Tide display device
View Patent ↗A tide display device comprises a storage mechanism that stores tide information by surf spot. The device has a microprocessor that is programmed to display the tide height both graphically and numerically.
1. A tide display watch, comprising:
a storage device that stores tide information including a tide height and an associated time of day for each of a plurality of surf spots; and
a display screen that simultaneously displays a current time, a graph displaying tide heights on a vertical axis and time increments on a horizontal axis with a numeric labeling of the time increments on the horizontal axis, the graph including the tide height at the current time for a selected geographic location, and an exact numeric value of the tide height separate from the tide heights on the vertical axis of the graph, the numeric value being continuously updated to represent the tide height at the current time for the selected geographic location.
2. The watch of claim 1 , wherein the exact numeric value of the tide height can be displayed in feet, meters, or as a coefficient.
3. The watch of claim 1 , further comprising a third tide height indication displayed on the display screen.
4. The watch of claim 3 , wherein the third tide height indication is a moon phase.
5. The watch of claim 1 , wherein the tide information includes up to two high tide values and two low tide values for each of the plurality of surf spots.
6. The watch of claim 1 , wherein the tide information further includes a continent.
7. The watch of claim 6 , wherein the tide information further includes a country.
8. The watch of claim 1 , wherein the tide information is calculated by an oceanographer for exclusive use in the tide display device before being loaded into the storage device.
9. The watch of claim 1 , wherein the tide information is downloaded from a web server.
10. The watch of claim 9 , further comprising a 1394 port for downloading the tide information.
11. The watch of claim 9 , configured to use wireless technology for downloading the tide information.
12. The watch of claim 1 , wherein the graph is displayed as a series of pixels with the peaks representing high tides and the valleys representing low tides.
13. The watch of claim 1 , wherein the graph comprises approximately 6 hours of past tide heights and approximately 18 hours of future tide heights.
14. The watch of claim 13 , wherein the graph updates every 30 minutes.
15. The watch of claim 1 , further comprising a microprocessor programmed to alternately display tide heights for up to four beaches.
16. The watch of claim 1 , further comprising a microprocessor programmed to accept an adjustment for a custom beach and to display a tide height for the custom beach.
17. The watch of claim 1 , further comprising a heat timer that provides a heat time that is displayed on the display screen.
18. The watch of claim 1 , further comprising a wave counter that provides a wave count that is displayed on the display screen.
19. The watch of claim 1 , wherein the storage device is a removable flash memory card.
20. The watch of claim 1 , further comprising a wrist band that is coupled to the display screen.
21. The watch of claim 1 , further comprising an attachment mechanism comprising Velcro™ that is coupled to the display screen.
22. A tide display watch, comprising:
a tide height graph that displays tide heights on a vertical axis and time increments on a horizontal axis, and displays a specific numeric value indicating a tide height at a current time distinct from any numerical values representing the tide heights on the vertical axis.
23. A watch, comprising:
a housing having a display screen;
a band attached to the housing;
a memory module in the housing for storing a plurality of tide heights over a period of time for a geographic location; and
a microprocessor in the housing for simultaneously displaying on the display screen a graph showing the plurality of tide heights over the period of time for the geographic location, a current time line on the graph representing a current time, and a numeric tide height value separate from the graph, the numeric tide height value being continuously updated to represent a height of a tide at the current time at the geographic location.
24. The watch of claim 23 , wherein the microprocessor simultaneously displays on the display screen the graph and the numeric tide height value representing one of the plurality of tide heights shown on the graph.
25. The watch of claim 23 , wherein the graph comprises approximately 6 hours of past tide heights and approximately 18 hours of future tide heights.
26. The watch of claim 23 , wherein the microprocessor is programmed to accept an adjustment for a custom beach and to display on the display screen tide heights for the custom beach.
