that the docking station 14 and the device 12 can be paired. Figure 26As shown in FIG, a third printed circuit board assembly 140 of the docking station 14 includes two unterminated conductors 142, 144, such as two capacitor plate electrodes, and a low-power capacitance monitoring circuit 146. The two unterminated conductors 142, 144 are, for example, two capacitor plate electrodes. The low-power capacitance monitoring circuit 146 is configured to detect a change in capacitance between the capacitor plate electrodes 142, 144 when the docking station 14 is not activated. The docking station 14 remains inactivated to conserve power until the device 12 is positioned on the docking station 14. The low-power capacitance monitoring circuit 146 is configured to apply a switching waveform to one of the capacitor plate electrodes 142, 144. The low-power capacitance monitoring circuit 146 senses the amount of charge that appears on one of the capacitor plate electrodes 142, 144 due to stimulating the other capacitor plate electrode. When the low-power capacitance monitoring circuit 146 detects a change in capacitance between the capacitive plate electrodes 142, 144, the low-power capacitance monitoring circuit 146 wakes up the dock 14 (i.e., the dock communication module 82, the dock charging unit 86, and the dock pairing module 84). In response to the device 12 being positioned on the dock 14, the device 12 appears to the dock 14 (specifically, the low-power capacitance monitoring circuit 146 of the dock 14) as a large conductive object, and the device 12 changes the capacitance between the capacitive plate electrodes 142, 144. The low-power capacitance monitoring circuit 146 senses the change in capacitance and wakes up the dock 14. Upon waking up, the dock 14 automatically provides an initial minimum power level to the device 12 and initiates the pairing process.

[0165] As previously described, the docking station charging unit 86 recharges the rechargeable battery 40 of the device charging unit 18 of the device 12 wirelessly by inductive charging. The second printed circuit board assembly 104 of the device 12 includes the power receiver 42 of the device charging unit 18 located on the second printed circuit board assembly 104, as shown in FIG. Figure 25 As shown in FIG. Illustratively, the power receiver 42 includes a receiver coil 110, such as Figure 27 In some embodiments, the device 12 includes a ferrite plate 122 disposed between the rechargeable battery 40 and the receiver coil 110, as shown in FIG. Figure 22 The ferrite plate 122 is configured to shield the device 12 from induced magnetic fields and to concentrate the magnetic fields to improve coupling of the transmitter coil 154 to the receiver coil 110 .

[0166] The receiver coil 110 is formed to include a plurality of helical layers 116, such as Figure 29In the illustrated embodiment, the receiver coil 110 includes six helical layers 116. In some embodiments, the receiver coil 110 includes between four and ten helical layers 116. Each of the helical layers 116 is stacked relative to each other, and each of the helical layers 116 is equidistant from the central axis C1 of the receiver coil 110, as shown in FIG. Figure 29 . In other words, for each of the plurality of helical layers 116, the outer diameter D1 of each of the plurality of helical layers 116 is the same. As an example, in some embodiments, the outer diameter D1 of each of the plurality of helical layers 116 is about 40 mm. In some embodiments, the outer diameter D1 of each of the plurality of helical layers 116 is about 35 mm to about 45 mm. In some embodiments, the outer diameter D1 of each of the plurality of helical layers 116 is about 25 mm to about 55 mm. Each of the plurality of helical layers 116 extends circumferentially around the central axis C1. Each of the plurality of helical layers 116 is separated from each other.

[0167] Each of the plurality of spiral layers 116 is made of a flat copper sheet having a rectangular cross-sectional shape (as opposed to a coil having a circular cross-sectional shape). The width W2 of each of the plurality of spiral layers 116 is relatively wide. For example, in some embodiments, the width W2 of each of the plurality of spiral layers 116 is approximately 5 mm. In some embodiments, the width W2 of each of the plurality of spiral layers 116 is between 4 mm and 6 mm. In some embodiments, the width W2 of each of the plurality of spiral layers 116 is between approximately 3 mm and approximately 7 mm. Illustratively, the receiver coil 110 is a printed circuit board receiver coil 110.

[0168] The receiver coil 110 includes a plurality of vias 152 (ie, vertical interconnecting channels), such as Figure 29 . The plurality of vias 152 extend between the plurality of spiral layers 116 and interconnect the plurality of spiral layers 116. The plurality of vias 152 are configured to transmit signals between each of the plurality of spiral layers 116 of the receiver coil 110 and allow electrical connections between each of the plurality of spiral layers 116 within the printed circuit board receiver coil 110.

