Abstract: A bicycle frame part having a disproportionally enlarged end section and a method for making the same. The tube may be used as a bicycle frame part, and it may include a first section having a thickness, a second section configured to be forged from a first shape having a thickness that is different from the thickness of the first section to a second shape having a thickness that is less than the thickness of the first shape. The second shape of the second section may be proportionally enlarged relative to the first shape of the second section.

Abstract: A device is described for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, in which a vehicle dynamics controller is stored, at least one final control element, and a sensor system for measuring different driving condition variables, and including a rear-wheel steering system having a control unit and a final control element. The electronic stability program may be integrated into a control unit if the electronic stability program algorithm includes a distributor unit which, from a regulator output variable, generates both a setpoint requirement for the final control element of the vehicle dynamics control system and also a setpoint requirement for the final control element of the rear-wheel steering system.

Abstract: A transformer level driving circuit mainly aims to drive a medium voltage system. It includes a control unit to generate a resonant frequency and output phase signal waveforms, and a medium voltage driving circuit which includes a floating level unit and a driving unit which receives a medium voltage electric input. The driving unit actuates opening and closing at different time to enable the floating level unit to output a voltage floating level thereby to drive a ceramic transformer to control the medium voltage system through a low voltage level.

Abstract: A ceramic transformer level driving circuit mainly aims to transform a low voltage signal to another low voltage signal through an amplified signal to drive a medium voltage system. It includes a control unit to generate a resonant frequency and output phase signal waveforms, a waveform transformation unit to provide phase signals and perform waveform phase transformation for the phase signal waveforms, and a medium voltage driving circuit which includes a floating level unit and a driving unit which receives a medium voltage electric input. The driving unit actuates opening and closing at different time to enable the floating level unit to output a voltage floating level thereby to drive a ceramic transformer to control the medium voltage system through a low voltage level.
