Patent EP-0452747-A2 (EP)
Inventor: LUICH THOMAS M
IPC: H03K17/04
Filed: 1991-04-05
Abstract: An output buffer circuit (800) advantageously uses a simple integrated circuit package including two separate ground leads for connection to an externally supplied ground voltage. The relatively large pull down current which passes through the pull down transistor (835) of one or more output buffers are fed through a first ground lead of the lead frame to the external ground (802) and the remaining circuitry is connected to the external ground (802) through the second ground lead of the lead frame. The transients in the pull down current will cause ground bounce which affects the pull down transistor (835) only, and not the remaining components of the output buffer (800). In this manner, base drive to the output pull down transistor (835) is not decreased due to ground bounce, and the high to low transition of the output voltage is not degraded by the presence of ground bounce. In an alternative embodiment, the amount of ground bounce is controlled to provide a desired characteristic of the output transition.

Abstract: The invention relates to a fastener with a rotary bar, which is designed to be secure while travelling and at customs and possesses a hand lever usable as a lifting aid. The locking is effected with respect to a locking bar by longitudinal displacement of the hand lever over a bearing-side pin/elongated-hole guide, it being possible to improve the operation of the lock by an additional locking and unlocking device. The longitudinal displacement is secure and can be barred by means of a securing element and/or the additional locking and unlocking device. Additional sensors or electronic monitoring devices, which indicate an attempt to manipulate the customs seal or an unauthorised opening of the fastener with a rotary bar, can be attached. <IMAGE>

Abstract: A method for analyzing seismic shear wave data, using a layer stripping technique, to predict subsurface stress regimes is disclosed. Polarization directions of shear wave data, from either a vertical seismic profile or from surface reflection data, are analyzed, and time lags between fast and slow split shear wave are determined. Natural polarization directions of and time lags between the split shear waves in an upper layer are determinded above the shallowest depth where data cues suggest polarization changes take place. Source and receiver axes of the data below the depth of polarization changes are rotated by an azimuth angle, to bring the axes into proper alignment. A static time shift is then applied to eliminate the time lag in the upper layer above the depth where polarization changes were indicated.

Abstract: From a stream of events occurring in a communications system and containing switching or operational or dependability-related events - e.g. requests for setting up connections (VA) - events are selected in accordance with a predetermined percentage - e.g. requests for setting up connections (VA) which are rejected due to overloading of the communications system, for example a communication switching system (KA). This is achieved by the fact that when event occurs, a counter is controlled in such a manner that with a count (ZS) of greater than a predetermined number, the currently occurring event (VA) is determined as selected event (VA) and with a count (ZS) less than or equal to a predetermined number, the currently occurring event (VA) is determined as non-selected event (VA). The counter is controlled with the aid of additions and subtractions which place little load on the controllers of the communications system. <IMAGE>

Abstract: Optical disk drive apparatus comprises an optical head for projecting a laser beam onto the recording surface of an optical disk seek control means (90) controllers movement of the beam from a current track on the disk to a target track. Tracking error signal generating means (72) generates a tracking error signal (TES). The TES indicates the deviation of the beam from the centre of a track in the radial direction of the disk. Track number countering means counts, as a function of the TES, the number of tracks crossed by the optical head. The track number counting means comprises a positive peak level comparator (401) for generating a positive peak pulse when the TES is higher than a predetermined positive level; a negative peak level comparator (402) for generating a negative peak pulse when the TES is lower than a predetermined negative level; and a logive circuit (500) for generating an output pulse in response to the positive peak pulse and the negative peak pulse being generated in a predetermined sequence. This advantageously ensures that the number of tracks crossed is precisely counted even if the optical head passes over a defective portion of the disk.

Abstract: The underside of a vehicle is imaged by means of a sensor 1 located behind a lens 2 in a recess 4 in a speed hump or pit over which a vehicle may drive. The sensor images one complete sideways strip of the vehicle at a time, and this is read out as a line into a frame store. Successive lines are read into the the frame store at a rate dependent upon the relative speed of the speed of the vehicle relative to the sensor. The speed of readout of the sensor may be reduced for the outer portions of the line compared to the central region in order to correct for distortion resulting from viewing the size of vehicle at an oblique angle. An undistorted image of the underside of the vehicle may be built up without interrupting vehicle flow.
