Title: Automatic lighting control system for a cooking cavity
Inventor: BENNETT PERRY A
IPC: F24C7/08
Filed: 2000-04-19
Granted: 2005-10-04
Abstract: A cooking appliance includes an oven cavity having an associated access door provided with a cavity viewing window, a control panel for setting both a desired cooking function and a heat source operating time period, and a light for illuminating the oven cavity of the appliance. The light is controlled so as to be automatically activated prior to the expiration of the set time period for the selected cooking operation in order to bring the attention of the user to viewing the progress of the cooking operation without unnecessarily opening the oven cavity door.      If, after viewing the food being cooked, it is determined that further cooking time is warranted, then the process of adding additional cooking time will function to re-set the automatic light activating feature of the invention. In addition, if the user opens the door following activation of the cavity light but prior to the expiration for the established cooking time period, then the light will preferably remain on until after the cooking function is completed. Various provisions are also made for de-activating the light after the cooking operation is completed. Furthermore, if the light is manually activated, the light will automatically be de-activated upon opening and closing of the door.

Patent CA-2325185-C (CA)
Inventor: MAZZIOTTI PHILIP J
IPC: F16D13/75
Filed: 2000-11-07
Granted: 2005-04-26
Abstract: The externally threaded surface of a clutch adjusting ring is provided with circumferentially spaced friction-enhancing plugs, preferably formed of nylon. The plugs are friction fit into bores located between the first and last threads of the externally threaded surface. The nylon plugs are slightly longer than their bores and, therefore, the top surfaces of the plugs extend slightly beyond the externally threaded surface. As the externally threaded surface of the ring is threaded into the cover, the corresponding internally threaded surface of the cover cuts through the radially extending plugs located in the threads of the ring. The plugs fractionally grip the cover thereby preventing, or greatly reducing, the amount of play in the adjusting ring, yet allowing the ring to be readily turned manually. In alternate embodiments, the friction-enhancing plugs are provided just on the corresponding threaded surface of the clutch cover, or on both the internally threaded surface of the clutch cover and the externally threaded surface of the clutch adjusting ring.

Title: Network for multi-lateration with circularly polarized antenna
Inventor: BOYD ROBERT W
IPC: G06K17/00
Filed: 1999-09-02
Granted: 2008-11-18
Abstract: A distributed radio geo-location and tracking system has a distributed subsystem architecture that distributes its processing workload over a plurality of information handling and processing subsystems.  For maximum detection capability, each of a plurality of tag emission receivers (10) is equipped with a circularly polarized, omnidirectional antenna (Figures 3-5), to provide hemispherical coverage. The receivers are coupled to a partitioned plurality of detection processors (50), that are coupled via distributed association processors (60) to multiple location processors (70). Each detection processor demodulates and time stamps received energy correlated to known spreading codes of the tags, to associate received energy with only one tag. It transmits a message containing this information over a communication framework to an association processor.  The computational load is equitably distributed by a flow control mechanism among available association processors, with all receptions of a single tag transmission being directed to the same association processor. An association processor organizes received messages by tag and time-of-arrival (TOA), and transmits association reports over an association communication process of the communication framework to one of plural distributed location processors. A location processor determines the geographical locations of tags using the TOA  information in the association reports.

Patent CA-2363462-C (CA)
Inventor: WOOD JAMES A
IPC: B60T8/18
Filed: 1998-06-08
Granted: 2002-12-10
Abstract: An electronic load weigh device is used with a railcar truck control unit. A  relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A  second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves. The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.
