  • Publication number: 20150082702
    Abstract: Disclosed is a pivotally mounted window and screen assembly. The device includes a T-shaped vertical support bar that is hingedly attached to a screen and a window frame, in which a window sash is mounted. The window frame is adapted to swing outward, while the screen is adapted to swing inward so that the window sash is unobstructed and can swing open the full 180 degree range relative to the vertical support bar. The present invention further includes a locking mechanism that secures the window sash and the screen in an open position. In this way, a user can open the window to access and clean the exterior side of the window without extending any portion of the body outside of a building. The present invention may be constructed to be installed into any window opening of a building.

  • Patent number: 6107815
    Abstract: An apparatus for function testing of electronic circuits includes a tester array having a terminal. A test circuit has at least two resistor elements, a common circuit node connected to the resistor elements for connection to the terminal of the tester array, and terminals of the resistor elements each being remote from the circuit node for connection to a respective output of an electronic circuit to be tested. A testing method for function testing of electronic circuits with such an apparatus includes placing the electronic circuit into a state in which signals are present at an output of the electronic circuit to be tested. The electronic circuit is function tested with respect to a resultant signal being established at the common circuit node.

  • Patent number: 5442312
    Abstract: An integrated circuit for generating a reset signal includes a circuit part having two first transistors being connected in series between terminals for a first and a second supply potential and each having a respective one of first and second mutually complementary channel types. A serial network acting as a voltage divider circuit is connected between the terminals for the first and the second supply potentials. The serial network includes at least two second transistors each having a respective one of the mutually complementary channel types and at least one element having a voltage drop during operation. The sources of the transistors of the first channel type are connected to the terminal for the first supply potential. The sources of the transistors of the second channel type are connected to the terminal for the second supply potential. The drains of the two first transistors form a first circuit node at which a reset signal is created in operation.
