Abstract: A method for preventing theft of an electric vehicle includes steps (a) and (b). In step (a), when a switch detector detects that the state of a main switch is an OFF state, and when a rotation detector detects that a drive wheel is rotating, a controller is configured to count a time period of rotation of the drive wheel. In step (b), the controller is configured to enable a locking mechanism for locking the drive wheel from rotation when the time period counted by the controller reaches a preset time period.

Abstract: An eye module is provided. The eye module includes a casing, an eyeball and a first driving element. The eyeball having a surface is disposed in the casing. The first driving element leans against the surface and drives the eyeball to rotate by a first friction force generated by rotating the first driving element.

Abstract: An eye module at least including a body, a magnetic element, a casing and a plurality of magnet windings is provided. The body is a globe. The magnetic element is disposed on the body. The body is disposed in the casing in a rotatable manner. A plurality of magnet windings are disposed at the back of the body. The body is rotated by driving the magnet windings to function on the magnetic element.

Abstract: The invention discloses a device for animating facial expression. The device includes at least one resilient member and at least one actuator. The resilient member is regarded as a facial feature on a face, and the resilient member has a first end and a second end. The first end of the resilient member is rotatably and/or movably attached onto the face. The actuator is used for actuating the first end of the resilient member to rotate, so that the facial feature is capable of exhibiting various facial expressions on the face, wherein the facial feature can be eyebrow, upper eyelid, lower eyelid, upper lip or lower lip.

Abstract: A method for signal processing of a General-Purpose I/O (GPIO) interface is provided to have a data signal carried on a control signal. First, reset timing of the data signal to form a reset data signal. Then, have the reset data signal carried on the control signal.

Abstract: The present invention relates to a label device for optical discs, which is capable of being installed into an optical disc device to form an image thereon. The label device includes a label layer and an adhesive. The label layer has a bottom surface on which the adhesive is formed. The label layer is configured to form the image via a writing unit. The label layer further includes a substrate and a label film for forming the image thereon. The label device is attached to a base or an optical disc by the adhesive so as to be installed into the optical disc device. The optical disc device is then utilized to form the image on the label film.

Abstract: The present invention provides an optical disk and, more particularly, an optical disk including a data side and a label side. The data side has a first pregroove on which a plurality of first position marks are marked to provide an optical pickup unit with a basis for writing data onto the data side or reading data from the data side. In addition, the label side has a label layer and a second pregroove on which a plurality of second position marks are marked to provide the optical pickup unit with a basis for forming an image onto the label side.

Abstract: The present invention provides a reversible thermochromic optical disc capable of forming a pattern thereon by an optical pick-up unit of an optical disc drive. The reversible thermochromic optical disc includes a substrate and a reversible thermochromic dyestuff. The substrate has a label surface. The reversible thermochromic dyestuff coated on the label surface has a hysteresis characteristic upon change of a temperature, and changes between a colored state and a decolored state, wherein the color of the reversible thermochromic dyestuff responds to heat of a laser beam emitted by the optical pick-up unit to form the pattern.

Abstract: The invention pertains to an optical disc capable of storing the usage status of a label side of the optical disc. The optical disc includes a data side, the label side, and a plurality of partition marks. The data side is configured to read and write data thereon by utilizing an incident laser beam, and the label side is configured to form an image. The label side also has a plurality of partitions defined thereon. The partition marks are arranged on the label side and initially set in a first state. The partition marks are capable of converting from the first state into a second state. Each partition marks corresponds to one of the partitions. When the image is formed on the label side, the partition marks corresponding to the partitions where the image is formed are converted into the second state to indicate the usage status of the label side.

Abstract: The present invention provides a system for recording an image onto a label layer of an optical disc. The optical disc also includes a data layer on which a plurality of predetermined address codes is marked. The system essentially includes a multi-focal lens module for dividing a laser beam emitted by an optical pick-up unit into a first beam portion and a second beam portion. The first beam portion is focused on the data layer to locate a first position by retrieving the predetermined address codes. The second beam portion is focused on the label layer to record the image at a second position opposite to the first position.
