Latest Patents

James R Barnes holds a patent for a self-calibrating threshold detector. This invention is designed for use with receivers that are adapted to receive an incoming transmitted signal carrying a prescribed code. The detector features a single demodulating channel that includes a mixer, which receives the incoming signal and a local replica code. During a brief time interval, an incorrect local code is applied to the mixer, allowing for the incorrect demodulation of the incoming signal. This process provides a reference level that calibrates the noise propagating through the channel. A sample-and-hold circuit is connected to the channel to store a sample of the reference level. During a longer time interval, the correct replica code generates an output level that ranges between the reference level and a maximum level, indicating the presence of the incoming signal and its synchronism with the replica code. A summer subtracts the stored sample reference from the output level to produce a resultant difference signal that indicates the acquisition of the expected signal.
