A network arrangement that employs a cache having copies distributed among a plurality of different locations. The cache stores state information for a session with any of the server devices so that it is accessible to at least one other server device. Using this arrangement, when a client device switches from a connection with a first server device to a connection with a second server device, the second server device can retrieve state information from the cache corresponding to the session between the client device and the first server device. The second server device can then use the retrieved state information to accept a session with the client device.

A substrate transfer device includes a pick which has positioning pins to position a substrate and holds a positioned substrate; a drive unit which drives the pick such that the substrate is loaded/unloaded to/from a vacuum processing unit by using a pick; and a transfer control unit which controls a transfer operation of the substrate using the pick. The transfer control unit obtains in advance information on a reference position of the substrate at room temperature when the substrate is loaded into the vacuum processing unit, calculates a positional deviation from the reference position of the substrate when the substrate is loaded into the vacuum processing unit in actual processing, and controls a drive unit such that the substrate is loaded into the vacuum processing unit by correcting the positional deviation.

Techniques for transferring objects between database systems. As implemented in a relational database management system, the techniques employ a data transfer mechanism that operates under control of a master table in the RDBMS that is performing the transfer operation. The master table specifies the kind of transfer operation to be performed, a set of objects to be transferred, operations to be performed on the objects as they are being transferred, and filters for selecting a subset of the objects. During execution of the transfer, the transfer mechanism maintains and updates state in the master table such that queries may be made on the master table to determine the current status of the operation and such that the transfer mechanism may restart the operation after it has been stopped either at the request of a client that is performing the operation or because of an error in the transfer. The master table's persistence and the status information it contains permit the client that is performing the operation to detach from the operation without stopping the operation and later again attach to the operation to determine the operation's status or to perform operations such as creating new files for the operation or changing the degree of parallelism with which the transfer operation is being performed. Another feature of the transfer mechanism is using an object's metadata to determine the most efficient way of transferring the object.

File operations on files in a peripheral system are controlled by an intelligent controller with a file processor. The files are accessed as if the intelligent controller were an addressable virtual storage space. This is accomplished first by communicating controller commands for the intelligent controller through read/write commands addressed to a Command Region of a virtual storage device. The controller commands set up a Mapped Data Region in the virtual storage device for use in controlling data transfer operations to and from the peripheral system. With the Mapped Data Regions set up, blocks of data are transferred between the host and the intelligent controller in response to read/write commands addressed to the Mapped Data Region of the virtual storage device.In an additional feature of the invention file operations are communicated between host and controller through a device driver at the host and a device emulator at the intelligent controller. If the address in the device write/read command is pointing to the Command Region of the virtual storage device, a Command Region process interprets and implements the controller operation required by the controller command embedded in the device write/read command. One of these controller commands causes the Command Region processor to map a requested file to a Mapped Data Region in the virtual storage device. If the address detected by the detecting operation is in a Mapped Data Region, a Mapped Data Region process is called. The Mapped Data Region process reads or writes requested data of a file mapped to the Mapped Data Region addressed by the read/write command. This mapped file read or write is accomplished as a transfer of data over a data path separate from a control path. In an additional feature of the invention, the data transfer between host system and intelligent controller is accomplished by performing a direct memory access transfer of data.

Part of the latency from memory read or write operations is for data to be input to or output from the data latches of the memory via an I/O bus. Methods and circuitry are present for improving performance in non-volatile memory devices by allowing the memory to perform some of these data caching and transfer operations in the background while the memory core is busy with a read operation. A scheme for caching read data is implemented so that even when the read for a current page on a current wordline must be preceded by a prerequisite read of data on an adjacent wordline, the prerequisite read along with any I/O access is preemptively done in the cycle for reading a previous page so that the current read can be performed while the previously read page is busy with the I/O access.

An integrated Internet camera includes, as embedded components contained within the camera body and controlled by a microcontroller, at least a network interface device for connecting to the Internet, a transport control device for packetizing according to Internet protocols, a file transfer device for communicating with a destination user directory on the Internet, and a transmission initiating device for initiating the connection and transfer operations of the file transfer device and transport control device. The network interface device may be a modem, network adapter, or adapter for connection to the Internet. Upon capturing the digital image, the camera initiates a connection to the Internet, connects to the destination user directory, and uploads the digital images. Thereafter, the digital images are available to authorized (or any) user having access to the Internet.

A method for sensing and regulating the level of synchronization between a file of audit blocks generated in a primary host for transfer to a secondary host. The audit files in a primary host are divided into audit blocks which are each identified with an audit block serial number. The individual audit blocks are transmitted through a network from a primary host to a secondary host wherein a tracker mechanism monitors the difference between the number of received audit blocks and the number of generated audit blocks residing at the primary host waiting to be transferred. When the disparity between the audit blocks received and the generated audit blocks waiting to be transmitted reaches a certain critical level, the tracker mechanism will initiate an advance speed up program to expedite the transfer in order to bring the primary and secondary audit files into greater synchronism. Further, the acknowledgment level can be set to indicate the number of audit blocks received in the secondary host for information back to the primary host and the acknowledgment level can be utilized in order to preset a critical value which will indicate that the speed up transfer operation should be initiated.

A method facilitating the transfer of information from a media or data capture device to a larger device while providing valuable feedback about the transfer is described. A transfer device including a simple user interface that can be easily implemented on a media or data capture device provides feedback about the transfer operation, enabling the user to take action when necessary. For example, the user is advised if the transfer is complete or, alternatively, that the transfer has failed and needs to redone. Feedback is provided by visual signals and may also be accompanied by audible signals. All necessary transfer functionality is included on the media capture device, thereby avoiding the requirement for dedicated software on a host (or pipeline) device, such as a cellular phone. This expands the number of pipeline devices that can be utilized with particular media capture devices. As long as there is a correct interface between the data capture device and the pipeline device, all the necessary transfer functionality can be included in the data capture device.

A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.
