SPRING BARREL MODULE

The invention concerns a spring barrel module having two chambers. A spring is located in the first chamber and a damper in the second chamber. The unidirectional damper is implemented by a clutch means that connects the damper plate to the spring shaft when the tightened spring is released, whereby the rotation of the damper slows down. Correspondingly, the clutch loosens the connection between the damper plate and the spring shaft when the spring is tightened. In low temperatures (e.g. below 0 ~C degrees) the damper fails to dampen the rotation. The unidirectional feature of the damper improves both usability and durability. Breakage of the mechanical components of the spring barrel is prevented by an overload clutch, which means that the spring barrel module will tolerate even relatively rough handling of the equipment.

THERMAL ENERGY CONVERSION SYSTEM

A power generation system includes a first vessel having a generally constant volume and a second vessel having a variable volume. Thermal energy is supplied to an ideal gas within the first vessel in order to raise its temperature and pressure. The thermally compressed gas is then released into, and expands the volume of, the second vessel. The expanding volume of the second vessel expands raises a mass and/or strains an elastic member, thus storing gravitational and/or elastic potential energy. This stored potential energy can be released on demand by evacuating the second vessel, typically into a third vessel, and used to power a generator. Preferably, the potential energy is used to coupled to the generator using a planetary gear drive, such that a relatively small number of input rotations yields a relatively large number of output rotations.

REVERSIBLE PULL CORD MECHANISM AND SYSTEM

A reversible pull cord mechanism adapted for rotating a shaft in one direction when the pull cord is pulled in a first direction and rotating the shaft in the opposite direction when the pull cord is pulled in a second direction.

SPRING BARREL MODULE

The invention concerns a spring barrel module having two chambers. A spring is located in the first chamber and a damper in the second chamber. The unidirectional damper is implemented by a clutch means that connects the damper plate to the spring shaft when the tightened spring is released, whereby the rotation of the damper slows down. Correspondingly, the clutch loosens the connection between the damper plate and the spring shaft when the spring is tightened. In low temperatures (e.g. below 0 ~C degrees) the damper fails to dampen the rotation. The unidirectional feature of the damper improves both usability and durability. Breakage of the mechanical components of the spring barrel is prevented by an overload clutch, which means that the spring barrel module will tolerate even relatively rough handling of the equipment.

Portable power supply

A portable power supply which uses manual energy to be converted into electrical energy. Manual energy can be supplied in large quantities over a short period of time, whereas modern electronic equipment requires a small quantity to be available over a long period of time. In order to accomplish this the manual energy is stored in a medium such as a spring or an inertia wheel, which is then allowed to release the energy slowly into a generator to provide electricity.

COILED AND TWISTED NANOFIBER YARNS FOR ELECTROCHEMICALLY HARVESTING ELECTRICAL ENERGY FROM MECHANICAL DEFORMATION

Yarn energy harvesters containing conducing nanomaterials (such as carbon nanotube (CNT) yarn harvesters) that electrochemically convert tensile or torsional mechanical energy into electrical energy. Stretched coiled yarns can generate 250 W/kg of peak electrical power when cycled up to 24 Hz, and can generate up to 41.2 J/kg of electrical energy per mechanical cycle. Unlike for other harvesters, torsional rotation produces both tensile and torsional energy harvesting and no bias voltage is required, even when electrochemically operating in salt water. Since homochiral and heterochiral coiled harvester yarns provide oppositely directed potential changes when stretched, both contribute to output power in a dual-electrode yarn. These energy harvesters were used in the ocean to harvest wave energy, combined with thermally-driven artificial muscles to convert temperature fluctuations to electrical energy, sewn into textiles for use as self-powered respiration sensors, and used to power a light emitting diode and to charge a storage capacitor. 1.
