Abstract: A compressed gas regulator of a piston type is disclosed in which a regulator is configured with an input valve situated entirely inside a compressed air canister, which regulator is then attached to a paintball gun, marker or other device for providing discrete charges of gas at a predetermined pressure to the attached device. The overall size and weight of the regulator are minimized, which allows increased capabilities to the user. A regulator overpressurization port vents behind a conventional safety gauge for safety purposes. Fill, gage, and canister overpressurization rupture ports are interconnected with a fill channel that extends from the canister to the ports without intersecting or interfering with the regulating components within the regulator. The input valve seat face is surrounded by a shallow generally conical surface within an input plenum. The shallow generally conical surface extends at approximately 5 to 15 degrees.

Abstract: A method and apparatus, including software, for the development and operational use of precise utility location and utility asset management information. Field-usable data sets may be produced that meet standards of accuracy and usability that are sufficient for use by field operations personnel participating in damage prevention activities associated with ground penetrating projects (e.g., excavating, trenching, boring, driving, and tunneling) or other asset applications. Some embodiments relate to integrating utility asset data including coordinate location, and geographical information data using a consistently available and accurate coordinates reference for collecting the data and for aligning the geographical information data. Some embodiments relate to managing projects with equipment that provides real time images and the updating of the data as required with this desired accuracy.

Abstract: A system for data communication in a space illuminated by a plurality of illumination sources that are powered by a common power feed. The system includes a power modulation unit which is interposed in the common power feed, upstream of each of the illumination sources. The power modulation unit induces a change in the signal of the power feed in response to received data and effects variations in illumination intensity in the space provided by the illumination sources. The data is provided by a data source computer. At least one optical receiver is in the illuminated space and is in optical communication with at least one of the illumination sources. The optical receiver is responsive to changes in the incident light from the illumination sources resulting from the power modulation unit. The system can be used to communicate and display product data in an electronic shelf tag system.
