  • Patent number: 7614117
    Abstract: The quick-release hinge includes a first member, a second member, an actuation member, and a knuckle that may be attached to one of the first or second members. The first member may have a first locking element and a first abutment surface configured to abut a surface of an object. The second member may have a second locking element and a second abutment surface configured to abut a second surface of the object. The second locking element may be configured to attach to the first locking element in order to connect the hinge to an object. The actuation member may be attached to the first locking element so that when the actuation member is actuated, the first locking element may rotate about one revolution or less in order to detach from the second locking element and disconnect the hinge from the object.

  • Patent number: 7354287
    Abstract: An electrical connector includes a housing that may form a first contact channel and a second contact channel. A first contact having a longitudinal axis may be disposed within the first contact channel, and a second contact may be disposed within the second contact channel. A shorting arm may be configured to move generally parallel to the longitudinal axis of the first contact between a first position and a second position. When the shorting arm is in the first position, the shorting arm electrically connects the first contact with the second contact, and when the shorting arm is in the second position, the shorting arm is separated from the first and second contacts.
