Latest Patents
One of his latest patents is titled "Data transmitter and method therefor." This invention provides a data transmitter that performs digital to analog conversion, convolution with an arbitrary finite impulse response, and smoothing of the output functions without requiring a separate anti-aliasing low pass filter. The implementation involves convolving a digital input data value with a desired impulse response, allowing for the creation of a smooth signal output that does not require further filtering.
Another significant patent is "Method and apparatus for reconstructing LAN frames following transfer." This invention addresses the segmentation of variable length LAN frames into fixed length cells, enabling the transportation of data through an intermediate cell-based system, such as an ATM network. The method allows for the insertion of special symbol combinations into time gaps between data units, facilitating the forwarding of frame-representing data as a 'stretched frame' without waiting for all cells to arrive.
