Abstract: An unmanned aerial vehicle (UAV) recovery system comprises a base and a pneumatic capture net, including a set of upwardly extending, flexible, inflatable tubes, supported by a capture net support assembly. Drag forces are exerted on a UAV by the set of tubes when the UAV flies into them. In some examples the recovery system includes a plurality of decelerators, each decelerator having a supply of a restraint strap, connected to the pneumatic net, which can be pulled from the decelerator upon the application of a sufficient force so that movement of the pneumatic net is resistible by forces exertable by the decelerators on the pneumatic net.

Abstract: A method and apparatus for using a persistent message store in a distributed computing system. A message is stored in a persistent message store, wherein the message is a copy of an original message transmitted from a message producer to a message consumer in a distributed computing system. A command is received from a requestor to search the persistent message store for a stored message, the command indicating a search rule. The search rule is processed by a rules engine of the persistent message store to search for the stored message.

Abstract: A printing system includes a rotatable transport member that transports a receiver on its obverse. A tackdown unit includes an electrode arranged facing the reverse of the transport member. A source responsive to the control system produces a tackdown current, and a charger spaced apart from the transport member facing the obverse thereof selectively deposits charge on the receiver in response to the tackdown current. A non-contact voltmeter arranged facing the receiver on the obverse after the charger measures a resulting voltage. A control system drives a selected voltage or current through the charger using the source and measures a resulting voltage using the non-contact voltmeter. The selected voltage or current and the measured resulting voltage are used to automatically estimate a capacitance of the receiver.

Abstract: A processing device receives a message identifier associated with an application. and identifies a first language that an operating system running on the processing device is configured to use. Responsive to determining that a first application resource bundle associated with the application and configured for the first language is not available, the processing device selects a second application resource bundle that is associated with the application and configured for a second language, identifies a first version of a message associated with the message identifier in the second application resource bundle, sends the first version of the message to an automated translator with a request to translate the first version of the message to the first language, and receives a first translated version of the message that is in the first language. The processing device may then present or store the first translated version of the message.

Abstract: A method for producing a raised print on a receiver includes receiving image data and height data. The height data specify that raised printing should be produced in non-first-color region of the image data.

The separation data for the clear toner is determined in response to the height data and the separation data for the light toner is determined in response to the image data and the height data so that the clear and light-toner separations specify that respective toners be deposited one atop the other in the non-first-color region. Respective toner images are deposited on the receiver, each corresponding to respective separation data. The deposited toner is fixed to the receiver member.

Abstract: A transfer unit includes a rotatable static-dissipative member with a time-varying electrical property. A second member selectively transfers toner to or from the static-dissipative member. A power source selectively produces an electrostatic transfer field between the static-dissipative member and the second member, so that toner is transferred between the static-dissipative member and the second member. A charger spaced apart from the static-dissipative member selectively deposits charge thereon. A control system successively drives a plurality of different selected voltages or currents through the charger and measures a plurality of respective resulting charger currents or voltages. It uses the selected voltages or currents and the respective charger currents or voltages to automatically estimate a variation in the electrical property. It then causes the power source to produce an electric transfer field that transfers toner and compensates for the estimated variation.

Abstract: An electrophotographic (EP) printer for transferring a toner image to a receiver sheet has a tensioned rotatable transport web with a Young's modulus of at least 1 GPa. The transport web is wrapped around a compliant image-bearing member. A compressible, rotatable nip-forming member that is relatively less stiff than the image-bearing member is adjacent to the transport web on the opposite side thereof from the image-bearing member. A mount holds the nip-forming member against the image-bearing member, and permits the axis of rotation of the nip-forming member to move closer to or farther from the transport web. When the leading edge of the receiver on the web engages with the image-bearing member, the nip-forming member compresses. The axis of rotation of the nip-forming member translates by an amount less than the thickness of the receiver sheet minus the compression of the compliant coating of the image-bearing member.

Abstract: Apparatus for electrically reconditioning a rotatable photoreceptor in an electrophotographic (EP) printer includes a charger, an exposure subsystem, a transfer station, and an erase lamp arranged in that order around the photoreceptor in the direction of rotation thereof. A first corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, between the transfer station and the erase lamp. The transfer station and the erase lamp are at most 1 cm apart. A second corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, after the erase lamp in the direction of rotation of the photoreceptor. The erase lamp and the second corona electrode are less than 1 cm apart.

Abstract: An electrophotographic photoreceptor is prepared for charging. Corona electrodes before and after the erase lamp apply respective biases to provide the correct sign of charge for cleaning, and to discharged trapped charges in the photoreceptor. Toner is then cleaned off the photoreceptor. This leaves the photoreceptor electrically and mechanically reconditioned and ready for its next printing cycle.

Abstract: A computing device sends a message to a destination node. Upon failing to receive a message response from the destination node, the computing device sends a query to a plurality of additional nodes, wherein the query causes the additional nodes to attempt to communicate with the destination node and to forward the query to other additional nodes if the attempt to communicate with the destination node fails. Further, the computing device receives a query response from an additional node of the plurality of additional nodes, the query response indicating that the additional node can communicate with the destination node, and uses the additional node as a proxy for communicating with the destination node.

Abstract: A processor records statistics regarding invocation of a second component of a distributed computing system by a first component of the distributed computing system. The processor determines a dependency between the first component and the second component based on the statistics and determines a dependency rating for the dependency based on the statistics. The processor migrates the first component from a first location to a second different location. Responsive to determining that the dependency rating for the dependency exceeds a dependency threshold, the processor migrates the second component to the second location.
