A filter for post-processing digital images and videos, having an edge mapper, a pixel sorter, and an adaptive filter that simultaneously performs de-ringing and edge sharpening. The physical assistance device has a frame including a pair of spaced front legs and a pair of spaced rear legs and defining a front and a rear and an interior area in which a user may stand when walking when facing the front of the physical assistance device. The triaxial magnetic driving portion includes a pair of focusingtilting driving magnets, a pair of tracking driving magnets, focusing coils, a pair of tilt coils, and a pair of tracking coils. In some cases, the monitoring and analysis begins with selection of a group of processes to monitor, while in other cases it begins with monitoring of network andor user update activities in order to narrow the group of suspect processes. Different embodiments have different valve component arrangements for influencing the reaction time of the suspension andor for adapting the circuitry for use with single-acting, double-acting or telescopic boom cylinders.
