Abstract: A method for social relationship oriented service processing, which comprises steps of: providing relationship data, searching for at least one first level social member from a first level social network according to the relationship data, forwarding a list of the first level social members to a server, and searching by the server for at least one second level social member from a second level social network according to the list and the relationship data.

Abstract: Resource management system is provided, implemented between a service bundle developer and provider and a service bundle user. A resource requirement determining device determines a system resource requirement for a service bundle provided by the service bundle developer and provider, and generates resource requirement information corresponding to the service bundle. A processor receives information of system resource utilization status from the service bundle user, determines whether available resource of the service bundle user is sufficient for the resource requirement of the service bundle, when the available resource of the service bundle user is insufficient, the processor generates a waiting queue, and adds the service bundle into the waiting queue. When available resource of the service bundle user is sufficient, the processor installs the service bundle specified in the waiting queue in the service user. A storage device stores the waiting queue and corresponding resource requirement information.

Abstract: A method and apparatus for implementing a smart management of a rechargeable battery provides the basic capabilities to measure the operating parameters of a rechargeable battery including voltage, temperature and current flow, used subsequently to control the flow of charge/discharge current and for determining the operation mode of the rechargeable battery. The control circuit includes a central processing unit to manage the charge/discharge operation and control the current flow; a trickle charger for slow charging; a cutoff switch to turn off the temperature detector; and an economizer switch to reduce power loss during normal charging of the battery. If the operating voltage of the battery is below a predetermined limit, the system automatically switches to a self-cutoff mode. Through a combination of the above control means, battery management for rechargeable batteries can be improved notably.

Abstract: A system and a method for handling laser-communication multiplexing in chaotic secure communications are disclosed. The messages to be multiplexed are encoded by chaotic laser signals of a transmitter system. The transmitted signals are then coupled to another chaotic system, the receiver system, so that the receiver and the transmitter are asymptotically synchronized. The decoding of the multiplexed messages encoded by chaotic behaviors is achieved by using a low-pass filter. This low-pass filter can effectively increase the fractal dimension of the chaotic system and enhance the periodicity of the transmitted time sequences, so that the multiplexed messages can be recovered.
