  • Publication number: 20240371322
    Abstract: Provided is a display substrate. A data writing circuit included in each pixel circuit is coupled to a first scanning line, a switching control line, a data signal line, and a drive circuit. The data writing circuit transmits, under the control of the first scanning line and the switching control line, a data signal provided by the data signal line to the drive circuit, such that the drive circuit drives the coupled light-emitting element to emit light. In the same pixel circuit group, each pixel circuit subgroup is coupled to a different switching control line, and the plurality of coupled data signal lines are coupled to the same data line to receive the data signals from the data line. Thus, each pixel circuit, under the control of the switching control line coupled thereto, receives the data signal provided by the data line for the data signal line coupled thereto.

  • Patent number: 9866556
    Abstract: Techniques are described for a proxy system to provide a client device with transparent access to multiple network file servers. The proxy system may appear to the client device as a single network file server. The proxy may be configured to forward requests received from the client device to multiple servers as well as provide responses from the server back to the client. Further, the proxy system may authenticate itself, as the client, to each of the multiple network servers using authentication credentials supplied by the client. After prompting a user to submit credentials to establish a session with a first network server, the proxy system may send a session timeout error code, prompting the client to submit a fresh authentication request used by the proxy system to establish a session with a second network server.

  • Patent number: 9464348
    Abstract: A method for making a bit-patterned media (BPM) magnetic recording disk by etching the recording layer using a patterned hard mask layer uses glancing angle deposition (GLAD) of additional hard mask material as a capping layer onto the tops of the patterned hard mask pillars while the disk is rotated about an axis orthogonal to the plane of the disk. In one embodiment the capping layer is deposited after the pillars have been only partially eroded during a partial ion-milling of the recording layer. Ion-milling is then again performed to remove the remaining recording layer material. In another embodiment, before ion-milling of the recording layer, the capping layer is deposited onto the tops of the un-eroded hard mask pillars. This increases the lateral dimension of the hard mask pillars so that after ion-milling of the recording layer, the magnetic islands have an increased lateral dimension.

  • Patent number: 8539081
    Abstract: A NAS (Network Attaches Storage) switch authenticates a client on multiple file servers for proxy services. The NAS switch enables proxy services by successively authenticating the client on the file servers using referrals. The NAS switch further comprises a connection manager to establish connections to the client and the file servers, a referral manager to redirect the client for successive authentications, and a transaction manager to perform data transfers with the file servers on behalf of the client. The system components support DFS (Distributed File System), and communicate using a protocol dialect that supports referral mechanisms such as NFSv4 (Network File Server version 4) or CIFS (Common Internet File System). The transaction manager also performs a protocol dialect translation service when the connection manager negotiates one protocol dialect with the client, and a different protocol dialect with the file server.

  • Patent number: 8195627
    Abstract: The present invention provides selective migration in a storage network in accordance with a policy. The policy can include rules that establish which objects are migrated from a source file server to a destination file server based on file attributes (e.g., file type, file size, last access time, frequency of access). For example, large multimedia files that consume I/O bandwidth on expensive or critical file servers, without adding much value to enterprise productivity, can be migrated to a commodity or less critical file server.

  • Patent number: 8131689
    Abstract: A system and method for performing policy-based storage management using data related to access frequency and file attribute accumulation. A switch device provides transparency for transactions between a client and a storage network. The transparency allows objects (e.g., files or directories) to be moved (e.g., migrated) on the storage network without affecting a reference to the object used by the client (e.g., a file handle). A monitoring module generates accumulation data associated with the transactions for use in policy-based management. The accumulation data can describe uses of the file such as how often certain files are accessed, modifications to files such as creations of new directories or files, and other uses.

  • Patent number: 7720796
    Abstract: A NAS switch provides mirroring in a NAS storage network that is transparent to client. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs mirroring of a namespace when during processes such as data migration, data replication, and data snapshot.
