Linear Motors

Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

Self-Diagnostic Accelerometer Field Programmable Gate Array

The system could be utilized as a portable and temporarily installed diagnostic system. John H. Glenn Research Center, Cleveland, Ohio The development of the self-diagnostic accelerometer (SDA) is important to both reducing the in-flight shutdowns (IFSD) rate — and hence reducing the rate at which this component failure type can put an aircraft in jeopardy — and also as a critical enabling technology for future automated malfunction diagnostic systems. Critical sensors, such as engine sensors, are inaccessible to the operator during typical operation due to safety concerns and enclosed environment. The SDA can diagnose the sensor in-flight and remotely with minimal interference with the typical operation of the sensor. The SDA system utilizes programmed health algorithms that can automatically determine the health, therefore increasing the precision in diagnosing sensor faults by removing the erroneous perspective and opinions of a human operator. The health of the sensor could also be determined immediately, which would remove its erroneous effect on a system that depends on the sensor.

Capacitively Coupled, High-Voltage Current Sensing for Extreme Environments

NASA’s Jet Propulsion Laboratory, Pasadena, California Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.

E-Textile Interconnect

Devices constructed from e-textiles have applications in law enforcement, by first-responders, and in wireless communications and computing. Lyndon B. Johnson Space Center, Houston, Texas E-textiles have shown great promise within the microwave and antenna community to provide a low-mass, highly conformal option that integrates extremely well with fabric-based microwave devices and antenna platforms, but often not as well with more conventional devices.

3D Volumetric Display Technology

The United States government spends a lot of money on its defense programs, investing in the training and technology necessary to arm and prepare the most advanced fighting force on the planet. The price tag for these efforts reached $581 billion in 20141 as various branches of defense continued to dedicate funds toward the research and development of innovative tools and technology.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.
