Abstract: A meter readout on a meter has digits including a first digit, a second digit, etc. A sequence of images of the meter is obtained. The images include images of the digits in the meter readout. Automated recognition of the digits in the images result in likelihood arrays indicating the likelihoods for the digit values for the digits imaged in the meter images. Short chains of digit values are identified and spliced together to form a series of single digit, two-digit, three-digits, etc. paths that are built up based on the likelihood arrays. Various criteria are used to discard most of the chains and thereby avoid the combinatorial explosion of possible paths and thereby produce reliable meter readings without consuming considerable computational resources.

Abstract: A method for remotely measuring pressure of a fluid in a container includes determining a spatial location of first and second resonant radiofrequency antenna elements located on a radiofrequency identification (RFID) tag located in the container. The first antenna element is positioned in a fixed position on the RFID tag and the second antenna element is positioned on a deformable element configured to be deformed in at least one dimension based on pressure from the fluid. The spatial location is determined from a radar image generated based on reflected radiofrequency beams from a scan area and re-radiated radiofrequency beams from the first and second antenna elements located within the scan area. A pressure value is determined for the fluid based on the spatial location of the first and second antenna elements. Systems and methods of remotely measuring pressure using passive RFID tags are also disclosed.
