Title: Method of accessing messages
Inventor: HESSION PATRICK PETER
IPC: H04M3/53
Filed: 1999-10-18
Abstract: A data terminal is used to access, via a data network, a message which is stored by a messaging system. The message has content which requires real-time playback at the terminal, such as a voice mail message. A request for the message is sent to the messaging system, and in response to receiving the request the messaging system initiates a communications call over the data network to the data terminal.  The requested message is delivered by playing the message during the call over the data network. This avoids delays in retrieving messages via FTP.

Title: Self-aligning component support system for a vehicle
Inventor: COOK ROB A
IPC: F02M35/16
Filed: 2000-02-03
Abstract: A component support system for a vehicle provides a way to firmly attach a component to a vehicle. The component support system comprises a component member adapted to attach to the component to be mounted and a support member adapted to attach to the vehicle. The component member has a first mating surface with a first channel formed thereon. The support member has a second mating surface with a second channel formed thereon. The second channel is adapted to interfit with the first channel. Because the channel configurations are non- symmetric about an axis allowing the parts to interfit in only one orientation, the component support system is self-aligning. A fastener is adapted to retain the component member against the support member when the first channel is interfitted with the second channel.

Abstract: A fishing lure retriever having a teardrop-shaped weight of lead or similarly dense material. Clipping means are attached to the weight. The weight and clipping means are coated in a thin layer of vinyl or similar resilient material. Where a fishing lure has become entangled underwater, the retriever is attached to the fishing line and permitted to descend by gravity along the line to the point of entanglement. Motion of the fishing line with the retriever in place near the entangled lure results in controlled movement of the weight near the entangled lure effecting disengagement of the lure.

Patent CA-2315867-A1 (CA)
Inventor: NELISSEN JORDI
IPC: H04L47/31
Filed: 2000-08-14
Abstract: The invention relates to a buffer acceptance method. Such a buffer acceptance method is used for deciding whether to accept incoming data (P-VCi) of a data flow in a buffer (BUF). The buffer (BUF) is dynamically shared by data of a plurality of data flows. The incoming data (P-VCi) comprises a priority (P2) out of at least two priorities (P1, P2). The method comprises the steps of associating for each data flows and to each priority at least one predetermined partial buffer threshold (PBTi2) and at least one predetermined global buffer threshold (GBTmin, GBTmax). Upon reception of the incoming data (P-VCi), its related data flow (VCi) and its priority (P2) is determined. Furthermore, a first monitoring of an actual occupation level of a partial buffer part (qi), being associated to the data flow, against the associated predetermined partial buffer threshold (PBTi2) is executed and a second monitoring of a globaR occupation level of the buffer (Q) against the predetermined global buffer threshold (GBTmin, GBTmax) being associated to the data flow (VCi) and to the priority (P2) is executed. Finally, the method comprises denying acceptance of the incoming data (P-VCi) in the event when both monitoring tests are providing a drop result i.e. the first monitoring provides a first drop result and the second monitoring provides also a second drop result.

Title: Variable output rotary power generator
Inventor: BARTEL ROGER P
IPC: H02K7/18
Filed: 1999-01-16
Abstract: The present invention is directed to a downhole apparatus for quickly generating and regulating variable output electric power by varying the alignment of a pair of axially adjacent permanent magnets (84, 82) rotating within an armature (88) having electrically conductive windings. Each of the permanent magnets (84, 82) comprises a plurality of permanent magnetic segments having circumferentially alternating magnetizations. One of the permanent magnets (82) is fixed to the drive shaft (86) and the other permanent magnet (84) is movably mounted on the drive shaft (82) to enable the alignment or misalignment, as desired, of the magnetizations of the respective magnetic segments on the pair of permanent magnets (84, 82). When the magnetizations are completely aligned, the maximum electrical power is generated in the windings of the main armature (88); conversely, when the magnetizations are completely misaligned, zero electrical power is generated.  Thus, the output power is regulated by varying the alignment of the pair of permanent magnets (84, 82), which is accomplished with a drag torque generator which creates a drag torque that is transmitted to the movable permanent magnet (84) by a torque converter.
