Abstract: Methods, systems, and apparatus, including computer-readable storage media for uncorrectable memory recovery. Different sources of uncorrectable memory error are handled to provide for recovery actions by a host kernel of a machine hosting one or more virtual machines. Rather than defaulting to kernel panic behavior, the host kernel can identify the source of uncorrectable error, and cause the host machine and/or the affected virtual machines to take recovery action that is less disruptive than abrupt shutdown from panic. For example, the host kernel can handle uncorrectable memory error caused by kernel accesses to guest memory of a host virtual machine, as well as uncorrectable memory error improperly raised as a result of known defects in host machine hardware. The host kernel can also be configured to detect sources of overflow in exceptions raised by a processor as a result of uncorrectable memory error.

Abstract: An airbag cushion assembly includes an airbag cushion and an inflation-deflation apparatus that communicates with the airbag cushion. The airbag cushion includes a plurality of sub-airbags, and an airbag gap is formed between adjacent sub-airbags. The inflation-deflation apparatus is provided with an exhaust port, the exhaust port is provided in the airbag gap, and the inflation-deflation apparatus is configured to inflate and deflate the airbag cushion. For the airbag cushion assembly, the exhaust port is provided in the airbag gap, air exhausted by the airbag cushion takes away damp air accumulated between a patient and the airbag cushion, to reduce humidity of the contact area between the patient and the airbag cushion, thereby achieving a pressure sore prevention effect.

Abstract: This disclosure describes techniques for updating planogram data associated with a facility. The planogram may indicate, for different shelves and other inventory locations within the facility, which items are on which shelves. For example, the planogram data may indicate that a particular item is located on a particular shelf. Therefore, when a system identifies that a user has taken an item from that shelf, the system may update a virtual cart of that user to indicate addition of the particular item. In some instances, however, a new item may be stocked on the example shelf instead of a previous item. The techniques described herein may use sensor data generated in the facility to identify this change and update the planogram data to indicate an association between the shelf and the new item.

Abstract: The application discloses a method for preparing chitin highly dispersible in aqueous phase and prepared chitin. After chitin is ground, dissolved, modified with glycidol and purified, a final product glycidol chitin is obtained. The glycidol chitin prepared according to this method has good solubility in purified water, and the concentration can reach 100 mg/mL, which is obviously different from common insoluble or poorly soluble chitin derivatives. Glycidol chitin may have a wide range of application prospects in biomedicine, cosmetics, absorbable materials, and other related aspects.

The method may involve, for each group of computing devices, determining an amount of used storage at the group of computing devices exceeding a predefined first threshold value that is less than the available storage capacity and calculating a storage cost based on the determined amount of used storage exceeding the predefined first threshold value, determining a total storage cost of the plurality of groups of computing devices based on a sum of the calculated storage costs, determining a transfer of one or more projects between the groups of computing devices that reduces the total storage and directing the plurality of groups of computing devices to execute the determined transfer.

Abstract: The aspects of the present disclosure provide a method and an apparatus for implementing hardware resource allocation. For example, the apparatus includes processing circuitry. The processing circuitry obtains a first value that is indicative of an allocable resource quantity of a hardware resource in a computing device. The processing circuitry also receives a second value that is indicative of a requested resource quantity of the hardware resource by a user, and then determines whether the second value is greater than the first value. When the second value is determined to be less than or equal to the first value, the processing circuitry requests the computing device to allocate the hardware resource of the requested resource quantity to the user, and subtracts the second value from the first value to update the allocable resource quantity of the hardware resource in the computing device.

Abstract: The disclosed technology provides techniques, systems, and apparatus for proactively detecting, containing, and recovering from uncorrectable memory errors in distributed computing environment. An aspect of the disclosed technology includes scanning, by a scanner of a host machine, memory of the host machine for errors. After the scanner detects an error, the scanner may generate an error notification. The scanner may transmit the error notification to one or more processors of the host machine to implement mitigation techniques.

Abstract: Described herein are methods and systems for the weight estimation of commercial vehicles and using these estimates to control different vehicle systems such as powertrain, brakes, and suspension. A vehicle comprises a weight estimator, which receives input from different vehicle systems and/or sensors (e.g., suspension, powertrain, speedometer, tire pressure monitoring system) and uses these inputs to determine weight values associated with the vehicle (e.g., total weight, weight distribution per axle, weight distribution per wheel, load distribution). These weight values are then used by the power train, brakes, and/or suspension as additional input for operating these systems besides drivers' input, e.g., provided as pedal positions. For example, different weight values can cause different powertrain outputs for the same accelerator pedal position, e.g., greater output for a heavier vehicle. As such, a driver experiences more uniform vehicle responses for different vehicle loads.
