Multi-function apparatus and related method integrated with positioning/orientation mechanism
First Claim
1. A multi-function electronic apparatus with positioning/orientation mechanism capable of operating in a forward mode and a backward mode, wherein the forward mode indicates from a departure point to an end point, and the backward mode indicates from the end point to the departure point, the electronic apparatus comprising:
- a position module for detecting a current coordinate and a plurality of coordinates along a track which the electronic apparatus traveled;
a memory for recording the plurality of coordinates detected by the position module into a plurality of reference coordinates when the electronic apparatus is operating in a forward mode;
an orientation module for comparing the current coordinate and the reference coordinate of the memory when the electronic apparatus is operating in a backward mode;
a terrain module for providing a terrain data to record a number of undulant terrain counts along the track which the electronic apparatus traveled, if the electronic apparatus passes an undulant terrain, the terrain module increases the terrain data in the forward mode; and
if the electronic apparatus passes the undulant terrain, the terrain module decreases the terrain data in the backward mode; and
an orientation interface for providing a directional signal being utilized to indicate direction according the difference of the current coordinate and the reference coordinate.

Abstract
Multi-function apparatus and related method integrated with positioning/orientation mechanism. The apparatus of the invention works under a forward mode for recording reference coordinates/altitudes of a departure point and passing points along a track which a user moves. When the user wants to trace back, the apparatus works under a backward mode for comparing each of the recorded reference coordinates/altitudes with a current coordinate/altitude of the user, and providing direction/altitude orientation for the user so that the user can trace back to the original departure and/or passing points.

11. A method of indicating direction, comprising:
-
detecting a coordinate of a departure point and a plurality of coordinates along a track traveled; recording the coordinate of the departure point and the coordinates along a track traveled in a forward mode; comparing the current coordinate with the reference coordinates; providing terrain data to record a number of undulant terrain count along the track so that in the forward mode the terrain data increases progressively when an undulant terrain is passed; and
in a backward mode the terrain data decreases progressively when the undulant terrain is passed; andtransmitting a prompt for providing a direction of the reference coordinates according to a difference of the current coordinate and the reference coordinate of a departure point. - View Dependent Claims (12, 13, 14, 15, 16)
