The present invention refers to a method for operating an active input element and a corresponding input element, input arrangement and computer program product, comprising the steps: a) set value C of clock counter to 0 (S2); b) increase value C of clock counter by 1 and shift data in shift register (5) by one Bit, when detecting a clock information (S3); c) compare (S4) value C of clock counter with a cycle length CLL, and return to step b) if comparison result is negative or proceed to step d) if comparison result is positive; d) read data (D.sub.FIFO) from shift register (S5); e) compare (S6) said read data (D.sub.FIFO) from shift register (5) with predetermined first data value (Dl), and proceed to step f) if comparison result is positive or proceed to step a) if comparison result is negative; f) write data (D.sub.IE) derived from analog input device (S) into shift register (S7) and return to step a).

In embodiments, a method and system is provided for streaming lighting effect data wirelessly to a peripheral input device in lighting effect arrays. A current lighting effect array is compared to a previous lighting effect array, and compression is applied to one or more zones of light emitters in the lighting effect array.

Techniques and devices provide backlighting for keys of a keyboard or keypad.

A luminous press key module includes a bottom plate, a keycap, a membrane circuit board, and one or more micro LEDs. The keycap is installed above the bottom plate, the membrane circuit board is installed between the bottom plate and the keycap, and the micro LED is installed and electrically coupled to the membrane circuit board and arranged corresponding to the keycap. The micro LED can be installed on the membrane circuit board directly to omit the component of the conventional light guide plate, so as to realize a light, thin, short and compact design of the luminous press key module.

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 illuminated keyboard is a backlit keyboard. The illuminated keyboard comprises a keyboard and a switching network that generates the back lit illumination of the keyboard. The switching network divides the keyboard in to a plurality of zone displays. Each of the plurality of zone displays is used to illuminate a region of the keyboard. Each of the plurality of zone displays is independently controlled. Each of the plurality of zone displays further comprises a plurality of LEDs. Each LED contained within the plurality of LEDs is independently controlled and illuminated. Each LED selected from the plurality of LEDs is differentiated from the LEDs remaining within the plurality of LEDs by the illumination color of the selected LED. The illuminated keyboard comprises a keyboard, a switching network, and a network controller. In one potential embodiment of the disclosure, the illuminated keyboard is remote controlled.

An intelligent hybrid touch display device, including: a touch display unit; a rotary mechanical switch, being integrated with the touch display unit in a body; and a control unit, located in the body and including: a first interface for driving the touch display unit; a second interface coupled with the rotary mechanical switch; a touch and switch detection unit coupled with the first interface and the second interface; a transmission interface for communicating with at least one external device; and a processor and an operating system stored in a memory, the processor being coupled with the touch and switch detection unit and the transmission interface, and being used for executing a control program with a support of the operating system, so that the touch display unit and the rotary mechanical switch can cooperate to provide a hybrid operation for selecting, changing or activating function options.

The disclosure discloses a keyboard key structure. The keyboard key structure includes a switch circuit board, a first luminescent circuit layer, a switch element, and a keycap. The first luminescent circuit layer is disposed on the switch circuit board, and includes a plurality of miniature light emitting diodes. The switch element passes through the first luminescent circuit layer and is configured to contact the switch circuit board. Two of the plurality of miniature light emitting diodes are respectively located on two opposite sides of the switch element. The keycap is connected to the switch element and covers the plurality of miniature light emitting diodes. The keycap further has at least one light transmissive portion.

In embodiments, a method and system is provided for streaming lighting effect data wirelessly to a peripheral input device in lighting effect arrays. A current lighting effect array is compared to a previous lighting effect array, and compression is applied to one or more zones of light emitters in the lighting effect array.

The present invention relates to a switching device having programmable functionality markings. The switching device has: a switch, a functionality marking programmer, a functionality marking display, and a control module. The switch is used to control power supply to an electrical appliance. The functionality marking programmer allows a user to designate the switch to a specific functionality with a corresponding functionality marking. The functionality marking display displays the functionality marking programmed by the functionality marking programmer. The control module includes a processor and a memory. The memory stores computer executable instructions. When executed at the processor, the computer executable instructions is configured to: receive functionality marking programming instructions from the user via the functionality marking programmer, designate the functionality of at least one switch with a functionality marking according to the functionality marking programming instructions received, and display the programmed functionality marking of the switch via the functionality marking display.
