Patent number: 5201906Abstract: A control system for a revolving door includes an ultrasonic sensor having multiple sensor heads. The door has a housing and multiple movable compartments formed by door wings. The sensors emit energy waves into the housing in bursts, then receive echoes from any objects, including people, in the compartments. The sensors are activated when the door is activated by an authorized user. A controller stores a binary "echo" or "no echo" signal in memory in response to an emitted energy wave. The system determines a maximum height of an object or person in a compartment, then measures the total amount of time that it detects something above a selected percentage of the maximum height. When this time reaches a predetermined amount, the system interprets that as "piggybacking" (two individuals in one compartment). The system also interprets signals that go above, drop below, and then rise above the selected percentage again as piggybacking.Type: GrantFiled: September 9, 1991Date of Patent: April 13, 1993Assignee: Milan SchwarzInventors: Milan Schwarz, Robert Mayer

Patent number: 4947765Abstract: The security method and apparatus relates to an electronically controlled latching mechanism which is adapted for use with a closure disposed on a vestibule. The closure is used to seal or close off a passageway or entrance between the vestibule and a protected or secured area. A security unit generates a signal which drives the latching mechanism from a latched to an unlatched position whenever an access control circuit generates an enablement signal. The enablement signal is generated whenever the vestibule is sealed and the weight of the person or persons within the vestibule, as determined by an electronic scale, compares with a predetermined weight value. A closure switch senses when the vestibule is closed, and a weight sensing mechanism senses the weight of a person or person disposed within the vestibule.Type: GrantFiled: April 25, 1989Date of Patent: August 14, 1990Assignee: National Bulletproof, Inc.Inventor: Frederick F.

Patent number: 4534131Abstract: A revolving door system has a central axis defining a center shaft and three wing hangers rigidly joined and extending in a equidistant spaced apart relationship about the center shaft's upper portion.A pair of facing substantially semicircular walls, spaced apart to define regions of ingress and egress, partially surrounds the wings and shaft on opposite sides.The system allows free passage of persons in an authorized direction while preventing, and driving out, intruders attempting to pass in an unauthorized direction. If an intruder enters the system in an unauthorized direction, the door stops before the intruder has free passage to the other side, reverses direction and forces the intruder back toward the entrance. In one configuration, the door then rotates in its forward direction to permit the authorized passenger to escape the system, but not far enough to allow the intruder to pass. In another configuration, the reversal of the door allows the passenger to escape from the side in which it entered.Type: GrantFiled: October 31, 1983Date of Patent: August 13, 1985Assignee: Heise ManufacturingInventors: Michael D.
