Abstract: An energy conversion device may include a shaft including a first portion and a second portion wherein the first portion of the shaft is configured to rotate relative to the second portion of the shaft. A rotor may be coupled to the first portion of the shaft and a stator may be coupled to the second portion of the shaft. A first one-way bearing may be coupled to the first portion of the shaft and configured to transfer rotational input to the first portion of the shaft in a first direction. A second one-way bearing may be coupled to the second portion of the shaft and configured to transfer rotational input to the second portion of the shaft in a second direction opposite the first direction.

Abstract: A new and improved serving utensil is provided. The serving utensil may include a pair of elongated arms integrally formed together, or joined together by a hinge. Each elongated arm may comprise an elongated member, having an upper edge and an opposing lower edge, integrally connected to a gripping portion at its distal end and handle portions extending upwardly from the elongated member and having a concave or curvilinear shape. The serving utensil may further include a pair of guard members integrally connected to, and extending perpendicularly outward from, the pair of elongated arms.

Abstract: A data push service method and system are provided. The service data push method includes: providing a device with data push information regarding service data to be pushed to at least one device; and pushing the service data to the device when receiving a data push service request from the at least one device. Accordingly, the server does not need to maintain and manage information of the at least one device.

Abstract: Structure of driving unit in a drum type washing machine including a tub mounted inside of a cabinet, a drum mounted inside of the tub, a shaft connected to the drum mounted inside of the tub for transmission of a driving force from a motor to the drum, a front bearing and a rear bearing mounted on an outer circumference of the shaft at opposite end portions thereof respectively, a bearing housing built in a central portion of a rear wall of the tub for supporting the front bearing, a rotor composing the motor together with the rotor, and coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor to compose the motor together with the rotor, a connector serration coupled to the outer circumference of the shaft in front of the rear bearing and fixed to the rotor, for transmission of a rotating power from the rotor to the shaft, and a bearing bracket fixed to the rear wall of the tub to cover an outside of the rotor and support the rear bearing, thereby reducing noise,
