Abstract
A locator device includes a pocket-sized casing that contains a keyless remote entry circuit for remotely operating a vehicle security system. A GPS receiver circuit is located in the casing and automatically identifies a vehicle waypoint whenever the vehicle is turned off. The locator device then determines from any current location and with a single button press the direction and/or distance back to the vehicle waypoint. Many other novel applications are also performed by the locator device.
Claims20
A wireless telephone comprising:
- a locator circuit configured to receive a first waypoint after a first triggering event and configured to determine directional information from a current location to the first waypoint, wherein the first waypoint is calculated prior to the first triggering event;
- and
- a display for showing the directional information.
A locator device, comprising:
- a pocket-sized casing;
- a GPS receiver circuit located inside the casing and configured to identify a first location of the locator device;
- a memory configured to store a second location of the locator device;
- a processor configured to derive a direction and distance from the first location to the second location:
- and
- a transceiver located inside the casing and configured to wirelessly transmit the first location and an identifier to another device after a triggering event occurs.
A method comprising:
- storing a first GPS waypoint in a handheld locator device;
- identifying when a triggering event occurs;
- transmitting the first GPS waypoint to another device after the triggering event;
- storing a second GPS waypoint in the handheld locator device;
- and
- identifying a target direction from the second GPS waypoint to the first GPS waypoint.
