Qualcomm launched the drone reference platform Snapdragon Flight in September 2015, and in November the mainland company Da-Jiang InnovaTIons (DJI) launched an embedded computer for drones and NVIDIA launched For Tegra X1 chips and Jetson TX1 modules for UAV applications, DIGITIMES Research believes that the chip industry has taken a more serious look at the drone market.
Qualcomm advocates that the Snapdragon Flight platform can implement the smallest 4K video drone, while NVIDIA emphasizes the Tegra X1 chip and the Jetson TX1 module. It has powerful graphics image computing power and is beneficial to the visual recognition application of drones. Both companies have emphasized the image processing capabilities of the wafer.
While concentrating on visual image applications and powerful computing power, Qualcomm and NVIDIA also emphasize the shortness and lightness of the system board. Qualcomm claims to calculate per gram. The Snapdragon Flight platform has excellent computing power. NVIDIA also advertises the Jetson TX1 only business card. The size.
Qualcomm and NVIDIA UAVs have been adopted by system vendors. The difference is that Qualcomm's platform solution is the main control system in the UAV, initially appealing to the high-end consumer drone market, and NVIDIA's chip solution is regarded as The optional additional system does not affect the original drone design. It is still time to verify which route the high-order computing chip should use on the drone.

Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material
Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
