The invention relates to an eye protecting device against a computer. The eye protecting device consists of an outside protecting device and a lighting circuit, wherein the outside protecting device consists of corner frames, plat frames and elastic bands; the upper end and the lower end of each corner frame are respectively and fixedly connected with cylinders; the two corner frames are respectively arranged on the left side and the right side of a computer display; the two plat frames are respectively connected with the cylinders at the upper ends and the lower ends of the corner frames through the elastic bands; the two corner frames and the two flat frames are mounted at the periphery of the computer display. The lighting circuit consists of LED lamp bands, an LED lamp band brilliance control knob, an LED lamp band switch, a power input terminal and a wire, wherein the two lamp bands are respectively mounted on the inside surfaces of the two corner frames and the inside surfaces of the two plat frames; the LED lamp bands, the LED lamp band brilliance control knob, the LED lamp band switch and the power input terminal form the lighting circuit through the wire; the power input terminal can be connected with the computer through a USB interface. The eye protecting device eliminates the damage of light rays emitted by a computer backlight on eyes of a computer user, and better protects the eyes of the computer user.

The invention provides a double-insurance structure of a keyboard hot-pressing point, which comprises an upper layer circuit, a lower layer circuit, keyboard keys, a spell-out circuit and the hot-pressing point, wherein the upper layer circuit and the lower layer circuit are connected with each other through the keyboard keys; the lower layer circuit is connected with the spell-out circuit; and the upper layer circuit is connected with the spell-out circuit through the hot-pressing point and is also connected with the spell-out circuit through an in-parallel hot-pressing point. By the structure, a keyboard can be operated in a high-temperature environment for a long time and can still be operated normally after a hot-pressing overlap position is stretched, so that the service life of the keyboard can be prolonged to a great extent; simultaneously, production processes are not increased in the design, and the original production efficiency is not influenced, so that the structure is extremely suitable for a computer user who works under a high-temperature environment.

A system is disclosed in which a user's personal computer may access a variety of information regarding products and services, through a computer network, in real time. The computer network collects product/service information from various sources, such as gift stores, clothiers, computer dealers, etc. and formats the information in a recognizable manner to enable the information to be viewed by a user at the user's personal computer.
