Additionally, a method of controlling at least two devices includes exposing a reed switch apparatus to a single magnetic field. Yet another method includes activating a device via the use of a single reed switch mounted to a portion of a warehouse structure.Type: GrantFiled: February 7, 2012Date of Patent: October 21, 2014Inventor: Glendell N.

Patent number: 8847715Abstract: A permanent magnet is pivotally mounted in a top spacer layer of a switching device and rests on a flex arm created in an underlying flex circuit layer. The underside of the flex arm rests on a thin bar formed in a lower spacer layer beneath which lies a base layer including an electromagnet. Activation of the electromagnet causes rotation of the flex arm to thereby close and open electrical contacts formed respectively on the underside of the flex arm and on the top surface of the base layer.Type: GrantFiled: September 26, 2012Date of Patent: September 30, 2014Assignee: Telepath Networks, Inc.Inventors: Kevin Wilson, Robert Tarzwell, Patrick McGuire
