  • Apparatus, system and method for detecting defects in building structures
    Patent number: 9790688
    Abstract: An apparatus, system and method for detecting defects in building structures is provided. The apparatus includes a detector operable to determine an indication of the defect; and a transmitter operable to wirelessly transmit the indication from the apparatus to a central controller. The system includes the detection unit; a locator operable to determine the location of the detection unit; and a memory for storing the indication and the location in association with each other. The memory may be part of a central controller in wireless communication with the detection unit. The apparatus or central controller may include a processor operable to determine from a plurality of measurements performed by the detection unit a resultant measurement vector indicating a direction from the detection unit toward the defect. The detection unit may be operable to autonomously change its location. A display showing resultant measurement vectors at various locations can be produced.
