  • Patent number: 12248363
    Abstract: A storage device non-fatal error debug system includes a storage device including a storage device chassis, storage device subsystems housed in the storage device chassis, and a non-fatal error debug subsystem provided in the storage device chassis and coupled to each of the storage device subsystems. The non-fatal error debug subsystem provides a counter system for each of a plurality of data path stages performed by the storage device subsystems to provide data path(s) in the storage device, and monitors each counter system during the execution of commands by the storage device subsystems via the performance of the data path stages. When the non-fatal error debug subsystem determines that a counter system provided for a data path stage performed by a storage device subsystem to provide a data path in the storage device indicates a non-fatal error, it collects debug information associated with that data path stage.

  • Publication number: 20240225337
    Abstract: A retrofittable curtain apparatus capable of being installed onto existing curtain tracks comprising a curtain and curtain carriers. The apparatus may comprise a pair of latches on either side to facilitate simple installation onto the curtain track by clamping the apparatus to the track. A pair of switches located on either side of the apparatus allows a user to activate the apparatus by tugging on the curtain, pulling it taut over the switch thereby actuating it. The apparatus comprises an internal assembly of efficiently arranged gears and motors that produce a substantially small horizontal form factor, allowing for use with wave fold curtains.

  • Patent number: 11836073
    Abstract: A counter system includes a counter management subsystem, a storage subsystem having storage elements, and a non-volatile memory system storing a first counter including a first value field/first bitmap field combination for each storage element, and a second counter including a second value field/second bitmap field combination for each storage element. The counter management subsystem resets the first counter and, following each storage operation on a storage element, updates a bit in the first bitmap field for that storage element. When one of the first bitmap fields is filled, the counter management subsystem converts each first value field/first bitmap field combination to a respective first value, resets the second counter, updates the second value field for each storage element with the respective first value for each storage element and, following each storage operation on a storage element, updates a bit in the second bitmap field for that storage element.

  • Patent number: 9981190
    Abstract: Techniques are described for performing telemetry based interactive content generation for online services. For example, telemetry data can be obtained from individual users of the online service and/or from multiple users of the online service (e.g., and processed to generate aggregate telemetry data). Other types of data can also be obtained, including service management data. Service management data can be generated from the users of the online service and can comprise user density information for virtual areas of the online service. Using telemetry data (e.g., user-specific telemetry data and/or aggregate telemetry data), service management data, and/or other types of data related to the online service, new interactive experiences can by dynamically created for the users of the online service.
