1. A portable position acquisition apparatus, comprising:
- a position detection unit that acquires position information pertaining to said position acquisition apparatus, said position detection unit including at least a GPS receiver, and the position information acquired being based at least in part on information received by the GPS receiver;
a memory that stores the position information;
a battery for providing power to said position acquisition apparatus;
a controller operatively connected to said position detection unit, said memory and said battery, and said controller determines a position change amount based on the position information and previously-transmitted position information, compares the position change amount to a threshold amount, and determines when said position detection unit should reacquire the position information based on at least the position change amount; and
a communication interface that enables said position acquisition apparatus to transmit data to a remote device via a wireless channel,wherein the data being transmitted includes at least the position information,wherein said communication interface is controlled to transmit the position information to the remote device if the controller has determined that the position change amount exceeds the threshold amount,wherein at least one user setting is set from a remote location via a web interface, andwherein said controller causes said position detection unit to reacquire the position information dependent on the at least one user setting.

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.

4. A portable position acquisition apparatus, comprising:
-
a position detection unit that acquires position information pertaining to said position acquisition apparatus, said position detection unit including at least a GPS receiver, and the position information acquired being based at least in part on information received by the GPS receiver; a memory that stores the position information; a battery for providing power to said position acquisition apparatus; a communication interface that enables said position acquisition apparatus to transmit data to a remote device via a wireless channel, the data being transmitted includes at least the position information; and a controller operatively connected to said position detection unit, said memory, said communication interface and said battery, said controller causes said communication interface to transmit the data to the remote device, and said controller determines whether said portable position acquisition apparatus is in motion using the position information detected by said position detection unit, wherein if said portable position acquisition apparatus is determined to be in motion, then said communication interface transmits the data to the remote device on a periodic basis, and if said portable position acquisition apparatus is determined not to be in motion, then said communication interface does not transmit the data to the remote device on the periodic basis, wherein at least one user setting is capable of being set from a remote location via a web interface, the at least one user setting affects the frequency of the periodic basis by which said communication device transmits the data to the remote device. - View Dependent Claims (5, 6, 7, 8, 9, 11, 12)

10. A portable position acquisition apparatus, comprising:
-
a position detection unit that acquires position information pertaining to said position acquisition apparatus, said position detection unit including at least a GPS receiver, and the position information acquired being based at least in part on information received by the GPS receiver; a memory that stores the position information; a battery for providing power to said position acquisition apparatus; a communication interface that enables said position acquisition apparatus to transmit data to a remote device via a wireless channel, the data being transmitted includes at least the position information; and a controller operatively connected to said position detection unit, said memory, said communication interface and said battery, said controller causes said communication interface to transmit the data to the remote device, and said controller determines whether said portable position acquisition apparatus is in motion using the position information detected by said position detection unit, wherein at least one setting is configured to be set via a web interface, the at least one user setting causing reacquisition of position information by said position detection unit to occur more often or less often. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
