Watch incorporating car key
View Patent ↗The present invention provides a wearable device comprising a mechanical watch movement located within a watch housing, and first and second straps connected to the watch housing, such that the device is suitable for wearing on a user's wrist. The first strap has a coin cell located in a cavity, and the second strap has a first electronic communication device located in a cavity. The coin cell and the electronic communication device are connected by a flexible circuit board. Advantageously, this may provide a wearable device having the functionality to interact with a remote security system of a vehicle, such as a keyless entry system or a keyless go system.
1. A wearable device suitable for wearing on a user's wrist, comprising:
a substantially metal watch housing containing a mechanical watch movement;
a first strap connected to said watch housing; and
a second strap connected to said watch housing;
wherein said first strap comprises a first cavity having a coin cell located therein; and
wherein said second strap comprises a second cavity having a first electronic communication device located therein;
wherein the coin cell and the first electronic communication device are connected by a flexible circuit board, wherein the flexible circuit board comprises one or more rigid portions, the rigid portions being connected by flexible portions,
and wherein the first electronic communication device comprises a transmitter arranged to communicate with a first remote security system of a vehicle,
further comprising a button set into one of the first strap and the second straps for activating said first electronic communication device;
wherein the one of the one or more rigid portions houses an input arranged to be pushed by a button plunger when a user presses the button.
2. The wearable device of claim 1 wherein at least one of the straps further comprises a second electronic communication device arranged to communicate with a second remote security system of the vehicle, the second electronic communication device being connected to said cell by the flexible circuit board.
3. The wearable device of claim 2 , wherein the second electronic communication device comprises a circuit for communicating with a keyless go system of the vehicle.
4. The wearable device of claim 3 wherein the second electronic communication device is operable to confirm that the wearable device is inside the vehicle.
5. The wearable device of claim 2 , wherein the first and second electronic communication devices comprise any of a near field communication device, a transponder, or a transceiver.
6. The wearable device of claim 2 , further comprising a button for activating the second electronic communication device.
7. The wearable device of claim 1 , wherein the first electronic communication device is arranged to communicate with a keyless entry system for unlocking the doors of the vehicle.
8. The wearable device of claim 1 , wherein the first strap and the second strap are at least partially formed of rubber.
9. The wearable device of claim 1 , wherein at least one of the first strap and the second strap comprises an indicator.
10. The wearable device of claim 9 , wherein the indicator comprises a light bulb, optionally wherein the light bulb comprises an LED.
11. The wearable device of claim 9 wherein the indicator indicates any of: functionality status remaining cell charge, or to indicate that the vehicle is within a predetermined range of the wearable device.
12. The wearable device of claim 1 , wherein the flexible circuit board is conformally coated.
13. The wearable device of claim 1 , wherein the cell is potted within a cell housing.
14. The wearable device of claim 1 , wherein the substantially metal watch housing is waterproof.