[0169] The second PCB assembly 104 includes a plurality of capacitors 148, a rectifier 118, and a power management and monitoring subsystem 150, such as Figure 31B. Capacitor 148 transfers the AC current from the receiver coil 110 to the rectifier 118. The capacitor 148 and the receiver coil 110 are arranged in a parallel configuration. The parallel LC circuit configuration allows for a lower voltage on the receiver coil 110 and a higher current to pass through the receiver coil 110.

[0170] The rectifier 118 is configured to convert alternating current to direct current. In some embodiments, the rectifier 118 is a Schottky bridge rectifier. Compared to other rectifiers, a Schottky bridge rectifier has a lower voltage drop, thereby reducing power loss and heat generation. The power management and monitoring subsystem 150 includes an input power protection device that is configured to short-circuit the receiver coil 110 in the event of an overvoltage condition. In some embodiments, the power management and monitoring subsystem 150 includes a high-efficiency, high-input voltage buck converter that is configured to provide a low-voltage system rail for charging the rechargeable battery 40. In some embodiments, the power management and monitoring subsystem 150 includes power path processing circuitry that is configured to select power from the rechargeable battery 40 or power input to the receiver coil 110 as input to downstream circuitry. In some embodiments, the power management and monitoring subsystem 150 includes a buck-boost converter configured to step up or step down the voltage of the rechargeable battery 40 or input voltage into a clean digital power rail to power downstream circuits. In some embodiments, the power management and monitoring subsystem 150 includes voltage sensing circuitry for the input receiver coil 110, voltage sensing circuitry for the rechargeable battery 40, and current consumption sensing circuitry for the device 12.

[0171] Figure 27 and Figure 28 An exemplary circuit for device 12 is shown in FIG. Figure 27 and Figure 28 Actually This is exemplary and represents only one embodiment of circuitry that may be used to control device 12. It should be understood that any of a variety of other circuits may be used to perform the described control of device 12.

[0172] In some embodiments, the rechargeable battery 40 is at least a 3.7Wh battery. For example, the rechargeable battery 40 may include a 1000mAh 1S1P lithium-ion polymer battery. Power feedback data may be transmitted and / or exchanged with the docking station charging unit 86. For example, the device communication module 20 may communicate with the docking station communication module 82 and / or the docking station charging unit 86 to notify the receiver coil 110 of the power receiver 42 that it is receiving too much or too little power. In some embodiments, the rechargeable battery 40 allows for approximately 14 hours of continuous biosignal data collection upon first use. In some embodiments, the rechargeable battery 40 allows for approximately 8 hours of continuous biosignal data collection when fully charged. In some embodiments, the rechargeable battery 40 allows for approximately 1 hour of continuous biosignal data collection after 15 minutes of charging. In some embodiments, the rechargeable battery 40 allows for approximately 4 hours of continuous biosignal data collection after one hour of charging. In some embodiments, the rechargeable battery 40 allows for approximately 8 hours of continuous biosignal data collection at the end of the rechargeable battery 40's service life. In some embodiments, the rechargeable battery 40 is charged from zero to full charge in approximately 3.5 hours.

[0173] The third printed circuit board assembly 140 of the docking station 14 includes the docking station charging unit 86, such as Figure 26 and Figure 28 As shown in FIG. Illustratively, the docking station charging unit 86 includes a transmitter coil 154, such as Figure 30 . The transmitter coil 154 of the docking station charging unit 86 receives power from the host device 78 via the port 68. For example, the transmitter coil 154 is powered by the USB 2.0 bus. When current flows through the transmitter coil 154, the transmitter coil 154 generates an electromagnetic field. When the wireless signal acquisition device 12 is positioned in the recess 80 of the docking station 14, a current is induced in the receiver coil 110 of the power receiver 42 of the device charging unit 18 of the wireless signal acquisition device 12 due to electromagnetic induction. The current received by the receiver coil 110 charges the rechargeable battery 40. The concentric alignment of the receiver coil 110 of the wireless signal acquisition device 12 and the transmitter coil 154 of the docking station charging unit 86 allows the rechargeable battery 40 to be charged and / or the charging of the rechargeable battery 40 to be maximized. Therefore, the transmitter coil 154 of the docking station charging unit 86 is positioned on the docking station 14 so that when the wireless signal acquisition device 12 is positioned in the recess 80 of the docking station 14, the transmitter coil 154 is concentrically aligned with the receiver coil 110 of the power receiver 42 of the wireless signal acquisition device 12. Furthermore, the positioning assembly 98 magnetically aligns the wireless signal acquisition device 12 within the first acquisition device receiving portion 70 of the docking station 14 so that the receiver coil 110 of the power receiver 42 and the transmitter coil 154 of the docking station charging unit 86 are concentrically aligned, thereby wirelessly recharging the rechargeable battery 40. Due to the wireless charging of the rechargeable battery 40, no electrical connection is formed to the external environment, thereby achieving a 2xMOPP patient isolation barrier by isolating the CF application-type component from any other systems via the housing 16.

