Title: Viability test device
IPC: G01N33/52
Filed: 1986-02-17
Abstract: A viability test device wherein the viability of a test composition for the determination of an analyte of interest can be determined by simply wetting the device with ordinary water. The viability device can be prepared in three formats: a control or calibrator device, an internal control device and a self indicating device. Unreacted analyte, or an analog thereof, can be incorporated in a limited defined portion of a dried carrier matrix incorporated with a test composition to provide an internal control test device. When wetted with water, a positive optical response, usually color, indicates the test composition can provide a viable test for the analyte. The internal control test device is particularly advantageously used by diabetics in their own homes where a negative test response could be due to the desired control of the user's condition or due to deterioration of a test composition because of unfavourable storage conditions.

Abstract: In order to increase the information carrying capacity of 
an optical fiber communication system, at the transmitting 
side of the system a reference optical beam and a 
plurality of closely spaced optical carriers having 
frequencies which are coherently related to the reference 
frequency of the reference optical beam are generated and 
the plurality of closely spaced optical carriers are 
combined to provide a multiplexed optical output beam. At 
the receiving side of the system a frequency tracking 
optical beam tracks the reference optical beam and the

multiplexed optical output beam are optically heterodyne 
detected by the tracking optical beam to convert the 
plurality of closely spaced optical carriers into a 
microwave spectrum, so that the individual carrier 
frequencies present in the microwave spectrum which 
correspond to the frequencies of the plurality of closely 
spaced optical carriers may be electronically heterodyne 
detected and separated from the microwave spectrum.

Patent EP-0277623-A3 (EP)
IPC: G01N27/04
Filed: 1988-02-01
Abstract: An element (30) for detecting internal faults in an insulating 
gas charged electrical apparatus comprises a substrate (31) 
disposed in the electrical apparatus charged with an insulating 
gas, a pair of electrodes (32) disposed on the substrate (31), 
and a thin metal film (33) covering the pair of electrodes 
(32) and the exposed surface of the substrate (31). This 
film (33) is capable of producing fluorides with low 
conductivity upon reacting with a decomposed gas produced 
by internal faults of the electrical apparatus. Since the 
thin metal film (33) exhibits high response characteristics 
readily in reaction with even a trace amount of a decomposed 
gas, it is possible to detect at an early time faults 
occuring in the electrical apparatus, such as a partial 
discharge or local heating. In addition, a device for detecting 
internal faults in an insulating gas charged electrical 
apparatus using the internal fault detection element (30) 
utilizes an optical signal for transmitting signals. 
Accordingly, the device is free from electromagnetically 
induced interference and is capable of remote monitoring 
by making use of the low level of loss in signal transmission.
