Publication number: 20130263201Abstract: This invention relates to a method and system of transmitting video data and multimedia data to a plurality of client radio receivers over an air interface using an adaptive encoding/transcoding scheme and updating the adaptive encoding/transcoding scheme in dependence upon received feedback data. A system and method is also described that includes estimating channel states and distortion levels for a plurality of transmission modes, then selecting that transmission mode for subsequent data transmission that has the lowest distortion level. Control data items can also be extracted from the first data stream to produce a multimedia data stream and a control data stream and the multimedia data stream is transmitted over a first channel; and the control data stream is transmitted over a second channel.Type: ApplicationFiled: June 1, 2011Publication date: October 3, 2013Applicant: GI PROVISION LIMITEDInventors: James Chung-How, Andrew Nix, David Bull

Publication number: 20130123624Abstract: A biologic ventricular assist device that also has the capability to capture, grow, and administer stem cells to regenerate and restore damaged myocardium in the heart. The device works in conjunction with a traditional ventricular assist device and possesses an additional external path or tube that is in-line with the path of the ventricular assist device. The external path allows for the administration of stem cells, genes, genetically modified cells or other therapeutic biologic or pharmacologic agents, as well as leading to a stem cell collecting accessory that captures circulating stem cells. The stem cell collecting accessory is also associated with a chamber for culturing the captured stem cells.Type: ApplicationFiled: June 14, 2012Publication date: May 16, 2013Applicant: UNIVERSITY OF UTAH FOUNDATIONInventors: David A. Bull, Rafe C. Connors, Harold M. Erickson, James Yockman, Sung Wan Kim

Patent number: 8153155Abstract: An arginine-grafted bioreducible poly(disulfide amine) (“ABP”) as a reagent for efficient and nontoxic gene delivery is described. ABP forms positively charged nano-particles of less than 200 nm with siRNA. ABP is biodegraded under reducing conditions, such as in the cytoplasm. ABP exhibits much higher transfection efficiency than polyethyleneimine in mammalian cells and exhibits no cytotoxicity. ABP is an effective delivery vehicle for gene silencing with siRNA and may be used for treating cancer.Type: GrantFiled: July 1, 2009Date of Patent: April 10, 2012Assignee: University of UtahInventors: Sun Hwa Kim, Ji Hoon Jeong, Tae-il Kim, Sung Wan Kim, David A.

Publication number: 20080245362Abstract: The present invention relates to a nebuliser and method of nebulising a liquid. The nebuliser includes a nebulisation chamber (1) having a well (2) adapted to contain a liquid (3) to be nebulised. An energy source in the form of an ultrasonic transducer (6) has as a curved energy transmission surface (7). This curved energy transmission surface defines a focal point (8) and a focal length (9). The energy source is spaced from the well such that the distance between the focal point and the energy source intrudes into the well not greater than 50% of the focal length. Preferably the well is shaped such that during nebulisation the level of the liquid in the well remains within a predetermined focal length range to thereby provide a substantially constant flowrateut of nebulised liquid. The nebuliser may also include a deflector baffle or fountain diverter (16) which acts to deflect the nebulised liquid fountain rising from the well.Type: ApplicationFiled: September 6, 2006Publication date: October 9, 2008Inventors: George Moessis, Jack Vaisman, Philip Jenkinson, David Bull, Andy Wyatt

Publication number: 20070162798Abstract: An integrated circuit 2 includes logic circuitry 10 and sequential storage elements 8. Both the logic circuit 10 and sequential storage elements 8 can be subject to particle strikes giving rise to single event upset errors. These single event upset errors can be detected by detecting a transition in the stored value stored by the sequential storage elements 8 occurring outside of a valid transition period associated with that sequential storage element 8.Type: ApplicationFiled: December 11, 2006Publication date: July 12, 2007Applicants: ARM Limited, Regents of the University of MichiganInventors: Shidhartha Das, David Blaauw, David Bull
