The present invention provides a backlight keyboard with a backlight adjusting function, a backlight adjusting system and a backlight adjusting method. The backlight keyboard includes plural keys and a backlight module. The backlight module includes a light guide plate and plural light-emitting elements. The backlight adjusting method includes the following steps. Firstly, the plural light-emitting elements emit light beams, so that plural backlight zones corresponding to the plural keys are formed on the light guide plate. Then, respective luminance values of the plural backlight zones are detected. Then, an overall average luminance value of the plural backlight zones is calculated. If a preset criterion is satisfied, brightness levels of the light-emitting elements corresponding to the backlight zones are adjusted according to the luminance value of the backlight zones and the overall average luminance value.

An information display method for a computer having a keyboard. The method includes selecting a first system information among a plurality of system information, wherein the system information is configured to respectively indicate statuses of a plurality of devices of the computer; selecting a first display pattern among a plurality of display patterns according to the first system information; selecting a first keyboard region for applying the first display pattern; and showing the first system information in real-time by a plurality of first buttons corresponding to the first keyboard region of the keyboard according to the selected first display pattern, the first keyboard region and the first system information.

A key module includes a circuit assembly, a support assembly and a display assembly. The support assembly is movably disposed on the circuit assembly. The display assembly includes a digital display unit. The digital display unit is supported on the circuit assembly by the support assembly, and the digital display unit is electrically connected to the circuit assembly.

A miniature circuit breaker with quick current breaking capability which includes a miniature circuit breaker body, a current transformer CT1, a zero-sequence current transformer CT2 and a smart controller module. The miniature circuit breaker body is internally provided with a main arc extinguishing chamber, a fixed contact, a movable contact, a tripping mechanism, and a magnetic tripping push rod. The tripping mechanism includes a lock catch, a movable contact rocker arm, a jump pin, a connecting rod, and a tension spring. A rotated-hinge repulsive force structure is applied between the fixed contact and the movable contact. The tripping mechanism is further provided with a torsional spring to press the movable contact close to the fixed contact. A shunt tripping device controlling the miniature circuit breaker switch to be turned off is arranged in the smart controller module.

The present invention relates to a lighting device for a button, in which light incident into a light guide is prevented from leaking to a spacing clearance between a button unit and a light guide by a reflection layer, thereby enabling a lighting through the light guide to shine cleanly and uniformly to the outside.

The present application includes an automation control device with a control panel, the control panel comprising at least one button with specified control function; and at least one luminous element located adjacent to the at least one button; wherein the at least one button is operable in a locked mode and a standby mode; in the locked mode, the press on the button would not trigger the specified control function of the button but would light up the at least one luminous element and switch the button into the standby mode; and in the standby mode, the at least one luminous element keeps in lighting, and the press on the button would trigger the specified control function of the button. The automation device is adapted for safe and correct operation in dim or dark environment.

Systems, devices, and methods described herein provide an input device having keys operatively coupled with light devices that emit light out of the keys. The input device is associated with different modes of operation. The light devices emit the light out of the keys responsive to a selected mode of operation being a first mode of operation. The light devices stop emitting the light out of the keys responsive to the selected mode of operation being a different, second mode of operation. The light devices are activated to indicate the selected mode of operation. One or more processors perform first functions associated with the keys during the first mode of operation and perform different, second functions associated with the same keys during the second mode of operation.
