摘要： A method and apparatus to create two dimensional and three dimensional structures using a maskless photolithography system that is semi-automated, directly reconfigurable, and does not require masks, templates or stencils to create each of the planes or layers on a multi layer two-dimensional or three dimensional structure. In an embodiment, the pattern generator comprises a micromirror array wherein the positioning of the mirrors in the micromirror array and the time duration of exposure can be modulated to produce gray scale patterns to photoform layers of continuously variable thickness. The desired pattern can be designed and stored using conventional computer aided drawing techniques and can be used to control the positioning of the individual mirrors in the micromirror array to reflect the corresponding desired pattern. A fixture for mounting of the substrate can be incorporated and can allow the substrate to be moved three dimensions. The fixture can be rotated in one, two, or three directions.

摘要： A gyroscope (10) for determining rate of rotation includes a giant magnetoresistor (GMR) (14) attached to a mass (12) oscillating along a first axis. When the gyroscope (10) is rotated, the mass (12) also oscillates along a second axis perpendicular to the first axis. A magnetic element (16), which includes of a strip of magnetic bits (18), is disposed along the first axis, the second axis, or both. The magnetic bits (18) supply discrete magnetic fields. The GMR (14) changes in electrical resistance when exposed to these magnetic fields. A voltage sensor (20) and processor (34) are then utilized to calculate the rate of rotation.

摘要： Analysis of complex media (e.g.—blood and seawater) is difficult because the media are composed of particles of different sizes and chemical profiles. Disclosed is a method for the detection of a constituent in a medium that enhances the molecular selectivity of a detector by separating the detector from the medium by a membrane of specified permeability. Proxy reporters are employed to enhance particle specificity. The novel combination of the invention has application to chemical detection in a broad range of fields.

摘要： A portable pressure-driven fluid pump and integrated power supply that relies on high pressure without the use of stored high pressure gases or liquids. A material transitions through a phase change in a constant volume container so that the pressure in the container increases. Programmability and sequential actuation are enabled by patterning the phase change material into the integrated device. The pressure generated may be used to activate an energy transducer such as a high pressure turbine, a piezoelectric material, and an elastic strain material. This provides a hybrid actuation system of electrical energy, pneumatic and hydraulic power. The pressure change in a constant volume container is also harnessed to provide a microbattery.

摘要： A method for making a patterned SiO2 films over TiO2 (SiO2/TiO2) under ambient atmospheric conditions, including room temperature, through photo and chemical reactions. The method is simple, convenient and can be performed in a short period of time, typically less than two hours. The patterned TiO2 film is fabricated through photo-irradiation of a photosensitive organic-titanium film using a mask. Silica particles are generated from silicate solution by adjusting pH values to 10 to 8 with hydrochloric acid. The pre-deposited TiO2 film has a strong attraction for the SiO2 particles, leading to the instant formation of SiO2 film over the TiO2 film. The silica films are also amino-silylated with 3-aminopropyltriethoxysilane toward applications such as patternable, location-specific silica-based separation and purification.
