Abstract: An operational condition of an outboard motor 1 is detected by an ECU 29, and transmitted via a communication unit 228, from a communication apparatus 283 to a base station 30. Antennas 32 and a cable 33 are arranged along an inner surface of an engine cover 12. The cable 33 is provided with a connector 34 for connecting the antenna 32 to a communication unit 28 and a GPS receiving circuit 31. The communication apparatus and the antennas are held floating in a case 351 which is filled with a gel, and the case 351 is fixed to the engine cover 12. A communication unit 28 is provided inside an engine cover 12. A housing portion 41 for a portable phone PH is provided pivoted about the cover 12 in such a manner that the portable phone is removable from the housing portion 41.

Abstract: An operating condition of an outboard motor 1 is detected by an ECU 3, and then, is transmitted to a remote monitoring apparatus 6 using a mobile phone 5. The condition data transmission is made by only access from the outboard motor 1 side, therefore, security can be secured. When confirming a failure based on the condition data, the remote monitoring apparatus 6 decides the cause of failure by troubleshooting, and then, give information about measures to a boat 2 equipped with the outboard motor 1. Troubleshooting is carried out by acquiring a program from a server of maker, and the cause of failure is transmitted to the server so as to be stored as user information. The remote monitoring apparatus 6 orders necessary maintenance parts so as to improve quickness of maintenance.

Abstract: An electromagnetic wave radiation control apparatus includes an antenna, a modulator, an amplifier, and a radiation control unit. The modulator modulates a carrier wave based on a transmission signal to output a modulated signal, wherein the modulator stops the output of the modulated signal in response to a power off command. The amplifier amplifies the modulated signal such that the amplified signal is radiated as electromagnetic wave from the antenna, when the modulated signal is outputted from the modulator. The radiation control unit generates the power off command to the modulator, when radiation of electromagnetic wave in a current radiation direction of the antenna is inhibited, or when a level of a reception signal by the antenna is equal to or lower than a predetermined minimum level.

Abstract: A robot is provided to run so that a trace of the robot efficiently covers a given area according to the detection of a boundary of the area. A spiral pattern running, wherein a radius of the spiral is gradually increased, is started at a desired location in the area and is paused upon the detection of a boundary wall by sensors. Then, a random pattern running, which includes turning to depart from the wall and running forward, is conducted. After the turning has been repeated a predetermined number of times through simulations, the spiral pattern running is resumed at a location spaced from the last turning spot by a predetermined distance or a predetermined length of running time.

Abstract: When a difference between sums of distance measurements detected by the left and right side sensors of a robot 1 is greater than a reference value, the turn is performed to avoid an obstacle ahead. If the direction of the current turn is opposite to that of the previous turn, since the angle of turning in the current turn is decreased, the robot 1 prevents redundant turn and can thus run through between obstacles. If the (swivel) turn has been repeated a given number of times in a zigzag movement, an escape motion from the deadlock state is commenced which includes a backward running of a predetermined distance and a (swivel) turn following the backward running.
