Characters are easily input using a direction indicating device.The device provides a direction indicating device which outputs a rotated direction of lowering, or the direction inclination and its strength, a display device, a key input means, a memory that stores a plurality of character sets, and a control means which selects characters a character set and characters comprising this character set which are stored in memory according to the output of the direction indicating device, and displays them on the display device, and which accepts the output of the direction indicating device as circumferential position information, and selects a specified character from a chart of characters that associates the previously provided position information with the output of the direction indicating device.

Within a moving robot of narrow footprint, having quick traveling performance on a plane-surface, as well as, anti-tumbling function, and further being suitable for operations under coexistence with a human being, being able to travel coping with traveling situations on a level difference, etc.: in front and rear of main driving wheels 2 and 3, each being controlled through the inverted pendulum control, are disposed supporting legs 4 and 5, tips of which can be lifted up and down, wherein the tips of the supporting legs 4 and 5 are positioned to keep a predetermined distance between a traveling surface, when running on the inverted two-wheels travel, and the supporting legs 4 and 5 are fixed or either one in the fall-down direction is thrust out into the fall-down direction, so as to protect it from falling down. Further, upon the basis of detection information of floor-surface distance sensors 4e and 5e and side-surface distance sensor 4f, 4g, 5f and 5g, which are provided at the tips of the supporting legs 4 and 5, the robot senses an existence of a level difference and / or an inclined surface, so as to let the supporting legs to escape from the level difference and / or the inclined surface, and holds the position of gravity center thereof, stably, through other one of the supporting legs, being landed on the ground, and the main driving wheels 2 and 3; thereby enabling to travel over the level difference and the inclines surface.

A headrest apparatus for vehicle seats. The headrest apparatus includes coupling holders, a support, a headrest, and an actuating unit. The headrest apparatus further includes a connector body mounted outside any one of the coupling holders, and configured to have guide rails that extend from the connector body in the ascending and descending direction of the support; a slider coupled to the connector body so as to be moved along the guide rails; and connectors configured to be respectively mounted to a lower end of the support and the slider, to be coupled to or separated from each other according to the ascent and descent of the support, and to be respectively connected with the power line, which is connected to the actuating unit of the headrest, and the power line, which is connected to the power supply unit of the vehicle via the seat main body.

A system and method is disclosed for controlling a robot having at least two legs, the robot falling down from an upright posture and the robot located near a plurality of surrounding objects. A plurality of predicted fall directions of the robot are determined, where each predicted fall direction is associated with a foot placement strategy, such as taking a step, for avoiding the surrounding objects. The degree to which each predicted fall direction avoids the surrounding objects is determined. A best strategy is selected from the various foot placement strategies based on the degree to which the associated fall direction avoids the surrounding objects. The robot is controlled to implement this best strategy.
