An acoustic module with a transducer and a solid waveguide. The transducer and waveguide may be curved to focus the acoustic energy along a focal line. The transducer, the top surface of the waveguide and the bottom surface of the waveguide may extend along coaxial curves. The waveguide may include a recess closely receiving the transducer. The waveguide may include an integral skirt that provides a thermal mass. The acoustic module may include a space to accommodate thermal management options. For example, the acoustic module may include a heatsink, an active ventilation system and/or a phase change material. The ultrasound device may include a controller configured to perform a uniformity scan sweep during supply of operating power to the transducer. The uniformity scan sweep can extend through a frequency range that includes the operating point of the acoustic module and does not exceed an acceptable efficiency loss.

A remote device in accordance with the present invention includes an adaptive power receiver that receives wireless power from the wireless power supply by induction. The adaptive power receiver may be switched among two or more modes of operation, including, for example, a high-Q mode and a low-Q mode. By controlling the switching between modes, the amount of energy received by the adaptive receiver may be controlled. This control is a form of adaptive resonance control or Q control.

The display may include capacitive touch sensors and include an array of capacitive film segments or traces integrated into the display. The control system may include a self-contained electronics module that can be tested and calibrated before installation in the ATS. A dust sensor assembly may be integrated into the electronics module. The front cover may be attached with a mechanical attachment at the top and a magnetic attachment on the bottom. The ATS may include a filter retainer assembly with a rotating clip configured to perform in a cam-like manner to firmly clamp the particulate filter and carbon filter in place.

A wireless remote sensor () that is powered by an inductive transmitter () and is configured to produce an oscillating wave that varies based on one or more sensed parameters. The oscillating wave is communicated to the inductive transmitter () by reflected impedance, where it can be detected to determine the sensed value(s). In another aspect, the present invention provides a wireless remote sensor with a Wheatstone bridge arrangement having an internal resonant circuit to produce an electromagnetic field indicative of the sensed value. In a third aspect, the present invention provides a wireless remote sensor with optical feedback from a reference circuit and a sensor circuit. In a fourth aspect, the present invention provides a wireless remote temperature sensor having coils printed on a material with a high coefficient of thermal expansion so that the size and/or shape of the coils varies as the temperature increases or decreases.

System and method for measuring variable impedance elements in a wireless sensor

A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

System and method of providing communications in a wireless power transfer system

The present invention relates to wireless power supplies adapted to supply power and communicate with one or more remote devices. The systems and methods of the present invention generally relate to a communication timing system that may ensure information being communicated does not overlap with that of another device, preventing data collisions and information from going undetected. With information being communicated in a way that addresses or avoids potential communication issues in multiple device systems, the wireless power supply may control operation to effectively supply wireless power.

A wireless power receiver capable of receiving wireless power from close-coupled and mid-range wireless power supplies. The wireless power receiver includes a principal and supplemental receiver circuits. The principle receiver circuit is adjustable to operate in a close-coupled mode or a resonator mode. In close-coupled mode, the principle receiver circuit is coupled to the power input of a remote device and functions as the principle power source. In resonator-mode, the principle power circuit is electrically disconnected/isolated from the remote device and forms a closed resonant loop to function as a resonator that amplifies an electromagnetic field from a mid-range wireless power supply. The supplemental receiver circuit is coupled to the power input of the remote device and is configured to receive wireless power from the resonator and function as the power source when the principle receiver circuit is in the resonator mode.

A wireless power transfer component with a selectively adjustable resonator circuit having a Q control subcircuit that varies the Q factor of the resonator circuit to control the amount of power relayed by the resonator circuit. The resonator circuit may be in the wireless power supply, the wireless power receiver, an intermediate resonator or any combination thereof. The resonator circuit may be actively configured based on a feedback circuit. The feedback circuit may sense a characteristic in the secondary circuit or elsewhere and actively operate the control subcircuit based on the sensed characteristic. The feedback circuit may cause the Q control subcircuit to change (reduce or increase) the Q factor when the sensed characteristic crosses a threshold value. The Q control subcircuit may include a variable resistor having a value that can be varied to adjust the Q factor of the resonator circuit.
