Abstract: The present invention provides an eye-controlled password input apparatus, which comprises a display device to display a password menu, an image capturing device to capture an user's eye region image, a memory unit to store at least one preset password and a corresponding account number, a control unit to generate the password menu according to the preset password, and an image processing unit. The image processing unit obtains a plurality of reference objects from the eye image so as to recognize the eye movement direction and to confirm password input. After input a character of the password, the display device generates another password selection menu for the user to input another password character until the password input program is completed.

Abstract: A gaze tracking password input method and a device utilizing the same wherein the method includes the following steps: picking up photo images of a person's eyes by a photographing unit which continually takes photo shots at a particular area as the person approaches to the photographing unit and his eye enters the particular area; transmitting the photo images taken at the particular area to an operation unit; setting a script associated with a particular point as a password; and then determining the person's gaze tracking direction which indicates the script to be input by the operation unit. The operation unit comparing the multiple input scripts with predetermined passwords, if the input scripts are matched with the predetermined passwords, then the person is officially authorized.

Abstract: A vehicular eye-controlled device having an illumination light source essentially includes a first body and a second body which are independent and separate. The first body has an electronic component disposed therein and required for operation and a photographic unit exposed therefrom for capturing an image of a driver. The second body is disposed in the vicinity of the first body and includes an illumination unit for providing illumination required for eye-controlled operation. The illumination unit and the photographic unit are separated by a distance of at least 5 cm.

Abstract: The present invention relates to an eye searching method and an eye state detection apparatus and an eye searching apparatus using the same. The method comprises the steps of: defining each center point of two nostrils from a face image; computing a distance D between the two center points of the two nostrils and a midpoint between the two center points of the two nostrils; determining a reference point that has a horizontal distance k1×D and a vertical distance k2×D spaced apart from the midpoint, wherein k1=1.6˜1.8, k2=1.6˜1.8; and defining a rectangle around the reference point as its center, wherein the rectangle has a width and a length greater than the width, and the rectangle surrounds the eye of the face image. Accordingly, the present invention can quickly and accurately find out a certain part of the eye from the face image.

Abstract: A lighting control system for controlling a luminaire includes detection module and a control unit. The detection module is configured to detect traffic flow of a road and ambient light along the road. The control unit coupled with the detection module is configured to receive a detection result of the detection module and generate a control signal according to the detection result and a preset data stored therein for controlling illumination of the luminaire.

Abstract: An eye-tracking method includes: acquiring an image of an eye of a user captured by an image-capturing module while the user is gazing at a gazing location on a screen module and a pair of light sources emit light toward the eye of the user; determining an angle and an area based on positions of a pupil and two reflected light spots on the eye of the user, wherein the angle and the area correspond to the gazing location; determining coordinates on the screen module based on the angle and the area, wherein the coordinates correspond to the gazing location; and performing an operation associated with the coordinates. An eye-tracking system for implementing the eye-tracking method is also disclosed. A correcting method and a correcting module for the eye-tracking system are further disclosed.

Abstract: An eye-tracking method includes acquiring an image of an eye of a user, identifying a pupil of and a reflected light spot on the eye from the acquired image, determining a distance of the reflected light spot from a reference point on the pupil and an angle of the reflected light spot from an axis passing through the reference point on the pupil, determining a gazing point based on the distance and the angle and a pre-established set of data, and performing an operation associated with the gazing point. A system for implementing the eye-tracking method is also disclosed.

Abstract: A differential gear transmission type work units positioning system includes a linking mechanism, which is formed of a compound gear, a fixed rack, a drive rack, a driven rack, a rail and a screw rod, and is coupled to a number of work units, for example, Charge-Coupled Device work units, pitch-adjustable material suction and feeding work units, or pitch-adjustable material carrying work units for controlling the positioning of the work units and moving the work units at an equal pitch, and a driving mechanism for driving the linking mechanism.

Abstract: A winding type flexible printed circuit board tape transferring system includes tape let-off wheel unit, a tape take-up wheel unit, two idle wheel units adapted to guide movement of the flexible printed circuit board tape from the tape let-off wheel unit to the tape take-up wheel unit, a tension control wheel unit adapted to control the tension of the flexible printed circuit board tape being transferred from the tape let-off wheel unit to the tape take-up wheel unit, and at least one work wheel unit adapted to rotate a respective rotary encoder upon movement of the flexible printed circuit board tape, enabling the rotary encoder to output a signal to a control unit indicative of the position of the flexible printed circuit board tape.
