Method and apparatus for acquisition of a spread-spectrum signal

Water caddy

A water caddy for capturing, containing, transporting, and emptying a fluid includes an open top fluid container pivotally attached to a cabinet set on wheels. The fluid container is pivotable between a fill position in which the container receives fluid through the open top and an empty position in which fluid is emptied from the container through the open top without having to lift any portion of the cabinet. A pneumatic actuator interconnecting the cabinet and fluid container assists the user in emptying the fluid container by urging the fluid container toward its empty position. The water caddy 10 may be dimensioned to enable a user to conveniently empty captured fluid directly into an existing floor toilet. One or more brakes are employed to inhibit inadvertent movement of the water caddy as it is being filled or emptied.

Method of and system for detecting availability of cdma service

A radiotelephone 121 employs a service detection circuit 125 comprising at least one chip-rate detector 109 that measures the energy of the autocorrelation of a received composite CDMA signal and employs a different time delay for each measurement of the energy. A threshold detection circuit 127 combines the measured energies and determines that service is available if the combined energies exceeds a threshold, and determines service is unavailable otherwise. The chip-rate detectors 109 can be coupled in parallel to provide simultaneous measurements of the energy of the autocorrelation of the received composite CDMA signal, or a single chip-rate detector 109 can serially measure the energy of the autocorrelation of the received composite CDMA signal.

Process for producing methacrylic acid

In the vapor phase oxidation of methacrolein to methacrylic acid with molecular oxygen over a catalyst containing Mo, P, Cu, Sb, and Cs and/or Ca, the amount of methacrylic acid produced per unit weight of catalyst is improved by carrying out the oxidation in the presence of a greater molar ration of CO2/CO than is produced by the oxidation. When unreacted gases are recycled, the ratio of carbon dioxide to carbon monoxide can be increased by selective oxidation of the CO to CO2.

Safe cutter

The Safe Cutter, hereafter, “Cutter” is a device that cuts hot dogs into horizontal and vertical slices. The Cutter is designed to cut the hot dog into specified increments reducing the shape, size and diameter of the hot dog. This methodology of cutting a hot dog will prevent individuals, especially children, from choking on a hot dog based on its size and shape. The Cutter is composed of one horizontal blade and several vertical blades that are attached. In addition, the Cutter has a sleeve that holds the hot dog to be cut. Finally, the Cutter has a handle and a sleeve to cover the blades when not in use. Once the hot dog is cooked, one hot dog is placed in the Cutter's sleeve then with a downward motion the Cutter cuts the hot dog into a horizontal slice and vertical slices. There is no device on the market today that is specifically designed to cut a hot dog into horizontal and vertical slices. This is not just another invention, this is a device that will save lives by reducing, if not eliminating individuals and especially children from choking on a hot dog based on its shape and size.

Delayed coking process with water and hydrogen donors

A residual oil feedstock comprises carbon residue measured according to ASTM D-4530. The feedstock is admixed with water/steam in an amount of 10 wt% to 30 wt% and optionally a hydrogen donor, such as methane and/or gas oil derived from recycle. The resulting admixture is subjected to delayed coking reaction conditions. The process yields hydrocarbon liquids in an increased amount. Coke make and gas make are thereby reduced.

Genetically engineered recombinant proteins for functional regenerative tissue scaffolds

Protein complexes are profound in various biological processes, and their ability to self-associate offers exciting opportunities for innovative biomaterials. However, the weak physical interactions within protein complexes result in limited mechanical stability and fast erosion rates, posing a significant challenge. Thus, a SAv-based hydrogel where SAv tetramers serve as crosslinking junctions is described herein. These mechanically reinforced SAv tetramers significantly enhanced the shear elasticity and decelerated the bioerosion process of the overall material. This simple approach to modulate the mechanical strength of protein complexes as crosslinking junctions present an attractive prospect for a myriad of biotechnological applications, such as biomimetic scaffolds and soft robotics.
