| Number | Title | Issue Date |
| 5558536 | Circuit connector block A 110-volt wiring connector wherein sets of wire connectors are positioned on each of four sides, each set of the sets of 1-4 having three in-line electrodes as connectors, corner electrodes are interconnected, and the center electrodes are bridged as bet... | 09/24/1996 |
| 5363108 | Time domain radio transmission system A time domain communications system wherein a broadband of time-spaced signals, essentially monocycle-like signals, are derived from applying stepped-in-amplitude signals to a broadband antenna, in this case, a reverse bicone antenna. When received, the t... | 11/08/1994 |
| 4979186 | Time domain radio transmission system A time domain communications system wherein time modulated, impulse derived signals are multiplied by a template signal, integrated, and then demodulated. By this process, usable signals are obtained which would be otherwise obscured by noise.... | 12/18/1990 |
| 4813057 | Time domain radio transmission system A time domain communications system wherein time modulated, impulse derived signals are multiplied by a template signal, integrated, and then demodulated. By this process, usable signals are obtained which would be otherwise obscured by noise.... | 03/14/1989 |
| 4743906 | Time domain radio transmission system A communications system wherein there is employed a signal mixer in which a received signal is multiplied by a template signal, and then the output of the mixer is integrated. By this process, usable signals are obtained which would be otherwise obscured ... | 05/10/1988 |
| 4641317 | Spread spectrum radio transmission system A communications system wherein an intelligence signal modulates the spacing of relatively narrow pulses of a fixed rate pulse train, and these pulses key on a transmitter which employs a pair of series connected avalanche mode operated transistors. These... | 02/03/1987 |
