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.

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.

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.

An apparatus and a method for changing optical tweezers are provided. The apparatus includes a diffractive optical element (DOE), a mask unit and an objective lens. The DOE includes a plurality of phase delay patterns. The mask unit includes a plurality of mask patterns that correspond to the phase delay patterns, respectively, wherein at least a portion of the mask patterns are complementary. A laser beam passing through each phase diffractive pattern correspondingly passes through each mask pattern to generate a compound diffractive pattern. The objective lens receives the compound diffractive pattern and focuses it on an examining object to form an optical tweezers.

An apparatus of generating an optical tweezers with momentum and method thereof and an optical tweezers photo-image for guiding particles are provided. The apparatus generates at least one optical tweezers on an examined object that carries at least one particle. The apparatus includes a laser source, a diffractive optical element and a convergent lens. The laser beam from the laser source passes through the diffractive optical element to produce a diffractive pattern. The laser beam is then received by the convergent lens and then to be focused on a plane of the examined object. The optic axis of the convergent lens is substantially not perpendicular to the plane of the examined object, so that the laser beam is projected onto the plane of the examined object in a skewed manner for providing a lateral momentum to move the particle.

An optical tweezers controlling device including a light source, an objective lens and a focus adjusting unit is provided. The focus adjusting unit disposed between the light source and the objective lens includes a mirror set and a zoom lens set. The mirror set has at least a mirror. The mirror is rotatable such that after a light of the light source is projected to the mirror, the reflective direction of the light reflected from the mirror is changeable. The zoom lens set has at least a zoom lens disposed in accordance with the mirror. By rotating the mirror or changing the focal length of the zoom lens, the focusing location of the light changes on the focal plane of the objective lens or in the front or the rear of the focal plane.

An optical tweezers lifting apparatus is provided. The optical tweezers lifting apparatus includes an optical tweezers and a particle-lifting device. The particle-lifting device includes a substrate and a plurality of electrodes that are disposed on the bottom of a flow path in the substrate. When a dielectrophoresis (DEP) solution with a plurality of floating particles is conducted into the flow path and upon those electrodes and a voltage is applied to these electrodes, these particles would be driven by a negative DEP force to move upward to a specific depth in the flow path. Meanwhile, the optical tweezers of the apparatus is selectively focused at the specific depth in the flow path.
