Abstract: A power generator management system comprises a plurality of power generators, and an information processing apparatus configured to process information acquired from the plurality of power generators. Each power generator comprises: a detection unit configured to detect a remaining fuel amount in a fuel tank of the power generator; a position acquisition unit configured to acquire position information of the power generator; a state acquisition unit configured to acquire information representing an operating state of the power generator; and a communication unit configured to transmit the remaining fuel amount, the position information, and information representing the operating state to the information processing apparatus, and the information processing apparatus comprises a processing unit configured to acquire a margin level of power supply in each of the plurality of power generators and provide a result of the acquisition.

Abstract: To make it possible to correct a current position detected by an autonomous traveling work machine to the correct position with a simple configuration. A robot lawn mower includes a first position detecting unit for detecting a current position by using odometry and a second position detecting unit for detecting a current position by using an image capture. When position detection accuracy of both of the first and second position detecting units decreases to less than or equal to a predetermined value, the robot lawn mower is controlled to travel to either of zones Z1 and Z2 in which the position detection accuracy of the second position detecting unit is relatively high, and when the robot lawn mower moves to either of the zones Z1 and Z2, a current position used for autonomous traveling is corrected to the current position detected by the second position detecting unit.

Abstract: An anti-theft apparatus for an outboard motor that can be mounted on a boat, comprising a comparison unit configured to compare a vibration of the outboard motor with a vibration of a portion of the boat other than the outboard motor, and a notification unit configured to make a predetermined notification based on a comparison result by the comparison unit.

Abstract: A lawn mower includes a cutter blade that cuts grass; a body portion including a housing containing the cutter blade, and a grass clippings discharge passage that discharge grass clippings cut by the cutter blade from the housing; a grass clippings container detachably attached to the body portion, and a slide device. The grass clippings discharge passage includes an upstream opening connected to the housing, and a downstream opening for ejecting grass clippings to outside of the body portion. The grass clippings container includes an opening opened toward the body portion and connected to the body portion, an end surface facing the opening, and a side surface extending from the opening to the end surface. The slide device adjusts a distance between the downstream opening of the grass clippings discharge passage and the end surface of the grass clipping container.

Abstract: A lawn mower includes a cutter blade that cuts grass, a body portion including a housing containing the cutter blade, and a grass clippings discharge passage that discharges grass clippings cut by the cutler blade from the housing, a grass clippings container that contain grass clippings, and an opening degree adjust valve. The grass clippings discharge passage includes an upstream opening connected to the housing, and a downstream opening for ejecting grass clippings to outside of the body portion. The opening degree adjust valve is provided at the downstream opening of the grass clippings discharge passage and adjusts an opening degree of the downstream opening.

Abstract: A lawn mower includes: a rotation shaft coupled to a power source and extending in an approximately vertical direction a blade configured to rotate integrally with the rotation shaft and a housing having a downward opening and accommodating the blade such that the blade is rotatable; and a maintenance tool provided on the housing, the maintenance tool being contactable with the blade from the above. A cutting portion of the blade is capable of moving between a maintenance position at which the cutting portion is contactable with the maintenance tool and an operating position at which the cutting portion mows a lawn.
