1. A system comprising a portable ocular reflex measuring device wherein the portable device comprises:

  • an eye orientation sensor wherein;

    the eye orientation sensor comprises a module selected from the group consisting of an image detector, a magnetic field detector, and an electrical potential detector; and

    the eye orientation sensor senses vertical movement and horizontal movement of at least one eye;

    a head orientation sensor wherein;

    the head orientation sensor is attachable to a person'"'"'s head;

    the head orientation sensor does not use an external pulsed magnetic field;

    the head orientation sensor senses pitch and yaw of the person'"'"'s head wherein pitch represents a rotation about a first axis representing up and down movement of the person'"'"'s face when the rear of the person'"'"'s head moves in the opposite direction and yaw represents horizontal movement of the face when looked at from the front about a second axis substantially aligned with the spine and perpendicular to the first axis; and

    the head orientation sensor senses pitch and yaw in a range of frequencies that comprises at least one frequency greater than 0.01 Hertz and less than 15 Hertz;

    the head orientation sensor comprises a micro-electro-mechanical system integrated circuit wherein the micro-electro-mechanical system comprises a module selected from the group consisting of an accelerometer, a magnetometer, and a gyroscope; and

    an electronic circuit wherein;

    the electronic circuit comprises a power supply, a communications unit, logic circuitry, a central processing unit, a memory unit; and

    sensor data pre-processing circuitry;

    the power supply comprises a battery;

    the electronic circuit is responsive to horizontal and vertical eye movement information received from the eye orientation sensor;

    the electronic circuit is responsive to pitch and yaw information received from the head orientation sensor;

    the electronic circuit uses a Fourier transform to generate a vertical gain signal and a vertical phase signal in response to the vertical eye movement information and the pitch information; and

    the electronic circuit uses a Fourier transform to generate a horizontal gain signal and a horizontal phase signal in response to the horizontal eye movement information and the yaw information.
