Abstract:
A module for data center is presented, which is used for heat sinking of a heat source. The module for data center includes a first chamber, a second chamber, and a heat pipe. The heat source is positioned in the first chamber. The second chamber is adjacent to the first chamber. In addition, the heat pipe has an evaporation end positioned inside the first chamber and a condensation end positioned inside the second chamber. The heat pipe absorbs the heat energy in the first chamber with the evaporation end, transfers the heat energy to the condensation end, and eliminates the heat energy with the condensation end.

Abstract:
A boot system of an electronic device includes a central processing unit (CPU), a NAND flash, a synchronous dynamic random access memory (SDRAM), and a pulse count unit. The NAND flash and the SDRAM are electronically connected with the CPU. The pulse count unit is electronically connected with the CPU and the NAND flash. The pulse count unit may initialize and enable the NAND flash. The CPU reads a pre-boot loader stored in the NAND flash and loads the pre-boot loader in the SDRAM. The CPU executes the pre-boot loader stored in the SDRAM to boot the electronic device.
Abstract:
An electronic device obtains a motion of a displaced object in two captured video frames utilizing phase correlation of the two frames. The device identifies magnitude of the motion and an area in a phase correlation surface corresponding to an area of the object, and accordingly determines if the motion is a qualified motion operable to trigger a gesture command of the device. The phase correlation surface is obtained from the phase correlation of the two frames.
Abstract:
A structure of heat dissipation of an electronic device includes at least one heat pipe and a cooler. The heat pipe has a condensation end and an evaporation end opposite to each other, and the evaporation end is disposed on a heat generating element of the electronic device. The cooler is disposed on a rack and has a chamber therein, and the chamber has an inner shell having a cooling fluid therein. When the electronic device is mounted in the rack, the condensation end of the heat pipe is inserted into the cooler and positioned into the inner shell. The evaporation end absorbs the heat energy of the heat generating element, and transfers the heat energy to the condensation end, such that the cooling fluid dissipates the heat energy of the condensation end.

Abstract:
An embedded system comprises a main chip generating a sleep signal, a network interface controller (MC) generating a wake-up signal, a microprogrammed control unit (MCU), a switch, and a power source. The MCU sends a closing signal upon receiving the wake-up signal and an opening signal upon receiving the sleep signal. The switch comprises a public terminal, a free terminal, and a control terminal. The free terminal connects to the main chip, the control terminal connects to the MCU, the public terminal connects to the free terminal upon receiving the closing signal, and the public terminal disconnects from the free terminal upon receiving the opening signal. The power source connects to the MC and the MCU to provide power, and further connects to the public terminal to provide power if the public terminal and the free terminal are connected, and stop power if disconnected.
Abstract:
A zoom lens and a zoom lens module are provided. The zoom lens is configured to form an image of an object at an object side onto an image plane at an image side. The zoom lens includes a first lens group, a second lens group, a third lens group and a fourth lens group disposed in sequence from the object side towards the image side. The refractive powers of the first lens group, the second lens group, and the third lens group are negative, positive, and negative, respectively. The zoom lens satisfies 1.90
