Title: Method for controlling a photosensitive device for producing good quality images
Inventor: CHAUSSAT CHRISTOPHE
IPC: H04N5/365
Filed: 2000-06-27
Abstract: The invention concerns a method for controlling a photosensitive device comprising at least a photosensitive point (P1 to P9) with a photodiode (Dp) connected to a switch element (Dc, T). The method consists in subjecting the photosensitive point to a cycle of successive images. Between a first image cycle and a second image cycle it consists in producing a maintenance phase (PHM) ending at the beginning of the second image cycle. During said maintenance phase PHM), whereof the duration is equal to several equivalent shortest possible time intervals (dt), the photosensitive point is exposed to an optical flash (FO) at the beginning of each time interval. Between the successive optical flashes, the photodiode is subjected to reverse polarisation. The junction zone between the photodiode and the switch element has substantially a similar potential (VA) at the end of each time interval (dt).

Abstract: A reciprocating saw includes a housing having an upper surface and a side surface, and a blade holder supported on the end of a reciprocating saw bar. The blade holder is adapted to support a saw blade such that the resulting cutting plane lies outboard of one of the housing's surfaces, while a reference plane, orthogonal to the cutting plane and intersecting a cutting edge of the blade, lies outboard of the other of the housing's surfaces. Preferably, each surface includes a flat, and the blade's cutting edge is supported proximate to an intersection of the planar extensions of the flats. A wobble drive assembly including a single wobble plate with an integral counterweight advantageously permits a relatively outboard position of the saw bar on the housing to reduce bending moments on the bearings supporting the saw bar.

Abstract: Methods and devices are provided for determining the presence and/or concentration of at least one analyte in a sample (24) of low transmissivity.  In the subject methods, a forward beam (32) and a backward beam (33) are produced by or introduced into an interferometer (22) from at least one infrared radiation source (21). The forward beam is passed into the sample and then collected to produce a sample beam while the backward beam is passed into a reference and then collected to provide a reference beam. The sample and reference beams are recombined either optically into a null beam (36) which is detected at a single detector (26) or electronically nulled after detection on two separate detectors. The presence, and often amount, of at least one analyte in the sample is then derived from the detected null beam. Also provided are devices for practicing the above methods. The subject methods and devices are suitable for use in a variety of different applications, including the detection of the presence, and amount, of one or more blood analytes in a physiological sample, such as blood, tissue or derivatives thereof.

Abstract: A system and method for deploying a belt-line inflatable structure with substantial axial tension, the system including an inflatable structure seri al assembly (200, 204) held at its ends by two static anchors (202, 208). The serial assembly can be independent inflatable structures connected together (200, 204) or one continuous inflatable structure (910). One or more dynamic  anchors (205), mounted opposite the static anchors, restrains the serial assembly at an intermediate portion of the serial assembly such that the serial assembly has a first axis between the one static anchor and the one o r more dynamic anchors and a second axis between the other static anchor and t he one or more dynamic anchors. The dynamic anchor(s) (205) allow the serial assembly to move axially along the first axis and the second axis and to equalize the axial tension of the serial assembly along the first and second  axes. The system can further include a shield (600) covering the inflatable structures.
