Abstract: Speech is transmitted between a base station (BTS) and a TRAU by converting a speech signal into a parameter group which is inserted in a traffic frame which is transmitted as a packet comprising a header and a payload. In accordance with the invention, the payload is formed of the contents of several traffic frames until the payload is essentially full, and a packet is sent to the destination via the transmission network. At the destination the traffic frames are separated from the payload of the received packets and they are passed to a speech decoder. The packing of packets full can be started about a second after the beginning of the connection and after pauses, in which case the ending of a pause is transmitted to the listener as fast as possible.

Patent CA-2276926-A1 (CA)
Inventor: TOMOSY THOMAS E
IPC: B63H16/08
Filed: 1999-07-09
Abstract: The finboard is a muscle powered personal water craft, comprising an elongated buoyant body (the board) and two horizontal fins attached to said body by elastically restrained hinges. When the board is in use, the user stands on its deck, balancing and controlling it by the help of a vertical shaft, securely attached to said deck terminating in a horizontal handle bar.      Forward motion is achieved by the user lowering and raising his center of gravity by flexing his knees repeatedly. The board, in reaction to the periodic downward momentum, reacts by alternately sinking deeper into the water then rising higher again. The fins, due to the resulting hydrodynamic pressure against their surfaces, respond to this vertical oscillation by adapting a periodically changing slanted attitude which converts each vertical displacement of the board to a horizontal forward driving momentum.        The fact that the fins offer a continuous drive (as opposed to the intermittent drive of paddling) combined with the fact that oscillating fin drives are known to be more efficient than either paddles or propellers, endow this invention with the potential of becoming the fastest muscle-powered water craft.
