   For Light Sleepers
   Millions of people have trouble falling asleep each night，which is why LightSleeper was created.
   Developed in the United Kingdom，LightSleeper's makers say it can help a person fall asleep and also help a person fall back to sleep after waking up in the middle of the night.
   LightSleeper works by projecting （投射） a light onto the ceiling while the person is lying down.The idea is to watch the light，because the light moving in a circle has a relaxing effect.
   One of the advantages of the product is that it won't disturb other people in the room.The product can be easily moved and will switch itself off after 30 minutes to save power.
   Stop the Snoring （打鼾）
   Here's a new product designed to slow down the frequency and level of your snoring.The Snore Stopper has a sensitive instrument that will detect when you're snoring.Once it does that，it will send a very mild electronic signal to your wrist.This consequently changes your sleeping position to stop you from snoring.The Snore Stopper won't cause any damage to your body.
   Get Your True Colors
   Photoshop features a pen that will copy the color settings of what you are monitoring on screen to use as a color in your program.Now an offline product allows you to pick a color when not using the computer software.
   The Color Picker is a concept pen.After placing the pen against an object，the user just presses the scan button.Color sensors （感应器） inside the pen send information to a box，which then mixes red，green and blue to produce the desired ink color.
   Keep It Fresh
   More high technology products are showing up in the kitchen.A new Bagel dome （圆顶形物） advertises that it will keep your baked goods fresher for longer periods of time.The product，which is able to remove air，works for bread rolls，cakes and other perishables.To use it，you just push a button at the top.
