Abstract: PCT No. PCT/EP90/01150 Sec. 371 Date Feb. 21, 1992 Sec. 102(e) Date Feb. 21, 1992 PCT Filed Jul. 13, 1990 PCT Pub. No. WO91/01535 PCT Pub. Date Feb. 7, 1991.A medical apparatus to be worn in the mouth comprises a battery-fed measuring unit (15) including a clock generator (18) and a counter (20) for counting the pulses of the clock generator. Accuracy of the time measurement decisively depends on the precision of the oscillating frequency of the clock generator. In the invention, there is used a clock generator (18) wherein frequency precision is low. When the counted value of the counter (20) is read into an external evaluating unit, the measuring unit supplies a reference time required by the clock generator (18) for generating a number of pulses. The evaluating unit calculates the time corresponding to the counted value under consideration of the length of the reference time. Thus, the evaluating unit measures the cycle length of the pulses of the clock generator, and this cycle length is multiplied by the number of the counted clock pulses. In this manner, time measurement is performed in a precise manner without requiring a highly precise clock generator.

Abstract: The present invention relates to a multiplexing circuit for clock signals, the output signal from this circuit being the clock signal identified by a selection signal. The multiplexing circuit for clock signals is controlled by one selection signal at least. An invariable switching level being one of the two levels of these clock signals, the circuit comprises, for each clock signal, a timing module producing a delayed clock signal taking the value of this clock signal for a first state of the selection signal in the absence of a busy signal as soon as a switching level of this clock signal appears and interrupting this delayed clock signal when the selection signal is in a second state as soon as a switching level of the clock signal appears, control means producing the busy signal as soon as a timing module produces a delayed clock signal, and means for producing, as output signal, the delayed clock signal output by the selected timing module. <IMAGE>

Abstract: A procedure for automatically adapting the braking force of a yarn brake located in the hollow spindle axle of a two-for-one twisting spindle to changed spindle speeds is characterised in that the vacuum generated by the suction-air stream of the rotating spindle and therefore dependent on the spindle speed acts on a braking surface (6) of the yarn brake in such a way that, with an increasing or decreasing speed of the two-for-one spindle, this braking surface is brought to bear against the brake body (7) with an increasing or decreasing pressure force. A two-for-one twisting spindle for carrying out this procedure, having a yarn brake which is located above the yarn storage disc in the region of the hollow spindle axle and which has at least one braking surface accommodated in a brake housing and a brake body bearing against the braking surface, is characterised in that the braking surface (6) forms part of a piston (14) which is displaceable in the axial direction in the brake housing (13) and which limits the top side of a vacuum chamber adjacent to the central orifice of the yarn guide channel (2.2) of the yarn storage disc (2.1) <IMAGE>

Abstract: A technique for near-field tomographic imaging using a multiple-receiver correlating interferometer. A target object (T) or scene to be imaged is located in a near-field or Fresnel region of a receiver system. The target object radiates or reflects a signal that is sensed by a plurality of antennas (P,Q). The received signals are correlated using conventional correlation algorithms. An image pixel for a focal point (F) is then computed by correcting a differential time delay between a signal emitted at the focal point and received at first and second antennas. The system is focused on the target object by correcting a phase term of the correlation algorithms. The phase term is corrected by multiplying the correlation algorithms by a phase factor. A peak correlated value is developed when the focal point is at the target object location (T). A series of snapshots is generated from data produced by the focussing process, as the focal point is moved through the scene. The snapshots are successively superimposed, using tomographic techniques, to form a high resolution image map. The system achieves extremely high resolutions, rivalling those of synthetic aperture radar.
