Abstract: Method and apparatus for assessing health of fracturing fluid pump assemblies and other wellsite equipment. For example, predicted data indicative of a first operational parameter of a pump assembly is generated utilizing: a model relating the first operational parameter to each of a plurality of second operational parameters of the pump assembly; and real-time data indicative of each of the second operational parameters. Health of the pump assembly is then assessed based on: the predicted data indicative of the first operational parameter; and real-time data indicative of the first operational parameter.

Abstract: A vehicle cabin arrangement for a vehicle body and a method for lighting a vehicle cabin and for displaying information using such a vehicle cabin arrangement are disclosed. A lighting device with a light-emitting surface directed towards the cabin interior space is provided on a ceiling section. The lighting device has separate lighting elements each having a dedicated light-emitting element surface, which lighting elements can assume different switch-on states and/or light emission states which differ in at least one property of the emitted light. A control device for controlling the lighting device is provided. The lighting elements are arranged so that, both in the direction parallel to the cabin longitudinal axis and in the direction perpendicular to the cabin longitudinal axis, element surfaces are arranged next to one another. The control device can control each lighting element individually with respect to its switch-on state and/or its light emission state.

Abstract: The invention is directed to a target device for proximal and distal locking of medullary nails without X rays. The proximal and the distal target devices each have a U-shaped part, wherein guide bores are disposed in the widened end areas of the legs of the U-shaped parts. The medullary nail is fixedly connected with the proximal target device via a crosspiece and the proximal target device is connected with the distal target device by a pivotable and adjustable spacer. The distance of the end of the medullary nail from the distal target device is adjusted by a spacer element such that the center axes of the guide bores in the target devices are aligned with the center axes of channels or bores in the medullary nail, which channels communicate with the guide bores.
