Abstract: A flashlight senses when it is picked up, and then automatically turns on. When the flashlight is released or set back down, it automatically turns off. Touch or contact sensors sense the touch of a human hand, causing a circuit in the flashlight to switch on a light source, such as an LED. The flashlight is advantageously designed so that when grasped or picked up, the fingers of the user's hand lay over touch sensors. Various types of touch sensors may be used. The touch sensors may operate electrically, and without any movement, or moving parts.

Abstract: A solar circulator and converter which is driven by a solar generator; the fan or impeller is mounted in an impeller housing. On the surface opposite the impeller housing is a solar panel with mounting elements which can be affixed or mounted on such things as car windows. The impeller or fan blows and circulates air inside the car whether the car is stationery or in motion. The circulator also converts part of the solar radiation into forms of energy other than heat and thereby reduces temperature.

Abstract: Optical circuits are disclosed having a source waveguide, a first tap waveguide and a second tap waveguide. Optical power is transferred via evanescent coupling from the source waveguide to the first tap waveguide and from the first tap waveguide to the second tap waveguide such that power loss is minimized. Also disclosed are methods for fabricating optical integrated circuits.

Abstract: The invention relates to an optical device which carries multiple optical signals where the optical device has a plurality of distal waveguides some of which may be configured to control insertion loss among the multiple optical signals.

Abstract: This relates generally to optical waveguide-based devices including dynamically programmable optical attenuators. In particular, this provides an optical attenuator having a Mach Zehnder configuration with reduced polarization dependence. The devices herein facilitate the implementation of continuously-variable optical attenuators, optical shutters, and optical switches in an integrated photonic circuit.
