Abstract: An optical system for use in an Earth-orbiting satellite includes a plurality of image sensors disposed on a focal plane having a reference axis orthogonal thereto, optics configured to focus incident light onto the image sensors, a piezoelectric actuator coupled to the image sensors and configured to translate the image sensors in at least two axes each orthogonal to the reference axis, and at least one controller operably coupled to the plurality of image sensors and the piezoelectric actuator. The image sensors are configured to generate at least one image frame from light detected by the plurality of image sensors, the image frame including a target star and at least one guide star.

Abstract: A general method of cooling and maintaining the uniform temperature of an extended structure is provided with specific application discussed of keeping a superconducting coil at cryogenic temperatures in the presence of external heat loads that may be variable in space and time. The approach embeds the structure to be cooled (208) into the vapor space (108) of a heat pipe assembly (202), which consists of an outer wall (116), a fluid wicking mechanism (110, 114), thermal insulation (118) and a mechanism for heat extraction, such as the cold tip (206) of a cryocooler (204).

Abstract: A sprinkler apparatus comprises a water wheel that is configured to be alternatively driven in a first wheel direction by a first fluid flow and a second wheel direction by a second fluid flow. The water wheel drives a water tube having at least one fluid outlet. The water tube is moveable in a first tube direction in response to the water wheel being driven in the first wheel direction, and is further moveable in a second tube direction in response to the water wheel being driven in the second wheel direction. The sprinkler apparatus further comprises a switch wheel positioned to receive an initial fluid flow and generate the first and second fluid flows therefrom. In particular, when the switch wheel is in a first position, the first fluid flow is generated. When the switch wheel is in a second position, the second fluid flow is generated.

Abstract: A sprinkler apparatus comprises a spray tube configured to move between a first side position and a second side position. The sprinkler apparatus also comprises a first side adjustment mechanism and a second side adjustment mechanism. Each adjustment mechanism comprises markings indicating lesser to greater degrees of sprinkling coverage area. The sprinkler apparatus further comprises a coverage indicator component attached to the spray tube. The coverage indicator component includes at least one window defined therein. The first side adjustment mechanism and the second side adjustment mechanism are independently moveable in relation to the coverage indicator such that the markings on the first side adjustment mechanism and the second side adjustment mechanism are selectively viewable to the user through the window. The positioning of one of the markings within the window results in a related degree of sprinkling coverage area by the sprinkler apparatus.

Abstract: A ground handling system for an airship which comprises a first track system to allow a plurality of docking carts to move from a hangar to a weathervane/launching/landing ring R. The docking carts are configured to complete a second track system. Carried by each of the docking carts is a mooring cart that carries a mooring structure. Upon the completion of the second track system by each of the docking carts, the mooring carts are able to move about the second track system. Thereby allowing the airship to be oriented in a desired manner to facilitate its launch or landing.

Abstract: A method for providing a mobile emissions reduction credit or other tradable commodity (15) comprising the steps of identifying an emissions reduction technology for a pollutant (20), providing a portable emissions measurement system (PEMS) adapted to measure emissions of the pollutant (21), providing a mobile source (16), applying the emissions reduction technology to the mobile source to provide a modified mobile source (25), connecting the PEMS to the modified mobile source (26), taking measurements of the modified mobile source (28), analyzing the measurements to develop a modified emissions amount (29), determining a target emissions amount (19), determining the difference between the target emissions amount and the modified emissions amount (30), and converting the difference between the target emissions amount and the modified emissions amount into a tradable commodity (31).

Abstract: An optical flow is disclosed having a shell with a first portion and a second portion. The first portion provides a light entry aperture, and the second portion provides an imaging aperture. An inlet tube and an outlet tube are retained between the first portion and the second portion. A viewing assembly is retained between the first portion and the second portion. The viewing assembly includes a reference plate and a flow channel. The flow channel fluidly communicates with the inlet tube and the outlet tube. The reference plate extends from the shell to serve as a repeatable reference point for properly positioning the optical flow cell.

Abstract: An automated library system having multiple storage cells for storing multiple data cartridges. Rails are provided adjacent to the storage cells to guide one or more robots among the storage cells. Primary coils are disposed proximate the rails. A power supply produces an alternating current in the primary coils. One or more magnetic cores are mounted on each robot. Each magnetic core is adjustable to form a normally gap-less closed magnetic path, and a gapped magnetic path when transitioning between primary coils. Alternating currents in the primary coils induce secondary alternating currents in secondary coils wound around the magnetic cores. The secondary alternating currents are controlled and converted into mechanical movement that include loading and unloading the data cartridges to and from the robots, and moving the data cartridges along the rails.

Abstract: Methods for packaging Metarhizium fungal cultures or conidia are described. In one embodiment, the fungal culture is provided within an insect infection chamber that attracts insects, then infects them with a lethal dosage of fungus, where the packaging maintains high humidity within the chamber, allows free exchange of gases, and is impermeable to microbes, including fungal spores, viruses, and bacteria. In a second embodiment, the fungal conidia are packaged under conditions which maintain high viability even after long-term storage at both 25.degree. C. and 37.degree. C., i.e., low relative humidity and oxygen. The conidia can then be reactivated for the use in the control of insects such as cockroaches, flies, ants, soft-bodied insects, turf pests, and caterpillars.
