Abstract: A method, system, and computer readable medium for performing a generalized angle-based tracker for a target determines angle-based information from a target signal, and initializes a Stationary Surface Filter (SSF), a Moving Surface Filter (MSF), and a Pseudorange Kalman Filter (PKF) with the angle-based information. Next, the SSF and MSF are scored by the PKF. If the information is associated, then the SSF, MSF, and PKF are updated. It is determined if at least one plausible Constituent Kalman Filter (CKF) exists for the SSF and MSF. If at least one CKF exists for the SSF and no CKF exists for the MSF, then the target is stationary surface; if at least one CKF exists for the MSF and no CKF exists for the SSF, then the target is moving surface; if no CKF exists for both the SSF and the MSF, then the target is moving airborne.

Abstract: An anomaly detection system is disclosed. In an embodiment, the anomaly detection system includes an anomaly detection module and a warning indicator module. The anomaly detection module includes one or more auto-encoders that receive sensor data from a plurality of sensors. Each of the one or more auto-encoders receives sensor data from at least three different sensors of the plurality of sensors. By receiving data output from at least three of the sensors, the auto-encoder can recognize expected inter-related patterns from the sensor output. The warning indicator module compares an output of a given auto-encoder of the plurality of auto-encoders to an input of the given auto-encoder to obtain an error value, and then compares that error value against an error threshold. In response to the error value exceeding the error threshold, the warning indicator module issues a warning signal associated with the sensor data received by the given auto-encoder.

Abstract: An encapsulation block for a digital signal processing (DSP) block. The encapsulation block includes DSP block having an input terminal, an output terminal, and an input clock. The encapsulation block also includes pacing control network operatively connected with the input terminal, the output terminal, and the input clock of the DSP block. The input terminal of the DSP block is configured to receive a samples-in data stream inputted at a predefined clock period defined by the input clock. The output terminal of the DSP block is configured to receive a samples-out data stream outputted at a predefined paced parameter. The pacing control network is configured to control data flow at the samples-in data stream and the samples-out data stream independently of the DSP block.

Abstract: A switch assembly and a method of effecting a battery to initiate. The switch assembly includes a support that is adapted to operably engage with a battery. The switch assembly also include a slide operably engaged with the support and moveable in a first direction relative to the support between a primed position and a released position. The switch assembly also includes a cover operably engaged with the support and enclosing the slide. The switch assembly also includes a firing pin mechanism operably engaged with the support, the slide, and the cover and moveable in a second direction relative to the slide and the support. In the switch assembly, the second direction of the firing pin mechanism is different than the first direction of the slide.

Abstract: Techniques are provided for a transimpedance amplifier (TIA). A TIA implementing the techniques according to an embodiment includes a pre-amplifier stage configured to amplify an input signal. The pre-amplifier stage includes a first P-channel metal oxide semiconductor field effect transistor (MOSFET) (P1), a second P-channel MOSFET (P2), a first N-channel MOSFET (N1), and a second N-channel MOSFET (N2), coupled in series. The gates of P1 and N2 are driven by the input signal. The output of the pre-amplifier stage is provided at a coupling between the drain of P2 and the drain of N1. The pre-amplifier stage also includes an active resistor network configured to provide a variable resistance based on a provided current bias generated from a gain control signal. The active resistor network is coupled between the gate of P1 and the drain of P2. The variable resistance is used to control the gain of the pre-amplifier stage.

Abstract: A transceiver includes a radio frequency (RF) input, an RF channelized digital receiver, an RF wideband digital receiver, an analog-to-digital converter (ADC)/digital-to-analog converter (DAC), an RF channelized digital transmitter, and an RF output. The RF channelized digital receiver is configured to split an analog RF input signal into a plurality of sub-octave contiguous frequency band channels and to convert the channels to a plurality of first digital signals. The RF wideband receiver is configured to convert the analog RF input signal into a second digital signal. The ADC/DAC is configured to process each of the first and second digital signals to produce a plurality of third digital signals. The RF channelized digital transmitter is configured to convert each of the third digital signals into a plurality of analog output signals, to combine the analog output signals into an analog RF output signal, and to transmit the analog RF output signal.

Abstract: Correlation interferometry direction finding (CIDF) processes that significantly improve processing time and cut memory requirements relative to the current memory requirements are provided herein. The presently disclosed processes further may utilize only the real portion of the correlation coefficient of the RF signal to further increase processing speed and decrease memory requirements while simultaneously improving direction finding accuracy and reducing the number of wild bearings reported.

Abstract: A V-band clamp includes first and second clamp sections each having an arcuate shape with a first end, a second end, and inside surface defining a recessed channel. A hinge pivotably connects the second end of the first clamp section to the first end of the second clamp section. At least one fastener is configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position. When the V-band clamp is in the closed position, each fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section.

Abstract: A method of recognizing a pattern in a signal is provided. The method includes receiving, by a processor and at an input, the signal comprising data; converting, by the processor and based on a plurality of features, the data from the signal into a collection of features; identifying, by the processor, one or more feature-to-feature transitions between features in the collection of features; plotting, by the processor, a directed graph of each of the feature-to-feature transitions, wherein each unique feature in the collection of features is represented by a single vertex and each feature-to-feature transition is represented by a directed edge between two vertices weighted by a corresponding number of each of the feature-to-feature transitions; and detecting, by the processor, a pattern in the data by comparing the weight of each of the feature-to-feature transitions in the directed graph to a user-defined threshold.
