Filed:

May 26, 2005

Appl. No.:

11/138933

Inventors:

Jeffrey H. Gertsch - Palo Alto CA, US
Ronald L. Gertsch - San Diego CA, US
Christopher L. Gehrisch - Vista CA, US
Matthew B. Gehrisch - Vista CA, US
Martin D. McCune - San Diego CA, US

International Classification:

A42B 1/24

US Classification:

2422, 2410

Abstract:

An electronic helmet is provided that includes a helmet body and an integrated electronic system disposed in the helmet body, providing a number of convenient functions. The helmet body has a hard outer shell and a hard inner shell mounted to the outer shell such that a cavity is defined between the outer and the inner shells. The inner shell can include suitable material to provide the wearer effective RF shielding from the electronic system, such as, nickel-plated carbon fiber to provide RF shielding. The helmet body further includes a shock-absorbent structure disposed between the inner shell and the head of a wearer.

Abstract:

A strong, lightweight composite material having beneficial flexing characteristics is made using a unique reinforcement material. The reinforcement material comprises a fabric incorporating glass rovings with graphite tows in an architectural combination that retains the properties of both materials. Composite structures made using this reinforcement material with a thermosetting or thermoplastic matrix are extremely lightweight, with desirable anisotropic flexing properties. The finished composite structure is extremely useful as an arch support in a shoe to absorb and distribute the forces generated by walking. In distributing forces on the foot such a support will provide the desired stiffness along the longitudinal axis while allowing increased flexibility along the transverse axis.
