  • Patent number: 9675155
    Abstract: A light transmitting device has a flexible elongated substantially flat band of high clarity light transmitting polymeric material. An LED is mounted by a mounting structure immediately adjacent but not embedded in an end of the band, and electrical wiring extends from the LED to a battery. The band is incorporated in a container (e.g. backpack, fanny pack, clutch) made at least partially of fabric so that light emitted from the band is visible from the exterior of the container. A battery and printed circuit board are mounted in the interior of the container, and an electrical switch for operating the LED is accessible from the exterior of the container. A flap stitched onto the front panel of the container covers the band and holds it in place but allows light to get through.

At least one battery powers the LED. A module including a printed circuit board, electrical switch, and the LED and battery, is positioned within a housing having open ends so that one or both ends of the light transmitting element receive light directly from an LED. A number of button batteries, or a rechargeable battery with USB port, may be mounted on the module, and the circuitry of the printed circuit board may include an integrated circuit.

  • Publication number: 20120234336
    Abstract: Human lip exfoliation is provided using a device to apply flowable exfoliant material to the user's lips, and then effecting powered vibration of a tip of the same device to gently exfoliate the user's lips. The device can include an exfoliator unit and a lip gloss unit, with a magnetic coupling between the units to hold them together until positively separated, yet movement of the lip gloss unit will not result in discharge of exfoliant. The exfoliator unit has a silicone applicator tip with a number of integral silicone bristles for contact with a user's lips. The tip is connected by a passage to a chamber containing exfoliant, and a check valve can be provided between the passage and chamber.

  • Patent number: 8134128
    Abstract: A method of analyzing a remotely-located object includes the step of illuminating at least a portion of a targeted object with electromagnetic radiation to induce a phase transformation in the targeted object, wherein the phase transformation produces an emitter plasma, which emits terahertz radiation. The method also includes the step of ionizing a volume of an ambient gas to produce a sensor plasma by focusing an optical probe beam in the volume and the step of detecting an optical component of resultant radiation produced from an interaction of the focused optical probe beam and the terahertz radiation in the sensor plasma. Detecting an optical component of the resultant radiation emitted by the sensor plasma facilitates detection of a characteristic fingerprint of the targeted object imposed onto the terahertz radiation produced as a result of the induced phase transformation.

  • Patent number: 7718969
    Abstract: A method for generating amplified terahertz radiation includes inducing a first volume of a gas to produce a seed plasma and emit pulsed seed terahertz radiation by focusing an optical seed beam in the first volume. The seed terahertz radiation is then amplified by focusing an optical gain beam to produce a gain plasma in a second volume overlapping with the pulsed seed terahertz radiation remote from the seed plasma. The method may be implemented in a system for detecting and analyzing a remotely-located object such as an explosive material, a biological agent, and a chemical agent.

  • Patent number: 7531802
    Abstract: A method of analyzing a remotely-located object includes the steps of inducing a volume of an ionized ambient gas to emit pulsed terahertz radiation directed toward a targeted object by focusing an optical pump beam in the volume and ionizing another volume of the ambient gas to produce a sensor plasma by focusing an optical probe beam in the other volume of ambient gas. The interaction, in the sensor plasma, of the focused optical probe beam and an incident terahertz wave, which is produced by the targeted object reflecting, scattering, or transmitting the pulsed terahertz radiation, produces a resultant radiation. Detecting an optical component of the resultant radiation emitted by the sensor plasma facilitates detection of a signature of the targeted object imposed onto the incident terahertz radiation.
