Abstract: A method includes: receiving a plurality of measurable engine parameters captured using aerial vehicle sensors; reading an estimated parameter value from each of a plurality of thermodynamic surface maps, wherein the plurality of thermodynamic surface maps have a first dimension comprising a first thermodynamic engine parameter, a second dimension comprising a second thermodynamic engine parameter, and a third dimension comprising a third thermodynamic engine parameter whose value is related to the first thermodynamic engine parameter and the second thermodynamic engine parameter, wherein the estimated parameter values are read from the third thermodynamic engine parameter from each of a plurality of thermodynamic surface maps based on selected values for a first thermodynamic engine parameter and a second thermodynamic engine parameter; estimating an unmeasured temperature value based on the estimated parameter values read from the plurality of thermodynamic surface maps; and controlling the turbine engine b

Abstract: A laser level includes a housing, a pendulum pivotably mounted to the housing, and a laser diode assembly disposed on the pendulum. A gimbal assembly is employed for pivotably mounting the pendulum to the housing. The gimbal assembly includes a frame connected to the housing, a first pair of bearings disposed on the frame, an axle extending through the first pair of bearings, a body disposed on the axle and pivotably supporting the pendulum, and a second pair of bearings disposed between the body and the pendulum. The first pair of bearings is disposed on one side of the second pair of bearings.
