摘要： A device includes a voltage source configured to selectively drive a first wire and a second wire with a first voltage level. The device further includes an adjustable current source configured to selectively discharge the first and second wire. The device further includes a control circuit configured to output data and power by way of the first and second wire by selectively coupling the first wire to the voltage source and the second wire to the adjustable current source such that, during a first time period, the first wire has the first voltage level and the second wire has a second voltage level. The data and power is output by also selectively switching the couplings of the first time period such that, during a second time period subsequent to the first time period, the first wire has the second voltage level and the second wire has the first voltage level.

摘要： A cochlear implant configured to be implanted within a patient may comprise an integrated circuit including a driver configured to generate a back telemetry signal encoded with information to be transmitted over a wireless communication link to a sound processor located external to the patient. The cochlear implant may also comprise a filter network that includes a first plurality of impedance components including a damping resistor, and a first and a second impedance component such as a capacitor or an inductor. The cochlear implant may also comprise an isolation network including a second plurality of impedance components configured to isolate, from the filter network and the driver, a forward telemetry signal received by the cochlear implant from the sound processor.

摘要： An exemplary system includes a sensor configured to output sensor data and a hearing device comprising a processor. The processor of the hearing device may be configured to detect, based on the sensor data, a triggering event that occurs during use of the hearing device by a recipient of the hearing device. The triggering event may be indicative of possible damage to at least one of the hearing device or the recipient. The processor may further, apply, in response to the detecting of the triggering event, stimulation to the recipient, detect a signal that occurs in response to the stimulation and that is recorded by an electrode associated with the hearing device, compare the signal to a baseline signal recorded by the electrode prior to the triggering event, and determine, based on the comparing of the signal to the baseline signal, an operational effectiveness state of the hearing device.

摘要： An illustrative timing-based power control apparatus includes a signal generation circuit and a power control circuit. The signal generation circuit is configured to generate a carrier signal for wireless transmission of output power and output data, the carrier signal associated with a first fundamental component having a particular frequency, a particular phase, and a first amplitude. The power control circuit is configured to generate a time-adjusted version of the carrier signal that maintains an amplitude of the carrier signal and adjusts a timing profile of the carrier signal such that a second fundamental component associated with the time-adjusted version of the carrier signal has the particular frequency, the particular phase, and a second amplitude lower than the first amplitude. The second amplitude may be associated with a target power level for the output power of the wireless transmission. Corresponding systems and methods are also disclosed.

摘要： An amplitude shift keying (ASK) modulation system includes a linear regulator circuit powered by input direct current (DC) power at a first voltage level and that generates regulated DC power at a second voltage level tracking the first voltage level. The system also includes an intermediate DC power switching circuit that receives a digital data signal and selectively couples an intermediate power node with the input DC power at the first voltage level when the digital data signal represents a first binary value, and with the regulated DC power at the second voltage level when the digital data signal represents a second binary value. The ASK modulation system also includes a radio frequency (RF) driver circuit powered by intermediate DC power received at the intermediate power node and that delivers RF output power representative of the digital data signal to a load at an RF carrier frequency.

摘要： A system may include a device configured to be implanted within a recipient and that includes an integrated circuit. The integrated circuit may include a first node configured to provide a bandgap reference voltage and a second node configured to provide a CTAT voltage. The first node may be coupled to a first input of an ADC and the second node may be coupled to a second input of the ADC. The system may also include a processor communicatively coupled to an output of the ADC. The processor may be configured to determine, based on the output of the ADC, the CTAT voltage. The processor may be further configured to determine, based on the CTAT voltage, a temperature of the device.
