摘要:
An impact-acoustic method for testing a tire is provided along with a tire anomaly detection system in which an actuatable impactor is provided with an acoustic transducer and a force transducer. A plurality of discriminator quantities is calculated from acoustic signals and force signals and the calculated discriminator quantities are compared with stored discriminator quantities to determine whether an anomaly is present in the tire.

An apparatus for controlling a log-structured data storage system, operable with a first log-structured data storage area for storing data, comprises a metadata storage component for controlling the first log-structured data storage area and comprising a second log-structured data storage area for storing metadata; and means for nesting the second log-structured data storage area for storing metadata within the first log-structured data storage area. The apparatus may further comprise at least a third log-structured data storage area for storing further metadata, and means for nesting the at least a third log-structured data storage area within the second log-structured data storage area.

A Redundant Array of Independent Disks (RAID) controller receives new data that is to be written, wherein the new data is indicated in blocks of a first block size. The RAID controller reads old data, and old parity that corresponds to the old data, stored in blocks of a second block size that is larger in size than the first block size. The RAID controller computes new parity based on the new data, the old data, and the old parity. The RAID controller writes the new data and the new parity aligned to the blocks of the second block size, wherein portions of the old data that are not overwritten by the RAID controller are also written to the blocks of the second block size.

A method and apparatus for relating a device name to a physical location of a device (202) on a network is provided. The network may be a serial loop network, for example a Fibre Channel Arbitrated Loop network. The network includes a plurality of devices (202) on or connected to the network (201) and a control device (205) with control over at least one of the devices (202). Each device (202) has a check output (204) independent of the network (201) with connection means (206) to a control device (205). The method includes the step of sending a device name from the check output (204) of a device (202) to the control device (205). The check output (204) of a device (202) is also connected to an external indication means for indicating the failure of the device (202).

A system for detecting write errors in a storage device is disclosed. The system comprises a storage device; within the storage device, means for storing one or more data blocks in a storage group, the storage group comprising the one or more data blocks and a check block, wherein the check block comprises one of the group of: a combination of the one or more data blocks of the storage group, a combination of one or more bits of a logical block address associated with the storage group, and a combination of one or more bits of a phase field that is updated each time the storage group is written; means for updating the check block each time the storage group is written; and means for detecting write errors by checking the check block.

A copy engine (104) is provided as an interface between firmware (108) and memory space (106) for carrying out copy operations. The copy engine has a first register (202, 203) to point to a first address and a second register (204, 205) to point to a second address. One of the first and second addresses is a source address and one is a destination address for data to be copied. The copy engine (104) also has a control register (201). The control register (201) includes a count of the amount of memory space required by a copy operation, an indication of the direction of the copy operation from the first address to the second address or from the second address to the first address, and an indication of whether the first memory address is incremented or decremented. The copy engine (104) includes a locking mechanism for locking the copy engine (104) during a copy operation. The copy engine (104) also includes a serialisation mechanism in which a write is made to the control register (201) of zero count. If the copy engine (104) is locked, the write of zero count is retried until the existing copy operation has completed and then it will complete with no effect.
摘要:
The present invention provides cell culture media formulations which support the in vitro cultivation of animal epithelial cells. The media comprise at least one fibroblast growth factor (FGF) and at least one agent that induces increased intracellular cAMP levels, and optionally comprise ascorbic acid. The present invention also provides methods of cultivating animal epithelial cells in vitro using these cell culture media formulations, kits comprising the media, cell culture compositions comprising the culture media and an animal epithelial cell, and compositions that may be used as replacements for organ or gland extracts in animal cell culture media.
