    摘要： A processing technique for creating nanowires and hierarchically porous micro/nano structures of ceramic materials is provided. The process includes evaporation of micron-sized water droplets containing dissolved organic salts on heated substrates followed by thermal decomposition of the deposited material. The micron-sized droplets may be generated by supercritical CO2 assisted nebulization, in which high-pressure streams of aqueous solution and supercritical CO2 are mixed, followed by controlled depressurization through a fine capillary. Rapid evaporation takes place on the heated substrates and structures are generated due to CO2 effervescence from the droplets and evaporation of water, along with the pinning of the three phase contact line. Depending on the mass deposited, a mesh of nano-wires or membrane-like structures may result. Sintering of the membrane-like scaffolds above the decomposition temperature of the organic salt creates nanopores within the structures, creating a dual hierarchy of pores.

    摘要： A blind aid device designed for non-verbal communication between a blind person and a companion includes a body-worn sensor system to be worn by the companion, a body-worn actuation system to be worn by the blind person and a wireless communication link between the body-worn sensor system and the wearable body-worn actuation system. The body-worn sensor system includes a gyroscope configured to detect and record a velocity of tilting and turning head movements of the companion, an accelerometer configured to detect and record an extent of the tilting head movements of the companion, and a magnetic compass sensor configured to detect and record an extent of the turning head movement of the companion. The wearable body-worn actuation system includes an array of control electronics and actuators configured to translate electronic signals transmitted from the body-worn sensor system into physical movements, in real time.

    摘要： Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for capturing, using a camera, an image of a general writing surface. The captured image is compared with one or more previously saved images. A related image is determined based upon syntax and semantics of handwriting recognized in the captured image and the one or more previously saved images. A previous document associated with the related image is retrieved and set as the active document. A position of a writing instrument is mapped to a position within the previous document.

    摘要： An improved processing technique that can be used to collect nanoparticles produced by the RESS process. The collection efficiency by almost an order of magnitude compared to the traditional collection processes. One process does not utilize any stabilizing solid co-solvents but produces similar effects using the supercritical solvent itself (e.g. CO2) as a stabilizing phase. Very small particles (diameter
