Patent CA-2056225-C (CA)
Title: Method of hot restarting electrodeless hid lamps
Inventor: GREGOR PHILIP D
IPC: H01J65/04
Filed: 1991-11-26
Granted: 2002-06-04
Abstract: The present invention describes an apparatus and method for shutting off an electrodeless lamp such that it can be restarted instantaneously at any time. The method involves reducing the applied microwave power in a con-trolled way the moment the lamp is turned off. The reduc-tion of power is accomplished by modulating the microwave power with an ever decreasing duty factor or a decrease of analog power. This reduction in power results continually in reduced light output and lamp cooling while maintaining partial ionization of the lamp fill. Circuitry to accomplish this is also presented.
Patent CA-2056944-C (CA)
Title: Vapor storage canister with volume change compensator
Inventor: TURNER KENNETH WILLIAM
IPC: F02M25/08
Filed: 1991-12-04
Granted: 1996-11-19
Abstract: A bed of activated carbon granules is maintained tightly packed within a fuel vapor storage canister housing by a specially designed compensator. A pair of spring loaded, nested trays move axially relative to one another and push continually into the lower face of the carbon bed to keep it packed. The trays also define a continuous, self maintaining gap that is smaller than the expected carbon granule size, preventing them from falling out in spite of the swelling of the canister housing.

Granted: 2002-04-09
Abstract: The specification describes a preferred embodiment of the square-backed vehicle air foil 10 for attaching to a vehicle 12 adjacent an upper rear edge for projecting into a horizontal airstream "S" for subdividing the airstream into an inner or first airstream layer S1 and an outer or second airstream layer S2. The assembly 10 has an inner air foil element 32 that directs the first airstream layer rearward and then rearward and downward over the rear edge 21 and then downward at a first velocity along the rear vehicle panel 21 to form a first air curtain along the rear panel to keep the rear panel clean.     The assembly 10 has an outer air foil element 34 that, in cooperation with the inner foil element 32, directs the second airstream layer S2 rearward along the roof panel while accelerating the layer S2. The layer S2 then is directed rearward and downward over the rear edge 21 and is then directed downward along the rear panel at a higher velocity than the first layer forming a second air curtain for keeping the rear panel clean. A frame 30 attaches the assembly 10 to the vehicle 12 projecting the inner and outer air foil elements 32, 34 into the airstream to receive the first and second airstream layers S1 and S2. The mounting frame 30 provides for longitudinal and transverse adjustment of the assembly 10.

Patent CA-2077293-C (CA)
Title: Pulsed imaging, pulse width modulation scanner for a tri-level highlight color imaging system
Inventor: LOCE ROBERT P
IPC: G02F1/33
Filed: 1992-09-01
Granted: 1997-03-25
Abstract: A pulsed imaging, facet tracked, Raster Output Scanner utilizes pulse width modulation in conjunction with spatial filtering to form three exposure levels at the surface of a charged photoreceptor medium, one of the levels associated with a specific color.  This type of scanner with a nominal video rendering experiences a color line growth in the process direction.  The line growth problem is caused by a coherent optical effect. The resultant output print has bolded color lines in the process direction. Several techniques are set forth to compensate for this line growth.  In a preferred technique, the video data stream is modified by locating or positioning video pulses representing white information at the start of an associated pixel time period.  When the color pixel is imaged, it will therefore, always abut an adjoining white pulse and will be inhibited from spreading into the adjacent pixel period.  Other techniques rely upon inversion of white pulses, or separation of white pulses into two signals, each segment moved to the beginning and the end of the associated pixel period.  According to another technique, the input data stream is buffered and pixel groups examined to identify neighboring white and color signals. These signals are then either narrowed or in the case of a sequence of color signals, the lead and trail edge of the color signals are trimmed.

Granted: 2002-06-04
Abstract: A method and apparatus for evaluating the similarity of multi-mode radar pulses detected by a passive ESM receiver. The method consists of fitting a straight line to the differential phase of pairs of received signals, one signal of a pair being a currently received signal pulse and the other a previously received signal pulse, by a best least squares fit method. The slope of that straight line gives the frequency offset between the signals and the mean square error between the actual phase-time data and the straight line indicates the similarity of the signals. A second measure of the similarity of the signals can be obtained by applying statistical tests for serial correlation in the difference between the phase-time data and the straight line.

Abstract: The present invention relates to an inner pin base for a three-pole plug.  The inner pin base has a round-sectional passageway at a top portion and two channels at two sides of a bottom portion.  An upper and a lower rims of the passageway extend backward to form an upper and a lower tongue pieces, respectively, allowing a ground terminal to pass through while a projected portion on a top surface of the lower tongue piece engages with an oval hole at the end of the ground terminal passing therethrough.  The channels each has a vertical and slender slot formed at their substantially closed front end, allowing a positive or a negative terminal to pass through.  Two parallel stops extend backward from two internal sides of each vertical and slender slot and each has two vertically spaced projected portions inwardly extending toward the slender slot such that the vertically spaced projected portions of the parallel stops engage with dents formed on the positive and/or the negative terminals when the terminals are separately inserted through the vertical and slender slots. In this manner, the inner pin base allows convenient assembly of the terminals and provides considerable strength to hold the assembled terminals so that the inner pin base along with the assembled terminals may be directly positioned in a mold for injection molding to form a finished three-pole plug.

Title: Methods and apparatus for routing packets in packet transmission networks
Inventor: CIDON ISRAEL
IPC: H04L12/56
Filed: 1993-04-20
Granted: 1999-02-16
Abstract: A  packet  communications  system  provides  for point-to-point packet routing and broadcast packet routing to limited subsets  of  nodes in  the  network,  using  a routing field  in  the  packet  header which is processed according to two different protocols.  A third protocol is provided in which a packet can be broadcast to the limited subset even when launched from  a node  which  is  not  a member  of the subset.  The routing field includes a first portion which  contains  the  route labels  necessary  to deliver  the  packet  to  the  broadcast subset.  A second portion of the routing field contains the broadcast subset identifier which can then be used to deliver the packet to all of the members of the broadcast subset.  Provision is made  to  backtrack  deliver  the  packet to the last node identified before the broadcast subset if that  last  node is itself a member of the subset.

Granted: 2001-03-20
Abstract: 2095811 9307597 PCTABS00021 The present invention provides a circuit breaker control  arrangement that is reliable, accurate and cost-effective to manufacture,  install and maintain. This circuit breaker arrangement also  provides increased modularity by alleviating the need for installing wires to connect each circuit breaker with the control station.  The present invention uses circuit breakers (12) that contain  internal control technology for interrupting and establishing an  associated current path. At least one coded signal designates each  circuit breaker, and a communication bus (30) carries these coded  signals to each circuit breaker. Decoding technology (55) located on each circuit breaker determines whether the coded signal  corresponds to that circuit breaker. If the coded signal does  correspond to that circuit breaker, then the decoding technology responds  by sending the appropriate response signal over the  communication bus, and the circuit breaker's internal control technology  either interrupts or establishes the associated current path.
