Title: Measuring proximity of a metal object
Inventor: GILL MICHAEL JOHN
IPC: G01V3/10
Filed: 1987-09-16
Abstract: A device for measuring the proximity of a metal object includes a drive and sense coils 220, 230 which are loosely coupled together. The drive coil is driven by a continuous, alternating square-wave drive signal, controlled by a micro-processor 200. The amplitude of the signal sensed by the sense coil 230 in response to the drive signal is dependent upon the proximity of a metal object. Sensing circuitry 250, 290 is provided for measuring the amplitude of this signal to derive a signal indicative of the proximity of the metal object. In particular, a multiplexor 280 is provided for sampling predetermined parts of the signal, (which exhibits a time-dependent change when a metal object is proximate) during a part of the cycle of the drive signals when the amplitude thereof is constant. By ignoring the initial part of each half cycle of the received signal, effects due to conductive but non-metallic proximate objects may be ignored. A particular application of the device is for sensing the depth of reinforcing iron bars in concrete. A construction of a sensor Fig. 3 (not shown) is also disclosed. <IMAGE>

Patent GB-2220501-A (GB)
Title: Coupling waveguides using transverse cylindrical lenses
Inventor: DRUMMOND ERIC IAN
IPC: G02B6/42
Filed: 1988-07-06
Abstract: An optical system coupling a waveguide such as a laser diode (4) to a waveguide such as an optical fibre (6) must transform the beam ellipticity for efficient coupling.
