Abstract: Provided herein are implants and methods for producing implants. In at least one embodiment, the implants include sheet-based, triply periodic, minimal surface (TPMS) portions. According to one embodiment, the TPMS portions include a gyroid architecture that provides for improved osseointegration and mechanical performance over previous implants due to novel ratios of porosity to compressive strength, among other features.

Abstract: A gas turbine engine and method of starting, the gas turbine engine having a rotor comprising at least a shaft mounted compressor and turbine, with a casing surrounding the rotor. The method comprises an acceleration phase, a bowed-rotor cooling phase, during the acceleration, and a combustion phase. The bowed-rotor cooling phase comprises a time where the rotational speed of the rotor is maintained below a bowed-rotor threshold speed until a non-bowed condition is satisfied, wherein the air forced through the gas turbine engine cools the rotor. The combustion phase occurs after the bowed-rotor cooling phase and upon reaching the combustion speed, wherein fuel is supplied to the gas turbine engine is turned on.

Abstract: A system for active co-boresight measurement includes a detector, first and second steering mirrors, and a controller. The detector detects a portion of a transmission beam emitted by a transmitter and a portion of a received beam received from a remote terminal. The controller instructs the first steering mirror to scan the detected portion of the received beam to determine an alignment position. The controller controls a position of the first steering mirror to align the portion of the received beam with the alignment position on the detector, and controls a position of the second steering mirror to align the detected portion of the transmission beam with a defined position on the detector. The detected portion of the received beam at the alignment position and the detected portion of the transmission beam at the defined position correspond to the received beam and the transmission beam being aligned.

The semiconductor chip enables manipulation of the vehicle based on communication of the cognitive state information to a component of the vehicle.

Abstract: A compact, energy efficient air cooling system for a rotating shaft bearing module includes a Coanda surface having a periphery that smoothly curves from a radial center to axial alignment with a side of the module. A fan blade mounted on the shaft directs an airflow radially parallel and adjacent to the Coanda surface, causing the airflow to be bent by the Coanda effect from radial to axial, and to be directed along the side of the housing. Embodiments that can be applied to existing housings include a Coanda panel adjacent to the housing end face. A double suction fan blade can draw both external air and air from between the panel and the housing. In other embodiments the housing end face itself is a Coanda surface. A fan cover can have an inwardly curved periphery that forms a reduced gap or nozzle with the Coanda surface.
