  • Patent number: 10806046
    Abstract: A package structure of a power module is provided. The package structure includes a body having a sidewall, a first protruding structure protruding outward from one end of the sidewall, a second protruding structure protruding outward from another end of the sidewall and opposite to the first protruding structure, and a spring having two ends embedded in the first and the second protruding structures, respectively. The stress is transferred to the first and the second protruding structures via the spring, respectively. The equivalent stiffness of the spring is different from that of the body so that the package structure as a whole suffers the stress uniformly.

  • Publication number: 20160238433
    Abstract: An electronic device includes a housing, a touch panel, a processor and one or more conductive rubbers. The touch panel has a contact surface. The processor is disposed inside the housing and coupled to the touch panel. When the one or more conductive rubbers contact the contact surface of the touch panel and the one or more conductive rubbers are compressed by a gravity provided by an object, the processor detects a first value on touch panel and obtains a weight of the object according to the first value.
