PURPOSE: A portable terminal is provided to promote the convenience of a user by eliminating additional tools in the portable terminal. CONSTITUTION: A sensing unit(104) senses an outside force. A carrier(105) transfers the outside force to the sensing unit. A data processing unit receives the outside force. The data processing unit is connected with the sensing unit and a display unit(101). A small housing unit(100a) accepts the display unit, the sensing unit, the carrier, and the data processing unit. The small housing unit exposes the carrier.

PROBLEM TO BE SOLVED: To provide a speed measuring method and a system therefor in which computing speed and measurement accuracy are improved in a speed measuring process, and a circuit occupation area and power consumption are reduced.SOLUTION: In the speed measuring method and the system therefor, speed measuring/computing of a measured object is performed by using a distance value and a time value obtained by a distance measuring method and a time measuring method. The time value is obtained, using a clock mask synchronized with a reference signal and distance measurement operation, by obtaining the number of cycles of the reference signal under the clock mask and on the basis of the number of cycles, the time value during the distance measurement operation while the time value is corrected by using a plurality of phase shift signals generated on the basis of the reference signal and errors are more reduced with an increase of the number of phase shift signals, so that a correct time value during the distance measurement operation is obtained. The speed measuring method and the system therefor also have advantages of a high measurement speed and a small occupation circuit area.

PROBLEM TO BE SOLVED: To provide a distance measuring method and a system therefor in which computing speed and measurement accuracy are improved in a distance measuring process and a circuit footprint and power consumption are reduced.SOLUTION: In the distance measuring method and the system therefor, a distance is computed by using a light speed value and a time value representing a time required for a light signal to make a round trip between the system and a measured object. A clock mask synchronous with transmission/reception of the light signal is used to determine the number of cycles of a reference signal with the clock mask and obtain a time value through conversion. The time value is corrected by using a plurality of phase shift signals generated on the basis of the reference signal and errors are further reduced along with increase of the number of phase shift signals, so that a correct time value representing the time required for the light signal to make a round trip between the system and the measured object is determined. The distance measuring method and the system therefor also have advantages of a high measurement speed and a small circuit area occupied by the measuring system.

The frequency counter also has advantages of a high measurement speed and a small occupation circuit area.

PROBLEM TO BE SOLVED: To provide an overvoltage protection circuit.SOLUTION: In an overvoltage protection circuit, there is provided overvoltage protection which is designed to ensure that an input voltage supplied between a voltage source and a portable electronic device will not exceed the permissible rated withstand voltage of the portable electronic device. The overvoltage protection circuit receives an input voltage generated from the voltage source through an input unit, and the input voltage generates a divided voltage through a voltage dividing module, so that a voltage stabilization module generates a first control signal which allows a first switching unit to enter a short-circuit state or an open-circuit state, or indirectly controls a second switching unit so as to place it into a short-circuit or an open-circuit state which is opposite to that of the first switching element. When the input voltage exceeds the rated voltage, the input voltage supplied to the portable electronic device is stopped through the second switching unit, whereby overvoltage protection is realized without being affected by temperature.
