Abstract: The present invention is an apparatus and method for correcting errors generated by a laser with non-ideal tuning characteristics, the apparatus comprises a laser having non-ideal tuning characteristics. At least three interferometers are positioned in an operable relationship to the laser, wherein a sampling interferometer and at least one auxiliary interferometer correct for residual errors resulting from the laser; and wherein a measurement interferometer makes a measurement. A signal acquisition system is positioned in an operable relationship to each interferometer and a processor is positioned in an operable relationship to the signal acquisition system.

Abstract: A storage apparatus for storing an object, such as a bicycle, in an elevated storage position. The storage apparatus includes an elongated track mountable to a wall, and a support mechanism for receiving the bicycle. A mounting assembly mounts the support mechanism to the elongated track such that the support mechanism can move along the track between a loading position, wherein the bicycle can be loaded onto the support mechanism, and a storage position, wherein the bicycle on the support mechanism is elevated relative to the loading position. A drive assembly is operable for moving the support mechanism between the loading and storage positions. The drive assembly includes a drive mechanism for preventing movement of the support mechanism between the loading and storage positions upon operation of the drive assembly when the object on the support mechanism exceeds a maximum weight limit of the storage apparatus. The mounting assembly includes first and second resilient members.
