Patent ID: 7123134

Claim:
A wheel strobing device comprising: a tachometer unit to couple to a rotational reference frame of a wheel to determine a rotational frequency of the wheel; a strobing element to couple to the rotational reference frame of the wheel and the tachometer, the strobing element capable of operating in a first mode and a second mode, wherein the frequency of the strobing element is related to the rotational frequency of the wheel and to a number of degrees of symmetry of a wheel feature when operating in the first mode and the frequency of the strobing element is independent of the rotational frequency of the wheel when operating in the second mode; a set of one or more lighting elements to couple to the rotational reference frame of the wheel and the strobing element, the set to operate under the control of the strobing element; and a comparator to compare the frequency of the strobing element with a threshold frequency such that if the frequency of the strobing element is higher than the threshold frequency, the wheel strobing device operates in the first mode and if the frequency of the strobing element is lower than the threshold frequency, the wheel strobing device operates in the second mode.
