Abstract: A method of fabrication of a multi-gate semiconductor device that includes providing a fin having a plurality of a first type of epitaxial layers and a plurality of a second type of epitaxial layers. The plurality of the second type of epitaxial layers is oxidized in the source/drain region. A first portion of a first layer of the second type of epitaxial layers is removed in a channel region of the fin to form an opening between a first layer of the first type of epitaxial layer and a second layer of the first type of epitaxial layer. A portion of a gate structure is then formed in the opening.

Abstract: A system includes multiple KVM switches, multiple user consoles and a recording system connected via a network. Each KVM switch facilitates interactions between user consoles and selected servers connected its server ports. The KVM switch transmits keyboard, mouse and video data exchanged between user consoles and servers, and administrative data, to the recording system. The recording system records the keyboard, mouse, video and administrative data, and detects trigger events based on such data. Trigger events include predefined keywords, mouse operations, video images, user IDs and server IDs, or combinations thereof. When a trigger event is detected, the recording system automatically transmits monitoring information to an administrative console via the network. The monitoring information may include combined video data containing information about keyboard and mouse actions superimposed on desktop images. The administrative console may also request specific recorded data for review.

Abstract: In a KVM switch system where multiple servers and clients are connected to one or more KVM switches, dongles (adapters) are connected between each server and the KVM switch. Each dongle is always connected to the same server, and its unique dongle ID can be used to identify the servers. During a communication session between a target server and a client, if the target server is moved from one computer port of the KVM switch system to another, the KVM switch automatically detects the move using dongle IDs, and automatically re-establish communication between the client and the target server via the other computer port, without the client initiating a new connection request. Virtual port numbers are associated with dongle IDs and are used by the on-screen display of the client so that the displayed list of servers is not affected when the servers are moved to different ports.

Abstract: A graphical user interface used in a virtual media system for allowing a server computer to access objects (files and folders) on storage devices of a client computer. The server is controlled by input signals from the client. The desktop of the client displays a first file management window showing objects on the storage devices, and a second window representing a desktop of the server. Using input devices connected to the client, a user selects objects in the first window and drags and drops them on the second window. In response, the client performs a virtual media mounting process to present the selected objects to the server as objects on a local drive of the server, without presenting any unselected content on the storage devices. The local drive is shown in the second window on the client's desktop to allow the user to explore its content.

Abstract: A virtual media (VM) method for mounting one or more folders in one or more storage devices of a client for accessed by a server as a virtual drive. The client assigns virtual cluster indices to each file, and creates a file-cluster index table to store the assigned virtual cluster indices. The client also creates a VM file system complying with the FAT file system standard except that only subdirectories and no data files are stored in the VM FAT file system. The VM FAT table uses virtual cluster indices rather than actual cluster indices. Data written by the server are stored in a temporary data area without modifying the actual file systems of the storage devices. The virtual sectors requested to be written are “dirty”, and the dirty sector numbers and corresponding temporary sector numbers are stored in a dirty sector index table for use in a write-back step.

Abstract: A video data recoding method suitable for recording computer sessions. Each video image frame is divided into multiple blocks. A server processes the video frames and transmits only changed blocks for each frame to a video log server. The video log server stores the changed blocks with block indices in a data file. The video log server also maintains a virtual frame table which stores, for each block of the frame, the data location within the data file where the most recent occurrence of that block is stored. The virtual frame table is continuously updated as changed blocks are stored in the data file. The video log server further stores a snapshot file containing snapshots of the virtual frame table at predetermined time points, along with time stamps and a next changed frame location. The data file and the snapshot file are used to reproduce the video images.
