Modified Fig. 6a of Solomko (U.S. Pub. No. 2016/0266185 A1)
Regarding Claim 1, Xue teaches a hearing device (hearing device 100A and 100B, Figs. 1D and 1E, Para. [0070]) comprising:
an antenna (antenna 106a, 106b, and 810, Figs. 1D, 1E, and 8, Paras. [0074] and [115]);
a transmission line (transmission line 805, Fig. 8, Para. [0115]);
a wireless communication unit (wireless transceiver 104a, 104b, and TX, Figs. 1D, 1E and 8, Paras. [0074] and [115]), the wireless communication unit being coupled to the antenna via the transmission line (wireless transceiver 104a, 104b, and TX, is connected to antenna via transmission line 805, Fig. 8, Para. [0115]), the wireless communication unit and the antenna are configured for signal transmission and signal reception (wireless transceiver [TX, RX] and antenna 810 are configured for signal transmission [transmit channel 801] and signal reception [receive channel 803], Fig. 8, Paras. [0115] and [0116]).
Xue fails to explicitly teach a conductor element;
a detector coupled to the conductor element and configured to detect a reflected power signal via the conductor element, the reflected power signal indicating an amount of power reflected towards the wireless communication unit from the antenna, wherein the conductor element is galvanically isolated from the transmission line; and
a processing unit configured to place the hearing device in an idle mode if the reflected power signal indicates that the amount of power reflected meets a criterion;
wherein the detector is configured to detect the reflected power signal as a function of frequency and time.
However, Solomko teaches a conductor element (reflection measuring circuit show conductor element within directional coupler 1, 620, Fig. 1d, Para. [0028]; see modified Fig. 6a);
a detector coupled to the conductor element (power detectors 11, 12, 626, 627 connected to conductor element, Fig. 1d, Paras. [0028] and [0047], see modified Fig. 6a) and configured to detect a reflected power signal via the conductor element, the reflected power signal indicating an amount of power reflected towards the wireless communication unit from the antenna (the directional coupler is used in RF circuits to measure incident or reflected power, Paras. [0016] and [0018]; the reflection measuring circuit of Fig. 1d shows the power detectors 11 and 12 for detecting the reflected antenna power back towards the wireless communication unit 625, Para. [0050]), wherein the conductor element is galvanically isolated from the transmission line (reflection measuring circuit show conductor element galvanically isolated from the transmission line, Fig. 1d and modified Fig. 6a); and
wherein the detector is configured to detect the reflected power signal as a function of frequency and time (information about the amplitude and phase of current and voltage of the RF signal is extracted and compared with a predefined value, such as, but not limited to a 50 Ω impedance. The relationship between the extracted amplitudes and phases of the RF current and voltage indicates the amount of reflection in the RF signal path and therefore indicates the load impedance, Para. [0018]; by continuously processing these signals against the predefined baseline (e.g., a 50 Ω impedance), the detector actively calculates the magnitude and phase of the reflection coefficient, effectively monitoring how the system's impedance behaves over time and across frequencies).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue) to include the conductor element galvanically isolated from the transmission line and detector to detect reflected power signal as a function of frequency and time from the antenna back to wireless communication unit (as taught by Solomko). Doing so provides real-time information on wireless connection efficiency allowing for dynamic adjustment of output power.
However, Anderson teaches a processing unit (detection and control circuit 18 which turns on the foil sensor 1 [i.e. the proximity sensor], Para. [0026]) configured to place the device in an idle mode if the reflected power signal indicates that the amount of power reflected meets a criterion (the proximity sensor can be placed in a standby mode [idle mode] when the main electromagnetic signal is being properly transmitted or received again i.e. when the reflected power at a third port of the directional coupler falls below a set threshold, Para. [0026]; reflected power at the third port is reflected power transmitted from the antenna along the directional coupler 4 back to wireless communication unit 2, Paras. [0025]-[0027]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue in view of Solomko) to include the placing the hearing device in idle mode when the reflected power meets a criterion (as taught by Anderson). Doing so will conserve battery power and extend the battery life of the hearing device.
Regarding Claim 5, Xue in view of Solomko, and further in view of Anderson teach wherein the wireless communication unit (Solomko, transmit module 625, Fig. 6a, Para. [0047]) and the antenna (Solomko, antenna 624, Fig. 6a, Para. [0047]) are coupled to each other via at least one microwave coupler that comprises the transmission line (Solomko, microwave coupler 620, Fig. 6a, Para. [0047]), the at least one microwave coupler being configured to couple power reflected from the antenna towards the wireless communication unit to the detector (Solomko, microwave coupler 620 couples reflected power from the antenna to the detectors 626, 627, Fig. 6a, Para. [0047]), and wherein the detector is configured to detect the coupled power from the at least one microwave coupler as the detected reflected power signal (Solomko, directional coupler is used in RF circuits to measure incident or reflected power, Paras. [0016] and [0018]).
