摘要:
A security sensor equipped with a sighting device in which respective optical axes of a beam projector and a beam receiver can be adjusted easily and quickly. The beam receiver A includes an adjustment (50) for adjusting the optical axis, a mirror-equipped sighting device (C) having a viewing window (12) through which viewing is possible from a lateral side of the beam receiver (A), a light emitting element (8) and a mirror (14) accommodated therein for presenting an image of the beam projector (B), and a lamp control (6) for changing a status of the light emitting element (8) in correspondence with the amount of light received from the beam projector (B).
摘要:
An intruder detection system for sensing infrared radiated by an intruder through a window-pane and detecting the intrusion through the reception of an output from the infrared sensor, in which the system includes a light emitter for projecting infrared ray toward a detection area, and a light acceptor for receiving at least part of the infrared ray projected by the light emitter through an obstruction detection optical path, the light emitter and the light acceptor being located in opposite positions with respect to the window-pane.
摘要:
The system consists of separate spaced units (1) and (2) including a projector (12) and a detector (21), respectively. For aligning the projector and detector the output of the detector (21) is relayed to the unit (1) by a transmitter (27) and receiver (13) connected by a cable (L) or by wireless or optical transmission. The projector (12) can thus be adjusted by watching the indicator (14). The detector (21) can then be adjusted by matching the indicator (26) or (28).

The drive diagnosing device 1 includes a portable device main body 2, which is electrically powered by a battery 8 built in the device 1 and which includes a control unit for acquiring a driving behavior from the operation of an automotive vehicle, which has been detected by an operation detecting (acceleration) sensor 5 and then determining the driving behavior to thereby diagnose such driving, the device main body 2 being disposed at an arbitrarily chosen site within the automotive vehicle. The operation detecting sensor 5 is kept in a constant drive condition, and a driving behavior capture initiating unit 12 is provided for causing the control unit 6 to initiate the capture of the driving behavior from the operation detecting sensor 5 and for subsequently determining the driving behavior.

A device for determining an alert condition in a system for a gate which device is usable easily in any building and is suitable for a building whose security is not strict, is provided. The system 1 includes: an access device 4, a gate 2 being opened or opening of the gate 2 being permitted at least after the access device 4 is accessed; a full closing detector 3 detecting full closing of the gate 2; an object detector 5 including at least one sensor 5a or 5b detecting an object in a detection area 50a or 50b which is near the gate 2 and within at least one of two zones B and C; and the device 6. The device 6 is connected to the detectors 3 and 5, and determines the alert condition after a predetermined combination of full-closing detection or non-detection and object detection or non-detection occurs.

A vehicle detecting sensor assembly (1) includes a microwave module (4) and a radome (5) for detecting the presence or absence of a parked vehicle, parked in a predetermined parking area (3), according an FMCW scheme. A shielding member (10) is provided on each of left and right sides, each of upper and lower sides or each of upper and lower and left and right sides of the module so as to protrude in a direction, conforming to the direction of transmission of a microwave, so that a detection range angle by the microwave can be varied in dependence on the position of the sensor and the size of the parking area, and a so disposed that the distance of separation between the module and the radome, through which the microwave passes, may lie in the vicinity of n times the half-wave length of the microwave.
