Patent GB-2239520-A (GB)
Title: Optically-sensed vibrating element detector
Inventor: WILLSON JOLYON PETER
IPC: G01B11/00
Filed: 1990-12-18
Abstract: In an optically-excited micromachined silicon pressure sensor comprising a resonantly vibrating beam mounted on a diaphragm, vibration of the beam is sensed optically via the same optical fibre through which the optical excitation signal is applied to the sensor. The end of the fibre and the beam are arranged to define a cavity or gap whose width varies with vibration of the beam and which behaves as a Fabry-Perot cavity: thus light from the fibre is directed onto the beam and then reflected back to the fibre, the reflected light being modulated at the frequency of vibration of the beam. In order to overcome the difficulty of setting the gap or cavity width at an optimum value for light of a given wavelength, light of two different wavelengths is used to sense the vibrations, the wavelengths being selected such that the phase difference produced by the gap for one wavelength differs from that for the other wavelength by roughly 90 DEG .

Patent GB-2246230-A (GB)
Title: Shape sorting
Inventor: COOK NIGEL ROGER
IPC: B07C5/10
Filed: 1991-06-25
Abstract: In order to provide an accurate sort into many different classes, objects are passed through a viewing zone and viewed at the same instant by a number of viewers. Signals from the viewers are processed to provide signals representative of the maximum, minimum and mean of the blockiness and symmetry of the object, and the maximum and mean of the convex hull deviance of the object. The signals, together with an edge-breakthrough count are subjected to a linear transformation to provide a normalised shape parameter which is then assigned a value of 0 to 15, for each class being sorted, on the basis of the expected occurrence of the value of the parameter in that class. Each pair of secondary shape parameters so determined is used to derive a decision value from the table specific for that pair of secondary shape parameters. The shape class of the object is ascertained on the basis of a majority vote for all the shape decision values. The tables are "learnt" by the machine by feeding a statistically significant number of samples representative of a number of shape classes through the machine.

Title: A water-activated survival lamp unit and an improved water sensing switch therefor
Inventor: BRAIN JOHN ERRINGTON
IPC: B63C9/20
Filed: 1991-11-01
Abstract: A water-activated survival lamp unit (20) for mounting to a flotation device in proximity to the water line comprises a hermetically sealed light transmissive housing in-which are mounted a light source and a battery in an electrical circuit together. A water-sensitive actuator is provided, including a pair of electric terminals extending outside the housing in a spaced apart relationship. The actuator is responsive to a momentary electrical path established between the terminals through a coherent body of water to close the electrical circuit between the battery and the light source for a predetermined time period largely exceeding the duration of the electrical path, thus causing timed actuation of the light source. Periodic water splashing of the electric terminals allows the electric path to reestablish at intervals, each time resetting the actuator which closes the electrical circuit for an additional time period. <IMAGE>
