The bent covering panel includes a major portion and a minor portion, with an angle between the major and minor portions. The major portion is pivotally connected to one of the concealable panels. The minor portion is pivotally connected to the flat covering panel. The flat covering panel is further pivotally connected to the other concealable panel. The minor portion provides a gap between the major portion and the flat covering panel to receive the first and second concealable panels when the collapsible stoking apparatus is in a collapsed position.

Abstract: A mixed-voltage I/O buffer includes an input buffer circuit. The input buffer circuit includes a first inverter, a first voltage level limiting circuit, a first voltage level pull-up circuit, an input stage circuit, and a logic calibration circuit. The first inverter inverts an input signal to generate a first control signal. The first voltage level limiting circuit limits voltage level of an external signal to generate the input signal transmitted to the first inverter to prevent electrical overstress of the first inverter. The first voltage level pull-up circuit is controlled by the first control signal to pull up voltage level of the input signal inputted into the first inverter. The input stage circuit receives the first control signal to generate corresponding digital signals inputted into a core circuit. The logic calibration circuit calibrates voltage level of the first control signal when the first inverter mis-operates due to the input signal having a low voltage level.
