A system and method for nighttime lighting control and danger monitoring and alarming are provided. The system includes a data acquisition system, an information processing system, and a terminal control system. The data acquisition system is configured to acquire video information in a room and a voice content of a person in the room, and transmit the video information and the voice content to the information processing system; the information processing system is configured to obtain voice command information based on the voice content and age information and safety state information of the person based on the video information, and transmit the voice command information, the age information and the safety state information to the terminal control system; and the terminal control system is configured to control a terminal lighting fixture, and perform capturing of an image of the person and perform voice alarming according to the safety state information.

Methods and systems are provided to generate metamerically matched illumination on a surgical site. The metamerically matched illumination may reduce or remove strobing effects associated with illumination devices during a surgery or surgical procedure. By metamerically matching illuminants in the illumination in combination with estimates of the human visual system, the illumination of the surgical site can visually appear to a user as a continuous white light, while maintaining distinct underlying spectra in the illumination. The light reflected by the surgical object may also be captured and metamerically matched, such that the reflected light appears as a single continuous color.

This disclosure provides methods, devices, and systems for controlling motion-activated switches. The present implementations more specifically relate to relay controller that prevent motion-activated switches from turning off devices associated with an environment in which people are present. In some aspects, a motion-activated switch may include a relay controller coupled to a motion sensor, a camera, and a relay. The motion sensor outputs a motion trigger to the relay controller responsive to detecting motion in an environment. The motion trigger may cause the relay controller to acquire one or more images of the environment, via the camera, and selectively toggle the relay based on the acquired images. For example, the relay controller may close the relay responsive to identifying an image that includes an object of interest or may open the relay controller may open the relay responsive to identifying an image that does not include an object of interest.

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.
