Title: Automatic lighting control system for a cooking cavity
Inventor: BENNETT PERRY A
IPC: H05B6/80
Filed: 2000-04-19
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.

Title: Adaptive handoff hysteresis in wireless telecommunication networks
Inventor: BRINGBY DANIEL
IPC: H04W36/30
Filed: 1998-12-08
Abstract: A method of setting the appropriate hysteresis for cells in a wireless telecommunication network in order to reduce the rate of oscillating handoffs arising from a routine mobile station handoff from an originating cell to a neighboring cell. The method includes measuring the received signal strength in the originating cell and the received signal strength of at least one neighboring cell.  The hysteresis is calculated by applying a statistical operation, such as the standard deviation, to at least one of the received signal strengths. Alternatively, the hysteresis calculation may include the handoff oscillation rate. The calculated hysteresis value may be presented to the operator for manual adjustment or may be input into self-configuring cells for the dynamic adjustment of hysteresis levels to improve the network operating performance.

Patent CA-2331477-A1 (CA)
Inventor: ROSE RALPH E
IPC: G05B17/02
Filed: 2001-01-19
Abstract: A technique is disclosed for adjusting the parameters in the state equations governing the behavior of a system of state variables. By proper adjustment of the parameters in the state equations, the behavior of the state variables can be modified so that the system behaves as desired. The key to using this technique is the development of the concept of derivative variables. The derivative variables are variables processed by their own set of state equations derived from the original set of state equations. For each state variable in the original system and each parameter whose value is to -be adjust there exist a unique derivative variable. The value of the each derivative variable represents the instantaneous value of the derivative of a particular ordinary state variable with a particular parameter. Two matrix techniques are disclosed that can be used to increase the training rate.
