Abstract
The invention herein pertains to sensing a ground surface with the foot while walking. Persons having foot and leg nerve damage are often unable to walk without assistance because they can not recognize the ground surface as with normal foot sensory perception. The electrical device herein includes a vibrator which is worn against the skin of the leg and signals the wearer immediately as the foot touches the ground surface. The preferred embodiment of the invention utilizes a shoe having a switch located proximate the heel with the vibrator positioned in a strap surrounding the wearer's knee.
Claims13
A device mounted on the leg for sensing the wearer's foot contact with a surface by the wearer, comprising:
- an electrical circuitry, a signal generator, a switch, a power supply, said power supply, switch and signal generator connected to said electrical circuitry, a strap, said strap for attachment proximate the wearer's knee, said strap attached to said signal generator whereby closing said switch by contacting the surface with the foot will activate said signal generator to send a signal to the wearer's knee.
An electrical sensing device for wearing on the leg proximate the knee to signal the wearer at the knee when the foot strikes the ground surface comprising:
- an electrical conductor, a battery, a push button switch and vibrator, said battery, push button switch, and vibrator connected to said electrical conductor to form a circuit, a shoe, said switch contained within said shoe, a leg strap, said vibrator positioned on said leg strap, said leg strap attached to the wearer's leg at least at knee height whereby the wearer placing the shoe on the ground closes the switch to activate said vibrator and signal the wearer.
