Abstract: A method and apparatus for minimizing errors in a sensor device due to signal amplitude variation are disclosed herein. A signal output from the sensor device is amplified and, thereafter, AC-coupled to a comparator such that the amplification and AC-coupling of the signal minimize offset shift-related errors associated with the sensor device. The signal can be coupled to eliminate offset shifts due to component mismatches, calibration, aging and/or temperature associated with the sensor device. An AC-coupled sensor signal conditioning circuit is utilized to amplify the signal through an amplifier and then AC-couple the signal to a comparator.

Abstract: An apparatus and method for concealing data bursts in an analog scrambler using parts of the audio of a signal in substitution for the data bursts. What otherwise would be periodic data bursts appearing at the audio output are replaced with selected portions from audio portions of the multiplexed signal. Preferably the replaced audio samples come from immediately past and immediately future portions of the audio of the signal. The data bursts are therefore effectively concealed from the audio output which improves on the degradation of audio otherwise caused by the data bursts that are mixed in periodically with the audio portions of the signal.

Abstract: The present invention discloses a method and apparatus for electronically deterring an animal from approaching an exclusion area around an exclusion unit or from entering or leaving an area bounded by a wire. The animal is provided with a collar unit, which includes a sensor adapted to sense the strength of electromagnetic signals generated by the exclusion unit or wire and a correction unit adapted to provide correction to the animal in response to a sensor output. The portable unit reports to a central controller which selects a correction strategy, such as level of correction to be applied to the animal approaching the perimeter. The controller provides warnings to the user, including warnings for when the battery in the collar unit goes low and when the animal stays in a correction zone for too long. The controller may control a number of exclusion units and/or power units, and may select an appropriate correction for one of a plurality of animals.

Abstract: A system and method for canceling both an echo signal and a spurious sinusoidal signal, such as a telephone dialtone or a carrier signal, from a return signal in a communications system involves producing a replica of the echo signal using an adaptive filter and producing a replica of the sinusoidal signal using an oscillator circuit. The replicas are subtracted from the return signal. The magnitude and phase of the sinusoidal signal are determined by generating a signal that is close in frequency to the expected frequency of the sinusoid and then correlating it to the return signal. The correlation produces a replica of the sinusoid.
