Title: Synchronization of television vertical deflection system
Inventor: WAEHNER GLENN CARL
IPC: H04N3/16
Filed: 1990-09-24
Granted: 1998-06-30
Abstract: Vertical deflection circuitry for substantially eliminating rolling and bouncing in a video monitor, where for example, the video monitor (260) successively displays images produced by each of one of a plurality on non-synchronized video cameras (161, 162) and an incoming vertical synchronization (synch) signal (230) to the monitor is merely a composite of the individual vertical synch signals (210, 220) generated by each of these cameras. Specifically, the vertical deflection circuitry (300) generates the appropriate vertical sweep signal for a current one of these cameras from this composite synch signal so as to properly locate the corresponding video image generated by this camera on a display screen of the monitor. Inasmuch as the vertical deflection circuitry is re-triggerable (310), then, whenever an out-of-lock condition occurs between a camera and a monitor, this circuitry can establish a vertical lock condition on the next incoming vertical synch pulse in the composite synch signal rather than requiring numerous vertical frames to occur before vertical synchronization is achieved between that camera and monitor.

Abstract: A computer-based file system enables user access to any of a plurality of previously-stored data files, each file being identified by at least two file names formatted using different file name formats. The system receives a user request including a purported file name having one or more appended segments and a base name, at least one of said appended segments being used to identify the file name format of said base name. The system then checks file names which utilize the identified file name format to locate a data file of the previously-stored data files having a file name which is the same as said base name. According to another feature, data files are identified using one file name format from which the system compiles a file name using the file name format identified in the appended segment. The base name is then compared against the computed file names to locate the desired base name file. (FIG. 1)

Granted: 1998-09-15
Abstract: High speed telecommunication systems are disclosed which use a novel line coding scheme for better performance. The line code according to the scheme can be used to produce a block code of arbitrary length. It bounds the minimum number of transition in a block, and the dc balance of the code. The overhead required is 2 bits if framing is not included and 3 bits if it is. A lookup table is not required to implement the code, thus it remains efficient for longer block lengths. The algorithm required to encode and decode the data can be implemented in serial at the transmission rate or in parallel at the block rate. The coding scheme results in a significant reduction in hardware components of the communication system.
