Abstract: A roller clutch mechanism of a reversible ratchet tool is configured to include a biasing and reversing mechanism for biasing rollers in the roller clutch mechanism. A cage member of the roller clutch mechanism locates rollers in either a clockwise or counterclockwise position based on a selective position of the reverser mechanism. The reverser mechanism applies a constant bias to the cage member so that the rollers are constantly biased and quickly engage between the ratchet body and the drive head. The constant bias applied to the cage member reduces the ratcheting angle for improved performance of the reversible ratchet tool.

Abstract: An alignment measurement system for a vehicle includes an alignment sensing system and a suspension relaxing system. The suspension relaxing system is configured to receive at least one wheel of the vehicle and is operable between a plurality of states. The alignment sensing system is operatively connected to the suspension relaxing system to select a state of the suspension relaxing system. In a first state, the suspension relaxing system maintains the wheel of the vehicle stationary when the wheel is received by the suspension relaxing system, and in a second state, the suspension relaxing system allows the wheel to turn and/or translate. Prior to performing a measurement on the alignment of the vehicle, the alignment sensing system directs the suspension relaxing system to be operated in the second state.
