    Abstract: A two-stage pulse tube refrigerator comprises a pressure wave generator-compressor, first stage and second stage regenerators, first stage and second stage pulse tubes, heat exchangers and a hybrid phase shift mechanism for the first and second stage pulse tubes. The second stage phase shift mechanism includes double fixed orifices while the first stage shifter is an arrangement including one of a) 4 valves, b) 5 valves c) 2 active buffers or d) 3 active buffers. The double fixed orifice phase shifter is located either at room temperature or is thermally connected with the first stage cold end. Two-stage pulse tube refrigerators with a hybrid phase shifter have increased second stage regenerator performance at lower temperature. Pressure drop through the valves and compressor power consumption are decreased, and losses from phase interaction between each stage are eliminated.

    Abstract: Methods are disclosed for receiving GPS signals in the presence of multiple interference signals. The methods feature the orthogonal projection of sub-optimal weight vectors onto sets of orthonormal basis vectors. They facilitate the use of single-port reception techniques in which power is monitored only at a single GPS array output port regardless of the number of array elements. The methods do not require prior knowledge of interference signal structure and their use of uncoupled orthonormal basis vectors facilitates the simultaneous adjustment of array weights and rapid convergence to an optimal set of weights.

    Abstract: A non-invasive blood glucose meter includes a near-infrared energy analyzer which includes a light filter assembly of two Fabry-Perot interferometers and a photosensor. The near-infrared energy analyzer detects near-infrared energy absorbed by a human or animal body and generates spectra of such absorption so that the blood glucose content in the body may be analyzed. In order to provide stable energy absorption information of the blood, special designs are provided to stabilize the light source, to calibrate the spectrum and to obviate the noise from the heartbeats of the body. A single crystal silicon elastic power source is used to provide the driving power of the Fabry-Perot interferometer to avoid mechanical hysteresis.

    Abstract: An apparatus and method for continuously monitoring the liquid nitrogen level a liquid nitrogen container and automatically refilling liquid nitrogen from a liquid nitrogen reservoir when the liquid nitrogen in the container falls below a predetermined level. The apparatus comprises a liquid nitrogen level sensing element, which contains a superconducting material, such as a YbaCuO type superconductiing material, disposed on a non-conducting substrate, such as magnesium oxide. The superconducting material is selected such that it has a critical temperature approximately equal to the boiling point temperature of liquid nitrogen. The superconducting material is placed near the predetermined level and, under normal conditions, the superconducting material exhibits zero or near zero resistance. When the level of liquid nitrogen falls below the predetermined level due to heat loss or other reasons, the resistance of the superconducting material will increase substantially, thus triggering a control means to open a solenoid valve and allow liquid nitrogen to flow from the reservoir to the container. The liquid nitrogen level sensing element can be prepared by photochemically etching a superconducting layer, which has been deposited on the non-conducting substrate, in accordance with a serpentine design, to thereby increase the sensitivity and reliability thereof.
