Abstract: A data protection system selectively deletes data from an electronic device when the device is reported as lost or stolen, or when another data protection triggering event occurs. Different data files may, for example, be treated differently depending on when such files were created. For example, data files that were created while the computing device was known to be in the owner's possession may be deleted, while data files created after the electronic device left the owner's possession may be left intact (since they may have been created by an innocent user). Data files created between these two points in time may be quarantined so that they later be restored, if appropriate.

Abstract: A method and apparatus for working asphalt pavement, comprising one or both of a mechanical, hydraulic, electric, or pneumatic means for providing high-speed rotation; a rotary tool comprising a first end comprising a working surface and a second end adapted for connection to the means for providing high-speed rotation; and a screed, cooperatively arranged with the rotary tool, and comprising a working surface adjacent the working surface of the rotary tool, wherein the rotary tool is spun at high speed and applied to the asphalt pavement, frictionally heating the asphalt pavement to a temperature sufficient to work the pavement locally adjacent rotary tool and the screed. The screed and rotary tool comprising abrasion resistant materials selected from the group consisting of high-strength steel, hardened alloys, cemented metal carbide, polycrystalline diamond, and cubic boron nitride. The rotary tool and the screed apparatus may comprise a closed loop control system.

Abstract: The invention provides a high throughput, high purity, high yield system and method of isolating and purifying rebaudioside A (“Reb A”), with acceptable water solubility for all commercial uses, from commercially available Stevia rebaudiana starting material. The invention also provides a means of maximizing yields of 99+% purity Reb A based on the attributes of a given batch of Stevia starting material. The Reb A produced by the invention is water soluble, devoid of bitterness heretofore associated with rebaudioside sweeteners, non-caloric, and suitable for use as a reagent and as an ingredient in orally consumed products, e.g., as a sweetener, flavor enhancer, and flavor modifier.

Abstract: A lamp assembly for use in a pressure sensitive paint measuring system, such as for measuring pressure on a test air vehicle using pressure sensitive paint, is constructed and configured to provide (1) exceptional cooling for the various optical elements and the housing, (2) a combination of filters that minimizes heat load on the interference filter, yet provides a high beam intensity at the desired wavelength, (3) a mounting structure for the lamp assembly that allows the lamp assembly to be accurately aimed and positioned with little translation of the output aperture, and (4) easy access to the internal components, including the bulb-reflector assembly and optical elements.

Abstract: Methods and apparatus for the hydrometallurgical separation and recovery of biological nutrients, cadmium, lead, and gypsum from raw materials such as electric arc furnace flue dust. Biological nutrients, including zinc and iron, are selectively separated and recovered from raw materials, including metals and metal oxides, and are selectively and variably recombined, to achieve a biological nutrient product which a desired relative concentration of zinc and iron. The process is a closed system generating no solid waste, no liquid water or acid waste streams, and whereby gypsum, and substantially all hazardous wastes such as lead and cadmium, are separated and recovered from raw material for sale as commercial products.

Abstract: A manually operable unit having a single handle for driving, steering and tilting a boat propeller. The crank handle, when turned, drives the propeller through bevel gearing. A vertical sleeve surrounding a vertical drive shaft has an offset U-shaped portion terminating in a sleeve serving as a bearing for the crank handle. Pushing the crank handle against the bearing rotates the vertical sleeve which mounts the propeller, therefore steering the propeller. Pulling of the handle will tilt the vertical sleeve with respect to a mounting C-clamp to pivotally raise the propeller.
