An apparatus and method for electrostatic spray deposition of small targets, such as medical devices like stents. The apparatus includes a target holder which applies a first electrical potential to the target, and an electrostatic dispensing nozzle which applies a second potential sufficient to attract the coating fluid from the nozzle toward the target. Because the entire dispensing nozzle is conductive, the coating fluid may receive a greater charge than may be obtained with internal electrode-type nozzles. Electrostatic attraction of the coating fluid to the target is enhanced by the combination of higher charge density imparted to the coating fluid by the conductive nozzle, and application of a momentary voltage spike to the target to provide consistent conductivity between the target and its holder, thereby ensuring the target is presents the full first potential applied to the holder. The voltage spike may also be used independently of the conductive nozzle.

The current multi-base station cooperative communication technology could only provide one type of cooperative communication fixedly, and this results in that either the amount of data exchange between the base stations is huge and the latency is increased, or the optimum gain can not be obtained. To address this problem, the invention proposes a switching technology for collaboration type in multi-sector cooperative communication. The base station equipment dominating the sector determines one or more cooperating sectors of the mobile terminal, determines the type of the multi-sector cooperative communication provided cooperatively with said one or more cooperating sectors, based on information of said one or more cooperating sectors according to predefined rules, and cooperates with said one or more cooperating sectors and provides, for the mobile terminal, the multi-sector cooperative communication of the corresponding determined type. According to the invention, high speed exchange of the complete channel information and data are conducted between the same-cell sectors, and the cooperative gain is increased; none or few of data backhaul is conducted between the different-cell sectors, which results in decreased backhaul latency of the cooperating information, and increased throughput of the user at sector edge and system performance.
