An ice skate chassis is configured so that a user can adjust the pitch of the skate chassis between a plurality of discrete pitch positions. The pitch is adjusted by locking the ice blade at a desired angle relative to a bladeholder of the chassis. The blade can be positively locked at a plurality of discrete, repeatable angle positions so that the angle will not slip or creep during skating.

An apparatus and method are provided for sealing an outer surface 170 of a shaft 175 to an inner surface 165 of a hub 160. The seal includes a magnet 155, with top and bottom pole pieces 260, 265, and a ferrofluid 270 magnetically held in a gap 275 between the pole pieces 260, 265, and the hub 160 or the shaft 175. The top pole piece 260 has a cross-section that is L-shaped, with a horizontal portion 260a parallel to the magnet 155 and a shorter vertical portion 260b facing the shaft 175. In one version, the vertical portion 260b or the portion of the shaft 175 facing it is contoured to provide a flux gradient that axially concentrates the ferrofluid 270 in the gap 275. In another aspect, a catcher 335 is provided to reduce loss of ferrofluid 270 when the ferrofluidic seal 185 used to form an outside seal. In yet another aspect, a stationary ferrofluidic seal 345 is provided for sealing a stationary shaft 350 to a rotating hub 355.

The swapping function of input values to output values is performed through a pseudo content addressable memory which provides output values corresponding to a number E of n-bit input values, with E=2p−1. The pseudo content addressable memory is made of a plurality of cascaded random address memories 20 having at least a 2d addressing capability, with d higher than p. A control logic circuit is provided to store into each random access memory p-bits pointers, with each pointer being different from the others and randomly assigned to an input value. In order to find an output value corresponding to an input value, the control logic circuit sequentially address and reads the cascaded random access memories, the first memory being addressed with a part including a number n1 of bits of the input value, and each one of the next memories being addressed with the pointer read from the preceding memory concatenated with another part ni of bits of the input value, with ni equal to or lower than n−n1. The output value is found as a result of the addressing of the last memory.
