US6526531 | https://patentimages.storage.googleapis.com/fb/6f/fd/7ffd6da1e593b6/US6526531.pdf | Title: Threshold detection for early termination of iterative decoding.Claims: What is claimed is: 1. In a signal processing application a method of decoding an encoded frame comprising the steps of:a) decoding during a current iteration of iterative decoding the encoded frame to provide a decoded frame including decod... | An iterative decoder decodes a frame of encoded data that includes error detection information and terminates the iterative decoding based on a comparison of the decoded frame with the error detection information. The iterative decoder may have a maximum number of specified iterations but may terminate the number of it... |

US6356213 | https://patentimages.storage.googleapis.com/19/ff/6e/c92329c7a320ec/US6356213.pdf | Title:System and method for prediction-based lossless encoding.Claims: What is claimed is: 1. A method for signal coding comprising the steps of:a) identifying a segment of a signal for coding;b) determining a first predicted value for a given sample within said identified signal segment as a function of prior sample v... | A lossless encoding methodology is described based on residual coding techniques and using a modified Least Mean Squares methodology to develop a predictor for a signal to be encoded and a residual as the difference between the signal and its predicted value. After the residual for an input signal segment is obtained a... |

A data communications method comprising:dividing the input stream of data into a plurality of packets;identifying a respective packet history state for particular ones of the packets as a function of at least one acknowledgement ve... | A method and apparatus for compressing packets that enables inter-packet compression thereby achieving greater robustness and increased compression ratios without the deleterious effects e.g. the effect of packet loss multiplying of prior compression schemes. More particularly a so-called acknowledgment scheme is emplo... |

Claims: What is claimed is: 1. A portable map display system comprising:a) a portable map display device comprising:i) a display unit;ii) a self-locator unit for detecting a location of the portable map display device;iii) a direction ... | A system and method for displaying map data to a person using either a hand-held or head-worn display is described. In one preferred system a head-worn display is used. The location of the person and the direction of the persons view is determined. A map image indicated by the location and direction is presented in the... |
