Patent EP-0324147-A2 (EP)
Inventor: SONEHARA TOMIO
IPC: H04N9/12
Filed: 1988-12-21
Abstract: A light guide type display apparatus has optical fibers (103) that optically couple together a light shutter (104) which serves as an image forming device and a display screen, the optical fibers being effectively interlaced with each other, so that the boundaries between the blocks (101) of the screen are only slightly observable and therefore a uniform and high-quality display is obtained. It is possible to reduce the amount of fibers used and hence lower the cost of the system as well as reduce the size (thickness) and weight of the apparatus by forming a display screen from a plurality of units.

Abstract: In a data processing system having a kernel mode (i.e., for executing privileged instructions) and a user mode of operation, apparatus for responding to interrupt conditions includes a first register (221), subject to the control of the currently executing program for enabling the generation of a mode-related interrupt signal and includes a second register (222) for indicating the presence of a pending mode-related interrupt condition and a third register (223) for requesting a mode-related interrupt be entered in the second register. The mode of operation and the enable and pending interrupt condition registers are monitored (225) and when the signals in the two registers have the appropriate relationship, an interrupt signal is generated to which a control program will respond. The contents of the first register can be controlled by the currently executing program which can control the enabling signal for the currently executing mode. The pending interrupt condition and the request registers may be accessed only from the privileged mode of operation.

Abstract: The method converting bit combinations with a given number of bits into pulse position modulation words, uses a corresp. number of storage elements for serial storage of the bits within each bit combination, with parallel read-out of the storage elements to supply the parallel inputs of a demultiplexer which provides a parallel output bit pattern dependent on the parallel inputs. This bit pattern is fed to a parallel-series converter controlled by a time slot clock signal. Pref. the time slot clock signal is obtained by dividing the bit combination clock signal by a factor corresponding to the number of bits and multiplying by the ratio between the number of time slots and the number of bits.

Abstract: In a system for analyzing a chemical sample by chromatographic separation of said sample into components a method and apparatus are provided for heating the mobile phase to a desired temperature prior to exiting the restrictor (22), while maintaining the density of the mobile phase at a desired level. Such heating and density maintenance being provided by the combination of a restrictor (22) having a minimal taper length (L t ) and a temperature zone (34, 52, 60, 62) immediately prior to the outlet end of the restrictor (22), which temperature zone has a minimum length. A second temperature zone (66, 68, 70) spaced upstream from the first zone, and an intermediate thermally conductive member (56) between the first and second zones can be provided as an alternative embodiment for establishing a thermal gradient. As the mobile phase passes through the second zone, the intermediate conductive member (56), and the first zone, the mobile phase is subjected to a thermal gradient.

Abstract: A technique for enabling a peregrinating Cellular Mobile Radiotelephone (CMR) subscriber to automatically receive, in a foreign service area (that is, an area outside his home service area), calls placed to his MID at his home service area. An FMR processor is coupled through a cable or LAN to a switch associated with the foreign MTSO and is coupled, preferably through a private data network, to a switch associated with the subscriber's home MTSO. Within the FMR processor resides a program that detects the reception at the foreign switch of a predetermined code indicating that calls placed to the roamer's home MID are to be forwarded to the foreign MTSO. Subsequent to the "validation" of the roamer and to the performance of certain software housekeeping tasks, the roamer is assigned a Temporary Directory Number (TDN) for use in the remote service area. The FMR processor then commands the subscriber's home MTSO switch to forward calls, placed to the subscriber's 'MID at the home MTSO, to the TDN. Calls are subsequently forwarded, via the PSTN, from the subscriber's home MTSO to the foreign MTSO.

Abstract: In entropy, e.g., arithmetic or adaptive Huffman, encoding/decoding a context based on prior symbols is needed to provide accurate predictions of symbols to be encoded/decoded. Encoding/decoding efficiency is improved by employing an adaptive context extractor (105). The adaptive context extractor (105) automatically adjusts the configuration of the lag intervals used to define the context. This is realized by adaptively incorporating into the context configuration at least one lag interval found to have a "good" predictive value relative to the particular symbol stream being encoded/decoded. The context configuration adjustment is such that the at least one found lag interval is exchanged with the lag interval currently in an at least one so-called floating predictor position.
