Abstract: An antenna assembly includes a base, a lower shell, a heat-dissipating support, an antenna body, and an upper shell. The base includes a base body and a connecting portion connected to each other. The lower shell includes a pivotal base. The pivotal base is located at a first end of the lower shell, and a second end of the lower shell is connected to the connecting portion. The heat-dissipating support includes a bottom portion, a fixed portion, and an extension portion connected in sequence, and the bottom portion is pivotally disposed on the pivotal base. The antenna body includes an adapter board and a first antenna connected to each other. The adapter board includes a fixed end fixed to the extension portion. The upper shell includes an accommodation space configured to accommodate the heat-dissipating support and the antenna body, and the fixed portion is fixed to the upper shell.

Abstract: An exemplary hearing aid compatibility (HAC) module includes an insulative substrate and a ground member. The substrate includes a first mounting surface, and a second mounting surface at opposite sides thereof, and a third mounting surface between the first mounting surface and the second mounting surface. The ground member includes two ground portions respectively attached to the first mounting surface and the second mounting surface, and a connecting portion attached to the third mounting surface. The connecting portion comprises two or more parts. One of the parts connects one of the ground portions, and another of the parts connects the other ground portion.

Abstract: A multiband antenna used for a portable communication device includes a first antenna unit, a second antenna unit, a third antenna unit, and feed member. The first antenna unit, the second antenna unit and the third antenna unit are capable of receiving and/or sending wireless signals. The second antenna unit is connected to the first antenna unit, the third antenna unit is connected to the first antenna unit, and the feed member is electrically connected to the first antenna unit and the second antenna unit. The feed member receives wireless signals and transmits the wireless signals through the first antenna, the second antenna unit and the third antenna unit to generate corresponding current paths, and the first antenna unit is located between the second antenna unit and the third antenna unit to isolate the second antenna unit and the third antenna unit to avoid coupling interference of their resonant frequencies.

Abstract: A communication device includes a first antenna, a second antenna, a power splitter, a switch, and a sensor. The power splitter is electronically connected to the first antenna and the second antenna. The switch is connected to the first antenna and the power splitter. The sensor is installed near the first antenna and may sense a user's body within close proximity. The sensor generates an interrupt signal when sensing a user's body within close proximity. The switch is electronically connected to the power splitter rather than the first antenna in response to the interrupt signal. The switch is electronically connected to the first antenna rather than the power splitter when the interrupt signal is terminated.

Abstract: An antenna module includes an antenna set, a feeding point and a ground plane. The antenna set includes a first antenna, and a second antenna. The first antenna has a first resonant frequency and the second antenna a second resonant frequency.

Abstract: The present invention relates to a method for driving a display adapted for solving afterimage in moving picture and a display driver thereof. The method includes the steps of: dividing a frame of the display into a plurality of areas; dividing a frame period into a first display period and a second display period; displaying a specific color at a specific area of the areas and displaying an image corresponding to a display data in the areas neighbored to the specific area in the first display period; and displaying the specific color at the areas neighbored to the specific area and displaying the image corresponding to the display data at the specific area in the first display period.
