Did You Know...
...that Thomas Edison's patent application on his phonograph was approved by the Patent Office in just seven weeks? In contrast, it took Gordon Gould, the inventor of the laser, 30 years to obtain his patent -- finally awarded in 1988!

| Number | Title | Issue Date |
| 6061711 | Efficient context saving and restoring in a multi-tasking computing system environment In a multi-tasking computing system environment, one program is halted and context switched out so that a processor may context switch in a subsequent program for execution. Processor state information exists which reflects the state of the program being ... | 05/09/2000 |
| 6037810 | Electronic system having a multistage low noise output buffer system In one embodiment, a multistage output buffer supplies current to a load by successively turning ON output buffer circuits which transition from an OFF state to approximately a saturated state during approximately mutually exclusive periods of time. Thus,... | 03/14/2000 |
| 6009391 | Line spectral frequencies and energy features in a robust signal recognition system One embodiment of a speech recognition system is organized with speech input signal preprocessing and feature extraction followed by a fuzzy matrix quantizer (FMQ). Frames of the speech input signal are represented in a matrix by a vectorf of line spectra... | 12/28/1999 |
| 5926544 | Direct current feed with line status change adaptation in a communication system A line card integrates subscriber line interface circuitry, A/D and D/A converters, and digital signal processing technology. The digital signal processing technology performs many line card tasks such as switch hook detection, ground key detection, DC fe... | 07/20/1999 |
| 5821886 | Variable length code detection in a signal processing system A group of incoming data stream bits having packed variable length code ("VLC") words is applied to an entropy code bit length searching module. The group of bits is replicated within a plurality of matching modules selectively distributed among entropy c... | 10/13/1998 |
| 5798953 | Apparatus and method for determining a number of digits leading a particular digit When a data input signal having R plus X groups of M digits is received, the digits are segmented such that X different first counter-detectors receive M digits and a second counter-detector receives the R digits. The counter-detectors determine a number ... | 08/25/1998 |
| 5781134 | System for variable length code data stream position arrangement An entropy code look up table processes incoming data and provides an n-bit output signal having an entropy code word and a bit-- length output signal. Entropy code words are successively packed without spacing bits into two sixteen-bit latches... | 07/14/1998 |
