Latest Patents

One of her latest inventions is the Ceiling Fan Airflow Diffuser Apparatus. This apparatus enhances indoor cooling by creating elevated air speeds, improving room air circulation, and reducing energy consumption of cooling systems. The design features a diffuser support structure and a diffuser body positioned below the ceiling fan blades. The outer rim of the diffuser body has an annular opening, while a smaller concentric inner ring is joined to the outer rim with struts. This inner ring has a frustoconical shape and a central opening. Additionally, the apparatus may include directional visible light sources for flicker-free lighting or an integrated UV-C light source to inhibit airborne pathogens.

Another notable patent is the Ultrasonic Anemometers Systems for Sensing Air Flows in Rooms and Ducts. This system provides low-cost, low-power, and accurate wireless airflow sensors for measuring air velocities and temperatures in rooms and air delivery ducts. The anemometers utilize arrays of transmitter/receivers to measure multiple sound paths simultaneously, determining velocity vectors and volumetric flow paths. By measuring the differential times of flight (TOF) between transceivers, the system can accurately assess both the velocity and temperature of the air.
