The introduction of wireless mouse
Currently widely used wireless mouse uses a battery to supply power. Replace of the battery and brings inconvenience to the users. This paper presents a suitable for wireless mouse contactless power supply circuit, which comprises a contactless power supply of the primary circuit and the secondary circuit of 2 parts. Power supply device using USB power supply, voltage of 5 V, the self-excited oscillation circuit generates about 138 kHz high frequency oscillation voltage. The wireless mouse manufacturer will develop this technology all the time. The mouse pad built-in contactless coupling the primary coil carrying current output. Wireless mouse with built-in secondary current-carrying coil adopts contactless inductive coupling mode for obtaining electric energy, by the voltage integration chip to form a voltage regulating circuit, load voltage of 3.1V.
The use of the wireless mouse
The mouse is the most commonly used computer input device, along with PDA, notebook, wearable computer and portable devices such as pop, traditional mouse has been unable to meet the requirements for mobile office. The existing roller or photoelectric mouse needs a flat work surface, and its size is relatively large. The wireless mouse based on micro accelerometer is complete without this limitation, it can take one's ease in moving air to control computer; can be made very small, easy to carry, can be flexibly used in various occasions, such as: can be made for the disabled head wearing type mouse, for speakers to use mobile mouse.
The working principle of OEM mouse
Mouse according to their working principle can be divided into mechanical type and photoelectric type two, the most common is the mechanical mouse. Now the mechanical mouse is actually OEM mouse, the roller mechanical rotation is converted into an optical signal, and then converted into electrical signal. Roller type mouse is on the wheel drive X and Y axis on a decoding wheel to rotate, to sense the change of displacement of mouse; optical mouse is a self-contained light source of the photoelectric sensor, follow the movement of the mouse continuous recording of it through the surface of the "snapshot", these snapshots (frame) with certain frequency, size and resolution, and photoelectric mouse -- the core of DSP by comparing the differences between these snapshots to identify the moving direction and displacement, and the displacement of the information to be encoded real-time transmitted to the host computer.

This can be a good information especially to those who does not know yet the thing to consider when buying a wireless mouse for their PC. Technically, the wireless mouse is more efficient in its use because it is easy to handle and comfortable to use. A few tips on your choices on the wireless mouse is the Logitech G602, where it has a great features in accessing your device in an efficient way. The controls are easy to use and the key features are more ideal compared to the other mouse brand.
