  • Patent number: 5455874
    Abstract: Continuous tone images, represented by original data files are compressed by (1) transforming by a lapped orthogonal transform the original file of data to generate a transform file of coefficients, (2) quantizing the transform coefficients, and (3) coding the quantized values to generate a compressed data file, the lapped orthogonal transform being arranged to compute all transform coefficients by means only of bit shifts, negations, and adds. In another aspect, the quantization and coding are performed on groups of transformed coefficients.

  • Patent number: 4974224
    Abstract: Routing variables for near optimally controlling the distributed flow of information signals from a node s over a multinode communication network to a destination node d are generated in accordance with a prescribed heuristic among network path delays. A prescribed routing variable value (e.g. zero) is assigned to each route to a node n, representing that that node is not to be used to route information signals from node s to node d, for any node of the network that either is not directly connected to node s, has not established a connection path to a destination node d, or is using node s as part of its communication path to destination node d. The path delays from node s to neighboring nodes n are measured and a measurment of the path delay from node s to destination node d is obtained. In addition periodically updated measurements of the path delays from neighboring nodes n to destination node d are received.
