摘要： RF field is sensed to produce an incoming voltage that drives a microarray of electron guns in a sweep pattern towards a detector array. The electron guns emit a beam current that may amplify the incoming voltage signal, and the detector material may be selected to amplify the beam current at the detector, for example, by avalanche and/or cascade in a Schottky material, to provide a low current, high gain amplification. The microarrays may be arranged in various combinations to produce successive amplifications, frequency multipliers, transmit-receive amplifiers, crossbar switches, mixers, beamformers, and selective polarization devices, among other such devices.

摘要： A left-handed nonlinear transmission line system has multiple nonlinear capacitors connected in series between input and output terminals and multiple inductances connected in parallel between the nonlinear capacitors and a return conductor extending between the input and output terminals. The nonlinear capacitors have a capacitance characteristic that changes with the voltage applied across the capacitors, such as a capacitance that decreases with increasing voltage. A radio frequency signal source is coupled to the input terminals and provides power at a selected drive frequency. Depending on the frequency of the drive signal with respect to the Bragg cutoff frequency of the nonlinear transmission line, the output signal may include a strong signal component at the third harmonic of the input drive signal frequency, components at higher harmonics, or components at fractional frequencies of the input drive signal frequency. Parametric generation of other signal waves that are phase matched with the signal wave produced by the input drive signal is also possible under appropriate conditions. The left-handed nonlinear transmission line system generates such output signal frequencies with high efficiency.

摘要： Two bridge type transducers are coupled in series with their outputs each driving one of a pair of differential amplifiers, with the outputs tied together in a push-pull configuration. In further embodiments, push-pull operation is obtained by matching amplifier gain components and using current mirrors. Lower voltage operation may be achieved by simple diode level shifting of the transducer outputs. In one embodiment, the transducers comprise Hall effect sensors.

摘要： A device for eliminating static charge, dust and lint from surfaces by forced convection of electrically ionized air or gas. The device utilizes high voltage direct current and forced convection sources to ionize the air or gas into separate positive and negative flows which are joined into concentric interlaced helical streams in a rotating vortex forming chamber. The rotating streams exit the device into the adjacent atmosphere, whereupon coming in contact with a statically charged surface, they cause the neutralization of the static charge by the alternate passage of the streams of positive and negative ionized air or gas over that surface. The device may also incorporate high velocity jets to additionally convect away dust and lint adhering to a surface.

摘要： A high bandwidth Hall sensor includes a high bandwidth path and a low bandwidth path. The relatively high offset (from sensor offset) of the high bandwidth path is estimated using a relatively low offset generated by the low bandwidth path. The relatively high offset of the high bandwidth path is substantially reduced by combining the output of the high bandwidth path with the output of the low bandwidth path to generate a high bandwidth, low offset output. The offset can be further reduced by including transimpedance amplifiers in the high bandwidth sensors to optimize the frequency response of high bandwidth Hall sensor.

摘要： An amplifier including an electronic tube with an axial electron beam, provided with a cathode and at least two collectors, and at least two sources of DC voltage. Each collector is connected to a DC voltage source having a potential difference such that, the further the collector is from the cathode, the lower the potential difference between this collector and the cathode. The DC voltage sources are connected together at a common point situated at the collector whose potential difference with the cathode is the lower but not zero.
