Abstract: A method is provided for acoustically ejecting from a channel or other container a plurality of fluid droplets, each of which contains one or more particles or other localized volumes. The localized volumes, which can be living cells, are ejected towards sites on a substrate surface, a container, or a channel. An integrated cell sorting and arraying system is also provided that is capable of sorting based upon cellular properties by the selective ejection of cells from a carrier fluid. The cells can be ejected with adjustable velocity and trajectory. The ejected cells can be directed to form an array, wherein each site of the array can contain a single cell. Additionally provided is a method of forming arrays of single live cells more efficiently, rapidly, flexibly, and economically than by other cell array approaches.

Abstract: Golf club heads include: (a) a body member constructed, at least in part, from cellular structure material; (b) a ball striking face engaged or integrally formed with the body member; and/or (c) a shaft member engaged with the body member. Weight savings realized through the use of lightweight cellular structure materials allows additional weight to be placed at other desired locations in the club head structure. By adjusting and selectively placing weight in the club head structure, the club head's moment of inertia, center of gravity, and/or stability characteristics may be favorably affected and/or the resulting ball flight may be influenced and/or customized to a specific individual golfer, to provide a more controlled, consistent, and/or straight ball flight.

Abstract: Devices and methods are provided for reducing the uncontrolled electrostatic charges that can alter the volume and/or trajectory of a droplet, which is typically ejected through the application of focused acoustic radiation. Also provided are reservoirs and substrates, e.g., well plates formed from a material that is at least partially nonmetallic or polymeric and either has an electrical resistivity of no more than about 1011 ohm-cm, has a surface electrical resistivity of no more than about 1012 ohm/sq, or both.

Abstract: Methods and devices are disclosed that use focused acoustic energy to generate solid particles containing at least one compound of interest. Focused acoustic radiation serves to eject droplets containing a compound of interest dissolved in a solvent. The droplets are subjected to a condition that allows for the compound of interest to precipitate out of solution, thereby generating solid particles. The particles are typically of controlled size, composition, and/or structure. Often, particles of substantially identical size are generated.

Abstract: A method and device for generating solid particles using focused acoustic energy are provided. A solution of a compound of interest is provided in a solvent, which may be an aqueous fluid, a nonaqueous fluid, or a supercritical fluid. Focused acoustic energy is used to eject a droplet of the solution, which is then directed into or through an antisolvent that upon admixture with the solution droplet causes the compound in the droplet to precipitate. In a preferred embodiment, the solvent is an aqueous or organic liquid, and the antisolvent is a supercritical fluid.

Abstract: A method is provided for acoustically ejecting from a container that is preferably a channel, a plurality of particles or localized volumes that can be single living cells contained in fluid droplets toward sites on a substrate surface or alternatively or in addition thereto into containers or channels for deposition at a target array site or a container or channel by acoustic ejection. An integrated cell sorting and arraying system also is provided that is capable of selective sorting, into channels or other containers substantially transected by a common plane, parallel to a surface of the fluid, transecting the container from which cells are ejected by selective ejection of cells with adjustable velocity parallel to the fluid surface, and simultaneously selectively forming an array of cells on a substrate surface comprising an array of substantially planar sites is provided, wherein each site contains a single cell.

Abstract: A desktop organizer, particularly for CD's and computer discs, comprises an elongated base having a track with a slot extending axially therealong, end walls supporting the base and a rear wall extending perpendicularly between the end walls and parallel to the base. A support member includes a coiled spring mounted within an upper recess and affixed at its lower end within the base slot for spring urged movement of the support member to and fro along the base. The coiled spring provides a resilient force to the upwardly extending support member to maintain objects on the base between the support member and one of the end walls. The support member and associated track are detachable and may be reassembled along the rear wall or in the opposite direction along the base. The organizer may be mounted on a turntable and includes a plurality of legs mounted to the end members which permit stacking of several organizers or positioning of the organizer at a particular height.
