Patent CA-2019943-A1 (CA)
Inventor: HARUKI TOSHINOBU
IPC: H04N5/235
Filed: 1990-06-27
Abstract: An automatic exposure adjusting apparatus for use in a video camera automatically adjusts exposure based on a video signal obtained from an image sensing circuit. The automatic exposure adjusting apparatus detects a luminance signal level of the video signal and detects a first mean value which is a simple mean value per unit area of an image sensed picture. The automatic exposure adjusting apparatus also outputs a second mean value weighted every area in accordance with a luminance distribution in the image sensed picture. The automatic exposure adjusting apparatus controls the adjustment of exposure based on the first and second mean values. Such weighting of the luminance level in accordance with the luminance distribution is carried out based on the fussy inference.

Abstract: TEMPERATURE CONTROLLED CHAMBER FOR      ANALYTICAL INSTRUMENT                     ABSTRACT OF THE DISCLOSURE             A temperature controlled chamber for an analytical instrument which includes a circular conveyor for transporting assay cartridges, the chamber enclosing the outer peripheral part of the conveyor on which the assay cartridges reside. The temperature controlled chamber comprises a bottom wall of polymeric material located beneath the conveyor, an outer wall of polymeric material extending upward above the conveyor, a metallic top wall and a metallic inner wall which extends downward to the upper surface of the conveyor. Thermal control, including rapid thermal response to compensate for temperature perturbations induced by periodic introduction of assay cartridges which are at a temperature less than that of the chamber, is accomplished by heating elements located above and below the conveyor. The heating elements are pulsed by an electrical circuit at a rate substantially faster than the rate of introduction of new assay cartridges. Pulses of electric current applied to the heating elements are modulated with pulse-width modulation to adjust the temperature within the chamber in response to signals emitted by a temperature sensor located within the chamber.

Abstract: A retroreflective material providing a visual coloration includes a body member with microprisms on its rear surface.          Some of the microprisms have a retroreflective interface and the remainder have a colored non-reflective coating thereon.          As a result, light rays entering the front face which impinge upon  the prisms with the  retroreflective  interface are redirected so that they exit the material in a parallel path.          Light rays which travel to the color coated prisms are refracted from those prisms and impart a visual coloration to the material in daylight and ambient light.

Abstract: Symbol sequences of varying lengths and having logical meanings other than as network addresses (e.g., subscriber names), are assigned and used as actual telecommunications network addresses, without imposition of predefined fixed lengths, formats, or orderings on their constituent segments (e.g., given name, surname), in a call-processing arrangement that uses stored definitions of syntax and grammar of the network numbering plan.  The syntax definitions include definitions of individual address segments, called symbol strings, which have logical meanings. Each string's definition includes a string length range, a string type, and an indicator of the string's influence on call treatment (e.g., route) selection.  The grammar definitions include a matrix that defines permissible sequences of string types,including string types which cannot be dialed by users but only result from receipt of permissible sequences of strings of user-dialable types, and a matrix that defines which string types' influences on call treatment selection may be combined to select a treatment for a call.  A network digit analysis function parses a received call-control symbol sequence by using the stored syntax and grammar definitions to select a treatment for the call.
