The crowdfunding platform Kickstarter recently landed two wearables, the wearable led panel and the miniature camera.
First of all, this wearable LED panel project is called Fos. Its construction is very simple, just a fabric with Velcro and an LED panel on the surface. It's lighter than a golf ball and can be attached to clothes, backpacks, and anywhere the user wants. The Fos panel contains a microprocessor, flash memory and power supply, and the LCD panel can display both blue and white colors.
Flexible LED panel
Fos can get information from the user's smartphone and display an animated pattern. For example, runners can use it to show their heart rate and cyclists can show their speed.
After spending $149 (about RMB 912) to fund the project, supporters were able to get the first wearable LED panel when the Fos was released.
Another miniature camera, called ParaShoot, weighs only 36.8 grams and can be attached to a belt or helmet to record the day's experience. This camera is capable of shooting 720 thin and narrow frame design has become the mainstream of smart handheld devices. Taiwan Industrial Technology Institute and Japanese manufacturer Komori jointly published "Non-Yellow Roll-to-Roll Ultra-fine Line Printing Technology", which is global. For the first time, a narrow-frame thin touch module was developed with precision wire printing technology of less than 20 μm (micron). At present, he is discussing cooperation with Taiwan panel factory and system factory, hoping to continue the competitive advantage of Taiwan's touch industry.
Lin Quanneng, director of the Ministry of Economic Affairs of Taiwan, said that the Ministry of Economic Affairs is pushing the smart handheld device to plan for the next four years. In the past, ITRI accumulated a lot of roll-to-roll research and development energy, and established a complete roll-to-roll test production line. This technology will also be applied to O led lighting , next generation flexible circuit boards and other applications in the future.
At present, most manufacturers still use the yellow light etching process to make touch panels, which is not only complicated and costly. ITRI introduces precision wire printing technology into the touch panel process on roll-to-roll equipment and transmission technology, on ultra-thin substrates. Direct wire printing can replace the yellow etching process, as long as one device can replace the traditional pattern sputtering, coating to development, printing and etching seven machines. The material usage rate of the metal wire is also increased from 5% to 95%, and the process of the 4 to 5 layer of the touch panel is completed, which has the advantages of high efficiency, environmental protection, and substantial cost reduction.
Liu Junting, director of the Institute of Electro-optics of the Taiwan Industrial Technology Research Institute, said that the process published by the Institute of Secondary Engineering and Komori has reached 7μm, which is the same level as the yellow etching process, and saves time and costs. Tsutomu Niitsuma, the new wife of Komori, said that Taiwan is the leader in the touch industry, so he decided to come to Taiwan and ITRI to develop equipment to make technology come true. Among them, gravure printing patents are in Komori, and related patents such as roll-to-roll process and design are in Taiwan Industrial Technology Research Institute.
The field of view is 100%, built-in anti-shake function, microSD card slot, USB interface, WiFi, automatic recording and 700mAh battery.
Micro camera
Unlike other wearable cameras, Parashoot has a companion WP8, iOS and Android app that allows users to view and control the camera itself from their mobile phone.
Parashoot's fundraising goal is $30,000. The supporters who want to get the camera for the first time will need to spend $149 to fund the project. The delivery time of the equipment is scheduled for December this year.

Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
