Abstract: A system and method for monitoring operation of a press assembly includes establishing a baseline vibration level for a first location on the press assembly. The baseline vibration level defines a boundary for vibrations beyond which one or more press elements have a reduced life expectancy. Vibrations are measured at the first location and also at a second location during operation of the press. The vibrations measured at the first location are correlated with the vibrations measured at the second location, and a relationship between the vibrations at the first and second locations is established. Vibrations measured at the second location can then be adjusted and compared to the baseline vibration level to determine if adjustments to the press operation need to be made, or if certain press elements will need to be replaced prior to their expected life span.

Abstract: To create a broad band spectrometer, a plurality of individual antenna based bolometers are fabricated on the surface of a single spectrometer chip, each bolometer having an individual antenna which is sized differently from all others, thus being responsive to a generally unique frequency of radiation. Each antenna is coupled to a related transistor, which is easily formed using CMOS technology. The antennas are connected to opposite sides of a transistor gate, thus creating a termination resistor for the particular antenna. Multiple outputs from the various antennas are then coupled, thus providing responsiveness to electromagnetic radiation of a very broad spectrum.

With the predicted value as the reference, a transmission frequency of an RF magnetic field irradiated in a signal suppression pulse sequence, a transmission frequency of an RF magnetic field for excitation and inversion and a received frequency at the detection of a magnetic resonance signal in a sequence of the MRS measurement are respectively set. A high-precision spectrum measurement is hence enabled.
