  • Patent number: 9421194
    Abstract: The American Cancer Society estimated that in 2009, 1,479,350 new cancer cases would be diagnosed in the United States of which 219,440 would be lung and bronchus related. The standard treatments for NSCLC include surgery, chemotherapy, radiation, laser and photodynamic therapy, all with various success rates depending on the stage of the cancer. National Cancer Institute assesses, however, that results of standard treatment are generally poor with only a 15 percent 5-year survival rate for combined cancer stages. Challenges facing the current chemotherapy drugs include excessive toxicity to healthy tissues and limited ability to prevent metastases. A dual drug delivery system described herein selectively targets the lung to deliver anti-cancer drugs and inhibit the formation of metastases.

  • Patent number: 9410876
    Abstract: An apparatus and method for determining the average molecular weight of a complex mixture from a plurality of test samples of the complex mixture are disclosed. The method includes a) providing a chamber having two fixed conditions and one variable condition selected from three state variables of temperature, pressure and volume; b) introducing a test sample of known mass into the chamber; c) setting operating conditions of the state variables such that the test sample will be fully vaporized into a gaseous state without decomposition or chemical reaction; and d) measuring the change of the variable condition after full vaporization of the test sample is achieved. Steps b-d are repeated for several test samples having different masses. The average molecular weight of the complex mixture is determined as a linear gradient (slope) of the relationship for the change of variable condition as a function of test sample mass.

  • Publication number: 20160195657
    Abstract: While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.

  • Patent number: 9339335
    Abstract: Ultra-short pulsed laser radiation is applied to a patient's eye to create a row of bubbles oriented perpendicular to the axis of vision. The row of bubbles leads to a region of the eye to be ablated. In a second step, a femtosecond laser beam guided through the row of bubbles converts it to a channel perpendicular to the axis of vision. In a third step, a femtosecond laser beam is guided through the channel to ablate a portion of the eye. Using a femtosecond laser with intensity in the range of 1011-1015 W/cm2 for the second and third steps facilitates multi-photon ablation that is practically devoid of eye tissue heating. Creating bubbles in the first step increases the speed of channel creation and channel diameter uniformity, thereby increasing the precision of the subsequent multi-photon ablation.

  • Publication number: 20160123833
    Abstract: A liquid metal leak detector system including a direct current (DC) power supply and a plurality of analog to digital converters connected to the DC power supply. Each converter includes a liquid metal switch, where the liquid metal switch is closed in event of a liquid metal leak since the liquid metal leak causes electrical continuity between a conductive sheeting and a housing for liquid metal. The converter also includes a comparator connected to both the liquid metal switch for converting an analog signal into a digital signal, wherein the digital signal is configured such that a high signal constitutes no leak and a low signal constitutes a leak. An AND gate is also connected to each of the plurality of converters for combining all of the digital signals output from the converters, the AND gate configured such that the AND gate outputs a high signal if all of its inputs are high and a low signal if any input is low.
