Abstract: A method of operating a gas turbine engine including an engine core including a turbine, compressor, combustor to combust a fuel, and core shaft connecting the turbine and compressor; a fan upstream of the engine core; a fan shaft; a gearbox that receives an input from the core shaft and outputs drive to the fan via the fan shaft; a primary oil loop system to supply oil to the gearbox; and a heat exchange system. The method includes controlling the heat exchange system to adjust fuel viscosity to be lower than or equal to 0.58 mm2/s on entry to the combustor at cruise conditions.

Abstract: A medical waste fluid collection cart may include a container assembly and a suction tube having a lumen extending through the suction tube. The suction tube may communicate with the container to deposit waste fluid from a surgical site in the container. The container assembly may include a container, a base forming a bottom of the container, and a lid assembly. The base may include an interior surface defining a draining opening. The interior surface may extend along a ramped path toward the drain opening. The lid assembly may include a lid ring and a lid capable of engaging each other with a twist lock mechanism. The lid ring may engage the container and the lid may cover at least part of a central opening to the container. The container may have a window and a tinting assembly. The container assembly may have a vacuum level detection system.

Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: A power tool is provided including a tool housing including a motor housing and a handle portion extending longitudinally from the motor housing; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack; and a brushless DC (BLDC) motor including an electronically-commutated stator assembly and a rotor assembly configured to rotate with respect to the stator assembly, the stator assembly comprising a stator lamination stack sized to be received within the motor housing having a circumference of approximately 140 to approximately 190 mm. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.

Abstract: A method and apparatus for simulating a hand grenade in a training environment. The hand grenade includes dead reckoning to determine location after leaving a thrower. By knowing a location of the thrower and subsequent path after leaving the thrower, the explosion location and simulated damage to targets can be determined. The simulation can determine the effect of obstructions between the explosion location and nearby targets.

Abstract: An actuating device has a cartridge within a fixed casing. A card-like key has a key formation which, during insertion of the key into the cartridge, displaces a finger formation connected to an interference formation, which is then aligned with a gate of a gate member fixed to the casing. The gate allows passage to the interference formation allowing the cartridge to be displaced in unison with the key. An actuating formation on the cartridge is provided to actuate a lock or similar device.
