A starter-generator includes redundant motor / generator sets disposed within a common housing. Each motor / generator set is electrically and mechanically independent of one another, with the exception of a common input / output gear. The starter-generator is configured such that if one of the motor / generator sets experiences a predetermined torsional load, it will decouple from the input / output gear, allowing the other motor / generator set to continue operation uninterrupted.

Three-, and four-dimensional ("3-D" and "4-D") volume radiation memories store multiple binary bits of information-typically about five to ten and more typically eight such bits-in the same physical volumes on several different photochromic chemicals co-located in the volume. Each of the multiple photochromic chemicals is individually selectively written with an individually associated pair of radiation beams of an appropriate combined frequency-i.e., a "color"-and energy by a process of two-photon ("2-P") absorption. All the multiple information bits that are stored within all the photochromic chemicals in each addressable domain are read in common, and induced to simultaneously fluoresce, again by process of 2-P absorption. The fluorescence of each of different photochromic chemical in each addressed domain-which fluorescence is selective in accordance with the written state of each such photochromic chemical-is separated from, and is separately detected from, the fluorescence of all other photochromic chemicals because it is of a unique color, and is spatially steered to an associated detector array, normally a Charge Coupled Device (CCD), by a monochromator, normally a prism. Exemplary fluorescent photochromic chemicals are spirobenzopyran, rhodamine, cumarin and anthracene. Suitable groups of photochromic chemicals are formed from individual photochromic chemicals exhibiting narrow, sharp, separate spectra of absorption and of emission suitably distinct from each other, and where no chemical's fluorescent emission energy overlaps the absorption energies of any other chemicals.

A system used for alignment of a vehicle suspension and axle includes a pear-shaped cam that is rotatable relative to one of two spaced plates of a hanger bracket. An aperture and nose in the cam plate is aligned with an elongated opening in the bracket plate. The cam further includes a pin that is configured for insertion and movement within an arcuate aperture in the bracket plate. A fastener extends through the aperture and the nose of the cam, through the elongated openings in the bracket plates, and through the suspension control arm. Rotation of the cam causes a corresponding movement of the pin along the arcuate-shaped aperture of the bracket and of the fastener along the elongated openings of the bracket.

A floor latch assembly includes a mounting bracket secured to the seat cushion of an automotive seat. A latch hook is pivotally connected to a side wall of the mounting bracket and engages a striker pin on the floor of a vehicle. A cam lock hook is pivotally connected to the mounting bracket and engages the latch hook to create a locking mechanism for securing the seat to the striker pin. An anti-separation member maintains alignment of the latch hook and the cam lock hook to enhance the locking mechanism.

A Sabatier process involving contacting carbon dioxide and hydrogen in a first reaction zone with a first catalyst bed at a temperature greater than a first designated temperature; feeding the effluent from the first reaction zone into a second reaction zone, and contacting the effluent with a second catalyst bed at a temperature equal to or less than a second designated temperature, so as to produce a product stream comprising water and methane. The first and second catalyst beds each individually comprise an ultra-short-channel-length metal substrate. An apparatus for controlling temperature in an exothermic reaction, such as the Sabatier reaction, is disclosed.
