  • Publication number: 20090121792
    Abstract: A hybrid numeric-analog clock synchronizer, for establishing a clock or carrier locked to a timing reference. The clock may include a framing component. The reference may have a low update rate. The synchronizer achieves high jitter rejection, low phase noise and wide frequency range. It can be integrated on chip. It may comprise a numeric time-locked loop (TLL) with an analog phase-locked loop (PLL). Moreover a high-performance number-controlled oscillator (NCO), for creating an event clock from a master clock according to a period control signal. It processes edge times rather than period values, allowing direct control of the spectrum and peak amplitude of the justification jitter. Moreover a combined clock-and-frame asynchrony detector, for measuring the phase or time offset between composite signals. It responds e.g. to event clocks and frame syncs, enabling frame locking with loop bandwidths greater than the frame rate.

  • Publication number: 20090004479
    Abstract: A coated veneered article has at least one visible wood veneer layer coated with a multilayer finishing system comprising a coating layer nearest the veneer layer comprising a cationically polymerized moiety or moiety polymerized via cationic and free radical cure mechanisms, and an outermost coating layer comprising a free radically polymerized moiety. The article exhibits less veneer checking than a veneered article coated only with free radically polymerized coating layers.

  • Publication number: 20080209094
    Abstract: A communications bus operates using transition coding, for example NRZI coding, with transition-dominant signalling. That is, when the signal takes a first binary value, binary “1”, the component drives the bus line to its opposite state, and, when the signal takes a second binary value, binary “0”, the component does not actively drive the bus line. During arbitration, each arbitrating component writes a unique arbitrand onto the bus, and arbitration is lost by each component that writes a binary “0” when at least one other component writes a binary “1”. The components preferably do not use transition-dominant signalling when transmitting data payloads. For such traffic they actively drive the binary “0”s as well as binary “1”s.

  • Publication number: 20080205453
    Abstract: On a communications bus, a relatively low frequency timing reference is distributed by regularly transmitting numbers that represent its instantaneous phase. An active framer component maintains a wrapping count of root superframes and, during each block, transmits in encoded form an expected value for the root superframe count at the start of the following block.

  • Publication number: 20080091079
    Abstract: A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

  • Publication number: 20070233161
    Abstract: Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position relative to one another, and the cartridge member is re-loadable with a removable staple cartridge to form multiple plications within the organ with the same tissue treatment device.

  • Publication number: 20070208223
    Abstract: Devices, systems and methods related to endoscopic surgery, particularly related to robotic surgical operations, provide a tissue stabilizer for endoscopically stabilizing a target tissue within a patent's body. For stabilizing a beating heart during a closed-chest coronary artery bypass grafting procedure, a stabilizer is inserted through an endoscopic cannula and provides sufficient surface area to contact the heart and effectively stabilize the target tissue area. The stabilizer can straddle a blood vessel, such as a coronary artery, which is targeted for an anastomosis. Vessel occlusion fasteners may occlude the target blood vessel prior to the anastomosis procedure.

  • Publication number: 20070093792
    Abstract: Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. Examples of in vivo accessories include fastening accessories such as surgical clips for use with a clip applier, single working member accessories such as a blade which can be grasped and manipulated by a grasping tool for cutting, sheath accessories that fit over working members of a tool, flow tubes for providing suction or introducing a fluid into the surgical site, and a retraction member resiliently biased to retract a tissue to expose an area in the surgical site for treatment. The accessories can be introduced into the surgical site by a dedicated accessory introducer, or can be supported on the body of a surgical tool inserted into the surgical site and be manipulated using another surgical tool in the surgical site.