[0174] The transmitter coil 154 is constructed similarly to the receiver coil 110, such as Figure 29 and Figure 30 . The transmitter coil 154 is formed to include a plurality of helical layers 156. In the illustrated embodiment, the transmitter coil 154 includes six helical layers 156. In some embodiments, the transmitter coil 154 includes between four and ten helical layers 156. Each of the helical layers 156 is stacked relative to one another, and each of the helical layers 156 is equidistant from the central axis C2 of the transmitter coil 154, as shown. Figure 30 . In other words, for each of the plurality of helical layers 156, the outer diameter D2 of each of the plurality of helical layers 156 is the same. As an example, the outer diameter D2 of each of the plurality of helical layers 156 is about 40 mm. In some embodiments, the outer diameter D2 of each of the plurality of helical layers 156 is about 35 mm to about 45 mm. In some embodiments, the outer diameter D2 of each of the plurality of helical layers 156 is about 25 mm to about 55 mm. Each of the plurality of helical layers 156 extends circumferentially around the central axis C2. Each of the plurality of helical layers 156 is separated from each other.

[0175] Each of the plurality of helical layers 156 is made of a flat copper sheet having a rectangular cross-sectional shape (as opposed to a coil having a circular cross-sectional shape). The width W3 of each of the plurality of helical layers 156 is relatively wide. For example, in some embodiments, the width W3 of each of the plurality of helical layers 156 is about 5 mm. In some embodiments, Each helical layer in the plurality of helical layers 156 has a width W3 of about 4 mm to about 6 mm. In some embodiments, each helical layer in the plurality of helical layers 156 has a width W3 of about 3 mm to about 7 mm. Illustratively, the transmitter coil 154 is a printed circuit board transmitter coil 154 .

[0176] The transmitter coil 154 includes a plurality of vias 158 (ie, vertical interconnect channels), such as Figure 30 . The plurality of vias 158 extend between the plurality of spiral layers 156 and interconnect the plurality of spiral layers 156. The plurality of vias 158 are configured to transmit signals between each of the plurality of spiral layers 156 of the transmitter coil 154 and allow electrical connections between each of the plurality of spiral layers 156 within the printed circuit board transmitter coil 154.

[0177] like Figure 31A As shown in FIG, the transmitter coil 154 of the docking station charging unit 86 is connected to a power source (i.e., connected to the host device 78 via the port 68). When current flows through the transmitter coil 154, the transmitter coil 154 generates an electromagnetic field around the transmitter coil 154. When the receiver coil 110 of the power receiver 42 is placed near the electromagnetic field of the transmitter coil 154 of the docking station charging unit 86, a current is induced in the receiver coil 110 of the power receiver 42 due to electromagnetic induction. The induced current in the receiver coil 110 of the power receiver 42 is an alternating current. The alternating current is converted to a direct current using a rectifier 118, as shown in FIG. Figure 31B The converted DC current is then used to charge the rechargeable battery 40.

[0178] Illustratively, the transmitter coil 154 is configured to transfer a maximum of approximately 1.5 W of power to the receiver coil 110 of the power receiver 42 while maintaining a low internal ambient temperature of the dock 14 and the device 12. The internal ambient temperature of the device 12 and / or dock 14 does not rise by more than approximately 10° C. during wireless power transfer. In some embodiments, the internal ambient temperature of the device 12 and / or dock 14 does not rise by more than approximately 6° C. during wireless power transfer. The relatively low heat generated when transferring up to 1.5 W of power to the receiver coil 110 allows sensitive components to be placed in close proximity to the receiver coil 110 without posing a risk to these sensitive accessories.

[0179] Each of the multiple helical layers 116, 156 of the coils 110, 154 is relatively wide to reduce DC and AC resistance effects. The charging unit 18, 86 utilizes an air core transformer topology as a power receiving coil between the transmitter coil 154 of the docking charging unit 86 and the device charging unit 18. The transmitter coil 154 is a device that transfers energy between the receiver coil 110 and the power receiver 42. The magnetic field generated by the transmitter coil 154 penetrates the receiver coil 110 through the air gap (the gap between the dock 14 and the device 12). For example, the distance between the coils 110 and 154 can be approximately 6 mm to approximately 7 mm. The changing magnetic field induces a current in the receiver coil 110 of the power receiver 42, which generates a voltage across the receiving load to power the device 12. In some embodiments, each of the coils 110 and 154 is made of 0.5 oz copper.

