Patent EP-0454999-A2 (EP)
Inventor: LIU KAREN
IPC: G02B26/00
Filed: 1991-03-28
Abstract: This invention describes a double-pass optical filter having a pair of reflective surfaces (14, 14') with a pair of optical media (7, 8) of different indices of refraction inserted between the surfaces (14, 14'). Light is then passed through the surfaces and through each of the optical media (7, 8) to obtain selected frequencies. This invention also includes a means (11) for varying the distance between the reflective surfaces (14, 14') so as to tune the filter over a continuous range of frequencies. This continuous simultaneous tuning of two resonant cavities (7', 8') can be achieved by merely displacing one reflective surface relative to another.

Abstract: This invention relates to semiconductor integrated circuits which find utility in analogue systems. An integrated circuit of the invention comprises an array (A) of configurable analogue cells (CL) each of which is capable of interconnection with other cells in the array by means of an interconnection network (HB, VB). Each of the cells can be selectively and individually selected by means of select signals (SS) and (DD) emanating from shift registers (DSRH, PSRV). When selected the cell (CL) may be configured with configuration data (DD, AD) which both sets the cell to take up a particular electrical configuration by means of digital data (DD) and sets various programmable resistors and capacitors (P/res, P/cap) in the cells to particular values by means of analogue signals (AD). The configuration data is held in a random access memory RAM. Some of this data is converted to analogue form (AD) by means of a ditigal-to-analogue converter (DAC). The circuit is controlled by a central control (CC) and is capable of being configured to implement particular analogue functional applications from a plurality of possible analogue functional applications. Provision in the circuitry is made to automatically compensate for manufacturing component tolerances.

Abstract: A receiver (13) for a direct sequence spread-spectrum communication system of the type in which a transmitter (12) mixes a clocked pseudo-random sequence with a modulated carrier for spreading the carrier energy across a wide band of frequencies. The receiver comprises a resident clock-driven pseudo-random code generator (23) for locally generating an essentially identical, spectrum despreading code sequence; means (25) for clocking the resident code generator at a nominal frequency which is offset in a predetermined sense from the clock frequency of the transmitted code sequence such that the phase of the locally generated code sequence tends to slide in one direction with respect to the phase of the transmitted code sequence; detection means (32) for determining whether the the locally generated and the transmitted code sequence are phase aligned or misaligned and for sensing their actual, incipient and/or predicted departures from a phase aligned state; and phase control means (31) for adjusting the clock frequency for the resident code generator whenever such a departure is sensed, thereby shifting the phase of the locally generated code sequence in the opposite direction with respect to the transmitted code sequence by an amount which tends to restore the two code sequences to a phase aligned state. In other words, in keeping with this invention, the receiver has a sliding correlator for phase correlating its locally generated code sequence with the transmitted code sequence at the outset of each incoming transmission, together with a phase controller for regulating the rate at which its resident code generator is clocked once such phase correlation has been achieved, whereby the resident code generator of the phase correlated receiver is clocked at substantially the same average frequency as the transmitted code sequence for the balance of the transmission.

Abstract: An auxiliary quasi-resonant dc link (AQRDCL) converter is employed to achieve soft-switching in an inverter coupled to a dc supply via a resonant dc link circuit. The resonant dc link circuit generates a quasi-resonant voltage to the inverter via a resonant bus. The dc link circuit includes upper and lower capacitors coupled in series between the positive and negative rails of the dc supply, respectively, with the voltage across the lower capacitor being controlled to be greater than the voltage across the upper capacitor. In this way, the need for a switch shorting the resonant bus to ground during a resonant cycle is avoided. An auxiliary switching device assists resonant operation of the resonant bus to zero voltage in order to provide a zero-voltage switching opportunity for the inverter switching devices as the inverter changes state. The AQRDCL then quickly resonates back up to the positive rail voltage as a clamping circuit clamps the resonant bus voltage thereto either with or without the assistance of a second auxiliary switching device, as desired. The auxiliary switching device(es) operates under zero-current switching conditions and at a rate that is below the resonant frequency of the resonant dc link circuit. In addition to high efficiency, the AQRDCL converter has low current and voltage stresses and uses a minimal number of circuit components. The AQRDCL may be used to achieve soft-switching in a variety of inverter topologies, including a switched reluctance machine inverter.

Abstract: Sample liquid analysis apparatus (20) and method are provided and comprise the formation and supply to a conduit (134) of a stream of successive sample liquid test packages (TP1, TP2), and the repeated bidirectional displacement of the sample liquids test package stream in the conduit through one, or a plurality of spaced, sample liquid analysis apparatus (138, 244) which are operatively associated with the sample liquid conduit to provide for repeated, time-spaced analyses in turn of the sample liquids in each of the sample liquid test packages. Each of the sample liquid test packages (TP1) comprises a first segment of a sample liquid (S1) and a first reagent liquid (R1), and a second segment of a second reagent liquid (R2) spaced from the first segment by a different fluid (A3) in the test package. The conduit (134) includes a portion (140) which is operable to combine the respective first and second segments of each of the sample liquid test packages upon the flow of the same therethrough to commence the sample and reagent liquids reaction for sample liquid analysis; and the, or at least one of the, sample liquid analysis apparatus (138) is disposed upstream in the conduit of this conduit portion to enable independent analyses of the respective first and second segments of the sample liquid test packages in turn prior to the combination thereof. Precisely operable, positive displacement pumping (100, 280) operatively associated with the conduit inlet or with both the conduit inlet and outlet and, in that event, precisely coupled to provide for differential pumping, is utilized for the formation and supply of the sample liquid test packages in turn to the conduit to form the sample liquids test package stream therein, and for the repeated bidirectional displacement of that stream in the conduit. An isolation liquid (IL) which is immiscible with the sample and reagent liquids, and which preferentially wets the walls of the conduit to the substantial exclusion of those liquids, is introduced to the conduit to minimize the adherence of the sample liquids thereto, thereby minimizing sample liquid carryover, and maximizing sample liquids analyses accuracy.

Abstract: For image analysis apparatus an integrated circuit can perform specific pattern analysis with an image projected on the photodetector array processors which include current mirrors for receiving an image and processing in parallel the information in a received light signal. The photodetector array organizes and distributes light to provide a filter for providing a discrimination analysis path for a received light signal to process the received image for spectral analysis, for steering the angular direction of incoming light from an image, for color or grey scale analysis. A shutter mechanism enables differing kinds of image analysis. The integrated circuit has photodetectors replicated on the surface and normally a lens of polyimide deposited on the surface. When a lens shutter is employed it is adapted to be moved in a plane in an analog fashion to change the lateral position and thus change the dominant angle viewed by the photodetector by piezoelectric drivers which move the shutter just a very small amount.
