Patent EP-0383587-A1 (EP)
Inventor: MALVERN ALAN C O BRITISH AEROS
IPC: G01C19/72
Filed: 1990-02-15
Abstract: To overcome Kerr effect induced gyro bias in a ring resonator optical gyro, the intensities of the beams travelling in opposite directions around the ring have to be very accurately matched. To achieve this a ring resonator gyro includes a first optical coupler (6), the coupling ratio of which is variable and which divides light from a laser (1) into a first and a second component of generally equal intensity, a second optical coupler (8) which transmits a predetermined proportion of the first component to one input of the ring resonator (15) for transmission around the ring resonator (15) in one sense, and a third optical coupler (9), the coupling ratio of which is variable to couple a variable proportion of the second component to the other input of the ring resonator (15) for transmission around the ring resonator (15) in the opposite sense. The gyro also includes a detector (16) for sensing the intensity of light scattered from the optical ring resonator (15), first varying means periodically varying the coupling ratio of the first coupler (6), sensing means responsive to the output of the detector (16) as the first varying means varies the coupling ratio of the first coupler (6) to sense the difference in intensity in the first and second components travelling around the ring (15), and second varying means to vary the coupling ratio of the third optical coupler (9) and thus the intensity of the second component during alternate periods so that the time averaged intensity of both the first and second components are equal.

Abstract: An asymmetric Fabry-Perot modulator comprises a multiple quantum well (MQW) p-i-n diode (8,10,12) defined by a front surface of reflectivity 0.3 and a back surface of reflectivity 0.95. The cavity length L is such that resonance occurs close to the long wavelength side of the unbiased MQW absorption edge so that application of a bias signal to the MQW (12) causes the reflectivity of the cavity to become close to zero. This arrangement provides a high contrast modulator less sensitive to temperature variations and deviations from ideal reflectivities of the front and back surfaces than high-finesse Fabry-Perot modulators.

Abstract: A curtain wall structure has infill panels (4) supported on a main frame structure through a series of support plates (28). At the periphery of each cell, sealing gaskets (12,14) engage the inner and outer faces of the infill panel. Sealing pressure is applied by auxiliary frame members (6) on which the external sealing gaskets (14) are mounted. The horizontal auxiliary members (6) at the transoms and sills are each provided with a channel (52) to collect any water that may have penetrated the outer seals (14,44). Drillings (54,58) in the auxiliary members and the outer seals allow the collected water to drain away from the wall. The penetration of water to the interior of the building clad by the wall is thus prevented, even though the external sealing means may have become less efficient with the passage of time.

Title: Immobilized oligonucleotide probes and uses therefor.
Inventor: COLLINS MARK L
IPC: C12Q1/6813
Filed: 1990-03-06
Abstract: The invention is a method of detecting nucleic acids in a sample using oligonucleotide probes which are noncovalently bound to solid supports for rapid, sensitive, hybridization assays. The method involves coating the support surface with a polynucleotide and then hybridizing a specific capture probe for each analyte to the polynucleotide by way of a short tail of the complementary polynucleotide. The immobilized probes are used to capture nucleic acid targets out of complex specimens for nonisotopic detection without the need for prior cell culture or purification of the target nucleic acids. A panel of tests can be run on each specimen simultaneously, a format that conserves precious samples. The assay can be readily automated, and can be conveniently run in a manual fashion on large numbers of samples in two to three hours.
