Abstract: A frequency modulation (FM) stereo broadcast receiver detects the onset of multipath interference based on phase changes in the received stereo pilot signal. In a preferred embodiment, the phase of the received pilot signal is compared to the phase of a regenerated pilot from a phase-locked loop in a stereo decoder circuit (22). The severity of a multipath event is determined by the phase shift detected at the onset of the multipath event.

Title: Electric field measuring apparatus
Inventor: TAKAHASHI HIRONORI C O HAMAMAT
IPC: G01R31/308
Filed: 1993-07-23
Abstract: This invention relates to an electric field measuring apparatus for causing an optical probe head having an electrooptic member with an electrooptic material to oppose a sample such as a semiconductor integrated circuit device and for optically measuring a voltage of an opposite portion of the sample. The electrooptic material consists of an LiTaO₃ electrooptic crystal or the like, the polarization characteristics of which change depending on the electric-field strength of the sample. More specifically, the electrooptic member is supported on a guide mechanism to be reciprocally movable within a predetermined stroke range in a direction of the sample. The guide mechanism is reciprocated in the direction of the sample to control the distance between the electrooptic material and the sample. In measurement, light is incident on the electrooptic material whose polarization characteristics have changed depending on the electric-field strength, and the light intensity of a predetermined polarized component of the light reflected by the electrooptic material is detected, thereby measuring the electric-field strength and voltage of the sample. Even if the electrooptic member is brought into contact with the sample, the sample is not damaged due to the stroke set in the guide mechanism. The simple structure of the guide mechanism realizes improvement of operability. The electrooptic member can come very close to the sample to increase the measurement sensitivity.

IPC: G01S13/78
Filed: 1993-03-22
Abstract: The invention relates to a method for detecting mixtures of pulses received by an SSR. The SSR includes a monopulse antenna making it impossible to obtain a power pulse signal LOG  SIGMA I(t) and a distance measurement pulse signal  DELTA / SIGMA (t), which are synchronous, from the pulses received. The method according to the invention consists in detecting both the wave variations superposed with the power signal and the wave variations superposed with the distance measurement signal, the presence of at least two mixed pulses (5, 6) being detected by the presence of wave variations on at least one of the two signals. Application: receiver circuits for SSR. <IMAGE>

Abstract: An optical pressure transducer includes a body for supporting therein both an input optical fiber and an output optical fiber. A light source generates input light to the input optical fiber. A force responsive diaphragm is secured to the body and deflects in response to sensed pressure. A fixed reflector and a moveable reflector, which is attached to and moves with the diaphragm, are disposed in the optical path between the input and output optical fibers and reflect at least a portion of the input light from the input optical fiber to the output optical fiber. The amount of light reflected depends upon the deflection of the diaphragm. A system for monitoring and controlling the light source, including an optical detector in a feedback arrangement, is provided such that the amount of light generated by the light source remains constant and maximized.

Abstract: Un ensemble à structure (12) permet de mesurer des forces et des moments relatifs à trois axes orthogonaux (76, 78, 64) dont un longitudinal (64). Ledit ensemble ne transmet que de très faibles interférences lorsque l'un des axes est affecté par des charges s'exerçant au tour ou le long d'un autre axe. En pratique, la structure de support (44) tolère des moments appliqués autour de l'axe longitudinal (64) et elle est rigide face aux forces appliquées le long des axes orthogonaux (76, 78, 64) et aux moments appliqués autour des axes orthogonaux non longitudinaux (76, 78). Un capteur de couple (46), chargé de mesurer des moments sur un axe longitudinal (64), est placé concentriquement sur ledit axe, soit dans une cavité (60, 62) du support (44) soit autour de ce support. Des diaphragmes de flexion supérieur (48) et inférieur (50) relient les extrémités adjacentes du support (44) et du capteur de couple (46) et transmettent les moments appliqués à l'axe longitudinal (64) au capteur de couple mais tolèrent les forces et moments axiaux appliqués aux axes orthogonaux non longitudinaux (76, 78).

Title: Ultrasonic distance measuring device.
Inventor: BAUMANN ERWIN
IPC: G01F23/68
Filed: 1993-03-25
Abstract: The sound wave of an ultrasonic trasducer is coupled through a tuned intermediate tubular component (7) into a measuring tube in which it is reflected at the plane reflection surface of a reflector. The intermediate tubular component (7) consists of an inlet cone (20), a cylindrical part (21) and an outlet cone (22). The reflector is slaved to the level in the tank. The reflected sound wave is processed in the same ultrasonic transducer in order to determine the distance. This ensures a high degree of precision and resolution over a large distance range, reduced power requirements for the driver module, and simpler circuit design since complex processing of echo signals is unnecessary, resulting in production cost benefits.

Abstract: To manufacture airbags consisting of a contact fabric and/or a filter fabric it is proposed to use hollow fibre synthetic filament yarns having a hollow area fraction of 10-40%, based on the total cross-sectional area of the fibre. The fabric closeness values are > 72% for the contact fabric and 45-68% for the filter fabric. In addition to reducing the production costs, the use of hollow fibres also makes it possible to produce lighter fabrics. These show themselves to advantage in a higher functional reliability of the airbag.
