    摘要： An antenna array for use within a microwave imaging system includes a plurality of reflecting antenna elements, each capable of being programmed with respective phase-shifts in a first pattern to direct a first beam of microwave radiation towards a first target, and each being capable of being programmed with respective phase-shifts in a second pattern to direct a second beam of microwave radiation towards a second target. To capture a microwave image of an object, the antenna elements are programmed with respective phase-shifts in an interleaved pattern including a portion of the first pattern and a portion of the second pattern.

    摘要： A bottle retaining mechanism holds a culture bottle in place in a cell in an incubating apparatus which agitates the culture bottle and detects the growth of microorganisms in the culture bottle. When a bottle is not present in the cell of the apparatus, the retaining mechanism moves to a position which reflects light from the light emitter to the light detector in an amount greater than the amount of light reflected off of a bottle when present, so as to indicate when a bottle is not present in a cavity of the bottle holder. The retaining mechanism/reflectance flag also is capable of providing a reference signal for auto-calibration purposes. The amount of light reflected from the retaining mechanism/reflectance flag to the light detector in a cell when no bottle is present can be monitored in order to detect changes in the cell. By monitoring such changes in the empty cell, drift from the original cell calibration can be monitored. Based on the magnitude of the measured changes, small changes could be compensated for, whereas large changes could indicate that a cell must be replaced.

    摘要： A lanthanum aluminate (LaAlO.sub.3) substrate on which thin films of layered perovskite copper oxide superconductors are formed. Lanthanum aluminate, with a pseudo-cubic perovskite crystal structure, has a crystal structure and lattice constant that closely match the crystal structures and lattice constants of the layered perovskite superconductors. Therefore, it promotes epitaxial film growth of the superconductors, with the crystals being oriented in the proper direction for good superconductive electrical properties, such as a high critical current density. In addition, LaAlO.sub.3 has good high frequency properties, such as a low loss tangent and low dielectric constant at superconductive temperatures. Finally, lanthanum aluminate does not significantly interact with the superconductors. Lanthanum aluminate can also be used to form thin insulating films between the superconductor layers, which allows for the fabrication of a wide variety of superconductor circuit elements.

    摘要： A superconducting analog-to digital converter comprises an input line, a soliton generator, a phase sampler, and a decoder. The soliton generator includes a nonlinear transmission line and a gradient current source. The transmission line is a series of inductive links separated from a superconducting ground plane by Josephson junction. The gradient current source induces gradient pump currents that are inductively coupled into the transmission line. The gradient establishes a three-cycle soliton. A time-varying current input signal is inductively coupled to the transmission line so that the local pump current changes as a function of changes in the input signal. These changes cause the soliton to move, and thus change its phase, along the transmission line. Sixty-four comparators of the phase sampler track the phase of the soliton. The digital readout of the phase sampler is then decoded to determine the value of the signal input. This configuration provides for 6-7 bits of subquantum resolution so that the ADC is well suited as an interpolator for grosser ADCs.
