Patent number: 7641524Abstract: A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle.Type: GrantFiled: April 11, 2008Date of Patent: January 5, 2010Assignee: Liquid Robotics Inc.Inventors: Roger G.

Publication number: 20070166170Abstract: Apparatuses and methods for pumping fluid are disclosed. An exemplary apparatus is a miniature pump that includes a shape memory wire that obtains a plastic condition below a transformation temperature and has a memorized shape such that the shape memory wire produces a work stroke by returning to the memorize shape at least at the transformation temperature. A spring biased against the shape memory wire is deflected by the work stroke to deform the shape memory wire from the memorized shape below the transformation temperature. A fluid pump is coupled to the shape memory wire and driven by the biased spring and shape memory wire to produce a fluid flow. The miniature pump can be incorporated into a self-contained infusion device in the form of a compact self-adhesive patch including a fluid reservoir, control electronics and power supply that is place directly at the infusion site of a user.Type: ApplicationFiled: March 21, 2007Publication date: July 19, 2007Applicant: Medtronic MiniMed, Inc.Inventors: Clyde Nason, William Stutz, Darren Yap

Publication number: 20070100283Abstract: An external infusion device that infuses a fluid into an individual's body includes a housing, a reservoir, a drive system, a power supply, electrical elements, and a tab. The reservoir contains the fluid, and the drive system forces the fluid from the reservoir. The electrical elements control the power to the drive system to regulate the rate that fluid is forced from the reservoir. The tab mates with the housing, and contains at least one electrical element. The tab is removable, and may be replaced with a different tab. The different tab may change the rate fluid is forced from the reservoir. A tab may be removed from one external infusion device and installed in a different external infusion device. The tab may be limited to use in a predetermined number of external infusion devices and may include a power supply.Type: ApplicationFiled: November 6, 2006Publication date: May 3, 2007Inventors: James Causey, William Stutz, Clyde Nason, Sheldon Moberg, Jay Yonemoto, Richard Purvis, Cary Talbot

Publication number: 20060044474Abstract: Digital dc restore methods and apparatus to restore the DC component of an analog waveform to a quantized reference value level at a given temporal point on a waveform, prior to an ADC. This may used to establish the relationship between the full scale digital value out of the ADC and the waveform being digitized. For a video signal, the Digital Value of Black, is compared with the value on the back porch of the video signal. The difference is converted to the analog domain by a DAC clocked at the Temporal Point to provide a sample and hold function. An amplifier compares the difference, mapped to one half full scale digital, to an analog common mode voltage for the ADC, removing any error due to the difference between them. Other applications include correlated double sampling of contact image sensors to remove Dark Current Offset.Type: ApplicationFiled: September 1, 2004Publication date: March 2, 2006Inventor: William Stutz

Publication number: 20050198393Abstract: Methods and apparatus for arbitrarily extendible information aggregation and display. This functionality is achieved by abstracting the components of the system into individual modules which communicate using a platform-independent, extendible markup language such as extensible markup language (XML). A designer adds support for new information sources or client devices by abstracting and encapsulating messages to and from the information source or client device in a wrapper using a platform-independent, extendible markup language such as XML.Type: ApplicationFiled: January 7, 2005Publication date: September 8, 2005Applicant: CITRIX SYSTEMS, INC.Inventors: William Stutz, Arulnambi Kaliappan, Ronald Capwell, Paul Martin, Todd Ogrin

Patent number: 6368067Abstract: The fluid pump of the present invention includes an upper enclosure for holding fluid (typically a liquid) from a fluid input source, and a lower enclosure for outputting the fluid to an output line. A first valve (a) controls the fluid input flow into the upper enclosure. A second valve (b) is engaged in a line between the upper enclosure and the lower enclosure to control the fluid flow from the upper enclosure to the lower enclosure. A second fluid input line is engaged to the lower enclosure to input a second fluid (typically a pressurized gas) into the lower enclosure, and a third valve (d) is engaged in a line between the lower enclosure and upper enclosure to control the flow of the second fluid into the second enclosure. A fourth valve (c) is engaged in a fluid output line to control the flow of the second fluid out of the upper enclosure. In the preferred embodiments, each of valves a, b, c and d is controlled by an automated pump system controller.Type: GrantFiled: August 22, 2000Date of Patent: April 9, 2002Assignee: Chemand CorporationInventor: William A.

Patent number: 5650736Abstract: A technique for high speed transmission of digital signals on a bus line with reduced signal ringing, bounce and bus contention current. The approach uses a multi-partitioned driver design with temporary and steady state parts incorporating internal feedback and delay techniques to control the output slew rate. A built-in function outputs the driving status of the transceiver and allows the output to enter the high impedance status asynchronously.Type: GrantFiled: June 6, 1995Date of Patent: July 22, 1997Assignee: Advanced Micro Devices, Inc.Inventors: Philip Y. Pun, William A. Stutz

Patent number: 5583806Abstract: Carry-save adder techniques are used to concurrently generate Effective and Intermediate (also known as Relocation or Linear) Addresses with only a single carry propagation for each Address. Base, Scaled Index, and Displacement components are input to a first carry-save adder, which is common to both address calculations. A first sum vector and a first left-shifted carry vector are inputs to a first carry-propagate adder for generating the Effective Address. A second carry-save adder has as inputs a Segment Base Address, said first sum vector, and said first left-shifted carry vector. A second sum vector and a second left-shifted carry vector are inputs to a second carry-propagate adder for generating the Intermediate Address.Type: GrantFiled: March 10, 1995Date of Patent: December 10, 1996Assignee: Advanced Micro Devices, Inc.Inventors: Larry Widigen, William A.
