  • Patent number: 6952601
    Abstract: A portable terminal having personal computing capability and wireless telecommunications capability. The portable terminal includes a display that is integral with, or otherwise attached to, a display. A housing is rotatably-coupled to the base and/or display. The portable terminal can be closed, wherein the housing overlies the base, or open, wherein base and housing flank the display. The display is fully visible to a user whether the portable terminal is open or closed. When open, a keyboard having keys that are apportioned between the housing and the base is accessible. To accommodate a change in the way in which a user is likely to hold and view the portable terminal when it's closed versus when it's open, the image in the display screen is rotated on command, or automatically, when the portable terminal is opened.

  • Patent number: 5758269
    Abstract: A high-efficient configurable power amplifier suitable for use in amplifying a signal for wireless transmission by a portable unit is provided. The amplifier provides a variable power output level, maximum efficiency of operation and battery power savings for the portable unit. The configurable power amplifier includes a plurality of amplifier stages with each stage having its own output configuration so that a selected number of desired output power levels for the power amplifier may be obtained directly from a selected amplifier stage. The amplifier stages also may be configured in tandem such that the output of a first amplifier stage serves as an input to a second amplifier stage, and so forth, in order to obtain a broad range of selectable power output levels while maintaining the desired efficiency of operation.
