Abstract: A field portable mass spectrometer system comprising a sample collector and a sample transporter. The sample transporter interfaces with the sample collector to receive sample deposits thereon. The system further comprises a time of flight (TOF) mass spectrometer. The time of flight mass spectrometer has a sealable opening that receives the sample transported via the sample transporter in an extraction region of the mass spectrometer. The system further comprises a control unit that processes a time series output by the mass spectrometer for a received sample and identifies one or more agents contained in the sample.

Abstract: An expandable sensor array including at least one expandable member movable between an unexpanded stowed state and an expanded deployed state and a plurality of sensors interconnected with the at least one inflatable member and operatively connected to form a sensor array.

Abstract: A general purpose surveillance system for remote surveillance applications. The system is comprised of one or more audio (e.g., microphone) or video (e.g., camera) surveillance devices that are wirelessly coupled with triggering devices. The system is capable of transmitting audio, video and still pictures via wireless transmission links. The wireless transmission links can be radio frequency (RF) links such as satellite up/down links and commercial cellular networks. Or, the wireless transmission links can be direct line of sight wireless communications such as infrared (IR). The system can be triggered to transmit audio and/or video data either remotely or internally. A variety of sensor types, including but not limited to, infrared sensors, motion sensors, acoustic sensors, magnetic sensors, or electric field sensors can act as a triggering mechanism.
