Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.

Abstract: Methods for converting mixtures of anthocyanins occurring in fruit or vegetable juice or extract into particular anthocyanin molecules having desirable colorant properties are provided herein. The method of the present disclosure can be employed to increase the amount of particular anthocyanin molecules, while lowering the total number of anthocyanin molecules present in the natural juice and/or extract. The disclosure is also directed to anthocyanin molecules prepared by the methods of present disclosure and to enzymes capable of catalyzing reactions that provide such effects.

Abstract: The present technology provides solutions that enable accurate measuring of frequency response on a network (e.g., cable network, fiber optic network) through frequency sweep testing. In various embodiments, the present technology provides a remote transmitter test unit that can be physically deployed at various points in a network. The present technology provides for on demand sweep testing. A remote transmitter test unit or headend test unit can periodically transmit a query message and, based on a response to the query message, can initiate a sweep test. The present technology provides for automatic generation of a sweep profile for a sweep test. Based on an analysis of a frequency spectrum on a network, the sweep profile provides parameters for conducting a sweep test. The present technology provides for Orthogonal Frequency-Division Multiplexing (OFDM) table generation and OFDM sweep testing.

Abstract: An integral multiple transmission line interface comprises a panel having opposite side portions defining, facility connection and subscriber connection regions having, respectively, a facility cable connector and subscriber cable terminals. A plurality of spaced modular jacks are arrayed longitudinally along the facility connection region of the panel, and a plurality of removably attached subscriber wiring bridges extend between the jacks and subscriber cable terminals. Interconnection between the subscriber wiring bridges and the facility cable connector is made through a printed circuit board within the panel. A pivotally mounted, removable cover protects the subscriber wiring terminals from human contact, and interlocking ears and collars formed on the panel enable the terminal devices to be stacked end to end.
