Title: Constellation matching system and method
Inventor: WELLS JOHN D
IPC: G06T3/00
Filed: 1991-11-06
Granted: 1994-09-20
Abstract: CONSTELLATION MATCHING SYSTEM AND METHOD                   ABSTRACT OF THE DISCLOSURE      A system  (10)  and method for matching a set of detected points (26) to a reference constellation (20). A  programmable  processor   (14)   receives  detected coordinate locations from a sensor (16) and reference coordinate locations from a reference storage device (12).     The  processor  (14)  performs  a  coordinate transformation from the reference coordinate frame to the detected  coordinate  frame  and  contructs  a  table  of possible matches.  Potential matches are found from the possible matches which have their difference vectors below a predefined threshold.  These possible matches are then placed in a match matrix histogram (30) which is further refined to eliminate all but the best matches. The final matching then may be used to find a particular aimpoint (24) in the detected constellation (26).
Patent CA-2060433-C (CA)
Inventor: NISHIKAWA SEIITHIROU
IPC: F01N3/10
Filed: 1992-01-31
Granted: 1999-11-02
Abstract: A control apparatus for speedily warming up a catalyst disposed within an exhaust pipe connected to an internal combustion engine. The control apparatus first determines a fuel injection amount and an ignition timing of the engine on the basis of an engine operating condition such as an intake air pressure of the engine and a rotational speed of the engine. The control apparatus is also responsive to temperature information of the catalyst for adjusting the fuel injection amount and the ignition timing in accordance with the catalyst temperature information.      When the catalyst temperature does not reach the effectively emission-purifying temperature, the control apparatus alternately adjusts the fuel injection amount to a rich side and a lean side and further intermittently retards the ignition timing. This injection and ignition control operation allows acceleration of the warming-up of the catalyst to suppress the deterioration of the emissions from the engine.

Title: System and method for introducing meter sensor hysteresis
Inventor: SWANSON SCOTT C
IPC: G01R21/133
Filed: 1992-08-06
Granted: 2001-04-10
Abstract: A method and system is disclosed for accurate remote reading of an electricity meter. An optical detection arrangement, including a light emitter and sensor, have positioned in the light path therebetween a cutout portion of the meter shaft. Rotation of the shaft affects the amount of light passed to the sensor.      Registration errors which may occur in a linear transition operating range are avoided by provision of detector threshold hysteresis. A microprocessor sets timing pulses for emitter energization, establishes a detection period of uniform length of time for each energizing pulse and produces, during each detection period, a digital signal having a logic level indicative of the presence or absence of light transmitted to said sensor, whereby a correlation between light transitions and power usage can be made.      Accuracy of detection is improved under microprocessor control by introducing hysteresis in the delay between emitter energization and detection, in the voltage threshold in a comparator connected to the detection circuit, or in emitter energization driving current.     The hysteresis is determined in accordance with the memorized state of the last previous detected signal.

Filed: 1991-11-25
Granted: 1997-06-10
Abstract: An automated guided vehicle (AGV) control system which is downward compatible with existing guidewire systems pro-viding both guidewire navigation and communication and autonomous navigation and guidance and wireless communication bet-tween a central controller and each vehicle. Autonomous vehicle navigation comprises travel over paths marked by update mark-ers which may be spaced well apart, such as fifty feet. Redundant measurement capability comprising inputs from linear travel encoders from the vehicle's drive wheels, position measurements from the update markers, and bearing measurements from a novel angular rate sensing apparatus, in combination with the use of a Kalman filter, allows correction for navigation and guid-ance errors caused by such factors as angular rate sensor drift, wear, temperature changes, aging, and early miscalibration during vehicle operation. The control system comprises high frequency two-way data transmission and reception capability over the guidewires and via wireless communications. The same data rates and message formats are used in both communications sys-tems.

