Abstract: The invention provides an online bargaining system, which includes an online bargaining platform for allowing a client to send a bargaining service request on goods for sale in a near-end physical store to a cloud server, such that the cloud server may interact with the client through the online bargaining platform to process the bargaining service request. The invention further provides an online goods promotion system for allowing the client to interact with the cloud server through an online goods promotion platform and take part in goods promotions in the near-end physical store. The invention allows consumers when shopping in a physical store to have online interactions of real-time price bargaining and promotions on goods for sale with a business owning the physical store, making the physical store become a competitive advantage for both the business and consumers. The invention may further combine reality games with goods promotions and thus bring more fun when the consumers interact with the store.

Abstract: Disclosure is related to a method for transmitting data, and the method is applicable to a mobile storage apparatus. The mobile storage apparatus provides multiple electronic devices to wirelessly access the files stored in the apparatus. The apparatus determines a scheme to segment the files to be sent according to the files' types, sizes and the order of the connected devices. The files are segmented into multiple sections before the transmission. A power management unit may turn off a communication unit within the apparatus when the transmission procedure enters an idle state. When the jobs in the electronic devices have been completed, the communication unit is again turned on for transmitting next segment until the files are completely transmitted. The invention achieves efficient transmission in a power-saving mode.
