We present and demonstrate an innovative and extremely low cost aerial monitoring and surveillance platform based on integrating open source and small unmanned aerial vehicles (UAV) with a highly capable compact, lightweight smart phone. We investigated sensors available within smart phones such as the camera, GPS, gyroscope and accelerometer, to integrate computing and sensing capabilities to the UAV in an extremely cost-effective way, which could fundamentally affect the way UAVs are used in emergency response and other applications.

Replacement of the diseased shoulder joint with implants is a procedure whose frequency is rapidly increasing. However, glenoid replacement remains challenging due to the difficult joint exposure and visualization of anatomical reference landmarks during the procedure. Improper positioning of the glenoid component can lead to early failure. The objective of this study was to develop and evaluate a Computer Assisted Glenoid Implantation (CAGI) technique to achieve a more accurate and reliable placement of the glenoid component. Twenty cadaveric scapulae were imaged with CT. The accuracy of an electromagnetic tracking system and 3D surface modeling for the measurement of glenoid position was compared to that of the standard CT-based method. Custom jigs were then developed to track instruments and to correct for scapular motion during in vitro trials. A standardized protocol for determining, in real time, the glenoid position and placement was developed and validated. The version angle...
