In an air conditioner for a hybrid vehicle, when a residual charging degree of a battery becomes equal to or lower than a target degree, the electrical motor generator is driven by a vehicle engine so that the battery is charged through the electrical motor generator. When the engine is driven, the target degree of the battery is set higher than that when the engine is stopped so that a charging operation tends to be required while the engine is driven. Accordingly, the frequency for starting the engine only for charging the battery is reduced.

A passive identification system for shipping containers. The shipping containers contain passive identification devices that are interrogated by separate on-board location trackers (OBLT) located in places where shipping containers are expected to pass in proximity to during the shipping and transport process. The OBLTs contain an active transmitter and GPS device. After the OBLT interrogates the passive identification device on a shipping container, the OBLT generates a geo-word comprised of the container identification, the GPS location of the OBLT, and a time stamp, and transmits the geo-word to a receiving station for tracking and/or security purposes. The receiving station has manifest information regarding the shipping containers stored in memory. In this manner, the receiving station can compare the geo-word to the expected shipping locations and expected times for the shipping container to determine if the shipping container is lost, misplaced, or off-schedule.

The invention provides a privacy protection method for protecting information and position safety of soldiers in a field battle environment for solving certain problems. Personal information such as physical signs of the soldiers is protected by establishing safety paths between adjacent nodes through area keys. The method includes the steps of 1 a key initialization stage, 2 a network initialization stage and 3 a data transmission stage. In the key initialization stage, a whole network is divided into smaller areas, a key pool is also divided into subsets corresponding to the areas, and the adjacent nodes directly share a key to form one safety path. In the network initialization stage, in the multi-hop routing process of a data package from a source node to a base station, for achieving path-finding to the base station, a dynamic routing table needs to be established in each node. In the data transmission stage, a directional random routing scheme is introduced, in the scheme, the position of a the real source node and the position of the real base station are hidden trough a proxy source node and a pseudo base station respectively, a certain amount of false packages can be generated when the proxy source node transmits data, so that attackers are misled, and the time for the attackers to find out the positions of the soldiers is prolonged.

A method for controlling the configuration of configuration parameter set of the remote device uses a unique identifier to identify the current configuration parameter set of the remote device. The identifier varies with the content of the configuration parameter set. So the remote device transmits it's own identifier of the configuration parameter set to the configuration management server and compares it with the identifier of the configuration parameter set of the remote device stored in the configuration management server after starting. When the identifiers are not same, the configuration management server updates the configuration of the remote device. Otherwise the remote device operates with the original configuration. In addition, a corresponding device for controlling the configuration of the configuration parameter set of the remote device is provided. In the present invention, because the interaction of the identifiers reduces the management flow of the network, the load of the management information in the network and the management system is efficiently lessened. Thereby the cost of the operators for managing the remote device is reduced and the reliability of the configuration also can be ensured.
