Abstract: An electronic device uses one or more infrared sensors to detect infrared light from a person's body (e.g., a user's finger) to initiate a function of the electronic device. According to an implementation, the housing of the electronic device includes a flexible portion that opens an aperture in response to external pressure (e.g., a user pressing down on the flexible portion) to allow infrared light from the person's body to reach an infrared sensor. When the infrared sensor detects the infrared light, it generates a signal in response. A processor of the electronic device receives the signal and, in response, initiates a function of the electronic device. The function may be any function that the electronic device is capable of performing, such as a power-on function, a camera function, changing the speaker volume, and launching an application.

Abstract: A system and method for performing field measurement and testing of a plurality of widely spaced laser beams used in visual warning technology (VWT). VWT uses a combination of widely spaced laser beams, to warn civilians from approaching too close to military security areas. The widely spaced laser beams are displaced using rhomboidal prisms. Each rhomboidal prism receives a corresponding laser beam and displaces it toward a collecting lens. The lens focuses the displaced beams received thereon onto an imaging sensor for testing. Beam shutters may be used for selectively blocking one or more beams in order to test the beams separately and in different combinations.

Abstract: Radiation receiver with a photodetector and a sensor, wherein the sensor receives the radiation intensity, and a shutter arranged before the photodetector is driven in dependence on the detected incident radiation intensity. The incident radiation is supplied to the photodetector via a delay device arranged before the shutter, so that no radiation destroying the photodetector can reach the photodetector, due to the shutter having been driven, and can if necessary be kept away or absorbed by the shutter.

Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope that is used to view an image of an object. A light shielding system shields light generated by a light source and transmitted to the endoscope and a stepping motor drives the light shielding system for a plurality of predetermined time intervals. A system detects a brightness of the image during each of the plurality of predetermined time intervals and an input system inputs one of a plurality of desired brightnesses of the image. A generating system generates a predetermined number of pulses during each of the plurality of predetermined time intervals, the predetermined number of pulses being transmitted to the stepping motor and a system determines an angular position of the light shielding system. A setting system sets one of a plurality of allowed brightness ranges of the image in response to the determined angular position of the light shielding system and a system determines whether the detected brightness is within the set one of the plurality of allowed brightness ranges.
