The pitch angle detector: PADE
IEEE 1989 International Conference on Plasma Science, 1989The PADE analyzer can measure the pitch angle of electrons or ions with respect to the magnetic field in a magnetized plasma. This novel device is formed by two directional energy analyzers, mutually perpendicular to one another and each 4 mm in diameter.

Estimation of vehicle pitch angle
ATZ worldwide, 2006Vehicle pitch angle is one of the important state variables of vehicle dynamic control system. From this information one can draw conclusions concerning course of road and loading state. Due to economical reasons, the vehicle pitch angle is not measured in standard vehicles and therefore must be estimated.

Purely adiabatic motion, as described at length in Chapter I, characterizes the dynamical problem in which the phases φ1, φ2, and φ3 are cyclic coordinates. These are the phases canonically conjugate to the fundamental action integrals J1= 2πm0c|q|−1 M, J2=J, and J3=(q/c) Φ that identify the three adiabatic invariants M, J, and Φ of charged-particle ...

Identification of road gradient and vehicle pitch angle
Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005This report presents an approach for identifying the road uphill gradient and the vehicle pitch angle during straight forwards driving of a vehicle with the help of the vertical accelerometer, the longitudinal accelerometer and the wheel speed sensor signals. The derivation of the models and the used identification method are described.

Key Engineering Materials, 2010
In the paper, a static milling force model for variable pitch mills was built, and the milling forces were simulated. The resultant force and its frequency spectra of variable pitch mills were analyzed compared with that of uniform pitch mills. It is shown that the standard deviation (SD) of frequency spectra amplitudes for variable pitch mills is ...

Diverse images combination by pitch and roll angles
2014 3rd Mediterranean Conference on Embedded Computing (MECO), 2014Diverse images combination in aircraft onboard technical vision systems (TVS) issue is inaccurate determination of aircraft coordinates and TVS sensors positioning angles with incomplete synthesized images object structure. Existing algorithms cannot perform images combination in a reasonable time or cannot reach required accuracy.
