According to Isao Echizen, a professor at the National Institute of Information Research in Japan, the "privacy-protected" lens uses 11 LEDs in the near-infrared band. When the wearer is photographed, they will emit near-infrared rays that are invisible to the naked eye to the camera of the Google glasses, causing the camera to be unclear due to excessive light, and thus unable to recognize the face.
He pointed out that wearing ordinary sunglasses does not prevent the face recognition function of Google glasses, because the facial features of the person include other parts such as eyebrows and nose, and only cover the eyes and escape the misfortune of the face recognition by smart devices such as Google glasses. .
Fiber Optic Adapter are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. People sometimes also name them to be mating sleeves and hybrid adaptors, mating sleeves means this fiber optic adapter is used to connect the same type fiber optic connectors, while hybrid adaptors are the fiber optic adaptor types used to connect different kinds of fiber optic connectors. YLTelecom`s fiber adapter provide reliable solution for fiber connections, single mode fiber optic adaptors and multimode fiber optic adaptors available on request. We adopt high quality raw materials and make these fiber optic adapters strictly according to international standard, this makes our fiber optic adaptors with high performance.
Fiber Optic Adapters FC, SC, ST, LC, MT-RJ, MU, E2000, FC/APC, SC/APC, LC/APC, E2000/APC, Simplex, Duplex, Quad, mating sleeves, hybrid fiber optic adapters, Single mode fiber optic adapters, multimode fiber optic adapters are all available.
Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).
When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber).
Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called "hybrid", accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.
