Abstract: A communication system uses simple microwave transmitters disposed along roadways and in-vehicle mounted receivers to transmit encoded signals to produce location-specific commercial, traffic regulatory, emergency and other information to operators of motor vehicles. An optional remote interface links transmitters to regulatory and commercial users in real-time. A microprocessor in the receiver uses the coded signals to produce messages from prerecorded messages or from message parts stored in a replaceable memory device, and to provide the mes-sages either audibly, visually or both. The microprocessor functions under operator supplied instructions to select certain message types for display and to reject unwanted messages. The memory device is recorded in one or more languages to allow the operator to select a preferred lan-guage for message presentation.

Abstract: An oil filter cover has a housing with a cylindrical sidewalk an open end, and an opposing closed end. A cavity in the housing extends through the open end and is adapted to receive an oil filter canister. An annular flange circumscribes the open end of the housing and extends inward from the sidewall to partially close around and seal against the oil filter canister. A piercing member extends into the cavity from the closed end to puncture the canister. The piercing member is mounted to a plate which is located in the cavity and abuts the closed end. Further, a series of longitudinal ridges extend into the cavity from the housing sidewall and are spaced circumferentially about the cavity. Each ridge extends at least partially between the open end and the closed end of the housing with some of the ridges extending to abut and hold the piercer mounting plate against the closed end. A protective sleeve is slip-fit over the housing to minimize damage to the cylindrical sidewall from a protruding structure adjacent the oil filter.

Title: Expert system for detecting high impedance faults
Inventor: RUSSELL B DON
IPC: G06F11/25
Filed: 1994-09-28
Granted: 2005-03-22
Abstract: An expert detection system (10) includes a method and apparatus for detectin g high impedance faults occurring on a distribution circuit (12) coupled to an AC power source (14). Based upon an expert's knowledge of high impedance fau lt behavior and the performance of various fault detection techniques, the expe rt forms a belief (120) as to whether a high impedance fault has indeed occurre d. The expert's beliefs may be adjusted (130) with an elliptic formula, and the n used to weight the status output of each technique. The weighted multiple technique outputs are combined to determine whether a high impedance fault h as occurred. The expert's beliefs are calibrated during initial start-up (160) by comparison with a confirmed performance history of the detector using a scoring rule (170). The belief calibration may be included during operation to provide on-line adaption of the expert detector (10) to the changing situations of the distribution circuit (12).

Title: Stereo matching method and disparity measuring method
Inventor: ONDA KATSUMASA
IPC: H04N13/00
Filed: 1995-06-06
Granted: 1999-07-27
Abstract: A method of stereo matching and determining the disparity of stereo images with as small amount of computations as possible, and a method of measuring the disparity capable of absorbing a matching error which may occur, two right and left images are obtained by two imaging devices at imaging phase. The right and left images obtained at imaging phase have the characteristics thereof extracted respectively at characteristic extraction phase. The resulting two right and left characteristic images are matched at the subsequent stereo matching phase. At stereo matching phase, the window on one of the characteristic images providing a reference is scanned according to a predetermined scanning rule. A window providing a unit of matching is sequentially set, and matching with the other characteristic image is performed for each window thus set. Disparity determination phase divides the reference characteristic image into blocks of predetermined size, generates a histogram using the disparity obtained by matching of the window contained in each block, and determines a disparity at the histogram peak as the disparity of the particular block.

Abstract: An apparatus and a method for minimizing the turn on time for a receiver operating in a discontinuous receive mode. In a communication unit the receiver receives a signal (118) having desirable data (word A) and undesirable data (word B). The receiver (104) has a discontinuous receive mode of operation wherein the receiver (104) is turned on when expecting the desirable data (word A) and turned off when expecting the undesirable data (word B). A duration of time that the receiver (104) has been turned off is determined. The receiver (104) is turned on at a time prior to the arrival ofthe desirable data (word A) responsive to the duration of time that the receiver (104) has been turned off. The present invention advantageously minimizes the turn on time for the receiver (104) operating in a discontinuous receive mode to save current drain.

Abstract: Fluxing and soldering terminals on a printed circuit board in an in-line process in which a wall of flux is directed against a surface of the board which moves in inclined manner as it passes through a fluxing station and towards a soldering station.  The process controls flux application to decrease the amount of flux applied from the leading end to the trailing end of the board, the board inclination resulting in flow of flux to redistribute it towards providing a constant flux thickness for the soldering step.  Particularly useful for processes involving "no-clean" flux application where residual flux after soldering is to be avoided because of potential electrical problems.
