Abstract: Apparatus and methods for compressing data points. The invention compresses the representation of a sequence of points in a space by, for example, dividing the sequence of points into segments of successive points and then compressing each of the segments irrespective of the compression applied to the other segments. The dividing may include dividing the points sequence into segments of S successive points. The value of S may be the value of S generating the smallest of the multiple compressions. The compression may include compressing each of the segments of S successive, i-bit points into segments of j-bit points, where j<=i,j may vary from segment to segment and, for any given segment, j is the minimum number of bits necessary to represent the data in that given segment.

Abstract: Inadvertent disconnection between a receptacle and a modular connector is achieved by fitting the connector with a new type of protective sleeve. The sleeve interior defines a first cavity sized to accept the connector and further defines a smaller cavity sized to admit the projecting connector tail. With the connector mated to the receptacle, the sleeve is slid forward. The exposed portion of the connector fits within the first sleeve cavity, and the connector tail fits within and is captured by the smaller cavity. The smaller cavity defines a connector tail capture region that constrains movement of the connector tail. More particularly, the capture region prevents unintended movement of the connector tail in a direction that would release the connector from the receptacle. This arrest feature prevents interruption of the connector-receptacle mechanical and electrical connection.
