  • Patent number: 9895899
    Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. A housing defines an interior having a pair of opposed electrodes. The electrodes have a capacitance that varies in response to an amount of liquid between them. A controller energizes one electrode and receives an output reading from the other. The controller processes the reading on board the housing and supplies it as a digital data stream to the imaging device during use. A memory stores calibration values for an empty and full housing. The controller writes back to the memory present fluid levels obtained from the output reading of the electrode. An enable output allows operation or not of a fluid pump in the imaging device. Materials, construction, modularity, and fluid communication ports are further embodiments, to name a few.

  • Patent number: 9896758
    Abstract: A physical vapor deposition (PVD) chamber for depositing a transparent and clear hydrogenated carbon, e.g., hydrogenated diamond-like carbon, film. A chamber body is configured for maintaining vacuum condition therein, the chamber body having an aperture on its sidewall. A plasma cage having an orifice is attached to the sidewall, such that the orifice overlaps the aperture. Two sputtering targets are situated on cathodes inside the plasma cage and are oriented opposite each other and configured to sustain plasma there-between and confined inside the plasma cage. The plasma inside the cage sputters material from the targets, which then passes through the orifice and aperture and lands on the substrate. The substrate is moved continuously in a pass-by fashion during the process.

  • Patent number: 9893951
    Abstract: In general, techniques are described for dynamically scheduling and establishing paths in a multi-layer, multi-topology network to provide dynamic network resource allocation and support packet flow steering along paths prescribed at any layer or combination of layers of the network. In one example, a multi-topology path computation element (PCE) accepts requests from client applications for dedicated paths. The PCE receives topology information from network devices and attempts to identify paths through a layer or combination of layers of the network that can be established at the requested time in view of the specifications requested for the dedicated paths and the anticipated bandwidth/capacity available in the network. The PCE schedules the identified paths through the one or more layers of the network to carry traffic for the requested paths. At the scheduled times, the PCE programs path forwarding information into network nodes to establish the scheduled paths.

  • Publication number: 20180013821
    Abstract: Presented herein are techniques for use in a network environment that includes one or more service zones, each service zone including at least one instance of an in-line application service to be applied to network traffic and one or more routers to direct network traffic to the at least one service, and a route target being assigned to a unique service zone to serve as a community value for route import and export between routers of other service zones, destination networks or source networks via a control protocol. An edge router in each service zone or destination network advertises routes by its destination network prefix tagged with its route target. A service chain is created by importing and exporting of destination network prefixes by way of route targets at edge routers of the service zones or source networks.

  • Publication number: 20180013638
    Abstract: Presented herein are techniques performed in a network comprising a plurality of network nodes each configured to apply one or more service functions to traffic that passes the respective network nodes in a service path. At a network node, an indication is received of a failure or degradation of one or more service functions or applications applied to traffic at the network node. Data descriptive of the failure or degradation is generated. A previous service hop network node at which a service function or application was applied to traffic in the service path is determined. The data descriptive of the failure or degradation is communicated to the previous service hop network node.

  • Patent number: 9861623
    Abstract: The present invention provides methods for treatment of a RAS-positive disease, in particular KRAS-positive non-small cell lung cancer as well as a method for potentiating the apoptotic activity of a PDE? inhibitor by combining the PDE? inhibitor with a direct autophagy inhibitor. The PDE? inhibitor is preferably, but not exclusively, deltarasin, and the direct autophagy inhibitor is in particular 3-methyladenine. Further provided by the present invention are a kit and a pharmaceutical composition comprising the PDE? inhibitor and a direct autophagy inhibitor. The methods of the present invention in particular provide a new treatment option for RAS-positive diseases such as KRAS-positive non-small cell lung cancer allowing for an increased apoptotic activity of the PDE? inhibitor by simultaneously blocking its “tumor protective” autophagy.

  • Publication number: 20170364984
    Abstract: The improved data management system includes a computerized database device for capturing item technical data provided and maintained by a vendor. A digital representation of the item, for example, a linear or matrix code, ASCII, image, or video data is associated with the technical data. An end user interface utilizes a camera on the end user's smart phone, tablet device, or other computing device to generate image related data of an item of interest for correlation with the digital representation, and is utilized by the database to look up and present the technical data associated with the item of interest. An enhancer interface allows the addition and maintenance of enhancement data to be associated with item technical data and presented to an end user when considering an item of interest.

  • Publication number: 20170348137
    Abstract: A system for anal and/or stomal irrigation comprises a reservoir (102) for an irrigating liquid, a catheter (100) comprising a catheter tip for insertion into the rectum or stoma of a user and for expelling of the irrigating liquid from the catheter tip, and a tubing system (121) providing a conduit for the irrigating liquid between the reservoir and the catheter tip. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a control system (103) controls a flow condition, such as the amount of liquid expelled at the catheter tip. A sensor (153) determines a measure of pressure in at least one first predetermined position in the tubing system and/or the catheter during operation of the pump, on the basis of which the flow condition is estimated. The control system is configured to control the pumping operation of the pump in response to the measure of pressure.

  • Publication number: 20170302575
    Abstract: A method for retrieving content on a network comprising a first device and a second device is described. The method includes receiving in the network a request for content from the first device, the request identifying the content using an IPv6 address for the content, and determining whether the content is stored in a cache of the second device. Upon determining the content is stored in the cache of the second device, a request is sent to the second device for the content using the IPv6 address of the content. The content is forwarded to the first device from the second device, wherein the first and second devices are part of the same layer 2 domain. Methods of injecting content to a home network and packaging content are also described.

  • Patent number: 9756124
    Abstract: In general, techniques are described for managing content request referrals by keying content requests to a composite key data structure that maps end-user address prefixes and content identifiers to content delivery network servers of downstream CDNs. In one example, a CDN exchange includes a communication module to receive first network prefixes and first content identifiers from a first secondary content delivery network and to receive second network prefixes and second content identifiers from a second secondary content delivery network. A request router of the CDN exchange redirects the content request to the first secondary content delivery network or to the second secondary content delivery network according to a network address of the end user device and a content identifier for the content request.
