Historical Invocon developed a low-power Conformal Ice Sensor for Boeing’s version of the Joint Strike Fighter (JSF). The flush-mounted sensor was developed to detect ice underneath the de-icing boots near the leading edge skins and engine air intake nacelles of the aircraft.  The sensor used multiple MEMS transducers along with software algorithms to determine the…

Historical The Extended-Life Micro-miniature Wireless Instrumentation System (ELMWIS) is a wireless data acquisition network for near-static sensing and recording applications. It was designed as a combination of the original MicroWIS™ and MicroRecorder™ systems which enables it to both store and communicate wirelessly. The ELMWIS Remote Unit (pictured)is a small, extremely low-power, autonomous, wireless device designed for extended data acquisition and recording.…

Historical Invocon concluded a Phase I Small Business Innovation Research (SBIR) contract with the Department of Transportation to develop an ESBAWM system. The purpose of ESBAWM is to monitor and log ballast exchanges in oceanic cargo vessels. These type of ships are required to perform a deep-ocean ballast exchange between ports to reduce the risk…

Historical In 1996 NASA awarded Invocon a contract to design and build a GPS controller that would act as an interface and data recorder between a GPS Trimble Advanced Navigation (TANS) Receiver unit and the Wake Shield Facility (WSF) Satellite data communications system. The controller was mounted on the cross-bay structure that supported the Wake…

Historical MicroSAFE is a miniature Smart Sensor that measures and processes strain data using the ASTM Rainflow Cycle Counting Algorithm. The result of this algorithm is a histogram showing the number of deflections at different stress levels. Over 1 year of processed data can be stored internally in non-volatile memory. The standard battery (not pictured) allows for…

Historical The MicroSGU is a small, battery-powered, wirelessly programmable, strain gauge data recorder. Each unit was designed to “sleep” in a low-power consumption mode until a certain time set by the user at which time the unit will then enter into a circular buffered data trigger mode sampling at 250 Hz using programmable trigger threshold…

Historical The MicroTAU system is a network of small, battery powered, wirelessly programmable, tri-axial acceleration data recorders. Each unit was designed to “sleep” in a low power consumption mode until a certain time set by the user where it will then enter into a circular buffered data trigger mode sampling at 250 Hz using programmable…

Historical MicroWIS-CO2 is a wireless data acquisition system for near-static sensing and recordingapplications. The system was developed for NASA to provide wireless carbon dioxide measurements inside NEEMO (NASA Extreme Environment Operations), an undersea astronaut training facility. It was also developed for possible use in the International Space Station (ISS) for monitoring carbon dioxide concentrations throughout the…

Historical The MicroRecorder is a data acquisition unit that measures and stores data that can be later downloaded to a PC. Over one month of data (at one sample per minute) can be recorded on internal non-volatile memory. Each unit has one external input channel from a resistive sensor and an internal temperature channel. The…

Historical This project concentrated on the miniaturization of wireless instrumentation system technology.  The development effort included the conceptual design, fabrication, and demonstration of a battery-powered, miniature wireless temperature sensor. The prototype device provided reliable data over the entire industrial temperature range (-40°C to -85°C) while consuming only tens of microamps in the active data acquisition…
