Total Solution
SD 4.1 Family
To meet the ever increasing data transfer rate in high end applications, such as professional broadcasting transmission or advanced high resolution display, the SD 4.1 specification calls out the maximum performance of 1.56 Gbps at UHS-II full duplex mode per lane or half duplex UHS-II at 3.16 Gbps. In real applications, due to the system overhead and different SD 4.1 device controller designs, the actual measured performance can vary dramatically from system to system. With the newly introduced ADMA 3, the OS driver is now able to issue multiple read or multiple write commands at once, without having to wait for the SD controller to complete one command at a time. Once the SD host controller has collected multiple commands, it will then manage and complete them without intervention from the host software drive. Thus, the UHS-II 1.56 Gbps interface can be more effectively utilized and maximize the system throughput. This feature can be very useful when running multithreaded applications where multiple applications are constantly updating their status or swapping their contents by writing or reading small chunk of data to or from the memory card.

LV Iron Core Harmonic Filters
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

Automatic Total Nitrogen/Phosphorus Monitoring
TPNA-500
More than 10 years have passed since the 5th Water Use Regulation was enforced in 2001. From the perspective on preservation of ambient water quality, it has become a matter of course for companies to be compliant with regulations and observe corporate compliance. Total nitrogen and total phosphorus monitoring in the future has the potential to lead to proactive enhancement of corporate value, in addition to compliance with regulations. While we propose technological innovations and improvements and LCC*1 reductions, we will pursue the future where regulations are strictly observed and corporate value is improved through monitoring.
