Inventor: JOHNSTON JAMES DAVID
IPC: H04N19/94
Filed: 1992-02-13
Abstract: An image-processing system for perceptual coding of images by analyzing one or more images to determine levels of imperceptible noise and encoding a first image to produce encoded values without introducing noise exceeding a determined level of imperceptible noise is disclosed. Analyzing of images is carried out under a set of user determined conditions comprising viewing distance and lighting. The encoded image is communicated and decoded to produce representation of the first image for display. As part of displaying the representation of the first image, a halftoning process is carried out. The halftoning process may comprise the interpolation of data values of the representation of the first image as well as the addition of micro-dither to the representation. Illustrative halftoning techniques include classical halftoning, least-squares halftoning, and error diffusion halftoning. Printer model-based halftoning techniques for both least-squares halftoning and error diffusion halftoning are presented. Applications of the model-based halftoning techniques for systems employing conventional coding of images are also discussed.

Abstract: A configurable self-test circuit for a RAM (102) embedded in an integrated circuit chip comprises an incrementable address register (404), a configurable control circuit (406), a write register (412) and a scanpath (402). The address register stores the current RAM address to be accessed and is adapted to automatically increment the RAM address by an address increment upon receiving an increment signal. The configurable control circuit has a normal operation mode and three test modes wherein all writes, all reads or alternating writes and reads are performed. The write register stores data patterns which are to be written to the RAM under test. The signature generator receives data read from the RAM and produces a unique signature in response thereto. A scanpath through the address register, control circuit, write register and signature generator allows test vectors to be serially shifted in and test data to be shifted out of these devices. A full functional test is performed on the RAM. A special test checks the functioning of the pull-up FETs in each RAM cell.

Abstract: Symmetrical communication portions formed in respective inner surfaces of arms of a lever extend from an inner end surface of a guide groove to an inner peripheral surface of a rotation hole. To connect the lever to the selected housing, the lever is moved parallel relative to the male housing in such a manner that rotation pins move along the respective guide grooves and communication portions until they are rotatably received in the respective rotation holes. Accordingly, there is no need to elastically deform the lever in order to attach the lever to the housing, and therefore, the burden on the operator is small because the two rotation pins are simultaneously guided to the respective rotation holes by the respective guide grooves. Therefore the attaching operation can be carried out easily and positively. After the lever is attached to the selected housing, another housing may be connected to the selected housing also using the communication portions of the lever.

Abstract: The present invention relates to a system and method for filtering a digital signal having a relatively high data rate using circuitry which operates at a lower data rate. The filter includes an input section which receives the input signal and which divides the input signal into a plurality of contiguous segments. The system also includes a first filter which receives samples representing one of the plurality of segments and adjacent samples from the next contiguous one of the segments and which filters all of the received samples to produce a first filtered signal. A second filter receives samples of the next contiguous segment and filters those samples to produce a second filtered signal. The filtered signals are combined by providing the samples of the second filtered signal immediately after the samples of the first filtered signal to produce a filtered output signal. The invention also relates to using respective timing signals associated with the segments to determine when the samples of the first and second filtered signals are provided.

Abstract: Alternate layers of bundles of hollow yarns (5) and conventional yarns (6) are arranged so that the hollow yarns are wavy or straight while the conventional yarns (6) are wavy. The two sets of yarns (5,6) cross over at several points. When the hollow yarns (5) are wavy, the wave is displaced or of greater wavelength. Also claimed is a process where the yarn bundles are wound on a drum with appropriate traverse guides and are then removed from the drum by cutting them transversely in at least one position. 40 Hollow yarns of 150-400 micron diameter and 40 conventional yarns of 21 micron diameter with 14 filaments are wound in 5 groups of each on a drum 120 cm diameter at a speed of 52 m/min to give a 80 mm wide muff. The conventional yarns make about 8 complete traverses per drum revolution while the hollow yarns make less than one traverse per revolution. The muff is cut in several places to give shorter bundles which are then shaped to a circular cross-section.

This grating (11) is formed using a grating array (13) and a mask (14). The second hologram (12) has a plurality of areas each of which records information or image (e.g., ID data) serving as a recording target as an element hologram. The second hologram (12) is formed using a Fresnel hologram serving as a first hologram (15). The first hologram (15) can also be formed using a mask (17) and a diffuser (16) on which ID data is projected. On the hologram (10), information (pattern or image) is recorded with each of reference light components having different directions corresponding to the different small areas. Even if illumination light having a uniform wavefront is irradiated on this hologram, it is difficult to detect all the information (pattern and image).

Abstract: A microkernel interprocess communication subsystem and method provide fast and efficient communication between clients and servers in uniprocessing, multiprocessing, and distributed processing environments. A microkernel operating system includes a capability engine module that manages capabilities or rights to map regions of the memory shared by multiprocessing tasks. There is a wide range of port rights that can be attributed to a task port; various permission levels, security levels, priority levels, processor and resource availability, etc. The capability engine analyses these rights and selectively enables transfers between tasks. In this manner, the capability engine manages the interprocess communication that must take place between the many clients and servers in a Microkernel System, in a fast and efficient manner.
