The invention is directed to techniques for delivering a capsule for sensing acidity to a location along the esophagus via a delivery device that detects pressure variations to identify a lower esophageal sphincter. The methods include determining a row addressing order based on an attribute of the image data that minimizes the number of column charging transitions necessary to write the image data to the display. Each of the first to nth slave chip ID generating units is configured to add a predetermined code value to an mth operation code to generate an th operation code. The motive device may include a single cylinder for performing both the locking and latching function. Depth of an video may be estimated by extracting feature information from the input video, and estimating the depth of the input video based on the extracted feature information. The closure includes a lid and a tear strip formed to include a finger-pull tab and coupled to the lid along a frangible tear line.
