A human power conversion system incorporates two or more electric machines to aid in the powering of a vehicle through energy conversion. A first electric machine is coupled with the human powered input and acts as a generator when a human power input is not sufficient to produce electrical power that is provided to a second electric machine that propels the vehicle. The vehicle may be a bicycle and the first electric machine may be coupled to the crank. A bi-coupled electric machine including the first and second electric machines with a common rotor or stator may be employed and coupled to the crank and/or the driven wheel. Power produced by the first electric machine may be provided directly to the second machine or may be stored in a battery and used to propel the vehicle or power other electronic components.

A drive assembly having a motor accommodating bore for an electric motor, the bore being directed perpendicularly into an end face of a block-like accommodating body, and having a motor housing for accommodating a bearing provided for a motor shaft of the electric motor the bearing being fixed in an end-side motor housing section which extends into the motor accommodating bore. The invention provides for the electric motor to be frictionally fixed and centered in the motor accommodating bore by a motor holder that is fastened to the end-side motor housing section and projects into the motor accommodating bore.

An oil cooler is disclosed that comprises a base plate including a recessed portion defined by an interior wall and an exterior wall and including an inlet port and an outlet port. The base plate further includes a divider wall positioned in the recessed portion and extending between the exterior wall and the interior wall to separate the inlet port and the outlet port, a plurality of protrusions arranged in the recessed portion to provide a plurality of tortuous flow paths through which oil flows from the inlet port to the outlet port, and a first set of cooling fins formed on a surface of the base plate opposite the recessed portion. A cover plate is attached to the base plate so as to cover the recessed portion and thereby define a cavity to circulate the oil therethrough, the cover plate including a second set of cooling fins formed thereon.

A low frequency micro oscillator-driven oscillating system including at least one electric oscillation generator operative to produce oscillations at a first frequency, at least one oscillated article, at least one intermediate element, having at least one resonant frequency lower than the first frequency, the at least one intermediate element being oscillated by the at least one electric oscillation generator and being operative to cause the at least one oscillated article to oscillate and a power supply circuit, supplying electrical power intermittently in a periodic manner to the at least one electric oscillation generator, thereby causing the at least one oscillated article to oscillate at at least one second frequency, lower than the first frequency.

An electrical power generating apparatus for generating electrical power using a generator connected directly or indirectly to a flywheel is disclosed. The apparatus comprises platforms, protrusions, generators, flywheels and other components. The platforms are configured to be laid on a surface and easily allow an object, e.g., a vehicle to traverse over the platforms. Each protrusion is configured to move downward and upward through apertures located in a top portion of the platform. The protrusions interact with reset members. The protrusions move in a linear/angle downward/downward-upward motion when the object pushes/strikes/depresses the protrusions. Each protrusion is connected in an operative manner to a shaft via a gear, and/or to a lever which is connected in an operative manner to shaft, thereby rotating the shaft by converting linear motion to rotational motion. A generator, flywheel, and gearbox can be coupled to the shaft.

An integrated linear parallel hybrid engine is described. Embodiments of the integrated parallel hybrid engine can include, but are not limited to, a linear electric motor integrated into an internal combustion engine. The integrated linear parallel engine can include a plurality of pistons each having magnetic properties, a plurality of electromagnets, a power supply, and an internal combustion engine. The magnetic pistons can be implemented to act as normal pistons in the internal combustion engine and to act as rotors for the linear electric motor.
