Abstract: Systems and methods of the present disclosure include the use of a tracer in agricultural spray solutions, and preferably a metal tracer, to determine if off-target drift of an active ingredient (AI) is based on drift caused during application or volatility of Al after application.

Abstract: A system including a broadband switch includes a controller which coordinates video call set-up and a switch for connecting various phone lines together through diplexers. The system permits video telephone conferencing and other video related applications to be performed over ordinary telephone wires. Two diplexer/modems are typically provided for each user: one at the user's telephone jack and another at the central PBX location for that user's telephone line. The PBX connections can usually be made in a central wiring closet. A video server can also be provided which retrieves video images from disk to provide on demand to users. the existing PBX handles the switching of normal telephone audio signals, and a broadband data switch handles the switching of broadband signals over the same telephone wires that the PBX uses. The broadband switch essentially “piggybacks” off the PBX system and avoids interference with telephone signals through the use of diplexers.

Abstract: A method and apparatus is provided for interfacing a plurality of ISDN lines from a telephone company central office to equipment which transmits video data, such as videoconferencing equipment. A single telephone wiring jack is directly coupled to two, three, or four ISDN lines without conversion to S/T channels. The single telephone wiring jack is coupled to an interfacing device which converts each ISDN line format into a format compatible with the videoconferencing equipment, such as the Multi-Vendor Interface Protocol format. Rather than using conventional wiring pin-outs for the single telephone wiring jack, all pins of the jack may be allocated to carrying ISDN data. The inventive method and apparatus avoids the expense of various conversion devices and wiring of separate telephone jacks, and permits as many ISDN lines to be allocated as are needed to support a desired bandwidth.
