Abstract: Disclosed is a seat including: sensors which includes a first cushion sensor provided at a seat cushion in a position corresponding to buttocks of an occupant, a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor, a first back sensor provided at a seat back and located in a lower position thereof, and a second back sensor provided at the seat back and located above the first back sensor; and a controller connected to the sensors and thereby allowed to acquire pressure values from the respective sensors. The controller is configured to identify the motion of the occupant based on outputs of at least two sensors of the first cushion sensor, the second cushion sensor, the first back sensor, and the second back sensor.

Abstract: A seat includes a seat body and a sensor configured to acquired information on an occupant seated on the seat body. The seat includes a coating as a location marker that marks a location of the sensor to render the location visually recognizable from outside the seat body.

Abstract: Provided is a method of creating a longitudinal section along an arbitrary line from three-dimensional point group data of terrain or a structure, and a survey data processing device and a survey system for the same. The method includes (a): setting an arbitrary longitudinal section creation line by sequentially designating a plurality of interval designation points on an X-Y plane of three-dimensional point group data (X, Y, Z), (b): projecting a Z point surveyed between a start point and an end point of a certain interval among a plurality of intervals defined by the interval designation points, onto a vertical virtual plane including the longitudinal section creation line, corresponding to (X, Y) coordinates of the longitudinal section creation line, and (c): performing the step (b) for all of the intervals.
