  • Patent number: 7289881
    Abstract: A robot includes a robot sensor for sensing abnormality around the robot, a moving portion for moving the robot main body, and a movement control unit for controlling the moving portion so that the robot main body is moved to a destination determined according to the information sensed by a fixed-position sensor fixed to a predetermined position outside the robot. The moving destination may be determined by the total control unit of the robot main body according to the information from the fixed-position sensors or by a center communicating with the robot according to the information from the fixed-position sensors. Since abnormality is sensed by the fixed-position sensors together with the robot sensor, the fixed-position sensors may have low accuracy obtained at a low cost.

  • Patent number: 7109875
    Abstract: In a sensor network system, a communications network connects a set of sensors to a server collectively managing the set of sensors. First, the sensor-managing server acquires remaining drive times of batteries in the sensors, and specifies a target remaining drive time. The server then controls the operation of the sensors so that the remaining drive times of the batteries in the sensors are substantially equal to the target remaining drive time. This reduces the maintenance workload for a system manager, especially, in the recharging of the sensor batteries.

  • Patent number: 6956478
    Abstract: In a case where an intruder is detected in a house, a detection signal is outputted from a home security communication device, and is notified to a monitor center through an in-area communication management device by a wireless connection. The monitor center notifies a portable telephone owned by a resident of the house that the intruder exists in the house and also notifies houses to in the area that the intruder exists in the house.

  • Publication number: 20050014486
    Abstract: The object of this invention is to collect a data without using a specialized system such as sensor terminals and provide a data to a terminal device. The information provision system according to this invention is provided with fixed data transmitters and sensing data transmitters. When terminal device 23 moves into a predetermined space (sensor field), the terminal device receives a predetermined fixed data from the fixed data transmitter, and/or a sensing data obtained by sensing from the sensing data transmitter. The terminal device then transmits these received data to data processing server 21 along with a process request via a network. The data processing server can execute a processing based on these received data and the process request, and generate a process data in order to provide for the terminal device.
