PendingCN122093971AReduce unpredictable fluctuationsDetectable adjustment pathsElectrical apparatusEnergy saving control techniquesEnergy budgetLight equipment
This invention discloses an energy-saving control method and system for a portable lamp, relating to the field of portable lighting equipment control technology. The invention utilizes closed-loop control with a target current as the setpoint, combined with periodic sampling of the actual current and PWM duty cycle adjustment, to transform the light source output from nonlinear disturbances on the power supply side into a controlled current tracking process, reducing unpredictable fluctuations in output caused by voltage changes. Simultaneously, battery state parameters and expected task duration are incorporated into the available energy calculation, forming a time-sharing energy budget. This expands the lighting output from single-moment brightness control to cross-time period energy consumption allocation control. The planned curve allocates the target current in the time dimension, forming an energy consumption rhythm that matches the task duration.

Continuous zoom smart glasses with light blocking
This application relates to the field of smart glasses technology and discloses a light-blocking continuous zoom smart glasses, including smart zoom glasses and spectacle lenses. The spectacle lenses are installed inside the smart zoom glasses. A light-blocking mechanism is provided on the front of the smart zoom glasses, and a support mechanism is provided on the inner side of the smart zoom glasses. The light-blocking mechanism includes a micro motor, a connecting rod, a clip, and a sunshade lens. The sunshade lens is inserted into the inner side of the clip. A control switch is provided on the outer side of the smart zoom glasses for controlling the start and stop of the micro motor. With this light-blocking continuous zoom smart glasses, by adjusting the angle of the sunshade lens, when the sunshade lens rotates to the front of the spectacle lenses, the sunshade lens blocks the front of the spectacle lenses. This allows the smart zoom glasses to filter out some of the bright light during focusing, thereby reducing the brightness received by the user's eyes and allowing the user to see clearly, making the use of the smart zoom glasses safer.

Laminated glass, projection system, and vehicle
PendingCN122232269Aincrease overlapEasy to adjustWindowsWindscreensColor correctionProjection system
This application provides laminated glass, a projection system, and a vehicle. The laminated glass includes a first glass plate, an intermediate adhesive layer, a second glass plate, a functional layer, and an adjustment layer. This application achieves image clarity by setting a first wedge shape and defining a first preset range, ensuring that the reflected primary image and the reflected secondary image of the functional layer coincide. Furthermore, the reflective nature of the functional layer enhances brightness. The high degree of overlap between the reflected primary image and the reflected secondary image facilitates color correction of the superimposed image, resulting in a better color-shift-free display. Additionally, the adjustment layer significantly reduces the brightness of the reflected secondary image of the glass plate, even eliminating ghosting, thus avoiding image blurring caused by insufficient overlap between the reflected secondary image and the primary image. This results in a clear display image and improved driving safety.

A method and apparatus for accurately calculating the brightness value of a human face region
ActiveCN116668672BImprove recognition ratehigh speedCharacter and pattern recognitionTelevision systemsFacial regionExposure
This invention discloses a method for accurately calculating the brightness value of a facial region. The method analyzes the brightness histogram and calculates brightness constraints for the face bounding box identified by the algorithm. It performs secondary selection of the face for brightness statistics, reducing the impact of masks or other non-facial areas on the brightness calculation. By calculating mathematical features such as average brightness, variance, and median, it can preliminarily determine whether there are many areas in the image that do not meet facial attributes. By filtering the pixels of the region according to brightness constraints and removing overexposed and underexposed background pixels, the average skin tone brightness of the facial region can be more accurately obtained. This invention also provides a device for accurately calculating the brightness value of a facial region. This invention improves the facial brightness calculation method, reduces the deviation between the calculated facial brightness and the actual facial brightness, and solves problems such as repeated fluctuations or underexposure and overexposure in subsequent exposure adjustments.
