摘要： A method and apparatus for bearing thrust monitoring allows measurable detection of tilt of a support bearing (52 or 56) for a roller (34 or 36) which rotatably supports a rotating body (22). A tilt meter (75 or 77) adapted to measurably detect a tilt of the support bearing is coupled to the support bearing (52 or 56), where the tilt is defined as an angular difference in bearing orientation between a first bearing position and a second subsequent bearing position that is cause by an axial thrust on the rotary body (22). Once tilt is detected, the bearing orientation of the support bearing (52 or 56) can be adjusted to return the support bearing (52 or 56) to substantially the first bearing position.

摘要： A representative positron emission tomography (PET) calibration system includes a PET scanner having a ring detector, a phantom that is placed at approximately the center of the ring detector, and a time alignment calibration manager that is coupled to the PET scanner. The time alignment calibration manager detects coincidence events from the phantom, calculates position of time of flight events from the ring detector based on the detected coincidence events, and calculates time offsets for the ring detector using a mean value calculation based on the calculated position of the time of flight events.

摘要： Web measurement system monitors properties of a web during manufacture without chopping measuring radiation during web measurement. A single chop is performed at each sheet edge or every nth sheet edge to measure edge temperature and edge thermal radiation for correction for Planckian radiation. Correction factors, including Planckian radiation correction factors, are derived for each point in a web profile. The measuring system also enables derivation of correction factors during operation in a single point and similar machine operating modes.
