IPC: D03D15/00
Filed: 1995-02-01
Abstract: A woven structure is described in which optical fibers (12A,12B) are positioned and held in the structure in a manner to maximize their optical efficiency. The structure consists of non-optical fibers (10A,10B;11A,11B) extending in both the warp and woof direction, the optical fibers (12A,12B) are positioned in channels between supporting fibers in the warp direction. Selected ones of the non-optical fibers in the warp direction may be electrical conductors. The structure is manufactured using conventional weaving equipment by positioning both the optical fibers and the non-optical warp fibers, and then weaving the woof fibers into place without causing micro-bends or discontinuities in the optical fibers. The structure is woven with the optical fibers positioned in zero warp. The woven grid-like mat can be coated with a protective material that either enables it to form a flexible sheet or a rigid, hard, grid-like mat which has aligned zero warp optical fibers embedded therein. The structure shown can be used to provide sensing, imaging or communications. It can be utilized for optical backplanes for opto-electronic systems or a housing for opto-electronic components. Several types of interconnects or connectors can be fabricated according to the present invention capable of interfacing with the woven structure in an array-based, optical or opto-electronic, active or passive interconnect/connector scenario. The invention may also be used in highly parallel, high performance computer systems and sensing systems.

Abstract: Novel methods of obtaining autologous monoclonal antibodies (AMABs) to self-antigens or homologs thereof are disclosed. The method involves genetically engineering a host animal so that it does not biosynthesize at least one epitope of the self-antigen and utilizes the lack of self-tolerance of the host to the epitope to produce antibodies specific to the antigen. The invention also encompasses the AMABs produced by the methods. The invention further encompasses methods of isolating cells by using such AMABs that have specificity for a cell surface antigen.

Abstract: A method is specified for pitch recognition, in particular for musical instruments which are excited by plucking or striking, in the case of which method the interval between zero crossings of a signal waveform of an audio signal is used as a measure for the period length of the audio signal. 
     Reliable pitch recognition is intended to be possible in a simple manner using such a method. The method is intended to be capable of being implemented with a low level of computation power. 
     To this end, the magnitude of the gradient of the signal waveform is in each case determined in the region of its zero crossings, and the magnitude of the gradient is used as an assessment criterion for the selection of the zero crossings to be evaluated.

Abstract: The device generates an identification signal when a metallic conductive part appears in a non-conductive conveyor stream or flow. In the flow path, an ac generator produces an electromagnetic alternating field, via a transmission coil system, in a section of the conveyor path to be monitored. When a part passes through this field, its amplitude and phase change. These changes are detected by a reception coil and a following analysis circuit in the form of a phase change signal and an amplitude change signal. These signals are used to provide a material specific identification signal. A stage is provided for vectorial addition of the two change signals. A phase comparator receives the vectorial summed signals and one of the change signals. The output signal of the comparator corresponds to the phase angle between the vectorial summed signal and one of the two change signals. An evaluation stage for the phase angle signal is connected to the phase comparator and provides a material specific evaluated control signal. A controllable output stage is connected to the vectorial addition stage. This receives the control signal as a regulation signal. Its output signal serves as a material specific identification signal for a part found in the conveyor flow which is to be identified.

Abstract: A processing unit notifies a drive unit of a designated number N (= 1, 2,....) The drive unit supplies a drive signal of a frequency f 0  to a target measurement device, and supplies a modulation signal of a frequency N·f 0  + Δf to a light source. In this state, an intensity-modulated light beam is emitted from a light source, incident on an E-O probe through an optical system including a PBS and a wave plate, influenced by a periodical voltage waveform generated at a target measurement portion at a fundamental period 1/f 0  to modulate the polarized state, and output from the E-O probe. The optical signal whose polarized state is modulated is input to a photodetector after a polarization direction is selected by the PBS, and heterodyne-detected. The processing unit reproduces the waveform of the voltage signal generated at the target measurement portion by Fourier transform on the basis of the obtained calculation of photodetection signal and displays the waveform.

refractory-metal silicide layer while preventing the overgrowth
phenomenon. This method is comprised of the steps (a) to (c).
In the step (a), a first refractory metal film is formed on a

is formed on the first refractory metal film. The second
refractory metal film contains a same refractory metal as the first
refractory metal film and nitrogen. A stress of the second
refractory metal film is controlled to be a specific value or lower.
In the step (c), the first refractory metal film and the second
refractory metal film are heat-treated in an atmosphere excluding
nitrogen, thereby forming a refractory-metal silicide layer at
an interface between the silicon region and the first refractory
metal film due to silicidation reaction of the first refractory
metal film with the silicon region. The value of the stress of

refractory metal film applies substantially no effect to a plastic
deformation of the refractory-metal silicide layer occurring
