A system and method is disclosed for creating and exposing virtual disk images to a host server, during a KVM session, using an HTML5 KVM/virtual media client running in a Chrome&#x2122; Web browser of a user's device (e.g., PC workstation). The host server is able to select all or specific portions of the virtual disk image for use, whereupon the bytes representing the selected data content are packaged by the HTML5 KVM/virtual media client using a persistent sandbox and transmitted to the host server. Using the HTML5 KVM/virtual media client to create and expose virtual disk images from the persistent sandbox of the Chrome&#x2122; Web Browser eliminates the problem of the Web browser not being able to directly access physical media (e.g., disks) on the user's device, and further significantly reduces data size limitations on the size of the virtual disk images that may be created.

System and method for creating virtual disk images for use with remote computer

A method is disclosed for providing compressed video to a personal electronic device of a user using one of a plurality of different video compression protocols, and wherein the personal electronic device has a web browser. The method may involve using the personal electronic device to transmit a request for video content from a server via a remotely located controller. The controller may be used to serve up HTML5 client code to the browser. The browser may use the HTML5 client code to create a web socket connection with the server and to establish a web socket in the browser. The HTML5 client code, the web socket connection and the web socket may be used to receive the compressed video, and the HTML5 client code may be used to decompress the compressed video for display on the personal electronic device.

System and method for single KVM client accommodating multiple different video compression technologies

Methods and systems are provided that allow a user to remotely access another computer and view its desktop without regard to whether that desktop has a relatively static image typical of a computer desktop, or whether it is playing a video, such as from a DVD. Relatively static screens may be displayed along with full motion video in such systems. These systems may also provide for both short mouse lag time when full motion video is displayed. In one implementation, hardware and firmware captures and encodes the video from the remote computer, and software on the client computer decodes the encoded video and displays it to the user.

Method and system for remote viewing of static and video images

A method is disclosed for exposing virtual disk images on a user device, which is running an HTML5 KVM virtual media client in a Web browser, and which has established a KVM session with a KVM device associated with a remote device. A selected disk image file is initially obtained by the user device and a message sent to the remote device that the disk image file is available for use. The HTML5 KVM virtual media client exposes the disk image file for use to the remote device, which sends a message to the HTML5 KVM virtual media client requesting a specific portion of the disk image file. The HTML5 KVM virtual media client receives the message and a script engine running in the Web browser creates a new file available to the Web browser of just the portion requested by the remote device, which is then transmitted to the remote device.

A system and method is disclosed for creating and exposing virtual disk images to a host server, during a KVM session, using an HTML5 KVM virtual media client running in the Web browser of a user's device (e.g., PC workstation). The host server is able to select all or specific portions of the virtual disk image for use, whereupon the bytes representing the selected data content are packaged by the HTML5 KVM virtual media client and transmitted to the host server. Using the HTML5 KVM virtual media client to create and expose virtual disk images eliminates the problem of the Web browser not being able to directly access physical media (e.g., disks) on the user's device.

Methods and systems are provided to allow personal computer users to virtualize a local audio device so that they can remotely connect to a server and interact with the server as if the local audio device was physically connected to the server. They connect a remote audio target hardware device to the target system through a physical USB connection, and the device interacts with the local user's computer over a network. The target system is unaware that the audio device is not connected directly to the system through a physical connection, and the target system does not need special software to implement the remote audio device. The audio target hardware device connected to the target computer may be physically connected and disconnected.

Method and system for USB device virtualization

Methods and systems are provided to allow personal computer users to virtualize a local smart card so that they can remotely connect to a server and interact with the server as if the local smart card was physically connected to the server. They connect a remote smart card target hardware device to the target system through a physical connection, such as a USB connection, and the device interacts with the local user's computer and smart card reader over a network. The target system is unaware that the smart card reader is not connected directly to the system through a physical connection, and the target system does not need special software to implement the remote smart card reader. The smart card target device connected to the target computer may be physically connected and disconnected.

Method and system for smart card virtualization

By utilizing a transmitter that plugs into a power socket of a piece of electrical equipment, that equipment may be locatable using a specialized power source that interacts with the transmitter. The specialized power source sends a command signal across a power cable and causes the transmitter to send a response signal. The response signal is received by one or more receivers, and the position of the equipment within its corresponding cabinet/rack can be determined. The response signal can be sent using a number of different techniques, such as ultrasonic or infrared.

System and method for identifying electrical equipment using wireless receivers

A method and system to detect a correlation of movements of an input device, sent from a first location, with at least one configurable movement parameter set on a remote computer at a second location remote from the first location, wherein the method includes: (a) sending first movement information from the first location to the remote computer at the second location, the first movement information corresponding to a first movement of the input device; (b) tracking a resulting movement of a cursor of the remote computer at the second location in response to the remote computer having received the first movement information and utilized the at least one configurable movement parameter; (c) calculating predicted movements utilizing at least two possible values for the at least one configurable movement parameter; and (d) determining which of the at least two possible values provides the predicted movement most closely matching the resulting movement of the cursor.

Input-device movement to cursor movement correlator

An Intelligent Network Peripheral (INP) is equipped with a recording control processor that is connected to at least one internal or external recording device (e.g., hard drive, disk array, CD-recorder, DVD recorder, and/or tape device). Using the INP, a user may be prompted to perform an activity, such as (1) start a new recording session, (2) playback a recorded session, (3) delete a recorded session, (4) edit recording parameters (e.g., the number of stored frames, the length of a session to record, the resolution of the image to record), and (5) re-run a recorded session. An INP may be incorporated into a Keyboard/Video/Mouse (KVM) switch, a Rack Connection Manager (RCM) and/or a Pod Extension Module (PEM) for recording at least one of video from and user input to a computer for diagnostic and other purposes.

Remote session recording apparatus and method

A method for reducing the erroneous display of multiple keystrokes on a target computer, that occur when depressing a key a single time on a Universal Serial Bus (USB) based keyboard from a remote computer. The invention eliminates the time lapse between the key press and key released events to produce single keystrokes on the target computer, instead of erroneous multiple keystrokes.
