Sensing apparatus for a navigation system

Abstract

A sensing apparatus for use in a non-horizontally mounted vehicle navigation system includes a chip having a sensing element for detecting a direction based on an amount of a physical quantity applied thereto. The sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.

1 . A sensing apparatus for use in a non-horizontally mounted vehicle navigation system, the sensing apparatus comprising a chip including a sensing element for detecting a direction based on an amount of a physical quantity applied thereto, wherein the sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.  
   
   
       2 . The sensing apparatus according to  claim 1 , wherein sensing element is arranged to reduce an angle between a detection reference axis thereof and the direction of a physical quantity applied thereto that would otherwise result from the non-horizontal mounting of the vehicle navigation system.  
   
   
       3 . A chip for use in a sensing apparatus incorporated in a non-horizontally mounted vehicle navigation system, the chip including a sensing element for detecting a direction based on an amount of a physical quantity applied thereto, wherein the sensing element is arranged in the chip so as to at least partly compensate for the non-horizontal mounting of the vehicle navigation system in which the sensing apparatus is used.  
   
   
       4 . The chip according to  claim 3 , wherein sensing element is arranged to reduce an angle between as detection reference axis thereof and the direction of a physical quantity applied thereto that would otherwise result from the non-horizontal mounting of the vehicle navigation system.
