  • Publication number: 20240130029
    Abstract: A toroidally confined plasma vessel defines a magnetically confined (MC) plasma region that is substantially symmetric by rotation around a central axis and where particles traveling along magnetic fields substantially never strike a wall. A plurality of magnetic field coils provides at least one X-point and guides plasma particles from the magnetically confined plasma region to the divertor target. A total magnetic field strength (comprising all components of the magnetic field) at the divertor target differs substantially from a total magnetic field strength (comprising all components of the magnetic field) at a position of the X-point on a last closed flux surface nearest to it; and a current drive means is operative in the MC plasma, including in the region near the Last Closed Flux Surface.

  • Patent number: 8085508
    Abstract: A piezo in-tongue microactuator includes a suspension assembly with a flexure tongue. The tongue has two slots that accept piezo actuators. The tongue also has multiple hinge flexible elements that translate the extension and/or contraction of the piezo actuators into rotary motion of the recording head. This rotary motion is then used to precisely position the recording element over the desired track on the hard disk drive and permits higher track density to be achieved.

  • Patent number: 7384396
    Abstract: A system and method for extracting a biological fluid from an organism and continuously monitoring its characteristics. The system includes a tissue interface device suitable for positioning on or about the surface of the biological membrane of the organism and a monitor and control unit coupled to the tissue interface device. The tissue interface device includes a sensor positioned in a flow path of the fluid for continuously sensing a characteristic of the biological fluid as it flows out from the one or more artificial openings formed in the biological membrane. The sensor generates a sensor signal representative thereof. The monitor and control unit electrically or optically reads the sensor to obtain a measurement of a characteristic, such as concentration of a particular analyte, of the biological fluid on a continuous basis.

  • Patent number: 7158894
    Abstract: A data collection and management system is provided for monitoring the condition of fuel tanks and for determining for each tank a degradation profile which provides an estimate of useful tank life and a prediction of when the tank is likely to need replacement before failure. The system is especially useful for monitoring residential fuel tanks and is also applicable for commercial and other tanks which are in a location where a tank failure would be harmful and potentially hazardous. A primary benefit of the system is to allow fuel dealers to identify tanks that should be replaced before they actually fail. The system provides the dealer with information which is useful in monitoring and servicing the fuel tanks of the dealers' customers.

  • Patent number: 7037277
    Abstract: A fluid collection and sensor device for placement over at least one artificial opening made in a biological membrane for measuring a characteristic of a biological fluid collected from the tissue through the at least one artificial opening. The device comprises a sensor positioned in a flow path of the biological fluid for contacting a quantity of the biological fluid and generating an indication of a characteristic of the biological fluid. According to one aspect of the invention, a waste fluid storage element, such as a reservoir, is positioned in the device to collect the biological fluid after it has made contact with the sensor. According to another aspect of the invention, various surfaces of the fluid flow path of the fluid collection and sensor device are treated with an agent to limit or minimize clotting, aggregation or sepsis of the biological fluid, blockage or clogging of the flow path or degradation of the sensor.

  • Patent number: 6922578
    Abstract: An integrated device for poration of biological tissue, harvesting a biological fluid from the tissue, and analysis of the biological fluid. The device comprises a tissue-contacting layer having an electrically or optically heated probe to heat and conduct heat to the tissue to form at least one opening, such as a micropore to collect biological fluid from the opening, and a detecting layer responsive to the biological fluid to provide an indication of a characteristic of the biological fluid, such as the concentration of an analyte in interstitial fluid. In the embodiment in which, the probe comprises a photosensitizing assembly designed for the uniform application of a photosensitizing material, such as, for example, a dye or a pigment, to a tissue, e.g., the stratum comeum.

  • Patent number: 6861854
    Abstract: A test device and method for testing one of a disk drive microactuator and a disk drive sensor that includes two piezoelectric elements. The test device includes a signal generator, signal analyzer, and a user interface. The test device is operational to provide a reference signal (e.g. an electrical signal) to one of the piezoelectric elements in the microactuator and obtain a test measure from the other one of the piezoelectric elements. The test measure is then utilized to assess a performance parameter for the microactuator. The test measure is generated by the other one of the piezoelectric elements in response to the reference signal provided to the first one of the piezoelectric elements.
