Publication number: 20240101172Abstract: System and methods are disclosed to promote safe shoving movements of a train based on train position localization without human-based track operations monitoring. Train position detectors deployed at the end of a track, in parallel to the track, between the rails of the track, or a combination thereof, localize an end-of-train during shoving movements. Each train position detector transmits an early warning alert to an onboard alert device and a handheld alert device for indicating the end of the train is about to enter a pre-configured prohibited zone. The locomotive operator receives the alert on the onboard alert device while workers in the railyard receive the alert on the handheld alert devices. Both onboard and handheld alert devices are capable of generating audio, visual, haptic, or a combination of these warning alerts for the locomotive operator and the workers in the railyard.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Inventors: Muhammad Mohsin Naseer, Mukhtiar Ahmad, Haider Ali, Brent Fransen, Joseph Montgomery, Kevin Pilger, Randy Skarlupka, Kevin Smith, Richard Spitzer

Patent number: 11921229Abstract: An apparatus, including processing unit (PU) cores and computer readable storage devices storing machine instructions for determining a distance between a target object and a radar sensor circuit. The PU cores receive a beat signal generated by the radar sensor circuit and compensate for a phase difference between the received beat signal and a reconstruction of the received beat signal to obtain a phase compensated beat signal. The phase compensated beat signal is then filtered to remove spurious reflections by demodulating the phase compensated beat signal using an estimated frequency of the phase compensated beat signal. The PU cores then apply a low pass filter to the demodulated phase compensated beat signal, resulting in a modified beat signal. The PU cores then determine the distance between the target object and the radar sensor circuit using the modified beat signal.Type: GrantFiled: September 20, 2021Date of Patent: March 5, 2024Assignee: Texas Instruments IncorporatedInventors: Muhammad Zubair Ikram, Adeel Ahmad, Dan Wang, Murtaza Ali
