The sensors provide an indication of different levels of relative movement between the door panel and the door frame member at an interface (28) between them. Such relative movement includes an increase in a gap between them that corresponds to a situation when an object is at the interface (28) and may be caught. The sensors (30, 50) respectively provide an indication of when an object may become caught and when one has. Automated movement of a door is controlled responsive to an indication of the presence of an object in a location where the object may become caught during automatic movement of the door.Type: GrantFiled: June 22, 2011Date of Patent: March 25, 2014Assignee: Otis Elevator CompanyInventors: Tadaaki Nabetani, Jiro Kashima, Atsushi Yamada

Patent number: 8662564Abstract: Hinged assemblies, and children's products including at least one hinged assembly, include a base member and a hinged member operatively and pivotally coupled to the base member to define a hinge. The hinge is configured to release if an obstruction is positioned between the hinged member and the base member while the hinged member is being closed and if a closing torque is greater than or equal to a release torque. The hinge also may be configured to not release when an opening torque is applied when the hinged member is in its open position even when the opening torque is greater than the release torque.Type: GrantFiled: January 12, 2012Date of Patent: March 4, 2014Assignee: Mattel, Inc.Inventors: William R. Howell, Charles D. Smith, Jon Paul Castiglione

Patent number: 8646206Abstract: Embodiments of the invention are directed to a system of presence detection in a door assembly for the prevention of patient/detainee suicide, comprising: a door frame, wherein the door frame defines an opening; a door mounted in said opening, wherein the door is allowed to operate from open to closed position with respect to the door frame; a presence sensing arrangement, which allows detection of the presence of an object near the surfaces of the door, door frame, and the upper and lower surfaces of the door or door frame from open to closed position. Placement of presence sensors on the upper or lower surfaces of the door allows presence detection when a patient/detainee attempts to drape a ligature object across or underneath said surfaces. A control system may monitor the system, and can activate an alarm system for early detection and prevention.Type: GrantFiled: January 23, 2012Date of Patent: February 11, 2014Assignee: Door Control Services, Inc.Inventor: Jimmy Don Gilchrist

Patent number: 8635809Abstract: The invention specifies an anti-trapping device, comprising a motor for driving a pivotable actuating element of a motor vehicle, a sensor for contactlessly identifying an obstacle in the way of the actuating element with an electrode, which has a plurality of segments for producing an external electrical field with respect to a mating electrode and a control unit. The electrode extends in a radial direction with respect to the pivotable actuating element and is split in the radial direction into the plurality of segments, which can each be evaluated separately for the purpose of generating an interference signal. The control unit is designed to drive the motor as a function of an interference signal from one of the segments. Such an anti-trapping device has particularly high flexibility when driving the pivotable actuating element if an obstacle in the way of the pivotable actuating element has been detected.Type: GrantFiled: July 28, 2007Date of Patent: January 28, 2014Assignee: Brose Fahrzeugteile GmbH & Co.

Publication number: 20140020296Abstract: A high-pressure mine door assembly for use in mine shafts configured with opposing wings, which enable the door to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door. The door assembly is configured in a 12-6 pitch orientation, requiring only a ? rotation of the wings of the door assembly to fully open the door. Such a configuration also negates the effect of air pressure on operation of the door, as regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.Type: ApplicationFiled: February 22, 2013Publication date: January 23, 2014Applicant: AMERICAN MINE DOOR CO.Inventors: Daniel S. Zenisek, Robert H. Chorman

Patent number: 8615927Abstract: An obstacle detection system includes a first component and a second component. The motor is configured to move the second component toward the first component. Radio frequency identification tags (RFIDs) are connected to one of the first component and the second component. A controller is operatively connected to the motor and has a transmitter operatively connected to the other of the first component and the second component. The transmitter is operable to create a magnetic field between the first component and the second component. Each of the RFIDs is operable to provide a respective signal in response to the field. The controller is configured to modify power delivery from a power source to the motor when the respective signals received by a receiver change due to at least a portion of the magnetic field being at least partially blocked or attenuated. A method of detecting an obstacle is also provided.Type: GrantFiled: November 23, 2011Date of Patent: December 31, 2013Assignee: GM Global Technology Operations LLCInventors: Hesham A.
