Abstract: Binary data (i.e. user data byte fields and corresponding ECC data byte fields) that is to be recorded as multi-byte data records on magnetic recording media, such as a disk, is randomized prior to being run-length encoded and written to disk. Subsequently at read back, the records are first decoded, and then derandomized in a complementary fashion. The scheme generally writing data byte patterns that tend to stress the ability of the head/disk interface to record the magnetic data transitions at the proper linear track positions on the disk as well as tending to avoid presenting a repeating pattern of read-errors to the read channel's ECC network. Thus, read-errors are not propagated through the read channel. Binary data is randomized, and the randomized data is subsequently derandomized, in a repeating or pseudo random, complementary sequence for each byte of each data record determined by the binary count that is contained in a counter, initialised at the beginning of a data record, and is progressively incremented to the predetermined next count as each byte of the multi-byte data record is progressively processed. E.g., the first four bits of each byte are multiplied by the first four bits of the 8-bit counter, and the last four bits of the byte by the last four bits of the counter. Subsequently, during derandomizing, division by way of a multiplication-of-the-inverse technique is used, the first four bits of each byte inverse order of the last four bits of the counter, and the last four bits of the byte by the the inverse order of the first four bits of the counter.

Abstract: A hand held hammer machine comprises a housing (10) with a cylinder (11) therein, in which a reciprocating drive piston (40) via a gas cushion in a working chamber (44) re­peatedly drives a hammer piston (15) to impact on the neck (17) of a tool (20) carried by the machine housing (10) as soon as a feeding force is applied via the machine housing (10) to the tool (20) and an interposed recoil spring (23) pre-stressed between fixed shoulders (28,22) in the housing (10) starts being compressed in response to tool penetration into the housing (10). Therein and within the spring (23) and around the path of movement of a piston rod (13) of the ham­mer piston (15) is affixed one end (26) of a sleeve (25), which by its other end forms a stop (30) limiting the pene­tration of the tool neck (17) into the machine housing (10) to a maximally allowable extent. The range of movement of the neck (17) wherein it can receive repetitive impacts lies be­tween beginning and maximal compression of the spring (23) counted from its precompressed state which defines an idle position for the neck (17), and in that idle position and within that range proper uncovering of porting (45) in the cylinder wall is assured with the hammer piston seal (16) out of hazardous alignment with said porting (45) at the impact­ing instants.

Abstract: A compact character string retrieving system (1) capable of producing correctly the result of matching (205) without omission even upon occurrence of multiple matching (306) in which a plurality of search terms are matched for one character string (at 280) by a finite automaton. A destination state for transition brought about by a trailing character of the search term is newly created instead of an initial state. A transition table storage (220) stores the destination state. On the basis of the source state number and a specified pattern character code, the destination state number is read out from the state transition table storage (220). When the state number read out represents the destination state of the transition brought about by the trailing character of the specified pattern character string, an identifier thereof is outputted. The identifiers of the search terms matched are each represented by one bit information, and a group of corresponding flags is stored in one slot. Multiple matching (280) can be performed without omission. The character string retrieving system is implemented in a reduced size.

Abstract: A pacemaker mediated tachycardia (PMT) is detected by circuitry (166, 170, 174, 176, 178, 180, 182, 184, within an implantable pacemaker (160). The PMT is detected by first detecting a tachycardia condition that includes a prescribed number of consecutive cardiac cycles having a rate faster than a prescribed rate. Each cardiac cycle of the tachycardia condition includes a natural atrial event, i.e., a P-wave, and a paced ventricular event, i.e., a V-pulse generated by a pacemaker. After the prescribed number of such cardiac cycles, e.g., two to ten, a P-V delay in a single cardiac cycle is modified by a first prescribed amount, e.g., 50 milliseconds. The time interval of a V-P interval associated with at least one cardiac cycle preceding the modified P-V delay is then compared to a V-P interval immediately following the modified P-V delay. Only if the difference between the V-P intervals thus measured is less than a second prescribed amount, e.g., 25 milliseconds, is a PMT indicated. If a PMT is indicated, a PMT termination regimen, e.g., extending PVARP, is automatically invoked by the pacemaker (160) for a prescribed number of cardiac cycles, such as one or two cardiac cycles.

Abstract: A battery charging system has a effective pure DC power source charging at least one secondary charge acceptor utilizing an aqueous electrolyte. The applied effective voltage is equal to or slightly greater than the full charge level of said acceptor cell. An impedance/resistance is coupled between the charging means and the secondary charge acceptor cell. The impedance/resistance is a value which reduces any AC component out of the secondary cell to no more than 5% of the total voltage out in order to reduce the counterelectromotive force responsive to the applied voltage. The impedance/resistance is a value which is selected to set the capacitive reactance of the acceptor cell and the inductance reactance of the charging means at levels which reduce the counterelectromotive force of the acceptor cell throughout the full charge cycle in order to produce said cooling affect.

Abstract: An apparatus for controlling ground bounce and transient noise induced in an integrated circuit includes feedback means (74,76) for feeding back to output stages (41', 47') of a buffer (10') input/output power supply bus potentials used for an output driver. Significant noise transients on the input/output upper potential bus (I/O VDD) bring about an increase in the resistance of a series element (76,72) in each output stage (41', 47') and thereby increase the overall switching time of each output stage (41', 47') and output driver combination. Similarly, significant ground bounce voltages on the input/output lower potential bus (I/O VSS) bring about an increase in the resistance of another series element (74,70) in each output stage (41', 47') and thereby increase the overall switching time of each output stage (41', 47') and output driver combination. Increasing the switching time reduces noise transients caused by switching currents. By only increasing the switching time when the noise transients reach a troublesome level, an overall higher data rate is achieved.

Abstract: A data interface is to be produced for conversion between bit-parallel and word-serial data patterns and bit-serial and word-parallel data patterns in conjunction with a parallel computer, in order to accelerate the input and output of data. For this purpose, a three-dimensionally organised data memory (66) with three-dimensional addressing is connected upstream and/or downstream from the parallel processor, in which addressing each address is formed from three components, of which a first component (x) indicates the significance of a bit in a word, the second component (y) the serial number of the word in a string of words and the third component (z) the serial number of the string to which the word belongs. A switching network is allocated to the data memory in order to control the latter. An incoming bit-parallel and word-serial formatted data stream can be temporarily stored in the data memory, where the data from the data memory (66) can be switched as a bit-serial and word-parallel data pattern in the form of "bit levels" (26) with identical bit addresses to a parallel processor (76), and/or a bit-serial and word-parallel data stream organised as a string of "bit levels" which is supplied by the parallel processor (76) can be temporarily stored, where the data can be output as a bit-parallel and word-serial data pattern. <IMAGE>

Abstract: In the case of a known shock absorber, controllable valves are provided on the piston, the force of a spring first having to be overcome in order to open these valves. In the case of this known shock absorber, therefore, it is not possible to produce low damping forces at random. On the proposed shock absorber an additional flow path (106) is formed in the valve device (24), it being possible to open the additional flow path (106) by reducing an actuating force (102). In his way the obtainable damping forces can be greatly reduced. The shock absorber serves for damping the relative movements of two masses and is intended for use on sprung wheel suspension systems of vehicles. <IMAGE>
