Patent CA-2332851-A1 (CA)
Title: Personalized time-shifted programming
Inventor: RAJASEKHARAN AJIT
IPC: H04N21/432
Filed: 1999-04-06
Abstract: A method and apparatus for personalized time-shifted programming. Digital content is retrieved, for example, from a digital library (110). Once retrieved, the content is stored locally, for example, on a personal computer (120). The locally stored content is transferred, in whole or in part, to a playback device (125) that allows a user to listen to the content of the playback device. In one embodiment, the user may designate portions of a playback time provided by the playback device (125) to various selections. For example, with a playback device that provides two hours of content, a user may wish to listen to one half hour of news, one half hour of a series and one hour of an book. Thus, the user may partition one quarter of playback time to each of news and the series and one half of the playback time to the book. In one embodiment, the present invention provides different automatic update techniques for the playback device (125) that may be selected by the user based on how the content is to be used. For example, the news portion may be one half hour of the most recent news available from a particular source. The series may be the most recent episode in the series, whether or not the user has listened to other stored episodes. The book portion may provide one hour of the book from the most recent stopping place each time the playback device (125) is coupled to the library retrieval device (120).

Title: High and medium voltage circuit breaker with double movement comprising a blower tube guided in translation
Inventor: PERRET MICHEL
IPC: H01H33/90
Filed: 1999-06-07
Abstract: The invention concerns a circuit breaker comprising inside an interrupter chamber, a hollow arcing contact (3B) and an arcing contact in the form of a rod (5B) inserted in said hollow contact (3B) along an axial direction (A) when the circuit breaker is closed, and a blower tube (9) which is coaxial and integral with the hollow arcing (3B) and has a tube throat (9A) traversed by the rod-shaped arcing contact (5B), the hollow arcing contact (3B) and the blower tube (9) and the rod-shaped arcing contact (5B) being displaced along the axial direction (A) in opposite directions when the circuit breaker is opened. The invention is characterised in that the blower tube (9) is guided in translation along the rod-shaped arcing contact (5B) when the two arcing contacts (3B, 5B) move in opposite directions, thereby reducing the risk of contact or friction of the tube throat (9A) on the rod-shaped contact (5B), thus increasing the circuit breaker interrupting capacity.

Title: Spread spectrum interference canceler system and method
Inventor: SCHILLING DONALD L
IPC: H04B1/707
Filed: 1995-07-05
Abstract: A spread-spectrum CDMA interference canceler for reducing interference in a DS/CDMA receiver having N chip-code channels. The interference canceler includes a plurality of correlators, a plurality of spread-spectrum-processi ng circuits, subtracting circuits, and channel correlators. Using a plurality o f chip- code signals generated from chip codeword signal generators, the correlators despreads the spread-spectrum CDMA signal as a plurality of despread signals . The plurality of spread-spectrum-processing circuits uses a timed version of  the plurality of chip-code signals generated from the delay devices, for spread- spectrum processing the plurality of despread signals. For recovering a code channel using an i th chip-code-signal, the subtracting circuits subtracts from the spread-spectrum CDMA signal, each of the N-1 spread-spectrum-processed- despread signals thereby generating a subtracted signal. The channel- correlator despreads the subtracted signal.

Title: Apparatus, method and system for providing a default mode for authentication failures in mobile telecommunication networks
Inventor: AGARWAL ANJANA
IPC: H04M3/00
Filed: 2001-04-17
Abstract: An apparatus, method and system are disclosed for providing a default mode for authentication failures in a mobile telecommunication network. The system includes an authentication center (typically co-located within a home location register), an adjunct network entity, and an originating mobile switching center. The home location register generally stores information pertaining to a mobile unit, such as a cellular or PCS mobile telephone. The adjunct network entity contains one or more application nodes, such as an announcement application node for providing an announcement on a call leg to the mobile unit. When the network has been accessed by a mobile unit through a call leg, the originating mobile switching center is configured to perform an authentication procedure. The originating mobile switching center further is configured, when the authentication procedure has resulted in an authentication failure, to receive a message from the authentication center to deny the mobile unit access to the network, to terminate a communication session with the mobile unit, and to route the call leg to the announcement application node for the provision of an announcement on the call leg to the mobile unit. Following such an announcement, the originating switching center is also configured to route the call leg to a customer service center, for example, to reprogram the mobile unit.

Title: Tangential separating device for solid matter
Inventor: HEINZ ROBERT
IPC: B03B5/28
Filed: 1999-08-25
Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A  rotationally symmetrical flocculation/flow reactor (20) is provided with outlets in the lower part thereof and is arranged in a separating tank (12). At least one suspension inlet (24) extends eccentrically into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor (20) via the suspension inlet (24). A circular flow is thus created which drains off from the flocculation reactor (20) downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells (44) which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank (12). In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.
