Abstract: A method of transmitting a destination along with the user's current location to a central viewing site allowing the user set or change their travel plan while they are on their trip and minimize bandwidth use on expensive or slow networks. A byproduct of this method is the transmission device can record the detailed path traveled by the user while transmitting enough user locations to give the viewer at the central viewing site a good indication of where the user has been. The detailed route traveled by the user is uploaded to the central viewing site when the transmission device is connected to a faster or less expensive network.

Abstract: A method for “team tracking” delivers position updates for multiple team members using a telecommunications network. Each team member/user carries a handheld and field-portable tracking and messaging device (TMD) that is used to send the current position of the device user to a networked server. The TMD has a built-in GPS receiver which provides the current position coordinates of the user. This position data is periodically transmitted via the telecommunications network to a central server. Team Status Messages (TSM) are sent regularly to each team member, the TSM containing the last known position of each team member. The position data are displayed over a map background, so that each member can see the positions of the other members. When tracking a target, a route is mapped to the target. If the target changes location, the next TSM that is sent indicates a re-calculated map to the target.

Abstract: A method of generating a pick packet for use by a web browser. The pick packet has secondary string buffer that assigns a unique token to each unique object or unique combination of objects and a primary string buffer that associates a token with each pixel in the source image. A description or legend is associated with the tokens in the secondary string buffer. When a pointer device hovers over a pixel in the source image, the browser looks in the primary buffer for the toke associated with that pixel, then retrieves the legend associated with that token, if any, from the secondary buffer.
