A portable electric nailing gun operating from a power supply. The motor accelerates a flywheel, which at the appropriate energy state is coupled through a mechanism to an anvil acting directly on the nail. The actuation is governed by a control circuit and initiated from a trigger switch. The stored energy delivered from the motor is coupled to the output anvil drives the nail. At least one position of the output anvil is sensed and once the nail is driven, the power is disconnected from the motor. This method uses a direct acting clutch and a harmonic motion nailing mechanism to reduce wear and increase robustness of the nailer. Elastic elements are used to limit stresses during the impact periods. The electrical control circuit and sensors allow precise control and improve safety. The power supply is preferably a rechargeable low impedance battery pack.

A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.
