  • Patent number: 10277302
    Abstract: A signal-repeating device for extending a control area and signal-repeating method thereof are provided. The signal-repeating device includes a first connection port, a second connection port, a repeating circuit, a communication-monitoring module and a processing unit. The first connection port is coupled to a first antenna. The first antenna supports a first frequency band and a second frequency band. The second connection port is coupled to a second antenna. The repeating circuit is coupled between the first connection port and the second connection port to repeat signals between a base station and a mobile station via the first antenna and the second antenna through the first frequency band. The communication-monitoring module is connected to a user terminal via the first antenna through the second frequency band. The processing unit is coupled to the repeating circuit and the communication-monitoring module. The first frequency band does not overlap the second frequency band.

  • Publication number: 20090002337
    Abstract: A capacitive-type touch panel includes: a transparent substrate; a plurality of first conductors; a plurality of second conductors cooperating with the first conductors to form a matrix of capacitive regions; and a controller connected electrically to the first and second conductors for detecting the capacitance of each of the capacitive regions. Each of the first conductors is intersected and divided by the second conductors into a series of first electrode sections. Each of the second conductors is intersected and divided by the first conductors into a series of second electrode sections. Each of the first and second electrode sections of the first and second conductors has a fine conductor line-constructed structure which is constructed from a fine line-shaped conductor.
