Abstract: An ultrasonic positioning device for a five-axis machine includes an ultrasonic device and a positioning plate. The ultrasonic device is adapted to fix a material and generates ultrasonic vibrations to the material. The positioning plate is adapted to fix the ultrasonic device and pivotally connected the five-axis machine for the material to be controlled by the five-axis movement on the five-axis machine. By cooperating with the ultrasonic vibrations, a processing portion of the five-axis machine can process the material.

Abstract: An ultrasonic tooth making machine comprises: a tooth making machine, a work table, and a vibration device. The tooth making machine has a machine tool to perform machining operation. The work table is mounted on the tooth making machine to hold a rough blank tooth, and the work table and the machine tool are able to move with respect to each other. The vibration device is located between the work table and the rough blank tooth to put the rough blank tooth in an ultrasonic vibration environment. When the machine tool is controlled to move with respect to the work tale while the vibration device is powered on, the rough blank tooth, in the ultrasonic vibration environment, is capable of being machined into at least one artificial tooth at one time.

Abstract: A machine tool with an ultrasonic device includes a machine tool unit, a fastening unit, and an ultrasonic unit. The machine tool unit includes a working device and a worktable. The working device has a working member to process a workpiece. The fastening unit is disposed on the worktable to mount and fasten the workpiece. The ultrasonic unit is located between the worktable and the fastening unit. When the working member and the ultrasonic unit are activated, the workpiece is processed by the working member, and the ultrasonic unit generates ultrasonic vibrations to the fastening unit and the workpiece placed on the fastening unit to clear filings from the workpiece during operation to enhance the work efficiency greatly.

Abstract: A fingerprint identification assembly includes a laminated lens having a first lens, a second lens and a third lens formed together with the first lens and the second lens, each of the first lens, the second lens and the third lens has a dielectric film coated thereon. At least one illuminator is located at a bottom of the laminated lens and a sensor located under the laminated lens for picking up an image of a fingerprint on top of the laminated lens. The dielectric film of the laminated lens allows light from the at least one illuminator to be partially reflected due to the fingerprint on the laminated lens and partially penetrates through the second lens and the third lens to be picked up by the sensor.

Abstract: A fingerprint identification assembly includes a body having an objective lens mounted on top of the body for receiving thereon a fingertip and a first reflective lens mounted on a bottom of the body to receive reflected light from the objective lens, a light source emitting light to the first reflective lens and a sensing device integrally formed with the body and having a second reflective lens to receive the reflected light from the first reflective lens and a sensor to receive the reflected light from the second reflective lens so as to compare the received reflected light with information stored inside the sensor.

Abstract: The present invention provides a kind of compact-thin contact image sensor, particularly a fingerprint optical input apparatus, which can extract fingerprint image with a strip-type sensor. And it can produce fingerprint image with high definition, and shorten its size with the multibend light pipe. In addition, it has an enough guiding length for forming a strip area distributed uniformly, and the light would project on the strip-type fingerprint pressed on a transparent panel from some angle and reflect to the strip-type sensors by total internal reflection. Lastly, the forest fingerprint image would be extracted by moving the finger.
