Abstract: A machine for dispensing an individual portion of a frozen dessert may include a cartridge cart having walls forming a cavity having a longitudinal central axis and configured to accommodate a cartridge. The cartridge may include a tube having first and second ends, a nozzle disposed at the first end, and a piston disposed between the nozzle and the second end and configured to slidably move along the tube. The individual portion of the frozen dessert may be contained within the tube between the nozzle and the piston. The machine may also include a plunger, a drive source operably coupled to the plunger and configured to drive the plunger along the central axis, and a support configured to support the first end of the cartridge such that actuating the drive source causes the individual portion of frozen dessert to dispense through the nozzle.

Abstract: In connection with a data distribution architecture, client-side “deduplication” techniques may be utilized for data transfers occurring among various file system nodes. In some examples, these deduplication techniques involve fingerprinting file system elements that are being shared and transferred, and dividing each file into separate units referred to as “blocks” or “chunks.” These separate units may be used for independently rebuilding a file from local and remote collections, storage locations, or sources. The deduplication techniques may be applied to data transfers to prevent unnecessary data transfers, and to reduce the amount of bandwidth, processing power, and memory used to synchronize and transfer data among the file system nodes. The described deduplication concepts may also be applied for purposes of efficient file replication, data transfers, and file system events occurring within and among networks and file system nodes.

Abstract: A trial humeral prosthesis may include a trial stem for implantation into a humerus, and a trial proximal body configured to couple to a trial articulating component. A plurality of trial spacers may be configured to couple the trial stem to the trial proximal body, the plurality of trial spacers including a first trial spacer and a second trial spacer. The first and second trial spacers may each include a proximal post and a tab extending radially outward from the proximal post, and a distal body having a larger outer diameter than an outer diameter of the proximal post, a slot being formed in the distal body. The slot of the distal body of the first trial spacer may be configured to receive the tab of the second trial spacer when the proximal post of the second trial spacer is received within the distal body of the first trial spacer.

Abstract: A universal targeting apparatus includes a generally U-shaped body having one end configured to be coupled to the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body. An arm is rotatably mounted to the mounting portion of the U-shaped body and includes bores defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle of a transverse aperture in the intramedullary implant. The arm can be rotated so an appropriate one of the angled bores is aligned with the transverse aperture to serve as a guide for creating targeting holes in the bone.
