Abstract: Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include contact elements. At least some of the contact elements may be configured to remain in contact with each other when a force is applied between the assemblies.

Abstract: Bearing assemblies, apparatuses, systems, and methods include bearing assemblies with bearing elements configured to accommodate axial movement.

Abstract: Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a force is applied between the assemblies.

Abstract: Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include bearing surfaces defining an at least partially conical surface.

Abstract: Bearing assemblies, apparatuses, systems, and methods include bearing assemblies where one of the bearing assemblies may include angled bearing surfaces having a planar shape.

Abstract: Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a rotational force and/or a thrust force is applied between the assemblies.

Abstract: The toilet bowl separately collects urine and feces for analysis or other uses. The toilet bowl includes a toilet bowl wall with at least two holes in it. The first hole is a fecal collection aperture positioned below a user where a user may defecate into it. The second hole is a urine collection orifice through which a user's urine may flow. The two holes may be separated by a ridge which may act like a dam to inhibit cross-contamination of collected feces and urine. Conduits may connect to the two holes to direct the waste into analytical devices or containers for additional uses including composters and digesters which produce clean energy.

Abstract: 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.
