DISTANCE CALCULATOR DEVICES AND METHODS FOR GOLF PRACTICE RANGES
Distance measuring devices and methods are included which may be used to measure and simultaneously display an accurate range of multiple targets such as the flags of a golf practice driving range.
1 . A distance calculator for simultaneously displaying distances to a plurality of golfing targets, comprising:
memory storage which is configured to store a plurality of stored target positions;
a global positioning system receiver which determines a position of the distance calculator by receiving global positioning system satellite signal data;
a controller which is in operative communication with the memory storage and global positioning system receiver and which calculates a distance from each of a plurality of targets to the distance calculator based on respective stored target positions of the plurality of targets that are stored in the memory storage;
a plurality of distance displays which are each in operative communication with the controller, which each display a display distance corresponding to a stored target position of a corresponding target and which each are visible to a user; and
an update interface which is user actuated, which is in operative communication with the controller and which prompts the controller to automatically initiate calculation of display distances between each of the stored target positions to the position of the distance calculator, and update the display distances on each of the respective distance displays based on the calculated display distances.
2 . The distance calculator of claim 1 wherein the update interface comprises a button disposed on a housing of the distance calculator.
3 . The distance calculator of claim 2 wherein the button disposed on the housing comprises a recessed mechanical button which is positioned within the housing so as to permit actuation of the recessed mechanical button with a point of a golf tee.
4 . The distance calculator of claim 1 wherein the update interface comprises a remote control.
5 . The distance calculator of claim 4 wherein the update interface comprises a wireless link in wireless communication with the remote control.
6 . The distance calculator of claim 1 further comprising an auxiliary user interface operatively coupled to the controller.
7 . The distance calculator of claim 6 wherein the auxiliary user interface comprises a membrane switch disposed on the housing.
8 . The distance calculator of claim 1 wherein each of the distance displays comprise a screen that continues to display the display distance after power to the distance displays has been stopped.
9 . The distance calculator of claim 8 wherein each of the distance displays comprise a microencapsulated electrophoretic display.
10 . The distance calculator of claim 1 wherein the plurality of distance displays are disposed on a single display screen.
11 . The distance calculator of claim 1 wherein the plurality of distance displays are disposed on a plurality of display screens.
12 . The distance calculator of claim 11 wherein the plurality of distance displays are each disposed on a separate display screen.
13 . The distance calculator of claim 1 comprising 2 distance displays to 20 distance displays.
14 . The distance calculator of claim 1 further comprising a stored power source in operative communication with the controller.
15 . The distance calculator of claim 14 wherein the stored power source comprises a battery.
16 . The distance calculator of claim 1 wherein the memory storage comprises electrically erasable programmable read-only memory.
17 . The distance calculator of claim 1 further comprising a communication link that is operatively coupled to the controller and that is configured to transmit stored target position data to a communication link of another distance calculator that is configured to receive stored target position data.
18 . The distance calculator of claim 17 wherein the communication link comprises a wireless link.
19 . A distance calculator for simultaneously displaying distances to a plurality of golfing targets, comprising:
memory storage which is configured to store a plurality of stored target positions;
a location system which determines a position of the distance calculator by receiving location system data;
a controller which is in operative communication with the memory storage and location system and which calculates a distance from each of a plurality of targets to the distance calculator based on respective stored target positions of the plurality of targets that are stored in the memory storage;
a plurality of distance displays which are each in operative communication with the controller, which each display a display distance corresponding to a stored target position of a corresponding target and which each are visible to a user; and
an update interface which is user actuated, which is in operative communication with the controller and which prompts the controller to automatically initiate calculation of display distances between each of the stored target positions to the position of the distance calculator, and update the display distances on each of the respective distance displays based on the calculated display distances.
20 . A method of calculating distances on a golf course, comprising:
positioning a first distance calculator at a target on a golf course;
initiating global positioning system calculation of a target position with a global positioning system receiver of the first distance calculator and determining the target position while the first distance calculator is positioned at the target;
storing the target position into a memory storage of the first distance calculator; and
transmitting the target position through a communication link of the first distance calculator to a communication link of a second distance calculator.
21 . The method of claim 20 wherein the communication links comprise wireless communication links and the target position is transmitted wirelessly.
22 . The method of claim 20 further comprising calculating a display distance value measured between the target position and the hitting position with the first distance calculator.
23 . The method of claim 22 further comprising displaying the distance display value on a display of the first distance calculator.
