Title: Electro-optic waveguide device
IPC: G02F1/295
Filed: 1988-10-31
Granted: 1993-07-28
Abstract: PCT No. PCT/GB88/00928 Sec. 371 Date May 22, 1990 Sec. 102(e) Date May 22, 1990 PCT Filed Oct. 31, 1988 PCT Pub. No. WO89/04988 PCT Pub. Date Jun. 1, 1989.An electro-optic waveguide device (10) comprises an assembly of waveguides (30) connected to a common light input region (41) and forming a common far field diffraction pattern (44). The device (10) comprises an n+ GaAs substrate (14) bearing a waveguide lower cladding layer (16) of n+ Ga0.9Al0.1As, which is in turn surmounted by a waveguide core layer (18) of n- GaAs. The layer (18) has grooves (20) defining the waveguides (30), each of which has a respective Schottky contact (32). Each contact (32) is biased negative with respect to the substrate (14), which reverse biases the respective Schottky diode waveguide structure. The waveguide core layer (18) has electro-optic properties, and its refractive index varies with electric field. The phase of light emerging from each waveguide is therefore independently variable by means of its applied bias voltage. The waveguides (30) are arranged to provide output confined very largely to lowest order spatial modes, so that they produce a single far field diffraction pattern (44). Varying the set of bias voltages applied to the waveguides (30) produces output phase variation which changes the position of the diffraction pattern principal maximum (46) to produce beam steering.

Title: A regenerative node for a communications network
IPC: H04J3/06
Filed: 1989-04-06
Granted: 1993-08-04
Abstract: A regenerative node for use with scrambled, time domain multiplexed (TDM) data channels has a delay-lock receiver (6) for locking onto a channel scrambled by its associated scramble sequence or a common scramble sequence; a transmitter (4) slaved to the receiver (6) for providing data to be transmitted by the node which has been scrambled by the another node's scramble sequence or an empty channel signal scrambled by the common scramble sequence in phase synchronism with the TDM channel to which the receiver is locked; and a regenerator (8) for regenerating the received TDM channels or the TDM channels with the transmitted data overwriting the delay-locked channel. A node wishing to set up a call searches and delay-locks to a channel having a channel empty sequence scrambled by the common sequence and once delay-locked to it transmits a signal scrambled by the destination nodes sequence. The other node will subsequently delay-lock to this channel and transmit to the first node in the same TDM channel using the scramble sequence of the first node. The invention finds particular application in ring networks for 2-way video communications.

Abstract: A high voltage regulator circuit for maintaining the ultor voltage applied to a picture tube of a television receiver apparatus provides an auxiliary voltage signal for compensation of variations in the ultor voltage caused by variations in the beam current. An improved phase control circuit controls the phase position of the pulses of the auxiliary voltage signal so that they lag with only the leading parts thereof overlapping the retrace voltage signal pulses, in order to prevent the introduction of fluctuations in the ultor voltage due to secondary ringing. The phase control circuit includes a sawtooth waveform generator which generates a sawtooth signal corresponding to the retrace pulses, a reference voltage generator which generates a reference voltage corresponding to the ultor voltage, a comparator for comparing the sawtooth signal to the reference voltage, and a one-shot multivibrator circuit responsive to the comparator output for generating a pulse signal for the auxiliary pulses lagging in phase to the retrace pulses.

Abstract: Improved chromatographic strip binding assay devices are provided for determining the presence or amount of an analyte present in a patient sample. Assay label reagents interact with capture reagents immobilized in a testing region on the strip substrate to generate a visually detectable image indicative of the test result. The test result images include a minus sign (-) to indicate a negative test result for analyte which image is generated if the suspect analyte is absent in the patient sample and a plus sign (+) to indicate a positive test result for analyte which image is generated if the suspect analyte is present or is present at a pre-determined concentration in the patient sample. The immobilized capture reagents responsible for the location and configuration of the test result images are applied to the strip at an angled orientation with respect to the fluid flow direction of the strip to ensure that sharp substantially complete test result images are formed during performance of the assay. The devices provide substantially self-performing assays having inherently clear test results which are not subject to misinterpretation by the skilled or untrained user.

Abstract: Heating apparatuses for packaging materials operating with hot air are often employed for heating thermoplastic packaging materials in connection with heat-sealing, forming or the like. The heating apparatuses are energy-intensive and suffer from a relatively low degree of efficiency, which primarily relates to a considerable waste flow of heated air. A heating apparatus in which these drawbacks have been obviated displays a suction box provided with apertures, the box being located adjacent a nozzle for the hot air and connected, by the intermediary of a recirculation duct, to the intake side of means generating an air current.

Abstract: A heating element (20) having an associated air-cored coil (7) is sited beneath a glass ceramic plate (21) as a sensor for determining the presence or absence of a cooking utensil. The air-cored coil (7), which forms part of an oscillatory circuit of an oscillator, is measured in fixed time pulses of ( DELTA t) in relation to the applied frequency per unit time. If a cooking utensil is placed on the glass ceramic plate (21) the frequency per unit time increases and if this change is detected over more than one measurement cycle, the heating element (20) is switched on. Subsequently, the frequency measured last is always used as reference frequency for the subsequent measurement. The frequency difference per unit time changes by a specified amount only when the cooking utensil is removed from the glass ceramic plate (21) and a further switching pulse is applied to the on/off switching relay (6). <IMAGE>
