| 20090091853 | APPARATUS, SYSTEM, AND METHOD FOR INTERCHANGE TESTING - An apparatus, system, and method are disclosed for interchanging testing. A test module moves a first tape from a tape pool to a first reserved slot of plurality of reserved slots using an accessor. In an embodiment, there is one (1) reserved slot corresponding to each of a plurality of tape drives. Each reserved slot is configured to store one tape for the corresponding tape drive. No other tape drive accesses the stored tape from the reserved slot. Additionally, the test module loads the first tape to a first tape drive from the first reserved slot using the accessor, reads to end of at least two file marks on the first tape using the first tape drive, rewinds to a beginning of the first tape using the first tape drive, spaces forward on the first tape to a beginning of a second of the at least two file marks using the first tape drive, writes specified data to the first tape using the first tape drive, writes a new second file mark to the first tape using the first tape drive, and moves the first tape to the first reserved slot using the accessor. | 04-09-2009 |
| 20090094483 | METHOD OF MAINTAINING TASK SEQUENCE WITHIN A TASK DOMAIN ACROSS ERROR RECOVERY - Tracks of data or other data units are copied from a primary storage system to a secondary storage system. For multiple-track or multiple-data unit transfers, a group of tracks or data units which are sequentially related are transferred. A respective task is defined at the primary storage system for monitoring a progress of the transfer of each of the respective data units in a group. A state is maintained for monitoring a progress of the transfer of the group responsive to the progress of each of the tasks. A normal state is selected when there are no failed tasks. A recovery state is selected when there is a failure, and the status of the remaining tasks is being ascertained. A retry state is selected following the recovery state to retry the failed tasks. A failed state indicates an unrecoverable failure. | 04-09-2009 |
| 20090150897 | MANAGING OPERATION REQUESTS USING DIFFERENT RESOURCES - Provided are a system and program for managing operation requests using different resources. In one embodiment, a first queue is provided for operations which utilize a first resource of a first and second resource. A second queue is provided for operations which utilize the second resource. An operation is queued on the first queue until the first resource is acquired. The first resource is released if the second resource is not also acquired. The operation is queued on the second queue when the first resource is acquired but the second resource is not. In addition, the first resource is released until the operation acquires both the first resource and the second resource. | 06-11-2009 |

| 20080239948 | SPECULATIVE CONGESTION CONTROL SYSTEM AND CROSS-LAYER ARCHITECTURE FOR USE IN LOSSY COMPUTER NETWORKS - Methods and apparatus are provided to improve data throughput in a wireless, wireline or a combination wireless and wireline communication system. A congestion control manager selects between an assumption based congestion control algorithm and a speculation based congestion control algorithm. The selected algorithm generates data recovery instructions including instructions for resizing, or not, congestion window sizing for the communication gateways. By making the selection between the assumption based congestion control algorithm and the speculation based congestion control algorithm based upon network information, data recovery and throughput is optimized for networks having lossy data links. | 10-02-2008 |
| 20080239953 | METHOD AND APPARATUS FOR MINIMIZING CONGESTION IN GATEWAYS - Methods and apparatus are provided to reduce data congestion and thus improve data throughput in gateways used in a wireless, wireline or a combination wireless and wireline communication system. The congestion management system optimally resizes, or not, congestion window (or buffer) sizing and threshold for the communication gateways based upon mathematical models. Application of the inventive congestion management method optimizes data recovery and throughput in communication networks, particularly those networks having lossy data links. | 10-02-2008 |
| 20090078847 | DISTRIBUTED NETWORK VIBRATION ISOLATION SYSTEM AND VIBRATION ISOLATORS USEFUL THEREIN - A distributed network vibration isolation system includes several vibration isolation nodes distributed throughout a structure. The nodes wirelessly intercommunicate and include a passive structural isolation device and an active structural isolation device. The nodes work together via wireless communication to isolate a payload from a disturbance source. | 03-26-2009 |
| 20090154528 | ADAPTIVE MULTI-CHANNEL INTEGRATED WIRELESS NETWORK SYSTEM ARCHITECTURE - An adaptive multi-channel architecture for a wireless network is provided. A frequency hopping sequence generator module is compliant with a frequency hopping spread spectrum (FHSS) communications protocol. The frequency hopping sequence generator module is capable of performing FHSS concurrently on a plurality of communications channels. A frequency replacement module is coupled to the frequency hopping sequence generator module. The frequency replacement module is configured to receive feedback data over a feedback channel and adaptively select a transmission channel from the plurality of communications channels using the feedback data. | 06-18-2009 |

| 20110274021 | DETECTING A WLAN SIGNAL USING A BLUETOOTH RECEIVER DURING BLUETOOTH SCAN ACTIVITY - A BT receiver RF front end receives RF energy in a sequence of BT scan windows. Throughout a scan window, the front end is tuned to one hop frequency. Before and after the window the front end is in a disabled state. A WLAN energy detector processes an output of the front end during the window and determines whether more than a predetermined amount of RF energy was received onto the front end during the window. A BT baseband processor attempts to demodulate the output of the front end. If the WLAN energy detector determines that the predetermined amount of RF energy was received and if a BT signal could not be demodulated, then a WLAN wake-up signal is asserted, thereby causing a WLAN transceiver to be powered up to receive WLAN signals. BT scan intervals are varied in duration to facilitate a BT scan window overlapping a WLAN beacon. | 11-10-2011 |
