  • Wearable Low Power Continuous Perinatal Monitor
    Publication number: 20220265159
    Abstract: A sensing device for sensing perinatal maternal uterine activity and fetal heart activity is provided. The sensing device includes a body with an electromechanical system and a housing, a passive acoustic system with a plurality of microphones and an acoustic waveguide, an attachment component, an accelerometer, a signal analysis system including a microcontroller unit, and a wireless transceiver. The signal analysis system is configured to process biopotential signals and acoustic signals detected by the passive acoustic system and to reduce motion artifacts from the signals using the accelerometer.

  • System And Method To Create A Traveling Wave Within A Photobiotic Reactor To Enhance Algae Growth
    Publication number: 20110281339
    Abstract: A photobioreactor with a gas input is disclosed herein. The photobioreactor is tilted about an axis of rotation at various angles to provide for various flow patterns of bubbles created by the gas input. The flow patterns may vary, but include: bubble flow; slug or plug flow; churn; annular flow; or wispy annular flow. In certain configurations, a bubble flowing through the photobioreactor may increase algae growth within the reactor.
