Patents by Inventor Jia-Hsing Wu

Jia-Hsing 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).

  • Proximity sensing method, proximity sensing apparatus and mobile platform using the same
    Patent number: 9162360
    Abstract: A proximity sensing apparatus is provided. The proximity sensing apparatus includes an encoded signal transmission unit, an interference signal transmission unit and a reception unit. The encoded signal transmission unit transmits an encoded signal, and the interference signal transmission unit transmits an interference signal. The interference signal interferes with the encoded signal to generate an interfered signal. The reception unit receives a sensing signal and outputs the sensing signal to a signal processing unit. The sensing signal is either the interfered signal or the encoded signal. The signal processing unit is electrically connected to the reception unit, and determines whether the sensing signal matches the encoded signal. The signal processing unit further outputs a proximity signal when the sensing signal does not match the encoded signal.

  • Suction cleaner and operation method thereof
    Patent number: 9055848
    Abstract: A suction cleaner and an operation method thereof are provided. The suction cleaner includes a housing, a holding part, an impeller module, at least one sensing device, and a controller. An end of the housing has a dust-suction opening. The impeller module is located inside the housing, and a channel is located between the impeller module and the dust-suction opening. The controller is electrically connected to the sensing device to drive and adjust the rotation rate and the suction force of the impeller module, and thus the power consumption of the suction cleaner can be reduced.
