Inventor: PRATT DAN W
IPC: E21B29/02
Filed: 2009-01-21
Abstract: A method for perforating a subterranean formation includes positioning a shaped charge and a reactant composite material in a carrier; positioning the carrier in the wellbore; detonating the shaped charge; and disintegrating the reactant composite material using a shock generated by the detonated shaped charge. The method may also include initiating a first deflagration by using carbon and heat resulting from the detonation of the shaped charge and an oxygen component of the disintegrated reactant composite material.  A system for performing the method may include a carrier, a shaped charge positioned in the carrier; and a reactant composite material positioned in the carrier. The reactant composite material may be configured to disintegrate upon detonation of the shaped charge.

Abstract: A sensing device for use with a method and structure for heat transport, cooling, sensing and power generation is described. Photonic bandgap structures are employed to enhance emissive heat transport from heat sources such as integrated circuits. The photonic bandgap structures are also employed to convert heat to electric power by enhanced emission absorption, cool and sense radiation, such as infra-red radiation. The concepts may be applied to both heat loss and heat absorption, and may be applied to heat transport and absorption enhancement in a single device.

IPC: A23L19/12
Filed: 2009-06-11
Abstract: A method for reducing the amount of acrylamide in thermally processed foods. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on the manipulation of various unit operations used in the production of food products, particularly the peeling, cooking, and rejecting unit operations.  For example, the peeling unit operation can be modified to provide a more fully peeled potato slice. The cooking unit operation can be modified by cooking to higher moisture and/or at lower hot oil temperatures to minimize the high-temperature / low-moisture conditions most favorable for acrylamide formation. The rejection unit operation can be modified to reject, defects that result in high levels of acrylamide.

Abstract: By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.
