Abstract: The invention relates to a method for controlling a wearable device using tap gestures, in particular at a carrying component of the wearable, wherein measurement data are generated by a sensor and the wearable is controlled when the measurement data are identified as tap gestures at the carrying component. The invention furthermore relates to a wearable device that can be controlled by tap gestures at the carrying component.

Abstract: A method for use by a multi-mode, dual band mobile terminal (10) for identifying a presence of a GSM1900 carrier that is channelized into first channels having a bandwidth of 200 kHz, and for distinguishing the GSM1900 carrier from at least a TDMA1900 carrier that is channelized into second channels having a bandwidth of 30 kHz.

Abstract: This invention teaches methods and apparatus for providing a low cost, low complexity, and low component count transmitter feedback function for use in mobile station transmitter linearization and self-test operations. Disclosed is a method for operating a mobile station of a type that includes a transmit chain having an output coupled to an antenna and a receive chain having an input coupled to the same or a different antenna.

Abstract: A frequency difference signal of a modulated signal (f.sub.1) and an unmodulated signal (f.sub.2) is produced maintaining the information of the frequency or phase modulation. According to the method, the time-related order of entry of the front edges of the pulses of the modulated and the unmodulated signal is controlled and the edge of the frequency difference signal in question at any moment is formed timewise at the same point as the edge of such modulated signal at which the time-related order of arrival of the modulating signal and the unmodulated signal has changed. Hereby, the frequency or phase shift of the modulated signal can be detected as an equivalent change in the frequency difference signal, and the modulation of the frequency difference signal is detected on the basis of the location of the pulse edge of the frequency difference signal.
