Abstract: A method for eliminating or reducing interference in a receiver, for example, interference in a satellite positioning system receiver caused by a co-located TDMA transmitter, including detecting (210) the presence of a jamming signal, generating a synchronous blanking signal (220), and reducing the jamming signal by blanking (230) the receiver with a blanking signal. In one embodiment, the jamming signal is detected in the receiver, for example, at a correlator output of a satellite positioning system receiver.

Abstract: A method for controlling an emission current (134) in a field emission display (100) includes measuring an emission current (134), measuring a portion of the plurality of pixels receiving emission current (134) as a percentage of the plurality of pixels on the anode (138) to define a set point, comparing measured value to set point value and adjusting gate voltage to cause emission current to approach set point value. A field emission display (100) includes a control circuit (111), which has an analog-to-digital converter (150), a current controller (154), as display timing controller (151) and a gate voltage source (158). Analog-to-digital converter (150) is designed to be connected to power supply (146). Gate voltage source (158) is connected to gate extraction electrode (126) and applies thereto the offset voltage, which is manipulated by current controller (154) in response to an output signal (152) of analog-to-digital converter (150) and an output signal of display timing controller (151).
