Inventor: NO JONG-SEON
IPC: H03M13/23
Filed: 1990-10-15
Abstract: Synchronization conditions of a Viterbi decoder are detected using the differences between minimum branch metrics and corresponding minimum path metrics. In accordance with the invention, zero differences are monitored, non-zero differences are monitored and weighted, and the monitoring is used to detect in-synchronization or out-of-synchronization condition of the decoder. More particularly, the differences are non-linearly mapped (F3) into a value in a first set for some differences or a value in a second set for the other differences. The sign of a value in the first set is different from all of the signs of the values in the second set. In one embodiment, the first set includes a single value of unity, whereas the second set includes a value corresponding to the difference. In accordance with the method of synchronization detection, an accumulator, counter or indicator is initialized (F1) to an initial value and as the mapped values are produced in sequence, they are sequentially summed (F5) with the value of the accumulator, counter or indicator so as to continually update the sum. The value of the accumulator, counter or indicator is compared to an out-of-synchronization threshold and to an in-­synchronizatioh threshold (F6, F7). Each time the value of the counter, accumulator or indicator reaches or exceeds the value of the out-of-synchronization threshold, an out-of-­synchronization status is declared (F9) and the counter, accumulator or indicator is returned to its initialized value, and the process continues. On the other hand, if the value of the accumulator, counter or indicator drops below the in-synchronization threshold, then an in-­  synchronization status is declared (F8) and the value of the counter, accumulator or indicator is clamped so that it cannot drop any further below the in-synchronization threshold.

Abstract: A direct current traveling wave motor generates motive force by utilizing shear deformation resulting from electrical contact between a rolling element and a layer of material that experiences shear deformation in response to an applied electric field. In a rotary piezoelectric embodiment, rotation of a motor shaft results from the non-uniform electric field intensity around the contacts between rollers surrounding the shaft and an outer race of piezoelectric material that undergoes shear deformation. Rotation occurs as the rollers roll down the faces of piezoelectric shear waves that travel with the rollers. The rollers perform the function of commutators, but without sliding friction, and they eliminate the need for traditional roller bearings. Zero clearance between motor parts results in shaft stiffness that allows precise positioning and high speed operation. The piezoelectric motor has high efficiency because sliding friction is eliminated, eddy currents are not generated, and most of the internally flowing current is local and reactive. Efficiency of the motor exceeds 98%, and its silent, smooth operation is capable of very high speeds. Speed of the motor is controlled by varying the DC potential. The motor may be operated by a battery, it does not require lubrication, and it will operate while flooded with slightly conducting fluids, such as salt water. The scale of the motor can range from miniature for driving a watch to very large for driving an oceangoing ship.

Abstract: A valve assembly for supplying air under pressure to the firing chamber of an air gun includes a hollow cylindrical chamber (2) which houses a slidable piston (3) whose external diameter is slightly less than the internal diameter of the cylindrical chamber to define an airflow passage therebetween. Air under pressure is admitted to that portion of the chamber interior which lies to one side of the piston and the piston is moved along the chamber immediately before release of the air from the chamber in a sense further to compress the air present therein. The re-compressed air can then be selectively released from the cylindrical chamber to the firing chamber of the air gun.

Abstract: Modulation-induced thermal crosstalk between the independently addressable lasers (12) of a monolithic multilaser array (10) is reduced by forming each laser with two optically coupled active regions, an amplifier region (16) and a modulator region (18); biasing the amplifier region in such a way that stimulated emission is caused to occur therein, and varying the electrical condition of the modulator region in order to modulate the lasers. Modulation of the laser output is achieved by varying the internal optical loss of the modulator region, known as Q-switching. In one form, control of this loss is achieved by varying the reverse bias voltage applied to the modulator region. In another form, control of this loss is achieved by selectively connecting and disconnecting regions of p-type and n-type material in the modulator region together. In a third form, control of this loss is achieved by selectively connecting and disconnecting the modulator region to ground potential. Q-switched operation of laser results in a cooling of the laser during operation, thereby reducing the transient heat generated during modulation, and thus reducing thermal crosstalk between lasers.

Abstract: A multi-bolt lock, especially for doors, comprises a latch (2, 2') in a lock case (1) and at least one displaceable push rod (11, 12) having at least one bolt. The push rod (11, 12) is displaced via a press-button, for example by rotating the latter upwards, with a gear or lever system being interposed. The latch (2, 2') has a blocking part (14, 14') which is located inside the lock case (1) and which, with the latch pushed forwards completely (that is to say, also with the door open), engages with a blocking effect into the gear or the lever system or directly into the push rod, so that the multi-bolt lock cannot be actuated. With the latch (2, 2') pushed back at least partially, the blocking part (14, 14') disengages and allows the push rod (11, 12) to be actuated. In order to push the latch (2, 2') in somewhat, a stop, especially a spring-loaded flap (19, 19'), is provided in the closing piece (16, 16') located on the jamb.
