Systems and methods provide for detection of one or more underground utilities. Radar waves and seismic waves of about the same wavelength are generated and communicated into a subsurface. Radar and seismic response signals resulting from communication of the radar and seismic waves into the subsurface are concurrently received. Data associated with the received radar and seismic response signals are stored. One or more underground utilities within the subsurface is/are detected using the stored data. The underground utilities may include metallic and non-metallic utilities.

Various embodiments of the present invention provide systems and methods for data processing. For example, a variable iteration data processing system is disclosed that includes at least a first detector, a second detector, a decoder, and a queuing buffer. The first detector is operable to perform a data detection on an input data set at a first time. The decoder receives a derivation of an output from the first detector and performs a decoding process. Where the decoding process fails to converge, the decoder output is passed to the second detector for a subsequent detection and decoding process at a second time.

According to one embodiment, a computerized method comprises receiving a set of indicators of compromise (IOCs) associated with a known malware of a first message type from a first source and receiving one or more IOCs (IOC(s)) from a second source that is different from the first source. Thereafter, a determination is made as to whether the received IOC(s) from the second source correspond to the set of IOCs received from the first source. If so, information associated with at least the set of IOCs is used to locate a malware of the first message type that is undetected at the second source.

Apparatuses, systems and methods for transmitting and receiving modulated impulse radio signals. An impulse radio receiver includes a time base, a precision timing generator, a template generator, a delay, first and second correlators, a data detector and a time base adjustor. The time base produces a periodic timing signal that is used by the precision timing generator to produce a timing trigger signal. The template generator uses the timing trigger signal to produce a template signal. A delay receives the template signal and outputs a delayed template signal. When an impulse radio signal is received, the first correlator correlates the received impulse radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse radio signal with the delayed template signal to produce a second correlator output signal. The data detector produces a data signal based on at least the first correlator output signal. The time base adjustor produces a time base adjustment signal based on at least the second correlator output signal. The time base adjustment signal is used to synchronize the time base with the received impulse radio signal.

A monitor camera photographs a whole monitor area for capturing the photographed whole monitor area as high definition image data higher in resolution than a display screen. A new object detection/extraction unit detects a new object in the monitor area based on the high definition image data captured by the monitor camera, extracts partial image data of an area, which contains the new object, from the high definition image data, and obtains location information on the partial image data in relation to the high definition image data. A whole-monitor-area image data down-sampling unit down-samples the high definition image data to produce standard definition image data corresponding to the resolution of the display screen. An image enlargement unit enlarges the standard definition image data based on entered enlargement instruction information. An image combination unit overlaps the partial image data on image data, enlarged by the image enlargement unit, based on the location information and sends resulting image data to the display screen.

An image sensor of an electronic camera photoelectrically converts a subject image obtained by a shooting optical system to generate an image signal. A image processing section generates face registration image data and moving image data. A face detecting section detects a face area inside a shooting screen based on the moving image data. A controlling section adjusts shooting parameters of the shooting optical system, depending on a position detected at the face area. A face image generating section cuts out an image of the face area to generate face image data. A face recognizing data generating section extracts feature points of the face of a captured person from a part of the face area of the face registration image data and generates face recognizing data. A recording section records the face recognizing data or face image data.

The invention relates to a detection system for determining data embedded into the light output of a light source in a form of a repeating sequence of N symbols. The detection system includes a camera and a processing unit. The camera is configured to acquire a series of images of the scene via specific open/closure patterns of the shutter. The processing unit is configured to process the acquired series of images to determine the repeating sequence of N symbols. By carefully triggering when a shutter of the camera is open to capture the different symbols of the encoded light within each frame time of a camera, a conventional camera with a relatively long frame time may be employed. Therefore, the techniques presented herein are suitable for detecting the invisible “high frequency” coded light while using less expensive cameras as those used in the prior art.

A security module on a client monitors file creations at the client and reports heritage data describing the monitored file creations to a security server. A file categorization module at the security server receives file heritage data reports from a plurality of clients. The heritage data reports identify parent files that created executable child files at the clients. The file categorization module filters the heritage data to identify and prioritize parent files that are not categorized. The file categorization module analyzes the uncategorized files in priority order to categorize the files as “expected executable file creators” or “executable file creators of interest.” The file categorization module reports the file categorization data to the security modules of the clients. The security modules use the file categorization data to identify malware at the clients.

A detected 3D camera pose estimator determines a detected 3D camera pose estimate from the camera data, the detected 3D observations and the candidate 2D key points. A first storage stores the detected 2D candidate key points and the 2D image data, and outputs in response to a 3D camera pose estimate output previous 2D image data and candidate 2D key points related to a previous 3D camera pose estimate output.

A tracked 3D observations detector determines tracked 3D observations from the 2D image data, the candidate 2D key points, the camera data, the previous 2D image data and candidate 2D key points, the previous 3D camera pose estimate and 3D scene model data. A pose estimate selector outputs a selected one of the detected camera pose estimate and the previous 3D camera pose estimate. A 3D camera pose estimator computes and outputs the 3D camera pose estimate from the camera data, the detected 3D observations, the tracked 3D observations and the selected 3D camera pose estimate.
