Abstract: A method for providing digital communication over an acoustic channel is disclosed. The method includes dividing an operating frequency band of the acoustic channel into multiple adjacent non-overlapping subbands of an equal bandwidth, selecting subbands based on a symbol to be transmitted, generating a signal with linear frequency modulation in each of the selected subbands, combining the signals with linear frequency modulation, and transmitting the combined signals to the acoustic channel through an acoustic system, wherein slopes of linear frequency modulation for the signals with linear frequency modulation are equal.

Abstract: Techniques and examples pertaining to controlling power consumption of a mobile terminal are described. First information regarding at least one aspect of a mobile terminal, as sensed by the at least one sensor, may be received. Second information related to the first information may be transmitted to a remote terminal. Third information may be received from the remote terminal. The third information may be determined by the remote terminal based at least in part on the second information, information about data to be transmitted to or from the mobile terminal, one or more wireless communication variables, or a combination thereof. At least one operational parameter of a wireless transceiver of the mobile terminal may be controlled based on the third information.

Abstract: Methods and circuits for power supply arrangement and control are disclosed herein. More specifically the application relates to a control method and a controller for a DC-to-DC converter, such as a synchronous Buck converter, which implements a transient detection scheme together with response generation to allow the converter to recover from a positive and/or negative load current step in the robust way, with low undershoot/overshoot at the output voltage. The control method may be implemented by either an analog or a digital circuit. The controller may be integrated with existing controller schemes (such as voltage-mode controllers) to provide superior dynamic performance during large-signal transient conditions while providing stable operation during steady state conditions. The methods and circuits provided herein are applicable to Buck converters and Buck-derived converters such as forward, push-pull, half-bridge, and full-bridge converters.

Abstract: Methods and systems for contactless optical measurement of geometrical dimensions of articles are disclosed herein. A system according to the present disclosure may implement an arrangement of one or more measured articles, two imaging setups, a reflecting surface and a reference object. Geometrical dimensions of the one or more measured articles may be derived from dimensions of images formed in the imaging setups.
