US Patent:

56274394, May 6, 1997

Filed:

Jul 8, 1996

Appl. No.:

8/677600

Inventors:

Richard A. Gregory - Chicago IL
Nicholas Kassetas - Vernon NJ

Assignee:

Inventio AG - Hergiswil

International Classification:

H02P 300

US Classification:

318480

Abstract:

An apparatus for detecting an object adjacent an elevator door includes a housing (47) mounted at an upper edge of a car door opening (38) and in which are mounted a plurality of short range detector pairs (50) and a plurality of long range detector pairs (53). Each short range detector pair includes a transmitter (14,25,40) for generating a relatively short range infrared beam (18,27,42) toward a path of travel (16) of an elevator door (17) across the door opening and a short range receiver (15,26,41) for detecting a reflection (31) of the beam from a facing surface (17b) of the door and generating a short range beam detection signal. Each long range detector pair is positioned adjacent an associated one of the short range detector pairs and includes a transmitter (19,28,43) for generating a relatively long range infrared beam (21,30,45) across the path of travel and a receiver (20,29,44) for detecting a reflection (23) of the beam from an object (22) near the door opening and generating a long range beam detection signal. A control (11) is connected to each detector pair for turning on the transmitters and for reopening the closing door in response to the long range beam detection signal. The control responds to each short range detection signal during closing of the door to disable the associated long range transmitter and responds to termination of the short range detection signal during opening of the door to enable the associated long range transmitter to prevent detection of the moving door by the long range receivers from reopening the door.

Abstract:

A vandal resistant push button assembly has a guide ring attached to a mounting plate spaced from a face plate such as an indicating and announcing device or a modular wall assembly of an elevator car. The guide ring has a first shoulder which cooperates with a snap ring engaging a first annular groove formed in the guide ring for retaining the ring in an opening formed in the mounting plate. There is play between the periphery of the opening in the mounting plate and the outer diameter of the guide ring such that the guide ring can be aligned with respect to an opening in the face plate and the snap will cover the gap defined by the play. A push button slidably extends through the guide rings on first and second guide surfaces to actuate a switch and a second shoulder formed on the push button engages a stop surface on the guide ring to prevent further travel in the actuation direction. Spring forces originating from the switch press the push button forward to a rest position at which a spring clip engaging a second groove formed in the push button abuts an end of the guide ring. In this position, a seamless spherical surface is formed by the push button and the guide ring at the face plate.

Abstract:

A fulfillment test of a computing system having components is performed within a build-to-order test phase. Responsive to the fulfillment test failing, the component that most contributed to the fulfillment test failing is replaced, regardless of whether the given component was determined to be suspect or marginally defective pursuant to a fabrication test previously performed within a build-to-plan test phase. Any other component of that contributed to the fulfillment test failing and that was determined to be suspect or marginally defective pursuant to the fabrication test previously performed within the build-to-plan test phase is also replaced.
