IPC: H04L12/40
Filed: 1992-10-19
Abstract: ABSTRACT OF THE DISCLOSURE       In the transmission of variable length data blocks, where data and addresses share the same bus lines, one of the other signals, which are present anyway (chip-select, CS-, read, write), indicates the block length.  The first time slot following the setting of this signal is designated for an address (starting address), all subsequent time slots are designated for data, until the signal is reset.  In this way, the length of the data block need not be known at the beginning of the transfer.

Title: Method and apparatus for adaptively reducing interline flicker of tv-displayed image
Inventor: PARULSKI KENNETH A
IPC: H04N5/44
Filed: 1992-03-11
Abstract: METHOD AND APPARATUS FOR ADAPTIVELY REDUCING INTERLINE   FLICKER OF TV-DISPLAYED IMAGE            ABSTRACT OF THE DISCLOSURE          An image analysis and flicker filter control mechanism is incorporated into the image processing software of a photofinishing workstation for the purpose of analyzing the high frequency content of the image. As a result of this analysis, there is stored on a write once optical compact disc, in the header field associated with each image, an interlace "flicker code" representative of the extent, if any, to which the vertical dimension of the image is to be subjected to a low pass filtering operation in the course of reading out the image from the disc for application to a playback device, such as a raster scan TV display. The flicker code may be a binary value code or a multiple bit value controls the degree of vertical lowpass filtering of only those images which exhibit interlace flicker, and only during playback onto interlaced TV displays, thereby reducing the flicker of an image reproduced by an interlaced TV display without reducing print sharpness.

Patent CA-2084317-A1 (CA)
Inventor: JACKSON NORMAN C
IPC: B29C45/14
Filed: 1992-12-02
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method for molding composite automotive trim members having a layer of a first material and a backing member made of a second thermoplastic material. The first material is introduced to the mold in the form of an elastic sheet having a show surface. This sheet is placed in the mold and the second thermoplastic material is subsequently injected into the mold cavity. This causes the second tnermoplastic material to bond to one side of the sheet and forces the show surface on the opposite side of the sheet into abutting engagement with the mold surface, thereby creating the trim member. The second thermoplastic material forms a backing member that provides structural support for the sheet. The sheet forms an outer layer for the trim member. Note that the show surface on the sheet remains intact during and after injection and therefore provides a show surface for the trim member.

Abstract: OPTICAL VIEWING DEVICE          Abstract of the Invention:    A low cost optical viewing device for viewing a remote location comprises three sections of an objective lens, relay lens and eye piece.  However, in contrast to prior art optical viewing devices, all three sections of the present invention are free of conventional and relatively expensive glass rods.  The preclusion of the glass rods leads to an overall lower cost (e.g., disposable) optical viewing device (e.g, borescope and endoscope).  In addition, the optical viewing device of the present invention achieves lower cost by the use of a combination of molded plastic lenses and glass lenses.  In accordance with still another important feature of this invention, the method of illuminating the remote location to be viewed is accomplished by using low cost plastic optical fibers which are twisted so that the field of illumination is increased and may be tailored to match (or be no less than) the size of the field of view of the optical viewing device.  Still another significant feature of the present invention is its low weight as compared to prior art devices.  This low weight is obtained both through the use of the combination of lightweight plastic lenses and glass lenses as well as by the fact that the lenses are separated by an air space (as opposed to heavy glass rods).          This light weight feature of the present invention leads to ease of manipulation by the end user.

Abstract: ABSTRACT OF THE DISCLOSURE           A level vial assembly for use in a carpenter's or mason's level.   The assembly includes a vial mounting subassembly to be mounted in a level body, consisting of at least a vial holding plate and one or more vials which are mountable therein, and one, or preferably two, bezel-lens subassemblies  for  protecting  the  vial.    The  vial  is positioned  in  the  mounting  plate  between  a  pair  of oppositely directed notches, and is held in position by a tab which extends outwardly from the side of the vial and bears against the holding plate.  The tab limits lateral movement of the vial in one direction.  The holding plate is mountable within an aperture in the level body.   The bezel-lens subassemblies are mountable in the level body aperture on opposite sides of the vials.   One of the bezel-lens  subassemblies  includes  vial  support  means adapted  to  bear  against  the  vial  to  prevent  lateral movement in another lateral direction.   The level vial assembly can be easily and precisely mounted to a level body, resulting in a high-quality product at a reasonable cost of assembly.

Abstract: A self-routing crossbar switch interconnects a plurality of processors with a plurality of memory modules.          In a self-routing crossbar switch connecting N processors and N memory modules, a processor is connected to each input port and a memory module is connected to each output port; each of the N processors can transmit a memory request simultaneously provided that there is no port contention and no bank contention.  Port contention occurs if two or more processors attempt to access the same output port of the self-routing crossbar switch at the same time.  The memory module consists of several memory banks that are connected in an interleaved manner.  If the memory bank is accessed before it is ready to accept a new request, bank contention is said to have occurred.  In the self-routing crossbar switch the requests directed to a port are first passed through an aligner and a conflict resolution logic.  There is one aligner associated with each output port.  The aligner inputs the requests directed at an output port and aligns them so that, at the output of the aligner, all the active requests appear in a consecutive fashion.  The conflict resolution logic resolves the port and bank contention.
