A system and method for transferring money by use of a prepaid card account is disclosed wherein two cards are issued to the user accountholder, one of which is provided to another user, and either user may add value to the prepaid account so that the other user may use the card and that value in a financial transaction.

A handling device is provided for handling a burner of a stationary gas turbine during assembly and disassembly, including a base body having at least one contact surface designed to contact a rear end surface of a burner, fixing means for fixing the base body to the rear end surface of the burner, and two arms fixed to and protruding from the base body to different sides of the contact surface, wherein each arm is provided with receiving means, which are designed for removably receiving a fixing component of a lifting appliance and which are spaced apart from each other in the longitudinal direction of a burner during its handling.

The invention discloses a random optimization scheduling method considering flexibility for a wind power-containing electric power system. According to the method, the random fluctuation of the net load and the operation characteristics of the source load storage are comprehensively considered, a power system flexibility requirement model is established by utilizing Gaussian mixture distribution,a multi-type flexibility resource supply model is constructed, and then a power system operation flexibility probability balance model is constructed. Risk loss brought to the power system due to insufficient flexibility is measured by utilizing conditional risk values, then system power balance constraints, operation flexibility constraints and equipment operation constraints are considered, a wind power-containing power system random optimization scheduling model considering flexibility is constructed, and system operation economy and flexibility are considered at the same time.

The invention discloses a multifunctional mattress, comprising a mattress cover and a mattress body arranged in the mattress cover, wherein the mattress body comprises a cuboid-shaped frame and a trampoline cushion; the four sides of the top of the frame are respectively connected with the four sides of the trampoline cushion by a transversal spring; an upper support plate, a lower support plate and a bottom plate which are parallel to one another are sequentially arranged under the trampoline cushion from top to bottom; the upper support plate and the lower support plate are embedded in the frame in a way of sliding along a vertical direction, a plurality of longitudinal springs are arranged between the upper support plate and the lower support plate, and the two ends of the longitudinal springs are respectively fixed to the upper support plate and the lower support plate; the bottom plate is fixed at the bottom of the frame and is provided with an electric telescopic pole, and the top end of the electric telescopic pole is fixed at the bottom of the lower support plate; the upper support plate consists of four layers from bottom to top, i.e., a board, and a sponge cushion, a cotton cushion and a cotton cloth pad which are sequentially fixed on the board. According to the multifunctional mattress, not only can the elasticity of the mattress be adjusted so as to meet the requirements of different people on the elasticity, but also can be used as a trampoline for entertainment of children.
