Hewlett Packard Patents by Type
  • Patent number: 11909671
    Abstract: A system for facilitating efficient port reconfiguration at a switch is provided. During operation, the system can identify a target port of the switch for reconfiguration based on one or more reconfiguration parameters indicating how a set of logical ports are generated from the target port. The system can disable the target port at the control plane of the switch, which disables features provided to the target port from the control plane. The control plane can provide a set of features supported by the switch at a port-level granularity for facilitating operations of the switch. The system can then configure the forwarding hardware based on the reconfiguration parameters to accommodate the set of logical ports. When the reconfiguration of the target port is complete, the system can enable a respective logical port at the control plane, which enables one or more features for the logical port from the control plane.

  • Patent number: 11910249
    Abstract: Systems and methods are provided for optimizing resource consumption by bringing intelligence to the key allocation process for fast roaming. Specifically, embodiments of the disclosed technology use machine learning to predict which AP a wireless client device will migrate to next. In some embodiments, machine learning may also be used to select a subset of top neighbors from a neighborhood list. Thus, instead of allocating keys for each of the APs on the neighborhood list, key allocation may be limited to the predicted next AP, and the subset of top neighbors. In some embodiments, a reinforcement learning model may be used to dynamically adjust the size of the subset in order to optimize resources while satisfying variable client demand.

  • Patent number: 11904598
    Abstract: A conditioner includes a pressure roller assembly, a tension roller assembly, a heating element, a pressure roller drive motor, a tension drive motor, and a controller. The heating element heats the pressure roller assembly. The pressure roller drive motor rotates the pressure roller assembly. The tension drive motor rotates the tension roller assembly. The controller receives a print job complete notification to initiate a conditioner shutdown. In response to the print job complete notification, the controller turns off the tension drive motor. The controller sets the heating element to a predetermined temperature and waits a first predetermined period. In response to the first predetermined period elapsing, the controller turns off the heating element. With the heating element turned off, the controller turns off the pressure roller drive motor.

  • Patent number: 11902150
    Abstract: System and methods are described for providing adaptive routing in the presence of persistent flows. Switches in a fabric have the capability to establish flow channels. Switches can adaptively route flows, while monitoring transmission characteristics of the flows channels to identify whether any flows are experiencing congestion towards a destination. In response to detecting congestion, it can be further determined whether the flow is related to a source of congestion, or alternative the flow is a victim of congestion. Flows that are a source of congestion have their routing constrained to prevent congestion from propagating. For example, new packets of a flow that is a source of congestion may be forced to only take the path of the data transmission that detected said congestion (preventing congestion from spreading). Alternatively, victims of congestion do not have their routing constrained, and packets can take any path as permitted by adaptive routing.

  • Patent number: 11892786
    Abstract: An image heating device includes a conveyance belt having a heat generation layer, and a first electrode portion, a second electrode portion and a third electrode portion that are in contact with the heat generation layer. The conveyance belt conveys a recording medium that includes an image. A first heat generation region formed on the conveyance belt between the first electrode portion and the second electrode portion generates heat to a first temperature that is equal to or greater than a deformation temperature at which a material forming the image is deformable. A second heat generation region formed between the second electrode portion and the third electrode portion generates heat to a second temperature that is different from the first temperature. The first heat generation region and the second heat generation region are located in a region of the conveyance belt to contact the recording medium.

  • Patent number: 11892787
    Abstract: A fixing device includes a belt having a tubular shape and extending in a longitudinal direction, and having a longitudinal end, a drive roller to rotate the belt to convey a print medium between the drive roller and the belt, a bushing located at the longitudinal end of the belt, and a guide wall adjacent to the bushing. The belt is displaceable in the longitudinal direction relative to the bushing. The bushing includes a shoulder adjacent to the longitudinal end of the belt and a stem extending from the shoulder to an inside of the belt to support the belt. The guide guides the bushing to move in a direction opposite to a conveyance direction of the print medium when the belt moves toward the bushing. The stem of the bushing includes a convex portion that is in contact with an inner surface of the belt when the belt is displaced in the longitudinal direction.

  • Patent number: 11892965
    Abstract: In an example in accordance with the present disclosure, a system is described that includes a hub for routing data traffic between a first computing device and a second computing device. A detection device of the system detects a communication protocol between the computing devices. A switch of the system routes traffic directly between the computing devices when a first communication protocol is detected. When a second communication protocol is detected, the switch re-routes traffic of the first type from the first computing device back to the hub to convert the traffic of the first type to a second type and routes converted traffic directly to the second computing device.

  • Patent number: 11893962
    Abstract: In one example in accordance with the present disclosure, a computing device is described. The computing device includes a number of ports. Each port receives a connection to a display device. A first port is coupled to the first graphics processor which supports a number of display devices and a second graphics processor. The computing device also includes a controller. The controller determines when a number of coupled display devices is greater than the number of display devices supported by the first graphics processor and switches the first port from being driven by the first graphics processor to be driven by the second graphics processor.
