IPC: H04L12/56

Abstract: A method for use in a high-speed virtual circuit digital network for resizing windows of virtual circuits in nodes of the network. The resizing of a virtual circuit's window is initiated by an input router at an edge of the digital network. When the input router determines that resizing is necessary, it sends a first congestion control message to the nodes through which the virtual circuit passes. If the message indicates a larger window, the node receiving the message determines what size window it can provide and sends the message with that window size on to the nextnode. An output router at the other edge of the digital network receives the message, sets the window size based on the message as altered by the nodes, and returns asecond message with the final window size via the nodes. On receipt of the second message, the nodes alter their windows and the input router sends cells as permitted by the new window. Included in the method are novel techniques for determining the ideal window size for a virtual circuit, for determining at the input router when a change in window size is necessary, and for determining the size of the window in the nodes.

Patent CA-2048529-A1 (CA)
Inventor: D'ANDRADE BRUCE M
IPC: B05B9/08
Filed: 1991-08-07
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is directed toward a toy water gun which is operated by selectively releasing water from a water reservoir that is pressurized with air.  The present invention is a one piece device formed in the general shape of a gun that has a manually operated air pump in-corporated into the design.  The air pump pressurized a water reservoir and consequently pressurizes any water found therein.  The pressurized water has an avenue of release that is regulated by the trigger mechanism of the in-vention.  When no force is applied to the trig-ger, the pressurized water is held at bay with no means of release.  When force is applied to the trigger, water is released from the pressurized container and is channeled through a narrow nozzle.  The escape of the pressurized water through the narrow nozzle creates a stream of propelled water that lasts as long as the trigger is engaged or until the pressure of the water equals the ambient air.

Abstract: In a microcellular cordless telephone network, radio speech channels are divided into several channel groups such that no intermodulation products occur among the channels of each group.  In each microcell is located a base unit to which one of the channel groups is dynamically assigned.  To achieve the channel assignment each base unit generates priority values of the channel groups as representations of usage of the channel groups, constantly updates them through a statistical process and assigns one of the channel groups having a maximum priority value to the base unit.

Abstract: A separator which can be used for separating water from an air/water mixture in an aircraft where the air is to be supplied to electronics equipment comprises a chamber containing a generally tangential inlet tube through which a mixture is supplied to a curved side wall section of the chamber to separate water from the air by centrifugal action. The efficiency of the unit is improved either by moving the filter unit away from the centre of the chamber or by providing a guide plate between the filter unit and the curved side wall on which the water coalesces. In this latter case, the filter unit can also be offset from the centre of the chamber to give even greater improvement and efficiency.
