Abstract: An electric vehicle which travels by driving actuators includes: a monitor unit which monitors external environment or internal environment of the electric vehicle; an alarm unit which outputs, based on monitoring information obtained by the monitoring unit, a vibration velocity signal indicating velocity which changes in a cycle; a travel information generation unit which calculates a target travel velocity based on a steering direction and a control input provided by an operator of the electric vehicle, and generates travel control information for controlling the actuators based on the target travel velocity; and a control unit which controls the actuators based on the travel control information. The travel information generation unit regenerates the travel control information by adding the vibration velocity signal to the target travel velocity upon receiving the vibration velocity signal.

The second needle portion has a distal end having the liquid pass opening, a base portion connected to the needle base portion, and an intermediate portion connecting the distal end and the base portion.

Abstract: In a bed combination method of forming a bed on which a person lies by combining a wheelchair with a recess part of a bed base portion of a bed main portion, a posture of a seat portion of the wheelchair is changed from a chair posture to a tilt posture where the seat portion is inclined in such a manner that a position of a footrest is higher than the base portion by a tilt action while a shape of the seat portion is maintained as a chair shape, and then, the wheelchair is moved to the recess part of the base portion, and the seat portion is changed from the tilt posture to a non-tilt posture.
