Title: Ad hoc telecommunications network management and routing
Inventor: TAIB RONNIE BERNARD FRANCIS
IPC: H04L12/24
Filed: 2001-09-10
Abstract: An ad hoc telecommunications network comprises a plurality of mobile devices, cached data being distributed amongst the devices. A manager device is elected for example based on highest compared received signal strength amongst the devices to manage the distributed data. The manager election can be dynamically up-dated to compensate for changes in the network parameters, for example devices entering or leaving the network, or physical relocation of the devices within the network. In addition, the ad hoc network can communicate with a fixed infrastructure, the fixed infrastructure maintaining a table identifying a gateway device for direct communication with the fixed infrastructure, allowing communication with a mobile device within the ad hoc network. Yet further the ad hoc network can provide a communications route between two remote fixed infrastructures. <IMAGE>

Patent CA-2017371-A1 (CA)
Inventor: KARDOS PETER
IPC: F16K15/10
Filed: 1990-05-23
Abstract: ABSTRACT OF THE INVENTION This invention relates to a flapper check valve having a valve housing which has at least one outlet opening.  A valve backer plate having a plurality of arcuate backer through holes is positioned generally parallel to a valve port plate having a plurality of arcuate port through holes. The valve port plate and valve backer plate are sealably secured with respect to the valve housing.  In an open position of the flapper check valve, the backer through holes are in communication with the port through holes.  At least one peripheral spacer/hermetic seal is positioned at a generally peripheral location relative to the valve port plate.  Upon combustion within the combustion chamber, the flapper check valve prevents fluid/gas backflow in a direction from the valve backer plate to the valve port plate.  At least one flat central spacer is positioned at a generally central location relative to the valve port plate and the valve backer plate.  A plurality of inner spacer/guide pins are positioned on an interior surface of the valve port plate.  The inner spacer/guide pins provide sufficient support to the valve backer plate whereby the valve backer plate can have a reduced thickness and still resist deflection when the valve backer plate is subjected to relatively high pressures from within the valve housing during a combustion cycle within the combustion chamber.

Abstract: Abstract of the Disclosure An improved actuating device for school bus safety unit, such as crossing arms and the like, which includes an arrangement for driving and controlling the crossing arm in a continuous predetermined arcuate path of movement, with the safety device being moved continuously back and forth in a sweeping motion that provides a moving barrier in areas adjacent the school bus where children  may  be  placed  in  an  unsafe  situation,  such  as immediately adjacent the front bumper of the bus which is outside of the normal line of vision of the school bus operator.  In one embodiment, an extendable line is anchored to the bus at one or both ends, and an intermediate portion of the line is engaged by the moving safety unit,  whereby the line itself creates a changing barrier as the safety unit sweeps through its path of movement. A warning arrangement may also be provided to generate a warning signal to the school bus operator whenever the sweeping movement of the crossing arm is stopped or slowed, such as when a child is positioned in the path of movement of the crossing arm.

Patent CA-2023484-A1 (CA)
IPC: G21C1/00
Filed: 1990-08-17
Abstract: A nuclear reactor using gas as a primary coolant and liquid  as  a  moderator  and/or  reflector.   Gas  coolant  flows through inlet passages around the outlet plenum to a distributor plate.  The gas is directed between fuel element housing thimbles and fuel elements therein, through the fuel elements, and into the reactor outlet plenum.  Fins on the thimble housings conduct heat to the gas from a liquid moderator circulating in the core. The use of a liquid moderator enhances safety, allows the fissile material and reactor mass to be reduced and eliminates problems associated with cooling of a solid moderator.

Abstract: An ultrasonic air-in-line detection system for use in detecting air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed in which a self-test procedure is periodically used to ensure that any faults in the ultrasonic air-in-line detector which do not fail safe are automatically detected.  After a pumping cycle is completed, if the ultrasonic air-in-line detector indicates that there is fluid in the fluid line at the location of the ultrasonic sensor, the operating frequency of the transmitting ultrasonic transducer is changed to a non-resonant frequency for the self-test procedure.  If the ultrasonic  air-in-line  detector  still  produces  a  signal indicating that there is fluid in the line, this indicates that there is a failure in the ultrasonic detector and a fault is indicated and the system is shut down.
