摘要:
A device (10) includes a passive infrared sensor (20) for user interface. When a user places his finger over the infrared sensor (20), the sensor (20) generate a digital signal indicating the time, position, or movement of the user finger over the sensor (20). A digital signal processing unit (12) processes the digital signal through preinstalled algorithms and generates a command to execute the user instruction through infrared interface. In operation, the user finger does not need to touch or press the infrared sensor (20). In addition, the passive infrared sensor (20) may be packaged under a cover to protect the sensor (20) from hazardous elements in the environment.

A method for performing a function of giving notice according to positions are provided, which enables performing a function of giving notice by not only setting a predetermined time but setting a predetermined position. The function s of giving notice is performed when the predetermined time is up or reached, or when the positioning unit of the mobile electronic device detects that a user reaches a point within a predetermined accuracy range of the predetermined position. This disclosure performs the function of giving notice by combining both ways of determining if the predetermined time is up or reached and if a io user reaches a point within the predetermined accuracy range of the predetermined position to overcome the disadvantages generated by only setting the predetermined time. Therefore, the disclosure provides more flexible ways for a user when taking positions as the first priority not a particular time point.

The present invention is to provide a method of automatically enabling or disabling backlight of an electronic device based on a predetermined time, which is implemented in the electronic device including a memory having an established backlight control database containing a predetermined enabled and disabled time of backlight respectively. In response to a user pressing a key of the keypad as determined by the electronic device, the electronic device is able to automatically read and inquire the predetermined enabled or disabled time of backlight, and activate or deactivate the keypad backlight immediately when a predetermined condition (i.e., the predetermined enabled or disabled time of backlight) has been reached.

A method for retrieving vocabulary entries in a mobile phone is disclosed. The mobile phone includes a screen and a text file. The text file has a plurality of vocabulary entries. Each vocabulary entry is stored in a number of languages in the same text file. The method includes opening files according to the number of languages in the text file, storing vocabulary entries expressed in the same language in the same file, giving a same index for every vocabulary entry having the same meaning expressed in different languages, according to the index retrieving the vocabulary of the same meaning expressed in a different language in one of files, and displaying the vocabulary entry on the screen.

The present invention discloses an apparatus and a related method for achieving the purpose of improving the computer performance while inputting characters by using personal digital assistant (PDA) devices. The parallel port of the computer is connected with the PCMCIA (Personal Computer Memory Card International Association) card of the PDA device, and then a handshaking scheme is applied to establish a connection between the PC and the PDA device. After the connection has been successfully established, the input characters are transferred from the PDA device by parallel transformation without increasing the loading of the computer.
摘要:
In a computer database synchronization method, a first database with first object data and a second database with second object data are established in a personal computer and an electronic dictionary, respectively. First and second synchronization status tables are established for each of the first and second object data, respectively. The synchronization status tables are modified from a first state, indicating that the corresponding object data is synchronized with the first or second database, to a second state, indicating that the corresponding object data is not synchronized with the first or second database, when the corresponding object data is edited. Synchronizing of the first and second databases can begin when a communications link is established between the personal computer and the electronic dictionary. During synchronizing, the personal computer retrieves the second synchronization status tables from the electronic dictionary, and compares the second synchronization status tables with the corresponding first synchronization status tables. Based on the results of the comparison, the personal computer retrieves the corresponding second object data from the electronic dictionary, and updates the first database with the retrieved second object data, or transmits the corresponding first object data to the electronic dictionary for updating the second database with the transmitted first object data.
