Abstract: The present invention refers to a device for the ascent and descent of staircases for the disabled. 
     The device comprises a lifting structure, equipped with a standing or seating platform which is maintained in a constantly horizontal position, and is also equipped with a pair of rolling elements (3) and (4) which couple with tracks (1) and (2) by means of a cogged fit; each rolling element is accompanied by a bogie (5) and (6) which rotates around the same axle as the rolling element and which runs along the bottom edge of the tracks in such a way as to ensure the stability of the lifting structure; for the greater stability of the lifting structure, rollers (15) are fitted, which move along auxiliary tracks (16) which are mounted along certain tracts of the track; for the same reason pawls (18) are fitted, which prevent oscillation of the bogie along horizontal tracts, and thus prevent unwanted oscillation of the lifting structure under   any circumstances. The device is equipped with an on-board motor and is able to move the lifting structure along tracts of variable gradient and around very narrow bends.

Abstract: In a digital multiplier for multiplying two multi-bit binary operands to produce a binary result by means of a lookup table containing all possible products of said operands, reduction of the total amount of memory required to store the table is obtained by segmenting one operand into a plurality of non-overlapping bit groups and constructing lookup tables for the bit groups, in which each lookup table contains products of its associated bit group and the other, non-partitioned operand. Multiplication is accomplished by generating partial products from the lookup tables, shifting the partial products to account for the relative significance of their associated bit groups, and adding the partial products to provide the resultant product.

Abstract: A supply circuit (40) providing an intermediate voltage between Vss and Vcc for a DRAM is coupled to both the cell capacitor plates and the bit line clamp transistors. The supply circuit includes a logic circuit (42) which ANDs the equilibration signal and a restore complete signal thereby to provide a timing signal in the initial portion of the precharge epoch. The timing signal turns on first and second transistors (46, 44) which operate as a load to develop a voltage at first and second nodes (45, 47). The voltage so developed is a transition voltage above the target holding voltage. This voltage is stored on a storage capacitor (52), coupled to the gate electrode of a drive transistor (50) and transistor (44). The drive transistor selectively couples operating voltage (VCC) to the hold line (22). After the logic circuit turns off, the offset voltage which has been stored on the capacitor (52) controls the drive transistor (50) to couple the target holding voltage to the holding line.

Abstract: At least one bolt of the rifle has a movable safety catch part (14) which engages over the sear bar (3) in the safe position (14.1), so that it is unable to jump out of the notch (5) on the sear (6). The safety catch part (14) is mounted so as to pivot about an axis (13) which is parallel to the bar axis (16) and is acted upon in the pivoting direction by the force of a spring (15.1) which holds the safety catch part (14) out of engagement on the sear bar (3). The force of the spring (15.1) and the moment of inertia of the safety catch part (14) about its pivoting axis (13) are such that the recoil force exerted by a shot which has been made temporarily pivots the safety catch part (14), by virtue of its inertia, against the force of the spring (15.1) into the safe position (14.1). <IMAGE>

Abstract: A constellation (12) of satellites (14) which are distributed around the earth serves as a communications infrastructure (12) that supports autonomous position determination and reporting of that position to a remote location (28). Subscriber units (30) are remotely programmed to activate upon the occurrence of an activation event (120) and to record an itinerary (244). In an intelligent tracking embodiment, reporting of position occurs only when a current position deviates from the itinerary (244). If subscriber units (30) can engage in activities (144) which lead to determining their position, they cooperate with the infrastructure (12) to determine their positions. To determine position, location pulses may be transmitted on a regular schedule (106, 144). Location pulses are transported between a fast moving satellite (14) and a subscriber unit (30). Relative movement causes different location pulses to have different propagation delays and Doppler characteristics. By analyzing changes in propagation delays and Doppler characteristics, a procedure (170) determines a position for a subscriber unit (30).

Abstract: Disclosed is a system (100) which compiles instrument commands (202) from a test instrument programming language, along with data in the commands, into a machine usable form (302). The machine usable instructions (302) thus sent to the instrument are significantly smaller than the original human readable ASCII characters of the source language, and the machine usable form (302) of the commands avoids additional parsing in the instrument. During the compilation process (216), all parameter data being sent to an instrument is placed into a single data structure, which reduces the number of parameters passed between the test software and any device drivers used to access the instrument.

Abstract: A shorter wavelength light generating apparatus consists of a semiconductor laser (42) for initially radiating various mode of coherent light including a required mode of coherent light, a reflection type of diffraction grating (50) for diffracting and reflecting the various modes of coherent light to selectively feed back the required mode of coherent light to the semiconductor laser which is induced by the coherent light fed back to dominantly radiate the required mode of coherent light, and an optical waveguide type (46) of wavelength converting device for converting a part of the required mode of coherent light radiated from the semiconductor laser into shorter wavelength light. The required mode of coherent light not converted is radiated to the diffraction grating. Accordingly, even though the various modes of coherent light are initially radiated from the semiconductor laser, the required mode of coherent light is dominantly radiated from the semiconductor laser after a short time. Therefore, the shorter wavelength light is stably output while stabilizing the wavelength of the shorter wavelength light.

Abstract: This invention provides a system capable of performing compatible transmitting and receiving processes, regardless of whether a TV signal on the transmission side is a high-resolution signal or a low-resolution signal or of whether the reception side is a high-resolution display unit or a low-resolution display unit. On the transmission side, a frequency division circuit (150) divides a high-resolution TV signal into signals in a plurality of frequency bands. The signals in each frequency band are converted into signals of a horizontal and vertical low band (a low-resolution TV signal band). The converted signals are coded by coding units (110-113), which transmit the coded signals. On the reception side, the coded signals multiplexed on the transmission side are separated and decoded at decoding units (202-205). A frequency synthesizing circuit (220) restores the frequency bands of the decoded signals to the original bands. Then, the resulting signals are displayed with a high resolution. A low-resolution signal is coded and then transmitted. The coded signal is decoded on the reception side. The decoded signal is interpolated at an interpolation circuit (270). The interpolated signal is then displayed on a high-resolution display unit.
