A robotic surgical system according to this disclosure includes a controller configured to execute processing of displaying, on a display, a graphical user interface including a distance indication representing a distance from a preset reference point to a predetermined portion of a surgical instrument while the surgical instrument is being moved to a desired position by an operation input.

A transmission operatively connected to a turbine engine of an aircraft to selectively transfer power from a first pressure spool of the turbine engine to a second pressure spool of the turbine engine and to power an accessory. The transmission is configured to selectively operate in one of a first configuration and a second configuration. The first configuration transfers power from the turbine engine to the accessory and the second configuration transfers power from the first pressure spool to the second pressure spool.

A hydraulic rotating machine 1 according to one embodiment includes: a rotating shaft 2, which extends along a rotational axis 20; a housing 5 including cylinder bores 50, which are radially located around the rotational axis 20; and a drum 4, which moves pistons 61 in a reciprocating manner by rotating together with the rotating shaft 2, the pistons 61 being located within the respective cylinder bores 50. The hydraulic rotating machine 1 further includes: an eccentric amount adjuster 3, which changes an eccentric amount of the drum 4, the eccentric amount being a distance from the rotational axis 20 to a center of the drum 4; a rotary encoder 84, which detects a rotational angle of the rotating shaft 2; and at least one linear encoder that detects, on a straight line that perpendicularly intersects the rotational axis 20, a position of a particular circle that is concentric with the drum 4.

A hydrogen aircraft utilizes hydrogen as fuel for a power unit. The hydrogen aircraft includes target piping and a cooling device. The target piping is piping for transportation of liquid hydrogen, and has a stagnation period during which liquid hydrogen does not substantially flow while the hydrogen aircraft is in operation. The cooling device cools the target piping.
