A fingerprint or palmprint or handprint or soleprint sensor is a transducer that converts the ridge valley structure of a persons hand or foot sole to an electrical signal. Generally, the sensor reads the difference of pressure, temperature, light, electrical capacity, or other kinds of energies which are measured between the ridges and the valleys. Then, this difference is converted into an electrical digital signal that is encoded as an image representing the ridge valley pattern. Different technologies can be applied to achieve this conversion and each of them brings advantages and disadvantages. It is important to highlight that the output signal is a representation of the real world ridge valley pattern. Hence, if F is a ridge valley pattern of a real world fingertip and s is the transfer function of a device, the output signal is F. Live Tv Viewer 1 03 Full Movies.
