Abstract: A parking area entrance or exit barrier includes a control system which receives inputs from various accessories associated with the operation of the barrier, and which provides control signals to the various accessories of the barrier. One of the accessories includes a sensor attached to the barrier. The sensor senses an accident event, such as contact between the barrier and a vehicle. Whenever an accident event is sensed, the control system creates an accident event log of information concerning the accident event. The accident event log may include video images of the barrier, a position of the barrier, a movement direction and speed of the barrier, and an approximated speed of the vehicle. The control system may also monitor a performance of the various accessories of the barrier and create a performance log relating to any malfunction of the accessories.

Abstract: A parking area control and management system employs a card reader, which reads identification information from a card commonly carried by a person, such as a driver's license or credit card. A record is made of the identification information upon entrance of a vehicle into the parking area. The person may subsequently leave the parking area on foot and regain entry to the parking area by presenting the same card. Later, the same card is used to exit the parking area, via the vehicle, and to validate that the same person is leaving with the vehicle. The parking area control and management system also includes sensors, such as loop detectors and electric eyes, to determine if a second vehicle or a pedestrian follows behind a vehicle entering into, or exiting from, the parking area.

Abstract: A door, such as a fire door or a security gate, for blocking a throughway or opening in an exterior or interior wall of a building, such as a doorway or countertop window, has an open position and a closed position. A force, such as gravity, a counter weight or a spring, tends to move the door toward its closed position. In the case of the fire door, a disengageable stop holds the door in its open position. The disengageable stop includes a brake actuator for releasing a brake. An expandable linkage, having a normal length and having an elongate length when an external force is applied thereto, has a first end connected to the brake actuator. A second end of the expandable linkage is connected to a fire condition sensitive device, which releases the second end upon a fire indicative condition. With the fire door, or any other type of door, a DC generator is connected to the door and produces power as the door moves from its open position to its closed position.

Abstract: A flotation assembly designed to keep an individual afloat in water comprising a size adjustable harness adapted to fit the torso of an individual, to which are attached bottle closure devices. The closure devices are designed to have empty bottles inserted therein so as to form a substantially water-tight seal. The number of attached closure devices, and the size of the bottles inserted therein are chosen so that the degree of buoyancy desired is obtained, given the size of the individual and the purpose for which the buoyancy is required. Different types of closure devices are disclosed.

Abstract: The elevator type gage assembly has a plurality of vertically spaced support members, that can be secured to an associated gage, each of which has a gage template operatively positioned therein and wherein a vertically extending support rod is secured to and extends between a pair of the support members and it has an indicator sleeve bracket rotatably and vertically slidably engaged therewith which bracket has a portion for engaging a laterally outer end of a support member to aid in adjusting the gage while an indicator is operatively secured to the indicator sleeve bracket; a contact arm is pivotally carried by the indicator sleeve bracket with an end portion for engaging a laterally outer end of a gage template and a second end portion to engage the indicator operating pin to provide a reading on the indicator of the position of the slide template in the associated gage.

Abstract: An article positioning fixture to position a plurality of articles in accurate assocation including an elongate metal base on which a plurality of locator inserts are positioned to receive individual matrix boxes thereon, each box carrying a test article therein and accurately located in relation thereto with common areas of the test articles exposed in accurately positioned relationship to each other, and the fixture also has tapped bushings in the locator inserts for securing the matrix blocks to the locator inserts but which bushings can be replaced readily if worn.

Abstract: A matrix balancing fixture that has a pair of fixedly positioned spaced cartridges positioning opposed top and bottom templates for movement towards each other for engaging a test article at spaced vertical portions thereof with the test article being in an open ended box positioned between the cartridges; the fixture having a pair of indicators having operating members slidably mounted therein positioned on upper portions of the cartridges in spaced relation in a horizontal plane and control members connecting the templates on a cartridge to the indicators on the cartridge for convenient reading thereon.

Abstract: A gage including a base having a reference surface with a bore extending into the base usually perpendicular to such surface, a gage unit on the base and including a cylindrical barrel section positioned in the bore, a slidable member in the barrel section with an article locater device operably carried thereon. The slidable member operably positions a gage member thereon in opposed spaced relationship to the article locater device.
