Abstract: A quadrature clock generator that takes advantage of the inherently low delay of a shunt-series inductively peaked clock buffer to generate quadrature clocks with the high jitter performance using just one additional stage in Q path compared to I path. The generator includes a delay cell that uses shunt-series peaking and uses a resistive DAC in series with the shunt inductor to provide a large delay range with good jitter characteristics. The resistive DAC can be placed near a real or a virtual ground to minimize capacitive loading on the signal path. This delay cell can provide greater than 2× delay tuning range and is suitable for clocks at high frequencies. This delay cell can also be used as a ring oscillator with large frequency tuning range. A low voltage differential signaling termination switch control that uses feed forward mechanism to control termination impedance of device in a receiver.

Abstract: A system for controlling the residual moisture in pre-cured binder coated glass fibers. The moisture of the binder coated glass fibers is measured after the process water is extracted in a collection box. Based on the level of moisture found in the coated glass fibers, adjustments are made to the process upstream of the moisture measurements. The adjustments include, but are not limited to, adjusting the amount of water used to make the binder composition; adjusting the amount of heat applied to the binder composition as it is applied to the glass fibers and adjusting the vacuum conditions used to extract the process water from the binder coated glass fibers. Control of the residual moisture in the precured binder coated glass fibers helps ensure proper curing of the binder during the subsequent curing step.

Abstract: A method of measuring the extent of cure of a binder in a fibrous product is provided. The method comprises (a) providing a sample of a fibrous product, the fibrous product comprising fibers and a binder, (b) subjecting the sample to infrared spectroscopy to generate a spectral analysis, and (c) determining a binder cure ratio of the binder in the sample using the spectral analysis. The binder has carboxylic acid groups and alcohol groups that crosslink to form ester groups as the binder cures, and the binder cure ratio comprises a ratio between infrared absorption corresponding to a bond of the carboxylic acid groups in the binder and infrared absorption corresponding to a bond of the ester groups in the binder.

Abstract: An electromagnetically operated engine cooling fan drive assembly is disclosed having a configuration particularly suited for retrofit applications, including a central shaft adapted to be mounted to an existing fan drive flange to be driven thereby. The fan is mounted on a fan hub member rotatably mounted on the central shaft, with a temperature responsive electromagnetic clutch arrangement controlling drive to the fan hub which arrangement includes an inner body keyed to the central shaft, an armature connected by spring connection to the fan hub, and a fixed electromagnetic coil energized by a temperature switch at high engine temperatures and adapted to urge the armature into clutching engagement with the inner body and cause the fan to be rotated.
