  • Patent number: 10188039
    Abstract: Methods and systems are described for providing a local electrical power source at a header of a combine harvester. An alternator is mechanically coupled to a header backshaft. The header backshaft is mechanically coupled to a drive mechanism of the combine harvester to cause rotation of the header backshaft which, in turn, causes the alternator to generate electrical power. A power supply circuit transferred electrical power from the alternator to one or more electric devices mounted on the header. In some implementations, the header does not include any physical cables between the combine and the header.

  • Patent number: 9279427
    Abstract: A cooling system for a generator of a vehicle has an engine, a generator and a wind collection box. The generator has a rotor driven by the engine and a fan synchronously rotating with the rotor. The wind collection box is connected to the generator via a first guiding tube. The fan draws exterior air from the wind collection box and the first guiding tube to allow the exterior air to flow through the generator. Thus, heat in the generator that is mounted in an airtight engine compartment is dissipated.

  • Patent number: 8344693
    Abstract: A rotationally rechargeable electrical apparatus includes an electronic device with a back, a center of mass and a battery. An electrical generator at the back of the device has a rotor secured to the device and a stator having a flat contact surface extending parallel to the back of the device. The rotor and stator are rotatably connected together so that they can rotate relatively about an axis that extends perpendicular to the contact surface and passes through the center of mass. A voltage regulating circuit is connected electrically between the generator and the battery so that when the apparatus is placed on a support so that the contact surface frictionally engages the support and the device is spun about the axis, the generator produces an electrical output that is conditioned by the regulator circuit to charge the battery.

  • Patent number: 7514803
    Abstract: A working surface incorporates a means for transferring mechanical energy produced by a rotating member of the working surface so that the energy rotates a shaft attached to an alternator that charges a bank of 12 V batteries. The alternator is responsible for converting the mechanical energy being input by the rotating shaft to electrical energy that is fed to the batteries. The batteries transfer the energy into an inverter for use depending upon the required amount. Thereby, backup electrical power may be generated and stored, taking advantage of excess horsepower at cruise provided by a vehicle as well as better utilizing travel time. Additionally, the added cost of ownership and noise of a portable power generator is avoided.

The spring buffer is located between the first and second gears. The first and second gears are engaged with the rack and an axial gear of the electricity generator, respectively. An electricity output terminal of the electricity generator is connected to an electric device. As a result, the rack drives the first gear by means of gravity drop that forms during movement of the shock absorber to enable the electricity generator to produce electricity. Consequently, the shock-absorbable electricity-producing apparatus absorbs shocks and produces the electricity insensibly without causing burden and resistance.

An explosive projectile contains a fuze with a setback generator and associated fuze electronics. Upon initiation of projectile launch, the setback generator produces a voltage for use by the fuze electronics during flight.

When a projectile is fired, rapid acceleration thereof causes the fastener to break and the magnet to be displaced longitudinally within the surrounding coil, which decreases the magnetic field and induces a current in the surrounding coil. The induced current produces a voltage that is stored in a capacitor operably coupled to the setback generators which then is used to power the fuze electronics during flight.

The stator component (20) is secured to the housing (12), the rotor component (18) rotates relative to the stator component (20) and the crank assembly (14) is coupled to the rotor component (18). The crank assembly (14) is rotated by the user relative to the housing (12). As provided herein, rotation of the crank assembly (14) by the user results in rotation of the rotor component (18) relative to the stator component (20). In one embodiment, the control system (24) controls the amount of torque required to rotate the crank assembly (14). For example, the amount of torque required to rotate the crank assembly (14) is varied according to the rotational position of the crank assembly (14).

  • Patent number: 6930402
    Abstract: The present invention includes a power system that is designed to provide reliable electrical power to a facility, and specifically to a telecommunications facility. The system includes a number of proton exchange membranes (PEMs) adapted to provide DC power. The system is configured so that the PEMs receive fuel from a header that is supplied by a number of hydrogen generators. Storage tanks are also included to provide hydrogen to the header if the hydrogen generators fail. The hydrogen generators receive electricity initially from an array of photovoltaic panels. If the photovoltaic panels fail then AC power from a commercial utility is provided to the hydrogen generators. Finally, the system includes a number of super capacitors that are operable to maintain power during the time required to change between power sources.

  • Patent number: 6897576
    Abstract: A lightweight regenerative brake having a large braking force is provided. A regenerative brake 1 comprises a brake disc (10) and a pair of stators (20) to perform regenerative braking. This regenerative brake (1) reduces the heat generated in the brake disc (10), because a part of the kinetic energy of a railway car is regenerated by generation of electricity in a tertiary circuit of the power source side when the brake is applied, and consequently the amount of energy converted into heat energy is decreased. Compared to a conventional regenerative brake, this regenerative brake (1) enables the disc (10) to be made thinner and dispenses with a cooling device such as a fan. Accordingly, a small-sizes and lightweight brake having a large braking force can be constituted using this regenerative brake (1).

  • Patent number: 6753620
    Abstract: An engine generator includes an engine, a generator coaxially connected to the engine, a soundproofing case, and an exhaust muffler. The soundproofing case is divided into three, that is, a chamber to be cooled, and engine-side and generator-side air intake chambers on opposite sides of the chamber to be cooled. The chamber to be cooled houses the exhaust muffler and the majority of the engine and generator. Ventilation pathways are formed between an exhaust vent, which is provided in an upper part of the soundproofing case so as to open into the chamber to be cooled, and engine-side and generator-side outside air inlets which are provided in the soundproofing case so as to open into the engine-side and generator-side air intake chambers. Air is taken into the two air intake chambers from outside the soundproofing case via the two outside air inlets flows through the chamber to be cooled, and is discharged via the exhaust vent to the outside.

  • Patent number: 6750556
    Abstract: A generator embodying the invention comprises a removable fuel tank that is easily accessible, and may be easily removed from the generator. The generator includes a frame that supports an engine and the fuel tank. The fuel tank is removably interconnected to the frame with at least one quick release fastener. The quick release fastener may include a bolt, a pivoting tab, a clamp, or other similar quick release fasteners. Preferably, the quick release fastener may be engaged by hand, and does not require additional tooling. A fuel line between the fuel tank and the engine includes a quick disconnect attachment that prevents fuel flow and easily detaches the fuel tank from the engine. The fuel tank may be removed from the frame, taken to a gasoline station for refilling, and reattached to the generator for operation.
