Title: Method and apparatus for detecting a transmitted control code for initiating a latching loopback test procedure
Inventor: FAIN MARC
IPC: H04M3/24
Filed: 1991-02-20
Granted: 1994-08-02
Abstract: In a data port for a digital data system in which latching loopback is implemented, a unique and efficient algorithm is utilized to achieve M out of N control byte recognition.  In the algorithm, N-M+1 variable length windows are used to count identified control bytes.  The algorithm opens a window when the desired byte has been detected, counts the identified bytes while the window is open, and closes the window when a non-target byte is detected.  The counts in the various windows are summed to determine if M bytes have been detected.  A window having the oldest byte count is effectively dropped so that the window is available to count newly-arriving target bytes.

Abstract: A method of adaptively multiplexing a plurality of video channel data is disclosed.  A multiplexed data includes a plurality of frames each of which contains a plurality of sub-frames.  The video channel data are adaptively allocated to the sub-frames.  A memory occupancy value of a buffer, which is provided in each of a plurality of video channels, is determined.  The buffer is arranged to receive the corresponding video information.  A plurality of control signals are produced each of which indicates the memory occupancy value of the corresponding buffer.  Following this,  a look-up table is accessed which includes a plurality of video channel assignment data for assigning the video channel data to the sub-frames.  Thus, one of the channel data assignment data is derived from the look-up table.  The video channel data are then multiplexed using one of said channel data assignment data derived from the look-up table.

Title: Drag embedment marine anchor
Inventor: BRUCE PETER
IPC: B63B21/26
Filed: 1992-11-27
Granted: 2006-02-07
Abstract: A marine anchor (1) comprising a fluke (8) and a shank (3) attached to the fluke (8) is intended for drag embedment in a mooring bed (63) by pulling the anchor (1) substantially horizontally via the shank (3). Further, it is a particular feature of the anchor that two modes of operation are possible by means of the line (56) extending between the anchor cable attachement point (4A, 4B) an the shank and the fluke centroid (7) being variable to provide a first line (5) present for drag embedment of the anchor (1), and a second line (6) utilised when the anchor is embedded, wherein the pulling force on the anchor via the shank (3) can now be essentially upwards thereby providing an increased holding force due to the increased fluke area presented in the direction of the upwards force. The change in direction from the first line (5) to the second line (6) can be achieved by having the shank (3) pivotal (Fig. 9) and by providing pivot control means (26, 29) permitting selective pivoting of the shank (3).      Alternatively two separate cable attachment points (4A, 4B) can be present in the shank (3) with, as a first example (Fig.      I)two separate cables attached to said points (4A, 4B) whereby the two modes of anchor operation are achieved by transferring operation from a first cable to the second, or as a second example (Fig. 6) moving the single anchor cable (64) via a guide (11) from the first attachment point (4A) to the second (4B).
