  • Block error ratio measurements
    Patent number: 6959406
    Abstract: Block error rate (BLER) measurements are made on a mobile telephone handset without imposing an undesirable processing burden on the handset. An information block flow is maintained by sending repeated message blocks from a test set which are defined at a selected layer in the protocol stack below the topmost layer. Ack/nack messages sent by the handset in response to the message blocks are monitored to determine whether the message blocks have been correctly transported, and thus derive the BLER. The message blocks sent by the test set can either be empty GMM_INFORMATION messages, or LLC frames with invalid frame check sequences.

  • Dual concentric robotic high performance automated tape cartridge system
    Publication number: 20030063966
    Abstract: A data storage and retrieval system. In a preferred embodiment, the data storage and retrieval system includes a polygonal array of cells that are inwardly disposed with openings configured to receive data storage units. A first robot unit to transport a data storage unit to and from the polygonal array of cells is located within the polygonal array of cells. A second robot unit is also located within the polygonal array of cells to transport a data storage unit to and from the polygonal array of cells. The second robot unit manipulates the data storage units placed in the cylindrical array of cells independently of the first robot unit.
