Abstract: A semiconductor package including one or more dam structures and the method of forming are provided. A semiconductor package may include an interposer, a semiconductor die bonded to a first side of the interposer, an encapsulant on the first side of the interposer encircling the semiconductor die, a substrate bonded to the a second side of the interposer, an underfill between the interposer and the substrate, and one or more of dam structures on the substrate. The one or more dam structures may be disposed adjacent respective corners of the interposer and may be in direct contact with the underfill. The coefficient of thermal expansion of the one or more of dam structures may be smaller than the coefficient of thermal expansion of the underfill.

Abstract: This disclosure provides a smart lighting apparatus. The lighting device includes a power input device and an insertion slot. The power input device is electrically connected to a light source, and the insertion slot is installed between the light source and the power input device for receiving the smart card to manage the lighting device. The smart card has a power source and an ecosystem dimming device electrically connected with to the power source. The ecosystem dimming device controls the luminance of the light source with power-saving efficiency.

Abstract: An LED lighting device is provided. The LED lighting device includes a processing unit, a sensor, a MOSFET, and an LED. When the sensor detects a frequency or voltage fluctuation, the processing unit modulates the duty cycle of the MOSFET to reduce the energy consumption of the LED light device and improve the efficiency of luminance of the LED lighting device.

Abstract: An anti-counterfeiting electronic device includes a function component assigned with an identification code ID and a processor. The processor generates a random code K1 and transmits the random code K1 to the function component; the function component encrypts the random code K1 and the identification code ID to generate a key ID1. The processor further obtains the key ID1 from the function component and decrypts the key ID1 to generate an identification code ID2, and determines whether the identification code ID2 is the same as the ID and executes the system login command if the identification code ID2 is the same as the identification code ID. An anti-counterfeiting method is also provided.

Abstract: An electronic device includes an input unit, a memory, a page flipping control unit, a buffer, a display, a processor and a switching unit. The input unit generates flipping commands in response to operations of a user. The memory stores a document. The processor displays the document in response to a document opening operation of the user, retrieves a predetermined page range of pages of the document from the memory, and stores the retrieved pages of the document in the buffer. The page flipping control unit receives the flipping commands, accesses the buffer, and flips pages on the display. The switching unit is connected to the memory, the display, and the buffer, and establishes a connection between the display, the buffer and the processor or establishes a connection between the display, the buffer, and the page flipping control unit under control of the processor.

Abstract: An electronic device with a sleep mode includes a CPU and a monitoring unit. The monitoring unit includes a testing module, a storage module, a comparing module, and a signal generating module. The CPU falls into standby mode when the electronic device is in the sleep mode. When the comparing module determines any one of one or more parameters of a battery which supplies power to the electronic device measured by the testing module is not within a corresponding predetermined range stored in the storage module, the signal generating module generates signals to awake the CPU. The awaked CPU executes protection operation to protect the electronic device. A related method is also provided.
