Abstract: 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.

Abstract: The leverage ratio of the rear brake pedal of the Yamaha Tenere 700 (XTZ690) motorcycle is changed to allow the rear brake to be activated properly with substantially less pedal travel. This leads to firmer pedal feel, faster braking and less ankle deflection to properly apply the brake. The pivot point of the brake pedal is fixed on the bike's frame so it cannot be moved so the short side of a new pedal has been lengthened rearward creating more upward motion to the master cylinder with less movement of the long side of the lever. The master cylinder's pushrod is then out of alignment with the master cylinder due to the lengthened brake pedal. A newly designed offset clevis is added to realign the pushrod with the master cylinder.
