Abstract: A building system including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to ingest information comprising at least one of occupancy information or energy usage information associated with a building. The instructions further cause the one or more processors to generate a space usage recommendation based on the information. The instructions further cause the one or more processors to cause a graphical model of the building to include a representation of the information and the space usage recommendation. The instructions further cause the one or more processors to cause a display device of a user device to display the graphical model within a user interface.

Abstract: A process for start up of a thermal ink-jet printhead cartridge that includes a sequence of nozzle clearing procedures of increasing severity which are performed in sequence so long as some of the nozzles of the printhead fail to fire ink drops pursuant to ink firing pulses provided to the printhead or until all of the procedures have been performed.

Abstract: Sets of radially mounted solid ink spark jet capsules are situated around the circumference of a cylindrical drum rotated at high speed. A commutation disc, mounted on one end of the drum, has a surface with spaced concentric conductive strips. Each strip corresponds to a different one of the capsules in each of the sets. The strips are divided into arcuate sections, one section for each set. The sections are aligned in groups. A line of stationary contacts, one for each of the strips, energize sections in the group aligned therewith when connected through electrical switches to a pulsed high voltage source. The mechanical commutator significantly reduces the number of electrical switches required. A single motor rotates the drum, as well as print speed and slew speed capstans.
