Samsung Working On three-D Facial Recognition
A new record says Samsung is operating in the three-D era to compete with Apple’s Face ID. According to news from 9to5mac, a piece of writing in The Korea Herald said the employer had requested Israeli startup Mantis Vision to paintings at the technology. Samsung released face reputation before Apple, but the tech became most effective in 2D — and maybe without problems misled using both photographs and videos. In reality, it’s not safe enough for use in secure applications, inclusive of payments. The article explained that Mantis is reportedly operating on the generation of Samsung’s subsequent era Galaxy S smartphone, which is proper now being known as the Galaxy S10. Another outlet mentioned Mantis is working with digicam module company Namuga to combine three-D sensing software right into a digicam module.

Nama components three-D modules for Intel real sense cameras utilized in laptops and capsules like ASUS, HP, Dell, Lenovo, and Acer. This is not the handiest new generation on which Samsung is operating. Earlier this yr, it becomes pronounced that the organization had carried out a patent protecting a device authentication technique that might measure a person’s blood stress to affirm their identification.
The patent states that “the arterial conduction paths of various users are nearly in no way identical,” which might update passwords and PIN codes. The belief is that blood pressure authentication, partnered with fingerprint scanning, should make it tougher for hackers to steal facts on a person’s mobile tool.
And, in 2016, the corporation posted a patent for a sensor on the wrist that might be capable of “examine” a person’s veins to confirm identification. The sensor takes a picture of the wrist and different traits and uses it to confirm the user by using comparing it to a vein photo in its memory. It can also read and verify a user’s pulse.
However, there’s no assurance that Samsung will ever truly release both of this technology. One of the not unusual problems in Samsung 153v LCD Monitor changed into display dim. If you get towards the screen and examine the show under dark surroundings, you should see it, but it became very dim. If you press the front panel button, the on-display screen show (OSD) might regard this proof that the mainboard, motive force board, and LCD panel are operating, and the trouble is in the inverter board. The function of the inverter board is to generate an ac wave from dc voltage to strengthen up the lamps, which were placed at the pinnacle and bottom of the LCD Monitor. If the inverter board has issues, it will not light up the lamps, and what you can see only a dim display.
I nonetheless may want to consider after I first encountered such issues long-term in the past, and due to lack of information, I could not solve it. I did call up my restore pals to request the solution; however, nobody could give me a solution. Even if you surf the internet for “Samsung 153V LCD Monitor dim show repair”, you will not find it. Due to this, I must do my personal studies to find the solution, and I’ve never surrendered. Winston Churchill once said, “Never, in no way, in no way give up.” So I’m releasing the answer handiest to my dependable members or subscribers most effective-thanks on your aid.
Let’s start now! Once the cover and the inner aluminum casing have been opened, I saw bulged filter capacitors at the second facet of the transfer mode electricity supply. The price turned into 470 and 1000 microfarad 25 volts. I saw 4 extra electrolytic capacitors positioned on the inverter board have changed color, and the value changed to forty-seven microfarads 25 volts. Browsing via the complete board with my ESR meter, I located another defective capacitor (220 of 25 volts) which became close to the fuse (3amp). Since this capacitor became positioned at the identical line with the fuse, I presumed that the fuse might also deliver. True enough, checking the fuse with an ohmmeter revealed that it has an open circuit.
Now, the real problem confronted by many digital repairers who offers this version became, after changing all the additives above, the LCD Monitor still might no longer paintings-it is nonetheless dim! First, you need to ask yourself why the fuse is blown? Could or not it’s due to the defective capacitors or something shorted past the fuse line? The nearest circuit to the fuse changed into the start circuit that consisted of a couple of NPN and PNP digital transistors (4k7 +4k7 resistor constructed into the transistor). Some other LCD screens designed used the mixture of C945 and A733 in begin circuit. By the manner, the element wide variety of Samsung 153V start circuit transistors had been the A6J (PNP digital transistor) and the A8J (NPN digital transistor) as shown in the photo.
Sometimes handiest transistors have issues (shorted) that brought on the fuse to blow; however, both digital transistors are tested inside the above case. Since both transistors were operating, the awareness needs to be in the 4 ic’s that drive the high voltage transformers because the 12 volts voltage supplies to every one of these pics. These four ic’s have many element numbers and the most commonplace one which the manufacturer used to become 4532m. Some boards used the AD4E10 and BBD3N13 component variety. At the moment, it is quite tough to get the datasheet or technical specification for this range, even from the web seek.
Do you recognize what’s inside those IC’s? It is absolutely a couple of P-channel and an N-channel MOSFET built into it. And do you know that it can be check with a meter? Yes, if you use the Peak atlas element analyzer, it might spark off to your result. From the result, what you get is N channel FET placed at pin 1 (source), pin 2 (gate), pin 7 & 8 (drain and both pins joint collectively internally). As for P channel FET, pin 3 (supply), pin 4 (gate), and pin 5 & 6 (drain and both pins joint internally). From the above check, I determined two of those ic’s have shorted. Replacing those two shorted IC with the capacitors and fuse put the LCD Monitor lower back into existence!
