Abstract: A file is received from a client for storage at a deduplication file system. The file is in an archive file format that is used by an application on the client. The file includes subfiles compressed together in the file according to the archive file format, local headers corresponding to the subfiles, and a central directory used by the application to locate information stored in the file. The file is decompressed to store the subfiles separately. A metadata file is created that describes a structure of the file. The metadata file includes the local headers, central directory, pointers to the subfiles, but does not include the subfiles. The file is presented to the client as a single file having the archive file format. A request from the client is received to read the file and the metadata file is read to return data responsive to the request.

Abstract: Methods and systems are provided for regenerating a particulate filter positioned in an exhaust system of an engine of a vehicle. In one example, a method comprises obtaining a first air flow in an intake of the engine and obtaining a second air flow in the intake of the engine, where regeneration of the particulate filter is conducted in response to the first air flow differing from the second air flow by at least a threshold amount, where the first air flow and the second air flow comprise air flow routed from the exhaust system to the intake of the engine. In this way, the particulate filter may be regenerated under conditions where a loading state of the particulate filter is not known.

Abstract: In a Non-Orthogonal Multiple Access (NOMA) system, a user equipment (UE) can be configured to transmit signals with multiple access (MA) signatures. If a base station configures multiple MA signatures to a UE, the UE can select one or more MA signatures, then transmit signals in parallel, serial, or in hybrid ways. Due to the flexibility and complexity of the UE selecting MA signatures without an explicit configuration from the base station, additional control overhead is provided to support parallel HARQ processing. In addition, a new DCI format is disclosed that supports multi-branch NOMA transmission, which allows multiple ACK/NACKs within a DCI. Further, using the techniques disclosed herein, a base station can explicitly indicate ACK-NACKs without being assisted by a HARQ ID field.

Abstract: A harvesting combine has a forward power processing unit (PPU) powered by an internal combustion engine, a rear grain cart for storage of harvested grain, a forward operator cab, a cleaning fan assembly located about the forward bottom of the PPU, and rotor and concaves assembly for threshing grain. The harvesting combine is improved by locating a charge fan assembly behind the forward operator cab and drawing air from about the top of the PPU and directing a portion of an air flow from the charge fan assembly downwardly into the cleaning fan assembly.

Abstract: The disclosure is directed to a vehicle cargo bed capacitive sensor system programmed to determine when items in the cargo bed (e.g., the bed of a pickup truck) are being manipulated. The system may include one or more capacitive sensors disposed on one or more cargo bed walls. The system detects items exiting the cargo bed (e.g., by falling out of the cargo bed), and detects shifting cargo. The system may also detect a person reaching into the cargo bed, and can provide information such as the location where the cargo was taken or lost from the cargo bed, and live feed images of the intruding party. The system may automatically extend and contract the capacitive field to control sensor sensitivity, and adjust the sample rate of the sensor data based on characteristics of vehicle operation, such as drive mode, speed, GPS direction, and other factors.

Abstract: An autonomous vehicle detects a tailgating vehicle and uses various response mechanisms. A vehicle is identified as a tailgater based on whether its characteristics meet a variable threshold. When the autonomous vehicle is traveling at slower speeds, the threshold is defined in distance. When the autonomous vehicle is traveling at faster speeds, the threshold is defined in time. The autonomous vehicle responds to the tailgater by modifying its driving behavior. In one example, the autonomous vehicle adjusts a headway buffer (defined in time) from another vehicle in front of the autonomous vehicle. In this regard, if the tailgater is T seconds too close to the autonomous vehicle, the autonomous vehicle increases the headway buffer to the vehicle in front of it by some amount relative to T.

Abstract: Techniques are described herein that are capable of performing intent-based scheduling via a digital personal assistant. For instance, an intent of user(s) to perform an action (a.k.a. activity) may be used to schedule time (e.g., on a calendar of at least one of the user(s)) in which the action is to be performed. Examples of performing an action include but are not limited to having a meeting, working on a project, participating in a social event, exercising, and reading.

Abstract: This specification describes computer-implemented methods and systems. One method includes receiving, by a neural network of a speech recognition system, first data representing a first raw audio signal and second data representing a second raw audio signal. The first raw audio signal and the second raw audio signal describe audio occurring at a same period of time. The method further includes generating, by a spatial filtering layer of the neural network, a spatial filtered output using the first data and the second data, and generating, by a spectral filtering layer of the neural network, a spectral filtered output using the spatial filtered output. Generating the spectral filtered output comprises processing frequency-domain data representing the spatial filtered output. The method still further includes processing, by one or more additional layers of the neural network, the spectral filtered output to predict sub-word units encoded in both the first raw audio signal and the second raw audio signal.

Abstract: Various embodiments can implement a multi-system or node architecture that can be deployed on-demand and augment existing systems with pre-configured nodes that can be installed within existing architecture. The multi-node architecture is flexible for integration into many systems and can also stand alone to provide data validation and assurance. Various embodiments of the multi-node architecture enable private and public distributed ledgers (e.g., blockchains) that enhance security, enhance confidentiality, and eliminate the need to trust the provider/hosts of the data validation information and/or the hosts of the confidential information.
