Example portable electronic devices disclosed herein are to adjust a threshold alert level based on event information obtained for a location associated with the portable electronic device, the threshold alert level to indicate a degree of danger to which a user of the portable electronic device is exposed. Disclosed example portable electronic devices are also to determine that the threshold alert level has been satisfied when at least a threshold number of a set of usage attributes associated with the threshold alert level are detected in a monitored set of usage attributes.

Abstract: Query execution status may be tracked to selectively route queries to resources for execution. The completion of queries executing at computing resources obtained from a pool of computing resources configured to execute queries may be detected. Instead of returning the computing resources to the pool, the computing resources may be identified as available in resource management data. When another query is received, the resource management data may be evaluated to select an available computing resource. The query may then be routed to the selected computing resource for execution.

Abstract: This disclosure describes systems and methods that facilitate the generation of recommendations by traversing a graph. Walks that traverse the graph may be initiated from a plurality of different nodes in the node graph. In order to give greater or lesser weight to particular nodes, the walks may have different lengths depending on the nodes from which they are initiated, or an unequal amount of walks may be distributed between nodes from which walks are initiated. A plurality of walks through a node graph may be tracked, and visit counts or scores for nodes in the node graph may be determined. For example, scores may be increased for nodes that are visited by a walk initiated from a first node and a second walk initiated from a second node, or scores may be decreased for nodes that are not visited by a first walk initiated from a first node and a second walk initiated from a second node. Content corresponding to nodes may be recommended based on the scores or visit counts.

Abstract: An industrial controller that integrates with an external controller for improved control of an industrial machine or process and for coordinating internal motion control functions of the industrial controller with the control routines native to the external controller is disclosed. The industrial controller includes one or more internal motion control instructions, such as a jog, cam, follower, or gearing function. The industrial controller further includes an internal motion planner to generate commands for motor drives connected to the industrial controller to execute the internal motion control instructions or user provided motion control instructions in a control program. External vendors have also developed motion planners to generate motion commands, for example, for the axes on robotic equipment.

Abstract: A method of making a hollow fiber carbon molecular sieve is comprised of heating a hollow polymer fiber to a carbonization temperature in an atmosphere that is non-oxidizing to form a hollow fiber carbon molecular sieve, wherein during at least a portion of the heating a tensile force is applied to the hollow polymer fiber. The method may improve the separation of gases similar in size such a propylene from propane.

Abstract: This disclosure describes systems and methods that facilitate generating recommendations by traversing a node graph. For example, recommendations may be generated for a node in the node graph by running a plurality of walks through the node graph and tracking the nodes visited by the walks. For example, a visit count or score may be maintained and/or updated for each node as the walks traverse through the node graph. The walks may be terminated after a defined amount of nodes in the node graph have visit counts or scores that satisfy a criterion. Content corresponding to nodes with the highest visit counts or scores may be recommended.

Abstract: The configuration of computing resources for executing queries may be selected. A comparison of the configuration of computing resources that executed previous queries may be made to select the configuration of computing resources for a received query. A historical query execution model maybe applied, in some embodiments, to determine a resource configuration for computing resources to execute a query. The computing resources may be selected from available computing resources according to the determined resource configuration.

Abstract: One embodiment relates to a handheld surgical instrument that comprises a rotary surgical end effector and a coupler configured to cause rotation of the same. The handheld surgical instrument further comprises a motor, which is configured to drive a motor output region. The handheld surgical instrument further comprises a transmission, which defines a transmission input region that interfaces with the motor output region and a transmission output region coupled to the transmission input region. The transmission output region is operably coupled to the coupler, and the transmission is configured to alter the speed of the coupler relative to the motor output region. The motor output region and the transmission input region interface one another at a motor-transmission interface, and the motor-transmission interface comprises a motor-transmission backlash such that drive of the motor output region within the motor-transmission backlash does not cause rotation of the rotary surgical end effector.

Abstract: A digital-to-analog converter system has digital-to-analog converters, a common output, and a digital controller for transmitting first codes to one of the converters at a radio-frequency digital rate, and for transmitting second codes to another one of the converters at the same rate. The digital controller includes a timing system for operating each converter at the digital rate in a return-to-zero configuration, such that a signal from the first converter is transmitted to the common output while the second converter is reset, and vice versa. The digital-to-analog converter system can generate a radio-frequency analog signal having signals in first and second Nyquist zones simultaneously.

Abstract: Disclosed are approaches for using overlapping geo-fences to confirm delivery of a shipment. A first client computing device and a second client computing device may be in data communication with a server computing device. The server computing device may receive a delivery notification from the first client computing device. The server computing device may receive a first position of the first client computing device and a second position of the second client computing device. The server computing device may then determine that the second position is within a threshold distance of the first position or vice versa. Finally, the server computing device may generate a delivery confirmation in response to a first determination that the second position is within a threshold distance of the first position and a second determination that the first position is within a threshold distance of the second position.
