Abstract: The present disclosure is directed to a system having a first loading component and a second loading component for applying load to a device during a test of the device, the first loading component is configured to be moveable with respect to the second loading component. The system includes a seal member arranged between the first loading component and the second loading component, the seal member is adapted to engage the device diming testing so as to apply a load against the device during testing and provide sealing around a cavity positioned below the first loading component and above the device.

Abstract: A system is provided for improving performance of inertial sensing systems. The system uses dynamic stability compensation to adapt to the changing state of the inertial system such that the system remains ultra-responsive during dynamic events, while also exhibiting ultra stable output during subtle motions or rest conditions. The system uses a method that operates upon output data as it exits the component sensors but before it enters the sensor fusion that produces a final orientation. The method can be used with any sensor fusion algorithm to provide improved noise and stability performance in the output while having little to no impact upon responsiveness of that output during dynamic conditions.

Abstract: A system, a method, and a computer program product are provided. At predetermined times, a processing element processes a new vector represented by a last received magnetic measurement from a magnetometer and indicating a direction and a magnitude of a sensed magnetic field. When the new vector satisfies multiple criteria, the new vector is added to a determined vector set. The processing element processes multiple magnetometer measurements using a Monte Carlo best fit determination and modal partitioning to produce new calibration parameters that define a calibration sphere. The new calibration parameters are applied and stored in a memory element when at least a predetermined number of vectors are consecutively added to the determined one of the multiple vector sets.

Abstract: A system, a method and a computer program product are provided for local perturbation immunity in a vector-based sensing device. Measurement data from at least one vector-based sensing device is evaluated at a given time using a heuristic to identify an occurrence of a perturbing event, wherein the at least one vector-based sensing device includes either a magnetometer or an accelerometer, or both the magnetometer and the accelerometer. A time-shifting component is provided to reject the perturbing event for a duration of the perturbing event and use measurement data from a gyroscope to construct vector-based sensing device measurement data unaffected by the perturbing event.

Abstract: Systems and methods described herein relate to the correction of positional vector-valued sensors using a variety of calibration processes including fixed-angle calibration, known-angle calibration, ortho-calibration and 3-axis gimbal calibration further including various weighting schemes to provide fine-tuned functions or interpolated data which may be used for real-time sensor correction calculation or to populate a look-up table of corrected values.

Abstract: A collapsible overhead guard for use with an industrial vehicle or the like may be easily lowered so as to accommodate vehicle operation in areas where low overhead clearance is encountered. The guard includes forward and rear telescoping support members joined by a substantially rectangular roof member. The front telescoping support members are rigidly fixed to the roof member and to the vehicle and include bearing mounted rollers to facilitate relative movement. The rear telescoping support members are pivotally connected to the roof member and to the vehicle so that the generally horizontal orientation of the roof member is maintained. Locking means including retractable pins on each support member are provided for retaining the collapsible overhead guard in a plurality of positions.
