  • Patent number: 10361477
    Abstract: An antenna and a mobile terminal having the same are provided. The antenna includes: a metal shell having a first slot, penetrated through the metal shell, extending in a transverse direction of the metal shell, having two ends which are closed; and a second slot, penetrated through the metal shell, extending in a longitudinal direction of the metal shell, having a first end communicated with the first slot and a second end extending to an edge of the metal shell and opened thereat; an exciting sheet disposed at an inner side of the metal shell, covering the first slot in a width direction thereof; a dielectric filling layer disposed between the exciting sheet and the metal shell, configured to fill the first and second slots; and an expanding resonance branch, disposed on a surface of the dielectric filling layer facing away from the metal shell, connected to the exciting sheet.

  • Patent number: 9267224
    Abstract: The present invention provides a laundry processing apparatus (100), which includes: a laundry processing drum (22), used for holding laundry for processing; a driving system (30), used for driving the laundry processing drum (22) to process the held laundry; and a power control system (10), at least used for providing power of a grid for the driving system (30), where the power control system (10) includes an electrical storage device (11). Through the setting, when external grid power outage occur or the fluctuation of the voltage is excessively large, the power control system may switch a power storage device to supply power to the laundry processing apparatus, thereby eliminating the influence on the apparatus caused by unstable voltage of power transmitted by the grid or grid power outage, and avoiding the trouble brought to a user.
