Abstract: A multiport splitter with a circuit that is less costly, smaller, impedance matched on all ports, provides 9.54 dB isolation between neighboring ports, and is balanced as compared to the current typical implementations. The present disclosure may further provide a single multiport splitter that may be increased to any suitable number of output ports without the need for cascading multiple splitters and/or couplers together in a single device.

Abstract: A system and associated method determines the characteristics of an electric network including distance to a fault through the use of a power divider and a measuring device that measures a quantity from which voltage magnitude can be determined. The measuring device may be a power detector. The power detector may include a power meter to measure voltage and/or a power sensor to measure amplitude. Then, the results from the power detector are used in conjunction with a Hilbert transform to estimate the phase associated with at least two voltage magnitudes when a combined signal is a minimum phase signal.

Abstract: A stackable horn configured such that a plurality of substantially identical horns can be stacked to form an array. Each horn diminishes in interior area from a mouth to a throat thereof and is vertically taller and longitudinally deeper than it is wide. The horn or array may be secured to a support. In the array, the horns are similar or identical and are arranged side-by-side with a space in between or in abutting contact. An aperture is defined in the throat of each horn and a microphone is positioned within the throat of each horn in the array. The arrangement of horns in the array permits beamforming and as a result allows simultaneous detection, tracking, and identification of multiple targets. Listening distance is greatly increased by utilizing the horn or the array of horns.

IPC: G01R27/26
Abstract: A system and method for analyzing a device under test is provided. The system includes a signal source for generating an incident signal. The incident signal is routed to one or more inputs of the device under test. The system further includes signal separation and routing circuitry for measuring a portion of the incident signal to provide a reference signal and for separating the incident signal and a reflected signal at the one or more inputs of the device under test. The signal separation circuitry for separating the incident signal and the reflected signal at the input of the device under test is accomplished by a resistive device. The system may further include sampling device operationally coupled to the resistive device. The system and method may further include a signal switching mechanism for sequentially routing time slices of two or more signals to be coherently compared.
