  • Patent number: 11850842
    Abstract: A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising air flow guide structure extending into the opening of the carrier plate between the carrier plate and the printhead to flow air through the opening. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

  • Patent number: 11856419
    Abstract: Methods and systems to commission building environmental sensors are disclosed. The system include a device that will move about the environment of a building (inside and/or outside) and detect building environmental sensor devices that are installed in the environment. For each of the sensor devices, in response to detecting the sensor device, the system will retrieve an identifier for the sensor device, and it will determine whether the sensor device is registered with a control system. If the sensor device is registered with the control system, the system will not automatically implement a commissioning process with the sensor device. If the sensor device is not registered with the control system, the system will automatically implement the commissioning process with the sensor device.

  • Patent number: 11840784
    Abstract: An addition to additive manufacturing sews a number of printed substrate sheets together using industrial sewing machine technology. Portions of the final 3D object that will be solid are sewn together into bundles of the object with a needle protruding through the top of the bundle via a sewing machine with a looping mechanism connecting the thread loops under each bundle of printed substrate sheet layers. This will result in many well connected stack bundles that are then stacked in alignment to form the final stack. During heat and compression, the stitch thread may bunch together and become entangled with the cooled plastic of the final solid 3D object. Removal of the excess substrate may proceed as usual, since the sewing is applied only in the solid portions of the final object. The end result will be a part with much higher strength in the Z axis.

  • Patent number: 11833810
    Abstract: A printing system comprises a media transport device which holds print media, such as paper, against a movable support surface, such as a belt, by vacuum suction through holes in a vacuum platen and transports the print media though a deposition region of one or more printheads, which deposit a print fluid, such as ink, on the print media. The printing system comprises an airflow control device comprising dampers that are moveable along a direction perpendicular to the vacuum platen between an undeployed configuration and a deployed configuration, each damper blocking at least one row of the holes in the deployed configuration. The airflow control device also comprises actuators to move the damper(s). The actuator(s) are controlled to selectively move the damper(s) between the undeployed and deployed configuration based on a position of an inter-media zone between adjacent print media held against the movable support surface.
