Abstract: A depth camera assembly (DCA) for depth sensing of a local area. The DCA includes a polarized light generator, an imaging device, and a controller. The polarized light generator modulates one or more optical beams emitted from an illumination source to generate modulated light, and projects the modulated light into the local area as polarized light having a first polarization. The imaging device receives light from the local area, the received light including ambient light and a portion of the polarized light reflected from the local area. The imaging device reduces an intensity of the received light having polarization different from a second polarization to generate filtered light substantially composed of light of the second polarization, and detects the portion of the polarized light having the second polarization using the filtered light. The controller determines depth information for the local area based on the detected portion of the polarized light.

The use of halo-illumination allows a user to see top, bottom, and both sides of the dog's mouth in a particular region, thus providing the user sufficient information as to whether they are effectively performing teeth cleaning of the dog.

Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to hydroprocess opportunity feedstocks (i.e., lower quality heavy oils or lower quality feedstock blends) while maintaining or increasing the rate of production of converted products. The dual catalyst system improves the ability of the upgraded ebullated bed hydroprocessing system to accommodate and withstand negative effects of periodic use of opportunity feedstocks (e.g., without significantly increasing equipment fouling and/or sediment production). In some cases, an upgraded ebullated bed reactor using the dual catalyst system can hydroprocess opportunity feedstocks while decreasing equipment fouling and/or sediment production.

Abstract: Method consists of placing a flexible container within a rigid frame and expanding the container by pneumatic or hydraulic pressure such that the walls of the container conform to the inside walls of the rigid frame thus forming a well-defined chamber. The system has the capability of reducing the volume of the chamber by adjusting the distance between the walls of the rigid container. The methods and systems so described are applicable to closed sterile systems that employ immunomagnetic isolation or purging of components from blood products. By providing a fixed volume and at least one surface upon which targeted entities can be magnetically deposited, target cells in the case of positive isolations can be magnetically held, flushed with wash buffers over them to remove entrapped cells and finally the recovery of product of very high purifies and at high yields.
