First Claim
Patent Images
1. A portable position acquisition apparatus, comprising:
- a battery for providing power to said position acquisition apparatus, said battery having a battery level characteristic;
a position detection unit that acquires position information pertaining to said position acquisition apparatus;
a memory that stores the position information; and
a controller operatively connected to said battery, said position detection unit and said memory, said controller receives the battery level characteristic of said battery, and dynamically determines how frequently position information is reacquired by said position detection unit based on at least the battery level characteristic of said battery, wherein said controller reduces how frequently position information is reacquired when the battery level characteristic indicates a reduced power level of said battery.
