A multi-way circuit having a plurality of base modules may be used in multi-way schemes for lighting control devices. The multi-way circuit may operate with a controller and the base modules of a lighting control system to provide a fully functional, multi-way toggle circuit, even when the switches installed in the base module are not paired or in their off modes. The multi-way toggle circuit can be defined as follows: if any button in the circuit is pressed (indicating a desire to change the load state), then the load toggles its state between on and off.

A method and apparatus for human-machine interaction, a terminal, and a computer-readable storage medium are provided. The method for human-machine interaction of the present disclosure includes: receiving interaction information of a user acquired by a sensor, wherein the sensor includes a sensor that acquires the interaction information by means of a touch manner; determining a reply control signal corresponding to the interaction information, wherein the reply control signal includes a tactile reply control signal and a visual reply control signal; and generating a tactile reply response according to the tactile reply control signal, and generating a visual reply response according to the visual reply control signal, wherein the tactile reply response is used to provide the user with a response action for a tactile stimulus, and the visual reply response is used to provide the user with a visible response action.

The present disclosure provides an intelligent lighting control system. The lighting control system includes a base module including a base housing forming a well and including a first electrical connector positioned in the well. A depressible switch is housed in the well that includes a spring biasing the depressible switch into an extended position that opens an electrical circuit between the power terminal and the first electrical connector. The lighting control system also includes a light switch module configured for nesting, at least in part, in the well of the base module. The light switch module includes a module housing configured to press the depressible switch into a retracted position upon nesting in the well and thereby close the electrical circuit between the power terminal and the first electrical connector and release the depressible switch into the extended position when unnested from the well of the base module.

A keyboard and a key structure capable of displaying instant image thereof are provided. The key structure includes a display unit, a circuit membrane, an elastic member, a key seat, a first supporting frame, a second supporting frame, and a translucent keycap. The first supporting frame has two first arms and two axle portions. The ends of the first arms are slidably disposed on an accommodation portion of the key seat. The second supporting frame has two second arms and two linking holes. The ends of the second arms are pivotally connected to the accommodation portion. The linking hole is elongated-shaped. When the translucent keycap is not pressed, the axle portion abuts against one hole-end of the linking hole. When the translucent keycap is pressed, the axle portion abuts against another one hole-end of the linking hole.

A switch that is designed for use as an emergency shut off for heating, air conditioning (AC) systems or appliances is provided, but is certainly not limited to these specific applications and has applications in many other fields. The switch is configured with one or more indicators (visual and/or audible) configured to indicate when the switch has been manually turned off, even though power to the switch is still active. In this manner when the switch has been accidentally or inadvertently turned off by an unsuspecting user, they will be notified that the connected appliance (e.g. heating or AC system) has also been turned off.

When the translucent keycap is not pressed, the axle portion abuts against one hole-end of the linking hole. When the translucent keycap is pressed, the axle portion abuts against another one hole-end of the linking hole.

The present disclosure provides apparatuses and methods for bulb detection for a lighting control system. The apparatus includes a lighting control module configured to cause a transmission of a quantity of electrical energy to a lighting circuit of a light fixture electrically connected to the lighting control module. The apparatus includes a detector circuit positioned in the lighting control module. The detector circuit is configured to measure a response of the lighting circuit to the transmission of the quantity of electrical energy. The apparatus also includes a controller in electrical communication with the detector circuit. The controller is specially programmed to correlate the quantity of electrical energy transmitted to the lighting circuit to the response of the lighting circuit. The controller is further programmed to determine the bulb type of a bulb electrically coupled to the lighting circuit of the light fixture.

A silent input module includes a silent mouse device. The silent mouse device includes a casing, a silent switch and a control unit. The control unit is disposed within the casing and in communication with the silent switch. When the silent switch is triggered, the control unit generates a control signal, and a vision unit provides a vision feedback according to the control signal. A silent feedback unit is disposed within a computing device. The computing device is in communication with a silent mouse device. The computing device includes a processing unit. After a silent switch of the silent mouse device is triggered to generate a switching signal to the processing unit, the silent feedback unit allows a vision unit to provide a vision feedback.

A keyboard device includes a wiring board with plural key switches, plural key structures corresponding to the plural key switches, and an anti-ghosting unit. Each of the plural key structures includes a keycap, a scissors-type connecting element and a light-emitting element. The light-emitting element is located under the keycap. At least a part of the scissors-type connecting element is arranged between the keycap and the wiring board. The keycap is movable upwardly or downwardly relative to the wiring board. The anti-ghosting unit is disposed on the wiring board or electrically connected with the wiring board. The anti-ghosting unit is used for avoiding key conflict between at least two of the plural key structures.
