  • Point of care sensor systems
    Patent number: 11965883
    Abstract: Provided are point of care sensor systems that include portable readers and disposable cartridges for receiving and analyzing samples. A cartridge may be equipped with one or more sensor channels, each containing one or more sensors. After providing a sample to a cartridge, the cartridge can be inserted into a reader, which can interact with the cartridge to perform on-cartridge sensing and receive signals indicating the presence and/or quantity of one or more targets in the sample. Examples of cartridges can include cardiac panels, sepsis panels and the like. In some embodiments, the same sensor hardware may be configured for multiple measurements of different targets conducted at different time frames. Also provided herein are novel on-cartridge solid and liquid reagent storage and delivery mechanisms.

  • APPARATUS AND METHOD OF MULTI-BIT AND GRAY-SCALE HIGH DENSITY DATA STORAGE
    Publication number: 20150302884
    Abstract: A data storage apparatus and method of storing data are disclosed. An array of irradiation sources are provided for writing on an optically stimulated luminescence (OSL) material. The OSL material includes data storage pixels or spots. Each pixel or spot includes gray-scale levels with higher order bits and variable intensity. A light source stimulates luminescence on the OSL material.

  • Protected alloy surfaces in microchannel apparatus and catalysts, alumina supported catalysts, catalyst intermediates, and methods of forming catalysts and microchannel apparatus
    Patent number: 8206597
    Abstract: The invention describes microchannel apparatus and catalysts that contain a layer of a metal aluminide or are made in a process in which a metal aluminide layer is formed as an intermediate. Certain processing conditions have surprisingly been found to result in superior coatings. The invention includes chemical processes conducted through apparatus described in the specification. Other catalysts and catalyst synthesis techniques are also described.

  • Chalcogenide glass nanostructures
    Patent number: 7211296
    Abstract: Chalcogenide nanowires and other micro-and nano scale structures are grown on a preselected portion of on a substrate. They are amorphous and of uniform composition and can be grown by a sublimation-condensation process onto the surface of an amorphous substrate. Among other uses, these structures can be used as coatings on optical fibers, as coatings on implants, as wispering galleries, in electrochemical devices, and in nanolasers.
