Title: Methods and apparatus for measuring flow velocity in a wellbore using nmr and applications using same
Inventor: SPEIER PETER
IPC: E21B47/06
Filed: 2002-09-09
Abstract: The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.

Title: Method for making a masa based dough for use in a single mold form fryer
Inventor: BHASKAR AJAY RAJESHWAR
IPC: A21D13/00
Filed: 2005-05-05
Abstract: A method of making a masa-based dough for use in a single mold form fryer. The invention is an improved process of making a buoyant, low density, low moisture content dough that is easily sheetable and results in a fried tortilla chip-like product with a similar texture of traditional tortilla chips. Starch is added to corn masa dough to help control moisture release during frying. The high shear mixing of the dough entrains air through nuclei formation making the dough more buoyant, and results in a smaller particle size of the dough increasing the uniformity of moisture distribution. The uniformity of moisture distribution provides more uniform buoyancy of the masa-based dough as it travels through a single mold form fryer.

Title: System and method for current-mode amplitude modulation
Inventor: PEHLKE DAVID R
IPC: H03F3/24
Filed: 2005-07-11
Abstract: An amplifier circuit includes a power amplifier biased for saturated mode operation, and a controllable current source to provide supply current to the power amplifier. The controllable current source effects desired amplitude modulation of the output signal from the power amplifier by modulating the supply current it provides responsive to an amplitude information signal. In one or more embodiments, the current source includes a circuit that is configured to adjust one or more transmitter operating parameters responsive to detecting changes in the effective DC resistance of the power amplifier.  For example, the circuit may generate a compensation signal that reduces the effective DC resistance responsive to detecting that the effective DC  resistance has undesirably increased. By way of non-limiting examples, such compensation may be effected by changing a current mirror, an amplifier-to-antenna impedance matching, an amplifier bias or device size, or imposing some form of transmit signal back-off.
