Capacitive Force Sensor

Pressure Profile Systems (Los Angeles, CA) has released the SingleTact, a miniature capacitive force sensor. The ultra-thin, single-element device quantifies forces in analog or digital configuration. The SingleTact interface board can be customized for an engineer’s specific application. A choice of six sensor configurations is provided, including 8-mm and 15-mm diameter sensors, and force ranges from 100 grams to 45 kg full scale.

Improved Ground Collision Avoidance System for General Aviation Aircraft and UAVs

This advanced warning system uses cutting-edge fighter jet technology to prevent controlled flight into terrain, which is a leading cause of aviation fatalities. Armstrong Flight Research Center, Edwards, California Controlled flight into terrain (CFIT) causes almost 100 deaths each year in the United States. Although warning systems have virtually eliminated CFIT for large commercial air carriers, the problem still remains for general aviation aircraft and unmanned aerial vehicles (UAVs). Existing systems are forced to rely on digital maps with low resolution/fidelity. They also require expensive equipment, limit the maneuvers to avoid collision, and frequently issue false alarms, causing pilots to ignore the safety system.

Programmable Linear Position Sensors Leverage Inductive Technology

Benefits include maximizing noise rejection, compensating for mounting position without moving the sensor, error detection, and eliminating the need for a programmable process monitor. Novotechnik, Southborough, Massachusetts New technology combines the benefits of non-contact linear position sensing with the programmability of a programmable controller in a relatively small sensor package. This technology can help engineers in applications including those where costs and/or development time can be saved with all necessary control functions handled by the position sensor, applications requiring high accuracy over a small distance, and applications with high vibration or noisy environments. Practical applications include material handling equipment, crimping machines, and position sensors for linear actuators.

Polarizing Sun Sensor

Commercial applications include agricultural, surveyor equipment, and energy conservation equipment installation. NASA’s Jet Propulsion Laboratory, Pasadena, California For a number of applications, the pointing direction towards the Sun must be known or measured. Con ventional Sun sensors determine the pointing direction towards the Sun while the Sun is in the field of view of the sensor. The disadvantage of a conventional Sun sensor is that it only operates when there is an unobstructed line of sight to the Sun. At some locations/seasons, it is virtually impossible to use a conventional Sun sensor.

Three-Axis Sun Sensor for Attitude Determination

This three-axis attitude determination sensor is based on Sun observations. NASA’s Jet Propulsion Laboratory, Pasadena, California A conventional Sun sensor determines the orientation of the Sun in two axes. If mounted on Earth in a known coordinate system, it can determine the azimuth and elevation of the Sun. When mounted on a spacecraft, it can determine the pointing direction toward the Sun. Traditionally, Sun sensors have been based on optical/detector configurations that would change the magnitude of an electrical signal based on the angular incidence of the Sun (analog Sun sensor). Other types of Sun sensors have relied on optics and a geometric pattern placed over the detectors that generated an on/off (digital) signal depending on the solar angle (digital Sun sensor).
