  • Patent number: 9283348
    Abstract: 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.

  • Publication number: 20130142913
    Abstract: 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.

  • Patent number: 6958604
    Abstract: A method for obtaining nuclear magnetic resonance measurements includes inducing a static magnetic field in a formation fluid sample; applying an oscillating magnetic field to the fluid sample according to a preparation pulse sequence that comprises a J-edit pulse sequence for developing J modulation; and acquiring the nuclear magnetic resonance measurements using a detection sequence, wherein the detection sequence comprises at least one 180-degree pulse. The method may further include acquiring the nuclear magnetic resonance measurements a plurality of times each with a different value in a variable delay in the J-edit pulse sequence; and analyzing amplitudes of the plurality of nuclear magnetic resonance measurements as a function of the variable delay to provide J coupling information.

  • Patent number: 6091243
    Abstract: 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.

  • Patent number: 5994902
    Abstract: 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.
