A system and process for aligning wheels of a three-wheel cycle include mounting targets to two wheels on an axle of the three-wheel cycle and positioning an alignment device relative to a single wheel of the three-wheel cycle to create a virtual axle and assess thrust angle. Once targets are in place, thrust angle is reduced to zero, and camber, caster, and toe measurements are taken and adjusted as needed to achieve three-wheel alignment.

A distance-measuring apparatus and a distance-measuring method. The distance-measuring apparatus and the distance-measuring method include emitting pulsed light, receiving and photoelectrically converting the pulsed light emitted and reflected by an object into a plurality of electrical signals, sorting the electrical signals into a plurality of phase signals, storing data including the phase signals or a value that is based on the phase signals, determining whether or not a dynamic change is present in the object, based on the data of a current frame and at least one past frame, and calculating distance to the object using the data, according to a result of determination made by the determining. When determined that the dynamic change is not present, moving average calculations are performed on the data of at least two of the current frame and a plurality of frames including the at least one past frame.
