  • Patent number: 8337380
    Abstract: An apparatus for separating at least two discrete volumes of a composite liquid into at least a first component and a second component, comprising a valve design that facilitates loading and unloading of blood bags and associated tubing and bag sets. The valves comprise a rotating head, mounted on a shaft, which assumes a “load” position. The head pivots to an “open” position, which secures the tube in its designated location, but which maintains an open lumen through the tube. When the head is in a “closed” position, blood components cannot flow through the tube. The valve apparatus comprises means for maintaining a constant pressure on the tube and contact with the tube as the tube is melted and sealed.

  • Publication number: 20120296358
    Abstract: A coring knife can be used to make a circular incision. The coring knife includes an abutment that is inserted into an initial slit through the heart wall. The abutment can be inserted into the slit while oriented in a direction that minimizes its insertion profile. After insertion, the abutment is reoriented by turning a key so that its abutment surface faces toward a circular cutting edge of the coring knife on the other side of the heart wall. The circular incision through the heart wall is made by pressing the circular cutting edge of the coring knife against the abutment.

  • Publication number: 20120010455
    Abstract: Preparing the heart for connection with a ventricular assist device (VAD) can include attaching an attachment ring to a ventricular apex of the heart. The attachment ring optionally includes a seal or a valve to allow the procedure to be performed with or without a heart-lung bypass. A valve can be temporarily attached to the attachment ring. Tissue is removed from the ventricular apex through the attachment ring to form a hole through which an inflow conduit of the VAD can be inserted. A slit can first be made in the ventricular apex to facilitate removal of the tissue. A clamp can be closed around the attachment ring to secure the inflow conduit.

  • Publication number: 20110260055
    Abstract: The present invention generally relates to dynamic focus adjustment for an image system. With the assistance of a height detection sub-system, present invention provides an apparatus and methods for micro adjusting an image focusing according the specimen surface height variation by altering the field strength of an electrostatic lens between objective lens and sample stage/or a bias voltage applied to the sample surface. Merely by way of example, the invention has been applied to a scanning electron inspection system. But it would be recognized that the invention could apply to other system using charged particle beam as observation tool with a height detection apparatus.

  • Publication number: 20110254776
    Abstract: An improved portable electronic device includes a touch-sensitive display and a text input routine that employs an error correction routine. The error correction routine evaluates inputs to determine whether they are ambiguous based upon the actual location of the input and with the use of a linguistic database. The error correction routine is suspended for a single input immediately following a deletion input, after which the error correction routine is automatically reactivated. In the example embodiment described herein, the error correction routine is suspended for a single input by ignoring the output of the error correction routine, after which the output of the error correction routine is not ignored for subsequent inputs.

  • Patent number: 7978017
    Abstract: Exemplary embodiments of the invention provide a reference signal generator, system and method. An exemplary apparatus to generate a harmonic reference signal includes a reference resonator, such as an LC-tank, a control voltage generator adapted to provide a temperature-dependent control voltage; and a plurality of variable reactance modules. The reference resonator generates a first reference signal having a resonant frequency, and each reactance module is adapted to modify a corresponding reactance in response to the control voltage to maintain the resonant frequency substantially constant or within a predetermined variance over a predetermined temperature range. A frequency controller may also be included to maintain substantially constant a magnitude of a peak amplitude of the first reference signal and maintains substantially constant a common mode voltage level of the reference resonator.
