Title: Apparatus and methods employing distribution preserving tomlinson precoding in transmission of digital data signals
Inventor: COLE PAUL DANA
IPC: H04L25/49
Filed: 1992-02-06
Abstract: A transmitter (10) is provided with a distribution preserving Tomlinson coder (25) which predistorts shaped data signals (20) such that the power of each data signal exiting the coder is substantially similar to the power of the data signal entering the coder and such that upon transmission of the predistorted data signal over a channel (40), the effect of ISI of the channel is substantially removed.

Different methods for so choosing s k are disclosed. Receivers (50) which cooperate with the provided transmitters (10) are also provided.

Title: Packet Switching System for Forwarding Packets from Input Buffers Using Idle/Busy Status of Output Buffers
Inventor: FAN RUIXUE
IPC: H04L47/6275
Filed: 1993-12-29
Abstract: A packet switching system comprises input buffers and output buffers, and a self-routing network for routing packets from the input buffers to the output buffers according to the routing information contained in their header. An input controller, associated with each input buffer, includes an idle/busy memory. An output controller, associated with each output buffer, detects the idle space of the associated output buffer and determines if the idle space is greater than a predetermined value. If the idle space is determined to be greater than the predetermined value, an idle status bit is generated and if the idle space is determined to be smaller than the predetermined value, a busy status bit is generated. The idle and busy status bits are broadcast to the idle/busy memory of all input controllers. Each input controller writes an incoming packet into the associated input buffer and reads it onto the self-routing network if an idle status bit is stored in the idle/busy memory corresponding to the routing information of the incoming packet.

Title: Internal line up clamp
Inventor: LEDUC TRUNG
IPC: B23K37/053
Filed: 1994-05-31
Abstract: INTERNAL LINE UP CLAMP     ABSTRACT    An improved internal line up clamp (10) is disclosed which has an integral back up ring (12).  A first set of pipe clamps (22) move radially outward to engage the inner surface of a first pipe (14).  A second set of pipe clamps (62) and a set of back up ring segments (202) are simultaneously moved radially outward into engagement with the inner surface of the pipes.  The back up ring segments (202) are spring loaded to exert a relatively constant back up force against the inner surface of the pipes at the weld.  In a modification, a fill block (118) can be used to fill the gap between adjacent back up ring segments when engaging the inner surface of the pipe.  The back up ring segments support the shoe elements (220).          The shoe elements are spring loaded to accommodate diameter mismatch and non-circularity of the pipe ends.          The back up ring segments rotate about a radial axis from the pipe centerline.  Tapered ends on the back up ring segments provide for the decrease in ring circumference necessary to lower the ring segments.

Title: Synchronization Adder Circuit
Inventor: HIRAMATSU KATSUHIKO
IPC: H04L5/06
Filed: 1994-09-09
Abstract: A synchronization adder circuit for digital data communication is provided. This circuit includes an A/D converter, a waveform-shaping circuit, a square circuit, a low-pass filter, and an adder. The A/D converter samples at given sampling points in time per sampling cycle a received signal transmitted through a plurality of subcarriers to digitize sampled values to provide digital signals. The waveform-shaping circuit then waveform-shapes the digital signals from said A/D converter without decomposing them with respect to each subcarrier. The square circuit squares the output signals from the waveform-shaping circuit. The low-pass filter removes a given high-frequency component from output signals from the square circuit. The adder adds values of output signals from the low-pass filter at each sampling point for preselected sampling cycles to determine the samples suitable for reproduction of original data.
