    Abstract: Aspects of the disclosure provide an electric actuator including a first driving source coupled to an output through a first pathway created by a transmission, a second driving source coupled to the output though a second pathway created by the transmission that, upon the electric actuator losses electrical power to the electric actuator, causes the output to be positioned at a fail-safe position, a differential coupled to the first driving source and the second driving source through a third pathway created by the transmission to store energy from the first driving source in the second driving source, and a switching controller that is configured to control switching the transmission between the first pathway, the second pathway, and the third pathway.

    Abstract: An electric phaser for dynamically adjusting a rotational relationship of a camshaft with respect to an engine crankshaft of an internal combustion engine includes an electric motor and a tapered roller drive. The tapered roller drive includes a sun, rollers, a carrier, at least one ring, and at least one load generator providing an axial load. The rollers are maintained in rolling engagement with the sun and the ring without the use of teeth. In some embodiments, the tapered roller drive is based on a fixed-sun design. In other embodiments, the tapered roller drive is based on a split ring design.

    Abstract: Infinitely variable motion control (IVMC) using Transgear gear assemblies provides rotary motion control without any requirement for connecting or disconnecting gear meshes or use of a clutch. A bevel, miter, ring or spur gear Transgear gear assembly may be defined as a gear assembly having three or four of variables, input, output and control, assigned in a manner so as to provide, for example, one of accumulation of inputs and direction control. A four variable Transgear gear assembly may be one of a spur gear Transgear gear assembly having an additional ring gear surrounding a set of planetary gears or a bevel gear Transgear gear assembly having a double bevel gear, an outer bevel gear and a bevel gear meshing to the outer bevel gear sleeve surrounding an inner beveled gear and comprising three orthogonal carrier shafts. Rather than two sets of three variable Transgear gear assemblies connected in series or in parallel, a four variable Transgear gear assembly may provide, for example, a direction control function with just one gear assembly with two of the four variables assignable as control variables.

    Abstract: A transmission for transferring torque from a prime mover includes a first input shaft adapted to be driven by the prime mover, a second input shaft, an output shaft and an epicyclic gearset. The gearset includes a ring gear being driven by the first input shaft, pinion gears being driven by the ring gear, a sun gear driven by the second input shaft and driving the pinion gears, and a carrier driving the output shaft. A reaction motor drives the second input shaft. A controller controls the reaction motor to vary the speed of the second input shaft and define a gear ratio between the first input shaft and the output shaft based on the second input shaft speed.
