Abstract: Disclosed herein is a skate spinner including a platform configured of a flat board having a user's foot placed thereon, and a support unit corresponding to a lower part of the platform contacting a ground surface and having a curved protruded shape configuring a curved surface starting from a front end to a rear end, wherein the support unit is configured to have a series of plates each having a thickness equal to at least a thickness of an ice-skate blade and being aligned along a left-to-right direction at a predetermined distance, wherein, when observing a cross-section of the skate spinner taken along a direction being perpendicular to a front-to-rear longitudinal direction of the skate spinner, a height of each plate becomes higher starting from the plates positioned at both side ends of the skate spinner towards the plate positioned at a center of the skate spinner, and wherein an overall bottom surface of the plates contacting the ground surface configure a spherical surface outline. As described above, the skate spinner may allow a user to embody spin movements, which correspond to the same movements performed on ice, even on generally flat ground surfaces outside of the ice, when practicing for the spin movements using the skate spinner, wherein the skate spinner includes a support unit contacting the ground surface and having an overall spherical surface outline, and may allow the user to naturally tilt sideways (i.e., from left to right, and vice versa) in accordance with a shift (or change) in a center of gravity (or weight) according to front-to-back movements of the user's body as well as a shift in the center of gravity according to left-to-right movements of the user's body.

Abstract: A level shifter capable of high speed operation and a high-speed level shifting method. The level shifter includes a pull-down switching unit configured to selectively connect a first node and a second node with a first power supply (ground) voltage in response to a first switching signal and a (complementary) second switching signal, a pull-up switching unit connected between the first node and the second node and configured to connect the first node with a second power supply voltage in response to the voltage level of the second node and to connect the second node with the second power supply voltage in response to the voltage level of the first node, and a internodal switch configured to selectively connect the first node with the second node in response to a control signal. Due to the switching operation and resistance of the internodal switch, the level shifter can reduce power consumption and perform high speed level-shifting operation.
