Miniature Accelerometer

About one decade ago, the Ballistic Missile Defense Organization (BMDO), then the Strategic Defense Initiative Organization, funded Silicon Designs to develop radiation-hardened accelerometers for kinetic energy vehicles to measure the change in velocity resulting from rocket motor firings that occur while changing trajectory. Smaller than a person’s thumbnail, these devices have very low power requirements…

Heart Defibrillator Energy Source

Proper heart rhythms can often be reestablished by the sudden discharge of stored energy in this pulsed-power device which uses a capacitor originally developed for space-based lasers and accelerators. In the mid-1980’s, the Ballistic Missile Defense Organization (BMDO) funded a company now named Maxwell Technologies to develop a high energy-density thin-film capacitor – a device…

DeBakey Blood Pump

Based on turbine technology developed for use in liquid propellant rocket engines, this specially designed small, lightweight, high speed turbine pumps blood without damage to the delicate, individual blood cells. A joint effort beginning in 1988 between NASA and a group of doctors headed by Dr. Michael DeBakey led to development of this Ventricular Assist…

Active Pixel Sensor

Since the 1970’s when charged coupled devices (CCD’s) were first developed, camera and video companies have been seeking to improve the technology. CCD’s provide good image quality, but they are expensive, power hungry, and with the required accessory chips, bulky. Recognizing the shortcomings of CCD technology, and with the continuing need for lightweight imaging systems…
