摘要： 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.

摘要： A lamp shade soldering aid is used when soldering a stained glass lamp shade. The soldering aid includes a spindle, inserted through an arm, a base, a turn table, and a clamping member. A lamp shade to be soldered is inserted on the spindle and rests on the turntable, held by the clamping member. The turntable has a plurality of pivoting support members for use with the lamp shade when soldering the interior of the shade. The clamping member does not spin off of the spindle. When the lamp shade is turned, the turntable is also turned. The soldering aid provides for angular motion, such that any seam of the shade may be held in a horizontal position. The soldering aid also provides for rotating motion, such that the lamp shade may be rotated to a next seam.
