Abstract: A system and method for connecting a global positioning system (GPS) device with a digital image processing device and inputting position information into an image file captured by the digital image processing device. A system and method for inputting position information into a captured image employ a digital image processing device which generates an image file by capturing an image, and stores the image file, a GPS device which receives position information from a GPS satellite at regular time intervals; when the digital image processing device is connected with the GPS device, a GPS information storage unit which receives position information from the GPS device and stores the position information, and a GPS information input control unit which inputs position information excluding a timestamp, into an image file.

Abstract: A method and system for performing serial data communication between a main device and an external module connected to the main device. The data communication system and method include a main device, and an external module connected to the main device and communicating data with the main device. The external module transmits its identification information to the main device before the external module and the main device communicate the data between each other, and the main device receives the identification information from the external module, confirms its connection to the external module, and transmits an identification information confirmation signal to the external module.

Abstract: A battery container capable of stably accommodating AA type batteries, a CRV3 battery, and a customized battery manufactured for exclusively use with a particular device. The battery container includes a main body which accommodates two AA type batteries, one CRV3 battery, or one customized battery wider than the CRV3 battery and having a first wrong-insertion preventing element in a lateral extension portion, and a cover which is opened or closed to allow a battery to be inserted into or drawn out of the main body and which keeps the battery in the main body during use.

Abstract: Disclosed are a holder strap for a portable device, and a fixation guider for guiding the strap through an inserting hole of the portable device in order to fix the strap at the portable device without using an additional commercial tool. The strap can be used to hang the portable device on a hand, a neck, a bag, a purse, or the like. The fixation guider can be readily inserted into the inserting hole of the portable device. The fixation guider for the strap includes a strap holding portion for enclosing and holding the strap therein, and a projection portion extending from the strap holding portion and configured to insert in the inserting hole of the portable device.
