A wind turbine configuration is constructed with a power cable having an electrical conductor with a plurality of copper clad aluminum strands that are highly flexible. The power cable includes a composite insulator including an insulating material surrounding the electrical conductor and a jacket surrounding the insulating material. The wind turbine configuration includes a wind turbine having a tower with a top and a bottom. A generator is located near the top of the tower, and a transformer is located outside of the wind turbine. A plurality of rotor blades is connected to the generator. The power cable electrically connects the generator of the wind turbine to the transformer. A method includes electrically connecting the power cable to a generator of the wind turbine and to a transformer conveying power supplied by the generator to a switchyard.

Storage system(s) for storing data in physical storage in a recurring manner, method(s) of operating thereof, and corresponding computer program product(s). For example, a possible method can include: upon start of a storage recurrence, destaging dirty data which had been accommodated in the cache memory prior to the start of said storage recurrence thus giving rise to destaged data group, wherein destaging is provided with no overwriting of at least superseded data destaged before starting said storage recurrence whilst enabling retaining metadata indicative of location of said superseded data in the physical storage space; accommodating data obtained in said cache memory subsequent to the start of said storage recurrence whilst preventing said data from being destaged during said storage recurrence, thus giving rise to accommodated data group; and registering a point-in-time indicative of successful destaging of the destaged data group, thereby providing an order-preservation consistency indication corresponding to said recurrence.

A drum pedal sensing system may include a base, a foot board, a pedestal, a beater, beater stem, and beater holder operatively connected to the foot board, a sensor holder, and a sensor fixedly coupled to the sensor holder. The beater holder may include a sensing surface that may rotate as the foot board is depressed and that may remain a substantially constant distance from the sensor as the sensing surface rotates. Additionally, the system may include a microprocessor operatively coupled to the sensor that receives signals from the sensor corresponding to motion of the sensing surface. Based on sensed changes such as changes in position, velocity, or acceleration, the microprocessor may determine whether the beater has contacted a drum face and, if so, may send an output signal to a stomp box, drum brain or similar element, with the amplitude of this output signal proportional to strength of the hit.

A drum pedal assembly for connecting a first pedal to a support holding a beater arm may include a telescoping transmission shaft having yokes attached to shaft ends, yokes having bosses, universal joints rotatably attached to bosses and using trunnions, second yokes having bosses attached to universal joints using additional trunnions. The second yokes may rotatably attach a drive assembly rotatably attached to first pedal and an attachment arbor attached to beater arm to facilitate rotation of beater arm when first pedal is depressed. Configuration of assembly, including that of universal joints, may help reduce backlash or vibration in assembly.

A drum pedal, having a drive assembly supported by a pedestal, may include a drive shaft, a rotatably adjustable drive ring having an arm, and a rotatably adjustable beater ring. A link may connect a foot board with the arm. A beater may have a stem affixed to the beater ring. The beater may be actuated to a forward position when the foot board is depressed. The foot board may be biased toward a raised position and the beater may be biased toward a rearward position. In another aspect, a drum pedal may have a drive assembly with a cam, having a slope, mounted on a drive shaft. The cam and a spring may cooperate to bias a cam follower toward a predetermined rest position. An adjuster may be provided to easily change the tension of the spring. In still another aspect, a drum pedal may have a drumward clamp including a shaft, a rotatable arm, and a torsion spring for biasing the arm toward locking with a drum rim. The arm may be unlocked by rotating a lever connected to the shaft.

There is provided a storage control grid capable of controlling at least one service provided in the storage system and a method of operating thereof. The storage control grid comprises at least one service dispatcher operatively coupled to at least one service requestor and to a plurality of service providers. The method comprises requesting by service requester a service, thus giving rise to at least one service request; enabling, using said at least one service dispatcher, delivery of the service request to at least one service provider among said plurality of service providers, said service provider configured to provide said at least one service, wherein the delivery is enabled in accordance with data comprised in a service data structure handled by said at least one service dispatcher and indicative, at least, of association between said at least one service and service providers among said plurality of service providers.

Storage system(s) for providing storing data in physical storage in a recurring manner, method(s) of operating thereof, and corresponding computer program product(s). For example, a possible method can include for each recurrence: generating a snapshot of at least one logical volume; destaging all data corresponding to the snapshot which was accommodated in the cache memory prior to a time of generating the snapshot and which was dirty at the time of generating said snapshot, thus giving rise to destaged data group; and after the destaged data group has been successfully destaged, registering an indication that the snapshot is associated with an order preservation consistency condition for the at least one logical volume, thus giving rise to a consistency snapshot.
