Abstract: An overhead fixture supports a plurality of cameras used to acquire images associated with a scene during operation of a facility. In one implementation, a first camera is mounted to the overhead fixture to acquire one or more images of a user, while a second camera is mounted to the overhead fixture to acquire one or more images of an inventory location or items at the inventory location. One or more light sources may be mounted on the overhead fixture and activated to produce light. The light may illuminate one or more of the user, the items at the inventory location, or other portions of the scene. Brilliance of the light sources may also obscure the cameras from observation by the user.

Abstract: An overhead fixture supports a plurality of cameras used to acquire images associated with a scene during operation of a facility. In one implementation, a first set of cameras are mounted to acquire images of faces of users, while a second set of cameras are mounted to acquire images of inventory locations. One or more light sources may be mounted on the overhead fixture and activated to produce light. The light may illuminate one or more of the users, the items, or other portions of the scene. Brilliance of the light sources may also obscure the plurality of cameras from observation by the users.

Abstract: Compositions containing phenolic antioxidant solutions are provided. The invention further provides methods of making and using such compositions as well as compositions that contain both biodiesel and at least one antioxidant concentrate solutions and blended fuel compositions containing biodiesel blended with other fuels.

Abstract: Methods and systems for upgrading hydrocarbon are described. The system can include a combustor and a nozzle reactor. The combustor can be used to produce a motive fluid suitable for use in the nozzle reactor. The motive fluid produced by the combustor and a hydrocarbon stream can be injected into the nozzle reactor to upgrade the hydrocarbon material. The systems and methods can also be integrated with a steam assisted gravity drainage system.

Abstract: Methods and systems for upgrading hydrocarbon on offshore platforms are described. Hydrocarbon material can be extracted from deposits under bodies of water and upgraded on offshore platforms, such as through the use of one or more nozzle reactors. The upgraded hydrocarbon material produced by the nozzle reactor, can than be transported back to shore through pipelines, in part due to the improved viscosity of the upgraded material.
