Abstract: A system and a method achieve a higher level of stable gain for a cellular telephone booster (repeater) than previously considered to be achievable. An RF signal booster includes active stability control provided by an active stability network. The active stability network decreases the amount of radiated or conducted parasitic signal coupled from the output of an amplifier back to the input of the amplifier. The active stability network allows a higher system gain than would otherwise be achievable. In one embodiment, the active stability network (stabilization network) includes an RF sample coupler, one or more band pass filters, a vector modulator, an RF recombining coupler and an RF detection circuit. An algorithm controls the stabilization network to minimize the amount of parasitic coupled signal from the output of the amplifier back to the input of the amplifier and to maximize the achievable system gain.

Abstract: The present invention relates to a digital album having a hard drive and built-in scanner configured to scan photographic prints or documents. The digital album allows a user to save the photographic prints or scanned documents as digital images on the hard drive, or another medium, and then view individual images or play photo album slideshows comprising a plurality of digital images. Additionally, a user may upload digital images from an external medium to the hard drive of the photo album, and then view those images and/or include them in a playlist. The digital album of the present invention advantageously allows a user to scan photographic prints or documents, upload or download digital images, and view digital images individually or in an album format, in a substantially automated manner and without the need for complex peripheral devices.
