Patent number: 11964436Abstract: In an example, a method includes operating, by a processor, on object model data and operating, on a processor, on pattern data. The object model data describes at least part of an object to be generated in additive manufacturing and the pattern data describes an object pattern intended to be formed on at least a portion of the part of the object to be generated in additive manufacturing. The method includes determining, by a processor, control data to control a print agent applicator to apply a pattern of fusing agent onto a part of a layer of build material. The pattern of fusing agent comprises a fusing agent area and a gap area that lacks fusing agent. The gap area corresponds to the object pattern such that no fusing agent is applied to a part of the layer of build material that corresponds to the object pattern.Type: GrantFiled: December 20, 2022Date of Patent: April 23, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Wei Huang, Gary J. Dispoto, Craig Peter Sayers

Patent number: 11966309Abstract: One aspect provides a method and system for saturation of multiple I/O slots by multiple testing ports and verification of link health in between. During operation, the system detects a testing card with a plurality of test ports which are coupled to a plurality of input/output (I/O) slots of a computing device. The system communicates with the plurality of test ports via the plurality of I/O slots. The system generates, by the computing device, a script for each test port, wherein the script comprises a series of read and write operations to be executed by the testing card on a memory device associated with the computing device. The system allows the plurality of test ports to execute the script and perform the corresponding read operations and write operations, thereby facilitating testing of the I/O slots of the computing device in parallel by the test ports of the single testing card.Type: GrantFiled: June 30, 2022Date of Patent: April 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Hong-Jen Hsu, Chih-Kang Lin

Patent number: 11966475Abstract: A method includes accessing an input representing a software component list for a software product. The software component list contains information for a given software component. The method includes accessing a knowledge base to determine security level parameters and trust parameters for the given software component based on the information. A security level of the given software component is determined based on an evaluation of the security level parameters. A trust of a source of the given software component is determined based on an evaluation of the trust parameters. The method includes determining a security context of the software product. Based on the security level, the trust and the security context, the method includes providing a recommendation for the given software component.Type: GrantFiled: October 26, 2020Date of Patent: April 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Suhas Shivanna, Matthew Yang, Craig Rubin

Patent number: 11968512Abstract: In an example, a speaker device may include a first transducer and a second transducer. The first transducer may include a first diaphragm, a first magnetic circuit, and a first voice coil disposed in a magnetic gap of the first magnetic circuit to cause vibration of the first diaphragm. The second transducer may include a second diaphragm, a second magnet circuit, and a second voice coil disposed in a magnetic gap of the second magnetic circuit to cause vibration of the second diaphragm. Further, the speaker device may include a magnetic plate having a first surface coupled to the first transducer and a second surface coupled to the second transducer. The first surface is opposite to the second surface.Type: GrantFiled: June 22, 2022Date of Patent: April 23, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Yen-Hsin Ho, Yi-Ying Lai, Chen-Hui Hu, Chen-Yu Chang

Patent number: 11968116Abstract: Methods and systems are provided for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform per-flow packet dropping and ECN marking.Type: GrantFiled: March 23, 2020Date of Patent: April 23, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Jonathan P. Beecroft, Anthony Michael Ford
