An AC/DC/AC power converter is constructed without using any electrolytic capacitor, such that it is more compact, durable and reliable. This converter only required a small capacitance for its DC link and this capacitor can be easily obtainable with other types of capacitors such as film or ceramic type. The system further includes means to disconnect both input and output to this DC bus capacitor. A controller capable of fast monitoring the DC bus voltage is also able of quickly disconnecting the capacitor out of either input or output energy path to prevent the capacitor from being charged to over-voltage. The controller also possesses capability of re-connecting the disrupted energy path once the DC bus voltage returns to normal.

An air manifold adapted for attaching to an air fill opening in a side of plastic, polymer balloons and receiving compressed air therein. The air manifold includes a hollow manifold body with a plurality of outwardly extending manifold air ports attached to and spaced around an outer circumference of the manifold body. The air ports are adapted for releasable or permanent attachment to the air fill openings in the side of the balloons. The manifold body also includes an air tube. The air tube has one end attached to and in fluid communication with the manifold body. An opposite end of the air tube is adapted for receiving the compressed air therethrough and into the manifold body. When the compressed air is received through the air tube and into the manifold body, the balloons attached to the manifold air ports are inflated for forming a balloon cluster around the manifold body thus providing an attractive and decorative display.

A tail including a drag chute released by a fish strike, attachable to the same head, is also disclosed. A dive wing, attachable to the removable tails, is also disclosed. Tails can include bait scent chambers and release holes and water jets to attract fish. A kit with combinations of heads, tails, dive wings, and other parts and accessories is also disclosed.

The assembly includes a system for holding a product and a protection device for protecting the system. The protection device comprises a cap mounted on the system so as to at least partly cover it and at least one releasing means for releasing the system. The releasing means includes a retaining means for retaining the system relative to the cap and an actuating means for actuating the retaining means in order to disconnect the system and the protection device. The retaining means is provided on an inner face of the releasing means, the actuating means being provided on an outer face of the releasing means, on the opposite side from the inner face. The releasing means may be a rocker system and the protection device may cover at least 90% of the packaging system.

The invention relates to power networks, and in particular to a battery energy source arrangement and voltage source converter system in such network. The battery energy source arrangement includes battery energy storage, having one or more parallel-connected battery strings and a mechanism for connecting a voltage of the battery strings to a load. The battery energy source arrangement further includes battery string voltage adapter devices connected in series with respective ones of the one or more battery strings wherein the battery string voltage adapter devices are designed to handle only a fraction of the voltage handled by the battery strings.

A mounting bracket may include a base plate, at least one stationary clip disposed on the base plate, a push releasing plate disposed in spaced apart relation to the at least one stationary clip, and at least one movable clip operatively coupled to and movable with the push releasing plate. The stationary clip or clips and movable clip or clips are disposed and configured to mate with cavities in respective ends of a pump when the push releasing plate is in a non-pivoted position.

A device and method for operating automotive battery system relays and related switches. By aligning a magnetic field with a direction of current flow in a contact plate disposed between magnets that are producing the field, a generated Lorentz force can be used to promote arc extinguishing during a relay opening sequence, while simultaneously reducing the tendency of the Lorentz forces to interfere with the operation of a solenoid or other switch-activating mechanisms. By using a rotary-based mechanism to establish contact between a contact plate and current-carrying terminals, the likelihood of inadvertent opening of the relay is reduced. Such devices and methods may be used in conjunction with hybrid-powered and electric-powered vehicles.
