Patents by Inventor Wen Been Li

Wen Been Li 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: 6651648
    Abstract: A kitchen smoke exhauster includes a driving device, a pressure-control device, a time-control device, an enzyme-containing device and a spray device assembled together therewith. A natural and harmless enzyme composition contained in a reservoir of the enzyme-containing device is atomized via the spray device to well mix with the discharging oil vapor for decomposition under the control of the driving device and the pressure-control device. Thus, it is capable of preventing the air of our environment from pollution of cooking fume and avoiding the cooking oil residues therein to cause the danger of a fire so as to further protect the health of our lives.
    Type: Grant
    Filed: March 4, 2002

  • Patent number: 6429533
    Abstract: An electronic device includes a first conductive polymer layer sandwiched between a first external metal foil electrode and a first internal metal foil electrode, a second conductive polymer layer sandwiched between a second internal metal foil electrode and a second external metal foil electrode, a layer of fiber-reinforced epoxy resin bonding the first and second internal electrodes together, a first terminal providing electrical contact between the first internal electrode and the second external electrode, and a second terminal providing electrical contact between the second internal electrode and the first external electrode. In a preferred embodiment, the polymer layers exhibit PTC behavior, and the terminals are formed by a solder layer applied over a plated layer of conductive metal. Insulative layers are preferably provided on the external electrodes, and located so as to insulate the first and second terminals from each other.

  • Patent number: 6242997
    Abstract: An electronic device has three conductive polymer layers sandwiched between two external electrodes and two internal electrodes. The electrodes are staggered to create a first set of electrodes, in contact with a first terminal, alternating with a second set of electrodes in contact with a second terminal.
