Abstract: In embodiments, a first resource is produced for a first dataset having a time indicator, by applying a first digital rule. A first notification can be caused to be transmitted about an aspect of the first resource to a remote device. A second dataset can be stored, which has values derived from the first dataset, and encodes a parameter of the first resource. A second digital rule may be stored to replace the first digital rule, at an updating time (Tupd). The second digital rule may have an effective time (Teff) prior to the actual updating time Tupd. A second resource may be produced by applying the second digital rule. A second notification can be caused to be transmitted about an aspect of the second resource to a remote device.

Abstract: A method includes attaching a gas capture device to a bypass system adjacent to a gas meter. The method also includes rotating an internal cartridge near the gas meter to a bypass mode. The rotation of the internal cartridge enables gas to be diverted through a bypass system and away from the gas meter into an outlet. Remaining gas is captured from the gas meter to prevent the gas from releasing externally. The gas meter is removed from its original position. The internal cartridge is rotated from the bypass mode to a purge mode.
