Abstract

An enhanced protective helmet includes in one embodiment an outer shell and a molded lining disposed within the outer shell and contoured to surround a human head. The helmet further includes an elongated antenna having a proximal end and a free end, the antenna being supported by the molded lining. The helmet includes a connection point which can be mounted to the molded lining or otherwise extend away from the proximal end of the antenna, the connection point communicatively connected to the proximal end of the antenna. The connection point receives a connection from a mobile communication device, thereby linking the mobile communication device and the antenna. The antenna is located at helmet location that is along one side of the helmet above a left or right ear of the user for optimizing antenna performance.

a second antenna configured in an elongated form having a proximal end and a free end, the second antenna being supported by the molded lining and provided a dielectric load from the supporting substrate and achieving a prescribed electrical length using a respective physical length as a function of the dielectric load, whereby the connection point is communicatively connected to the proximal end of the second antenna,

wherein one of the first and second mobile communication devices is linked to the second antenna when the respective first mobile communication device or the second communication device is removably connected by a user to the connection point, and further wherein at least the second antenna is disposed in a helmet location that is along a side of the helmet above one of a left ear and a right ear of a user when the helmet is worn by the user.

2. The helmet of claim 1, wherein the molded lining comprises shock-absorbent material.

3. The helmet of claim 1, wherein at least one of the first and second antennas is supported across a surface of the molded lining.

4. The helmet of claim 1, wherein at least one of the first and second antennas is embedded within the molded lining.

5. The helmet of claim 1, wherein at least one of the first and second antennas is a frequency modulation (FM) antenna.

6. The helmet of claim 1, wherein at least one of the first and second antennas is a radio frequency (RF) antenna.

7. The helmet of claim 1, wherein at least one of the first and second connections points is a female-type connector.

8. The helmet of claim 1, wherein at least one of the connection points is interchangeable with an alternate connection point.

9. An enhanced protective helmet comprising:

a shaped foam element contoured to surround a human head, the shaped foam element comprising a shock-absorbent material and including a substrate for one or more antennas, and including a non-conductive surface that provides a dielectric support for the one or more antennas;

a first antenna configured in an elongated form having a proximal end and a free end, the first antenna being supported by the shaped foam element; and

provided a dielectric load from the supporting substrate and achieving a prescribed electrical length using a respective physical length as a function of the dielectric load; and

a connection point mounted along an external edge of the shaped foam element or mounted on an interior surface of the shaped foam element, the connection point communicatively connected to the proximal end of the first antenna and configured to removably connect to a first mobile communication device and further configured to removably connect to a second mobile communication device, thereby linking one of the first and second mobile communication devices to the first antenna when the respective first mobile communication device or the second communication device is removably connected by a user to the connection point;

wherein at least the first antenna is disposed in a helmet location that is along a side of the helmet generally above one of a left ear and a right ear of a user when the helmet is worn by the user;

a second antenna configured in an elongated form having a proximal end and a free end, the second-antenna being supported by the shaped foam element, and provided a dielectric load from the supporting substrate and achieving a prescribed electrical length using a respective physical length as a function of the dielectric load; and

wherein one of the first and second mobile communication devices is linked to the second antenna when the respective first mobile communication device or the second communication device is removably connected by a user to the connection point.

10. The helmet of claim 9, wherein at least a portion of the first antenna is embedded within the shaped foam element.
