Abstract: A computer has a display, keyboard and two main component parts. The components each have an L-shape and are linked together to enable sliding movement in substantially one plane in a first direction. The linkage also enables movement orthogonally with respect to the first direction in another plane, such that the components transition from a closed position of the computer in which the components interfit together to form a first right rectangular prism and in which the display is exposed, to an open position having a second right rectangular prism shape in which the keyboard is exposed adjacent to and in the same plane as the display.

Abstract: A system, computer implemented method, and computer readable storage medium is provided which enables customers of an establishment to collaboratively reject a media file that is currently playing and/or pending to be played within that establishment by entering data into a personal wireless portable computing device on their person, for example a cellular telephone. Upon entering a rejection request, and where necessary an establishment identifier, a message is sent over a wireless link to a media server which performs a series of logical tests to determine if the media file is actually terminated prior to full completion of play. In this way, a plurality of separate customers may use their portable computing devices to collaboratively reject specific musical media file selections that are currently playing or currently pending for play within a particular physical establishment.

Abstract: A backup image generator can create a primary image and periodic delta images of all or part of a primary server. The images can be sent to a network attached storage device and a remote storage server. In the event of a failure of the primary server, the failure can be diagnosed to develop a recovery strategy. Based on the diagnosis, at least one delta image may be applied to a copy of the primary image to generate an updated primary image at either the network attached storage or the remote storage server. The updated primary image may be converted to a virtual server in a physical to virtual conversion at either the network attached storage device or remote storage server and users may be redirected to the virtual server. The updated primary image may also be restored to the primary server in a virtual to physical conversion. As a result, the primary data storage may be timely backed-up, recovered and restored with the possibility of providing server and business continuity in the event of a failure.

The voltage applied through the conductor or electrode 13 is controlled to provide a predetermined bias voltage that changes the electrostatic field of the ceramic 14.

Abstract: A free space optical communication system incorporates a kinematic sensor, such as an accelerometer, proximate an optical signal generator or emitter, such as a laser. Kinematic information generated using an output signal from the kinematic sensor is encoded along with a time signal and transmitted from the sending node to a receiving node. The receiving node receives the kinematic information and determines a future position and orientation of the sending node. The receiving node makes adjustments to receiving optical component hardware in order to better receive the signal based upon the acceleration data and the time signal.

Abstract: Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a flow data structure is established that identifies current packet flows associated with multiple virtual routers in the virtual router-based network device. When an incoming packet is received by the virtual router-based network device, it is then determined whether the incoming packet is associated with a current packet flow by accessing the flow data structure based on a header associated with the incoming packet. If it is determined that the incoming packet is associated with the current packet flow, then the incoming packet is hardware forwarded via a network interface of the virtual router-based network device without intervention by a processor of the virtual router-based network device, otherwise the incoming packet is forwarded to software on the processor for flow learning.
