Methods and systems for a high-resolution virtual vehicle presence sensor are discussed herein. For example, the virtual sensor system may include a plurality of sensors analyzing a known path and configured to determine path-based vehicle data corresponding to a path-based vehicle, wherein each sensor of the plurality of sensors is positionally independent of each other sensor in the plurality of sensors. The virtual sensor system may further include a processing element configured to receive the path-based vehicle data from the plurality of sensors, calculate infilling kinematic data of the path-based vehicle at positions between the plurality of sensors based on the path-based vehicle data and known path information corresponding to the known path, and generate a visualization of the infilling kinematic data, the path-based vehicle data, and the known path information. The virtual sensor system may further include a display configured to display the visualization.

A cable protection system is provided that includes mating features for enabling efficient and effective assembly around a cable to be protected. The mating features provide specified hold strengths and releasable features for enabling installers to release the mating features as desired at a later time.

There is disclosed a computer-implemented method of generating audio signals for an array of woofers and an array of tweeters housed in a computing device, the method comprising: receiving a plurality of input audio signals to be reproduced, by the array of woofers and the array of tweeters, at a respective plurality of control points in an acoustic environment; and generating a respective output audio signal for each of the woofers and tweeters by applying one or more cross-talk cancellation algorithms to the plurality of input audio signals to control a pressure at each of the plurality of control points, wherein the array of woofers consists of two woofers and the array of tweeters consists of at least three tweeters.

A patch cord comprising a multi-mode fiber (MMF) having an MMF core diameter, and a photonic crystal fiber (PCF) having a hollow core having a mode field diameter (MFD) that is smaller than the MMF core diameter. The MMF and the PCF are spliced together, and the MMF and the PCF have been actively aligned to maximize the overlap integral of a fundamental mode of the MMF while minimizing the power in other modes.
