Patent EP-0486060-A2 (EP)
Inventor: RUSSELL JAMES T
IPC: G11B7/085
Filed: 1991-11-15
Abstract: Apparatus and method are disclosed for encoding information and recording same as sets of variably spaced related marks stored in wavelength (color) and/or depth selective layers on an optical record (10). The encoded information is read by illuminating each set of such recorded marks selected by wavelength (color) or focal depth with a coherent read light to cause an optical interference pattern (14) consisting of a varying distribution of amplitude maxima separated by amplitude nulls (or minimas) that change in accordance with the encode information. This read interference pattern (14) is detected by photosensing diode arrays (26) and after decoding, the system outputs an information signal representing the original information.

Abstract: A method and apparatus for interpolating pixels to be displayed on a display screen so as to account for the nonlinearity of distance changes in the perspective projection of a 3-D object onto the display for corresponding linear distance changes in 3-D world space. Each pixel (X, Y, Z) of an input polygon to be displayed on the display screen is given a perspective value (W) in world coordinates for each display point, and this value is passed through the graphics processor (200) along with the shading parameters (R, G, B, etc) associated with the each display point. The respective shading parameters (R, G, B, etc) for each display point are then scaled by the perspective value (W) for each display point to account for the effects of perspective foreshortening of the displayed object on the display screen. Since no translation to world coordinates is required for the perspective scaling, fast hardware circuitry may be used. The rendered image of the invention has much improved color accuracy since the shading more closely reflects the effects of changing perspective in world space.

Abstract: An object (14) which is to be implanted with ions is enclosed in a container (12). A plasma (44) is generated in a chamber (26) which is separate from, and opens into the container (12). The plasma diffuses from the chamber (26) into the container (12) to surround the object (14) with uniform density. High voltage negative pulses are applied to the object (14), causing the ions to be accelerated from the plasma (44) toward, and be implanted into, the object (14). Line-of-sight communication between a plasma generation source (30) located in the chamber (26) and the object (14) is blocked, thereby eliminating undesirable effects including heating of the object (14) by the source (30) and transfer of thermally discharged material from the source (30) to the object (14). Two or more chambers (26,34) may be provided for generating independent plasmas (44,46) of different ion species which diffuse into and uniformly mix in the container (12). The attributes of the different plasmas (44,46) may be individually selected and controlled in the respective chambers (26,34).

Abstract: A method to compress, store, and retrieve bibliometric information on multiple sources of text is presented. The compression consists of 2 parts, and may use any one of the many ordering-based bibliometric laws for sources of text. The first compression part comprises of the storage of bibliometric information on the items from a text source, using the rank of the items in the ordering relation as defined in the bibliometric law as an indication of the bibliometric information. The second compression part efficiently uses pointers and tables to get rid of redundant information. As an application, a posting compression method is presented for use in term weighting retrieval systems. The first compression uses a postulated rank-occurrence frequency relation for the document in question that has as only variable the document's length, for example Zipf's law that states that the product of rank and frequency is approximately constant. The second compression part efficiently uses pointers and a few tables next to the principal storage. The compression makes use of direct random addressability. All postings relating to a particular document may be stored together, allowing easy expendability and updating. With respect to conventional technology, storage requirements is roughly halved.

In addition, the seat assembly includes many features found in current production seat assemblies such as a fore and aft adjuster, an adjustable lumbar support (202), a seat cushion lift means and a seat back recliner. While reinforcing the seat structure, care has been taken to efficiently manage the seat belt loads without adding unnecessary structure and weight to the seat assembly.

Abstract: 5 n7 A multi-processor system having mirrored memory units accessible by either processor. The term "mirrored memory" in the context of the present invention describes the ability of each of the processors to directly READ and WRITE the contents of its own local random access memory (RAM) unit and in the local RAM unit of the other, remote processor. The mirrored memory of the present invention comprises two units of triple-ported RAM, each unit interconnected by a pair of interprocessor busses to the corresponding triple-ported RAM of the remote processor. "Triple-porting" describes the three input/output ports available for accessing a RAM unit. An internal port is used by a processor to access its local RAM, while the other two ports are provided so that the same RAM can be accessed by the remote processor through the paired interprocessor busses. Each processor may READ or WRITE its own local RAM, the remote processor's RAM, or both RAM's during a single operation. The present mirrored memory design facilitates concurrent and independent execution of both processors of a pair. Concurrent execution of both processors during mirrored RAM accesses is possible because the interprocessor busses are configurable as virtual dedicated ports (one for each processor). A method is also provided for equalizing the mirrored memory units of paired processors.
