The present invention provides a service processing method and system in a content distribution network of an interactive network TV. The service processing method includes the following steps: a service processing manager receiving and processing a service acquisition request of a service requesting device, and allocating service processing agent(s) for the service requesting device according to a load balance strategy; and the service processing agent(s) providing service for the service requesting device. The service processing system includes a service processing manager and service processing agents, wherein the service processing agents are adapted to provide service for a service requesting device, and the service processing manager is adapted to receive and process a service acquisition request of a service requesting device, and allocate a service processing agent(s) for the service requesting device according to a load balance strategy. The present invention deconcentrates the pressure of the service processing system, prevents the system from probable breaking down due to heavy load, and thereby can improve the stability of the operation of the system.

The present invention is directed to nanodiamond (ND) surface coatings and methods of making same. Such coatings are formed by a covalent linkage of ND crystals to a particular surface via linker species. The methods described herein overcome many of the limitations of the prior art in that they can be performed with standard wet chemistry (i.e., solution-based) methods, thereby permitting low temperature processing. Additionally, such coatings can potentially be applied on a large scale and for coating large areas of a variety of different substrates.

Embodiments of the present disclosure disclose a method for controlling power consumption of an embedded system. The method obtains a data transmission index that is between a bus module and a bus, compares the obtained data transmission index with a preset numeric value range, and adjusts an operation frequency or an operation voltage of the bus module when the data transmission index exceeds the preset numeric value range. Embodiments of the present disclosure further provide a system and a relevant apparatus for controlling power consumption of the embedded system. In comparison with the conventional art, embodiments of the present disclosure effectively monitor the load of the bus module, and adjust the operation parameters of the module according to the monitoring result to enable the module to operate under proper operation parameters and to thereby reduce unnecessary power consumption.
