Patent number: 8910663Abstract: A uni-directional valve for an air path of a ventilation device. A flexible valve element is held biased in a housing of the uni-directional valve to close at least one air passage located in a sealing section and with a sealing portion to at least partially open the air passage if the valve element is impinged by a sufficient air pressure against the bias. The valve element is designed as cylinder and the sealing portion is located on the lateral surface of the cylinder. The sealing portion is located opposite to a support portion located on the lateral surface of the cylinder. The support portion interacts with a support section of the housing. The distance between the support section and the sealing section of the housing is smaller than the distance between the support portion and the sealing portion in the unbiased state of the valve element.Type: GrantFiled: September 22, 2011Date of Patent: December 16, 2014Assignee: Moldex-Metric, Inc.Inventors: Frank Kern, Torben Skov

Patent number: 8412923Abstract: An integrated circuit resides on a circuit board. During operation, the digital controller integrated circuit produces control signals to control a power supply for delivery of power to a load. The integrated circuit can include multiple connectivity ports, on-board memory, and mode control logic. The multiple connectivity ports such as pins, pads, etc., of the integrated circuit can be configured to provide connections between internal circuitry residing in the integrated circuit and external circuitry residing on a circuit board to which the integrated circuit is attached. The mode control logic monitors a status of one or more connectivity ports of the integrated circuit to detect when a board handler places the digital controller in a power island mode in which the integrated circuit is powered so that the board handler can access (e.g., read/write) the memory in the digital controller integrated circuit while other portions of the board are unpowered.Type: GrantFiled: February 9, 2010Date of Patent: April 2, 2013Assignee: International Rectifier CorporationInventors: Robert T.
