Portable communication device for responding to incoming call

1. Technical Field

The present disclosure relates to portable communication devices, and particularly to a portable communication device with a ring module.

2. Description of Related Art

Portable telephones often remain in a pocket or a bag when not in use. If a call is incoming, the telephone must be taken out to allow the user to accept or reject the incoming call. However, in some situations, it may be inappropriate to do so.

Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is a block diagram of an embodiment of a portable communication device.

FIG. 2 is a flowchart illustrating an embodiment of an operating method of the portable communication device of FIG. 1 .

Referring to FIG. 1 , an embodiment of a portable communication device 10 , such as a portable telephone or a person digital assistant, includes a ring module 11 , a receiving module 12 , a pulse signal generating module 14 , a timer module 16 , and a detection module 18 .

The receiving module 12 is configured to receive incoming signals to the portable communication device 10 . The ring module 11 rings to indicate that the receiving module 12 is receiving a signal. The pulse signal generating module 14 generates pulse signals when the portable communication device 10 is tapped by the user. There is a first predetermined limit T1 and a second predetermined limit T2 occurring after the first predetermined limit T1. The timer module 16 begins timing when the pulse signal generating module 14 generates the pulse signals, ending at the second predetermined limit T2. The detection module 18 is capable of detecting if the pulse signal generating module 14 generates the pulse signals at the time between the first predetermined limit T1 and the second predetermined limit T2. The detection module 18 is capable of sending a refusal signal to the receiving module 12 if the pulse signals are detected by the detection module 18 , and sending an acceptable signal to the receiving module 12 if no pulse signal is detected by the detection module 18 . The receiving module 12 is capable of refusing or accepting the incoming signals when receiving the refusal or acceptance signal respectively, and simultaneously directing the ring module 11 to stop ringing.

Referring also to FIG. 2 , during use, the receiving module 12 receives an incoming signal and directs the ring module 11 to ring. In response the user taps the portable communication device 10 , the pulse signal generating module 14 generates pulse signals, and the timer module 16 starts timing. At the time between the first predetermined limit T1 and the second predetermined limit T2, the detection module 18 determines if the pulse generating module 14 generates the pulse signals. If so, the detection module 18 sends a refusal signal to the receiving module 12 . The receiving module 12 refuses the incoming signal after receiving the refusal signal, and simultaneously directs the ring module 11 to stop ringing. If no pulse signal is detected by the detection module 18 , the detection module 18 sends an acceptable signal to the receiving module 12 . The receiving module 12 accepts the phone call after receiving the acceptable signal, and simultaneously directs the ring module 11 to stop ringing.

It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
