Abstract: Techniques are described for automatically generating job descriptions. Job categories are identified for the documents in the job description dataset based on clustering the documents. Sections within each document in the job description dataset are automatically identified, and each identified section is automatically classified. Each type of section is analyzed independently of the other section types using natural language processing, which allows automatic generation of each section of a new job description based on the section-specific data derived from the dataset. Section- and category-specific selective phrases are identified within the job description dataset, and embeddings are generated for the identified selective phrases. A request to generate a new job description for a particular category is received.

Abstract: A camera with a field of view of a shelf may acquire images of items on the shelf at subsequent times. An analysis of each image yields a set of estimated locations of the items on the shelf. Based on a working volume of the shelf, a subset of valid estimated locations of the items at the shelf may be determined. Thereafter, a count of the items on the shelf at a particular time may be determined using the subset of valid estimated item locations. By comparing the count of items at the shelf at two subsequent times, a change in quantity of the items on the shelf may be determined. Interaction data may be generated in response to detecting the change in quantity of items at the shelf.

Abstract: A data storage device configured to access a magnetic tape is disclosed, wherein the data storage device comprises at least one head configured to access the magnetic tape, wherein the head comprises a write element, a first read element substantially aligned with the write element, and a second read element laterally offset from the first read element. Data is written to a data track and read-after-write verify is performed using the write element and the first read element. In response to a read command received from a host, the data track is read using the second read element to compensate for a stretching of the magnetic tape.

Abstract: A host computer system may be configured to connect to a network. The host computer system may be configured to implement a workspace and an isolated computing environment. The host computer system may be configured to isolate the isolated computing environment from the workspace using an internal isolation firewall. The internal isolation firewall may be configured to prevent data from being communicated between the isolated computing environment and the workspace, for example, without an explicit user input. When malware is received by the isolated computing environment, the internal isolation firewall may be configured to prevent the malware from accessing data on the workspace of the host computer system. The host computer system may be configured to implement one or more mechanisms that prevent malware received by the host computer system from exfiltrating, to a network destination, data from the host computer system and data from other devices on the network.

Abstract: A bi-directional direct current (DC) solid state power controller (SSPC) architecture and control method. The SSPC protects a DC distribution system by isolating both the positive and negative buses independently in case of short circuit or ground fault. The SSPC architecture includes two self-heal interleaved capacitors and includes a fast, soft-charging control technique that provides line-isolated charging of the DC bulk capacitor to avoid inrush current when powering up the DC distribution system. The soft-charging function alternately charges one of the two interleaved capacitors, while the other capacitor discharges to the DC bulk capacitor. Repetitive switching results in a charging and discharging process that increases the voltage of the DC bulk capacitor prior to powering up the DC distribution system, while keeping the DC power source isolated from the load.

Abstract: A robot has a component that is oriented relative to a chassis of the robot. For example, a display screen is mounted to the robot using a pan and tilt arrangement. During operation, trajectory data indicative of a trajectory is determined that specifies where the robot is intended to travel as it moves through an environment. This trajectory data is used to dynamically orient the component. For example, as the robot moves through the environment, the display screen would be oriented such that it appears to be “facing” a point in space that is associated with a point on the trajectory.

Abstract: Devices and techniques are generally described for fraud detection. In various examples, a first plurality of requests are received over a first time period. In at least some examples, the first plurality of requests may be requests to access a first service. A hierarchical data representation comprising an ordered set of values may be determined for each request of the first plurality of requests. A first subset of the first plurality of requests may be determined. The hierarchical data representation associated with each request of the first subset may include fewer than a threshold number of value substitutions relative to each other hierarchical data representation of the first subset of the first plurality of requests. Access to the first service may be prevented by subsequent requests associated with the first subset of the first plurality of requests.

Abstract: Systems, methods, and computer-readable media are disclosed for optimizing network performance on a computer device to improve quality of experience by determining which network settings on the computing device to adjust. A clustering algorithm may identify various classes of networks and a classification algorithm may determine a network class specific to a network on a computing device. The effects of certain network settings for that networks class may be determined and the network setting and/or settings that optimizes the network performance may be promoted. The system may periodically analyze network data to recalculate the appropriate networks class and may determine different network settings based on the recalculation, facilitating mid-session improvements to the quality of experience.

Abstract: The present disclosure generally relates to scheduling zone-append commands for a zoned namespace (ZNS). Rather than taking zone-append commands in order or randomly, the zone-append commands can be scheduled in the most efficient manner consistent with the open zones of the ZNS. A zone priority is determined based upon the length of time that a zone has been open together with the zone status. Generally, the older the zone and/or the more full that a zone is increases the priority. Once the zone priority is established, the zone-append commands are scheduled to ensure the zone-append commands for the high priority zones are processed first so that the open zone can be filled prior to closing.

Abstract: Various aspects include methods of compensating for issues caused by charge sharing between pixels in pixel radiation detectors. Various aspects may include measuring radiation energy spectra with circuitry capable of registering detection events occurring simultaneous or coincident in two or more pixels, adjusting energy measurements of simultaneous-multi-pixel detection events by a charge sharing correction factor, and determining a corrected energy spectrum by adding the adjusted energy measurements of simultaneous-multi-pixel detection events to energy spectra of detection events occurring in single pixels. Adjusting energy measurements of simultaneous-multi-pixel detection events may include multiplying measured energies of simultaneous-multi-pixel detection events by a factor of one plus the charge sharing correction factor.
