Abstract: A non-intrusive DC current monitor is presented which emulates the theoretical operation of an AC transformer. A conductor (10), carrying the current to be measured, acts as the primary of a DC current transformer. This current is passed through the center of a secondary coil (12), and core positioned thereabout, and produces a magnetic flux which induces a current in the secondary proportional to the current flowing in the primary. Means (20, 22) are provided to periodically "reset" the transformer core such that the measurement inaccuracies associated with core saturation are obviated. A reset current is caused to periodically flow through the secondary coil which produces a magnetic flux oppositely polarized to the flux created by the current in the primary, thus allowing ongoing measurements (14) to be made.

Abstract: A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes. The instruction set is limited to register-to-register operations and register load/store operations. Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions. The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes. By providing a conditional move instruction, many short branches can be eliminated altogether. A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken. Another performance improvement makes use of unused bits in the standardsized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like. The target can thus be prefetched before the actual address has been calculated and placed in a register. In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed. The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used. A granularity hint is added to the page table entry to define the page size for this entry. An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Abstract: The present invention relates to a system and a method for sharing software modules which are part of a computer program, and which have been previously loaded into a private area (104) of main memory (102) of a computer. The addresses of software modules which remain loaded in the private area (104) after an execution of the computer program are kept track of. When a subsequent execution of the computer program requires a software module which has remained loaded in private area (104), the address of the software module is obtained, and the computer program branches to that address.

Abstract: A novel method for measuring distances by determining the transit time of laser light pulses which are sent out by the range finder and reflected back to the measuring device from targets hit, is based on the fact that the measuring cycle is divided into time intervals and that the arrival or non-arrival of a reflected light pulse is registered in each time interval. An arrangement for carrying out the method is distinguished by the fact that, instead of adding counter chips, a serial memory is provided into which the clock of an oscillator is entered coded with the information as to whether a reflected light pulse has arrived within the time interval. <IMAGE>

Abstract: Disclosed herein is an arrangement for shielding individual electronic units from undesired microwave or millimeter wave radiation while providing a means of transferring input and output signals and operating power through the shield wall. A metal box encapsulates an electronic unit. Input and output signals are fed into and transferred from the electronics unit through the shield wall using optical links and photo transmitting and receiving components. Power is transferred through the shield box wall using piezo crystals secured to the outside and inside of the shield box wall and a dielectric rod connected between the two piezo crystals through a hole in the wall. Electrical energy therefore can be transferred into mechanical energy transferred through the box wall to the piezo crystal within where it is received and transferred back into electrical energy. Accordingly, metal feedthroughs are not needed, eliminating any paths for radiation to enter the shield box.

Abstract: An image reading method and apparatus are capable of high-quality reading of a transparent original with an optimum light quantity by maintaining both a transmitting light source unit for emitting light for reading the transparent original and a reading scanner of an image reader for receiving the transmitted light at an adequate relative position to keep their optical axes in alignment during scan reading. Such alignment is achieved by providing synchronization in scanning speed by placing either one of the transmitting light source unit and the reading scanner at an arbitrary selected position, scanning the proximity of the selected position with the other, determining a light quantity distribution, determining a synchronous position from the distribution, carrying out such synchronous position detection at two or more distinct positions, and calculating the scanning speed ratio of the transmitting light source unit to the reading scanner from the result. Alternatively, alignment is achieved by carrying out similar synchronous position detection, determining the relative spacing between the base points of said transmitting light source and said reading scanner from the distances from the respective base points to the synchronous position, and matching the scan start positions of the transmitting light source unit and the reading scanner in accordance with the relative spacing.

Abstract: In a digital-to-analog converter, a digital input signal of x bits is subjected to digital-to-analog conversion with at least two of x bit positions recognized as a common bit position and converted into analog levels of a number which is different from 2 x  where x is an integer. At least one additional common bit position may be selected from the x bit positions except the common bit position. The digital input signal may be pre-processed by the use of a logic circuit (15) prior to the digital-to-analog conversion so as to control the number of analog levels. The digital-to-analog converter is applicable to a modulator which produces a quadrature amplitude modulated signal having a circular arrangement of signal points on a phase plane. A demodulator comprises an analog-to-digital converter for converting the above-mentioned analog signal into a reproduction of the digital input signal.
