  • Co-Invented Bluetooth Indoor Proximity System(BLIPS), a cheap indoor tracking solution for First Responders that leverages Bluetooth and Wi-Fi signals to track cellular devices. Patent in progress.• Designed a PHP and JavaScript GUI for visualization of tracking data.• Developed mobile application software in Java for UAS. This provided UAS with the capability to search disaster zones for the presence of cellular devices and return a heat map of the area.Bluetooth Indoor Proximity Sensing (BLIPS):In its most basic form BLIPS is a binary proximity indicator. By sensing Bluetooth and WiFi signals from cellphones it is able to localize the presence of the cellphone to a small region or “zone”. This zone can then be broken down further into three sub zones; WiFi, Bluetooth, and combined RSSI. Proximity sensing is computationally easy and does not require advanced hardware. The system consists of a collection of beacons which are single board computers with the ability to communicate over Bluetooth and WiFi as a mesh network. Periodically each beacon will make a Bluetooth connection request. Nearby devices respond with their class and MAC addresses. Information about what devices were seen during a scan is sent back to the BLIPS server over WiFi. This identifying information can be checked against a database to determine who the device belongs to. For this use case the database would be populated with information pertaining to the responder’s cell phones. Unknown devices detected by the system are classified (e.g Cellphone, headset, printer, etc.). By combining multiple protocols we are able to improve the system resolution. The radius of detection for a WiFi signal is substantial (~100ft) whereas Bluetooth is a low energy protocol so the radius covered by this request is quite small (~20ft). This provides a good degree of localization on its own and is further improved by checking for overlap between beacon regions and in some cases examining RSSI. Voir moins

  Project Manager

   Explored advanced capabilities of Unmanned Aerial Systems(UAS) for disaster relief and first responders. Led a team of nine students and one professor in an effort to augment commercial off the shelf technologies. The goal was to provide a UAS with the capability to search a collapsed building and identify points of interest and possible survivors. Demonstrated capabilities of stereoscopic cameras, ultrasonic range finders, thermal imaging and target identification algorithms. Combined stereoscopic cameras with thermal imaging and LIDAR for simultaneous indoor navigation, collision avoidance, and warm body identification.
