摘要： Pointers are added to a 3D volumetric dataset to help the user visualize the direction of blood flow. A 3D volume containing at least one blood vessel is created. Next, the direction of the blood flow is determined. Next, at least pointer is placed into the 3D volume in an aligned fashion with the direction of blood flow such that the 3D volume is modified. Next, the modified 3D volume is displayed on a head display unit, such as an augmented reality or virtual reality display. Next, at least one pointer is advanced to a new position for additional modification of the 3D imaging volume.

摘要： A method of de-watering during intermittent dry running periods with a self-priming centrifugal pump is presented. Centrifugal pumps, as opposed to diaphragm pumps, are advantageous because they are less expensive and can provide greater capacity. The shaft seals are sensitive, however, to frictional heating when water flow is interrupted. In some situations, this fractional heating may desiccate self-priming. The inventive concept provides a continuous stream of pressurized water moving through the pump to cool the seal and sustain priming capability without substantially impairing the ability of the pump to resume wet operation.

摘要： A computer-implemented method and solar focusing apparatus is presented. A spacecraft system is placed in orbit around a sun, the spacecraft system including a lens element focusing divergent energy received from said sun into generally parallel energy. A ground receive element on earth receives the generally parallel energy from the spacecraft system. A control element is provided and is in communication with the spacecraft system and the ground receive element.

摘要： A display case having end jamb lighting module and a center mullion lighting module is disclosed. The lighting modules include a shell and at least one substrate whereon lighting elements are mounted. The shell defines engagement slots used to affix the substrate to the shell. The shell defines an aperture allowing light from the lighting elements to be projected out. The lighting module may include a second substrate upon which electrical components are mounted, the electrical components for conditioning input power for the lighting elements. A reflective portion of the shell or a separate reflector mounted on the shell operates on the light to form a desired spatial distribution of light. An optical cover covers the aperture. The center mullion lighting module can include a third substrate for mounting of lighting elements. Alternatively, the center mullion lighting module can be formed by combining two end jamb lighting modules.
