| Number | Title | Issue Date |
| 4964063 | System and method for frame and unit-like symbolic access to knowledge represented by conceptual structures Conceptual structures which can be used to represent any knowledge that can be represented by frames/units. Its realization, in a software program called Unit Interface, provides a method of storing frame/unit data in conceptual structures and algorithms ... | 10/16/1990 |
| 4953068 | Full bridge power converter with multiple zero voltage resonant transition switching A full bridge switching power converter employs zero-voltage, resonant-transition (ZVRT) switching techniques which appreciably reduces the switching losses at high switching frequencies, (for example, 1 MHz and above), using constant frequency, pulse-wid... | 08/28/1990 |
| 4943969 | Isolation for failures of input signals supplied to dual modules which are checked by comparison Failures of duplicate input signals to two indentical electronic modules which may be units, cards, circuits or other entity, are detected by comparison. In each electronic module functional input signals are captured in a plurality of latches on differen... | 07/24/1990 |
| 4933908 | Fault detection in memory refreshing system A dynamic random access memory (DRAM) memory refreshing scheme utilizes at least two separate refresh channels. Each of the channels consists of a pair of identical counters which are coupled through two different types of timing chains. One of the timing... | 06/12/1990 |
| 4930106 | Dual cache RAM for rapid invalidation A cache buffer for a multiprocessor system utilizes two RAMs to store validity bits. Use of these RAMs greatly reduces chip area required to implement the validity buffer and reduces interconnection foil (printed connectors) and hence propagation time. An... | 05/29/1990 |
| 4929050 | Traveling wave fiber optic interferometric sensor and method of polarization poling fiber optic An optical light conducting fiber that has a D-shaped stress sensitive coating of PVF2 which covers substantially equal length segments of said fiber, so that each of said segments is separated by equal uncoated segments of substantially the sa... | 05/29/1990 |
| 4926426 | Error correction check during write cycles An error correcting check of a memory system is provided when a memory in which the Dynamic Random Access Memory (DRAM) is of the type which has input lines that are directly coupled to its output lines. Utilizing this type of DRAM, the memory system empl... | 05/15/1990 |
| 4918696 | Bank initiate error detection A multibank computer memory system is provided in which the storage banks monitor the initiate line while each bank operation is being processed to verify that another initiate is not received before it can be processed. This serves to check that the cont... | 04/17/1990 |
| 4918695 | Failure detection for partial write operations for memories A failure detection system for variable field partial write system for merging data bits in a memory word upon programmable request is described. The variable bit field can be selected for any number of bit positions from a single bit up to and including ... | 04/17/1990 |
| 4912476 | Antenna interface common module An improved interface arrangement between an antenna controller and one or more antennas. The interface includes a reduced number of control lines but is capable of handling complete interface requirements including control and status between the antenna ... | 03/27/1990 |
| 4908542 | Saw tapered transducers A Surface Wave Acoustic (SAW) is constructed with hyperbolically curved electrode fingers. The transducers consist of relatively narrower inner electrode fingers and relatively wider outer electrode fingers, and may also be divided into a plurality of tra... | 03/13/1990 |
| 4899311 | Clamping sense amplifier for bipolar ram A sense amplifier is provided for a bipolar random access memory that has memory cells arranged in a column and a pair of bit lines for said column of memory cells. A first bipolar transistor has its collector-emitter path coupled to one of the bit lines ... | 02/06/1990 |
| 4885675 | Transformer isolated AC to DC power conditioner with resistive input current A single stage power conditioner which produces an isolated DC output while drawing resistive input current from the utility has been described. A high frequency switch-mode technique was used which operates in continuous conduction mode to reduce electro... | 12/05/1989 |
| 4875180 | Multi-function scaler for normalization of numbers A left justification scale factor generator is described which is capable of scaling numbers for binary number groups off one, two, three and four bit groups. Two basic building block circuits are utilized in the scale factor generator's priority encoder,... | 10/17/1989 |
