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: In an embodiment, information contents, such as, e.g., media contents arranged in pieces including blocks of bits, is distributed over a network including plural terminals at least one of which acts as a source of the pieces of information distributed. Various terminals in the network are configured to act as peer terminals with at least one first peer terminal sending the information to one or more second peer terminals. A set of blocks of a corresponding piece of information is received at the first peer terminal and the corresponding piece of information is reconstructed from the set of blocks received. The pieces of information distributed over the network are fountain encoded by XOR-ing the blocks in a piece, so that a received piece is reconstructable from a combination of a corresponding set of linearly independent XOR-ed blocks. The first peer terminal may start sending to the second peer terminal(s) blocks it is receiving before the corresponding piece of information is reconstructed and possibly subjected to integrity check at the first terminal. Fountain encoding the pieces of information is by means of plural sets of linearly independent XOR-ed blocks. A same piece of information is distributed to a plurality of peer terminals by sending thereto different sets of linearly independent XOR-ed blocks, thus avoiding undue redundancy in the information further propagated to other peers.

Abstract: The present disclosure is directed to multichannel transducer devices and methods of operation thereof. One example device includes at least two acquisition modules that have different sensitives and a signal processing stage that generates a blended signal representative of a lower gain signal mapped onto a higher gain signal. One example method of operation includes receiving a first signal from a first sensor having a first sensitivity, receiving a second signal from a second sensor having a second sensitivity that is different from the first sensitivity, generating a blended signal by mapping the second signal to the first signal, outputting the first signal while the first signal is below a first threshold and above a second threshold, and outputting the blended signal when the first signal is above the first threshold and when the first signal is below the second threshold.

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: 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.
