According to foreign media reports, the Israel Defense Forces is developing a wearable bracelet, which is mainly used to monitor soldiers' pulse, blood pressure and other vital signs, to identify the extent of soldiers injured and injured in the war, so that the hospital can reach the wounded Receive data before.
At present, the application of wearable devices in the medical field is gradually expanding. In addition to being able to detect and monitor changes in human body values, smart wearable devices have recently entered the field of medical treatment, and Kumamoto University has developed a wearable belt for treating type 2 diabetes. According to Kalorama InforMATion, a market research organization in the medical field, the global market for wearable medical devices will exceed $13.2 billion in 2016. KaloramaInformation said that the market focus of wearable medical devices has shifted from fitness and improving human life to diagnostic monitoring, and it is expected that the future will be a major step in disease treatment.
At present, domestic companies are actively deploying in various fields to develop various types of mobile medical applications.
4G Mini Camera Structural components
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
