Abstract: A vehicle includes wheels, force sensors adapted for a vertical force and lateral force of each wheel, an onboard device, and a controller. The controller calculates vehicle values using the vertical force and lateral force, compares the values to a corresponding threshold, and automatically deploys the device when each element value does not exceed a corresponding threshold. A method for determining when to deploy an airbag includes measuring a vertical and lateral force at each wheel, and measuring a yaw rate and roll angle. A lateral velocity is calculated using the lateral force, and a lift of each wheel is calculated using the vertical force. The roll angle, roll rate, and stopping time are processed to generate a point on a 3D rollover plane. A rollover energy rate is calculated, and the airbag deploys when the point, rollover energy rate, and lift do not exceed a threshold.

Abstract: An apparatus for automatic loading or unloading printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus employs an elastic jig carrier into which the PCBs are loaded. The jig carrier includes movable clamps for fixing the PCBs by elastic force. A jig opener of the apparatus applies opening force, in the reverse direction of the elastic force, to the movable clamps so that the PCBs can be loaded into or unloaded from the jig carrier by a picker. The jig carrier is transferred along a conveyor belt, while the PCBs are supplied from a PCB stage such as a tray to the jig carrier. The apparatus may further comprise a gripper and a rotator. The gripper grips the upright PCBs and the rotator rotates them to be horizontal, so that the picker can pick up the horizontal PCBs. The apparatus may also comprise an aligner for exact alignment of the PCBs in the jig carrier. A method for loading or unloading the PCBs into or from the jig carrier is also disclosed in connection with the apparatus.

Abstract: An apparatus for carrying plural printed circuit boards (PCBs) for semiconductor modules is disclosed. The apparatus comprises a main frame which is formed with an inside space for the PCBs. The main frame includes receivers for supporting one shorter edge of the PCBs. A clamp frame joined to the main frame includes a support plate for the other shorter edge of the PCBs. Movable clamps are elastically connected to the clamp frame so as to push the PCBs by elastic force when the PCBs are loaded into the apparatus. A adjustable mounting such as a slot or holes is provided in the main frame for fasteners joining two frames each other. Therefore, the apparatus can carry the PCBs of different size. The elastic connection between the clamp and the clamp frame is preferably made by slide bars and elastic members. Clamp holes, sub-walls, partition walls, hollow corners, and so forth may be preferably provided for the apparatus.
