"Programming with LabVIEW FPGA allows us to adjust the timing and power of each pulse to meet our dual requirements for high speed and high accuracy." - Michael Wiltberger, OpTIMedica CorporaTIon challenge: solution: Diabetic patients are prone to retinopathy, and more than 16% of diabetic patients develop retinopathy and eventually become blind. The traditional treatment of retinal diseases caused by diabetes has hardly progressed in the past 35 years. Photocoagulation therapy can improve the use of directional laser pulses to control the cutting of the marginal retina. Although this treatment can be extremely effective in preventing vision loss, it is very painful for patients and doctors. The so-called photocoagulation therapy is to block the microangioma and abnormal blood vessel leakage by aiming to emit laser pulses. Due to the complexity and sophistication of the procedure, this laser aiming launch has been manually controlled by doctors through joysticks and foot switches for nearly 35 years, and can only emit one 100 millisecond laser pulse at a time. The whole operation is a painful process for doctors and patients: the laser treatment device can only 'burn' one point at a time, and one eye needs to 'burn' 2000 points, so the whole treatment usually takes The eyes are divided into 4 quadrants, ie 4 courses, each time between 12 and 15 minutes. Once a week, the patient takes a month to complete the entire treatment process. At OpTIMedica, we design medical equipment to assist ophthalmologists in improving the course of retinopathy. We designed the PASCAL laser photocoagulation device to integrate the waveform scanning laser system to effectively improve treatment efficiency and reduce medical damage to patients. Considering the convenience of development and the hardware certainty that FPGA can bring about rapid retinal scanning, we chose LabVIEW software and R series hardware to replace the original custom hardware equipment, and designed and developed PASCAL photocoagulation therapeutic instrument (mode scanning laser instrument). . NI RIO devices are FPGA-based customizable hardware platforms that are suitable for high-speed, accurate, real-time acquisition and control tasks, so the most critical control system is the one that acts as the 'brain' of the entire laser treatment platform. Using a graphical system design, OpTIMedica quickly completed the design, build and release of the device for a successful demonstration of potential investors. Using an FPGA in this application also guarantees the flexibility of the hardware solution. It is not necessary to repeatedly check the same level of code in the process of applying for permission from the FDA (US Food and Drug Administration) as in a processor-based system. In addition, Optimedica uses a programmable chip instead of a fixed ASIC, saving 30% of development time. The revolutionary laser treatment platform based on NI RIO devices, through a high-precision, automated control system, assists the doctor in aiming to fire multiple laser pulses at a time in a certain pattern—that is, multiple 'burning' points at a time— Thereby speeding up the surgery and reducing the number of treatments. The control system of the new therapeutic device now automatically transmits up to 25 pulses of 10 milliseconds each time. In addition, the automatic transmission of multiple pulse waves can also ensure safety. The PASCAL system can greatly reduce the accidental risk of laser surgery on the fovea and reduce the loss of vision. From manual to automatic, from serial to parallel launch, the new laser treatment platform greatly improves the accuracy and safety of the procedure, reducing both the time of each treatment and the total number of sessions, not only reducing The pain of the patient also saves their time and money.

Create a controller for the latest PASCAL (Chip Scan Laser) laser coagulator with LabVIEW FPGA and intelligent data acquisition hardware. 
It is used in the mine where there is coal dust and methane but no explosion danger, for electric drive and lighting. This transformer is oil immersed. Its internal structure and working principle are the same as those of ordinary oil immersed power transformer. The main difference is the housing and the inlet and outlet devices.
The mining general transformer has a firm structure and low appearance. There is no oil conservator on the upper part of the transformer, and proper space is left on the oil level in the oil tank to prevent excessive pressure in the oil tank when the vent on the tank cover is blocked. The mechanical strength of the oil tank can withstand the pressure of 0.1 MPa without permanent deformation. The high and low voltage incoming and outgoing lines of the mining transformer are all cable junction boxes filled with insulating glue.
The capacity of mining general transformers is 50, 100, 180, 320 KVA, etc. Non excitation voltage regulation is set at the primary side of the transformer, and the voltage regulation range is ± 5%; Six terminals are led out from the secondary side coil, which can be Y/△ connected to obtain 690/400V or 1200/690V.
Mine flameproof transformer
It is used in places with explosion risk in mines. This type of transformer is mostly made of dry type, and its main structural feature is that all the joint surfaces of the box shell are made according to the requirements of explosion-proof, and can withstand the internal pressure of 0.8 MPa.
The capacity of dry-type transformer for mining is generally 4 KVA and 2.5 KVA, which are specially used to supply power for electric drill, lighting, signal and other equipment. Its incoming and outgoing lines are led out by cables through outlet sleeves. There are 380 V and 660 V voltages on the primary side; The secondary side voltage is generally 133 V.
Satons flameproof transformer with a capacity of more than 100 KVA is often combined with flameproof switch box to form a complete set of flameproof mobile substation. Its output voltages are 400V, 690V and 1200V to meet the needs of mine electrical equipment. In order to adapt to tunnel transportation, the transformer structure height should be low. In this way, the iron column diameter can be larger, and cold rolled silicon steel sheets are generally used. 100 KVA and above are usually Class H insulation.
