Latest Patents

Among his latest inventions, Krishna has patented a "Method for wall detection and localization." This innovative system is designed to perform wall detection and localization to ascertain the position of a device relative to acoustically reflective surfaces. The device emits an audible sound containing a frequency-modulated signal and captures the reflections of that sound. This technology enables the device to determine the amplitude of reflections at different time-of-arrivals, which corresponds to the direction of the reflection. By performing beamforming, the device can generate a 2D intensity map illustrating the intensity of reflections at each spatial location around it, thus detecting nearby walls.

Another notable patent is for "Controlling sensitivity of presence detection using ultrasonic signals." This patent outlines techniques for presence-detection devices to adjust their sensitivity based on varying types of movements, such as major movements like walking or minor movements like typing. The devices emit ultrasonic signals and utilize changes in frequency, or Doppler shifts, to detect movement. By varying the presence-detection sensitivity, these devices achieve improved accuracy in recognizing the presence of users within an environment.
