Abstract: A serial-bit digital processing system uses registers and latches to synchronize samples and justify sign-bits. Nominally each processing block in the system includes a sign extend register (16) preceding an arithmetic element (18) and an output register (20) following the arithmetic element. Input registers of one arithmetic element may merge with output registers of the preceding arithmetic element. The sign extend registers include a serially coupled latch which is selectively controlled to pass serial sample bits or to replicate the sign bit. The respective registers are clocked with one of two clock signals (CLOCKN, CLOCKP) having different numbers of pulses per sample period and the length of the respective registers are selected so that at the terminus of each sample period the bits of each sample in the processing system are appropriately justified.

Title: Scanning apparatus and method
Inventor: THORESON ROBERT J
IPC: H04N1/00
Filed: 1987-04-28
Abstract: A scanner and scanning method for scanning a sheet such as a chart. The scanner includes scanning means and detection means. The scanning means includes means for supporting and mounting the sheet, and illumination means for directing light onto an illuminated area of the sheet, the illuminated area being elongated along a scan direction. The scanning means also includes means for causing the illuminated area to move across the sheet in a movement direction normal the scan direction. The detection means comprises a photodetector array and a coherent fiber optic bundle. The coherent fiber optic is tapered, such that it has a comparatively wide aperture adjacent the illuminated area, and a comparatively small aperture adjacent the photodetector array. in a related aspect, the illuminated area is caused to move in a first direction across the sheet such that the illumination means sequentially directs light onto a series of pixel areas of the sheet. The color of the light is varied such that as the illuminated area moves across the sheet in the first direction, the color of the light alternates between first, second and third illumination colors, thereby alternately illuminating the pixel areas with the illumination colors. An illumination color signal is produced for each pixel area. The processing means detects light reflected from each pixel area to produce an intensity signal, and color processing means combines the illumination color and intensity signal for each pixel area with the same signals from two adjacent pixel areas, to provide a pixel color signal representing a composite color for the pixel area. Means are provided for processing sequences of pixel color signals to eliminate transition colors.

Abstract: Metals from Groups I and II of the periodic table are commonly used to initiate the polymerization of conjugated diolefin monomers into polymers. The polymers formed in such polymerizations are terminated with the metal used to initiate the polymerization and are sometimes referred to as living polymers. Reactive end groups can be affixed to the chain ends of such polymers by utilizing the process of this invention. Such reactive end groups can subsequently be reacted with the backbone of other polymer chains. This results in the formation of a polymer having a reduced number of dangling chain ends. The functionalizing agents which can be utilized in the preparation of such polymers include hexachlorocyclopentadiene, tetra­alkylthiuram disulfides, and chlorinated phenyl fulvenes.

Abstract: The connection element consists of a thin metal strap having anchor elements on the bearing faces. The anchor elements are claws projecting at right angles, which are butt-welded to the plate or punched from the strap and have a tip at the end face. They are set by driving in with planarity and are universally usable, e.g.: - as wall anchors for fastening cellular-concrete wall construction parts to steel or reinforced concrete columns;  - as dowelling elements for roof and ceiling construction parts; - as means for the partial fixing of roof and ceiling construction parts to the centre support to reduce deflection;  - as anchoring means for ring beams and - as cavity-wall anchors in two-leaf cavity wall construction with cellular-concrete wall blocks or wall construction parts.   The connection element according to the invention opens up new avenues in cellular-concrete construction using the dry construction method, which contributes considerably to more rapid construction progress without waiting times, to a rationalisation and hence to improved efficiency. <IMAGE>

Abstract: Known electrical apparatuses for the continuous control of the operating voltage, used instead of electrical installation switches, as apparatuses mounted on or beneath the plaster in each case for switching individual circuits. When replacing known two-circuit switches, which are used for mutually independently switching two separate circuits on and off, two electrical apparatuses are required in each case, termed dimmers. This requires additional installation space which is not always available. A new electrical apparatus for the continuous control of the operating voltage of electrical loads, especially of lamps, is designed so that two electronic switch parts (22, 23) are placed therein and can be controlled by two rotary potentiometers (24, 25), which are arranged axially adjacent to one another and have concentrically arranged axes of rotation (26, 27). A preferred field of application is domestic electrical installations. <IMAGE>

Abstract: In an industrial vehicle having at least first and second arms (OA,AB) rotatably coupled to each other, a locus depicted by a tip of the second arm during rotation of the first and second arms is controlled. An amount of positional deviation of the tip of the second arm in the direction (compensating direction) perpendicular to the direction of the targeted locus (operating direction) is detected. A command value for the compensating velocity is determined from a command value for the operating velocity and the deviation. The driving of the first and second arms is controlled by the two velocity command values in the operating and compensating directions in such a manner that the tip of the second arm moves along the targeted locus. In short, positional feedback is provided by means of the positional deviation in the direction perpendicular to the targeted locus. In addition, the direction of the targeted locus is set as the direction of installation of an operating attachment mounted on the tip of the second arm. In an industrial vehicle further having a third arm, the second and third arms (AB,BC) are driven in such a manner that the tip of the third arm will not deviate from the targeted locus as a result of the rotation of the first arm. At this juncture, the aforementioned feedback is also provided.

Abstract: In the interest of ease of manufacture, hybrid lasers of distributed-Bragg-reflector type are preferred for use as light sources in optical communications. We have found that such lasers are prone to mode instabilities which can adversely affect the error rate. However, they can be made to operate away from mode instabilities by adjusting a laser parameter such as e.g., laser temperature, thereby assuring highly error-free transmission. Alternatively, by making the reflectance peak of the Bragg reflector (22,23,24) sufficiently wide that it is capable of supporting two or more modes of optical radiation it is possible to render mode instability of negligible influence on error rate, provided that mode dispersion is not a problem.
