Abstract: The privacy screen for laptop computer is an expandable hood that may be removably attached to a notebook computer. The privacy screen has an elastic fabric cover secured around an expandable frame. The frame has a plurality of telescoping rods attached to connector pieces using ball and socket joints, which allow the frame to expand concurrently in multiple directions. The screen may be assembled before sale, in which case the screen uses a fixed number of pieces in its frame and the fabric cover is permanently secured to the frame, or provided as a kit, in which cut-out sections of the fabric cover allow the end user to assemble the telescoping rods and connecting pieces as desired. The frame may be secured to the laptop using spring-biased clips.

Abstract: A wireless repeater for repeating a wireless signal without necessarily transforming the wireless signal is provided. The wireless repeater includes a plurality of external antennas, each external antenna configured to operate within one or more wireless frequency bands. The wireless repeater includes a plurality of internal antennas, each internal antenna configured to operate within one or more wireless frequency bands associated with the external antennas. An amplifier unit is connected to the external antennas and internal antennas. The amplifier unit is configured to identify a frequency associated with an incoming wireless signal from within a plurality of wireless frequency bands. The amplifier unit also determines a signal strength for the incoming wireless signal and adjusts the signal strength of the incoming wireless signal to compensate for a loss in signal strength between the external antennas and the internal antennas.

Abstract: A method and computer software product for updating a redundant transaction service system, wherein the redundant transaction service system includes a first transaction service device and a second transaction service device. The method comprises removing the first transaction service device from on-line service and installing new software on the first transaction service device. Next, a current database associated with the second transaction service device is transferred to the first transaction service device. The transferred current database is converted into a format associated with the new software. After the transfer and conversion of the current database, the first transaction service device is returned into on-line service.

Abstract: A feedback eliminating device for acoustical instruments is designed to be used with in-hole amplification devices, without the need to modify either the instrument or the amplification device. The device is preferably in the form of a two-piece cover for the sound hole of an acoustical instrument. Used in conjunction with an in-hole amplification device, the device completely covers the sound hole of an acoustical instrument.
