Patent CA-2134018-A1 (CA)
Title: Highly dynamic destination-sequenced destination vector routing for mobile computers
Inventor: PERKINS CHARLES E
IPC: H04L12/56
Filed: 1994-10-21
Abstract: Packets are transmitted between stations of an ad-hoc network of mobile stations by using routing tables which are stored at each station of the network. Routing information is broadcast or multicast according to three schedules;  upon demand to show new routes, periodically to show recently changed routes, and less often to provide a complete dump of all known routes. A new route will trigger immediate re-broadcast so that this information is quickly disseminated. A new route is defined to be one with a better metric or a metric of infinity. A metric of infinity indicates a broken link; i.e., a particular destination is no longer reachable and thus all other destinations depending upon the newly unreachable destination are themselves unreachable. Periodically, routes are advertised.  This advertisement serves primarily in most cases to notify all neighbors that everything they have stored is still correct regarding the broadcasting Mobile Host. On rarer occasions when the routing topology changes, the demand nature of the incremental update displaces the periodic transmission until an update interval transpires. In order to damp out oscillations, data is kept about how often the routes change. Based on this data, a decision may be made to delay advertising routes which are about to change soon, thus damping oscillations of the route tables.

Title: Device for adjusting the length of a support
Inventor: ONO TATSUO
IPC: E04G25/08
Filed: 1994-11-16
Abstract: A device for adjusting the length of a support composed of an outer tube and an inner tube slidably insert-ed in the outer tube, includes an opening extending radially through the outer tube, a spacer radially movably received in the opening and confronted with an outer surface of the inner tube, a housing mounted on the outer tube in confront-ing relation to the opening, and a wedge slidably inserted in the housing to force the spacer radially inwardly against the inner tube. With this construction, the inner tube and the outer tube can be firmly fastened together with a great tightening force without damaging the inner tube. A stopper pivoted on the wedge and normally urged upward by a spring is able to preclude an unintended omission of driving the wedge or an incompletely driven or tightened condition of the wedge.

Title: Method of manufacturing moulded articles from cellular plastic, and a mould for carrying out the method
Inventor: BEHL ERHARD KONRAD
IPC: B29C35/06
Filed: 1993-08-27
Abstract: The method proposed for manufacturing moulded articles from cellular plastic is designed so that production of the mouldings requires little vacuum and steam and the mouldings have a very low moisture content.  This is achieved by using a mould whose cavity walls are made of poorly heat-conducting material or have a suitable low-conducting coating.  The mould cavity is evacuated, the expandable granulated material is fed under pressure into the evacuated mould and, when the cavity is filled, steam passed into the evacuated mould.  The steam is switched off and the mould cavity again evacuated, the vacuum thus produced being maintained during the stabilization phase.  After the stabilization phase, the mould is opened and the moulding ejected using pressure.

Abstract: An apparatus for thermal protection of an electric motor  is  provided,  including  a  monitoring  device  for generating a signal representative of the current in a conductor supplying electrical power to the electric motor. A control circuit processes the current signal and utilizes the  processed  signal  and  motor  thermal  parameters, including the thermal resistance and thermal capacitance of the  rotor,  to  generate  signals  representative  of  the temperature of at least the rotor.  A comparator circuit, which may be part of the control circuit, compares the temperature  signals  to  reference  maximum  temperature signals and produces a control signal when the temperature signals  and reference  signals  satisfy  a  predetermined relationship.   The control signal may be applied to a contactor to interrupt current to the motor.  A method for thermal protection of an electric motor is also provided, including thermal modeling of the rotor temperature.

Title: Telecommunication device and method for interactive voice and data
Inventor: KOSOWSKY RICHARD P
IPC: H04M11/06
Filed: 1994-03-09
Abstract: A telecommunication device permits mixed voice communication  and data communication during a single telephone call. The device switches freely between bidirectional voice communication and bidirectional data communication as required by the data to be communicated. The dynamic switching between voice communication and data communication is arranged so that voice communication is minimally interrupted.  Data communication using the device includes creation, transmission,  reception, storage, retrieval, display and use of data messages such as address and telephone number records. The device is inexpensive to produce and uses existing standards for signalling by telecommunications equipment.  A complete interactive voice and data (IVD) system automatically performs data communication between IVD subscriber systems, or between an IVD subscriber system and an IVD host system.  Further, in conjunction with a standard IVR, a complete IVR/IVD system automatically performs data communication with IVD subscriber systems and IVR voice communications with non-IVD subscriber systems.

Title: Contoured landing surface systems and method of making thereof
Inventor: ROBINSON TROY
IPC: A63B6/02
Filed: 1994-06-30
Abstract: This invention is a contoured landing surface system. The system matches landing surfaces or pit density to the force generated by an athlete's descending body to cushion the athlete's fall based on air displacement rather than foam characteristics. The system is designed to compensate for variables such as velocity, mass, and surface area at the point of impact by utilizing a multilayered structure (10) each layer (12)(14)(16) having a plurality of patterned ridges thereon and a network of air channels therebetween. The ridges (16) and air channels (20) of adjacent layers extend perpendicular to the ridges (16) and air channels (20) of each other. Preferably, the landing surface is constructed using layers of foam having the same density.
