Abstract: Wireless power and data transfer can be implemented for powering and communicating with a variety of devices, in a manner that facilitates device access under such wireless power conditions. As consistent with one or more embodiments, wireless power and data are communicated in an apparatus such as a mobile device having a power circuit (e.g., a battery) that powers a processor under normal operating conditions, and that also operates in a low-power state (e.g., in which the processor is not operating and/or not operating using the power circuit). Power is generated using wireless power signals and used to power the power circuit and to both extract and store data from wireless data signals. With this approach, data can be transferred in a low-power state, and the processor can use the stored data upon transitioning to an on state in which the processor is active and powered by the power circuit/battery.

Abstract: A system for producing a mechanical haptic pattern based on linear resonance actuator (LRA) signal is disclosed. The system includes an actuator displacement sensor, the actuator displacement sensor configured to apply an alternating measurement signal at a predetermined frequency to an actuator motor. The actuator displacement sensor configured to use a measure of a voltage across and a current through the actuator motor to determine its impedance at the predetermined frequency and determine an estimated displacement of the actuator motor using said impedance and a predetermined displacement-impedance function. The system also includes a controller configured to accept the LRA signal and the estimated displacement, wherein the controller is configured to alter the input LRA signal according to the estimated displacement to limit excursion of a moving part of the actuator motor.

Abstract: Various aspects of the present disclosure involve communications, and more specifically wireless communications with modulation. As may be implemented in accordance with one or more embodiments, a rectifier having a plurality of active circuits operates in first and second modes to modulate signals communicated via an antenna as follows. The first mode is at least a half-active mode in which at least one of the active circuits passes the signal, and the second mode consumes less power than the first mode. A modulator modulates a waveform of the signal by selectively operating at least one of the plurality of active circuits, therein setting an impedance of the rectifier and modulating an amplitude of the signal.
