Pedal Position Sensing in Heavy-Duty Vehicles

Pedal position detection is nothing new when it comes to operation of heavy duty equipment. However, the age old system operation of mechanical linkages between the pedal and the engine just might be coming to an end. New sensor technology is now enabling non-contact, drive-by-wire that can reduce total system cost while standing up to the harsh environments of off highway equipment.

Yoon, Korea University) A new, ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University. The film is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

How to Make Low Flow Measurements Using Turbine Flow Meters

Accurate low flow measurement represents significant challenges in many applications. Some typical low flow applications in the aerospace market include: small UAV fuel consumption, satellite thruster fuel consumption, and fuel/chemical/water injection. The low dynamic energy associated with flow rates down to 0.001 GPM exceed the capabilities of most mechanical flow meters and force the use of less accurate flow meter technologies.

SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

Temperature Sensors Cement the Integrity of Bridges

Thermal profilers, developed with NASA, ensure structural integrity of cement as it cures.The Obama administration wanted to foster partnerships with small- to medium-sized manufacturers through its Strong Cities, Strong Communities Initiative, wherein Federal agencies around the country are asked to mentor local businesses. One of the communities selected was the Cleveland-Youngstown region of Ohio, resulting in a call to Glenn Research Center. The Adopt a City program was launched, in which eight companies were identified to receive 40 hours each of assistance from experts at Glenn.

Auto Crash Sensor

Meggitt Sensing Systems (Irvine, CA) introduced the Endevco model 7264H optimally gas-damped accelerometer for automotive safety testing. The sensor is small in size and mass, and eliminates irrelevant frequency content generated by breaking glass and metal-to-metal impact. The MEMS accelerometer performs consistently over temperatures ranging from –18 to +66 °C (0 to 150 °F), and has a .50:.85 damping ratio and a 10,000g shock capacity. The frequency response is flat from DC to 3,500 Hz. It has a two-active-arm, full-bridge circuit with fixed completion resistors to facilitate shunt calibration. The full-scale output is 200 mV nominal with 10 Vdc excitation. The accelerometer comes standard with 2-, 5-, and 10-volt calibration data.
