|
 |
An invention to losslessly compress two dimensional data. A simple
heuristic algorithm compresses chip data by 20:1 or more.

100Base-T2 Signaling |
|
 |
While at SMC I proposed a scheme for transmitting 100Mb Ethernet over Category 3 twisted pair cable. This scheme transmitted data with a 3 level code on 3 wire pairs while listening for a collision on a forth pair. This arrangement eventually became the ill-fated 100BaseT2 standard. |
100BaseT Multi-Standard Auto-negotiation |
|
 |
This patent allowed for different 100Mb Ethernet to co-exist in a signal adapter. |
PCB Current Shunt |

|
Developed this for low cost consumer mains power measurement. Uses a PCB track for a current shunt and compensates for heating effects with a simple DSP algorithm. |
