Patents by Inventor Kuei-Yung WU

Kuei-Yung WU 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: 11073418
    Abstract: A liquid level sensing device and a packing structure are provided. An outer tube fastener is connected to a signal module. A protective soft tube is connected to the outer tube fastener. An end of a double-layer flexible tube is connected to the protective soft tube. The double-layer flexible tube includes a flexible conductive outer tube and a fluorine-containing plastic inner tube coaxially attached in the flexible conductive outer tube. The fluorine-containing plastic inner tube is made of a flexible material. The flexible conductive outer tube is made of a conductive flexible material to form a grounding layer. A sensing module is disposed in the fluorine-containing plastic inner tube. A magnetic floater is assembled outside the double-layer flexible tube. A hanger is connected to another end of the double-layer flexible tube.

  • Patent number: 10145721
    Abstract: A flexible float-type liquid level measurement device includes an outer tube securement member, a signal connection module, a flexible outer tube, a suspension member, a flexible supporting unit and a magnetic floating ball. The signal connection module is arranged on one end of the outer tube securement member. The flexible outer tube is connected to the outer tube securement member. The suspension member is connected to another end of the flexible outer tube. The flexible supporting unit is arranged inside the flexible outer tube, and the flexible supporting unit includes one end connected to the outer tube securement member and another end connected to the suspension member. The magnetic floating ball is moveably mounted onto the flexible outer tube. Accordingly, the elongated deformation of the flexible outer tube can be prevented while the measurement accuracy and useful lifetime of the measurement device can be increased.
