Patent CA-2328913-A1 (CA)
Inventor: ZETMEIR KARL D
IPC: G06Q30/00
Filed: 1999-04-14
Abstract: A telephone call management computer program that provides both call management features and long distance savings for telephone consumers and marketing and advertising services for sponsor companies that wish to advertise to the consumer is disclosed. The call management program is initially stored on a host computer (12) and is then downloaded upon request to user computers (22) along with advertisement banners selected by the sponsor companies. When used, the program automatically front-loads a long distance carrier's PIC code in front of all long distance calls made from theuser computers to permit consumers to automatically make long distance phone calls at discounted rates without memorizing numerous PIC codes and without continually shopping for the best long distance rate. The program also provides many enhanced telephone calling options and displays the banners and other advertising directly on the user computers (22) while the consumers use the program.

Title: Video encoder and encoding method with buffer control
Inventor: EIFRIG ROBERT O
IPC: H04N7/50
Filed: 1999-05-28
Abstract: A technique is provided for enabling data, such as video, to be broadcast using a push dataflow scenario without causing a data rate buffer (32) for the pushed data at a decoder (30) to overflow or underflow. At an encoder (20), data are encoded for communication to the decoder (30) to provide an output bitstream. The data rate buffer (32) of the decoder is simulated at the encoder (22). The simulation is used to control the output bitstream to preclude overflow or underflow of the decoder buffer (32). For example, a complementary encoder buffer (22), which operates in a manner opposite to the decoder buffer (32), can be monitored and inverted to provide the simulation.  Various different techniques are disclosed for controlling the amount of data produced at the encoder to maintain the data within the confines of the decoder buffer (32).

Patent CA-2336518-A1 (CA)
Inventor: OPFER JOHN C
IPC: H01H33/02
Filed: 2001-03-01
Abstract: A multi-pole protective device and system for electrical power transmission and distribution systems is provided that operates a multi-pole tripping system at ground level from a line-potential tripping device contained within each pole of the multi-pole system. The system includes multiple pole-unit assemblies each of which is responsive to sensed overcurrents to provide a tripping signal. Each of the pole-unit assemblies is totally self--contained and generates a tripping signal in response to overcurrent conditions to operate a ground-potential operating mechanism. In one arrangement, the pole units each include an internal line-potential tripping arrangement that communicates a trip signal to a ground-potential operating mechanism of the pole unit and associated pole units of the protective device arrangement. Each pole unit also includes an interrupter operated by the ground--potential operating mechanism to open the interrupter. In such an arrangement, the pole units are mechanically independent of each other providing flexibility of location and ease of installation. Thus, the only interconnections between the pole units is the communication of the trip signal via electrical lines or the like. In a preferred arrangement, the line-potential tripping arrangement includes an insulated member that is moved to transmit the trip signal from line potential to ground potential. Also in a preferred arrangement, the movement of the insulated member generates a trip signal to operate the operating mechanism of the pole unit and associated pole units. In an alternate arrangement, the movement of the insulated member controls an electrical circuit to provide tripping signals to the pole units. In a particular arrangement, the operating mechanism of each pole unit is individually recharged manually via a tool affixed to a hot stick or the like. The recharging of the operating mechanism of each pole unit functions to close the interrupter thereof. In a particular arrangement, the line--potential tripping arrangement of the pole unit is also reset during the recharging so as to be ready for tripping and operating the pole unit.
