  • Extended user input
    Patent number: 8792231
    Abstract: An apparatus has a first body part, a second body part, and a support mechanism configured to keep the first and second body parts together while enabling a user to move the first and second body parts between a closed configuration and an open configuration. In the closed configuration, the first and second body parts are stacked and the support mechanism is sandwiched between the first and second body parts. The apparatus further has user input equipment positioned such that the user input equipment is behind the first body part and accessible to the user when the first and second body parts are in the open configuration and the user input equipment is not accessible to the user when the first and second body parts are in the closed configuration.

  • Method and apparatus for providing an efficient pilot scheme for channel estimation
    Publication number: 20060140289
    Abstract: An approach for utilizing a pilot scheme in a spread spectrum communication system (e.g., Multi Carrier Code Division Multiple Access (MC-CDMA)) is provided. A communications link includes a sub-bands and a single pilot channel that is designated for the sub-bands for channel estimation. Pilot symbols transmitted over the single pilot channel are used to determine a first channel estimate associated with a first one of the sub-bands, and a second channel estimate corresponding to a second one of the sub-bands is derived from the first channel estimate.
