Abstract: Various embodiments of the present technology may comprise methods and apparatus for a touch sensor. The capacitive touch sensor may comprise a plurality of drive electrodes and a reception electrode, wherein two capacitors are formed. Under various conditions, the capacitive touch sensor may be configured to trigger a touch event in the presence of a human finger and trigger a non-touch event in the presence of water.

Abstract: A Schottky device includes a plurality of mesa structures where one or more of the mesa structures includes a doped region having a multi-concentration dopant profile. In accordance with an embodiment, the Schottky device is formed from a semiconductor material of a first conductivity type. Trenches having sidewalls and floors are formed in the semiconductor material to form a plurality of mesa structures. A doped region having a multi-concentration impurity profile is formed in at least one trench, where the impurity materials of the doped region having the multi-concentration impurity profile are of a second conductivity type. A Schottky contact is formed to at least one of the mesa structures having the doped region with the multi-concentration impurity profile.

Abstract: An imager may include depth sensing pixels that provide an asymmetrical angular response to incident light. The depth sensing pixels may each include a substrate region formed from a photosensitive portion and a non-photosensitive portion. The depth sensing pixels may include mechanisms that prevent regions of the substrate from receiving incident light. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses. Each of the depth sensing pixel pairs may effectively divide the corresponding imaging lens into separate portions. Depth information for each depth sensing pixel pair may be determined based on the difference between output signals of the depth sensing pixels of that depth sensing pixel pair. The imager may be formed from various combinations of depth sensing pixel pairs and color sensing pixel pairs arranged in a Bayer pattern or other desired patterns.

Abstract: In one embodiment, electrostatic discharge (ESD) devices are disclosed.

Abstract: A switching power supply (10) uses a switching regulator (18) that is capable of operating in a dual mode with either primary side regulation or secondary side regulation. The primary and secondary side regulation schemes generate opposite phase feedback signals. The switching regulator has first (56, 62) and second (70, 74) detectors on the feedback input which detect when the feedback signal is less than a first value and also detect when the feedback signal is greater than a second value. By monitoring either case, the switching regulator can enable and disable a gate drive signal in response to opposite phases of the feedback signal and thereby regulate the switching power supply.
