Patent CA-2092744-C (CA)
Title: Spectrum recovery apparatus and method therefor
Inventor: VATT GREGORY BARTON
IPC: H04B7/185
Filed: 1993-03-26
Granted: 2001-12-04
Abstract: A controller operates with a cellular communication system that transmits primary communications. The controller recovers a portion of the spectrum assigned to the primary communications for reuse in transmitting secondary communications. The primary communications' cells move in a predictable manner relative to a site at which the controller is located. The controller monitors primary communications to determine the current active cell.      The identities of past active cells are saved so that a historical sequence of active cells is available. A map defining the relative orientation of cells is used with the historical sequence information to predict tracks through newly entered active cells. Based on this prediction, a recoverable cell is selected.      Communication link parameters of the recoverable cell are used for secondary communications. The identity of the recoverable cell changes in response to changes in the identity of the active cell.

Granted: 2004-01-13
Abstract: An engine ignition and control system for an internal combustion engine. The system includes an ignition transformer mounted to a spark plug and adapted to rapidly re-fire the spark plug during a combustion cycle enabling the performance of various engine diagnostic procedures. A controller provides a signal to an ignition circuit which causes the transformer to charge for ignition and subsequently charge for performing diagnostics. The system also includes a diagnostic circuit, connected to the transformer, which can detect the occurrence of an electrical discharge across the spark plug electrodes as a result of one of the diagnostic charges. The detections circuit either outputs a signal to the controller or omits the signal to the controller. This allows the controller to diagnose conditions within the combustion cylinder.

Granted: 2001-08-28
Abstract: A more economical, stable, non-shrinking cellular concrete is provided by the addition of cementitious or non-cementitious fines to a cellular concrete mix. The improved cellular concrete is attained by reducing the amount of cement and replacing it with an equal amount of cementitious or non-cimentitious fines.

Granted: 1998-09-01
Abstract: The apparatus of the present invention may be implemented in software which performs the following steps: calculating a desired air velocity in the exhaust duct from a first input signal representative of the side of a variable sash opening and a first user defined setpoint representative of a desired face velocity; comparing successive values of the desired air velocity to determine any absolute and percent change therebetween; comparing the absolute change to a user defined reset deadband value; producing output signals, responsive to a second input signal representative of the measured air velocity in the exhaust duct and the second comparing step, for input to the fan so as to force the measured air velocity toward the desired air velocity. The production of the output signal is accomplished by adaptive, feedforward techniques when the absolute change is greater than the reset deadband and is accomplished by proportional/integral techniques when the absolute change is less than the reset deadband.  A timer is provided to lockout the production of output signals produced by employing proportional/integral techniques for a predetermined period of time after an output signal is produced by employing adaptive, feedforward techniques.
