| 20090294257 | Impact Bed Assembly for Conveyor Belts - Impact bed assemblies are provided, both static and dynamic, for absorbing impact forces taken by conveyor belts. The static and dynamic bed assemblies generally are constructed to optimize their impact absorption capacities while minimizing their space requirements under the belt. | 12-03-2009 |
| 20100000842 | Removable Cartridge Cleaner - A removable cartridge cleaner assembly is provided that allows for faster and easier removal of the belt cleaner blades out from under a conveyor belt. In one aspect the assembly includes a biasing surface of one of an elongate support assembly and a channel member configured to be engaged by a securing member and urge distal ends of legs of the channel member into tight engagement with the elongate support assembly and minimize debris accumulation therebetween. In another aspect, the elongate base member and rail member each include lateral portions configured to slidably engage corresponding wedge portions to urge the rail member toward the base member. A method of installing a belt cleaner assembly is also provided which includes camming a rail member downwardly toward the support member upper surface. | 01-07-2010 |
| 20110203904 | REMOVABLE CARTRIDGE CLEANER - A removable cartridge cleaner assembly is provided that has an insertion device for ease in installing an elongate cartridge assembly carrying belt cleaner assemblies onto an elongate support extending across a conveyor belt in an operative position thereon. In one form, an elongate lever handle pivotally connected to the elongate cartridge assembly can be used to generate a leveraged insertion force, preferably by an operator that does not need to reach into the operating envelope of the conveyor system, e.g, beyond tensioning mechanisms or under the belt. The handle and the cartridge assembly can have an over center locking mechanism therebetween for providing the operator tactile feedback as to when pivoting of the lever handle has caused the cartridge assembly to be shifted to its operative position on the support. | 08-25-2011 |
| 20110247915 | REMOVABLE CARTRIDGE CLEANER - A removable cartridge cleaner assembly is provided that allows for faster and easier removal of the belt cleaner blades out from under a conveyor belt. In one aspect the assembly includes a biasing surface of one of an elongate support assembly and a channel member configured to be engaged by a securing member and urge distal ends of legs of the channel member into tight engagement with the elongate support assembly and minimize debris accumulation therebetween. In another aspect, the elongate base member and rail member each include lateral portions configured to slidably engage corresponding wedge portions to urge the rail member toward the base member. A method of installing a belt cleaner assembly is also provided which includes camming a rail member downwardly toward the support member upper surface. | 10-13-2011 |

| 20080307441 | System and Method for Call Stack Sampling Combined with Node and Instruction Tracing - A system and method for Java™ call stack sampling combined with native sampling is presented. A kernel-mode device driver records and stores sampled context information that includes a program counter, a thread identifier, and a process identifier. The sampling thread receives a notification from the kernel-mode device driver, and proceeds to collect call stack information from a Java™ Virtual Machine. In turn, the sampling thread retrieves the sampled context information and harvests symbols corresponding to a loaded module. Once symbols are harvested, the sampling thread combines returned call stack nodes with native function leaf nodes into a unified output tree that provides the relationship between the two different node types. In one embodiment, the sampling thread may generate native function leaf nodes and the unified output tree in a post-processing manner. | 12-11-2008 |
| 20090044198 | Method and Apparatus for Call Stack Sampling in a Data Processing System - A computer implemented method, apparatus, and computer usable program code for sampling call stack information. An event is monitored during execution of a plurality of threads executed by a plurality of processors. In response to an occurrence of the event, a thread is identified in the plurality of threads to form an identified thread. A plurality of sampling threads is woken, wherein a sampling thread within the plurality of sampling threads is associated with each processor in the plurality of processors and wherein one sampling thread in the plurality of sampling threads obtains call stack information for the identified thread. | 02-12-2009 |
| 20090083002 | Method and Apparatus for Analyzing Idle States in a Data Processing System - A computer implemented method, apparatus, and computer usable program code to collect information for a system or processor having a transition between an idle state and a non-idle state to form collected system or processor information. The collected system or processor information is provided for analysis by an application. | 03-26-2009 |
| 20100017583 | Call Stack Sampling for a Multi-Processor System - A computer implemented method, apparatus, and computer usable program code for sampling call stack information. Responsive to identifying an interrupt, a determination is made as to whether all processors in a plurality of processors have generated the interrupt. A determination is made as whether to sample the call stack information based on a policy in response to a determination that all of the processors have generated the interrupt. The call stack information is sampled if a determination is made to sample the call stack information based on the policy | 01-21-2010 |
| 20100333071 | Time Based Context Sampling of Trace Data with Support for Multiple Virtual Machines - Mechanisms for time based context sampling of trace data with support for multiple virtual machines are provided. In response to the occurrence of an event, a plurality of sampling threads associated with a plurality of executing threads executing on processors of a data processing system are awakened. For each sampling thread, an execution state of a corresponding executing thread is determined with regard to one or more virtual machines of interest. For each sampling thread, based on the execution state of the corresponding executing thread, a determination is made whether to retrieve trace information from a virtual machine of interest associated with the corresponding executing thread. For each sampling thread, in response to a determination that trace information is to be retrieved from a virtual machine of interest associated with the corresponding executing thread, the trace information is retrieved from the virtual machine. | 12-30-2010 |
| 20110289361 | IDLE TRANSITIONS SAMPLING WITH EXECUTION CONTEXT - A process generates a sample based on an event. The process identifies, with a dispatch monitor, a next dispatched monitored thread that is dispatched by a current processor. The process sets a processor affinity of the next dispatched monitored thread such that the next dispatched monitored thread runs only on the current processor without being able to migrate to a different processor. The process also retrieves, with a sampled thread that runs on the current processor, a next dispatched monitored thread call stack after the processor affinity of the next dispatched monitored thread has been set to the processor. The process restores the processor affinity of the next dispatched monitored thread after the next dispatched monitored thread call stack has been obtained. | 11-24-2011 |
| 20110307640 | CALL STACK SAMPLING WITH LIGHTWEIGHT THREAD MIGRATION PREVENTION - A sample is generated based on an event. Further, an interrupt handler captures information for an interrupted thread on a current processor. In addition, an affinity of the interrupted thread is set such that the interrupted thread runs only on the current processor without being able to migrate to a different processor. A sampler thread that runs on the current processor retrieves a call stack associated with the interrupted thread after the affinity of the interrupted thread has been set to the current processor. The affinity of the interrupted thread is restored after the call stack has been retrieved. | 12-15-2011 |
