Latest Patents

One of Johnston's latest patents is an "Apparatus and amendment of wind turbine blade impact detection and analysis." This multisensory system is designed to provide both temporal and spatial coverage capacities for the auto-detection of bird collision events. The system includes an apparatus with circuitry to capture and store a series of images or video of a wind turbine blade. It also features sensors that continuously sense vibration or record acoustic data. The second circuitry analyzes the sensor data and images to identify the cause of vibrations and trigger the cameras. Additionally, a communication interface transmits data to other devices, utilizing artificial intelligence or machine learning to control sensor sensitivity.

Another notable patent is the "Integrated circuit for low-voltage thermoelectric energy harvesting with self-start." This integrated circuit lowers the start-up voltage to approximately 50 mV, making it compatible for starting a DC-DC converter from a thermoelectric generator (TEG) even with a small temperature gradient. The IC enhances the end-to-end efficiency of the energy harvester by improving the power efficiency of the DC-DC converter while ensuring maximum power transfer from the TEG at low voltages. It employs a low voltage integrated charge pump to boost sub-100 mV input voltage and generates a startup clock with a ring-oscillator that operates at low supply levels.
