摘要： A damper for downhole tools consisting of a plurality of damping inserts arrayed about the tool body so that their radial protrusion describes a circumference greater than desired gauge of the borehole. The damper inserts are configured with rounded working surfaces that radially protrude from the tool body and are coated with an abrasion resistant, superhard material. The damper inserts are progressively arrayed so that they are constantly forced against the walls of the borehole. In this manner, they may plastically fail the formation by an indenting, brinelling, or crushing action that produces a constant torsional load on the downhole tools, and controls the torsional unloading of the downhole tools and absorbs the vibrations of the drilling tool as the formation is being drilled.

摘要： An annular wire harness for use in drill pipe comprising two rings interconnected by one or more insulated conductors. The rings are positioned within annular grooves located within the tool joints and the conductors are fixed within grooves along the bore wall of the pipe. The rings may be recessed within annular grooves in order to permit refacing of the tool joint. The rings are provided with means for coupling a power and data signal from an adjacent pipe to the conductors in such a fashion that the signal may be transmitted along the drill pipe and along an entire drill string.

摘要： The toilet bowl separately collects urine and feces for analysis or use in a composting device, waste digester, or to reclaim water. The toilet bowl includes a toilet bowl wall. Urine flows down the toilet bowl wall into a channel for collection. The channel surrounds an aperture into which feces may be deposited. Consequently, urine and feces are kept separate during collection. Both the channel and the aperture may be connected to conduits which may transmit material into analytical devices. The conduits may transmit material into digesters in appropriate amounts including controlling the amount of liquid added to solid material. Collected urine may be stored for water reclamation. Sensors may confirm the absence of fecal matter in collected urine or detect contamination. After separate analysis, feces and urine may be combined through connecting conduits then disposed of in the sewer system or sent to a composting device or waste digester.

摘要： The tandem differential mobility spectrometer (DMS)-ion modulator instrument provides improved resolution relative to traditional DMS for molecules with larger masses. The instrument includes multiple ion-bunching electrodes, each with an AC field synchronized to the transit time of the ion flow which is positioned downstream of a DMS. The ion bunching electrodes produce each a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.

摘要： Disclosed herein are wireless devices operable at intermediate wireless at ranges of thousands of meters, utilizing packets that include a preamble and a data payload. Devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and other devices needing a communications link. A digital spread-spectrum frequency hopping rotation is used, wherein packet transmissions rotate through frequency sequences. A spectrum-impact-smoothed channel set is fashioned using sequences that each specify a unique preamble frequency relative to the other sequences and channels. The set is traversed as packets are transmitted, thereby distributing the focused radio-frequency emission impact of packets having long preambles over time. Packet acknowledgments are deferred until a group of packets in a stream has been exchanged. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
