摘要： An optical gloss meter above an imaging member surface measures fountain solution surface gloss on the imaging member surface in real-time during a printing operation. The measured gloss corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

摘要： A three-dimensional (3D) metal object manufacturing apparatus is equipped with a removable vessel to reduce the time required for start-up procedures after the printer is serviced. The removable vessel is filled with solid metal that is heated to its melting temperature before the bulk wire is inserted into the vessel to commence printing operations. The melting of the solid metal in the removable vessel requires less time that the melting of an length of bulk wire adequate to produce a volume of melted metal suitable for printer operation. The solid metal in the removable vessel can be metal pellets, metal powder, or a solid metal insert.

摘要： Pigmented polymer particles may comprise a thermoplastic polymer and a pigment, wherein at least some of the pigmented polymer particles have a morphology according to (a), (b), (c), or any combination thereof: (a) the pigment having a coating comprising the thermoplastic polymer and the coated pigment adhered to a thermoplastic polymer particle, (b) the pigment being embedded in an outer surface of the thermoplastic polymer particle, and (c) the pigment being encapsulated by the thermoplastic polymer particle. The pigmented polymer particles, especially the highly spherical pigmented polymer particles, may be useful, among other things, as starting material for additive manufacturing. For example, a method may comprise: depositing, upon a surface, the foregoing pigmented polymer particles optionally in combination with other thermoplastic polymer particles; and once deposited, heating at least a portion of the particles to promote consolidation thereof and form a consolidated body.

摘要： A method for operating a three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form vias in substrates. The method identifies the bulk metal being melted for ejection and uses this identification data to select the operational parameters. The method identifies the via holes in the substrate and operates an actuator to position an ejector opposite the via holes to eject drops of melted bulk metal toward the via holes to fill the via holes.

摘要： A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.

摘要： A multi-function device (MFD) is disclosed. For example, the MFD includes, a communication interface to establish a communication session with other MFDs within a community of MFDs, a processor, and a non-transitory computer readable medium storing instructions, which when executed by the processor, cause the processor to determine a feature of the MFD is operating incorrectly, transmit a help message to the other MFDs within the community of MFDs, receive a configuration file for the feature that is operating incorrectly from a second MFD within the community of MFDs that has a health status of fully operational, upload the configuration file, determine the feature is operating correctly after the configuration file is uploaded, and update a health status of the MFD to fully operational.
