Abstract: A projection device for displaying construction plans comprises a projector head having projection optics, a laser module, a first mirror galvanometer redirecting incident light from the laser module toward a second mirror galvanometer that redirects further the incident light toward the projection optics. A memory device stores one or more construction plans. A controller operatively connected to the laser module, the two mirror galvanometers, and the memory device chooses a construction plan to be displayed from the memory device, selectively activates the laser module, and selectively causes the first and second mirror galvanometers to follow a path defined by the chosen construction plan concurrently with the selective activation of the laser module so that the incident light redirected toward the projection optics selectively forms a projection of the construction plan on a construction site.

Abstract: The system includes a first reactor configured to discharge CO2 depleted process gas. The first reactor having a first and a second portion of particulate sorbent material having captured CO2. A second reactor is arranged to receive the first portion of particulate sorbent material and is configured to release CO2 from the particulate sorbent material by decarbonation, return the first portion of particulate sorbent material to the first reactor, and discharge a CO2 rich gas stream. A third reactor is arranged to receive the second portion of particulate sorbent material and is configured to supply water to the second portion of particulate sorbent material to hydrate at least a part of a remaining portion of calcium oxide of the second portion of particulate sorbent material to form calcium hydroxide, and return the second portion of particulate sorbent material to the first reactor.
