Title: Navigation device, method thereof, and provided medium
Inventor: YOSHIDA KAZUFUMI
IPC: G09B29/10
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To easily and surely correct a present position by arranging a correction means correcting the present position to a second present position computed according to a predetermined rule when correction of the present position deviated from the route is directed. SOLUTION: A searching means searches a route to a destination, while a detecting means detects a first present position. A present position display means displays a detected first present position on a map, while a directing means directs correction of a deviation in the first present position from the route. In this case, a computing means computes an imaginary second present position according to a predetermined rule. A correcting means corrects the first present position displayed on the map to the second present position computed by the computing means. For example, if a mark M representing the present position is deviated from the route, a position nearest to the present position on the route is computed as a correction position, and the mark M position is changed to the computed correction position.  In this way, a user can easily carry out correction processing even in a moving vehicle.

Abstract: PURPOSE:To prevent plaque from being left so as to be able to easily confirm a place with which the top ends of brushing hairs comes into contact by providing both a main body which can hold a toothbrush and a lightening device by which light can be applied near the place where the hairs are planted on the toothbrush. CONSTITUTION:After a toothbrush 7 is held in a main body 1 and this main body is held by the hand, a switching knob 2 is operated. The toothbrush 7 thus starts a shuttle motion and the light of a lightening device 5 is applied to a place 8 where hairs are planted. For that reason, since a place with which top ends 12 of the brushing hairs comes into contact on the surface of teeth is brightly lightened by only touching the top ends 12 of the brushing hairs of the toothbrush 7 on the teeth and can be precisely confirmed by the eyes through a mirror or the like, the top ends 12 of the brushing hairs can be fully reached to all parts of the teeth. At the same time, since a place 3 where the toothbrush is placed is shuttled, brushing with the toothbrush 7 is done without moving the hand and plaque is removed. Furthermore, a shuttle motion, e.g. the amplitude of vibration in its axial direction is about 4mm and the number thereof is about 2300 per minute, is suitable for the vibration of the toothbrush 7.
