Without the help of a timer, how to ensure that the brushing time reaches the recommended 2 minutes? The people behind the smart toothbrush Beam Brush said that the average time for people to brush their teeth is only 46 seconds, but a simple timer can allow more than 50% of people to reach the recommended time of 2 minutes. The team's Bluetooth toothbrush made its debut at CES a year ago and was approved by the FDA in June. The official price last week was $ 49.99. In addition to a sensor that tracks the frequency and time of brushing your teeth, it also has a timer that can play 2 minutes of music.
With a button on the handle of the toothbrush, users can also synchronize the data to the matching application and send it to the dentist.
Beam Technologies, from Louisville, Kentucky, even thought of an actual reward program, such as brushing your teeth at least twice a day for at least 2 minutes each time.
LED PCB
As printed circuit board technology has continued to evolve, it has paved the way for the creation of a host of exciting product innovations. A prime example is the development of the PCB for LED lighting. The LED is soldered to the circuit board and features a chip that produces the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip.
An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means. Consequently, metal core PCBs are frequently chosen for LED application due to their enhanced ability to dissipate heat. Aluminum in particular is often used to manufacture circuit boards for LED lights. The Aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional Rigid PCB.
PCB LED Applications
PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. Examples include Automotive headlights, Airport runway landing lights, Lighting used in military field applications, Street lighting, Highway tunnel lighting, Photovoltaic (solar) lighting, Flashlights and lanterns, Traffic and signal lighting, Lighting in hospital operating rooms, High growth plant lighting and many others.
