Abstract: The invention is a pneumatically actuated energy collection device. The device includes a support which has an energy collector thereon. A shutter is slidably attached to the support and can be moved between a first “closed” position and a second “open” position. In its first position, the shutter covers the collector and in its second position, the shutter uncovers the collector. The shutter is biased into one of the positions. A chamber is disposed adjacent to the shutter so that when the chamber is pressurized, the shutter bias is overcome and the shutter is moved between the first position and the second position.

Abstract: This invention consists in a nonimaging device for concentration or collimation of radiation on a receiver or from an emitter (14), depending on the case. The device is made up of the lens (50), which surrounds the receiver and consists of the aspheric surface (21), and the lens (15), whose upper refractive surface (16) may be aspheric, while the lower surface is aspheric (17) in its central portion (between points 18 and 19) and has a structure with discontinuous slope (20) in its external portion, in which the faces (22) fundamentally refract the rays while the faces (23) reflect them by total internal reflection. The design method provides that the device properties of concentration/collimation are noticeably superior to those of the existing inventions. Possible applications of this lens include: radiation sensors, illumination systems with LEDs, wireless optical communications and photovoltaic solar energy.

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: An electro-optic aperture includes an electrochromic medium at least partially disposed thereon. The electrochromic medium is operable to adjust the transmissivity of light through the aperture in response to an electrical signal applied to the aperture. The aperture preferably is operable to significantly attenuate all wavelengths of energy in an area where the electrochromic medium is energized, thereby allowing the energy to pass through an area of the aperture which either does not include the film or is not being energized. Preferably, the electro-optic aperture is implemented with a silicon imaging array sensor, and functions to improve focusing of images when there is sufficient light available in the scene, while allowing a greater amount of light therethrough when lighting conditions darken. Preferably, the electro-optic aperture is operable to significantly attenuate energy during daytime or other higher intensity lighting conditions, and may be selectively deactivated or otherwise adjusted at nighttime or in other darkened lighting conditions, such that a greater amount of energy may be received by the sensor in order to improve illumination of the image being captured by the sensor.

Abstract: A method and apparatus for measurement of at least one of brightness, flow velocity and temperature of radiant media are provided. A substantially collimated beam of light having a selected frequency is directed to a linear polariser. The linearly polarised output is directed to an electro-optically active birefringent crystal to separate the output into two characteristic waves and to introduce a first fixed phase delay between the characteristic waves. The birefringent crystal is selectively electro-optically modulated to introduce a second variable phase delay between the characteristic waves and the characteristic waves are combined to interfere prior to detection.

Abstract: A symmetric monitor calibrator for mounting on a cathode ray tube or monitor with a surface. The calibrator has a case that holds electronic and optic components. Suction cups hold the calibrator to the surface, in which the suction cups are attached to the end of supporting elements that surround the case. At least three supporting elements with a common connecting point to form one support structure are connected to the top of the case. The supporting elements extend out creating a greater diameter than the case. The supporting elements and therefore suction cups uniformly surround the center point of the case to prevent rotation caused by the effects of gravity.

Abstract: The invention relates to a process and a device for detecting or recognizing an object by means of color recognition or brightness evaluation, whereby radiation emitted by a radiation source on the object and radiation reflected from the object is recorded by a photosensitive element such as a color-recognizing sensor. In order to be able to detect objects with a higher measuring exactitude, whereby changes in distance between object and light-sensitive element should not basically lead to a measurement falsification, it is suggested that reflected radiation be guided to the photosensitive element by means of a light-guiding element tapering in the direction of the photosensitive element.

Abstract: Many applications of radiant energy transducer systems call for specific performance characteristics over predetermined fields or surfaces. Constructive occlusion utilizes diffuse reflectivity and a mask sized/positioned to occlude an active optical area, such as an aperture of a reflective cavity, to provide tailored performance characteristics. Constructive occlusion alone or in combination with other techniques enable tailoring of the performance of a radiant energy transducer system to meet requirements of specific applications. One mechanism used to further tailor performance involves a non-diffuse reflective shoulder along a peripheral section of the mask and cavity system. Another technique involves using a retro-reflective surface, for example along a portion of the periphery of the system. Another technique involves use of a reflective wall along one side of the system, to limit the field of view to angles on the opposite side of the axis of the mask and cavity configuration.
