A sheath constructed of a flexible material is deployable around the rigid member of the tool to produce a rigidly supported soft and smooth surface for honing blades.

Abstract: According to one example, a system includes a first computing device that determines data for transmittal to a second computing device, and determines transmittal mapping data. The first computing device also breaks the data into one or more portions, and, for each of the one or more portions of the data, the first computing device replaces the respective portion of the data with a transmittal token included in the transmittal mapping data. The first computing device also transmits the transmittal tokens for receipt by the second computing device.

In response to a determination that the first computing device passed the one or more tests, the first computing device manipulates an authentication code to generate a first seed value. In response to a determination that the first computing device failed the one or more tests, the first computing device manipulates the authentication code to generate a second seed value. The first computing device also determine data for transmittal to a second computing device, modifies the data using the first seed value or the second seed value, and transmits the modified data for receipt by the second computing device.

Abstract: According to one example, a system includes a second computing device that receives encrypted data from a first computing device. The encrypted data is encrypted based on a first encryption key. Also, the data is obfuscated prior to encryption. The second computing device generates a second encryption key that matches the first encryption key, decrypts the encrypted data using the second encryption key, un-obfuscates the data, and transmits the data for use.

Abstract: Surveillance systems of this invention incorporate a charge coupled device image sensor with an illumination source that is made of an emitter which concentrates its optical output in a narrow band at or about the peak optical response of the photoconverter being used. Where a silicon imaging sensor is being used, the illumination system can comprise an emitter made of a rare earth oxide, such as ytterbium oxide, in the form of a filamentary network and fuel to energize the emitter. Different emitters can be employed to achieve the optimal radiant energy for any type of photoconverter device, including those based on silicon, germanium, indium gallium arsenide, and gallium antimonide. These surveillance systems may be applied in a number of specialized applications, such as, for example, in the covert surveillance of commercial, industrial, residential, or military sites, or any site in which the visible illumination of the surveillance area is undesirable.

Abstract: Portable, small, and light-weight radiant and/or electrical power generating sources, constructed according to the principles of this invention, comprise an air/fuel delivery device that houses a fuel canister of pressurized hydrocarbon fuel therein. The fuel canister includes a check valve that is selectively activated to release the pressurized hydrocarbon fuel to a pressure regulator and then through a venturi disposed within the delivery device. The delivery device includes an ignitor that is also activated when the fuel is released. A radiant head is attached to the delivery device and includes a luminous mantle in gas flow communication with the venturi and formed from a fibrous rare earth oxide. The head includes a lens and reflector system adjacent the mantle. Alternatively, or in addition to the radiant head, a thermophotovoltaic head can be attached to the delivery system.

Abstract: An electrically driven metering pump removes used oil in precise increments at a controllable rate of repetition from a safe operating level in the sump or reservoir of an engine, compressor, transmission or other power equipment; preferably in combination with means provided by a circulating oil supply system, in which withdrawal of oil from the sump is at a controlled running level and oil for removal is taken from a withdrawal path in the supply system, using a separator to exclude air from the oil removed. Oil removed by the metering pump is filtered and delivered to an electrically driven blending pump, which draws in engine fuel for combination with this oil by turbulence, repetitive transfer, heating and forced dispersion to produce a primary blend at a composition determined by the relative volumes of delivery per operating pulse and the relative rates of pulse repetition of the metering and blending pumps.
