Eric Glenn Hufstedler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20180166246
    Abstract: Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components. In some embodiments, the fuse devices can comprise pyrotechnic features.

  • Patent number: 6476697
    Abstract: A modular, multi-phase electrical relay contactor assembled from a number of electrical relay contactor units. Each unit has a housing, an electromagnetic motor located within the housing, a pair of stationary contacts attached to the housing, a moveable contact, and a moveable contact carrier. The moveable contact carrier is engaged with the moveable contact and has a metallic clapper plunger attached to its upper end. A protrusion extends from one side of the moveable contact carrier and an aperture, sized to receive the protrusion of another electrical relay contactor unit, is formed through another side of the moveable contact carrier. A plurality of units are adapted to be connected together such that when engaged, the protrusion extending from the moveable contact carrier of a forwardly located unit will fit into the aperture formed in the moveable contact carrier of a rearwardly located unit, thereby providing synchronous movement of the plurality of moveable contact carriers and the moveable contacts.

  • Patent number: 6441707
    Abstract: A electrical conductor relay. The relay has a unitary, non-conducting, chassis/bobbin assembly with a base portion, a bobbin portion, and an upper portion with a window and a plunger slide passage. An electromagnetic coil is located around the bobbin portion and a magnetic metal core passes through the bobbin and extends partially into the window. First and second electrodes are attached to the chassis/bobbin assembly. The first electrode has a first electrode contact, and the second electrode has a top end. A plunger slide member is positioned within the plunger slide passage and has a magnetic metal plunger plate affixed to its bottom. The magnetic metal plunger plate is movably located in the window and is spaced above the magnetic metal core extending up into window. An armature with a fulcrum end and a rearwardly extending spring attachment end and a front end with an armature contact is provided. The armature pivotally engaged with the plunger slide member.
