Patent number: 9283348Abstract: In various embodiments, an electronic flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. When the system is in a manual mode, backup manual flow selectors may be used to directly control the flow rate of a fluid. When the system is in a manual mode, the mechanical backup flow selectors may be in a deployed position. When the system is in an electronic mode, the mechanical backup flow selectors may be in a retracted position. Particular applications to gases and anesthesia delivery are disclosed herein.Type: GrantFiled: November 18, 2014Date of Patent: March 15, 2016Assignee: SHENZHEN MINDRAY BIO-MEDICAL ELECTRONICS CO., LTDInventors: Peter B.

Publication number: 20130142913Abstract: A food product having a pre-cooked loose meat filling along with a seasoning mix is provided in an edible casing. The edible casing is filled with the pre-cooked loose meat filling and the seasoning mix to produce a filled casing that is subsequently cooked to produce a meat link. The food product also may have a raw meat batter that is combined with the pre-cooked loose meat filling and filled into the edible casing along with the pre-cooked loose meat filling prior to subsequent cooking of the meat link. The pre-cooked loose meat filling may include discrete, not fully ground meat material including meat finely chopped, diced, chunks, shred, and splinters of meat. Alternatively, the pre-cooked loose meat filling may include cooked ground meat, though the pre-cooked loose meat filling will still have individual pieces larger than an emulsified product.Type: ApplicationFiled: December 6, 2011Publication date: June 6, 2013Inventors: Kyle B.

Patent number: 6091243Abstract: A method acquires three complex images, wherein their respective phase differences between water and fat components are .alpha..sub.0, .alpha..sub.0 +.alpha., and .alpha..sub.0 +2.alpha., respectively. The method obtains from these three complex images two possible solution sets for water and fat images. For pixels with both water and fat components, one correct solution set is selected using a binary choice based on the relative Larmor frequencies of water and fat. If a pixel contains only one component, a known statistical bias is applied to identify the component and, thus, the pixel. To correct misidentified pixels, various filters may be applied to all the pixels. The water and fat solutions obtained from the three complex images are used to produce separate images of water and fat. Second pass solutions of water and fat with improved signal-to-noise ratio can be obtained by either averaging or a least square error method.Type: GrantFiled: November 13, 1998Date of Patent: July 18, 2000Assignee: The University of British ColumbiaInventors: Qing-San Xiang, Li An

Patent number: 5994902Abstract: Chemical shift imaging with spectrum modeling (CSISM) models the general chemical shift spectrum as a system with N distinct peaks with known resonant frequencies and unknown amplitudes. Based on the N peak spectrum model, a set of nonlinear complex equations is set up that contains N+1 unknowns of two kdnds: the magnitudes of the N peaks, and a phasor map caused by main magnetic field inhomogeneity. Using these equations, the timing parameters for shifting the 180.degree. RF refocusing pulses for acquiring spin-echo images are optimally chosen. Corresponding timing parameters for other pulse sequences can also be optimized similarly. Using the chosen timing parameters, a plurality of images are acquired. Next, acquired image data are automatically processed to solve the complex linear equations. First, the phasor map is found by fitting various phasor map values over a small number of pixels, or "seeds", that are picked sparsely in a field of view.Type: GrantFiled: April 9, 1998Date of Patent: November 30, 1999Assignee: The University of British ColumbiaInventors: Qing-San Xiang, Li An
