A modular electronic utility meter has a sensor portion that includes sensor devices and a memory device storing calibration andor error information specific to the sensor devices. To protect privacy, a caricature or cartoon of an individual can he placed on an obverse face, or in a virtual card, wallet or purse, which image cannot be read by facial recognition techniques but could be recognized by human observers. Hydrogen handling equipment may include a hydrogen generator, a pressurizing apparatus or compressor, pressure vessels, piping, valves, vent pipes, andor a dispenser. The apparatus and method enhances the attractiveness of the artificial breeding pool to the gravid insects and helps control the local insect population. In the second operating mode, a second laser head is activated by means of an optical scanner system and directs the laser pulses onto a two-dimensional pulse area on the surface of the workpiece, the material removal is accomplished by laser ablation. Additionally, the apparatus and method of the present invention is drawn to a gathering means whereby algal turf or biomass is severed from the ATS and transferred via a towing method, instead of pushing, thereby reducing potential damage to the ATS.
