Patent EP-0371261-A2 (EP)
Inventor: HELM WOLFGANG DIPL-ING
IPC: G01V3/10
Filed: 1989-10-26
Abstract: The invention relates to a method for inductively generating an electrical measuring signal for detecting an electrically conductive body (21), using at least two inductively coupled coils, driver coil (2) and sensor coil (3), through the driver coil of which a higher- frequency alternating current (iT) flows which induces a voltage (US) dependent on the quantity to be measured in the sensor coil and wherein a reference voltage signal (Uref) proportional to the current in the driver coil is generated and both voltage signals are combined with one another in order to obtain the measuring signal. From the reference voltage signal (Uref) and the voltage signal (US) of the sensor coil, the measuring signal (UA) is obtained in which amount and phase of the reference voltage signal (Uref) are eliminated by mathematical logic circuits and thus its dependence on the current (iT) of the driver coil is cancelled and only the change in the amount (¦US¦) and the phase ( PHI ) of the voltage signal (US) of the sensor coil remain as parameters of the measuring signal (UA) which is proportional to the complex power (PT) in the magnetic field of the driver coil, wherein the complex power (PS) within the sensor circuit is kept constant and preferably virtually negligibly small and the voltage signal (US) of the sensor coil (3) has a maximum sensitivity to the object being measured (21, 36, 44), in contrast to the reference voltage signal (Uref), which has a minimum sensitivity to the object being measured. <IMAGE>

Abstract: The present invention provides a transmission line encoding/decoding system wherein encoding is effected in such a manner that an overhead bit which indicates whether or not a slot, all the bits of which are "0" bits (herein­after referred to as an all-"0" slot), is present among a plurality of slots constituting in combination one block and is set in a predetermined slot in the block, and if there are all-"0" slots, a slot information bit which indicates the slot position of at least one all-"0" slot is set and at least one all-"0" slot the position of which is indicated by the slot information bit is deleted, and wherein decoding is effected in such a manner that whether or not an all-"0" slot was present in one block before the encoding process is judged on the basis of an overhead bit set at a predeter­mined position in the block of the received data, and if it is judged that there was an all-"0" slot, the slot informa­tion bit indicating the slot position of the all-"0" slot that has been set in the received block is removed and an all-"0" slot is reconstructed at the position indicated by the slot information bit.

Abstract: A clip-on device for detecting whether or not an optical fibre F is carrying a light signal subjects a first portion of an optical fibre to microbending and detects any light escaping from the fibre as a result. The device comprises an anvil 2 having an undulating surface and a pulsed pressure pad 1, driven by a motor 10, for urging an optical fibre F against the undulating surface of the anvil so that a portion of the fibre is subjected to microbending of a gradually increasing extent. A second portion of the fibre is subjected to macrobending by a light guide 8 or 9, which macrobending is insufficient, by itself, to cause a substantial amount of light to escape from the fibre, but serves to concentrate the light caused to leak from the fibre by microbending of the first portion of the fibre. A control unit 13, operatively coupled to the photodetectors 6 and 7 associated with the light guides 8 and 9 and to the pressure pad 1 gives an output indication on receipt of a signal from the photodetector 6 or 7 that escaping light has been detected and, on receipt of such signal, stops the motor 10 so that the pressure pad 1 is stopped from further increasing the extent of microbending of the portion of the fibre.

Abstract: The symmetry apparatus which allows not only to control the timings of all EFM data signals, but also to control the timing of only a particular EMF data signal. A detector detects a particular EMF data signal having a particular channel bit rate from input EMF data signals. Using a clock delayed by a time period required for the detection operation of the detector and a clock delayed from the particular data by a predetermined time period, only the particular data is delayed by the predetermined time period. It is therefore possible to control the timing of only the particular EMF data signal differently from the other EMF data signals.
