1. A portable device comprising:
- a keypad being pressable by a user;
a microcontroller coupled to the keypad;
a Global Positioning System (GPS) sensor coupled to the microcontroller; and
a display coupled to the microcontroller;
wherein the microcontroller is operable to (a) direct the GPS sensor to request and receive first location coordinates of a first location of the user when the user presses the keypad, (b) store the first location coordinates, (c) direct the GPS sensor to request and receive second location coordinates at a second location when the user presses the keypad, (d) compare the first and second location coordinates and cause the display to indicate information directing the user from the second location to the first location.

Abstract
A location finder device uses a GPS (Global Positioning System) to lock in location coordinates of a user site or a stationary car and then uses GPS and the last locked-in coordinates to direct the user back to the original location. The device may use special encrypted, firm-coded language to handle each function and operation, such as to calculate all locked in coordinates and to display the distance for the user to return to the last locked-in location.

15. A system comprising:
-
a Global Positioning System (GPS);
a portable device comprising;
first and second buttons being pressable by a user;
a microcontroller coupled to the buttons;
a Global Positioning System (GPS) sensor coupled to the microcontroller, the GPS sensor being operable to transmit and receive signals with the Global Positioning System; and

18. A method performed by a portable locator device, the method comprising:
-
receiving a first input from a user at the portable locater device;
responsive to the first input, sending a signal to a Global Positioning System (GPS) to retrieve first location coordinates of the portable locater device from the GPS;
storing the first location coordinates in the portable locater device;
receiving a second input from a user at the portable locater device;
responsive to the second input, sending a signal to the GPS to retrieve second location coordinates of the portable device from the GPS;
comparing the second location coordinates to the first location coordinates; and
displaying a direction arrow to indicate a direction from the second location coordinates to the first location coordinates. - View Dependent Claims (19, 20, 21, 22, 23)
