  • Micro-gravity Measurement Apparatus (MMA)

    Historical MMA is a system for the Japan Aerospace Exploration Agency (JAXA) to monitor micro-vibrations on the International Space Station, ISS. The Japanese ISS module will have multiple experiments performed in the micro-g environment. MMA will help correlate any experimental anomalies with ISS vibrations. These extraneous vibrations may be caused from spacecraft docking or from…

  • Programmable Surface Acoustic Wave Correlator (PSAW)

    Historical Invocon has teamed with NASA and Sandia National Labs to develop an ultra low power Direct Sequence Spread Spectrum (DSSS) radio based on a programmable Surface Acoustic Wave (PSAW) correlator. The PSAW will perform the primary function of the digital signal processor, down converter, demodulator, and baseband processor in a conventional (DSSS) receiver, but…

  • Sensor Control and Acquisition Telecommunications (SCAT)

    Historical NASA Johnson Space Center (JSC) sponsored Invocon’s development of “next generation” data acquisition and communications networking concepts to be deployed in, on, and around space structures under construction. The network required maximum efficiency to route low-speed digital data, high-speed digital data, and video data. All data transmission and reception at all three levels had…

  • Site Inspection of Gas Main by Helical Tomography (SIGHT)

    Historical Invocon co-developed a system to inspect the internal and external physical condition of subsurface pipe used for natural gas distribution. Designed to measure the wall thickness of the pipe, the system formulated a tomogram image of the cross-sectional area of the pipe. Whenever a leak is excavated for repair, the system would be able…

  • Wireless Data Acquisition System for Structural Monitoring and Evaluation (SMES)

    Historical The system was initially designed for the U.S. Department of Transportation as an experimentation tool to evaluate the performance of bridge structures under transient loads. This system acquired data from low and high level sensors to measure stress/strain, vibration, and temperature data at up to 60 points on the bridge structure. Each remote data…

  • Tension Measurement System (TMS™)

    Historical Invocon designed and developed a data acquisition system as an experimental tool to evaluate the performance of nylon dispersion bridles of a parafoil under transient loads, specifically to be used in parachute drop tests for the X38 vehicle preliminary flight tests. The X38 was under development to replace the three-seat Soyuz as a seven-person…

  • Ultrasonic Wireless Instrumentation System for Autonomous Leak Detection and Location (UltraWIS™)

    Historical NASA is seeking advanced habitation technologies that will facilitate planetary and space habitation by humans through the creation of “smart structures” capable of autonomous monitoring by embedded sensors. In order to increase reliability while reducing life-cycle costs and improving performance, Invocon is developing the UltraWIS system to assist in locating leaks within pressurized spacecraft…

  • Un-tethered Velocity of Sound Profiling Sensor (UVOSPS)

    Historical Invocon has recently finished a Phase II Small Business Innovation Research (SBIR) contract with the US Navy to develop the Un-tethered Velocity of Sounds Profiling Sensor (UVOSPS) system. The purpose of UVOSPS is to measure water column sound velocity in littoral regions. The sensor system includes multiple miniature probes that are periodically released to…

  • Video Micro Movement Sensor (VMMS)

    Historical The Video Micro Movement Sensor was developed to explore the possibilities of using miniature cameras as a tool for aircraft testing and inspection. The VMMS can take VGA sized pictures (640 x 480 pixels) for inspection purposes while providing 6 ultra-bright LEDs as a light source. In addition to taking still pictures, the camera…

  • Wireless Airborne Instrumentation System (WAIS™)

    Historical The WAIS system is a wireless instrumentation system designed for the Naval Air Warfare Center for aircraft testing. The Phase II hardware pictured above successfully flew aboard a CH-53 helicopter in 2001. The purpose of this system was to replace the wires between various test sensors and existing analog telemetry equipment.  The WAIS system…
