Patent EP-0422468-A2 (EP)
Inventor: PEPPER DAVID M
IPC: H01S3/23
Filed: 1990-09-28
Abstract: An optical input (18) beam is transmitted through a non-linear medium (12) capable of two-wave mixing gain by photorefractive, Brillouin, Raman, or other non-linear optical mechanism. A pseudo-conjugator (16) retroreflects the input beam which has passed through the medium, back into the medium. The retroreflected beam acts as a seed, which lowers the threshold for producing a self-pumped conjugate reflected beam in the medium by stimulated scattering. The pseudo-conjugator may be a flat array of retroreflecting elements in the form of spheres or corner reflectors. A mosaic pattern of conjugating elements can be phase-locked to yield larger apertures and/or energy scaling, in a master-oscillator, power-amplifier (MOPA) (80), (90), or a four-wave mixer (FWM) (120) configuration. The retroreflected beam can be modulated to temporally encode information onto the conjugate beam, and/or polarized to increase the system efficiency. The input and self-pumped conjugate reflected beams can be used as reference or pump beams in a FWM configuration.

Abstract: A method and apparatus for controlling the reciprocation of a movable mirror of an interferometer used in an interferometric spectrophotometer are disclosed, wherein a frequency dividing ratio corresponding to a desired reciprocating speed of the movable mirror is set and then a pulse signal from an oscillator is divided at the frequency dividing ratio for producing a frequency-divided signal which in turn is compared with an interference signal from a control interferometer to produce an error signal for controlling the reciprocating speed of the movable mirror based on this error signal until the desired reciprocating speed is reached. Preferably, the frequency dividing ratio can be varied by a central processing unit, for example, so that the user is able to freely change the reciprocating speed of the movable mirror to conform to the type of a detector used, thereby enabling a measurement under optimum conditions.

Abstract: A communication system has a first node which transmits on a data bus (26) messages each having a preamble having a predetermined format including a message type (10) and the message length (12), and a plurality of second nodes receiving messages from the data bus (26) and including elements (42,43,45,55,48) which can determine that the preamble in each message has the predetermined format. The preamble is particularly useful for allowing the second nodes to quickly detecting messages not directed to those nodes of which the elements form a part, allowing the node to ignore the remainder of the message. This allows the individual nodes to exclude the message interpretation for detecting messages directed to them, from their processing tasks thereby improving the effective processing speed of the network.

Abstract: A sputtered low copper concentration multilayered device interconnect metallurgy structure is disclosed herein. The interconnect metallurgy is seen to comprise a four-­layer structure over an interplanar stud connection (10) surrounded by an insulator (8) to make connection to a device substrate (6). The four-layer structure consists of an intermetallic bottom layer (12′) typically 700Å thick and, in a preferred embodiment would comprise TiAl₃. 
     Above is a low percent (< 2%) weight percent copper, aluminum-copper, conductor layer (14). At the end of the process, this layer (14) is typically 8500Å thick and consists of a compositon of 99,5% aluminum and 0,5% copper (aluminum-0,5% copper hereafter). Over said con­ductor layer (14) is a second intermetallic layer (16′) of the same thickness and composition as the first intermetallic layer (12′). Finally, a top layer (18) of aluminum-0,5% copper (or pure aluminum) of approximately 100Å to 500Å thick achieves the structure.

Abstract: Apparatus and method for optimizing bus arbitration during direct memory access (DMA) data transfers across a nondedicated bus between a memory and/or a plurality of external devices each master having an arbitration priority. At least two nonoverlapping clocks are provided per transfer cycle and there is at least one transfer cycle per arbitration cycle. Arbitration priority requests are transmitted from each external device to an arbitration bus only at the rise of the first clock. At the end of the last clock, the priority code of the external device having the highest priority is determined to designate the external device which is to become bus master. Addresses and data are transferred between the designated bus master and the memory or another of the external devices via the nondedicated bus during the next cycle after a then active bus master relinquishes control. The priorities of the external devices can be changed dynamically. 
     Arbitration cycles are pipelined in such manner that there is no loss of address or data transfer cycles. The then active bus master may extend the number of cycles during which it communicates with one or more external devices. A device designated as next in line as bus master may be pre-empted under a certain condition.

Abstract: The invention relates to an arrangement for voice transmission, having a voice coder for coding a digital voice signal, which is split into time frames, with the aid of a set of coding parameters which are allocated to the individual time frames. Such arrangements are intended to be used, for example, for the transmission of digital voice signals in the future pan-European digital mobile-radio network. In the case of such a mobile-radio apparatus being installed in a vehicle, it is desirable to provide a voice controller for operation of the apparatus, which voice controller allows the driver to operate the apparatus without him/her having to take one or both hands off the steering wheel. The implementation of a voice controller for a mobile-radio apparatus is, however, very costly, since it is necessary to carry out an analysis of the voice signal spoken by the user. In order to reduce the cost which is necessary for voice identification, it is therefore proposed to provide an evaluation circuit for maintaining at least a part of the set of coding parameters and for converting the coding parameters into identification parameters which are suitable for voice identification. <IMAGE>

Abstract: In a liquid crystal display device (5,5a,5b,5c,5d) having pixels arranged in a matrix form, light is allowed to pass or blocked depending upon whether or not a voltage is applied to electrodes (2,2a,3) each corresponding to the pixels, and the display (5,5a,5b,5c,5d) operation is conducted by controlling the transmission/nontransmission of light. When a conductor (63,70) or switching element (61) connected to an electrode (2a) is broken, it is not possible to apply such a voltage to the respective electrode (2,2a,3). Such a pixel (7a) is always at the light transmission display state, with the result that the pixel (7a) becomes a bright spot, thereby degrading the display (5,5a,5b,5c,5d)quality. Therefore, a blocking piece (6,6A,6a,6b,6c,46a,46b,46c,46d,46e) for blocking light is disposed over the pixel (7a) which becomes a bright spot. This prevents the bright spot from appearing, thereby improving the display quality.

Title: Optical readers
Inventor: DVORKIS PAUL
IPC: G06F3/033
Filed: 1993-06-02
Abstract: To read optically encoded information over a wide range of densities, the present invention provides a spacer system on the tip of an optical reader. The optical reader may be a contact wand type device, for example including a fixed laser emitter. Alternatively, the optical reader may be a moving spot scanner. In either case, the emitter element of the optical reader produces a diverging beam of light. During a reading operation, the spacer contacts the object surface on which optically encoded indicia is formed. The spacer selectively defines at least two different distances between the light emitter, or the focal point of the emitted beam of light, and the object surface. Because of the beam divergence, the diameter of the beam at its point of impact on the object surface will be different for each of the two different distances. The different beam diameters provide the optical reader with different effective sensing spots for reading different density symbols. The present invention also incorporates an optical reader, typically a moving spot laser scanner, into a number of different types of computer data input devices, such as the stylus of a digitizer table and a computer "mouse." In one such integrated terminal embodiment, the optical reader is combined with a touch sensitive display and data input device.
