Sight tracking method based on neural network head movement compensation

The invention discloses a sight tracking method based on neural network head movement compensation, and the method comprises the following steps of respectively placing two infrared sources on middle points of two side edges of a display screen, forming a bright spot image on the surfaces of human corneas after the two infrared sources are reflected by the human corneas, and enabling a dark pupil effect to occur in pupil images, and the method specifically comprises the following steps of statically calibrating a fixation point; compensating head movement; and calculating the fixation point by utilizing a static mapping module and a head movement compensation module to form a dynamic human eye fixation point matching module. Due to adoption of the scheme provided by the invention, requirements on hardware are low, only an ordinary camera and two infrared sources are needed, the restriction of a three-dimensional tracking method in which multiple cameras are needed can be changed, the system complexity and the needed computation volume can be greatly reduced, and the sight tracking instantaneity can be improved; and in addition, the head movement is allowed, direct application can be realized through one-step calibration, repeated calibration is avoided, and main defects of the two-dimensional calibration method are overcome.

Non-pneumatic wheel and wheel, suspension and tire used therein

InactiveUS20110248554A1Prevent tire blowoutReduce vehicle accidentRimsLeaf springsCornering forceBrake fade
Provided is a non-pneumatic wheel (100) for a vehicle, and a wheel (100), suspension (200; 200-1), and tire (300) used therein that are capable of ensuring driving stability because there is no air chamber between a wheel (100) and a tire (300) to blowout. They are also capable of ensuring good road holding, preventing standing waves, reducing brake fade and cornering force, providing good handling and ride comfort, staying quiet when rolling, and are economical and environmentally friendly. The non-pneumatic wheel (100) includes a wheel (100), a shock absorbing member (220; 220-1) coupled to an outer periphery of the wheel (100) and absorbing or attenuating noise and vibration due to external shock, a plurality of resilient members (230; 230-1; 230-2) arranged around and coupled to an outer periphery of the shock absorbing member (220; 220-1) in a radial direction and having a plurality of resilient rings (230-1a) that are resiliently deformed in response to an external force, resilient links (240) respectively coupled to the resilient rings (230-1a) to evenly transmit external shock to the resilient rings (230-1a), rail plates (270) to which sliders (261) formed at both ends of the resilient links (240) are slidably coupled, and a tire (300) having a plurality of coupling grooves (321) formed along an inner periphery such that the rail plates (270) are inserted into the coupling grooves (321).

Method of using touch module as game controller

The invention relates to a method of using a touch module as a game controller, which comprises a touchpad of a notebook computer and a touch screen of a mobile phone. The touch module can be switched between a mouse mode and a game mode, and in the game mode, the touch module can detect two types of movement of a finger in one position: A, point touch; and B, sliding a short distance in a specific direction to issue commands of a directional key or a functional key to a system. In the mode of A, e.g. point touch, the touch module is divided into 2-6 zones, and when detecting that the finger is in the mode of point touch and immediately leave the position along the vertical direction without displacement, the zone in which the finger is located can be single-clicked or double-clicked to judge the functional key selected by the user; in the mode of B, e.g. sliding a short distance in a specific direction, when detecting that the finger is in the sliding mode, the touch module compares a starting position of a first time (X1 and Y1) and a measured position of a second time (X2 and Y2) and calculates the sliding direction to judge the directional key, the functional key, the variable increase or decrease or the game controller selected by the user; and the touch module can issue more than two types of commands in one position through matching of the two modes. Therefore, when the invention is used, the touchpad of the notebook computer and the touch screen of the mobile phone can have the function of the game controller.

Wave saw blade

A saw blade for cutting hard workpieces, such as concrete or stone, characterized by improvement of the shape of a shank of the saw blade providing a plurality of cutting tips of the saw blade with a rotational force while the cutting tips are securely attached to the shank. The saw blade comprises a disc-shaped shank having an insertion hole formed at the center thereof, through which a rotating shaft of an electric-powered tool is inserted, and wave-shaped portions formed over a prescribed portion of the radius of the disc-shaped shank, and a plurality of cutting tips attached to the outer circumference of the shank for cutting a workpiece. The wave-shaped portions are spaced a prescribed distance from each other and alternately arranged on the front and rear surfaces of the disc-shaped shank. The prescribed portion of the radius of the disc-shaped shank is at a distance from the center of the insertion hole. The cutting tips contain particles of high hardness.
