Abstract: A surgery visualization system is described herein. The surgery visualization system includes a display monitor positioned in view of a surgeon and a support arm system including a first support arm and a second support arm. The first and second support arms are orientated such that the display monitor is visible to the surgeon between the first and second support arms. A 3D digital viewport coupled to the first support arm. A 3D digital microscope coupled to the second support arm. A computer system including a processor programmed to receive and process images from the 3D digital microscope and display the processed images on the 3D digital viewport and the display monitor.

Abstract: A gas compressor comprising a drum affixed to a rotating shaft, the drum including a plurality of compression channels between a common pressure zone and an interior surface of the drum distal to an axis of rotation. A static vane return assembly adjacent the compression channels includes vanes extending from an inlet at an outer circumference to the common pressure zone and directing gas into the common pressure zone, either through the vanes or via separate channels or ducts. Fluid inside the rotating drum forms an annular lake that is drawn through the vanes and into the common pressure zone. Fluid is then forced into the compression channels where gas in the fluid is compressed as it travels from the common pressure zone toward the interior surface. The pressurized gas is separated from the liquid prior to leaving the compression channel assembly while the liquid is returned to the lake.

Abstract: A seed sampling system is provided comprising an automated seed loading assembly operable to singulate seeds from a plurality of seeds or enable loading of individually stored seeds and an automated seed sampling assembly comprising at least one sampling module operable to remove tissue samples from one of the singulated seeds. The system also includes an automated seed transport assembly comprising at least one retention member operable to transfer the singulated seeds from at least one elevator unit of the seed loading assembly to the at least one sampling module of the seed sampling assembly. In connection therewith, the at least one sampling module includes multiple sampling locations, each associated with a sampler, where the at least one sampling module is operable to remove tissue samples from seeds at one of sampling locations while another one of the sampling locations is cleaned to remove residual seed tissue therefrom.

Abstract: A gas compressor comprising a rotating drum and a return assembly. The drum includes a compression channel assembly with compression channels between a common zone and a distal area. The compression channels may be formed by a plurality of V-shaped blocks. The return assembly draws liquid from an annular lake formed in the drum to a fluid outlet. A gas inlet in the return assembly mixes incoming gas with the liquid. An optional eductor connected to the gas inlet draws gas into the gas inlet. Fluid entering the common pressure zone is forced into the compression channels that compress the gas. Pressurized gas is separated from liquid in the fluid prior to leaving the compression channel. An inducer may be positioned between the fluid outlet of the return assembly and the opening of the centralized common pressure zone.

Abstract: A gas compressor comprising a substantially hollow cylindrical drum secured to a fixed shaft and configured to rotate a volume of fluid about a central axis. A plurality of eductors may be affixed to the shaft through support rods and positioned within an interior of the drum to receive a flow of fluid during rotation of the drum. A gas inlet along the fixed shaft comprises a channel through which gas external to the drum may be drawn into the eductors and compressed. Compressed gas accumulates within a central area of the drum and may be harvested through a gas outlet along the fixed shaft. Additional embodiments may comprise pitot tubes to manage a fluid level within the drum, and a cooling system to manage fluid temperature.
