Title: Router device and data communication system
Inventor: SAITO SHUICHI
IPC: H04L12/46
Filed: 1993-03-22
Granted: 1999-07-13
Abstract: In a router device of the present invention, the routing controller refers to the routing address table to determine whether the received frame is to be routed (whether the frame passes through two or more router devices, for example).  The multiplication controller multiplies the frame selected as the subject of routing and has the path controller set paths between router devices for transmission of the multiplied frames.  The frame for which a path is set is transmitted with the destination address of the router device as the other party of communication.  When a multiplied frame is received, the multiplication controller extracts an ordinary frame from the multiplied frame and sends it to the device indicated by the original destination address.

Title: Fiberglass cloth resin tape insulation
Inventor: WEINBERG MARTIN J
IPC: H01B17/56
Filed: 1993-05-03
Granted: 1997-09-16
Abstract: An improved electrical insulation tape is formed from a sheet of fiberglass cloth having a layer of thermoplastic resin bonded thereto. The thermoplastic resin layer is applied to the fiberglass sheet by melting the resin while contacting the fiberglass, and then the composite is cooled to bond the two components together. The composite sheet is then slit into tapes with substantially no unraveling of the fiberglass component at the slit edges of the tapes. The resultant tapes are easily wrapped on, and adhered to, conductors, such as magnet wire, or the like, by remelting and resolidifying thethermoplastic layer. The tape possesses excellent dielectric properties and heatdissipation properties. Alternatively, the fiberglass sheet may be impregnated with the melted thermoplastic component whereby a composite, rather than a relatively definitive two layer laminate, is formed.

Title: Discontinuous cdma reception
Inventor: DENT PAUL W
IPC: H04W56/00
Filed: 1993-04-08
Granted: 2001-10-02
Abstract: A cellular radio telephone system employs discontinuous transmission and reception of speech signals to conserve receiver processing resources. A frame structure is imposed on digitized speech data to divide the data into units of fixed transmission time. When no active speech is present for the entire duration of a frame, transmission of that frame of data is inhibited. At the receiver, decoding of received bits is performed to determine correlation with a defined set of code words. If no correlation is found after the first few received bits of frame, due to the absence of active speech data, decoding is discontinued for the remainder of the frame's duration. This approach frees up the receiver's resources for other tasks, such as decoding of other received signals. Frames of data from different sources are transmitted with a defined time alignment to enable the receiver to remain synchronized in the absence of transmitted data. The frames associated with different sources are staggered relative to one another, to distribute processing loads at the receiver.
