Abstract: A design structure for a circuit for switching clock signals with logic devices using a glitchless clock multiplexer optimized for synchronous and asynchronous clocks. The design structure comprises a circuit having an asynchronous clock group and one or more synchronous clock group(s). The asynchronous group comprises a plurality of high frequency glitchless control (HFGC) blocks for asynchronous clock sources. Each synchronous group comprises a plurality of HFGC blocks for synchronous clock sources. The circuit comprises a multiplexer for receiving delayed input clock signals from HFGC blocks for asynchronous clock sources and from HFGC blocks for synchronous clock sources. A switching latency (period in which no clock pulse appears at the final output of the circuit) from a first input clock signal belonging to a synchronous group to a second input clock signal belonging to the same synchronous group is one clock cycle or less of the second input clock signal.

Abstract: A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.

The computer identifies a set of aspects within the production rules responsive to a determination that the common sub-sequences exist. Finally, the computer modifies the unified modeling language artifacts.

Abstract: A user evaluation of distributed content comprising an Evaluation Program (EP) that creates a user session when a user accesses distributed content is stored. The user evaluation is saved with other information such as the time and date of the evaluation, the user's personal information, and the navigation path the user used to access the distributed content page. The EP records the user's navigation of the distributed content in the user session. The EP gives the user the opportunity to rate distributed content. The EP saves the user's evaluation with the user session data and external stimuli data. The EP closes the user session when the user leaves the distributed content. The EP reopens the user session when the user returns to the distributed content.

Abstract: A method, an apparatus, a system, and a computer program product are presented for determining whether a file system resource is a file system resource that is contained within a file system that can be automounted by a data processing system. A target file system resource is identified, after which a first file system data structure that represents a file system that contains the target file system resource is identified using a file system resource data structure that represents the target file system resource. If it is determined that the first file system data structure identifies a file system resource data structure that represents an automount point, the target file system resource is marked as an automount file system resource. File system resource data structures that represent hierarchically more inclusive file system resources are traversed if necessary to search for an automount point.

The chat application may automatically set the user's current chat status at a given time based on telephone line activity only if the caller ID information associated with the incoming telephone call matches a priority telephone number.

Abstract: A method, computer program product, and apparatus for monitoring patterns of motion are provided. A signal is received from a sensor on a user, wherein movement of the user causes the sensor to generate power to emit a signal indicative of the movement of the user. The signal is analyzed to form a current pattern of motion. The current pattern of motion is compared to a baseline pattern of motion associated with the user. A difference between the current pattern of motion and the baseline pattern of motion associated with the user is determined to form a difference. The difference is compared to a predetermined threshold. Responsive to the difference exceeding the predetermined threshold, an alert is sent.

An inverter inverts a direct voltage signal to an alternating current signal with a desired frequency in the power generation path. A transformer increases a voltage level of the alternating current signal to a desired voltage level.

Abstract: Performing local peer volume polling by a mobile device is provided. In response to determining that a polling function is enabled in a mobile device, a request is transmitted to each of the peer mobile devices using the polling function. The polling function requests audible operation level setting data from peer mobile devices within a predetermined distance of the mobile device. A map is computed of the peer mobile devices, along with their associated audible operation level settings, based on responses to the request for the audible operation level setting data. The map and audible operation level settings for the peer mobile devices are analyzed using rules to detect an inappropriate volume setting for the mobile device. In response to determining that a current audible operation level setting for the mobile device is inappropriate using the rules, a new audible operation level setting is applied to the mobile device.
