  • Patent number: 7486980
    Abstract: A bio-monitoring apparatus is disclosed in the present invention which is characterized in that a bio-sensing electrode without a stud member or male portion of a snap fastener is directly integrated with a signal processing module through a conductive layer formed therebetween so as to form the bio-monitoring apparatus functions to transcutaneously sense physiological statuses of a being. In a preferred embodiment of the present invention, the structure of the bio-sensing electrode is further simplified to a contacting layer coupled to the signal processing module through the conductive layer so as to reduce attenuation of signal intensity during signal transmitting. Meanwhile, without the stud member disposed in the electrode, not only the thickness of the electrode is certainly reduced, but also the feeling of comfort is capable of being improved while the electrode is adapted to contact a being.

  • Publication number: 20070141887
    Abstract: A waterproof electrical power connector is provided. The male member of the connector includes magnetic core surrounded with a winding, and the female member of the connector includes a winding and has a hollow for receiving the male member. As the male member is inserted into the female member and a current passes through the male member winding, the induced magnetic flux is coupled to the female member winding, which accordingly induces current in the female member.
