Inflatable Roof Safety Rigging System
US Patent:
4633974, Jan 6, 1987
Filed:
Nov 12, 1985
Appl. No.:

International Classification:
A62B 3700
US Classification:
182 3
Abstract:
A rigging system for retrieving a worker in the event of the collapse or tearing of a peripheral panel of an air-supported fabric roof employs one or more endless cables each entrained over pulleys located at the edge of the roof and inwardly therefrom. The worker is connected to one run of the cable by a safety line and harness. In the event of an accident, the cables are driven, for example by a detachable motor rotating one of the pulleys, to move the worker to the vicinity of the peripheral wall.

Rear View Mirror Positioning And Alerting Apparatus
US Patent:
5306953, Apr 26, 1994
Filed:
Aug 3, 1992
Appl. No.:
7/923461
Inventors:
Robert I. Weiner - Towson MD
International Classification:
G08G 104
US Classification:
307 101
Abstract:
A system for automatically controlling the position of a tractor-trailer rearview mirror to maintain unobstructed vision in the mirror during turns employs a pair of ultrasonic transducers mounted on the external rear wall of the tractor on opposite sides of the centerline thereof so as to project ultrasonic sound beams onto the forward wall of the trailer. A control circuit determines the difference in the two path lengths, indicating the degree of turning of the vehicle, to generate control signals to a mirror rotating motor. A third transducer may be mounted for rotation with the mirror and directs an ultrasonic beam along the zone immediately beside the trailer for detecting persons or objects within the zone and actuating an alarm in the event of such detection.

International Classification:
E04H 400, A47H 1300
US Classification:
4503
Abstract:
In order to prevent the edge of a floating pool cover from rolling downwardly into the water, as would occur if a child fell or stepped onto the cover, upwardly open channels, the outer walls of which are notched at spaced intervals, are affixed to the pool walls immediately above the water level and extend along substantially the entire periphery of the pool, and anchors are attached to the edges of the cover at the same intervals as the notches, each anchor projecting laterally from the cover and having a shank terminating in a bulbous end which may be dropped into the channel.
