Abstract: The invention relates to zeolite particles which are at least partially coated with a coating that is capable of delaying the release of heat from the zeolite particles upon contact with water over time. The coating effectively at least partially blocks the pore structure of the zeolite particle from contact with water, thereby delaying contact between water and the zeolite, and prolonging the warming effect caused by such contact.

Abstract: A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector, an initial processing module, and a spectra processing module. The initial processing module is provided for receiving, sampling, and processing ion detection signals received from the ion detector, and for supplying processed signals to the spectra processing module.

The number of adjacent samples to combine into bins may vary as a function of: (1) the time of arrival at the ion detector corresponding to that sample; (2) the mass corresponding to that sample; (3) the resolution corresponding to that sample; and/or (4) an operational mode of the spectrometer. The spectra processing module receives the processed signals and generates spectra.

Abstract: Several embodiments of a rotational position sensor having a variable coupling transformer are disclosed. Each sensor employs at least one magnetically permeable transformer core and a primary and secondary coil. The primary coil in coupled to a time varying electrical signal and is mechanically coupled through a transmission to a rotatable shaft whose position is to be measured. As the shaft is rotationally displaced, the primary coil changes orientation thereby changing an output signal induced in the secondary. A detector is coupled to the secondary coil to monitor the output signal and correlate the signal to the shaft's rotational displacement.

Abstract: A multi-turn rotational position sensor. A spirally wound conductor has an inner end coupled to a rotatable shall through a transmission. As the shaft rotates, the spirally wound conductor changes shape. The spirally wound conductor is inductively coupled to a transfcrmer secondary and the transformer coupling between the spirally wound conductor changes as the shaft rotates. An output from the transformer secondary is used to determine the shaft's rotational position.
