Patent number: 6906487Abstract: An antipinch circuit prevents the motor driven closure of an automotive window if a soft obstacle is compressed between the window and the top of the door frame, and the window is opened in response to the sensing of the obstacle. The circuit measures the motor torque (by measuring motor current) and the motor shaft speed (by measuring motor back EMF). The torque and motor speed are compared to “signatures” of these values in the case of the window closing normally against the top of the door frame, or against an obstacle, and either stopping or reversing the motor rotation accordingly.Type: GrantFiled: January 21, 2003Date of Patent: June 14, 2005Assignee: International Rectifier CorporationInventor: Xavier de Frutos

Patent number: 5147351Abstract: A safety seal for sterilizable containers that is closed by the temperature prevailing in the sterilizer. The closed seal then indicates the integrity of the container. The sealing mechanism in the illustrated embodiment is a pushbutton 100 that is subject to the force of a spring 102. The spring is made of a memory-retaining alloy that provides tension at a temperature above a transition temperature and forces the pushbutton into a locking state. The container can be opened once the pushbutton has been forced back, but the pushbutton cannot be returned to its locking position until it attains the transition temperature again.Type: GrantFiled: August 9, 1991Date of Patent: September 15, 1992Assignee: Wagner GmbHInventor: Peter Wagner

Patent number: 4914393Abstract: In an arrangement for use in an electronic circuit controllably put into operation by a battery and for indicating a consumption status of the battery, a measuring circuit measures a total time interval of operation of the electronic circuit. A processing circuit processes the total time interval into a calculated status for the battery. An indicator indicates the consumption status based on the calculated status. The processing circuit may comprise a memory for memorizing various current rates which are used in the electronic circuit and on which an arithmetic circuit calculates the calculated status. Alternatively, first and second measuring circuits may be used with first and second current rates memorized in the memory for the first and the second measuring circuits. Instead of the measuring circuits, a summing circuit may be supplied with a succession of the current rates repeatedly read out of the memory to sum up a total amount of current consumed by the electric circuit.Type: GrantFiled: August 26, 1988Date of Patent: April 3, 1990Assignee: NEC CorporationInventor: Koichi Yoshido
