Abstract: A chip package structure is provided. The chip package structure includes a chip. The chip package structure includes a conductive ring-like structure over and electrically insulated from the chip. The conductive ring-like structure surrounds a central region of the chip. The chip package structure includes a first solder structure over the conductive ring-like structure. The first solder structure and the conductive ring-like structure are made of different materials.

Abstract: A mobile phone and method for searching a phonebook of the mobile phone are provided. The method can search the phonebook of the mobile phone when the mobile phone is in a low power state. The method defines a first predefined voltage and a second predefined voltage for the mobile phone when the mobile phone is powered on. The method further measuring a battery voltage of the mobile phone, and controls the mobile phone to work in a phonebook mode if the battery voltage is less than the first predefined voltage. In addition, the method generates a phonebook search interface when the mobile phone works in the phonebook mode, and searches a phonebook according to search conditions input from the phonebook search interface.

Abstract: The invention relates to a data structure and operation method for A/V (audio/video) disks. The specification disclosures a type of navigation files with a new structure. This navigation file utilizes a plurality of tables with different data types to record data relevant to another A/V file in the disk. To distinguish different data types of tables, each table has a table head and a table serial number. There is also an erase/modify information table in each of the data types to record editing information that has been done (such as editing information of erase/modify). Any newly created or edited table is written to a disk by appending. When first using an A/V player to play A/V data, all the tables are combined into a navigation file through the steps of separating tables, modifying tables and rearranging table. Thus, newly created or edited A/V data in an A/V disk can be played without the need to modify the original navigation file in the disk.
