Patent ID: 8032279

Claim:
A wheel alignment head configured to obtain measurements usable in calculating wheel alignment parameters of a vehicle, wherein the alignment head is operable in a first operation mode and in a second operation mode consuming less power than the first operation mode, and responsive to an occurrence of at least one preset event, the wheel alignment head switches from the first operation mode to the second operation mode, comprising one or more functional modules, each of which is configured to perform a designated function; and a data processor, coupled to the functional modules, for processing data, wherein when entering the second operation mode, the data processor issues a command to selectively adjust an operation of the alignment head in response to the occurrence of the at least one preset event, and wherein the data processor, upon execution of pre-stored machine-readable instructions, controls the alignment head to enter the second operation mode by selectively performing one or more prescribed steps corresponding to a respective occurred preset event.
