DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a method and an apparatus of estimating the intensity of the electromagnetic wave of a mobile communication device.

A preferred embodiment of the present invention is a method of estimating the intensity of the electromagnetic wave of a mobile communication device. Please refer to FIG. 1. FIG. 1 is a flow chart illustrating the method of estimating the intensity of the electromagnetic wave according to the preferred embodiment.

Firstly, step S10 is performed in the method of the invention to retrieve a transmission power of the mobile communication device. Secondly, step S12 is performed in the method of the invention to estimate the intensity of the electromagnetic wave based on the transmission power. Finally, step S14 is performed in the method of the invention to display the intensity of the electromagnetic wave.

In a practical application, when estimating the intensity of an electromagnetic wave based on the transmission power in the method, the transmission power could be compared with a look-up table which stores a plurality of sets of power range and a plurality of default intensities of electromagnetic waves, and each set of power range is corresponding to one of the plurality of default intensities of electromagnetic waves respectively, so the intensity of the electromagnetic wave can be obtained from the plurality of default intensities of electromagnetic waves.

Moreover, in another practical application, a mathematical transformation equation could be used to estimate the intensity of electromagnetic wave based on the relation between the transmission power and the intensity of electromagnetic wave.

Another preferred embodiment of the present invention is also a method of estimating the intensity of the electromagnetic wave of a mobile communication device. Please refer to FIG. 2. FIG. 2 is a flow chart illustrating the method of estimating an intensity of an electromagnetic wave according to the preferred embodiment.

As illustrated in FIG. 2, the method of estimating the intensity of the electromagnetic wave in FIG. 1 further comprises step S16 and step S18. In practical applications, the intensity of the electromagnetic wave is not necessarily shown on the screen of the mobile communication device immediately.

For example, step S16 could be performed in the method to store the intensity of the electromagnetic wave in a memory. Once users send an inquiring request by the man machine interface (MMI) to inquire the intensity of the electromagnetic wave of the mobile communication device, step S18 and step S14 could be performed to read the intensity of the electromagnetic wave stored in the memory and the screen of the mobile communication device displays the stored intensity of the electromagnetic wave.

Furthermore, the method of the present invention could further statistically analyze the intensity of the electromagnetic wave stored in the memory. Users could inquire the statistically analyzed result of the intensity degree of the electromagnetic wave and use it as a reference while operating the device.

Yet another preferred embodiment of the present invention is an apparatus of estimating the intensity of the electromagnetic wave of a mobile communication device. Please refer to FIG. 3. FIG. 3 is a functional block demonstrating the apparatus of estimating the intensity of the electromagnetic wave according the preferred embodiment of the present invention.

The apparatus of estimating an intensity of an electromagnetic wave 30 comprises a retrieving module 31, an estimating module 32 and a display module 33. The retrieving module 31 is for the retrieving of a transmission power of the mobile communication device. The estimating module 32 is for the estimating of the intensity of the electromagnetic wave according to the transmission power. The display module 33 is for the displaying of the intensity of the electromagnetic wave.

In practical applications, the estimating module 32 compares the transmission power with a look-up table to obtain the intensity of an electromagnetic wave. The look-up table stores a plurality of sets of power ranges and a plurality of default intensities of electromagnetic waves, and each set of power range is corresponding to one of the plurality of default intensities of electromagnetic waves. After the estimating module 32 compares the transmission power with the look-up table, the intensity of the electromagnetic wave could be obtained from the result chosen among the plurality of default intensities of electromagnetic waves.

Additionally, in practical applications, the estimating module 32 could estimate the intensity of electromagnetic wave based on the relation between the transmission power and the intensity of electromagnetic wave by means of a mathematical transformation equation.

As illustrated in FIG. 4, according to another embodiment, the apparatus of estimating the intensity of the electromagnetic wave 30 could further comprise a memory 34 and a statistic module 35.

The memory 34 is for the storing of the intensity of the electromagnetic wave. The statistic module 35 is for statistically compiling the intensity of the electromagnetic wave. The retrieving module 31 could store the retrieved intensity of the electromagnetic wave in the memory 34. The statistic module 35 is for reading the intensity of the electromagnetic wave stored in the memory 34 and statistically analyzing the stored intensity of the electromagnetic wave.

Once users send an inquiring request by the man machine interface (MMI) to inquire the intensity of the electromagnetic wave, the apparatus for estimating an intensity of an electromagnetic wave 30 reads the data from the memory 34 and displays the statistically analyzed result on the screen. Thereby, users could use it as a reference while operating the device.

Please continuously refer to FIG. 4, for example, the transmission power of the mobile communication device could be divided into five sets of power range, these sets of power range are stored in a look-up table in the memory 34. The five sets of power range are corresponding to five intensity degrees of electromagnetic waves respectively.

The memory 34 also stores the definition of each intensity degree of the electromagnetic wave. Users could send an inquiring request by the man machine interface (MMI) to inquire the definition of the intensity of an electromagnetic wave. Meanwhile, the apparatus of estimating an intensity of an electromagnetic wave 30 reads the data from the memory 34 and displays the definition of intensity of the electromagnetic wave on the screen. Thus, users could use it as a reference while operating the device.

For example, the statistic module 35 of the mobile communication device could read the intensity of the electromagnetic wave stored in the memory 34, which shows it is over the third intensity degree during a specific period (such as in one day, in a week, in a month or in a year), and statistically compiles the number of times. Furthermore, the statistic module 35 could compile the total time of operation on the mobile communication device when the intensity of the electromagnetic wave is over the third intensity degree. Thus, users could use it as a reference while operating the device.

Please continuously refer to FIG. 4. In an extra embodiment, the mobile communication device could also be integrated with a warning unit. For example, when the intensity of the electromagnetic wave reaches the fifth intensity degree, then the apparatus for estimating an intensity of an electromagnetic wave 30 drives the warning unit to display a warning message says “the intensity of the electromagnetic wave is too high” on the display module 33, or drives the mobile communication device to vibrate to warn the users.

Compared to prior art, the method and the apparatus of estimating an intensity of an electromagnetic wave of the invention reaches the effect without adding any extra measuring machines and cost.