Regarding Claim 6, Xue in view of Solomko, and further in view of Anderson teach wherein the transmission line is a part of a microwave coupler coupling the wireless communication unit and the antenna (Solomko, transmission line between wireless communication unit 625 and antenna 624 is part of the microwave coupler 620, Fig. 6a).
Regarding Claim 7, Xue in view of Solomko, and further in view of Anderson teach wherein the hearing device is in a first state when the hearing device is not worn in its operational position in or at an ear of a user (Xue, collected 2-D RSSI data can be used to detect if one of the wearer's two hearing devices falls off the wearer's head, Para. [0085]), and wherein the hearing device is in a second state when the hearing device is worn in its operational position in or at the ear of the user (Xue, collected 2-D RSSI data can be used to detect if one of the wearer's two hearing devices falls off the wearer's head, Para. [0085]). This also means it can be used to determine that the hearing device is worn in its operational position in or at the ear of the user. In Para. [0040] ear-worn device with wireless transceiver coupled to an antenna can collect two-dimensional (2-D) RSSI data, detect input gesture using the 2-D RSSI data, and implement a predetermined function of the ear-worn electronic device in response to detecting input gesture).
Regarding Claim 8, Xue in view of Solomko, and further in view of Anderson teach wherein the hearing device is configured to be operated in the idle mode (Anderson, once the proximity sensor has been turned on then it may continue to operate and provide a continuous or pulsed transmit signal continually or at timed intervals until the proximity sensor detects that the blocking object is no longer present (e.g. until the magnitude of the reflected power at the third port of the directional coupler falls below a set thresh old). The proximity sensor can also be turned off or placed in a standby mode after a predetermined amount of time has lapsed or if the associated detection circuit detects that the main electromagnetic signal is being properly transmitted or received again, for example, Para. [0012]) when the hearing device is in the first state (Xue, collected 2-D RSSI data can be used to detect if one of the wearer's two hearing devices falls off the wearer's head, Para. [0085]), and wherein the hearing device is configured to be operated in one of a number of operational modes when the hearing device is in the second state (Xue, collected 2-D RSSI data can be used to detect if one of the wearer's two hearing devices falls off the wearer's head, Para. [0085]). This also means it can be used to determine that the hearing device is worn in its operational position in or at the ear of the user. In Para. [0040] ear-worn device with wireless transceiver coupled to an antenna can collect two-dimensional (2-D) RSSI data, detect input gesture using the 2-D RSSI data, and implement a predetermined function of the ear-worn electronic device in response to detecting input gesture).
Regarding Claim 9, Xue in view of Solomko, and further in view of Anderson teach wherein the reflected power signal indicating the amount of power reflected towards the wireless communication unit corresponds to a reflection coefficient of the antenna (Solomko, the amount of reflection in the RF signal path indicates the load [antenna] impedance ZL. The equation for the load impedance is shown as ZL = Z0 (1 + Γ0 / 1 - Γ0), where Γ0 represents the reflection coefficient, Para. [0018]; the reflected power will correspond to the reflection coefficient of the antenna).
Regarding Claim 11, Xue in view of Solomko, and further in view of Anderson teach further comprising a memory configured to store the reflected power signal and other reflected power signals as a function of frequency and time (Xue, control circuitry 822 can store reflection coefficient data and can implement an algorithm that monitors the forward and reflected power of the antenna 810, Fig. 8, Para. [0118]; Solomko, reflected power are detected as a function of frequency and time, Para. [0018]).
Regarding Claim 12, Xue in view of Solomko, and further in view of Anderson teach wherein the wireless communication unit and the antenna are configured for electromagnetic-signal transmission and electromagnetic-signal reception (Xue, wireless transceiver [TX, RX] and antenna 810 are configured for electromagnetic-signal transmission [transmit channel 801] and electromagnetic-signal reception [receive channel 803], Fig. 8, Paras. [0115] and [0116]).
Regarding Claim 14, it is similarly rejected as Claim 1. The method can be found in Xue (method using FHSS transmission implemented by at least a first ear-worn electronic device, Fig. 2, Para. [0087]).
Regarding Claim 22, Xue in view of Solomko, and further in view of Anderson teach the processing unit is configured to place the hearing device in the idle mode in response to the hearing device being in a state that is identified based on the reflected power signal (Anderson, the proximity sensor can be placed in a standby mode [idle mode] when the main electromagnetic signal is being properly transmitted or received again i.e. when the reflected power at a third port of the directional coupler falls below a set threshold, Para. [0026]; reflected power at the third port is reflected power transmitted from the antenna along the directional coupler 4 back to wireless communication unit 2, Paras. [0025]-[0027]).
