Abstract: Estimating electrical parameters of a track circuit including a transmitter, a receiver, and a track section between the transmitter and receiver. The transmitter outputs, over the track section towards the receiver, a signal including a data packet part, and the signal received by the receiver is decoded to determine the data packet received. Simulated signals are generated, via a predetermined software model including parameters of the track circuit, by varying an actual value input for the model parameters, each signal generated corresponding to actual values input for the parameters. Each simulated signal is compared with the signal received at a receiver until finding a part of a simulated signal that matches a corresponding part of the signal received at a receiver. The actual parameter values corresponding to the simulated signal that match the signal received at the receiver are estimated as the actual parameters of the track circuit.

Abstract: An apparatus and method of generating personalized HRTFs. The system is prepared by calculating a model for HRTFs described as the relationship between a finite example set of input data, namely anthropometric measures and demographic information for a set of individuals, and a corresponding set of output data, namely HRTFs numerically simulated using a high-resolution database of 3D scans of the same set of individuals. At the time of use, the system queries the user for their demographic information, and then from a series of images of the user, the system detects and measures various anthropometric characteristics. The system then applies the prepared model to the anthropometric and demographic data as part of generating a personalized HRTF. In this manner, the personalized HRTF can be generated with more convenience than by performing a high-resolution scan or an acoustic measurement of the user, and with less computational complexity than by numerically simulating their HRTF.

Abstract: A modular target having a support pole and a head. The head is preferably removable. The head is configured for removable attachment of a target. The head has a rail onto which a sleeve of a target is attached. The rail is preferably cylindrical. The target is configured with a sleeve that slides over the rail. Preferably a shooting face extends from the sleeve. Further, the shooting face is configured such that a moment arm allows the shooting face to hang at a 5-20 degree angle from vertical, with the preferred angle being 10 degrees. In a preferred embodiment the modular target utilizes a removably head configured with a neck that attaches to a vertical support pole. The vertical support pole preferably has a slide hammer attached that allows for easier placement of the target in the ground. Preferably the support pole has a fin that serves to resist rotation of the support pole when the target is hit by a projectile fired by a firearm.

Abstract: A system for positioning a cartridge is disclosed. The system has a drive rod with a body having a first axis and a groove formed in the body. The groove has a first portion that is not perpendicular to the first axis and a second portion that is perpendicular to the first axis. The system also includes a collar that coupled to the drive rod. The collar has an element configured to engage the groove. Rotation of the drive rod with respect to the collar while the element is engaged in the first portion of the thread causes the collar to move with respect to the first axis. Rotation of the drive rod with respect to the collar while the element is engaged with the second portion of the thread causes the collar to remain stationary with respect to the first axis.
