Title: Apparatus for measuring the deformation of damaged vehicles and for reconstructing crime scene
Inventor: CHARTRAND FRANCOIS
IPC: G01B5/20
Filed: 1994-03-29
Abstract: An apparatus for measuring on the site of an accident the three-dimensional deformation of a damaged vehicle comprises a reference frame and a distance measuring device. The reference frame comprises a first straight frame portion installed in front of the vehicle parallel to the transversal axis thereof, a second elongated straight frame portion installed on the side of the vehicle parallel to this vehicle's longitudinal axis, and a third elongated straight frame portion installed at the rear of the vehicle parallel to the the transversal axis. When the deformation is situated in front of the damaged vehicle, the first frame portion defines a first axis of a three-dimensional coordinate system, the second axis of this coordinate system being located in a vertical plane in which the first elongated frame portion is lying. The distance measuring device measures distances between the first frame portion and the body of the damaged vehicle in the region of the three-dimensional deformation, by measuring distances along the second and a third axis of the three-dimensional coordinate system. The distance measurements along with knowledge of the spatial relationship between the first frame portion and the non deformed part of the vehicle body give very accurate information about the three-dimensional deformation of the vehicle.

Patent CA-2144615-A1 (CA)
Inventor: EATON NEIL B
IPC: H02M7/162
Filed: 1995-03-14
Abstract: There is disclosed a system for controlling the junction temperature of gated semiconductor cells connected in parallel. Briefly, a temperature sensor is provided for each cell to provide a signal proportional to the temperature of the cell. This signal (proportional to temperature) is monitored by a controller which selectively energizes the cells to allow current flow through the cells when the temperature reading of a cell is below average temperatures. Cells having temperatures above average have conduction periods reduced. By selectively energizing cells responsive to cell temperature, fewer cells are required to ensure continuous current levels passing through the cells do not result in destructive junction temperatures damaging the semiconductor device in each cell.

Title: A method and apparatus for prioritizing a telephone call according to a level of service of an originator
Inventor: BAKER MARK C
IPC: H04M3/42
Filed: 1995-03-29
Abstract: A method and apparatus that allows different likelihoods of call completion during very heavy call loading conditions to be supplied to different customers.  Customers are assigned to different levels of service and these levels of service are used to manage call completion in throughout the telecommunication network during very heavy call loading periods.  Thus, a securities broker may have a higher likelihood of completing a call near the close of a trading session than the average telephone customer.  However, each caller may be offered an opportunity to immediately increase his or her level of service and thus likelihood of completing a call to the highest available level if a call is not completed at the caller's lower level of service.

Title: Integrated modulator and turbine-generator for a measurement while drilling tool
Inventor: LERNER DANIEL
IPC: E21B47/18
Filed: 1995-04-21
Abstract: An integrated modulator and turbine-generator includes a turbine impeller which is directly coupled by a drive shaft to a modulator rotor downstream from the impeller. The modulator rotor is further coupled by a drive shaft and a gear train to a three phase alternator downstream of the modulator rotor. The modulator stator blades are arranged downstream of and adjacent to the modulator rotor and the alternator is provided with a Hall effect tachometer. The turbine impeller directly drives the modulator rotor and the alternator generates power. The speed of rotation of the modulator rotor is adjusted by reference to the speed of rotation of the alternator as indicated by the tachometer and to a reference frequency. A control circuit including an electromagnetic braking circuit coupled to the tachometer and the stator windings of the alternator stabilizes the alternator speed and thus the rotor speed and modulates the rotor to obtain the desired frequency of the mudborne pressure wave by selectively shorting the stator windings of the alternator. During periods when braking is not applied, the alternator generates power for control and sensor electronics.

Abstract: A cover plate (28) extends over at least part of a solder reservoir (34) and has a slot (30) for a solder wave (22) to extend up above the cover plate (28). Shield gas is supplied under the cover plate (28) to blanket the solder wave (22) and prevent air from contacting the solder wave (22) and circuit boards (44) passing through the solder wave (22). Circuit boards (44) are generally supported by conveyor fingers (41, 42) at side edges and the fingers (41, 42) pass through the solder wave (22). End shrouds (50, 64) are provided at both ends of the solder wave (22) to prevent the entry of air through the conveyor fingers (41, 42) and to ensure that the side edges of the circuit board (44) are uniformly blanketed by shield gas directed to the side edges passing up through the slot (30) in the cover plate (28). The under surface, front edge back edge and side edges of a circuit board (44) are therefore uniformly blanketed by shield gas as the board passes through a solder wave (22).
