  • Patent number: 11097433
    Abstract: A robotic device comprising a long-range sonar assembly configured to detect objects between 1000 mm to 9500 mm from the long range sonar assembly. The long-range sonar assembly comprises a flared bell housing and a transducer. The robotic device also comprises a transportation mechanism configured to move the robotic device in various directions in response to instructions from a processing device that is in communication with the ling-range sonar assembly and the transportation mechanism. The processing device may cause the long-range sonar assembly to, via the transducer transmit one or more pulses and receive the one or more pulses as echo pulses having reflected off an object in an environment. The processing device may then cause a transmitter to transmit instructions to the transportation mechanism to move the robotic device in the environment based on the received one or more pulses.

  • Patent number: 11007294
    Abstract: Provided is a method and an apparatus for indicating minimum exposure of a surface to UVC light emitted by a source during a decontamination process to achieve a desired level of pathogen reduction. The apparatus includes a photochromic material to be applied to, or applied adjacent to the surface. The photochromic material is to exhibit a visible response to receiving the minimum exposure to the UVC light, and exhibit the visible response to a lesser extent after the photochromic material ceases to be exposed to the UVC light emitted by the source. A protective layer of material that is substantially transparent to the UVC light emitted by the source is positioned over the photochromic material to be disposed between the source and the photochromic material during the decontamination process.
