Abstract: A method of operating a microcontroller to perform a Fast Fourier Transform, the method including receiving, by the microcontroller, N samples from a signal; and performing, by the microcontroller, a first butterfly operation of the Fast Fourier Transform before all of the N samples have been received from the signal, based on the performing of the first butterfly operation, the microcontroller performs the Fast Fourier Transform at a higher performance to power efficiency than a Fast Fourier Transform operation that begins after all of the N samples are received.

Abstract: A wireless power transmitting/receiving device includes a power transmitting/receiving element, a plurality of switches, a current sensor and a controller. Each of the plurality of switches has a control terminal and a conduction terminal, with the conduction terminal being coupled to the power transmitting/receiving element. The current sensor senses a current through the power transmitting/receiving element, and the controller is configured to control the plurality of switches based on the sensed current.

Abstract: An electronic device receives wireless signals encoded with data in an amplitude-shift keying format. The electronic device passes the wireless signals through a low-pass filter. The low-pass filter has a cutoff frequency between a first frequency associated with data values of a first type and a second frequency associated with data values of a second type. The low-pass filter has the effect of changing the wireless signal from the amplitude-shift keying format to an on-off keying format without losing the data. The electronic device decodes the data from the wireless signal in the on-off keying format.

Abstract: A microelectromechanical device is provided. A vibrating structure gyroscope included in the device employs a temporal differential sensing method alone or a spatial differential sensing method in combination with the temporal differential sensing method. When used in combination, the temporal sensing method may be applied before the spatial sensing method or applied after the spatial sensing method. The temporal differential sensing samples signals at times t1 and t2 when velocity of a sensing mass within the vibrating structure gyroscope is maximum and has an opposite sign. The temporal sensing method improves Euler and Centrifugal forces cancellation and increases the signal to noise ratio if forces remain equal at times t1 and t2. Applying a high sampling speed can result in times t1 and t2 being sufficiently close to each other and therefore cancel any error terms associated with Euler and Centrifugal forces.
