Abstract: Methods and systems for cooling an electric motor are provided. An electric motor system, in one example, comprises a rotor with a plurality of axial air conduits, a first balancing plate positioned on a first axial side of the rotor, the first balancing plate comprising an inlet air duct and an outlet air duct, and a second balancing plate positioned on a second axial side of the rotor, the second balancing plate comprising an inlet air duct and an outlet air duct. In the electric motor system, the inlet air duct in the first balancing plate is radially offset from the inlet air duct in the second balancing plate.

Abstract: A patient support apparatus for supporting a patient in a prone position during a surgical procedure is provided, including an open patient support frame suspended above a floor and a base for supporting and suspending a the frame during a surgical procedure, the base including a pair of spaced vertically translatable subassemblies reversibly attachable to the frame by a pair of fail-safe rotatable connector attachment mechanisms to prevent inadvertent uncoupling of a first and second outer end of the frame from the base structure.

Abstract: Various methods and systems are provided for a system for cooling an electric motor that includes a rotor shaft rotatably mounted inside a motor housing, a lamination stack integrally connected to the rotor shaft, an encoder-end balance plate integrally connected to a first end of the lamination stack and a first end of the rotor shaft, an output-end balance plate integrally connected to a second end of the lamination stack and a second end of the rotor shaft, an oil supply coupled to the output-end balance plate and the rotor shaft. A closed-looped coolant pathway is formed between the transmission, the rotor shaft, the encoder-end balance plate, the lamination stack, and the output-end balance plate.

Abstract: A handheld mobile device may be configured for use within a cockpit or cabin of an aircraft. The handheld mobile device may include a display and memory that includes an application configured to utilize the display. The handheld mobile device may also include a processor coupled to the memory. The application, via the processor, may be configured to receive aircraft-specific configuration data. The application may also receive, from a tracker module, input data corresponding to blade height and position. The application may additionally receive airframe vibration data from an accelerometer module. The application may further calculate recommendations regarding track and balance. The application may also further output, via the display, the track and balance recommendations.
