Abstract

The present invention is to provide a cellular phone capable of detecting counterfeit currency or lighting comprising a counterfeit currency detection bulb, a lamp and a keypad, wherein the keypad includes a first dual key in association with the counterfeit currency detection bulb, a second dual key in association with the lamp and a plurality of third keys, such that in response to pressing the first dual key or the second dual key, the cellular phone activates the counterfeit currency detection bulb for detecting counterfeit currency or activates the lamp for lighting respectively.

Claims

1. A method of either detecting counterfeit currency or lighting by means of a cellular phone including a counterfeit currency detection bulb, a lamp, a display, a CPU, an MMI, a keypad driver, a counterfeit currency detection driver, a lighting driver, and a keypad including a first dual key in association with a counterfeit currency detection bulb, a second dual key in association with a lamp, and a plurality of third keys so that either in response to pressing the first dual key, the CPU performs steps comprising:

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof; and

running the counterfeit currency detection driver to activate the counterfeit currency detection bulb;

or in response to pressing the second dual key, the CPU performs steps comprising;

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof; and

running the lighting driver to activate the lamp,

wherein the cellular phone is a hinge type of cellular phone include a phone body and a cover wherein one end of the phone body is hingedly coupled to one end of the cover so that in one state the cover is pivoted to rest on the phone body for covering the keypad, on one side of the phone body there are formed a volume increase key and a volume decrease key, and the volume increase key or the volume decrease key is operative to press to adjust a volume of the hinge type of cellular phone when the cover of the hinge type of cellular phone is open.

2. The method of claim 1, wherein in response to closing the cover on the phone body and pressing the volume increase key, the CPU performs steps comprising:

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof;

determining whether the cover is closed on the phone body or not;

if the determination is positives running the counterfeit currency detection driver to activate the counterfeit currency detection bulb; and

if the determination is negatives increasing the volume of the hinge type of cellular phone.

3. The method of claim 1, wherein in response to closing the cover on the phone body and pressing the volume increase key, the CPU performs steps comprising:

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof;

determining whether the cover is closed on the phone body or not;

if the determination is positives running the lighting driver to activate the lamp; and

if the determination is negative, decreasing the volume of the hinge type of cellular phone.

4. A method of either detecting counterfeit currency or lighting by means of a cellular phone including a counterfeit currency detection bulb, a lamp, a display, a CPU, an MMI, a keypad driver, a counterfeit currency detection driver, a lighting driver, and a keypad including a first dual key in association with a counterfeit currency detection bulb, a second dual key in association with a lamp, and a plurality of third keys so that either in response to pressing the first dual key, the CPU performs steps comprising:

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof; and

running the counterfeit currency detection driver to activate the counterfeit currency detection bulb;

or in response to pressing the second dual key, the CPU performs steps comprising;

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof; and

running the lighting driver to activate the lamp,

wherein the cellular phone is a coverless type of cellular phone including a phone body, on a surface of the cellular phone there are formed the display and the keypad including a “

#”

key, a “

*”

key, and the plurality of third keys, a pressing of the “

#”

or the “

*”

key deactivates the pressing state thereof with the pressed “

#”

or “

*”

key being shown on the display, and a continuous pressing of the “

#”

or “

*”

key activates the counterfeit currency detection bulb or the lamp respectively.

5. The method of claim 4, wherein in response to continuously pressing the “

#”

key, the CPU performs steps comprising;

receiving an interrupt signal;

running the keypad drive to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof;

determining whether the “

#”

key is pressed continuously or not;

if the determination is positive, running the counterfeit currency detection driver to activate the counterfeit currency detection bulb; and

if the determination is negative, showing “

#”

on the display.

6. The method of claim 4, wherein in response to continuously pressing the “

*”

key, the CPU performs the steps comprising;

receiving an interrupt signal;

running the keypad driver to scan the key being pressed;

running the MMI to determine the key being pressed and a meaning thereof;

determining whether the “

*”

key is pressed continuously or not;

if the determination is positive, running the lighting driver to activate the lamp; and

if the determination is negative, showing * on the display.
