  • Patent number: 10404229
    Abstract: An EMI filtering, coaxial power connector may be formed as an inline component or a port of a device. The connector may have dimensions to accept F-type coaxial connectors. The connector includes a conductive outer shell with a first opening and a second opening. A dielectric member is disposed within the shell. A conductive pin is supported by the dielectric member. A feed-through capacitor has a central opening and a first lead formed within the central opening. The pin is electrically connected to the first lead. A second lead of the capacitor is formed at an outer perimeter of the capacitor and is electrically connected to the shell. A metal plate is mounted within the shell. The plate is disk-shaped with a central hole. An outer perimeter of the plate is in electrical contact with the shell. The pin passes through the central hole without making electrical contact with the plate, and the plate resides between the second opening of the shell and the capacitor.

  • Patent number: 8085038
    Abstract: A noise-testing method for a thin-film magnetic head with an MR read head element and a heating unit capable of applying a heat and a stress to the MR read head element, includes a step of applying alternately and discontinuously with each other an electrical power having a first level and an electrical power having a second level higher than the first level to the heating unit, and a step of evaluating the thin-film magnetic head by measuring a noise output or noise outputs obtained from the MR read head element when the electrical power or the electrical powers are applied to the heating unit.

  • Patent number: 7479111
    Abstract: Disclosed is a method for measuring an arterial blood pressure of a subject comprising detecting a pulse-wave-related signal of the subject; extracting a feature from the signals; determining a factor that can affect the arterial blood pressure of the subject; and determining the arterial blood pressure based on the feature with an automatic compensation for the factors. The disclosed method reduces the error in measuring the blood pressure based on characteristics of the pulse-wave-related signals.
