In order to provide users/customers
more benefits and peace of mind, especially for wireless
input devices, ATLab has developed five proprietary technologies
for power saving.
Eye Protection (EP) Technology
Eye protection (EP) is an ATLab¡¯s patented technology and it turns off the light source and/or reduces its power to minimum when user lifts the mouse off the surface. This technology not only minimizes the power consumption, but also protects user¡¯s eyes from the potentially harmful or at least dazzling light source such as LED (Light-Emitting-Diode) and laser.
Operating principle: the device detects the brightness of the environment light; if the brightness is above a set threshold, then the device turns the light source (LED/Laser) off; if the brightness is below a set threshold but above complete darkness, the light source turns on and off rapidly (blinking) with much reduced power to check the brightness of the environment.
This technology can also work as an optical touch switch for mobile applications. Applying the fingertip input device in a cellular phone, the device turns on only when the user put his/her finger on the input device.
Touch-On Sensing Technology
Using DCC (Digital Contact Controller), ATLab¡¯s another breakthrough technology, one can enable/disable the input device by putting one¡¯s hand on/off the device, respectively. The motion state of the mouse can be effectively controlled so that power consumption when not used is minimized.
DCC also makes it possible to implement buttons and scrolls electronically, replacing current mechanical parts.
Smart Image Enhancement (SIE)
By spreading the pixel distribution after capturing the images of the surface, one can achieve better performance with lower lighting power.
Smart Light (Self-Adaptive Power Saving)
Smart Light (Self-adaptive power saving (SAPS)) is another patented technology of ATLab, which controls the current consumption of the light source depending on the surface color, regardless of the movement speed of the input device. That is, more power on darker surface and less power on brighter surface.
Note that since ATLab not only uses lower clock speed (6MHz) than the leading company (18MHz), but also utilizes full search algorithm for navigation rather than neighborhood search used in the leading company, ATLab¡¯s navigation engine inherently uses less power than the leading company.
Smart Search
ATLab's navigation engine not only uses full search algorithm, but also uses variable search window sizes depending on the surface color (Smart Search), and hence ATLab can further reduce the power consumption by combining both Smart Search and Smart Light. Again note, that leading company's method depends on the moving speed, whereas ATLab's technology is nothing to do with the speed.
