Patent CA-2190203-C (CA)
Inventor: MASON PHILIP L
IPC: G01L3/12
Filed: 1996-11-13
Granted: 2005-02-08
Abstract: This invention discloses an optical and computation system that enables the magnitude of the retardation, or the birefringence, in a birefringent material to be measured. This is achieved by consideration of the spectral interference pattern generated by combining quadrature axes of polarized light that have passed through the material, however, unlike other approaches, this invention removes the spectral intensity variations of the light source and the spectral attenuation variations of the optical system before analyzing the resultant spectral interference pattern. Since the spectral interference pattern is unique for each retardation or birefringence value, this invention provides an absolute measure of these quantities. Additionally this invention permits the full range of retardations or equivalent birefringence values to be measured, from zero retardation to any (large) value that does not create interference modulations, the frequency of which exceed the Shannon-Kotelnikov criteria for the wavelength or spectral sampling implemented. Further, in the second main embodiment of this invention, the dependence on stored light source spectral intensities and stored optical light path attenuations is removed, with the system being independent of any time dependent variations in intensity and/or attenuations and additionally, being independent of any axial alignment or setup requirements.

Granted: 2003-01-21
Abstract: An axle tilt control apparatus for forklifts is disclosed.  The forklift includes a rear axle pivotally supported by a body frame and a rear axle rigidly fixed to the body frame.  A mast is supported at the front portion of the body frame to tilt forward and backward.  Forks are supported by the mast to be lifted and lowered.  The center of gravity of the forklift in the fore-and-aft direction approaches the front axle as the mast is tilted forward. Pivoting of the rear axle is restricted by the hydraulic cylinder when the height of the forks is higher than a predetermined height determination value and the weight of a load on the forks is heavier than a predetermined weight determination value to improve the vehicle's stability.  The weight determination value increases as the mast is tilted forward.  When a load on the forks is being unloaded, tilting of the rear axle is permitted regardless of the height of the forks and the weight of the load on the forks. Therefore, the rear axle is not unnecessarily locked.
