Feature-packed accelerometer claims to be world's smallest

The MEMSIC MXC6226XC digital accelerometer is the world’s smallest production accelerometer, measuring 1.2 mm x 1.7 mm x 1.0 mm. Its extremely small size and availability in a ball grid array (BGA) package provides designers enhanced flexibility for integration into space-constrained designs. The device integrates extensive signal conditioning circuitry, including a DSP, to enable superior motion sensing performance at a cost-sensitive price point for systems such as cell phones, toys, games, cameras, and appliances. It also serves as a high value-added replacement to designs employing mechanical switches, which are much less reliable and less capable.

Magnetic rotary sensors

R-Series magnetic rotary angle sensors use the orientation of a magnetic pick-up to determine angle so that there is no mechanical wear. An embedded microprocessor, contained within the R-Series sensors, converts the magnetic orientation to an analog output that is repeatable to within 0.03% or 0.1° of measurement range – depending on model. These rotary position sensors can be programmed and reprogrammed for your application’s angle and CW/CCW direction, and single or redundant output can be selected. R-Series have a measurement range up to 360° and have 12- or 14-bit resolution, depending on model.

Miniature extended-range proximity sensors

X-Series Pile Driver Extended Range Inductive Sensors are now available in 8-mm diameter models. With barrel lengths as short as 35 mm, these little sensors deliver a 3-mm sensing range – 50% more range than is available from larger, competitive 12-mm-diameter models. As a result, these sensors eliminate the need to sacrifice sensing range or durability. Like all Pile Driver sensors, its robust, single-piece machined barrel is fully embeddable in steel, making it an ideal sensing solution for the toughest metalforming and welding applications.

Oxygen and CO2 sensors

One of the largest costs of monitoring gas levels is the ongoing costs of sensor calibration. The CO2Meter.com line of oxygen and oxygen-carbon dioxide combination sensors drastically reduces maintenance costs by simplifying the calibration process. The TR250Z Oxygen Sensor is designed to be calibrated in-situ with the push of a button using normal room air. This simplified process means that calibration can now be done quickly and at regular intervals by available maintenance personnel instead of outsourcing the task. In addition, this sensor can be monitored off-site, or manually calibrated for ISO, FDA, or other compliance certification.

Steel mill LVDT position sensor

This non-contacting LVDT position sensor keeps steel-rolling mill operations running smoothly with less downtime. The Steel Mill Position Sensor monitors the position of milling frames that support rollers during the hot-rolling process. Position feedback ensures frames don’t deform or shift during the rolling process. These highly rugged LVDTs can also be used to monitor the position of the rollers themselves.

Hydrogen pressure sensor for fuel-cell vehicles

The AST 2000H2 Hydrogen ASIC Pressure Sensor was developed for use on hydrogen-powered vehicles and in other emerging hydrogen applications. The AST 2000 Hydrogen Pressure Sensors are already certified for use by European and Asian automobile manufacturers as on-board hydrogen sensors for fuel-cell vehicles. Anticipated volume production for these vehicles will begin 2014/2015. These sensors employ a one-piece thick diaphragm, free of internal o-rings, welds, or fill fluids, that keeps hazardous media out, eliminating the chance of hydrogen permeation and eventual sensor failure. To reduce the chance of embrittlement caused by long-term exposure to hydrogen, units are constructed from a version of high-strength 316L stainless steel wetted parts that promotes long life and resistance to media corrosion.

SMD current-sensing resistors

Stackpole Electronics has added the 1210 size to the CSR/CSRN series of thick-film SMD current-sensing chip resistors. The CSR1210 has a 0.5-W power rating and can achieve resistance values from 0.01 ohms up to 1 ohm in tolerances as low as 1%. For current sensing, the 1210-size chip offers distinct advantages in that the wider termination enables the part to handle more current than the 1206 size at temperatures tyically10°C to 15°C lower. This resistor is ideal for applications where resistance values are above 10 milliohms and TCR requirements are 200 ppm and higher, including power management for a wide range of power supplies, small motor controls, DC to DC converters, battery management, instrumentation amplifiers, voltage regulation modules, and industrial controls.

RoboCopters summoned by iPad apps are already in the works for U.S. Navy and Marines

By Grace Jean, Office of Naval Research

Marines running low on ammo may one day use an app on their digital handhelds to summon a robotic helicopter to deliver supplies within minutes, enabled by technologies from a new Office of Naval Research (ONR) program.

The Autonomous Aerial Cargo Utility System (AACUS) is a five-year, $98 million effort to develop sensors and control technologies for robotic vertical take-off and landing aircraft.

"AACUS is a leap-ahead technology that allows the Navy and the Marine Corps to move beyond having a highly trained operator fly an unmanned aircraft," says Rear Adm. Matthew Klunder, chief of naval research. "The program will let us leverage advanced autonomy, but still maintain the central and critical role of the human operator as the supervisor."

Marines based at outposts or in the field will be able to request the autonomous cargo helicopters for rapid resupply of combat essentials.

"We want to turn any helicopter into a logistics machine," says Dr. Mary "Missy" Cummings, program officer for AACUS, ONR's newest innovative naval prototype. "In the near term, we want to succeed in fully autonomous landings in austere locations, so Marines can get whatever they need on demand.

"In the long term, this could be a real life saver and revolutionize first response," she says. While rapid resupply is the immediate focus for AACUS, long-term applications could include critical medical missions such as casualty evacuation."

Program officials are seeking researchers who will develop threat- and obstacle-detection and avoidance systems, as well as autonomous landing capabilities that can operate across different types of aircraft. They expect teams from industry and academia to join forces to compete for the contracts.

Proposals are due Feb. 22. Officials plan to award up to two contracts in April.

The effort follows the Marine Corps Warfighting Laboratory's successful program to develop an unmanned system capable of hauling cargo semi-autonomously to landing zones at bases. The prototype, called K-MAX, flew its first combat mission in Afghanistan in mid-December, resupplying Marines with cargo carried in a sling-load.

AACUS, on the other hand, is aimed at internal load-carrying capacity. It will be a major leap ahead in autonomy, says Cummings. While K-MAX requires a trained operator within line-of-sight to fly, any operator will be able to call for AACUS from any location.

"It's going to be designed to work with people who have no flight experience," she says. "An operator will pick up his iPad or Android and make an emergency supply request. He'll request that the helicopter come to him and land as close to him as possible."

The helicopter not only will take off by itself, but will plan its own flight path and navigate its way through the airspace, requiring little to no input from an operator other than to verify its proposed landing site. The concept will require improvement in data processing.

"How you take the data from sensors and integrate them to make these decisions - that's one of the big leaps," says Cummings. "It's like putting a frontal lobe on the helicopter."
