  • Ultra sonic SCUBA diver tracking device hardware

    Creator:
    Lindsley, Christopher J.
    Abstract:
    Currently, there is no accurate, low-cost method to track divers. Watching bubbles can give you an approximate xy-location, and expensive underwater radios utilizing ultrasonic waves can work if the diver knows where they are. Traditional radio waves do not work well in water due to the conductive nature of water....

  • A nano-power wake-up circuit for RF energy harvesting wireless sensor networks

    Creator:
    Lindsley, Christopher J.
    Abstract:
    A fully integrated CMOS latched comparator is presented for use as a wake-up circuit that is attached to an RF energy harvester in a battery free wireless sensor network. The system consumes less than 36nA static current at 20°C and dissipates 2pJ of energy per conversion. The comparator comprises of...
