| Number | Title | Issue Date |
| 5383184 | Multi-speaker conferencing over narrowband channels A system for digital conferencing over narrowband channels which allows use by multiple simultaneous speakers and which allow for interfacing between vocoders which operate at different bit rates. The system takes advantage of the properties of multi-rate... | 01/17/1995 |
| 5365425 | Method and system for measuring management effectiveness A system and process are presented in which the factors of quality, cost, and access are integrated in such a manner as to provide a holistic description of the effectiveness of care at medical treatment facilities (MTFs). By using medical treatment data ... | 11/15/1994 |
| 5324997 | Delayed negative feedback circuit A modification to the design of high speed logic circuitry will increase the speed of the circuitry. The modification consists of a delayed negative feedback added to the interface between two gates (a driving gate and a driven gate). The feedback is dela... | 06/28/1994 |
| 5317567 | Multi-speaker conferencing over narrowband channels A system for digital conferencing over narrowband channels which allows use by multiple simultaneous speakers and which allow for interfacing between vocoders which operate at different bit rates. The system takes advantage of the properties of multi-rate... | 05/31/1994 |
| 5315603 | Backscatter absorption for laser diodes Whenever any laser is interfaced with any type of optics there is always backscatter back into the laser. For diode lasers this backscatter makes it emit chaotic radiation where the frequency spectrum is broad and contains many different frequencies. This... | 05/24/1994 |
| 5315513 | System for modelling moderate resolution atmospheric propagation MODTRAN is a moderate resolution model and computer code used to predict atmospheric transmittance and background radiance in the microwave, infrared, visible and near ultraviolet spectral regions (0 to 50,000 cm-1 or 0.2 m to infinity). The co... | 05/24/1994 |
| 5301208 | Transformer bus coupler A transformer bus coupler, which connects a transceiver to a data bus without impedance discontinuities. The transformer bus coupler maintains the voltage-to-current ratio of signals as they enter and leave the coupler by providing a shunt circuit that at... | 04/05/1994 |
| 5293046 | Optical high pressure sensor A high pressure sensor which uses a ruby as a pressure sensor is disclosed. This system includes a high pressure Hg lamp which is used to excite the ruby R1 and R2 lines because it has a spectrum which is a good match to the ruby absorption spectrum. The ... | 03/08/1994 |
| 5276839 | System for programming EEPROM with data loaded in ROM by sending switch signal to isolate EEPROM from host system An EEPROM programming circuit is disclosed which provides for the on-board rogramming of a EEPROM memory using: a microprocessor, a bootstrap ROM, a UART communications port, and a Eccles-Jordan flip flop switch system. These elements are electrically conn... | 01/04/1994 |
| 5272698 | Multi-speaker conferencing over narrowband channels A system for digital conferencing over narrowband channels which allows use bymultiple simultaneous speakers and which allow for interfacing between vocoders which operate at different bit rates. The system takes advantage of the properties of multi-rate ... | 12/21/1993 |
