Patent EP-0486145-A2 (EP)
Inventor: FARRELL JOSEPH KEVIN
IPC: G06F13/28
Filed: 1991-10-01
Abstract: An improved multi-channel direct memory access (DMA) controller for data processing systems provides adaptive pipelining and time overlapping of operations performed relative to communication channels. Registers and resources used to pipeline communication data and control signals relative to plural channels are adaptively shared relative to a single channel when command chaining is required relative to that channel. In command chaining a plural word command, termed a Device Control Block (DCB), is fetched from an external system memory via a bus having severe time constraints relative to potential real time requirements of the channels. Pipelining and time overlapping of channel operations, relative to plural channels, increases the effective rate of transfer at the bus interface to the system memory, and thereby allows for the controller to be used for applications in which throughput requirements and bus access constraints could otherwise conflict.

Abstract: A method for enzyme immunoassay for a ligand suspected to be present in a liquid sample includes signal amplification by use of at least two enzymes and a blocked modulator for one of the enzymes. Ligand present in the liquid binds to an antiligand and an enzyme-labeled tracer. The resulting bound fraction is separated and the enzyme in the tracer removes the blocking group from the blocked modulator. The modulator activates or inhibits a second enzyme which catalyzes the conversion of a substrate to a product. The presence or absence of the ligand in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the product. The invention includes a new class of enzyme inhibitors and blocked inhibitors and a kit of materials useful for performing the method of the invention.

Abstract: An on-board navigation apparatus displays characters of name data associated with geographical data in legible order and direction even when the display direction is changed, to north, south, east, and west directions. In operation, after the geographical data and associated name data in a desired region are read, the name reference point P and name area of the read name data is retrieved, and the display direction or orientation of the map is retrieved. Coordinates of a drawing start point Q are then calculated on the basis of absolute coordinate of name reference point P in accordance with the display direction. Correspondence between absolute coordinates of the geographical data and the coordinates of the drawing start point Q of the name data is established, and the name data is written into the name area so that the geographical data and the name data are stored while being superimposed with each other, thereby forming map data. The display is performed on the basis of the map data produced by the superposition.

Abstract: The current limiting element consists of an electrical resistance body (3) which is arranged between two contact connections (1, 2). This resistance body (3) contains a first resistance material which has a PTC characteristic. Below a limiting temperature, the first resistance material has a low cold resistivity (specific resistance) and at least one current-carrying path running between the two contact connections (1, 2). Above the limiting temperature, the first resistance material has a hot resistivity which is high in comparison with its cold resistivity. Such a current limiting element is intended to be distinguished by a homogeneous switching capability and a high rated current-carrying capability, despite simple and cost-effective construction. This is achieved in that the resistance body (3) additionally contains a second resistance material having a resistivity which is between the cold resistivity and the hot resistivity of the first resistance material, and by the second resistance material being fitted with intimate electrical contact with the first resistance material and forming at least one resistor which is connected in parallel with at least one subsection of the at least one current-carrying path. <IMAGE>

Abstract: An apparatus for playback of an optical recording medium (1) where data are recorded after combined calculation of a difference signal and a sum signal generated by detecting reference patterns and the return light reflected from the optical recording medium (1). The recording medium (1) has tracks formed at such a pitch that at least two tracks are scanned simultaneously by a spot of a light beam (12) irradiated onto the recording surface. Each track has reference pattern data composed of wobble pits (B, C) formed at positions deviated from the track center and a multiplicity of pits (A) formed exactly on the track center, wherein the multiple pits (A) and the wobble pits (B, C) are disposed successively. The apparatus comprises an optical detector (25) and a signal discriminator (31). The optical detector (25) has first (25a, 25d) and second (25b, 25c) adjacent light receiving areas divided along the tangential direction of the tracks and serving to receive the return light of the light beam irradiated onto and reflected from the optical recording medium (1). The signal discriminator (31) comprises a subtracter (27d) for calculating the difference between the cutout detection signals of the first (25a, 25d) and second (25b, 25c) light receiving areas, and an adder (27c) for calculating the sum of such output detection signals. The signal discriminator (31) discriminates the recorded data of the optical recording medium in accordance with the result of the combined calculation of the difference signal and the sum signal obtained respectively from the subtracter (27d) and the adder (27c).

Abstract: A test structure and a method of using it for measuring submicron linewidths. Diffraction gratings are made with lines having an unknown linewidth. The grating has a pitch comprises of multiple lines and multiple surfaces. This permits a wider "effective pitch", resulting in an increased number of observable diffraction orders. Each order provides an intensity measurement, which can be substituted into a diffraction intensity equation in which intensity is a function of linewidth and other unknown variables. At least as many intensity measurements are obtained as are unknown variables so that a system of equations can be solved for the linewidth. In practice, if the grating lines are made in the same manner as other lines of a product, the width of the latter can be inferred.

Abstract: Described is an ink-jet type recording head including a nozzle plate (2) provided with nozzle openings (2a), a spacer (1) provided with partitions for partitioning pressure generating chambers, ink supply ports and reservoirs, and a plate member (3) which are sandwiched and fixed together. Displacement of the plate member (3) is produced by piezoelectric vibrators (4) to thereby generate ink droplets. The spacer (1) is formed by anisotropic etching of a silicon single crystal substrate so that the pressure generating chambers, the ink supply ports and the reservoirs are formed as through-holes communicating with each other. Accordingly, etching conditions for the respective through-holes are made equal to each other. Particularly, through-holes small in sectional area such as the pressure generating chambers and the ink supply ports can be formed with a high accuracy.

Abstract: Previous efforts to measure polarization dependent loss of optical components have been limited in uncertainty to more than 0.01 dB. This is because the power meter used in a test set contains polarization dependent loss which adversely affects the final readings. It is here disclosed that an unpumped erbium doped fiber (36) can convert a received polarized signal into unpolarized amplified spontaneous emission of a longer wavelength if the fiber is of sufficient length to absorb the received signal. By locating the inventive unpumped erbium doped fiber upstream of the power meter (38) of a test set, the polarized signal to the power meter is converted to an unpolarized signal and, therefore, the polarization dependent loss of the power meter can not influence the measurement obtained.
