Patent GB-2135196-A (GB)
Title: A probe, particularly a clinical probe for intracorporeal use
Inventor: MCLEOD CHRISTOPHER NEIL
IPC: A61B5/042
Filed: 1984-01-31
Abstract: A method of constructing a monitoring probe is disclosed which is formed of an elongate plastic probe body having electrical leads passing through the probe body and connected to appropriately positioned monitoring electrodes on the surface of the probe body. The monitoring electrodes are formed by applying a solution of plastics material containing dispersed particles of an electrically conducting material together with a volatile solvent on the probe body and over the leads extending initially exposed through the probe body. Upon evaporation of the volatile solvent the plastics material with the electrically conducting material adheres to the surface of the probe body to form smooth monitoring electrodes. With this arrangement the possibility of mechanical injury to a patient due to the smoothness of the electrode finish, is much reduced compared to that possible using prior art oesophageal probes which are possessed of jagged edges and the like which cut the mucosa in the oesophagus, and are difficult to clean and sterilize. <IMAGE>

Patent GB-2168575-A (GB)
Title: Improved data channel
Inventor: REID DAVID
IPC: G11B5/012
Filed: 1984-12-18
Abstract: A data channel for decoding data representative analogue signals is shown in exemplary use in a disc data store. The data channel comprises parallel first (86,88,90,92) and second (96,98,100,102) signal paths. The first signal path (86,88,90,92) comprises a wide band low pass filter (88) and the second signal path (96,98,100,102) comprises a narrow band low pass filter (98). Each of the first and second signal paths produces a logic output signal representative by logical sense of the time rate of change of the incoming analogue signal at the respective bandwidth of the two signal paths. The logic outputs of the two signal paths are provided as input to combining logic (106) whose output is clocked by logic changes in the output of the first signal path to present as output the logical state of the output of the second signal path. The signal on the second signal path is arranged to be in phase advance over the logical output of the first signal path. The narrow band second signal path produces a signal of high inter-symbol interference, but immune from spurious noise pulses. The logical output of the first signal pulse produces a signal repeat with erroneous pulses induced by noise, but where timing relationships are accurate. The combining logic combines the two signals to provide output which is free from erroneous noise pulses whilst retaining the timing accuracy of the first signal path logic output (Fig. 6A).

Title: Electronically commutated motors
Inventor: ERDMAN DAVID MARVIN
IPC: H02P6/18
Filed: 1986-07-15
Abstract: A control system for an electronically commutated DC motor having a plurality (e.g. three) of stator winding stages, enables the application of a DC voltage to the winding stages in sequence to cause rotation of the motor rotor. A neutral conductor voltage of the motor is approximated and compared with the back emf of one of the winding stages to obtain an output representing the angular position of the rotor. The winding stages are commutated in response to this output when a predetermined angular position is reached. The DC voltage applied to the winding stages is pulse width modulated by alternately pulse width modulating first (41) and second (47) drive circuits. The first drive circuit associated with a winding stage which remains on after commutation is pulse width modulated until a predetermined time after commutation and then there is a shift to pulse width modulate the second drive circuit associated with the winding stage which will remain on after the next commutation. A method of operating an electronically commutated motor and a laundering apparatus are also disclosed. <IMAGE>

Title: Thermally compensated reference interferometer and method
Inventor: WILSON KEITH E
IPC: G01C19/72
Filed: 1987-12-23
Abstract: A first birefringent material is positioned to receive an optical signal output from an optical source. A second birefringent material is positioned to receive the signal transmitted through the first birefringent material. The birefringence of the first birefringent material is modulated to produce a modulation in the phase difference between two polarizations propagated between the birefringent materials. A detector forms an electrical signal indicative of the phase shift produced by the first and second birefringent materials between a pair of orthogonal polarizations in the optical signal received by the first birefringent material. This phase shift is opposite to phase shifts caused by changes in the source wavelength. A feedback signal indicative of the phase shift caused by the crystals is fed back to the optical source to stabilize its frequency. The system produces a temperature-independent phase shift between the two polarizations by apparatus of proper selection of the lengths of the crystals in the optical path.
