Publication number: 20090121792Abstract: 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.Type: ApplicationFiled: January 12, 2009Publication date: May 14, 2009Inventor: Christopher Julian Travis

Publication number: 20080209094Abstract: 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.Type: ApplicationFiled: May 17, 2007Publication date: August 28, 2008Inventor: Christopher Julian Travis

Publication number: 20070208223Abstract: 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.Type: ApplicationFiled: March 21, 2007Publication date: September 6, 2007Applicant: Intuitive Surgical, Inc.Inventors: Christopher Julian, Michael Ikeda, Andris Ramans, Dean Hoornaert, Margaret Isaac
