Publication number: 20030011483Abstract: A wear detector for a suspension rope having a plurality of load bearing strands covered by a sheath includes a sensor at a surface of the sheath. The sensor senses a characteristic of the rope representing a predetermined amount of wear of the sheath. The sensed characteristic can be electrical contact with the strands, distance from the surface of the sheath to the strands, or change of color of the sheath surface.Type: ApplicationFiled: July 12, 2001Publication date: January 16, 2003Inventors: Miles P. Lamb, Karl B. Orndorff

Publication number: 20020053978Abstract: A method and apparatus are described for responding to a fire emergency at a facility by analyzing a plurality of fire threat conditions to determine possible responses to a fire emergency and selecting a response to the fire emergency for minimizing human casualties within the facility. The present invention may be characterized in one embodiment as a method for generating an automated response to an emergency that includes the steps of (a) receiving as input fire threat condition data for a facility; (b) analyzing the fire threat condition data to determine a matrix of possible responses to a fire emergency; and (c) selecting a response from the matrix of possible responses to minimize human casualties.Type: ApplicationFiled: December 6, 2000Publication date: May 9, 2002Inventors: Edward W. Peterson , Richard A. Grot

Patent number: 6186280Abstract: A vehicle lift assembly prevents accidental slippage of a vehicle therefrom. The vehicle lift assembly comprises a plurality of vertically disposed posts and a runway slidably coupled to the plurality of vertical posts. A hoist system supplies the force necessary for elevating the runway along the plurality of posts. A sensor arrangement detects whether the runway has tilted beyond a predetermined angular displacement. A lift control circuit controls the hoist system to elevate the runway selectively in a prescribed direction, and suspends operation of the hoist system, when necessary, to prevent the vehicle from accidentally sliding off the runway.Type: GrantFiled: September 14, 1999Date of Patent: February 13, 2001Assignee: Snap-On Technologies, Inc.Inventor: Donald A. Healy

Patent number: 6138798Abstract: The elevator safety device creates a false pit beneath the elevator frame using left and right laterally-spaced, fixed stop members fixedly attached to the car frame, and left and right laterally-spaced safety columns affixed to the pit floor and pivotable between an extended position in vertical alignment with the left and right stop members, respectively, and a retracted position clear of the car, the frame, and the left and right stop members. The safety columns are bumper-type devices designed to support full car weight should the need arise, and provides the ASME A17.1 minimum depth of pit for the refuge area. Actuators are operatively connected to the safety columns to pivot them between their extended and retracted positions. A pressure-sensitive detector located on the pit floor below the car detects the presence of a person on the pit floor. The actuators are electronically activated to pivot the safety columns from their retracted to their extended positions.Type: GrantFiled: January 14, 1998Date of Patent: October 31, 2000Inventor: Henry J. Macuga

Patent number: 6056088Abstract: Monitoring equipment for an elevator drive control includes two modules, a safety circuit sensor system and a motor-switching and/or brake-switching circuit, wherein the monitoring of a safety circuit and the consequential actions resulting therefrom takes place exclusively by means of electronic components while avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of elevator installations without a machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment can be ensured by the use of usual electronic components.Type: GrantFiled: September 21, 1998Date of Patent: May 2, 2000Assignee: Inventio AGInventor: Bernhard Gerstenkorn

Patent number: 5979607Abstract: A building having a plurality of floors, a plurality of detectors, such as smoke detectors, located on the floors, and an elevator system usable for moving building occupants between floors during an emergency condition, such as a building fire. The elevator system includes a control unit that controls movement of an elevator car between selected floors within an emergency evacuation zone for evacuation of building occupants to a designated evacuation assistance floor. The vertical movement of the elevator car is controlled relative to the detection of smoke within the building to increase the efficiency of emergency evacuation. The elevator and smoke detection systems are equipped with an emergency power source for operation in the event of a power outage.Type: GrantFiled: March 31, 1998Date of Patent: November 9, 1999Inventor: Thomas H.
