Abstract: A radar device includes a radar unit, a signal processing unit, a GPS receiver, and a storage unit. The signal processing unit acquires, for each target, a distance (R) to the target and a relative velocity (Veff) between the radar unit and the target when the radar unit is moving. The signal processing unit separately detects positions of a plurality of targets by using a separation algorithm in which a difference between the relative velocities (Veff) is used. When the radar unit is stopped, the signal processing unit corrects the position of each target detected when the radar unit has been moving, based on a current position of the radar unit stored in the storage unit, and identifies the positions of the plurality of targets.

Abstract: An information storage system and an information storage method allow necessary information to be stored in the proper amount with a simple operation for people to share the information. The system includes an input unit including a plurality of press-type switches each of which accepts input for an on-signal or an off-signal and a data server storing pieces of identification information each identifying a corresponding one of the switches and messages in association with each other and outputs, in response to input accepted by each of the switches, a corresponding one of the messages. The input unit transmits an on-signal or an off-signal and a piece of identification information to the data server. The data server receives the on-signal or the off-signal and the piece of identification information and extracts and outputs a message associated with the piece of identification information received together with the on-signal.

Abstract: Provided is a low-noise, long-life electromagnetic blower that has a simple, low-priced configuration and can realize two different outputs, high and low. When the electromagnetic blower is operated with low output, coils of an electromagnet are connected in series with each other, and an alternating current is supplied from an AC power source. When the blower is operated with high output, on the other hand, current is supplied to the one coil only. In the case where the electromagnetic blower is used for sewage disposal, the electromagnetic blower is operated with low output during aeration and with high output during reverse cleaning operation. Thereupon, the electromagnetic blower can operate with low noise during aeration, and the efficiency of reverse cleaning can be improved. In order to operate the electromagnetic blower with high output, moreover, the coils of the electromagnet may be connected in parallel with each other.
