  • Patent number: 11675616
    Abstract: Methods and apparatuses for scheduling tasks with a job scheduler are disclosed. In one embodiment, the method comprises: tracking a number of active tasks for each key of a plurality of keys; writing, by a scheduler, a query to identify a next scheduled task among a plurality of scheduled tasks ordered by time in a task queue, the query having an index that excludes tasks associated with a list of one or more keys of the plurality of keys that have a count of active tasks greater than a first limit associated with each key; querying, by a scheduler, the task queue using the query to identify the next scheduled task among the plurality of scheduled tasks, the next scheduled task being associated with a key not excluded by the query; and executing the next scheduled task.

  • Patent number: 11327843
    Abstract: Provided are an apparatus and method for managing data storage. A first log structured array stores data in a storage device. A second log structured array in the storage device stores metadata for the data in the first log structured array, wherein the second log structured array storing the metadata for the first log structured data storage system is nested within the first log structured array, and wherein the first and second log structured arrays comprise separate instances of log structured arrays. Address space is allocated in the second log structured array for metadata when the allocation of address space is required for metadata for data stored in the first log structured array.

  • Patent number: 11181591
    Abstract: A sensor device is provided for use in tire inspection. The sensor device is configured for removable placement along the inner surface of the tire. The sensor device includes multiple rows of sensors, which are used to provide signals that can compensate for the effect of vibrations or mechanical agitation as the sensors are passed over the inner surface of the tire. The sensor device may have a profile that allows for placement of the multiple rows of sensors in close proximity to the inner surface of the tire.

  • Patent number: 11175262
    Abstract: The present disclosure describes methods of inspecting polymeric material that includes one or more elongated ferrous reinforcements. The method includes applying a magnetic field to any one or more reinforcements. The method further includes positioning an array of magnetic flux sensors near the one or more reinforcements, and detecting the presence of magnetic flux leakage along any of the one or more reinforcements. It is then determined whether the magnetic flux leakage occurs at a damaged location along the one or more reinforcements or at a reinforcement joint.

  • Publication number: 20200332250
    Abstract: Compositions and methods are described for preparing media, feeds, and supplements. Such methods and medias may display increased stability of labile components and may use, for example, microsuspension and/or encapsulation technologies, chelation, and optionally, coating and/or mixing the labile compounds with anti-oxidants. The compositions may withstand thermal and/or irradiation treatment and have reduced virus number. These techniques may result in product with extended shelf-life, extended release of their internal components into culture, or in product that can be added aseptically into a bioreactor using minimal volumes. The compositions and methods may optimize the bioproduction workflow and increase efficiency.

  • Patent number: 10603858
    Abstract: A method of detecting tire mold (10) bladder (14) leakage is provided that includes placing an uncured tire (12) into a mold (10), and inflating a bladder (14), that has a fluid (22), within the mold. Sufficient heat and pressure are applied to at least partially cure the tire when the uncured tire is in the mold (10). The mold (10) is opened and electronic smelling is conducted on the at least partially cured tire (12). The electronic smelling is performed in order to determine whether the bladder (14) is leaking the fluid (22).

  • Patent number: 10556393
    Abstract: A method of manufacturing a tire is provided that includes curing the tire (10) in a curing press (12) and applying microwave energy at a given frequency band into the tire. The interaction between the microwave energy and the tire is monitored to obtain a complex reflection coefficient. A root-mean-squared error is calculated using the measured complex reflection coefficient and a reference reflection coefficient. The reference reflection coefficient is from a fully cured tire made from the same material as the tire. Continuous monitoring of the interaction takes place to obtain the complex reflection coefficient along with continuous calculation of the root-mean-squared error at different times during the curing of the tire in the curing press. The calculated root-mean-squared errors are used to determine whether to stop the curing of the tire in the curing press.

  • Patent number: 10533929
    Abstract: A method of using a sensor device for tire inspection is provided. Signals are received from multiples rows of sensors separated by a predetermined distance. The sensors are positioned next to the inner surface of the tire for inspection. Signals from the different rows of sensors are used to identify e.g., breaks in the reinforcements of the tire and also used to identify undesirable signals generated from vibration or jarring of the sensor device.
