Autonomous Black Hawk Helicopter

Sikorsky Aircraft Corporation
Stratford, CT

Sikorsky Aircraft, a subsidiary of United Technologies Corp., is developing its first product to feature Matrix™ Technology by converting a retired UH-60A Black Hawk helicopter into an optionally piloted variant capable of a wide spectrum of missions. With the autonomous Black Hawk, Sikorsky plans to build on the success of its Matrix Technology and Manned/Unmanned Resupply Aerial Lifter (MURAL) autonomy programs to deliver a new level of mission flexibility to combat and logistic planners. The product will integrate autonomy and advanced fleet management technology with refurbishment experience to provide a cost-effective, dependable and sustainable system.

Developing and Validating Statistical Cyber Defenses

Enterprise business processes are more connected than ever before, driven by the ability to share the right information with the right partners at the right time. While this interconnectedness and situational awareness is crucial to success, it also opens the possibility for misuse of the same capabilities by sophisticated adversaries to spread attacks and corrupt critical, sensitive information. This is particularly true for an insider threat scenario in which adversaries have legitimate access to some resources and unauthorized access to other resources that is not directly controlled by a fine-grained policy.

Next-Generation Spectrometers for Rapid Analysis of Complex Mixtures

Molecules have internal motions that are characteristic of their structure and identity. These motions can be studied by spectroscopy in different regions of the electromagnetic spectrum. Molecular spectra can be used as a “fingerprint” to unambiguously state whether or not a particular chemical is present and in what amount. As such, small portable spectrometers are frequently used as components of chemical sensors.

Wireless Vital Signs Monitor for Trauma Patients

A miniature, portable wireless vital signs monitor (MWVSM), called Mini-medic™, could aid in the triage and diagnosis of trauma patients with and without traumatic brain injury (TBI). The MWVSM consists of two components, both of which are the approximate size and weight of a cellphone: one is a sensor that is placed either on the forehead or the fingertip of a patient, and the other is a monitor that receives a wireless signal transmitted up to 100 m carried by the medic.

Analysis of an In-Ear Dosimeter for a Single Hearing Protection Device

US national and many international hearing conservation programs (HCPs) have adopted a noise exposure criterion of 85 dBA for a time-weighted average of 8 hours, with a 3 dB per doubling exchange rate (safe exposure duration was cut in half for each 3 dB increase in noise level). Military personnel who work in extreme noise environments require high attenuation from hearing protection in order to complete a normal duty day without risk of permanent hearing loss. Improvements to both hearing protection and noise dose monitoring have been consistently recommended and pursued as a means to reduce risk for noise-induced hearing loss.

Tata Technologies Researchers Use CFD to Predict Cavitation in Liquid Ring Pumps

Liquid ring pumps are used in aircraft fuel systems in conjunction with main impeller pumps. These pumps are used for priming the pump system as well as to remove fuel vapor and air from the fuel. Prediction of cavitation in liquid ring pumps is important as cavitation degrades the performance of these pumps and leads to their failure. As test-based assessment of cavitation risk in liquid ring pumps is expensive and time consuming, recent approaches have been to assess and predict the risk of cavitation using CFD methods with the goal to quicken the design process and optimize the performance of these pumps.

Safety Laser Scanners

Omron Automation and Safety's (Schaumburg, IL) new OS32C-4M Type 3 safety laser scanners provide a 4 meter safety range, 15 meter warning zones and a 270 degree detection angle for safeguarding large robotic cells and body entry detection. They can also be mounted 4 meters high to eliminate the possibility of tampering. New pollution tolerance modes ensure safe machine operation, even in the dirtiest and dustiest application environments. All OS32C safety laser scanners provide configurable object resolutions of 30, 40, 50 and 70 mm to accommodate hand and arm detection applications. They feature a compact 104.5 mm profile, light 1.3 kg weight and consume just 5 W power (3.75 W in standby mode).
