Gaseous Space Discharge Device Patents (Class 331/126)
  • Patent number: 9088916
    Abstract: A mobile device comprising a transmitter and a receiver used to wirelessly communicate with at least one network, wherein the mobile device is configured to wirelessly communicate with a first network and a second network, wherein the mobile device is configured to communicate with the second network during a handover procedure from the first network to the second network without disconnecting a link with the first network, and wherein the mobile device is configured to communicate with the second network during communication gaps between the mobile device and the first network during the handover procedure.

  • Patent number: 7626468
    Abstract: The median frequency in the emission from a microwave generator (14), which operates in a pulsed manner, is shifted when the generator (14) operates between passive reflectors (23) whose axes are parallel thereto. In the axial direction, the reflectors (23) are approximately the same length (L) as the generator (14), with length matching through telescopic rods being preferable. However, the frequency is governed primarily by the distance (D) between the reflectors (23-23) between which the generator (14) is operated. Once desired resonance conditions have been found, for example for injection of microwave radiation into the mechanical structure of an external arrangement, this frequency relationship can be fixed by the magnitude of the length of the preferably telescopic coupling piece (16) between the resonator (13) and the antenna (18).

  • Patent number: 7468638
    Abstract: An integrated transmit/receive (T/R) switch device comprises a substrate, an antenna port to couple with an antenna, a transmitter port to couple with a transmitter, and a receiver port to couple with a receiver. A receive path is provided between the antenna port and the receiver port, and a transmit path is provided between the antenna port and the transmitter port. The transmit path includes a first transistor on the substrate, and the first transistor is coupled in series between the antenna port and the transmitter port. A body node of the first transistor is unconnected, and the substrate is configured to provide a high impedance path from the first transistor to a reference voltage. A second transistor on the substrate is coupled in series between the receiver port and the reference voltage.

  • Patent number: 7388195
    Abstract: The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.

  • Patent number: 4507266
    Abstract: A glow discharge generating apparatus comprises, in a glow discharge chamber, an anode, a cathode for generating a glow discharge between the cathode and the anode upon application of a negative pulse, and a triggering electrode for starting the glow discharge. To stabilize the glow discharge, the electron density distribution in the vicinity of the surface of the cathode is made uniform only during at least part of a continuous period of the glow discharge.
