摘要:
The present invention discloses a high voltage resisting keyboard comprising at least one press key on a casing, a circuit board inside the casing, and a metal dome between the press keys and the circuit board inside the casing, wherein the edge of the metal hemisphere of the metal dome is directly connected to an end of an electrode of the circuit board, and the other end of the electrode is connected to an end of a resistor. Thus, when the edge of the metal hemisphere receives the high voltage current, the keyboard is protected by the resistor to avoid the high voltage current from being sent directly to another end of the resistor that is connected to another electronic component to achieve the purpose of protecting another electronic component.

A touch control input system and a signal generation method are provided. The touch control input system includes a touch control interface, a sensor unit, and a control unit. The touch control input system is featured by sectioning a plurality of blocks based on a plurality of grid lines for constructing the touch control interface so as to identify the displace movement of an external operator based on the blocks. The sensor unit functions to detect changes of logic states of the blocks. Accordingly, the control unit is able to identify the displace movement from one grid line to the other grid line through the detected changes of logic states, which in turn can be utilized to generate a displacement data for controlling electronic apparatuses.

A light spot control system, using a projection light of a projection device to initiate a control of a mobile communication device, includes an I/O unit and a processing unit. The I/O unit is used to receive the projection light. The processing unit is used to provide a time value and a position value. The time value is a duration of the projection light stayed at the I/O unit, and the position value is a position of the projection light stayed at the I/O unit. When the time value meets a default value, the respective position value is used to perform the control.

This invention discloses a portable communication apparatus having an optical character recognition (OCR) function. The apparatus at least contains an optical input unit, a processing unit and an edition unit. After the optical input unit obtains the image information which is further transformed by the processing unit to letters which can be processed by the portable communication apparatus, the edition unit then can edit and/or store the letters into the portable communication apparatus to finish the OCR function.

The present invention discloses a method for balancing the data access to a non-volatile memory by sorting a block number of an unwritten memory block of a non-volatile memory with a queue structure. If the data in any memory block of the non-volatile memory is erased, the block number of the memory block in which the data is erased will be appended to the tail of the queue. If a data is written into the non-volatile memory, a block number of the memory block is obtained from the head of the queue and the desired data is written into the memory block with the corresponding block number, and in the meanwhile the block number is deleted from the queue.

A system to be used to add non-listed characters (i.e., characters not listed in character key-in methods) to the vocabulary banks of character-key-in methods used in hand-held mobile communication devices is disclosed. Users of a mobile communication device can select a character or characters which are built in the system but not indexed by a certain character-key-in method (that is, the characters cannot be keyed in with that character-key-in method), index the aforesaid characters, using the indexing system/method of the character-key-in method, and then add them to the key-in method's character-indexing system so that subsequent users of the mobile communication device can use said character-key-in method to key in said (originally non-indexed/listed) characters.

The present invention is to provide a cellular phone capable of measuring temperature including a liquid crystal display, a CPU and an IR temperature measurement means coupled to the CPU, wherein a first GPO pin and a second GPO pin of the CPU are adapted to control power supply of a power supply IC and start or stop of the IR temperature measurement means respectively, and in response to receiving a temperature measurement signal, the CPU performs a plurality of processing and conversion steps to show a corresponding temperature on the display.
摘要:
An apparatus for extending “phone book” records of a subscriber identification module (SIM) card comprising a detecting module for accessing a subscriber identification code (SIC) of the SIM card and a memory is provided. A storage window marked by the SIC is defined in the memory. As the user edits the “phone book” records of the SIM card, a portion of the records is stored in the marked storage window.
