Abstract: The present invention discloses a battery pack and an electric tool that comprises such a battery pack. A battery pack comprises: one or a plurality of battery cells, a circuit board, which is located inside the housing of the battery pack, a lead board, which is connected to the electrode terminals of one or the plurality of battery cells, and a metal plate, which is arranged on said circuit board and electrically connects said lead board to the circuit in said circuit board, wherein said metal plate is fixed to said circuit board using the surface mounting technology.

Abstract: A method (and apparatus) for adapting an input parameter, for dynamically invoke the target Web services, and for adapting output results, the method including: receiving an invocation request including an input parameter in a first format; retrieving MetaWSDL (Meta Web Service Description Language) wherein said MetaWSDL includes a universal XML (eXtended Markup Language) representation which includes semantic information of a Web service method signature; invoking a MetaWSDL processor to adapt the input parameter to a second format using the retrieved MetaWSDL; dynamically invoking the target Web services using the adapted parameter in the second format; and adapting the output result in a first format to a second format using the MetaWSDL.

Abstract: Three-dimensional parameters of a tire are measured dynamically in a non-contact way using laser vision technology. Two laser vision sensors are used, which are calibrated and then used for practical measurement. The system offers a wide measuring range, high accuracy and high efficiency, even though the tire is moving, and it minimizes the size of the measuring apparatus, and reduces the cost of the apparatus.
