Abstract: The disclosed embodiments generally use multiple QRNGs contained within independent servers operating in a round-robin fashion via an Application Programming Interface (API) such that the quality of the random number bitstream can be enhanced due to a sum of entropy being gathered across multiple QRNGs that are multiplicative in nature. This allows for multiple modes of operation to be accomplished, the first being a higher overall random stream bitrate, the second being an enhanced entropy stream where output from the independent QRNGs are interleaved together to improve the quality of the random bitstream, and the third mode of operation where a minimum guaranteed random bitstream rate is maintained equal to the redundancy value chosen by the operator based upon the quantity of QRNG devices within the system.

Abstract: A system for crafting railroad crossties of compressed bamboo is described. The system employs a hydraulic press configured to effectively compress multiple stalks of bamboo into a strong unified beam within a mold. Bamboo is first mashed, dried, and treated. A resin is employed as a permanent adhesive, binding the stalks together. The bamboo is stacked within a mold and compressed under the pressure exerted by the hydraulic press. An oven is used to heat the compressed bamboo, and then the bamboo is cooled. The compressed bamboo beam may then be trimmed to remove excess bamboo, and is cut into crosstie segments if needed. The resulting crosstie is sturdy, ecologically friendly, and rapidly manufactured.

Abstract: This invention relates to signal conditioning circuitry 14a for an optical pointing device, the circuitry comprising: means 15a for determining the rate of change of a signal generated on periodic illumination of a photodetector, and outputting a signal representative of said determined rate of change; and means 17a for comparing the signal output by said determining means to a reference voltage.

Abstract: A high voltage pulse generator utilizes an even number of Marx cells using L-C inversion topology. Each Marx cell is associated with an individual inverter transformer having a primary winding connected to the output of an ac power supply such as a series resonant inverter. The secondary of each inverter transformer is half-wave rectified to charge the energy storage capacitors in each Marx cell. A distributed voltage sensing scheme can be provided for accurate feedback to the inverter's controller. An inductive element can be used to achieve a magnetic diode effect in the L-C inversion circuit to reduce component stress and improve efficiency. A transformer-coupled floating gate drive circuit is used to provide local power conditioning and trigger timing for discharge of the energy storage capacitors.

Abstract: A turbine blade for a gas turbine has a hollow airfoil extending from a platform. There is a fillet between the airfoil and the platform, both on the pressure side and on the suction side of the airfoil. The fillet contains a cooling bore extending along part of the length of the fillet, having a first end communicating with the interior of the turbine blade for receiving a gaseous coolant and a second end communicating with the exterior of the turbine blade. The cooling may be formed by electro-discharge machining.

Abstract: A graphics digitizer having a phase-locked-loop, a timing generator, and at least one channel with a reference and bias voltage generator and an analog-to-digital converter is disclosed. In some embodiments, the phase-locked-loop includes a programmable Div/N circuit so that the output frequency of the signal generated by the phase-locked-loop is programmable. In some embodiments, the timing generator generates a HSOUT video signal in response to the HSYNC video signal by sampling the HSYNC video signal with a phase adaptively chosen in response to a programmable phase between the signal generated by the phase-locked-loop and the HSYNC video signal. In some embodiments of the invention the reference and bias voltage generates a reference voltage determined by a digital-to-analog conversion of a value stored in a programmable gain register and generates a bias voltage proportionally to the reference voltage by a current digital-to-analog conversion of a value stored in a programmable offset register.
