Abstract: An electronic device includes at least one processor that identifies a cyclic change related to an arm swing of a user from a three-dimensional acceleration measured by a first measurer. The at least one processor defines a two-dimensional plane containing a plane of the arm swing of the user from the three-dimensional acceleration measured at a wrist of the user, detects the cyclic change as a motion on an arc centered at a shoulder of the user in the two-dimensional plane, and obtains an angle of the arm swing.

The at least one processor defines a two-dimensional plane containing a plane of the arm swing of the user from the three-dimensional acceleration measured at a wrist of the user, detects the cyclic change as a motion on an arc centered at a shoulder of the user in the two-dimensional plane, obtains, from the three-dimensional acceleration, a direction of a line segment connecting the wrist and the shoulder, and obtains a bending angle of an elbow of the user based on the line segment.

Abstract: Various models of brake parts (products) are produced with a mixedly transferring production system. The mixedly transferring production system includes a top line, a first production line, a second production line, and a third production line, a mixedly transferring depot, a part depot, and a set assembling line, and a product depot (mentioned in order of processing flow). Out of them, the first to third production lines, the mixedly transferring depot form the mixedly transferring block division type of production system. In addition, an averaging post and a production order plate (kanban) sorter are provided (mentioned in order of production command flow).

Abstract: A method of calibrating sensitivities of a plurality of pressure sensing cells are disposed at a passenger seat to detect presence of a vehicle passenger. The method is comprised of the following steps: pressing a presser against the passenger seat; detecting output signal levels of the sensing cells; and adjusting sensitivity of the pressure sensing cells according to the output signal levels while the presser is pressed against the seat.

Abstract: When a passenger distinguishment system is produced, after a seat cover is attached to a seat cushion while applying a tension to the seat cover, a conditioning operation is performed to lessen an adverse effect of the tension with respect to sensitivities of plural sensor cells that are disposed between the sensor cushion and the seat cover. The conditioning operation can disperse the tension of the seat cover, so that the sensor cells can detect loads applied to the seat accurately.
