    摘要： A navigation system which can enhance the position determining accuracy of a mobile object without employing any high precision measuring instrument. The navigation system comprises a GPS range measuring device, an angular velocity measuring device, a velocity measuring device and an azimuth measuring device, which measure the motion of the mobile object; a GPS range error estimating device, an angular velocity error estimating device, a velocity error estimating device and an azimuth error estimating device, which estimate errors involved in the respectively corresponding measuring devices; and a position calculating device which calculates the position of the mobile object from the outputs of the error estimating devices. The error estimating devices are implemented by Kalman filters and averaging processes. The factors of the errors of the individual measuring devices are assumed, and the outputs thereof are corrected, so that the position of the mobile object can always be determined at a high accuracy without employing any high precision sensor.

    摘要： A system measures a traveling direction of a vehicle based on a direction toward a coordinate position defined by output data from a geomagnetic direction sensor from a first center coordinate position of a corresponding output circle. The system derives a second center coordinate position based on the output data from the geomagnetic direction sensor. The system utilizes a first group of the second center coordinate positions and a second group of the second center coordinate positions. When it is decided that the first center coordinate position is shifted, then a new or corrected center coordinate position is derived based on the first group of the second center coordinate positions, on the other hand, when it is decided that no shift of the first center coordinate position is generated, then the corrected center coordinate positiion is derived based on the second group of the second center coordinate positions.

    摘要： A heat-rest mounted at the upper edge of a seat back of a seat for a vehicle. The head-rest has stays in upright positions extending between upper and lower ends on upstanding brackets provided on both sides on the upper edge of the seat back frame, and a locking unit for locking the head-rest at desired height. Thus, the mounting strength of the head-rest can be reinforced while providing a good appearance without exposing the stays.
