Chang Yong Ryu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8165652
    Abstract: Provided is a physiological signal detection module which has a heating member and a multi-channel connector. The heating member maintains an electrode's contact with a user skin at a constant temperature, and the multi-channel connector module for electrical connection transmits the physiological signal to an external physiological signal detection apparatus. It is possible to prevent the skin from being directly contacted with the electrode in the cold state and have a less impact given by a change of the impedance due to a skin temperature based on the change of the season and external temperature, so that the stable physiological signal can be detected without distortion.
    Type: Grant

  • Patent number: 7395106
    Abstract: Provided are a wearable physiological signal detection module and a measurement apparatus having the same. A physiological signal detection module including a measuring electrode implemented by a dry electrode having good conductivity to detect various physiological signals is detachably disposed inside the clothing closely adhered to user's skin. The measuring electrode can be in stable contact with the user's skin as well as the detection module can be conveniently worn for a long time. The various physiological signals detected by the measuring electrodes are wirelessly transmitted to an external device, thereby conveniently monitoring the physiological signal of the user in real time.

  • Patent number: 7162295
    Abstract: Provided are an apparatus and a method for recognizing positive/negative intention using a fine change of gamma wave of a brainwave comprising the steps of detecting the brainwave from a head of a user, receiving and amplifying the brainwave detected from the step of detecting the brainwave, converting the amplified analog brainwave to one of a digital type, and recognizing the positive/negative intention of the user by detecting the fine change of the gamma wave of the brainwave in the digital type, which is transmitted from the A/D converting portion, whereby it is possible to implement an application of a real time interface and minimizes inconvenience for the user, and it requires no separate user practice.