Title: Method & apparatus for manufacture of plastic refrigerator liners
Inventor: WILLIAMS STEPHEN G
IPC: F25D23/06
Filed: 1993-05-10
Granted: 2004-07-13
Abstract: Plaques are formed on the sidewalls of the liner in a refrigerator to reduce thermally induced bowing of the cabinet.        The plaques may consist of indentations in the liner, which in a preferred form are rectangular, or arrays of multiplanar indentations. The plaques provide increased surface area in the liner to permit thermal expansion without bowing, and also increase the structural rigidity of the liner to resist bowing.        Thermal bowing is encountered where there are long unsupported wall surfaces and high temperature gradients across the wall.        Therefore the plaques are very effective in the freezer compartment of a side-by-side refrigerator, where bowing can be severe in the absence of the disclosed corrective measure.

Title: Method for making 3.alpha.-hydroxy, 3.beta.-substituted-pregnanes
Inventor: TAHIR SYED H
IPC: C07J17/00
Filed: 1993-02-22
Granted: 2004-08-10
Abstract: This invention provides a simplified method for converting pregnan-3,2.0-dione compounds to 3.alpha.-hydroxy,3.beta.-substituted-pregnanes. By selective use of reagents the unprotected dione is converted chemoselectively and diastereoselectively into a 3(R)-pregnan-3-spiro-2'oxirane-20-one intermediate. This intermediate can then be converted regio-selectively by a second set of reactions to the 3.alpha.-hydroxy,3.beta.-substituted-20-one form, which can be further modified at the 20-keto position. Through this method, each ketone group is independently treated. By modifying the ketones one at a time, one can obtain the desired stereo-specificity at each site.

Title: Inertia latch assembly for seat hinge mechanism
Inventor: WHALEN JOHN F
IPC: B60N2/20
Filed: 1994-11-29
Granted: 2004-11-09
Abstract: An inertia-sensitive seat hinge mechanism allows rotation of a seatback relative to a seat bottom under normal use conditions and yet prevents such rotation in response to deceleration forces exceeding a predetermined threshold level.  The seat hinge mechanism includes a lower hinge member connected to the seat bottom and an upper hinge member connected to the seatback and an inertia-sensitive latch assembly. The inertia-sensitive latch assembly includes a component carried by the upper member which defines first and second stop surfaces. The first stop surface limits rotation of the upper hinge member in one direction. An inertial actuator is rotatable with respect to the upper hinge member and includes an engaging finger for engaging the second stop surface when the upper hinge member attempts to rotate in an opposite direction due to exertion of the predetermined deceleration forces thereon. The inertial actuator also includes a projection located adjacent a center of rotation. Moreover, the inertial actuator has a center of gravity spaced from the center of rotation. A release lever engages the projection to rotate the inertial actuator into a normal position against the component when the upper hinge member is fully rotated against the first stop surface. A biasing device, located on the component, biases the release lever to release the projection when the upper hinge member is rotated in the opposite direction and allows the inertial actuator to rotate by gravity if the predetermined deceleration forces are not present.

Abstract: An arrangement for selectively altering the serving of emergency serving areas.  Normally emergency serving areas are grouped and all calls for agroup are handled by teams of agents at public safety answering point (PSAP) positions.  For special emergencies such as a fire it is desirable that all traffic from one emergency service area be specially routed either to a single destination such as one PSAP position or a telephone in a fire station or to a special group of agents. This is accomplished by assigning a different routing telephone number to the emergency service number corresponding to each emergency service area and using that routing telephone number for routing calls.  The calls are routed first to a single agent position which is normally not logged in and then on a default basis to anautomatic call distributor (ACD) number for routing to a team of PSAP agents. If a special emergency occurs in one of the ESAs, then the routing for the corresponding ESN is changed either by logging on an agent to handle all calls for that ESN or by changing the default ACD number to route these calls to a different ACD or to a different telephone.  Advantageously, such an arrangement allows for a highly flexible routing under special emergency conditions without requiring a complex individual ACD routing for each ESN under normal conditions.
