An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

There is provided an optical device for transferring light within a given field-of-view, comprising an input aperture; reflecting surfaces, and an output aperture located in spaced-apart relationship from the input aperture such that light waves, located within the field-of-view, that enter the optical device through the input aperture, exit the optical device through the output aperture, wherein the reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of the light waves located within the field-of-view that enter the input aperture, pass directly to the output aperture without being reflected off the at least one pair of parallel reflecting surfaces, while another part of the light waves within the field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by the at least one pair of parallel reflecting surfaces.

A system and process are disclosed for the controlled combustion of a wide variety of hydrocarbon feedstocks to produce thermal energy, liquid fuels, and other valuable products with little or no emissions. The hydrocarbon feeds, such as coal and biomass, are first gasified and then oxidized in a two-chamber system / process using pure oxygen rather than ambient air. A portion of the intermediate gases generated in the system / process are sent to a Fischer-Tropsch synthesis process for conversion into diesel fuel and other desired liquid hydrocarbons. The remaining intermediate gases are circulated and recycled through each of the gasification / oxidation chambers in order to maximize energy production. The energy produced through the system / process is used to generate steam and produce power through conventional steam turbine technology. In addition to the release of heat energy, the hydrocarbon fuels are oxidized to the pure product compounds of water and carbon dioxide, which are subsequently purified and marketed. The system / process minimizes environmental emissions.

A low power, lightweight, collapsible and rugged antenna positioner for use in communicating with geostationary, geosynchronous and low earth orbit satellite. By collapsing, invention may be easily carried or shipped in a compact container. May be used in remote locations with simple or automated setup and orientation. Azimuth is adjusted by rotating an antenna in relation to a positioner base and elevation is adjusted by rotating an elevation motor coupled with the antenna. Manual orientation of antenna for linear polarized satellites yields lower weight and power usage. Updates ephemeris or TLE data via satellite. Algorithms used for search including Clarke Belt fallback, transponder / beacon searching switch, azimuth priority searching and tracking including uneven re-peak scheduling yield lower power usage. Orientation aid via user interface allows for smaller azimuth motor, simplifies wiring and lowers weight. Tilt compensation, bump detection and failure contingency provide robustness.

A rotary electromechanical device includes a first motor including a first stator and a first rotor, a second motor including a second stator and a second rotor, and variable power supplies for driving the respective motors independently of each other, The motors are arranged in series along the axial direction of a rotary shaft. Magnetic poles of the same polarity of the rotors are located at uniform angular positions around the rotary shaft while magnetic poles of the stator of the motor and magnetic poles of the stator of the second motor are displaced from each other in the circumferential direction of the rotary shaft.

In a process for producing an aromatic carboxylic acid, it is a dehydrating process which can achieve compactification of a step for removing water from a mixture of acetic acid and water produced in the production process, and which can reduce the consumed energy. In a production process of an aromatic carboxylic acid having an oxidation reaction step for producing a slurry of an aromatic carboxylic acid by carrying out liquid-phase oxidation reaction of an alkyl aromatic compound with an oxygen-containing gas in a solvent containing acetic acid in the presence of an oxidation catalyst, at least a portion of a mixture containing acetic acid and water produced in the production steps is separated into a permeable gas mainly comprising water and nonpermeable substances mainly comprising acetic acid, using a separation membrane having water selectivity.

Embodiments of the portable antenna positioner described provide a lightweight, collapsible and rugged antenna positioner for use in receiving low earth orbit, geostationary and geosynchronous satellite transmissions. By collapsing the antenna positioner, it may be readily carried by one person or shipped in a compact container. The antenna positioner may be used in remote locations with simple or automated setup and orientation. In order to operate the apparatus, azimuth is adjusted by rotating an antenna in relation to a positioner base and elevation is adjusted by rotating an elevation motor coupled with the antenna. The apparatus may update ephemeris data via satellite, may comprise a built-in receiver and may couple with a second positioner base comprising cryptographic, router or power functionality. The apparatus may comprise storage devices such as a hard drive or flash disk for storing data to and from at least one satellite.

Methods and systems for monitoring electrolyte bath fluids are provided. The electrolyte bath fluids can be electroplating, electroless plating or etching solutions. The monitoring systems employ microfluidic devices, which have built in microfluidic channels and microfabricated thin-film electrodes. The devices are configured with fluid pumps to control the movement and mixing of test fluids through the microfluidic channels. The microfabricated thin-film electrodes are configured so that the plating or etching bath fluid composition can be characterized by electrochemical measurements. The monitoring methods and system provide faster measurement times, generate minimal waste, and occupy dramatically reduced physical space compared to conventional bath-monitor systems. The monitoring systems and method also provide low-cost system and methods for measuring or monitoring electroless plating bath rates.

A sequential color display system using a white light source to create a full color image projected onto an image plane. A dynamic filter, typically a series of moving dichroic filters, generates a series of primary colored light beams that are swept across the surface of a spatial light modulator. Typically all three primary colors are produced simultaneously by the dynamic filter. The illuminated portion of the dynamic filter is imaged onto the modulator and controller provides appropriate image data for each portion of the modulator in synchronization with the sweep of the primary color bands across the modulator surface. The primary color bands are modulated by the spatial light modulator and the modulated light is focused by lens onto the image plane. The viewer integrates the light arriving at each portion of the image plane over a frame period to provide the perception of a full-color image.
