  • Minimal intrusion very low insertion loss technique to insert a device to a semi-rigid coaxial transmission line
    Patent number: 9041497
    Abstract: A signal conditioning apparatus can include a coaxial cable having at least one slot formed therein. A conductive film can be applied to the coaxial cable so as to cover each slot. A device mounting surface can be formed within the slot and a protection device can be mounted on the device mounting surface. A housing consisting of one or more interlockable portions can be coupled to the coaxial cable.
    Type: Grant

  • Switching apparatus with voltage spike prevention
    Patent number: 7609135
    Abstract: A switching apparatus has a conductive housing forming a chamber. The housing has an aperture enabling communication between the chamber and a housing exterior. A rod extends through the aperture, and has a first end within the chamber, and an opposed second end outside the chamber. The rod reciprocates over a range of motion between a first position in which a limited portion of the rod extends into the chamber, and a second position in which a greater portion of the rod extends into the chamber. The rod has a electrically insulative portion electrically isolating the first end from the second end, and has a conductive surface contacting the housing. A pair of electrical contacts are located in the chamber, and a shorting bar connected to the first end of the rod operates to bridge the contacts when the rod is in a selected position.
