  • Publication number: 20240125758
    Abstract: A method of indicating a characteristic of a soil sample of a field includes measuring a co-factor in the soil sample and using the co-factor to place the soil sample in a soil sample group. The characteristic of the soil sample is measured and then is scaled based on the soil sample group. The scaled measure is displayed to better represent the characteristic of the soil sample relative to soil samples of the sample group.

  • Publication number: 20050101167
    Abstract: A separable electrical connector for separably, electrically interconnecting the conductors of one multi-conductor cable to the conductors of a second electrical device that may be an electrical device such as a chip, or a second multi-conductor cable, or a flexible or rigid printed circuit board. The connector includes a layer of anisotropic conductive elastomer (ACE) in electrical contact with the conductors of the cable and the conductors of the second electrical device. A clamp or another type of mechanical device compresses the ACE, to provide electrical signal paths between the conductors of the cable and the second electrical device, through the ACE.

  • Patent number: 6419526
    Abstract: A multi-port modular jack including an outer housing part, inner housing parts arranged in the outer housing part to define plug-receiving receptacles receivable of mating plugs, and an optional shield surrounding the jack. The outer housing part having a top wall, a bottom wall and a front face having a mid-portion arranged substantially parallel to and between the top and bottom walls. The front face defines a first row of apertures between the mid-portion and the top wall and a second row of apertures between the mid-portion and the bottom wall. Each aperture in the first row has a plane of symmetry offset in relation to a plane of symmetry of each aperture in the second row such that only a portion of each aperture in the first row is directly opposite the opposed apertures in the second row. Vents are formed in the outer housing part to allow for the passage of air through the jack.
