Patent number: 8971588
Abstract: A system and method for contactless handprint capture is disclosed that includes an image capture device to capture whole handprint images of a subject hand at each of a plurality of different focal distances, with the image capture device including an imaging camera and an electro-optics arrangement having a plurality of light modulating elements and polarization sensitive optical elements having differing optical path lengths based on polarization states. A control system is coupled to the image capture device to cause the device to capture the handprint images at each of the different focal distances, with each handprint image having a depth-of-focus that overlaps with a depth-of-focus of handprint images at adjacent focal distances such that redundant handprint image data is captured. The control system registers each handprint image with positional data and creates a composite handprint image from the handprint images captured at the different focal distances.

Abstract: Provided is a system for soft switching of an electromechanical relay in a lighting control system using a sensor to detect a specified non-zero position in the electrical input waveform. Following this non-zero position, an adaptive time delay is applied before activation of the relay coil. An error detection circuit measures a time error between relay operation and the zero electrical input condition. This error signal is used to update the adaptive time delay for future relay operations. Using such a procedure has been shown to limit electrical stress on the relay, and therefore lengthen its life.

Abstract: Modules, systems, and methods are provided for cooling components of an inspection or testing apparatus, such as a borescope. In some exemplary embodiments, the modules include two heat sinks, with the top-most heat sink having a fan assembly approximately centrally disposed therein. The fan assembly can be operated to draw air into the top-most heat sink, and then exhaust airflow out of the top-most heat sink such that the exhaust air passes across at least a portion of the second heat sink to help cool both the first and second heat sinks, and components of the apparatus associated therewith, using the same fan assembly. As a result, the components of the apparatus can be cooled more easily, and the performance and efficiency of these components is improved, all while reducing the overall size and weight of the inspection apparatus.

Application number: 20150054614
Abstract: A fuse assembly for interrupting fault current in an external DC circuit. The fuse assembly includes 2n fusible conductor elements, where n is an integer, wherein the fusible conductor elements extend along, and are circumferentially around, a longitudinal axis of the fuse assembly. The fusible conductor elements are connected together in series to define fuse elements and the fusible conductor elements are orientated within the fuse assembly such that current flowing along each fusible conductor element is in the opposite direction to current flowing along the fusible conductor element or fusible conductor elements adjacent to it. The fuse assembly further includes a supply terminal connected to an end of the fuse element and connectible to a DC supply, and a load terminal connected to an opposite end of the first fuse element and connectible to an electrical load.

Abstract: Coating systems suitable for use in fluorescent lamps, particularly as scattering agents within a UV-reflecting coating for the purpose of improving fluorescent lamp luminosity. Such a coating system is provided on a transparent or translucent substrate and includes a phosphor coating and a scattering agent that scatters UV rays. The scattering agent includes an inorganic powder present in a separate UV-reflecting layer adjacent the phosphor coating and/or dispersed in the phosphor coating so that the scattered UV rays are absorbed by the phosphor coating and cause the phosphor coating to emit visible light. The inorganic powder exhibits low or no absorption to UV rays having wavelengths of 185 nm and 254 nm and is not reactive with mercury.
