The drive unit, the drive belt, and the fastening plate can be placed directly on a floor in such a way that the drive body moves the drive belt and the fastening plate along the floor. The coupling mechanism can be controlled in such a way that the test object is coupled to the fastening plate and can be actively decoupled from the fastening plate from a predetermined operating paint before a collision between the collision body and the test object such that the test object is decoupled from the fastening plate during the collision between the collision body and the test object. | 02-25-2016 |
20160131552 | SHOCK SENSOR WITH LATCH MECHANISM AND METHOD OF SHOCK DETECTION - A micromechanical shock sensor includes a proof mass coupled to a surface of a substrate and a projection element extending laterally from the proof mass. The shock sensor further includes a latch mechanism and a retention anchor. The latch mechanism has a latch spring attached to the surface and a latch tip extending from a movable end of the latch spring. The retention anchor is attached to the surface and is located proximate the latch tip. The proof mass is configured for planar movement relative to the substrate when the proof mass is subjected to a force of at least a threshold magnitude. Movement of the proof mass in response to the force causes the latch tip to become retained between the projection element and the retention anchor to place the shock sensor in a latched state. The latched state may be detected by optical inspection, probe, or external readout. | 05-12-2016 |
20160131556 | APPARATUS AND METHOD FOR TESTING AN AIRBAG CONTROL UNIT - An apparatus for testing a vehicle airbag ECU is provided. The apparatus includes a support plate having a first surface for mounting the airbag ECU and a wheel rotatable about a rotational axis. An input chute is positioned above the wheel and configured to direct an aggregate to the wheel. A motor is connected to a power supply and drivingly connected to the wheel. A controller is programmed to operate the motor and to selectively vary a rotational speed of the motor and the wheel. The wheel is configured to project the aggregate to impact a second surface of the support plate that is opposite the first surface. | 05-12-2016 |
