Abstract: A near infrared lens assembly includes a first lens, a second lens, a third lens and a fourth lens, all of which are arranged in sequence from an object side to an image side along an optical axis. The first lens is with positive refractive power and includes a convex surface facing the object side. The second lens is a convex-concave lens and includes a convex surface facing the object side and a concave surface facing the image side. The third lens is a concave-convex lens and includes a concave surface facing the object side and a convex surface facing the image side. The fourth lens is with negative refractive power and includes a concave surface facing the object side.

Abstract: Photothermal antibacterial material RMG is provided in the present invention, where R represents aldehyde, di-aldehyde or multi-aldehyde, M is magnetic material, and G is reduced graphene oxide. A method of synthesizing the abovementioned antibacterial material comprises of three steps. At first graphene oxide was synthesized, followed by simultaneous reduction and functionlization with MNPs and eventually an aldehyde is modified on magnetic material to yield magnetic G functionalized glutaraldehyde (RMG). We utilize the photothermal feature of graphene for antibacterial activity, in addition graphene was functionalized with aldehyde for capturing bacteria and with magnetic material to enhance a focusing of light irradiation. Moreover, the magnetic properties of material could help for reusability of antibacterial material.

Abstract: The present invention relates to an accurate impedance designing method for a circuit layout. On a printed circuit board, opening circuit for a soldering pad of a electric device and a signal wire of the device so as to form a non-electrical connection between the soldering pad and the signal wire, thus, the impedance of the soldering pad is not involved at a detecting point so as to enhance the accuracy of the current signal measuring.

Abstract: The present invention is to provide a voltage input circuit applied to a notebook computer, which includes a first voltage terminal for receiving and outputting voltage, a first protection loop connected to the first voltage terminal and a second voltage terminal, a second protection loop connected between the first protection loop and the second voltage terminal, and a discharge loop connected between the second protection loop and the second voltage terminal. When a short condition occurs in the notebook computer, the first protection loop electrically cuts the connection between the first and second voltage terminals and outputs voltage to the discharge loop through the second protection loop, so as to prevent circuits or electronic components in the notebook computer from being burned or damaged.

Abstract: A bus system having a transmission interface and a transmission control module built in a processor is provided. The transmission interface receives instruction signals output from the transmission control module and executes a corresponding data transmission process such that fast data transmission between storage unit of the processor and a host port interface (HPI) of a peripheral device may be fulfilled without an action of the processor, so as to avoid a waste of processor resources and an increase of production cost.
