    Abstract: It is difficult to check the suitability of a radio anechoic room as a measuring environment, even when countermeasures for preventing reflection of electromagnetic waves and blocking electromagnetic waves are taken against the radio anechoic room and incidental equipment disposed therein, for example. Depending on the circumstances, measurement reliability is decreased when the measurement is taken without recognizing that these countermeasures are insufficient. Therefore, there is a demand for a device that can easily and quickly check whether a measuring environment, such as a radio anechoic room, or a measuring system is suitable for measurement.

  • Publication number: 20080143641
    Abstract: A plasma display device and a driving method thereof. During a sustain period of a first subfield, a sustain discharge alternating waveform alternating between a Vs voltage and a ?Vs voltage is applied to a sustain electrode while a scan electrode is supplied with a constant reference voltage. During an initialization period of a second subfield consecutive to the first subfield, a voltage of the sustain electrode is gradually decreased from a ground voltage to a negative voltage while a scan electrode is applied with the ground voltage, causing a weak discharge to be generated between the scan electrode and the sustain electrode and between the sustain electrode and an address electrode so that wall charges formed on each electrode are partially erased. Accordingly, a scan electrode driver does not need a power recovery circuit by applying the sustain discharge pulse only to the sustain electrode. In addition, an appropriate wall charge distribution can be achieved thus eliminating misfiring.

  • Publication number: 20080143642
    Abstract: A plasma display device and a driving apparatus thereof includes a main switch in order to prevent current from flowing to a power supply that supplies a higher voltage than a negative voltage while the negative voltage is applied to a scan electrode. The main switch is provided only in a current path formed for recovering an energy and applying a ground voltage during the sustain period. Thus, the current that passes through the main switch is reduced and the amount of generated heat is decreased. As a result, the reliability of the main switch can be improved. Further, because the main switch is not provided in a current path formed when the sustain voltage is applied during the sustain period or when the reset rising waveform is applied during the reset period, a distortion of the driving waveform can be prevented.

    Abstract: The object of this invention is to provide a method for moving a cursor using numerical keys. In the cursor movement method, a screen of an information device is divided into sub-screens each. The sub-screens are mapped to respective numerical keys provided on the information device. It is determined whether the numerical keys mapped to the sub-screens have been pressed. The cursor is moved to a sub-screen mapped to a corresponding numerical key and displaying the cursor if it is determined that a numerical key has been pressed. Accordingly, the present invention can easily move the cursor to a desired location in an information communication device lacking a mouse. Therefore, the present invention can perform a function similar to a mouse when a user plays a game, etc. using an information communication device lacking a mouse, such as a mobile phone.
