A vehicle safety system target includes a first platform disposed on a mobile chassis, a frame assembly, a first securing member, a second platform, and a mounting member. The frame assembly is at least partially disposed about the mobile chassis and includes a first frame member and a second frame member. The first frame member is disposed on the first platform. The second frame member is disposed on the first platform. The first securing member is configured to couple an object to the first platform. The second platform is spaced apart from the first platform. The mounting member is disposed on the second platform.

A method and system for evaluating and loading vehicles (e.g., aerial vehicles and other vehicles) are described herein. The vehicles are moved by a conveyance device. It may be determined whether a vehicle passes at least one of a structural integrity test or a functionality test. The vehicle may be removed from the conveyance device, e.g., by a robotic manipulator, in the event the vehicle fails at least one of the structural integrity test or the functionality test.

A computer for a vehicle is programmed to receive fuel level data over a period of time during a refueling operation. Based on the fuel level data, the computer determines that fuel flow rate during one portion of the refueling operation is materially reduced relative to other portions of the refueling operation. The computer is programmed to output a failure mode based on the determination.

A balance has a balance centerline and an axial force measurement section having a longitudinal slot partially dividing the axial force measurement section into a first part and a second part longitudinally overlapping each other and interconnected by corner flexure groups. The axial force measurement section has an axial force measurement beam located approximately midway between the corner flexure groups. The axial force measurement beam has strain gages for determining axial force on the model. Each corner flexure group includes flexures each having a first flexure root and a second flexure root respectively joined to the first part and the second part. The flexures each have a flexure midpoint between the first and second flexure roots, and a flexure thickness that is tapered along the flexure length from each of the first and second flexure roots to a reduced thickness proximate the flexure midpoint.

The purpose of the present invention is to provide a determining device and a determining method to determine whether an inspected jet nozzle is defective by inspecting the jet nozzle for injecting a jet stream with long ground penetrating distance at a stage before installing in a construction site where a large diameter jet grouting method is used. To achieve this purpose, with this invention, in which a nozzle to be inspected is mounted onto an outlet port, a jet stream is ejected from a jet stream generating device, and measurement data measured by a pressure sensing unit when the jet stream impacts the pressure sensing unit is processed with a controlling device (for example, a computer), a nozzle to be inspected is determined to be a non-defective product if a first ratio is no less than a first prescribed value, a second ratio is no less than a second prescribed value, and a third ratio is no less than a third prescribed value.

A method and apparatus for determining failure diagnosis of drive systems of rotorcrafts through measuring the spectral characteristics of rotational oscillations and torsional oscillations and steady windup of a drive shaft. Mechanical anomalies of the drive system will alter the spectral characteristics of rotational oscillations and torsional oscillations and steady windup as detected by a pair of variable reluctance sensors in conjunction with a radial grating mounted on the drive shaft.
