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: An asymmetric hollow fiber (CMS) carbon molecular sieve is made by providing a dope solution comprised of a polvimide and a solvent, at a temperature greater than 250° C. that is less than the storage modulus at a temperature of 250° C., but no more than ten times less as measured using dynamic mechanical thermal analysis from 250° C. to a temperature where the polyimide carbonizes. The polvimide is shaped into a hollow polvimide fiber, the solvent removed and the polyimide hollow fiber is heated to pyroiyze the polvimide and form the asymmetric hollow carbon molecular sieve. The asymmetric hollow fiber carbon molecular sieve has a wall that is defined by an inner surface and outer surface of said fiber and the wall has an inner porous support region extending from the inner surface to an outer raicroporous separation region that extends from the inner porous support region to the outer surface.

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.

The method may include analyzing a data store structure to determine whether the data store structure corresponds to a set of criteria, analyzing a query executed against the data store structure to determine performance of the query with respect to the data store structure and providing a proposed data store structure to a customer based at least on part on the analysis of the data store structure and analysis of the query.

Abstract: Methods, apparatus, systems and articles of manufacture to monitor the personal safety of a user of a portable electronic device are disclosed. The safety monitor includes a usage context analyzer to determine a usage context in which the portable electronic device is used based on a history of past usage information. The safety monitor also includes a current usage detector, a threshold alert level monitor, and a safety alert actuator. The current usage detector determines whether the portable electronic device is being used in the usage context at a current time, and, if so, obtains a corresponding threshold alert level that indicates a degree of danger to which a user of the portable electronic device is exposed. The threshold alert level monitor determines whether the threshold alert level has been satisfied, and, if so, the safety alert actuator actuates an output device of the portable electronic device.

Abstract: Interruptible computing resources for executing queries may be selected. When queries are received, the probability that query can complete execution at interruptible computing resources may be determined. Computing resources to process the query may be selected based on the probability. For queries that are performed on computing resources that are interrupted, interruption handling techniques may retry the query on other computing resources or complete the query on other computing resources, in some embodiments.

Abstract: Stateful resource pool management may be implemented for executing jobs. Metrics for pools of computing resources that are configured to execute jobs on behalf of network-based services may be collected. The metrics may be evaluated to detect a modification event for a pool of computing resources. The pool of computing resources may then be modified according to the detected modification event for the pool. Evaluation of metrics may be performed automatically as part of monitoring a resource pool, in some embodiments.

Abstract: Queries may be received and executed by a managed query service. A query directed to data sets that are separately stored in a remote data store may be received. Computing resources to execute the query may be provisioned from a pool of computing resources that are configured to execute queries. The query may be routed to the provisioned computing resources to execute the query. Results may be obtained from the computing resource and provided to a submitter of the query.

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: 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.
