Abstract: A finger operated control device includes at least one finger portion that covers at least 30% of a surface area of skin around a distal phalanx of a finger and piezoelectric sensors coupled to the finger portion and having a plurality of electrodes, where at least two of the electrodes are separated by a material with piezoelectric properties. The at least one finger portion may be thimble shaped and may be made of polymer. The at least one finger portion may be a piezoelectric polymer or polyvinylidene fluoride. A distance between at least 50% of the electrodes may be between 0.1 and 5 mm or between 0.5 and 2 mm. A number of electrodes may be between 5 and 2000 or between 20 and 200. The finger operated control device may also include a computing device coupled to the finger portion using at least a wireless and/or wired connection.

Abstract: A method for producing and detecting a transmit signal for frequency-modulating (FM) audio transmission systems, in particular for audio radio transmission systems, includes transmitting a first signal component (useful signal) that comprises audio information, and transmitting a second signal component (additional signal) that contains status information and/or control information, wherein after FM demodulation, the second signal component comprises main spectral components below the audio information useful spectrum in the baseband of the transmit signal. This method can be achieved using a circuit including a programmable phase locked loop (PLL) that determines a transmit frequency, whose divider and/or counter register is periodically reprogrammed by a microcontroller in such a way that the unmodulated carrier of the transmit frequency is periodically deflected from its fundamental frequency.
