  • Multiband antenna
    Patent number: 8659492
    Abstract: A multiband antenna includes a feed unit, a transceiving unit, and a resonance unit positioned adjacent to but separate from the feed unit and the transceiving unit. When feed signals are input to the feed unit, the feed signals are transmitted to the transceiving unit to form current paths of different lengths, and the resonance unit is driven to resonate and generates additional current paths of different lengths. In this way, the transceiving unit and the resonance unit are enabled to respectively receive and send wireless signals of different frequencies, and thus the multiband antenna is capable of receiving and sending wireless signals in more than two frequency bands.

  • USB-on-the-go bi-directional protection circuit
    Patent number: 8627121
    Abstract: A power management circuit for managing power of an electronic device includes a regulator and a protection circuit. The regulator converts an input voltage into a corresponding rated voltage and includes an enable pin and an output pin. The enable pin receives a voltage signal to enable or disable the regulator, and the output pin selectively outputs the rated voltage. When the electronic device is implemented as a slave universal serial bus (USB) device and the enable pin receives a low voltage signal, the regulator is disabled, and the protection circuit receives an output voltage. When the electronic device is implemented as a USB host and the enable pin receives a high voltage signal, the regulator is enabled, and the output protection circuit outputs the rated voltage.
