  • Patent number: 11818943
    Abstract: Organic light-emitting diodes are disclosed comprising an electron transport layer and a hole transport layer. At least one of the transport layers is formed by (a) dissolving tubulin or microtubules in a mixture of water and a solvent that changes the surface charge of tubulin, wherein the percentage of solvent in the mixture is selected so that the tubulin acquires a desired surface charge, and (b) using the tubulin with the desired surface charge to fabricate the at least one of the transport layers. Advantageously, the solvent may be DMSO. Methods of fabricating such organic light emitting diodes are also disclosed.

  • Publication number: 20230153156
    Abstract: Synchronizing system resources of a multi-socket data processing system can include providing, from a primary System-on-Chip (SOC), a trigger event to a global synchronization circuit. The primary SOC is one of a plurality of SOCS and the trigger event is provided over a first sideband channel. In response to the trigger event, the global synchronization circuit is capable of broadcasting a synchronization event to the plurality of SOCS over a second sideband channel. In response to the synchronization event, the system resource of each SOC of the plurality of SOCS is programmed with a common value. The programming synchronizes the system resources of the plurality of SOCS.

  • Patent number: 11475064
    Abstract: A method in a database system is disclosed. The method comprises generating a task template object from a platform entity with polymorphic lookup capability that can map to multiple tenant domains wherein the task template object contains one or more task completion storage records for storing task-specific information, converting the task template object into a work-type object by storing task-specific information in the one or more task completion storage records wherein the work-type object comprises a work-type object identifier (ID), a first record for recording the database ID of one or more work order objects mapped to the work-type object, and a first task completion storage record for storing a first type of task-specific information. The method further comprises generating a work order object for a task and providing the work order object with access to the task-specific information by linking the work-type object to the work order object.

  • Publication number: 20190182202
    Abstract: A multi-chassis link aggregation (MC-LAG) system includes one or more dual homed nodes coupled to a pair of switches (MC pair) and one or more single homed nodes coupled to a single one of the MC pair of switches. The MC pair of switches advertises a virtual IP address for the dual homed nodes such that traffic may be received at either switch in the MC pair for the dual homed nodes. For a single homed node, a dedicated IP address is advertised associated with a switch in the MC pair locally connected to the single homed node. Traffic destined to the single homed node is thus transmitted to the switch in the MC pair locally connected to the single homed node.
