Abstract: Methods for sending interactive promotion information used between a portable device and a multimedia device are provided. The multimedia device stores a plurality of multimedia information and corresponding promotion information. The portable device is connected to the multimedia device of a specific place through a communication network. The portable device obtains a first certificate corresponding to a product of the specific place, wherein the first certificate includes consumer behavior information of the product and connection information for the multimedia device. The portable device logs into the multimedia device through the first certificate and the communication network. After successfully logging into the multimedia device, the portable device generates an operation user interface for operating the multimedia device to select one of the multimedia information to play.

Abstract: A temperature moderation system with temperature difference considerations between indoors and outdoors for facilitating an air conditioner in operation control, includes an indoor unit and an outdoor unit connected with each other. The outdoor unit has an outdoor temperature detection element. The indoor unit has a processor for generating and sending a target temperature to the air conditioner for operation control. The target temperature is one selected from the indoor setting temperature and a pre-set temperature; according to which temperature is closest to the outdoor temperature.

Abstract: A system for product recommendation comprises several automatic service equipments which are mutually linked via a communication network. Each of the automatic service equipments obtains data of other user groups, data of other product groups and other, relation matrixes from other automatic service equipments. Each of the automatic service equipments integrates data of other user groups into data of local user groups stored in itself, and also integrates data of other product groups into data of local product groups stored in itself. Each of the automatic service equipments revises a local relation matrix stored in itself, such that the revised local relation matrix records correlation coefficients between the integrated local user groups and the integrated local product groups. Each of the automatic service equipments performs product recommendation according to the integrated data and input data received through an input device.
