  • Patent number: 10957733
    Abstract: A method of assembling a photodetector assembly includes depositing bumps on a read out integrated circuit (ROIC) without depositing bumps on a photodiode array (PDA). The method includes assembling the PDA and ROIC together wherein each bump electrically interconnects the ROIC with a respective contact of the PDA. A photodetector assembly includes a PDA. A ROIC is assembled to the PDA, wherein the ROIC is electrically interconnected with the PDA through a plurality of electrically conductive bumps. Each bump is confined within a respective pocket between the ROIC and a respective contact of the PDA. The disclosed methods can enable focal plane array manufacturers to achieve low-cost production of ultra-fine pitch, large format imaging arrays.

  • Patent number: 10923152
    Abstract: Technologies are provided for partially updating shingled magnetic recording (SMR) zones in SMR storage devices. An SMR storage device can receive and process a command to update a write pointer for an SMR zone to point to an arbitrary write position within the SMR zone. A partial SMR zone update command can be received and processed to modify part of the data stored in the SMR zone. A write position within the SMR zone where data to be modified is stored can be identified. Data stored in the SMR zone following the identified write position can be read to a temporary location and modified. A write pointer for the SMR zone can be updated to point to the identified write position. The modified data can then be written to the SMR zone, starting at the write position identified by the write pointer, or to another SMR zone of the storage device.

  • Patent number: 10848346
    Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

  • Publication number: 20200310845
    Abstract: A first instance is caused to execute software code to perform a first portion of a workflow in response to receipt of a workflow request, and performance of the first portion results in submission of an operation request to an entity. A resume workflow request is received from the entity, where the resume workflow request includes a handle to a snapshot that corresponds to a state of execution of the software code and a response to the operation request to the entity. Using the handle to the snapshot and the response to the operation request, a second instance is caused to execute the software code from the first state to perform a second portion of the workflow. A workflow result is received from an instance that executes a last portion of the workflow, and the workflow is provided result in response to the workflow request.

  • Patent number: 10664508
    Abstract: Unstructured data items are stored in an item collection. An access request comprising an input interpretation rule and a filtering criterion is directed to at least a portion of the item collection. Records are extracted from an unstructured data item using the input interpretation rule. A response to the access request is obtained, based at least partly in a determination that one of the records satisfies the filtering criterion.

  • Patent number: 10650032
    Abstract: Unstructured data items are stored at an object storage service. A filtering criterion to be used to generate a result set for an access request is determined. A test that can be used to determine, without completing parsing of a record identified in an unstructured data item, whether the record satisfies the filtering criterion is identified. Parsing of a particular record is abandoned in response to determining, using the test, that the record satisfies the filtering criterion. A response to the access request is determined using a subset of records that satisfy the filtering criterion.

  • Patent number: 10623319
    Abstract: A load shedding mechanism and an endpoint selection mechanism may be used to rebalance loads of endpoints of a network-based service. The load shedding mechanism may monitor health information of one or more endpoints and determine whether to perform a load shedding operation based on the health information. In response to determining to perform the load shedding operation for a selected endpoint, the load shedding mechanism may, prior to a client close request for a keep-alive connection of the selected endpoint, trigger an early close of the keep-alive connection. In response to a corresponding client attempting to reconnect based at least in part on the early close, the endpoint selection mechanism may select another endpoint to form a keep-alive connection with the client.

  • Patent number: 10589086
    Abstract: An apparatus for providing deep nerve stimulation to a patient includes a housing for supporting deep nerve stimulation coils. The housing includes a wall with an outer surface for being presented toward the patient to apply the stimulation. A primary coil is supported in a primary chamber of the housing adjacent an inner surface of the wall, opposite the outer surface. Ribs are disposed between the primary coil and the inner surface and upon which the primary coil rests. The ribs define channels through which coolant can be directed to cool a bottom surface of the primary coil during use, the bottom surface of the primary coil being closest to the patient side wall. The primary coil is adapted when energized to produce a broad and deeply penetrating magnetic field capable of hitting a target area of the patient.
