Abstract: Method and apparatus for correctly predicting an outcome of a branch instruction in a system of the type that includes a Branch History Table (BHT) and branch instructions that implement non-explicit subroutine calls and returns. Entries in the BHT have two additional stage fields including a CALL field to indicate that the branch entry corresponds to a branch that may implement a subroutine call and a PSEUDO field. The PSEUDO field represents linkage information and creates a link between a subroutine entry and a subroutine return. A target address of a successful branch instruction is used to search the BHT. The branch is known to be a subroutine return if a target quadword contains an entry prior to a target halfword that has the CALL field set. The entry with the CALL bit set is thus known to be the corresponding subroutine call, and the entry point to the subroutine is given by the target address stored within the entry. A PSEUDO entry is inserted into the BHT at the location corresponding to the entry point of the subroutine, the PSEUDO entry being designated as such by having the PSEUDO field asserted. The PSEUDO entry contains the address of the returning branch instruction in place of the target address field.

Abstract: The present invention relates to a technique for decomposing any simple or complex arbitrary polygon into a trapezoid parallel to the scan direction for more efficient scan conversion by rasterization circuitry. An input polygon is split into "slabs", which are adjacent regions bounded by lines parallel to the scan direction (FIG. 3). Initially the polygon is split at the y coordinate of every vertex to define the slabs. Then, for each slab, it is determined which edges are present in the slab and whether there are any unacceptable edge intersections. If an unacceptable edge intersection [if]  is  found in a slab, that slab is broken into two or more slabs at the y coordinates of the intersection points of the edges. Each of the slabs [are]  is  then processed independently. Once no unacceptable intersections are found in any slab, trapezoids are rendered from adjacent pairs of edges and sent to the rasterization circuitry. Since edge intersections may be accounted for in accordance with the invention, any input polygon, no matter how complex, may be correctly rendered in an efficient manner.

Abstract: An elevator cab assembly is provided with a rail guidance system which provides a substantially vibration-free ride despite uneven passenger loading. The guidance system includes side-to-side and front-to-back rail guide rollers which are adjustably mounted on the cab frame. The rail guide rollers are pivotally mounted on links which are spring-biased toward the guide rail blades. Stops are provided on the links to limit the extent of permissible pivotal movement of the rollers away from the guide rail blades. Actuators are connected to the link springs to selectively increase the spring pressure acting on the links when the pivot stops are engaged as a result of uneven passenger loading in the cab. The actuators ensure that the roller links do not ride against the stops, thereby ensuring a continuous spring biased engagement between the guide rollers and the guide rail blades, and a substantially vibration-free ride.

Abstract: A plurality of AC/DC converters (11) connected in parallel, are provided in which any one of the power converters can fail with-out affecting the operation of the machine which the plurality of converters are providing power. The failed AC/DC converter can be removed and replaced by another converter without shutting down the system. The output voltage of each converter is sensed on the power supply side of a decoupling diode (17, 19, 21). This allows each one of the converters to operate with its own sense loop (25, 27, 31, 33, 35, 41, 43) and, therefore, the feedback loop does not open when a converter is removed and another used in its place. Via power limit circuit (45) each of the parallel connected AC/DC converters (11) is designed to provide a preset maximum power which is independent of AC line voltage variation. To limit the power, the control voltage is made inversely proportional to the average input AC line voltage. The output voltage of the AC/DC converter is made to vary as a function of the load. This allows all the converters in parallel to provide power to the load all the time.

Abstract: An apparatus and method for capturing an image, using a spatial light modulator (SLM) 11 and a single-element sensor 15. The SLM 11 is an array of individually switchable pixel elements, which reflect light toward the sensor if switched to an "on" position. As each pixel element is switched on, light from that pixel element is directed to the sensor 15. For each pixel element, the sensor 15 generates a signal proportional to the light associated with that pixel element, the result being a series of signals representing at least one image frame. The process may be repeated for a number of image frames for generating moving pictures. The SLM is a deformable mirror device.

Abstract: Various steering coefficients (KB, KC, KG) are decided in accordance with a detected car speed (V), while a correction amount (X) and a correction factor (Y) are determined by fuzzy reasoning in accordance with a detected road surface friction coefficient (µ), road surface gradient (α), and lateral acceleration (G). A reference in-phase steering amount (δ RB), equal to a product of a reference in-phase steering coefficient (KB) and a detected steering wheel angle (ϑ H), is corrected by an inphase correction steering amount (δ RC), which is equal to a product of an in-phase steering coefficient (KC) and the detected steering wheel angle (ϑ H), with a delay determined by a time constant (T) calculated from the correction amount (X), to thereby determine a corrected in-phase steering amount (δ R). A corrected anti-phase steering amount (δ G), obtained by multiplying a reference anti-phase steering amount (δ GB), equal to a product of the anti-phase correction coefficient (KG) and a detected steering wheel angular velocity (ϑ HA), by the correction factor (Y), is added to the corrected in-phase steering amount (δ R), to thereby obtain a rear-wheel steering amount (δ) on which the rear wheels are so steered as to match the road surface friction coefficient, road surface gradient, and lateral acceleration.

Title: Disconnection device for surge arresters
Inventor: BIEGELMEIER GOTTFRIED PROF ING
IPC: H02H9/04
Filed: 1992-01-15
Abstract: A disconnection device for surge arresters has a current-interrupting device which is suitable for interrupting the fault current once the voltage-dependent resistor in the arrester becomes conductive as a result of aging or overloads. This fault current flows through the common earth line of the associated arrester, which line forms the primary winding of a straight-through transformer which is built into the disconnection device. The secondary winding is connected to an electronic energy storage circuit which is independent of the mains voltage. A converter relay is operated by this energy storage circuit in a pulsed manner when a fault current of predetermined intensity flows to earth through the earth line. The converter relay can be either a monostable or bistable electromechanical relay, or an electronic relay (e.g. a thyristor circuit). When the relay contact is closed, an electromagnetic trip device (latching trip device) is operated by the energising current taken from the mains, which trip device trips the latching mechanism of the current interrupting device. Thereafter, the monostable converter relay reverts back to its original position again, or the bistable converter relay is mechanically or electrically reset to its original position, as a result of which the relay contact opens and the disconnection device is ready to switch on again via an operating device.
