Control algorithm for helmet with wireless sensor
First Claim
Patent Images
1. A helmet comprising:
- at least one pad that is stiffenable and destiffenable;
a wireless sensor system comprising;
a pool of distributed antennas for transmission and reception;
a pool of transmitters and receivers to transmit a signal and receive reflected signals;
a computing device with memory to execute a control algorithm;
the control algorithm comprising;
an executable main program with a random wait or idle time that executes the control algorithm using a number of functions or subroutines to identify objects in surrounding environment of the helmet, and uses received reflected signals from surrounding objects to retrieve the information data for validation and calculation/estimation of direction, distance and the speed of any surrounding objects approaching the helmet to determine if any pad of the at least one pad, internal or external to the helmet, needs to be activated.

Abstract
A control algorithm for helmet with wireless sensor system for monitoring of surrounding objects. The control algorithm comprises of an outer antenna loop to use one of the antennas for transmission, an inner transmission and reception loop to transmit from one antenna and receive from one or more antennas to measure speed, distance and direction of an approaching object to determine when and where an impact will occur, and a number of stiffenable and destiffenable pads installed on the helmet and external to the helmet that will be activated prior to an impact.
