Patent EP-0469247-A2 (EP)
Inventor: WIEDMANN SIEGFRIED KURT
IPC: G11C11/414
Filed: 1991-05-03
Abstract: This invention relates generally to the accessing of random access access memory arrays and, more specifically to circuits and techniques for increasing the data valid time of such memory arrays without increasing either the access or cycle times of the array. This is accomplished by providing, during a read cycle, a read signal directly to an output driver (32) and simultaneously providing, via a parallel path, a latch output to the same driver (32). The latch output is provided under control of the read signal and a returning portion of a clock pulse such that the latch output overlaps the direct read signal from a sense/read amplifier (31). An output is provided from the latch (33) until it is reset and may last well into the next read cycle even when a new read signal is present. The technique utilized, in addition to providing a longer data valid time, eliminates a response of the latch (33) to spurious read signals because a latch output is not provided until the clock is deactivated and such spurious read signals are not present during the returning portion of the clock cycle. The approach utilized also has the advantage that delays associated with prior art serially disposed latches (33) are eliminated.

Abstract: A direct optical connector (DOC) comprised of first (201) and second members, each including a plurality of light emitting (202, 204) and light detecting (205, 203) locations, operative in combination with energy transfer media (210) to form direct optical connections between the light emitting locations (202, 204) and the light detecting (203, 205) locations, wherein said first (201) and second members are adapted for reclosable connection to each other whereupon the light emitting locations (202) on one member are aligned with the light detecting locations (205) on the other member. The first (201) and second members of the preferred DOC are modular. Alternative forms of energy transfer media (210) are used in various embodiments of the invention including lenslet arrays, imaging fiber plates (IFPs), and energy transfer fiber plates (ETFPs). These media have differing alignment criteria, differing degrees of immunity from crosstalk, differing degrees of transfer efficiency, different manufacturing costs, etc., thereby permitting the fabrication and/or use of a connector most suited to meet the requirements of a particular application. A modular half of a DOC can be used in conjunction with a remote optical connector (ROC) to channel light over relatively long distances. The invention also encompasses processes for fabricating ROCs.

Abstract: Disturbances to DTMF signaling between mobile stations and the land-based system caused by handoff are minimized. DTMF signals are transmitted in real time between a mobile station and its associated base station. However, if during a DTMF transmission between a base station and the mobile switching center a handoff is requested, the handoff is delayed by a specified time in order to allow completion of the DTMF transmission. Alternatively, both base stations involved in the handoff transmit overlapping DTMF tones until the handoff is completed. If the handoff is requested before the start of the DTMF tone transmission, the DTMF transmission is delayed until the handoff is completed.

Abstract: This shift amount detector determines the shift amount to normalize binary bit data. It is provided with means (10) to add, to an n bit data to be normalized, at least one bit of logical value "0" on the side of the least significant bit. The data with additional logical value "0" has its bits reversed by the bit reversing circuit (12) when the data is negative or positive. The data with the additional logical value "0" is input to the bit detecting circuit (14) as it is or as data with reversed bits according to the selection by the selecting circuit (13). The bit detecting circuit (14) detects the bit position where "1" or "0" appears for the first time by searching the bits one by one starting from the most significant bit and outputs the result of detection to the shift amount calculating circuit (15). The shift amount calculating circuit (15) determines the shift amount based on the detected bit position.

Abstract: A heterojunction bipolar transistor having a single-crystal emitter with reduced charge storage and acceptable current gain is described herein. The heterojunction transistor comprises a collector region (604), a base region (606) formed on the collector region, and a single-crystal emitter region (608) grown on the base region (606) by low temperature epitaxy. During the formation of the base region (606), a graded profile of 5-23% germanium is added to the base, as the distance to the collector region (604) decreases, thereby decreasing the base bandgap as it approaches the collector region. Further, during the formation of the emitter region (608), a graded profile of 0-20% germanium is added to the emitter as the distance from the emitter-base junction increases. Thus, the emitter bandgap decreases as it moves farther from the emitter-base junction. The result of the above grading profiles is that the emitter bandgap is narrower at the emitter contact than the base bandgap at the emitter-base junction.
