Abstract: A braking force distribution method and system for multiple marshalling train compartments are provided. The method includes: determining a current train compartment of multiple target marshalling train compartments, calculating current axel loads of axels of the current train compartment, and distributing braking forces for the axels of the current train compartment in a positive correlation manner based on the current axel loads of the axels.

A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.

The first valve closing position is different from the second valve closing position, such that wear caused by valve closing can be reduced.

Abstract: In some boost converter applications, an input voltage normally exceeds a regulated output voltage. The operation of the boost converter in this condition can be referred to as a pass-through operation. Using various techniques, the efficiency of a pass-through operation of a synchronous boost regulator circuit can be greatly improved. For example, a synchronous boost regulator circuit can include an input voltage VIN to output voltage VOUT voltage comparator that can accurately monitor the output voltage to detect the pass-through operation. In a pass-through operation, the high-side switch can be kept ON to maintain high efficiency, and the quiescent current of the regulator circuit can be minimized by setting portions of the control circuit into a sleep mode.

Abstract: During a load transient or load current step, an error amplifier of a regulator circuit can be temporarily pushed to saturation and a compensation capacitor can be discharged. The present inventor has recognized, among other things, that the transient response performance in such a case can suffer due to the slow rising rate of the error amplifier caused by the slow charging of the compensation capacitor. Using various techniques, a switching regulator circuit can include a proportional-integral (PI) compensation network clamp circuit that can provide a fast system transient response and a low quiescent current, which can reduce power consumption.

Abstract: The present disclosure describes a pressure support therapy device valve that enables a subject to safely supplement therapy pressure support with low flow oxygen while using a heated (or non-heated) tube. The valve conducts a pressurized flow of breathable gas and the low flow oxygen to the heated tube. The valve includes electrical components configured to pass power from the pressure support therapy device to the heated tube, and a plunger biased to close a flow path from the pressure support therapy device when a pressurized flow of breathable gas is not provided (or is below a predetermined pressure threshold). Closing the flow path stops oxygen gas from flowing back through the valve toward the pressurized gas source.
