  • Dual galvanic isolation barriers and monitoring systems and methods
    Patent number: 9829531
    Abstract: A system includes a first galvanic isolator, a second galvanic isolator, a sensor, and a monitoring module. The first galvanic isolator includes a first electrical insulator. The second galvanic isolator is connected in series with the first galvanic isolator and includes a second electrical insulator. The sensor generates a first output signal based on an electrical characteristic of one of the first and second electrical insulators. The monitoring module, based on the first output signal, selectively generates a signal indicative of a failure of at least one of the first and second electrical insulators.
    Type: Grant

  • Door prop
    Patent number: 5027471
    Abstract: A door prop device for the purpose of maintaining a hinged door in a propped-open position against the forces of spring tension, wind, gravity, or other causes, which will effectively function without damaging either the door or any adjacent structure and which will function on doors which pivot on vertical axes, horizontal axes, or any pivot axes orientations between vertical and horizontal. The device comprises a block-shaped prop member and a retainer member attached to the prop member. The retainer member is adapted to be placed over and engage with a hinge pin of an opened door hinge whereby the prop member is caused to assume an obstructing position in the space between the separated plates of the opened hinge. When it is desired to close the door, the door prop device is simply removed from the hinge and the door may then be closed.
