    摘要： A method for determining impedance includes receiving a time varying voltage signal from a biosensor and receiving a time varying current signal from the biosensor. The time varying voltage signal and the time varying current signal are transformed to a domain that represents complex values. The impedance representative of the biosensor based upon the transformed time varying voltage signal and the time varying current signal is calculated.

    摘要： A method of detecting a splice in an optical fiber in the presence of noise generates a nulling filter from a segment of a signal received from the optical filter by determining a set of coefficients having an initial "1" followed by p-1 "0" values and w.sub.i finite impulse response filter values, where p is a prediction interval greater than the width of an expected splice signature. The received signal is processed by the nulling filter to remove exponentials from the received signal, leaving an error signal containing noise and splice information. The resulting error signal is processed by a correlation filter to reduce the noise in the error signal. The output from the correlation filter results in a noise reduced error signal with the splice appearing as a noticeable dip in the waveform. The waveform is passed through a threshold detector to identify the splice when the dip exceeds a predetermined threshold.

    摘要： An image processing system processes light conveying visual pattern information represented by individual light rays. The system includes an optical assembly having an input surface and an output surface. The input and output surfaces define a plurality of input and output positions, respectively, for the light rays to enter and exit, respectively, the assembly. The assembly includes a light-shifting apparatus operable so that a respective one of the light rays entering a respective one of the input positions is selectively shiftable by the apparatus in a first direction and, subsequently, in a second direction angled with respect to the first direction from a preceding one to another of the output positions. The assembly is further operable so that following each shifting operation, a respective one of the light rays transmitted by the assembly from an arbitrarily selected one of the output positions is solely derived from the light received from a single one of the input positions.
