Epistar (Crystal) filed a patent infringement lawsuit against Adamax (sold under the Newhouse Lighting brand) in the US District Court for the Northern California on August 30, 2016.
In its complaint, Jingdian pointed out that Newhouse Lighting products infringed six patents on crystal power and applied to the court to issue an injunction prohibiting Adamax from continuing to sell infringing Newhouse Lighting products.
In the complaint, Jingdian pointed out that Newhouse Lighting filament bulbs, for example, dimmable candle-type 3.5-watt LED retro-style Edison filament lamps, infringe many US patents on crystal power, including patent number 6,346,771, the title of the invention "high-efficiency LED lights", Patent No. 7,489,068, the title of the invention "Light Emitting Diode Device", Patent No. 7,560,738, the title of the invention "LED array with a bonding layer", Patent No. 8,240,881, the title of the invention "Package Structure of Light Emitting Diode", Patent No. 8,791,467, the name of the invention "Glowing Diode and its manufacturing method", Patent No. 9,065,022, the title of the invention "lighting device".
Jingdian invests huge amounts of money each year in the research and development of LED technology, and has obtained more than 4,000 patents and applications. These investments have laid the technical foundation for LED filaments and benefited the world in a variety of related products. Crystal Power continues to invest in research and development to provide the most advanced products and solutions for growing global LED users.
Jingdian sued Adama to ensure its R&D investment and patent rights were not violated.

Quick delivery
High performance
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.
