4 results about "Key light" patented technology

This invention discloses a digit counter based on key-based indicator lights and its counting method, belonging to the technical field of counting devices and training tools. The digit counter includes number keys (1-10), a number key 0, a flashing light key, a decimal point key, lights, a switch, and a control chip. Each number key has a light and a switch; the switch controls the lights of all number keys less than or equal to their number to illuminate, and the lights of number keys greater than their number to turn off. Number key 0 controls the power on / off, the flashing light key controls the flashing mode, and the decimal point key controls the decimal point light's on / off state. The control chip detects key presses and controls the lights' on / off state. Carry and borrow are achieved manually by adding or subtracting 1 from the higher digits, without automatic chip control. The counting method includes power on / off, manual counting, flashing light mode, carry, borrow, multi-digit flash reading training, sequential memory training, software simulation, and mental arithmetic training steps. This invention features a simple structure, convenient operation, quiet and portable design, and strong training appeal. It can replace traditional abacus and mental arithmetic training methods, reducing the learning curve and making it suitable for various scenarios such as mathematics teaching, intelligence training, concentration training, daily calculation, mental arithmetic training, and prevention and treatment of Alzheimer's disease.

1. Name of the product in this design: Graphical User Interface for Controlling Range Hoods in Electronic Devices. 2. Intended use of this design: for use in electronic devices. 3. The key design features of this product are the content of the graphical user interface on the screen. 4. The picture or photo that best illustrates the key design points: Design 1 front view. 5. Design 1 is designated as the basic design. 6. Purpose of the graphical user interface: When the range hood is powered on, as shown in the main view of Design 1, all indicator lights are on; when powered on, the screen automatically goes black to enter the power-off black screen state, as shown in the interface change state diagram of Design 1, at which time the power button is slightly lit; when the power button is clicked, the range hood enters the standby state, as shown in the interface change state diagram of Design 1. The range hood is in standby mode, which is the main view interface of Design 2; clicking the light button enters the lighting-on state, which is the interface change state diagram of Design 2, at which time the range hood light is turned on. The standby state of the range hood is shown in the main view interface of Design 3; the automatic cruise state is shown in the interface change diagram of Design 3 when the automatic button is pressed briefly in the standby state. The range hood is in standby mode, which is the main view interface of Design 4; clicking the high-speed button enters the high-speed mode, which is the interface change state diagram of Design 4. At this time, the high-speed button is fully lit and the fan is running at high speed. The range hood is in standby mode, which is the main view interface of Design 5; clicking the low speed button enters the low speed mode, which is the interface change state diagram of Design 5. At this time, the low speed button is fully lit and the fan is running at low speed. The range hood's standby state corresponds to the main view interface (Design 6). A short press of the "Smart Odor Removal" button enters the Smart Odor Removal preheating state (Design 6 interface change state diagram 1). At this time, the power button illuminates orange and displays a breathing effect, while the range hood activates air quality detection. If good air quality is detected (Design 6 interface change state diagram 2), the power button illuminates green, and the fan does not operate. If poor air quality is detected (Design 6 interface change state diagram 3), the power button illuminates yellow, and the fan operates at low speed. If extremely poor air quality is detected (Design 6 interface change state diagram 4), the power button illuminates red, and the fan operates at high speed. In both poor and extremely poor air quality states, when the range hood detects improved air quality, it returns to the good air quality state (Design 6 interface change state diagram 2). In the good air quality state, after 2 minutes, it enters a low-power state (Design 6 interface change state diagram 5). In the low-power state, the power button is half-lit, the Smart Odor Removal button is dimly lit, and the other buttons are off. The range hood is in standby mode, which is the main view interface of Design 7. Press and hold the "lock screen button" for 1.5 seconds to enter the lock screen mode, which is the interface change state diagram of Design 7. At this time, the lock screen button is fully lit. Press any button briefly, the buzzer will sound twice, and the lock screen button indicator light will flash twice.

The utility model discloses a portable tooth whitening instrument of high lumen brightness, aims at solving the problem of insufficient illumination brightness of the existing whitening instrument, uneven illumination leading to poor whitening effect. The whitening instrument includes a casing, LED lamp row, battery and the key light cup. Its technical core lies in: the light cup is the transparent curved surface structure of cover setting on LED lamp row, is equipped with the recess for accommodating LED lamp pearl on the back convex surface, and the back convex surface is densely covered with concave point and is electroplated with the light reflection film. The utility model discloses through this special optical structure, makes the light of LED emission after high -efficient diffuse reflection and lens focusing, improves about 20% illumination, forms the light beam of high brightness, high uniformity, can evenly irradiate on the tooth surface to improve the catalytic efficiency of whitening gel and the final whitening effect significantly.
