Publication number: 20220355237Abstract: Deleterious gas is captured from atmospheric air using capture units dispersed across a geographic region. Each unit has a filter that is capable of capturing compounds from the gas from air when air is passed through the filter by fans. The units additionally include a sensor for sensing a level of the gas in the air. An electronic processor controls the fan, and communicates data from the sensor to other units and/or a central electronic processor. The electronic processors of the units or the central processor controls the fan speed of units in areas of higher concentration of the gas, selecting which units to become active based upon a proximity of each unit to the gas concentration, as well as a direction of movement of the concentration. A communicated presence of errors or a low battery state of a unit, is used by the processor to select other units nearby for operation instead of the affected unit.Type: ApplicationFiled: April 14, 2022Publication date: November 10, 2022Applicant: Kevin L.

Publication number: 20210132609Abstract: An autonomous vehicle is configured to move across a floor surface in an environment. The autonomous vehicle includes a proximity sensor that is positionable at different heights on the autonomous vehicle. A location of the autonomous vehicle within the environment is determined. A proximity sensor height is determined based on the location of the autonomous vehicle within the environment. The proximity sensor is positioned at a height on the autonomous vehicle based on the proximity sensor height. A signal is received from the proximity sensor where the signal is indicative of a distance to an object within the environment at the height of the proximity sensor on the autonomous vehicle. An operation of the autonomous vehicle can be controlled based on the signal indicative of the distance to the object.Type: ApplicationFiled: March 9, 2018Publication date: May 6, 2021Inventors: Stephen D.
