Patent CA-1299000-C (CA)
Inventor: QUANTE HEINRICH
IPC: E04H12/18
Filed: 1987-11-20
Granted: 1992-04-21
Abstract: Abstract of the Disclosure The specification describes a barrier post for access roads, parking areas and parking stalls.  A base, which is secured to the road surface, is joined to a tube which can be pivotted about a hinge joint from the horizontal to the vertical and vice versa.  The hinge joint is divided into offset upper and lower joints.  The upper joint directly connects the tube and the base, while the lower joint connects the base with the lower portion of a movement spindle, arranged vertically within the tube, and rotatable by a motor.  The opposite end of the movement spindle is guided by a movement nut which moves on the movement spindle.          This arrangement allows the barrier to be safely raised or lowered with very little energy and avoids pinch points at the hinge joint.

Abstract: Sensor means comprise three cylindrical bodies having sensing windows of constant width for all the bodies, or varying according to an exponential law as a function of the bearing angle in the case of the third body (C1).   One of the first two bodies (C2) has a skirt masking part of the window, to make this body responsive to the elevation.   The light signals available in the three bodies are carried by optical fibres (L11 to L31) of different lengths to a photodetector (PD) connected by a capacitor (CL) to a logarithmic amplifier (AL) followed by an analog/digital coder (CAN) and processing means (DT).     It is then possible to measure the elevation and bearing of an incident laser pulse, its duration, and possibly its repetition period.
