  • Publication number: 20240054801
    Abstract: Images depicting items in a waste flow on a conveyor belt are provided to two analysis systems. The first system processes images to decode digital watermark payload data found on certain of the items (e.g., plastic containers). This payload data is used to look up corresponding attribute metadata for the items in a database, such as the type of plastic in each item, and whether the item was used as a food container or not. The second analysis system can be a spectroscopy system that determines the type of plastic in each item by its absorption characteristics. When the two systems conflict in identifying the plastic type, a sorting logic processor applies a rule set to arbitrate the conflict and determine which plastic type is most likely. The item is then sorted into one of several different bins depending on a combination of the final plastic identification, and whether the item was used as a food container or not. A variety of other features and arrangements are also detailed.

  • Patent number: 11893245
    Abstract: Methods, systems, and devices for multi-purpose signaling for a memory system are described. One or more signal paths of between a host device and a memory device may be configured to support shared pathways between multiple channels and to support multiple functions. For example, a signal path may be configured to communicate a state signal for an initialization sequence of the memory device, an error signal for the memory device to indicate that errors have occurred, or a low-power signal for the host device to request that the memory device enter a low-power mode, or a combination thereof. The signal path may be shared between two or more channels of the memory device.

  • Patent number: 11862202
    Abstract: Various illustrative aspects are directed to a data storage device comprising a disk and a spindle motor configured to rotate the disk wherein the spindle motor is powered by a drive voltage generated in response to a host voltage. The data storage device includes a head configured to be actuated over the disk by a head actuator and control circuitry comprising an isolation field effect transistor (ISOFET) configured to prevent a reverse current from flowing from the drive voltage to the host voltage when the host voltage falls below a threshold. The control circuitry sets a turnoff current level at which the ISOFET is directed to turn off to prevent the reverse current from flowing determines a drain-source on resistance Rdson of the ISOFET, and calculates a voltage turnoff threshold at which the ISOFET is turned off from the turnoff current level and the determined Rdson.

  • Patent number: 11837264
    Abstract: A data storage device comprises a lead actuator that actuates a first read-write head over a first disk and a support actuator that actuates a second read-write head over a second disk. A spindle motor rotates the first and second disks. In response to an emergency power off (EPO) event, a processing device retracts and parks the actuators using an internal supply voltage generated from a back electromotive force (BEMF) voltage of the spindle motor, and egresses data from a volatile to a non-volatile semiconductor memory. Egress is throttled before the actuators are retracted and parked when the internal supply voltage falls to or below a first egress throttling threshold voltage. Egress is throttled after the actuators are retracted and parked when the internal supply voltage falls to or below a second egress throttling threshold voltage.

  • Patent number: 11799893
    Abstract: Computer system security is often implemented using rules-based systems (e.g., allow traffic to this network port, deny it for those network ports; user A is allowed access to these files, but not those files). In enterprises, multiple such systems may be deployed, but fail to be able to intelligently handle anomalies that may technically be permissible but in reality represents a high possibility that there is an underlying threat or problem. The present disclosure describes the ability to build adaptive models using machine learning techniques that integrate data from multiple different domains (e.g. user identity domain, system device domain) and allow for automated decision making and mitigation actions that can provide greater effectiveness than previous systems allowed.

  • Patent number: 11797186
    Abstract: Methods, systems, and devices for latency offset for frame-based communications are described. A memory system may include a host device and a memory device that communicate using frames based on a frame period of a frame clock. The memory device may receive a read command and a write command from the host device, and determine a read latency and a write latency corresponding to the received commands. The memory device may also determine an additional offset latency to add to the write latency to avoid bus contention between read data and write data associated with the read command and the write command, respectively. The offset latency may correspond to an integer quantity of clock periods, which may be less than the frame period.
