Abstract: According to an example, a method for area occupancy information extraction may include receiving a signal from a sensor, and determining a number of occupants moving within a first area based on the signal. The method may further include determining when an occupant is moving and a direction of motion of the occupant based on the signal, and determining a most likely trajectory based on the direction of motion of the occupant. The method may also include controlling, by a processor, a service in the first area based on the determination of the number of occupants, the determination of when the occupant is moving and the direction of motion of the occupant, and/or the determination of the most likely trajectory.

Abstract: Light emitting diodes (LEDs) having a sensor segment for operational feedback are described. A semiconductor stack is grown on a sapphire substrate. The semiconductor stack is segmented to form at least two segments, where one segment senses light emissions (photosensor segment) from the other segment (emitter segment). The segmentation is achieved by etching a trench or forming a segmentation layer between the segments. One segment can alternate on a predetermined basis between functioning as a photosensor segment or as an emitter segment. The photosensor segment can detect either a side light ray emitting from the emitter segment or a reflected light ray from a substrate. The photosensor segment generates a current based on the detected light ray. A detector circuit can provide operational feedback based on the sensed current.

Abstract: A first system is associated with an operating status. A second system is to affect the operating status based on usage of a shared resource. A restrictor is to control usage of the shared resource. A controller is to adjust the restrictor to control usage of the shared resource based on the operating status and a received communication indicating a resource status.
