  • Patent number: 12374529
    Abstract: This disclosure relates to systems and apparatuses for the cleaning of HDP chambers, and more specifically, for remote plasma source (“RPS”) systems used for the generation and delivery of cleaning radicals to the interior of such chambers for the purposes of reacting with and removing materials deposited therein during the chambers' normal operation, wherein the plasma source and the power supply of the RPS system are decoupled from one another, the form factor of the plasma source is such that it may be mounted in immediate proximity to the target chamber, and wherein the plasma source uses variable capacitors in order to tune the RF signals it generates to the impedance of the conductive coil, such as may be due to changes in gas pressures inside of the system, so that the RF load in the coil may be balanced in near-real time.

  • Patent number: 12351654
    Abstract: High concentrations of recycle polymer are gasified in a partial oxidation gasifier to make a syngas useful to make a variety of chemicals and polymers, such as cellulose ester. Polymers such as cellulose esters can be made that are obtained from sustainable sources, recycle sources, and are biodegradable. Circularity in the manufacture of textiles and/or plastics made from the fibers of such cellulose esters can now be achieved. The process of making such a syngas from high concentrations of recycle polymer (e.g. textiles and/or plastics) includes campaigning for the production of syngas.

  • Patent number: 12338211
    Abstract: A recycle content ethylene is fed to a reactor to make propionaldehyde having recycle content. The recycle ethylene feedstock is derived directly or indirectly from the cracking of recycle content pyrolysis oil. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.

  • Patent number: 12292806
    Abstract: A method, computer program product, and computer system are provided for testing drives in a redundant array of independent disks (RAID) array. The method includes: mirroring data from a selected drive to be tested in a RAID array to spare storage space in the RAID array; and, once the data is successfully mirrored, testing the selected drive to identify a preemptive failure of the selected drive. The RAID may be a traditional RAID (TRAID) array and the spare space may be a spare physical drive independent of array drive members. The RAID array may alternatively be a distributed RAID (DRAID) array and the spare space may be spare capacity spread through the array drive members.

  • Patent number: 12270212
    Abstract: An Enhanced Lift Assist Device is described. The device allows a user to lift and manipulate large, heavy or bulky items by applying force to the item as opposed to traditional control methods such as buttons. This force based system provides ease of movement of the item, making it appear much lighter than it actually is. The Enhanced Lift Assist Device also includes an adjustable base that allows for change of orientation of the device that may include leveling or self-leveling functionality, allowing the device to be operated in non-traditional environments that require leveling or operational adjustments for proper functioning.

  • Patent number: 12210604
    Abstract: Systems and methods for multi-modal user device authentication are disclosed. An example electronic device includes a first sensor, a microphone, a first camera, and a confidence analyzer to authenticate a subject as the authorized user in response to a user presence detection analyzer detecting a presence of the subject and one or more of (a) an audio data analyzer detecting a voice of an authorized user or (b) an image data analyzer detecting a feature of the authorized user. The example electronic device includes a processor to cause the electronic device to move from a first power state to a second power state in response to the confidence analyzer authenticating the user as the authorized user. The electronic device is to consume a greater amount of power in the second power state than the first power state.

  • Publication number: 20240239920
    Abstract: Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.
