Abstract: An array (48, 49, 50, 51) of fiber optic couplers coupling an input (45) and an output (46) waveguide. The output waveguide (46) is routed among the couplers of the array such that either backward or forward coupling exists. With backward coupling, energy coupled into the output waveguide (46) in a coupler of the array is guided back to the preceding coupler for coupling back into the input waveguide (45). The backward coupling allows recirculations to occur between couplers to create poles and zeroes in the transfer function of the array which transfer function can be programmed or tailored somewhat to have specific characteristics. Further, the backward coupling allows the array to be used for matrix-vector multiplication.

Granted: 1991-02-07
Abstract: In a method and apparatus for generating a signal proportional to flow in a pipe using probes strapped onto the exterior of the pipe, two ultrasonic pulse trains at a carrier frequency are sent in opposite directions from one probe to the other. Two lower frequency signals are extracted from the two respective pulse trains and analyzed to detect a phase difference. The phase difference corresponds to a difference in the travel times for the two pulse trains caused by the flow velocity in the pipe. The two lower frequency signals are converted to digital data samples which are stored with reference timing data. A microelectronic processor synchronizes the two sampled waves, using the timing data, before comparing the sampled waves to determine the phase difference. The processor and associated circuitry also measure the travel times of the two ultrasonic pulse trains and generate an output signal proportional to flow based on the measured phase difference and the measured travel times.

Abstract: The invention disclosed relates to an electrochemical assay which is particularly concerned with an assay for the presence of, or amount of, glycosylated haemoglobin in a blood sample, but which extends a general assay for detecting the presence of, monitoring the level of or determining the concentration of compounds containing cis-diol groups, such as glycols, nucleic acid components, sugars, polyols, catechols and glycosylated proteins.When ferrocene boronic acid or a derivative thereof is present free in solution, it can act as a mediator for a wide range of oxido-reductases. Howeverin the presence of, for example. sugars containing the cis-diol structure, the metallocine (such as ferrocene boronic acid) covalently binds to the sugar. When the ferrocene boronic acid is thus bound, it is essentially immobilized and its properties as a mediator and ability to diffuse will be markedly affected.
