Abstract: Systems and methods used to perform touchless 3D scanning of a patient’s face in the prone position are disclosed. In some embodiments, the systems include a rotatable 3D scanning device to capture 3D spatial data points of the patient’s face and a reference frame. 3D digital mesh models are generated from the 3D spatial data points. A patient 3D digital mesh model is registered with a patient 3D model and a reference frame digital mesh model is registered with a reference frame 3D model. The 3D scanning device can include a handheld rotatable 3D scanner member or a mechanically rotatable 3D scanner member.

Abstract: Systems and methods for monitoring, calculating, and/or optimizing engine emissions produced in operating motorized equipment in well site operations or other jobs are provided. In one embodiment, the methods comprise: providing a set of exhaust emissions rates for one or more engines at a job site as a function of a speed of each engine and total brake horsepower to be provided by each engine; identifying one or more operating speeds or transmission gears for the one or more engines during an operation at the job site based at least in part on the set of exhaust emissions rates for the one or more engines; and operating the one or more engines at the one or more operating speeds or transmission gears during an operation at the job site.

Abstract: Systems and methods may be configured to monitor, calculate, and optimize diesel fuel consumption for dual-fuel engines. For example, a method may include performing a well site operation at first operating parameters with a dual-fuel engine configuration operating at first engine parameters, wherein the dual-fuel engine configuration comprises one or more dual-fuel engines; changing the first operating parameters to second operating parameters and the first engine parameters to second engine parameters; determining a maximum natural gas substitution percentage in a fuel comprising a natural gas/diesel mixture for at least one of the dual-fuel engines at the second operating parameters and the second engine parameters; and changing a fuel composition supplied to the at least one of the dual-fuel engines based on the maximum natural gas substitution percentage.
