Abstract: An electronic pedal apparatus is configured so that a driver may operate a pedal 200 with a small effort, the electronic pedal apparatus may operate by fine displacement during the operation of the pedals, the pedals apparatus may allow the driver to clearly recognize an operating situation of the pedals by use of a magnetic force (repulsive force) having a quadratic function graph, and a compact mechanism having a foldable function may be implemented by use of an electromagnet that changes in polarity.

Abstract: An embodiment fuel cell including a high temperature polymer electrolyte membrane includes an electrolyte membrane including a phosphoric acid-doped polymer of intrinsic microporosity, a cathode disposed on a first surface of the electrolyte membrane, and an anode disposed on a second surface of the electrolyte membrane, the second surface opposite the first surface.

Abstract: An electronic pedal apparatus includes a pad that rectilinearly moves and rotates along a pad guide while being kept in line contact with the pad guide including a shape of an arc when a driver operates the pad, an acceleration signal or a braking signal for a vehicle is generated by operation of the single pad, and a movement direction of the pad at the time of generating the acceleration signal is different from a movement direction of the pad at the time of generating the braking signal.

Abstract: An embodiment electronic pedal apparatus includes a pedal housing and an accelerator pedal assembly and a brake pedal assembly coupled to the pedal housing and configured to move along different movement trajectories when the accelerator pedal assembly and the brake pedal assembly are operated. In an embodiment, the accelerator pedal assembly is compressed and moved upward when the accelerator pedal assembly is operated, and the brake pedal assembly is compressed and moved downward when the brake pedal assembly is operated.

Abstract: A knob assembly with a display that displays information such as power level and a timer time, and a cooking apparatus including a knob assembly are provided. The knob assembly may include a knob coupled to an adjustment shaft configured to adjust power level and a knob ring configured to surround a periphery of the knob, configured to be rotatable independent of the knob, and provided with a display. The display may be provided at the knob ring, and information may be displayed on the display so that a user may easily manipulate the knob assembly.
