During Phase II period, Hstar plan to prototype an advanced mobile robotic nurse assistant (RoNA) system for augmenting nurses’ health care capabilities in a hospital environment with physical assistance. This RoNA system will: a) navigate intelligently in hospital environments with a mobile holonomic drive, b) support an intuitive interface guided by human-robot interaction and work safely and ...

The NOSTRA system monitors battery health by comparing observed voltage, current, and temperature data to models of both known healthy and known unhealthy battery packs. In Phase I of the NOSTRA program, we demonstrated that this model-based approach can generate accurate estimates of battery age. During Phase II, we will use this approach to estimate battery capacity and internal impedance, the ...

For the Stingray Project, iRobot Corporation and Chatten Associates will develop techniques for teleoperation of small, high-speed UGVs. Currently deployed small UGVs are limited in the missions that they can perform, due to their slow speed and the limited situational awareness that they provide to their operators. We will address these limitations by combining semi-autonomous driver-assist beh ...

The asymmetric warfare common today requires engagement of small groups and even solitary combatants. Currently, each unmanned system used for surveillance requires a single operator, and, collaboration between operators must be moderated in a complicated fashion. This configuration is not an effective usage of manpower and hinders the efficiency necessary for time-critical geolocation of elusi ...

Continuous environmental health monitoring is a growing requirement for missile systems to ensure their long-term reliability while being stored, transported and operated in harsh environmental conditions. While several sensors currently exist for measuring temperature, relative humidity, shock/vibration, and other key parameters, the wiring required for such a network of embedded sensors, special ...

Advances in interoperability promise to take patient safety to a new level via the application of process control engineering. While the path to a fully engineered process is difficult, benefits accrue each step toward it. This project will advance us along this path by demonstrating a prototype "Context-Aware Notification System." By bringing together comprehensively 1) physiologic data, 2) pat ...

The proposed Mayflower Low Elevation Antenna Nuller (M-LEAN) unit consists of a circular array and a miniaturized Digital Antenna Electronics (DAE) module. The DAE module will be implemented with the Mayflower Anti-Jam (AJ) ASIC chip set (“Beacon” RF ASIC and “Vanguard” Digital AJ ASIC) in an integrated assembly compatible with the Army program objectives of small size (less than 27 cubic ...

Current pitch rods are used to adjust the pitch on the main rotor blades. The collective pitch control is actuated through the swashplate to change the pitch of each blade all at once. There is no current method to individually change the pitch of only one blade individually in production, but there have been some research activities in this area. The technology proposed would remove the curren ...

Helicopter blade systems are constructed to tight tolerances, but slight manufacturing variations cause lift to vary from blade to blade at certain specific flight conditions. The resulting unbalanced lift forces cause undesirable 1/rev vibration. The current practice calls for adjustments to be made by ground crew maintenance personnel; pitch control rod, aluminum trim tabs, and rotor head mass ...

We propose a hybrid system framework for detecting, classifying, and mitigating Malicious Outbound Network Traffic flows based on our work in botnet detection, security risk management, covert channel detection and intrusion detection. In particular, we propose to develop a taxonomy of data exfiltration based on application classes and underlying protocols, select a representative set of data exfi ...
