A micro-electro-mechanical (MEMS) exhaust valve-based impact attenuating fluid filled cell for use in cushioning impact and decelerating of a wearer's body portion (e.g. head, shoulder, torso, etc.) after an impact. In combination with the use of accelerometers, pressure sensors, location and other electronics supply signals to a microcontroller, the controlled opening/closing of said exhaust valve (resulting in the expelling of said fluids with an optional combination with cell refill means) when certain parameters exceed a threshold. Individuals who engage in activities that carry a risk of injury to the head from impact in the normal course of the activity could, in combination with regular exams, benefit from a system that produces and updates a kinematic 3D model of the individual's head, including brain matter, cerebrospinal fluid paths, arterial and venous blood flow pathways, as well as the skull, supporting connective tissues and other biological structures in the head suitable for interaction with exogenous stimuli prepared from hypothetical or actual recorded impact events.

MEMS valve actuator system and method

MEMS valve actuator system

Embodiments may include a method, system and apparatus for providing a reference voltage supply. A series resistor is provided between a power supply and a bandgap circuit coupled to an amplifier. A shunt transistor circuit is operatively coupled to the series resistor. A programmable output voltage is provided based upon the shunt transistor circuit and a first value of the series resistor.
