摘要:
Deactivation of a magneto-mechanical EAS marker is achieved by demagnetizing (degaussing) the bias element. The deactivator has typically high voltage capacitors in the LC circuit. The invention suggests to reduce the capacitor size in the LC circuit of the deactivator. The deactivator may thus be smaller, less expensive and the charging time of the capacitor may be reduced to approximately 7 ms.

A coil array for an EAS marker deactivation device is formed of three co-planar "pancake" coils (L1, L2, L3) energized by an a.c. drive signal (22) and arranged to provide significant alternating magnetic fields in each of two orthogonal, horizontal directions. The coil geometry and arrangement are selected to provide smooth field distribution to minimize the possibility of harm to video and audio tapes and other magnetic medium products.

A deflection yoke having a capability of correcting a lateral inner pincushion distortion with a magnetic field generated by a deflecting coil itself is provided. The deflection yoke includes a saddle-type vertical deflecting coil 20 including a screen side bend portion 51, a neck side bend portion 53 and a cone portion 52 connecting the screen side bend portion 51 and the neck side bend portion 53 and is installed to a cathode ray tube. When viewing the screen side bend portion 51 of the vertical deflecting coil 20 from a screen side of the cathode ray tube in a direction along the tube axis, a distance between the screen side bend portion and the tube axis is the minimum at a portion 51a close to a diagonal direction of the screen. As a result, the lateral inner pincushion distortion can be corrected with a magnetic field generated by the deflecting coil itself with a simple configuration, without adding any component for correcting the distortion and increasing a deflecting power.

The invention/novelty of the invention relates to a photoelectric measuring device, particularly a manual exposure meter (1) for taking photographs, comprising a housing (2), a light-sensitive element (4) which is arranged inside said housing (2) and whose output signal is fed to a microprocessor (31) via an analog/digital converter (30), whereby the microprocessor (31) calculates the input variable coming from the analog/ digital converter (30) with other settings (film speed (ASA), correction value (KW), calibrating data (KD)) to form an exposure value (e.g. EV) which can be indicated on a display (5), in addition to a manually rotatable calculation ring (7) on which either an exposure time series or a series of aperture stops is disposed and can be placed opposite a series of aperture stops (12) or exposure times (11) arranged on the housing by rotating the calculation ring (7), whereby an exposure value series (14) is also disposed on the calculation ring (7) and is rotatable in relation to a housing marking (14).
摘要:
An integrated electronic article surveillance (EAS) and people counting system including an EAS system, a people counting system, and an alarm management unit. The alarm management unit accepts the EAS data signal from the EAS system and a people count signal from the people counting system for facilitating correlation of EAS and people count data. A method of monitoring a passageway and an alarm management unit associated with an integrated system are also provided. There is also provided a people counting system for determining a direction of travel of people including first and second people detection devices and a controller. The controller provides an output representative of a direction of travel in response to the outputs of the first and second people detection devices.

摘要:
A flexible video information storage and analysis apparatus stores a video information data base and a plurality of moving image content analysis algorithms for analyzing the video information in the data base. A user can manipulate a mouse to select one of the analysis algorithms. The selected algorithm is used to analyze video information in the data base. The apparatus records and displays plural streams of video information. Content analysis algorithms may be downloaded from a remote location. The apparatus takes appropriate actions in response to detected features in incoming video streams. Tile-based conditional-refresh video data compression is employed. A support structure efficiently supports several record-medium drive units. A tape back-up drive serves as an archiving mechanism for video data stored on hard disks. Recording of incoming video, and archiving and displaying of stored video, all proceed simultaneously.
