  • Patent number: 7293400
    Abstract: A method of monitoring a physical parameter comprises receiving a sensor signal representative of an actual value from each of a plurality of sensors. The method further comprises calculating confidence value for each sensed value and a weighted average of actual values of the sensor signal by weighting each sensed value by the respective confidence value. The weighted average is used to determine a corresponding value of the sensed parameter.

  • Publication number: 20070179406
    Abstract: A lancing device integrated with a sensing strip and method of making and using the same are provided. A lance and analyte sensing strip are combined in a single, preferably disposable, device. In a preferred embodiment, a slot is provided in a support member so the lance can be engaged by a lance driver and driven into the skin producing a bodily fluid sample from a wound. The sensing area of the sensing strip is adjacent to the wound location reducing dexterity requirements for patients.

  • Patent number: 7060059
    Abstract: A closed loop therapy system for controlling a concentration of a substance, such as blood glucose concentration, in the body of a user. The system and method employ a sensor system that measures a glucose level in the body, a controller that uses the measured glucose levels to generate an output that can be used to automatically or manually control an intradermal insulin infusion system to set a constant or time-varying profile of target blood glucose concentrations in a user, and then infuse an appropriate amount of insulin into the body of the user so as to reach and maintain the target values of the blood glucose concentration.

  • Patent number: 6973791
    Abstract: Methods and apparatus for operating a gas turbine engine without sustained detrimental levels of dynamic pressure are provided. The engine includes a combustor. The method includes determining the combustor acoustic level amplitude, comparing the acoustic level to a predetermined upper acoustic limit, and adjusting a fuel flow distribution to the combustor using a closed loop controller to facilitate reducing the acoustic level to a predetermined lower acoustic limit that is less than the upper acoustic limit.

  • Publication number: 20050148003
    Abstract: The invention is directed to methods of correcting a luminescence value, and methods of determining a corrected analyte concentration, by use of a device capable of providing a signal when a binding protein binds to at least one analyte, and a thermometer. The invention is also directed to systems which include such a device, and a processor for correcting measured luminescence of a reporter group based on a measured temperature. The invention is further directed to apparatuses that include a memory for storing luminescence information and temperature information, and a processor for correcting luminescence information. The invention is further directed to computer programs for executing the methods of the invention, and machine-readable storage medium on which programs are recorded.

  • Publication number: 20050113658
    Abstract: A device for sensing analyte concentration, and in particular glucose concentration, in vivo or in vitro is disclosed. A sensing element is attached to the distal end of an optical conduit, and comprises at least one binding protein adapted to bind with at least one target analyte. The sensing element further comprises at least one reporter group that undergoes a luminescence change with changing analyte concentrations. Optionally, the optical conduit and sensing element may be housed within a cannulated bevel.

  • Patent number: 6736588
    Abstract: A mechanical system for handling large and thin glass plates of dimensions as much as 2 m by 2 m by 0.5 mm, such as used to manufacture LCD panels in LCD panel testers, provides for positioning of the repair and inspection equipment by using lightweight hollow chucklets in air-bearing and vacuum contact with the glass plate under test, balanced on a rail along the center of mass for translation without warping. The elimination of a heavy rigid platform results in significantly reduced hardware costs, flexibility in processing and improved positioning performance.

  • Publication number: 20030182469
    Abstract: A distributed computer system having a server and remote client for executing an application on the server. A remote-capable user interface toolkit resides on the server and has remote-capable components that correspond to components of a user interface toolkit which resides on the remote client. The remote-capable components are substantially the same as corresponding components of the user interface toolkit, and interact with the application according to the same application programming interface. However, when invoked by the application, the remote-capable components issue a message to the component on the remote client to perform the corresponding function on the client. A network communication protocol of sending messages between the remote-capable user interface toolkit on the server and the user interface toolkit on the client is thereby generated.

  • Patent number: 6457933
    Abstract: An orifice plate assembly for a gas turbine engine that facilitates extending a useful life of bearing assemblies within the gas turbine engine is described. Each orifice plate assembly is coupled in flow communication with an engine air source, and includes a first body portion and a second body portion. The first body portion includes a channel and a flow opening. The channel is sized to receive the second body portion, such that the second body portion may slide with respect to the first body portion. The orifice plate assembly is adjustable after engine shutdown to regulate bearing loading.

  • Patent number: 6412563
    Abstract: An artificial lift assembly is suspended from a string of conduit in a well inside a well casing. An encapsulation module is independently suspended from the conduit and encases the pump assembly with a jacket. A series of well fluid conditioning tools are mounted to the lower end of the jacket, including a tubular screen, a desander located behind the screen, a string of disposal conduit extending below the desander, and a nucleation device located above the desander. The entire weight of this fluid conditioning equipment is completely supported by the jacket and the conduit. The encapsulation module is completely sealed so that the well bore fluid is limited to entering the module and pump through the screen. The screen removes larger contaminants from the fluid such as rubber and trash. After the fluid passes through the screen, it enters the desander where solid matter such as sediment is removed from the fluid and eliminated through the disposal conduit.
