The converter can be used, for example, to power logic devices in portable battery operated devices.

The invention combines the features of a supercharger, a turbocharger and turbo-compounding into one system, utilizing a hydraulic or mechanical continuously variable transmission to drive the turbocharger up to a specific speed or intake manifold pressure and then holding the ideal speed to keep it at the right boost pressure for the engine condition. The benefits of a supercharger, which is primarily good for high torque at low speed, and a turbocharger, which is usually only good for high horsepower at high speeds are merged. Once the exhaust energy begins to provide more work than it takes to drive the intake compressor, the invention recovers that excess energy and uses it to add torque to the crankshaft. As a result, the invention provides the benefits of low speed with high torque and the added value of high speed with higher horsepower or better fuel economy all from one system.

This invention provides a small, high efficiency, oil-free turbine-driven alternator (i.e. turboalternator) suitable for conversion of stored energy in a process gas to electrical power, facilitating recapture of energy during operation that would otherwise be wasted. The turboalternator includes a turbine and a generating device operatively connected together by a rotating shaft capable of rotating at high speeds. The rotating shaft is supported by foil gas bearings.

An exemplary power inverter comprises a push-pull inverter circuit that includes a transformer having a primary winding coupled to a DC bus and a secondary winding coupled to an AC bus, main power switches coupling each end of the primary winding to a DC return, and one or more supplemental power switches coupling at least one end of the primary winding to a snubber bus. The supplemental switch at a given end of the primary winding forms a buck-mode converter in combination with the primary winding and the associated free-wheeling diode at that end of the primary winding, and can be controlled by a switching controller to effect energy transfer between the snubber bus and DC bus. The switching controller can be configured to control power flow between the DC, AC, and snubber buses by controlling the common-mode and differential-mode voltages of the primary winding via main/supplemental power switch control.

An energy recovery system includes a fan and a wind turbine adapted to mount adjacent the fan to recover energy from the air flow generated by the fan.

An internal combustion rotary engine, self cooled, totally concentric and symmetric, dynamically variable compression ratio, capable of developing multiple Otto cycles in each rotation, by means using modules, composed mainly by a solenoid gate valve and three chambers operating at the rotor periphery, producing at low RPM, torsion of value near close at theoretical limit. High power/weight ratio, which increases substantially when number of modules increase, without drive shaft length increase; plus reduced internal friction, is a truly saver fuel machine; with volumetric asymmetry ratio between expansion and compression chambers, and that compression chambers working at beginning of the cycle at normal atmospheric pressure, it gives a fast rise pressure peak, because of the almost wedged form of that chambers. Proper for many types of combustion and class of fuels, including hydrogen, liquefied propane gas and efficient use of air compressed as external energy supply. Excels in aircraft use.

The intelligent glasses application system can be used for monitoring the real-time condition of the user, such as the emotional state, the motion state and the sitting posture of the user, and can send prompt to the user when the user real-time condition reaches an interference condition.

The invention describes a method for controlling a sensorless, brushless DC motor that is controlled via a bridge circuit preferably using pulse width modulation (PWM) having precommutation. According to the invention, in the braking operation each commutation interval is divided into two phases. A drive phase, lasting from the start of the commutation interval up to zero crossing in which the motor is controlled with the normal PWM, and a braking phase, lasting from zero crossing up to the next commutation time in which at least two motor phases are short-circuited and/or in which the PWM is operated with recovered energy. The efficiency of the control circuit is as low as possible so as to ensure that the braking energy is consumed in the control circuit.
