Abstract

A helmet accessory mounting system includes a mounting device configured to couple to an outer surface of a side of a helmet. The mounting device includes a plurality of mounting locations configured to removeably couple to at least one accessory. A plurality of the plurality of mounting locations each includes an electrical node. A power supply is coupled to the mounting device. An electrical supply line electrically couples the power supply to each of the electrical nodes and the electrical supply line is contained at least partially within the mounting device.

First claim

What is claimed is:

1. A helmet accessory mounting system comprising:
a mounting device configured to couple to an outer surface of a side of a helmet, the mounting device including a plurality of mounting locations configured to releasably couple to at least one accessory, a plurality of the plurality of mounting locations each including an electrical node;
a power source mount coupled to the mounting device;
a power supply removeably coupled to the power source mount; and
an electrical supply line electrically coupling the power supply to each of the electrical nodes, the electrical supply line contained at least partially within the mounting device,
wherein the power source mount includes a hot shoe configured to electrically couple the power supply to the mounting device, the hot shoe including a plurality of contacts including a plurality of power supply contacts configured to transfer power from the power source to the at least one accessory and a plurality of data contacts configured to transfer data between a controller at the power source and a controller at the at least one accessory.

2. The helmet accessory mounting system of claim 1 , wherein the mounting device includes a recessed retaining groove configured to slidably, adjustably, and simultaneously receive a plurality of the at least one accessory thereon.

3. The helmet accessory mounting system of claim 2 , wherein a top surface of the mounting device between a top edge of the mounting device and the retaining groove includes at least one mounting location.

4. The helmet accessory mounting system of claim 3 , wherein the at least one mounting location on the top surface of the mounting device includes a Hall Effect sensor.

5. The helmet accessory mounting system of claim 3 , wherein the at least one mounting location on the top surface of the mounting device includes a threaded recess configured to receive a fastener from the at least one accessory.

6. The helmet accessory mounting system of claim 2 , wherein the recessed retaining groove is a first retaining groove, the mounting device including a second retaining groove configured to receive at least one of the at least one accessory, the second retaining groove being at an oblique angle relative to the first retaining groove.

7. The helmet accessory mounting system of claim 2 , wherein the recessed retaining groove is configured to receive the at least one accessory in at least a first location and a second location along a length of the retaining groove, the at least one accessory configured to be coupled to the electrical node to electrically connect the at least one accessory to the electrical supply line when the at least one accessory is in the first location and the accessory is configured to not be coupled to the electrical node and electrically disconnected from the electrical supply line when the accessory is in the second location.

8. The helmet accessory mounting system of claim 2 , wherein each electrical node includes a positive electrical contact, a negative electrical contact, a first data contact, and a second data contact each having a contact surface exposed through an outer surface of the mounting device and configured to couple to corresponding pins from the at least one accessory.

9. The helmet accessory mounting system of claim 8 , wherein the contact surfaces of the positive electrical contact, the negative electrical contact, the first data contact, and the second data contact are each flush with an outer surface of the mounting device.

10. The helmet accessory mounting system of claim 1 further comprising:
a power source mount coupled to the mounting device, the power source mount having a concaved inner surface configured to correspond to a curvature of a rear surface of the helmet, the power supply being removeably coupled to the power source mount.

11. The helmet accessory mounting system of claim 10 , wherein the power source mount is coupled to the mounting device by an adjustable fastener configured to move the mounting device relative to the power source mount to adjust the helmet accessory mounting system to a size of the helmet.

12. The helmet accessory mounting system of claim 1 , wherein the power supply comprises:
a first series-connected battery set including at least one battery cell connectable in series electrical communication;
a second series-connected battery set including at least one battery cell connectable in series electrical communication, the second series-connected battery set connected in parallel electrical communication with the first series-connected battery set; and
a first modular battery circuit in series electrical communication with the first series-connected battery set and a second modular battery circuit in series electrical communication with the second series-connected battery set, the first modular battery circuit and the second modular battery circuit being configured to prevent battery cell balancing.

13. The helmet accessory mounting system of claim 1 , wherein the mounting device is a first mounting device configured to couple to the outer surface of a first side of the helmet, the plurality of mounting locations being a first plurality of mounting locations, each electrical node being a first electrical node, the helmet accessory mounting system further comprising:
a second mounting device configured to couple to the outer surface of a second side of the helmet opposite the first side and including a second plurality of mounting locations configured to releasably couple to the at least one accessory, a plurality of the second plurality of mounting locations each including a second electrical node; and
a second electrical supply line electrically coupling the power supply to each of the second electrical nodes and contained at least partially within the second mounting device.

14. The helmet accessory mounting system of claim 13 further comprising:
a sensor configured to sense a condition associated with the at least one accessory being coupled to one of the first and second mounting devices.

15. The helmet accessory mounting system of claim 14 further comprising:
a switch in each of the first and second electrical supply lines, wherein each of the switches is closed when the sensor senses the condition associated with the accessory being coupled to one of the first and second mounting devices.

16. The helmet accessory mounting system of claim 13 further comprising:
an accessory presence sensor configured to sense a magnetic field associated with the at least one accessory.

17. A helmet system comprising:
a helmet having an outer surface, the outer surface having a first side and a second side opposed to the first side and a rear surface between the first side and second side;
a power source;
an accessory mounting assembly comprising:
a first mounting device coupled to the first side of the outer surface of the helmet and including a plurality of first mounting locations for removeably coupling to at least one accessory of a plurality of accessories, a plurality of the plurality of first mounting locations each including a first electrical node;
a second mounting device coupled to the second side of the outer surface of the helmet and including a plurality of second mounting locations for removeably coupling to at least one accessory of the plurality of accessories, a plurality of the plurality of second mounting locations each including a second electrical node; and
a power source mount coupled to the outer surface of the helmet, the power source mount having a concav
