  • Patent number: 11728796
    Abstract: An inverted group delay circuit is provided. The inverted group delay circuit can offset a group delay between a pair of signals. In a non-limiting example, the inverted group delay circuit can be configured to offset a group delay (e.g., negative group delay) between a time-variant voltage and a time-variant envelope of an analog signal. More specifically, the inverted group delay circuit can output an inverted time-variant voltage having an opposing phase and time-adjusted relative to the time-variant voltage to thereby offset the group delay between the time-variant voltage and the time-variant envelope. As such, the inverted group delay circuit can be provided in a power management integrated circuit (PMIC) to improve timing alignment between a time-variant voltage(s) and a time-variant analog signal(s) at a power amplifier(s), thus helping to reduce potential amplitude distortion when the analog signal(s) is amplified by the power amplifier(s).

  • Patent number: 11668789
    Abstract: A radar system and method include a sparse array receive element and a processing device. The system performs a beamforming operation on a received radar signal to generate a beamforming spectrum, which contains superposed impulse responses with relative power and angle. The processing device executes an iterative detection routine, starting with a first stage detection that compares the beamforming spectrum to an active power threshold and identifies tentative detection points. In the second stage detection, the processing device determines a certain detection point with the greatest relative power and updates the active power threshold for subsequent iterations of the detection routine. The update involves centering the impulse response related to the certain detection point around its angle, multiplying the relative power by the impulse response, and summing the product with the active power threshold. This process continues until a final set of detection points is obtained.

  • Patent number: 11593610
    Abstract: An aircraft noise monitoring system uses a set of geographically distributed noise sensors to receive data corresponding to events captured by the noise sensors. Each event corresponds to noise that exceeds a threshold level. For each event, the system will receive a classification of the event as an aircraft noise event or a non-aircraft noise event. It will then use the data corresponding to the events and the received classifications to train a convolutional neural network (CNN) in a classification process. After training, when the system receives a new noise event, it will use the CNN to classify the new noise event as an aircraft noise event or a non-aircraft noise event, and it will generate an output indicating whether the new noise event is an aircraft noise event or a non-aircraft noise event.

    Abstract: Conventionally, in order to obtain a difference signal between an A+N signal and an N signal and a difference signal between an A+B+N signal and the A+N signal, the A+N signal needs to be held in two different capacitors. Hence, there is a problem in that, due to variations in capacitance of the two capacitors, the difference signal between the A+N signal and the N signal and the difference signal between the A+B+N signal and the A+N signal may not accurately be obtained. An imaging device generates a signal obtained by subtracting the same digital N signal from each of the digital A+N signal and the digital A+B+N signal.

    Abstract: A system is provided for detecting the passage of vehicles and the classification thereof by weight using geophone outputs and a unique density measurement in which the number of peaks of the geophone signal above a predetermined threshold over a number of time frames indicates the presence of a vehicle, with the number of time frames in which the density exceeds the threshold indicating whether the vehicle is a heavy vehicle such as a tank, or a light vehicle such as a car, with the threshold eliminating both manmade and natural noise, as well as distinguishing seismic vibrations due to personnel and animals. In one embodiment, various thresholds are utilized to detect the onset of vehicle presence and the end of the event.

  • Patent number: 8339257
    Abstract: A firearm equipped with a capability of wireless communication reports a discharge of the firearm to a reporting center terminal via a wireless communication link. The firearm includes a firearm housing including a trigger assembly. A sensor is coupled to the firearm housing for sensing the discharge of the firearm. The housing, e.g., portion of a pistol grip, also encases a wireless communication unit for transmitting a message indicating occurence of the firearm discharge to the terminal via wireless communication network. A GPS receiver installed in the firearm receives GPS signals from GPS satellites to enable calculation of the location of the firearm, either at the firearm or by a Position Determining Equipment (PDE), to identify the location of the firearm to the reporting center terminal. Upon detection of the discharge of the firearm, the firearm initiates activities of the GPS receiver and the wireless communication unit.

  • Patent number: 8330614
    Abstract: A telemetry system is described in which a plurality of channels are coupled to a bus. A control subsystem controls the channels so that one of the channels presents to the bus during its designated time period a channel characteristic. The control subsystem interrogates in the analog domain each of the channels during its designated time period, and forms a signal representative of the channel characteristic. The control subsystem may combine one or more of the signals into a digital packet, and transmit the same via transceiver over a wireless network. The channels may be contained within a submersible enclosure and displaced at intervals along the bus, thereby forming an array for monitoring waterborne threats. The array may lie along an ocean floor, may be towed by a marine vehicle, or may suspended from a deployable buoy containing the control subsystem, transceiver, and a remote power source. The array may further comprise a defensive countermeasure deployable responsive to detecting a threat.

  • Patent number: 8331195
    Abstract: A computer implemented method, program and system utilizing a number of field-deployed sensors to accurately detect and classify objects/events (targets) of interest within a sensor field including the detection/classification of human beings travelling on-foot or with vehicles and their direction(s) of travel. In particular, the method, computer program and system are operable to determine whether a detected target is an animal, human or vehicle via analysis of received acoustic and sensor data. The analyses performed include comparison/correlation of the sensor data to known seismic cyclostationary signatures, acoustic and seismic characteristics of human footsteps and travel tendencies, and acoustic and seismic characteristics of non-human (animal) footsteps and travel tendencies.

  • Patent number: 8073634
    Abstract: A signal analysis method extracts transient target signals of known type from a raw data source signal that contains an unknown number of target signals. The method can enhance the analysis of data obtained from in-line oil-debris sensors. The method comprises steps of: defining signatures of the known target signal, and of at least one of the intrinsic noise and interfering signals; performing a mathematical transform that decomposes the raw data into distinct data sets; using the signal signatures to identify and nullify the data sets containing noise and interfering signal signatures; using the target signal signatures to identify the data sets containing target signal components, or may further use a thresholding rule to remove intrinsic noise from said data sets, and finally applying the inverse transform to the processed data sets in order to reconstruct an enhanced output signal.
