Abstract:
An apparatus and a method for operating a sealed beam lamp containing an ionizable medium are disclosed. The lamp includes a sealed chamber, a pair of ignition electrodes, a substantially flat chamber ingress window, and a laser light source disposed outside the chamber producing laser light. Laser light is focused to a first focal region coinciding with an ignition region disposed between the ignition electrodes. The ionizable medium at the ignition region is ignited with the laser. The laser light is focused to a second focal region coinciding with a plasma sustaining region not co-located with the plasma ignition region.
Abstract:
A method and apparatus for a sealed high intensity illumination device are disclosed. The device is configured to receive a laser beam from a laser light source. The device has a sealed chamber configured to contain an ionizable medium. The chamber has a substantially flat ingress window disposed within a wall of the integral reflective chamber interior surface configured to admit the laser beam into the chamber, a plasma sustaining region, a plasma ignition region, and a high intensity light egress window configured to emit high intensity light from the chamber. The chamber has an integral reflective chamber interior surface configured to reflect high intensity light from the plasma sustaining region to the egress window. There is a direct path of the laser beam from the laser light source through the lens and ingress window to the lens focal region.
Abstract:
An apparatus and a method for operating a sealed high intensity illumination lamp configured to receive a laser beam from a laser light source. The lamp includes a sealed chamber configured to contain an ionizable medium having a plasma sustaining region, and a plasma ignition region. A high intensity light egress window emits high intensity light from the chamber. A substantially flat ingress window located within a wall of the chamber admits the laser beam into the chamber. The lamp includes means for controlled increasing and decreasing a pressure level within the sealed chamber while the lamp is producing the high intensity illumination.

Abstract:
An illumination device with an integrated thermal imaging sensor and method for using the same are disclosed. The device includes a solid state illumination source, and a thermal imager comprising a multi-pixel heat sensing device. A controller is configured to control the thermal imager, and a power source is configured to supply power to the illumination source, the thermal imager, and the controller.
Abstract:
A method and device are presented for providing patient safe light to a wound. The device includes a radiation source producing flora lethal radiation wavelengths, a radiation conduit detachably optically coupled to the radiation source, and a patch remotely located from the radiation source configured to at least partially conform to a surface contour of the wound. The patch includes a flexible panel formed of a radiation transmitting material able to withstand sterilization, including at least one surface with a disturbed surface area configured to emit radiation upon the wound.
