A device, that includes nonvolatile memory, a peripheral antenna, and a peripheral radio frequency receiver, is configured to receive a peripheral RF signal containing programming and to write the programming to the nonvolatile memory. The liquid crystal display device includes pixels configured to be connected to scan lines and data lines, data pads electrically connected to the data lines, a data integrated circuit supplying data signals to the data lines through the data pads, first data transistors coupled to the data pads, and second data transistors coupled to the data lines. In another embodiment, a differential signal is substantially cancelled by a pseudo differential arrangement including two independent input resistance paths each in parallel with a corresponding negative resistance path, wherein the resistance paths substantially match the input resistance paths. A hydraulic cylinder, working against a spring defined by an accumulator, is coupled to a downstream end of the channel wall and resists movement of the channel wall away from the feed rotor, but yields under a preselected crop load. The number of injection cycles can be two or more, and the penetration depth for a given injection cycle can be controlled.
