Abstract: An electronic device described herein includes a sensing unit having at least one sensor to acquire sensing data. An associated computing device extracts sensor specific features from the sensing data, and generates a motion activity vector, a voice activity vector, and a spatial environment vector as a function of the sensor specific features. The motion activity vector, voice activity vector, and spatial environment vector are processed to determine a base level context of the electronic device relative to its surroundings, with the base level context having aspects each based on the motion activity vector, voice activity vector, and spatial environment vector. Meta level context of the electronic device relative to its surroundings is determined as a function of the base level context, with the meta level context being at least one inference made from at least two aspects of the plurality of aspects of the base level context.

Abstract: An electronic device includes first and second transistors coupled in series between first and second source voltage levels. An inductor is coupled between a node coupling the first and second transistors and a load. Control logic is operative to generate control pulses operative to switch the first and second transistors. The controller generates the control pulses as a continuous stream of control pulses in a continuous conduction mode, and skips generation of some control pulses in a discontinuous conduction mode in response to a pulse skipping signal. A pulse skipping circuit is operative to generate a sense voltage as a function of an inductor current in the inductor, compare the sense voltage to ground, and generate a pulse skipping signal to the control logic when the sense voltage is below ground.
