Title: Day/night mirror
Inventor: JACOB KEITH D
IPC: B60R1/08
Filed: 1986-05-16
Abstract: A day/night rearview mirror comprises an optical medium which is electrically driven between transmissive and opaque states. The mirror comprises a housing containing a circuit board overlaid by a mirrored surface. The mirrored surface is in turn overlaid by an optical transmission plate containing the optical medium. Electrical conductivity from the circuit board to the transmission plate is provided by helical coiled spring conductors which are supported in sleeves integrally formed with a retaining frame for the mirrored reflecting surface of the mirror. The circuit board contains a circuit for controlling the optical transmission plate and controls which are accessible to the user to adjust operational characteristics of the mirror assembly, and a pair of sensors which sense ambient lighting and incident light from the field of view, respectively.The sensors are coupled in via electronic input circuits (104, 106) to a logic gate (108), which controls the optical transmission plate. The transmission plate is forced to an opaque condition only when both a night-time ambient condition is sensed and there are also bright lights from the field of view.The circuits impose certain timing requirements on changes in sensed conditions so that the mirror does not change state in response to momentary departures from generally prevailing conditions. <IMAGE>

Patent GB-2186076-A (GB)
Title: Chemical monitor
Inventor: HOLMES-SIEDLE ANDREW
IPC: G01N21/35
Filed: 1987-01-30
Abstract: A chemical monitor has a solid- state source 12 of radiation (e.g. an LED) and a solid-state detector 16 for the radiation within a sample chamber 14. Gas is drawn through the sample chamber 14 and the source 12 activated by circuitry 20. The wavelength of the radiation is selected to correspond to an absorption wavelength of a component of the gas (e.g. methane) and the variation in radiation detected by the detector 16, measured by circuitry 22, then gives a measure of the amount of the component of the gas present. The sample chamber may be a straight or convoluted hollow tube, or a rectangular or square box with an elongate optical path then being achieved by mirrors within the box. The use of a solid-state source enables the source to be immersed in the gas, even if the gas is explosive or inflammable, thus eliminating the distortion or loss which occurs in systems where the source and gas must be separated. <IMAGE>

Title: "Optical repeater supervisory system"
Inventor: YAMAMOTO SHU
IPC: H04B10/07
Filed: 1989-04-06
Abstract: An in-service optical repeater supervising system uses mBIP code (in which date is assembled into blocks of M data bits plus 1 parity bit), and a carrier signal S5 of the supervising signal for supervising an optical repeater Y is generated from the frame frequency by causing a parity bit Pb to be repeatedly inverted between an even parity bit Pb2 and an odd parity bit Pb1 in successive frames. With this supervising system, even when the error ratio of the line code is degraded, the optical repeater Y can respond to a supervisory command signal, since the carrier frequency level of the supervising signal does not decrease. <IMAGE>
