Abstract: A method for harvesting heavy mineral from a regolith may comprise: flowing a layer of particulate feedstock over a distribution chute having an uneven surface texture, the particulate feedstock comprising first particulates and second particulates that differ by at least one property; changing a momentum of individual particulates in the particulate feedstock while flowing over the distribution chute and/or after leaving the distribution chute such that the first particulates and the second particulates, on average, travel different lateral distances from the distribution chute; and collecting the particulate feedstock in a plurality of bins, wherein at least two of the bins are laterally spaced differently from the distribution chute.

Abstract: An infant bather includes a base and a cradle. The cradle is mounted with the base. The base includes a first surface and a second surface, wherein the first surface of the base is connected to at least one engagement member that is adapted to engage a support surface, such as an edge or bottom of a sink or the edge or bottom of a bath tub. The second surface of the base further defines a cradle interface, which defines a vertical axis that may extend substantially perpendicular to the base second surface. The cradle also defines a cradle first surface and a cradle second surface. The cradle second surface is configured to support an infant in a reclined position. The cradle first surface includes a base interface that is engageable with the cradle interface of the base.

Abstract: A combination drinking cup and snack container includes a first body having a first cavity sized to hold liquid, and a second body coupled to the first body, the second body having a second cavity sized to hold food items. The combination drinking cup and snack container also includes a lid coupled to the second body, the lid having at least one flexible member that inhibits food items from spilling out of the second body.

Abstract: A snack container for holding food items. The container includes a main body and a lid coupled to the main body. The lid includes a first section having an interior rim defining an opening. The lid further includes a second section coupled to both the main body and the first section. The second section is affixed to the main body along a first portion of the second section and not affixed to the main body along a second portion of the second section.

Abstract: A method and apparatus for controlling the motion of a cable-driven autonomous moored profiler. The profiler includes one or more buoyant members for buoying the profiler in the fluid, a winch, and a feedback controller for controlling the winch. The winch includes a spool, a device providing for varying rates of turning of the spool, and a flexible cable for winding onto and unwinding from the spool. A first end of the cable is carried by the profiler. The controller monitors an indication of the tension in the cable and controls the device in response thereto.

Abstract: An absorption meter determines concentration of chlorophyll a and pheophytin in liquids. Particularly, an immersible absorption meter has a light source, a reflective flow tube, a signal detector, and means for determining the difference between the absorption coefficients at a first wavelength and a second wavelength. The light source may further include a plurality of filters and a selector that selects the filters. The concentration of substances in liquids is determined by measuring the absorption of light at a first wavelength and at a second wavelength, determining the difference between the absorption coefficients for the first and second wavelengths, and converting this data into concentrations.
