Patent CA-2295386-A1 (CA)
Title: System and method for minimizing slag carryover during the production of steel
Inventor: STELTS ELIZABETH A
IPC: G01J5/00
Filed: 2000-01-13
Abstract: A system and method for detecting molten slag in a tap stream between a steel making vessel such as a basic oxygen furnace (BOF) and corresponding ladle. An infrared (IR) imaging or detecting device (s) is used to image/view the BOF-to-ladle tap stream, the stream transmitting energy indicative of whether molten steel and/or slag is in the stream at a given time.      Gray scale analysis is performed on pixels viewed from the tap stream to determine the number of steel pixels and the number of slag pixels in the stream at a given time. When the ratio or percentage of slag pixels exceeds a predetermined value or amount, an alarm may be actuated to cause an operator to tilt the converter upward to stop tapping, or the converter may be automatically tilted upward to stop tapping.

Title: Control system for vehicle lighting
Inventor: BRANDT BRIAN E
IPC: B60Q1/46
Filed: 2000-01-25
Abstract: A lighting system for a towed off-highway vehicle has a left and right hazard warning lamps that flash in unison when the vehicle is not turning. When the vehicle is turning, the hazard warning lamp on the side of the turn flashes, while the other hazard warning lamp is illuminated steadily. Left and right turn indicator lamps are operated by a control circuit that receives signals which operate the hazard warning lamps. The control circuit responds to those signals by rendering the turn indicator lamps inactive when the vehicle is not turning, and operates the left and right turn indicator lamps in the same manner as the left and right hazard warning lamps, respectively, when the vehicle is turning.

Title: Method and apparatus for dynamically exchanging data among participants to a conference call
Inventor: BAUER ERIC JONATHAN
IPC: H04M11/00
Filed: 2000-06-01
Abstract: A media exchange monitor is disclosed that selectively (i) introduces a mixer into a two-party call when the two-party call becomes a conference call (ad-hoc conference), and (ii) removes the mixer when one or more conference call participants drop out, leaving only two participants behind. When a party to a two-party call requests to convert the call into a conference call, the packet telephony system responds to the conference call request by connecting a mixer to service the conference call between the parties. When parties drops out of a conference call, leaving only two parties behind, the mixer is removed from the conference call. In one implementation, the mixer is removed from the conference call only if the two remaining parties can exchange media directly. When the media connection among the parties must be changed to introduce or remove the mixer, the media exchange monitor achieves the desired connectivity by initially querying the parties for their capabilities. Thereafter, the media exchange monitor instructs the parties to establish a direct connection for a two-party call or to connect to the mixer for a conference call. The media exchange monitor processes the results of the capability query to select a compatible compression algorithm.

Abstract: Method of detecting obstructions encountered by a motorized door. The method includes providing a signal processor with one or more signals indicative of a predetermined door trajectory profile for at least a segment of a stroke of the door, the door trajectory profile providing an ideal speed and/or position versus an elapsed time since a beginning of the segment of the stroke. A door position signal from a position encoder for the door is received into the signal processor. The method includes generating one or more signals indicative of the velocity and/or position of the door from the door position signal and generating a trajectory discrepancy signal based on the velocity and/or position in relation to the ideal speed and/or position.      A motor control signal is generated based on the trajectory discrepancy signal and the motor control signal is connected to motor control circuits connected to drive the motor for the door. The method further includes performing one or more tests on either the trajectory discrepancy, the velocity of the door or the position of the door to determine whether the door has encountered an obstruction, in which case an obstruction detection signal is generated. The obstruction detection signal is for stopping the door.