4. Claim(s) 13 is rejected under 35 U.S.C. 103 as being unpatentable over Xue et al. (U.S. Pub. No. 2022/0217464 A1, hereinafter "Xue") in view of Solomko (U.S. Pub. No. 2016/0266185 A1) in view of Anderson et al. (U.S. Pub. No. 2011/0050446 Al, hereinafter "Anderson"), and further in view of Jurg et al. (WIPO Pub. No. WO 2018/036638 A1, hereinafter "Jurg").
Regarding Claim 13, Xue in view of Solomko, and further in view of Anderson teach a charger (Xue, hearing device 100A, 100B cooperates with a charging unit, Para. [0078]);
wherein the charger is configured to charge a rechargeable battery of the hearing device (Xue, charging unit implements a charging process to charge rechargeable battery 110a, 110b, Para. [0078]).
Xue in view of Solomko, and further in view of Anderson fail to explicitly teach wherein the hearing device is configured to be operated in the idle mode when connected to the charger.
However, Jurg teaches wherein the hearing device is configured to be operated in the idle mode when connected to the charger (hearing device 1 is configured to operate in idle mode when connected to the charger, Figs. 1 and 2, Pg. 16, Lns. 1-14).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue in view of Solomko, and further in view of Anderson) to include operating in idle mode when connected to a charger (as taught by Jurg). Doing so will cause the sound system of the hearing device to operate in low power mode (Jurg Pg. 16, Lns. 1-14).
5. Claim(s) 15, 16, 18, and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Xue et al. (U.S. Pub. No. 2022/0217464 A1, hereinafter "Xue") in view of Solomko (U.S. Pub.

No. 2012/0082329 A1, hereinafter "Neumeyer").
Regarding Claim 15, Xue in view of Solomko, and further in view of Anderson fail to explicitly teach wherein the act of placing the hearing device in the idle mode comprises controlling a hearing device setting in response to the hearing device being in a state that is identified based on the reflected power signal.
However, Neumeyer teaches wherein the act of placing the hearing device in the idle mode comprises controlling a hearing device setting (hearing aid 100 setting is controlled to place the hearing device in idle mode, Para. [0026]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue in view of Matlin, and further in view of Anderson) to include controlling hearing device setting (as taught by Neumeyer). Doing so will conserve battery power and extending the battery life of hearing aid (Neumeyer Para. [0027]).
Regarding Claim 16, Xue in view of Solomko in view of Anderson, and further in view of Neumeyer teach wherein the hearing device comprises at least one hearing device transducer (Xue, mic 112a, 112b, and speaker 108a, 108b, Figs. 1D and 1E), and wherein the hearing device setting is an on/off setting of the transducer (Neumeyer, hearing aid 100 turn off sound processing, Para. [0026]).
Regarding Claim 18, Xue in view of Solomko, and further in view of Anderson teach further comprising a transducer (Xue, mic 112a, 112b, and speaker 108a, 108b, Figs. 1D and 1E).
Xue in view of Solomko, and further in view of Anderson fail to explicitly teach wherein the processing unit is configured to place the hearing device in the idle mode by controlling an on/off setting of the transducer.
However, Neumeyer teaches wherein the processing unit is configured to place the hearing device in the idle mode by controlling an on/off setting of the transducer (hearing aid 100 is placed in idle mode and turns off sound processing, Para. [0026]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue in view of Solomko, and further in view of Anderson) to include controlling an on/off setting of the transducer (as taught by Neumeyer). Doing so will conserve battery power and extending the battery life of hearing aid (Neumeyer Para. [0027]).
Regarding Claim 19, it is similarly rejected as Claim 18.
6. Claim(s) 17 is rejected under 35 U.S.C. 103 as being unpatentable over Xue et al. (U.S. Pub. No. 2022/0217464 A1, hereinafter "Xue") in view of Solomko (U.S. Pub. No. 2016/0266185 A1) in view of Anderson et al. (U.S. Pub. No. 2011/0050446 Al, hereinafter "Anderson") in view of Neumeyer et al. (U.S. Pub. No. 2012/0082329 A1, hereinafter "Neumeyer"), and further in view of Caren et al. (U.S. Pub. No. 2008/0165994 A1, hereinafter "Caren").
Regarding Claim 17, Xue in view of Solomko in view of Anderson, and further in view of Neumeyer fail to explicitly teach wherein the hearing device setting is a gain setting.
However, Caren teaches the hearing device setting is a gain setting (volume of signal can be controlled by adjusting the gain of amplifier 111, Par. [0027]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the hearing device (as taught by Xue in view of Solomko in view of Anderson, and further in view of Neumeyer) to include a gain setting (as taught by Caren). Doing so will conserve battery power and extending the battery life of hearing device.
