A power saving method and system thereof is disclosed. When the central processing unit is under a non-snooping sleep state and a peripheral device sends a bus master request, a chip will drive the central processing unit waking from the non-snooping sleep state and entering a system management mode for executing an interrupt service routine that makes the central processing unit in halt status. The central processing unit is then driven to enter a snooping sleep state for snooping the bus master request. After the execution of the bus master request, the chip will drive the central processing unit to leave the snooping sleep state and return to the non-snooping sleep state for power consumption conservation.

A high-density fine line structure mainly includes: two boards with similar structures and a dielectric film for combing the two boards. Semiconductor devices respectively in two boards are opposite to each other after the two boards are combined. The two boards each include a fine line circuit, an insulated layer on the same surface, and the semiconductor device installed above the fine line circuit. The surface of the circuit, which is not covered by a solder mask, is made into a pad. The pad is filled with the tin balls for electrically connecting with another semiconductor device. Electroplating rather than the etching method is used for forming the fine line circuit layer, and a carrier and a metal barrier layer, which are needed during or at the end of the manufacturing process, are removed to increase the wiring density for realizing the object of high-density.

A mobile device capable of running at least two operating systems (OS), and a method for sharing a wireless communication module between the operating systems are provided. A hardware controller is configured to communicate between the two operating systems. First, a first operating system encodes an instruction into a first uniform message and transmits the first uniform message to a second operating system, in which the wireless communication module is installed, through the hardware controller. Afterwards, the second operating system enables the wireless communication module to start receiving positioning data according to the first uniform message, encodes the data into a second uniform message, and sends the second uniform message back to the first operating system through the hardware controller. Finally, the first operating system decodes the second uniform message into positioning data.

An electromagnetic induction heating grill toaster that includes a first casing body, a first baking tray, a second casing body, and a second baking tray. The first casing body has a first electromagnetic induction element, a first micro-crystal plate, and a control element. The first baking tray is detachably disposed on the first casing body. The second casing body has one side pivoted on one side of the first casing body and has a second electromagnetic induction element and a second micro-crystal plate. The second baking tray is detachably disposed on the second casing body. The present invention utilizes the advantage of quick heating of electromagnetic induction, in order to reduce the amount of time users need to wait for the grill toast to preheat. Hence, the present invention not only reduces power use, but also saves time for the user.

A debugging device and method are provided, including a central processing unit (CPU) connected to a chipset with a system management interrupt pin. The debugging method includes sending out a system management interrupt signal to central processing unit from the system management interrupt pin of the chipset. Then the CPU moves into a system management mode and pops out a debugging operation window for selecting and executing each debugging item. After the execution of each debugging item is completed, the CPU will leave the debugging operation window and return to the next instruction before debugging. After the execution of each debugging item is completed in the debugging operation window, the CPU will return to the operation system and continue the execution of next instruction before debugging. The execution of debugging will not influence the status and the program execution from the operating system. The disclosed debugging method is convenient for executing each debugging item at any time.

摘要:
A laser peening process for the densification of metal surfaces and sub-layers and for changing surface chemical activities provides retardation of the up-take and penetration of atoms and molecules, particularly Hydrogen, which improves the lifetime of such laser peened metals. Penetration of hydrogen into metals initiates an embrittlement that leaves the material susceptible to cracking.

A method for measuring a tilt angle of a pickup head. The method includes the steps of: moving the pickup head to a track to be measured; radiating a laser beam with a constant power; defining a proper range of tilt control values; controlling the tilt angle of the pickup head according to the range of tilt control values, acquiring a RF signal corresponding to each tilt control value, and storing an associated value of a associated signal; detecting the maximum among the stored associated values; selecting and storing the tilt control value corresponding to the maximum as the optimum tilt control value for the track if there is a maximum; and modifying the range of tilt control values and executing the previous steps if there is no maximum. The so-called associated signal includes a tracking error signal, a reading/writing RF signal, an S-curve signal, or the RF signal.

摘要:
A composite circuit board comprises multiple soft panels evenly mounted on a rigid panel. The soft panels are positioned on the rigid panel in proper alignment via locating pins on the rigid panel and corresponding holes in the soft panels. The soft panels are securely bonded to the rigid panel to form the composite circuit boards. The smaller size of the soft panels minimizes the alignment problems caused by the different heat expansion rates of the soft panel and the rigid panel.
