  • Patent number: 8172751
    Abstract: The present invention provides a surgical lamp for illuminating a surgical site. The surgical lamp includes a housing that defines an internal cavity. A light source is disposed within the internal cavity of the housing for producing a light field at a surgical site that is remote from the housing. A voltage sensitive device is disposed between the light source and the surgical site. The voltage sensitive device has light transmissive properties that change in response to a biasing voltage applied thereto. Control means control the biasing voltage to the voltage sensitive device.

  • Patent number: 8163235
    Abstract: The present invention provides a method and apparatus for removing chemical sterilant molecules from a medium, such as a carrier gas. In one embodiment, the apparatus includes a housing that defines an internal cavity. The housing has an inlet and an outlet fluidly communicating with the internal cavity. An electrode is dimensioned to be received in the internal cavity of the housing. The electrode is made of a material that is chemically active with respect to molecules of a chemical sterilant and conductive to electricity. The electrode is connected to a source of an electrical charge such that an electrical field gradient is formed in a region of space surrounding the electrode. The electrical field gradient is operable to force the chemical sterilant molecule toward the electrode.

  • Patent number: 8129579
    Abstract: An oxidizing liquid (20), such as hydrogen peroxide, is vaporized (18) and the vapor is used to deactivate nerve gas, blistering gas, or other biologically active substances such as pathogens, biotoxins, and prions. A second chemical compound (42) in vapor, mist, or fog form is used in conjunction with the oxidizing vapor. In one embodiment, the second chemical preconditions the biologically active substances to be deactivated more efficiently by the oxidizing vapor. In another embodiment, the second chemical boosts the reactivity of the oxidizing vapor. In another embodiment, the other chemical reacts with the oxidizing vapor to form an intermediate compound that deactivates at least some of the biologically active substances.

  • Patent number: 8025848
    Abstract: Hydrogen peroxide is vaporized (20) and mixed (30) with ammonia gas in a ratio between 1:1 and 1:0.0001. The peroxide and ammonia vapor mixture are conveyed to a treatment area (10) to neutralize V-type, H-type, or G-type chemical agents, pathogens, biotoxins, spores, prions, and the lip-,e. The ammonia provides the primary deactivating agent for G-type agents with the peroxide acting as an accelerator. The peroxide acts as the primary agent for deactivating V-type and H-type agents, pathogens, biotoxins, spores, and prions. The ammonia acts as an accelerator in at least some of these peroxide deactivation reactions.

  • Patent number: 7901618
    Abstract: A large convoluted space, such as a multi-story concourse of an airport is isolated and a chemical or biological agent in the concourse is deactivated. A plurality of deactivation gas sources (100) introduce a deactivation gas at multiple points along the concourse. Fans (66, 106) circulate the deactivation gas, sensors (110) sense concentrations of the deactivation gas at numerous points around the concourse and exhaust fans (66) exhaust air, spent deactivation gas, and some deactivation gas. A control processor (84) controls the generators, the circulation fans, and the exhaust fans in accordance with the gas concentrations sensed by the sensors to increase and decrease deactivation gas concentration in selected subregions of the concourse by increasing or decreasing generation, increasing or decreasing exhausting, or altering flow patterns among subregions.
