This method and apparatus is directed to measuring flow velocity of a flowing solid or fluid in a pipe. In the preferred and illustrated embodiment, a single magnet is utilized to impress a magnetic field on the flow, the field having a gradient. A concentrically arranged detection coil is positioned in the field and is connected with a nuclear magnetic resonance (NMR) or electron magnetic resonance (EMR) detection apparatus. A segment of the material moves through the magnetic field. The frequency of a the magnetic resonance signal emitted by the nuclei or electron changes proportionate to field intensity. In a fixed gradient, the time rate of change of the emitted NMR or EMR frequency signal is a linear function of flow velocity. This apparatus provides a measure of flow velocity by interrogating with pulses thereby obtaining a frequency dependent signal. The approach has the advantage of utilization of a single coil and yields measurements which are independent of density or filling factor and also independent of elemental couplings identified as T. sub. 1 and T. sub. 2.

A method and apparatus are set forth for measuring flow velocity of an element of interest in a compound within a pipe. In the preferred and illustrated embodiment, a static magnetic field is imposed on the flowing material of interest. Preferably, a uniform field of finite width is imposed. There is a first coil around the path for imposing an RF magnetic field at right angles to the static magnetic field. There is a relationship between the flowing material including the element, frequency of the RF field and static magnetic field intensity which aligns nuclei or electrons of the element. There is a second (detection) coil spaced downstream from the first coil, the second coil also being around the pipe. By turning the first coil off or on, the NMR or EMR signal observed at the second coil can be made to change abruptly as the "tagged" element flows to the second coil. By measuring the time of travel of the element of interest evidenced by the second coil signal, the flow velocity can be measured.

In the preferred and illustrated embodiment, a method and apparatus for measuring the flow of non-homogeneous materials in an incompletely filled channel is set forth. In one embodiment, a NMR (or ESR) flow meter arrangement including a magnet forming the requisite magnetic field H. sub. o across a flow channel is incorporated. The magnet cooperates with a coil providing an NMR or ESR output signal from selected specie(s) or sub-atomic patricles (i. e. nuclei or unpaired electrons) in the material in the flow stream. It is desirable for the signal to be representative of the total amount of material in the flow stream. This signal may be in error, unable to sort out prospective combined variations due to (1) incomplete filling of the sensing volume or (2) a non-homogeneous composition of material. A composition sensor coil inscribing a very small volume in selected portions of the flow channel is included to form an NMR output signal indicative of composition, the small volume being filled for that sensor. Its output signal thus determines one of the two variables, and is input to a data combining circuit to indicate the flow volume from the two signals.

A system and method for managing a herd of animals possibly requiring medical treatment, such as cows in a feedlot. The animals are herded individually into a chute, where identification data is collected from a tag, and core temperature data is collected using a special non-contacting core temperature sensor. The animal is tagged with a color coded tag representing a range of temperatures into which that animal's temperature falls. The animal is then delivered to a pen corresponding to that range of temperatures, where appropriate medicinal treatment is automatically dosed and applied to the animal.

600549

A method and apparatus for measuring the core temperature of an animal or human. Thermal black body emissions from the eyeball are detected, at one or more wavelengths selected on the basis of various factors, including the ability of that wavelength to reach the interior of the eyeball. An illumination marker shines a spot of light on the eyeball, such that the spot corresponds to the area from which emissions are being detected.
