Abstract: A method and apparatus for measuring the percentage of fat trim and of saleable yield of cattle and their carcasses including providing power to a transmitting circuit to transmit a signal to electrodes resulting in a potential difference across the electrodes causing a flow of current between the electrodes reflecting the impedance encountered and sending a signal reflecting such information to receiving circuits which pass that data to processing circuits which process that data with other external inputs to produce an output display reflecting an indication of the state of hydration of the animal, comprising: means for providing a voltage difference across two or more penetrating electrodes; means for maintaining said electrodes in a fixed spatial relation and in good electrical contact with the tissue on which said measurements are to be made; means for measuring the impedance in the region of or between the electrodes; means for transmitting the measured data to processing circuits which process that

Abstract: An electrode holder comprising a deck member with handle supporting a pair of penetrating electrodes to which a hypodermic syringe or needles may be connected and which may act as electrodes in a BIA system and/or in connection with making other electrical measurements.

Abstract: A method and apparatus for measuring and analyzing the state of hydration of a horse, camel or other hairy animal including providing power to a transmitting circuit to transmit a signal to electrodes resulting in a potential difference across the electrodes causing a flow of current between the electrodes reflecting the impedance encountered and sending a signal reflecting such information to receiving circuits which pass that data to processing circuits which process that data with other external inputs to produce an output display reflecting an indication of the state of hydration of the animal, comprising: means for providing a voltage difference across two or more electrodes; means for maintaining said electrodes in a fixed spatial relation and in good electrical contact with the skin of the animal without penetrating the skin of the animal on which said measurements are to be made; means for measuring the impedance of said animal in the region of or between the electrodes; means for transmitting the

Abstract: An electrode holder comprising a pair of electrodes connected by a flexible, insulating rod which controls the position of the electrodes with respect to each other and the topographic surfaces of the body or body part of the animal.

Abstract: A crop cleaner comprising a generally parallel array of first and second rollers each first roller being scrolled and each second roller generally unscrolled, the first rollers alternating with second rollers with pairs of adjacent rollers being carried on frames with each frame being displaceable relative to an adjacent frame and a drive for independently rotating each pair of rollers.
