Abstract

Improved methods and systems for position acquisition and/or monitoring are disclosed. The position acquisition and/or monitoring can be performed with improved intelligence so that data acquisition, transmission and/or processing is reduced. As a result, the position acquisition and/or monitoring is able to be performed in a power efficient manner.

Claims

1. A portable position acquisition apparatus, comprising:

a position detection unit that detects position information pertaining to said position acquisition apparatus;

a memory that stores the position information;

a battery for providing power to said position acquisition apparatus; and

a controller operatively connected to said position detection unit, said memory and said battery, said controller determines motion of said portable position acquisition apparatus, and said controller determines whether said position detection unit should reacquire the position information based on at least (i) the determined motion of said portable position acquisition apparatus, and (ii) a battery level characteristic of said battery.