[0180] The shape and design of coils 110 and 154 account for the skin effect and proximity effect common to conventional coils. The skin effect refers to the tendency of current within a conductor to become distributed so that the current density is greatest near the conductor's surface (i.e., the skin). High-frequency currents exhibit a more pronounced skin effect. Since the skin effect is more pronounced at higher frequencies, it is less of a concern at the frequencies of coils 110 and 154.

[0181] The proximity effect occurs when two or more conductors are placed in close proximity and their electromagnetic fields interact, redistributing the current in each of the conductors, thereby concentrating the current density in the portion of the conductor farthest from the intervening conductor. In other words, a higher current density exists in the winding of the conductor closest to the core, increasing the AC resistance of the coil. The proximity effect can affect multiple layers of winding around a central core (i.e., windings that are each further away from the central core). Winding the coils 110, 154 into a single helical layer, such that each of the multiple helical layers 116, 156 is equidistant from the central axis C1, C2, evenly distributes the current across each of the multiple helical layers 116, 156 and eliminates at least some of the effects of the proximity effect. The relatively large surface area (i.e., width W, W3) of each of the multiple helical layers 116, 156 also aids in current distribution.

[0182] Increasing the inductance of coils 110, 154 can increase the efficiency of power transfer between coils 110, 154. Inductance can be increased by increasing the size of the effective loop area of ​​each of the plurality of helical layers 116, 156 or by increasing the number of turns of coils 110, 154 (i.e., the number of helical layers 116, 156). However, increasing the number of helical layers 116, 156 in coils 110, 154 increases the length of each coil 110, 154, thereby increasing the DC resistance of coils 110, 154. The illustrative six helical layers 116, 156 allow each of the plurality of helical layers 116, 154 to be as wide as possible (widths W2, W3).

[0183] The third PCB assembly 140 includes a plurality of capacitors 162, a boost regulator and transmitter subsystem 164, and a power management and monitoring subsystem 166, as shown in FIG. Figure 26 and Figure 31A As shown in , capacitor 162 and transmitter coil 154 are arranged in a series configuration. In this series configuration, the Q factor, which represents efficiency, is proportional to frequency. Higher frequencies increase the Q factor, and power transfer efficiency increases. As previously mentioned, at higher frequencies, skin and proximity effects can become excessive. In some embodiments, the target drive frequency is approximately 1 MHz to 2 MHz. At these frequencies, skin effect is not a concern given the relatively small thickness of each of the plurality of helical layers 116, 156.

[0184] The boost regulator and transmitter subsystem 164 is configured to boost input power to a configurable higher voltage to power the docking station charging unit 86. In some embodiments, the boost regulator and transmitter subsystem 164 comprises a MOSFET H-bridge driven by a synchronous half-bridge gate driver. The H-bridge drives a series LC resonant circuit formed by capacitor 162 and transmitter coil 154. In some embodiments, the driving voltage of the boost regulator and transmitter subsystem 164 is between approximately 5.5V and approximately 8V. The power management and monitoring subsystem 166 provides: input power protection and filtering; stepping down the input voltage to provide power to the boost regulator and transmitter subsystem 164; and sensing the input current so that the docking station 14 limits the current drawn from the host device 78 via the port 68. The power management and monitoring subsystem 166 includes, for example, an overpower protector and / or an overcurrent protector.

It should be understood that any of a number of other circuits may be used to perform the described control of the dock 14.

In some embodiments, the device 12 includes an accelerometer 126 and / or an inertial measurement unit 128 disposed within the device 12, such as Figure 31B The accelerometer 126 is configured as shown in FIG. The acceleration of device 12 is measured. For example, the measured acceleration of device 12 may indicate that device 12 has been lifted from a surface (i.e., removed from dock 14). In some embodiments, the measured acceleration of device 12 may be used to determine when to wake device 12.

[0187] In some embodiments, the device 12 includes an audio unit 130 and / or a buzzer 132, such as Figure 31B . The audio unit 130 and / or the buzzer 132 are configured to generate sounds. For example, the audio unit 130 and / or the buzzer 132 may generate sounds to serve as an audible indicator, such as a warning. For example, if the temperature sensor 124 detects that the internal temperature of the device 12 is too high, the audio unit 130 and / or the buzzer 132 may generate a sound. As another example, the audio unit 130 and / or the buzzer 132 may generate a sound when the charge level of the rechargeable battery 40 is low.
