Patents by Inventor Henry Jun

Henry Jun 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: 10666152
    Abstract: A switching power converter is provided with a phase-shifting RC network for phase-shifting a divided version of a drain voltage of a power switch transistor into a phase-shifted voltage. A comparator compares the phase-shifted voltage to a DC bias voltage to detect peaks and valleys during resonant oscillations of the drain voltage of the power switch transistor.
    Type: Grant

  • Patent number: 8715726
    Abstract: The present invention relates to a pharmaceutical composition comprising a combination of active principles. More specifically: a stable pharmaceutical composition comprising a combination of tramadol and ketoprofen. Furthermore, a combination in solid form in which the active principles are vehicled in pharmaceutical forms and/or products that prevent contact between them. Complementarily, the present invention also relates to the combined use of ketoprofen and tramadol in the preparation of an oral medicine useful for relieving pain as well as a method for relieving pain with an oral pharmaceutical composition comprising a combination of tramadol and ketoprofen.
