摘要： A technique for fingerprint classification and/or identification, in which a fingerprint is defined by areas containing patterns of ridges and valleys. At least one local pattern is determined using locations and characterizations of the fingerprint, which are indicated by a rapid change in direction of the ridges and valleys. The fingerprint is classified into types based upon the relative locations and characterizations of said local pattern(s). The fingerprint identification process can utilize minutiae location and angles as well as local pattern characterizations. Neural networks are utilized in determining the local patterns. The amount of data required to store data defining the fingerprints using the local pattern and/or minutiae techniques is significantly reduced.

摘要： An interacting exercise device is revealed. The interacting exercise device includes a driving device and a non-concentric actuator driven by the driving device. While the driving device is operated to rotate, the non-concentric actuator vibrates and the vibration generated is delivered to the interacting exercise device for interacting shaking fitness.

摘要： A method of making a buffer board of a treadmill includes a sizing step, a shade drying step, a presetting step, a clamping and heat-pressing step, a cooling step, and a die opening step. The method can easily make the desired buffer board adapted to the treadmill and can only change different dies to make buffer boards with different structures when an upper die and a lower die of a die set provide protrusions, flat surfaces or depressed surfaces, thereby reducing the manufacturing cost.

摘要： A pedal-type vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. The user can fully exercise the muscles of the body during exercise, and the vibrational effect generated by the eccentric assembly can stimulate the acupuncture points of the body to improve the blood circulation. The left and right pedals can be treaded in turn to continuously drive a gear to rotate in the same direction so as to achieve the effect of acceleration and to enhance vibrations.

摘要： A method for manufacturing a massage wear-resistant treadmill deck and a finished product thereof are provided. The method includes step 1: providing a mold, the mold having a plurality of cavities thereon, a wear-resistant material being injected into the cavities of the mold; step 2: placing a deck in the mold so that the wear-resistant material is bonded to a surface of the deck to form a plurality of massage protrusions on the deck; and step 3: demoulding the deck from the mold, the surface of the deck being formed with the massage protrusions to form the massage wear-resistant treadmill deck. A wear-resistant layer having the massage protrusions is first formed in the mold, and then the deck is placed into the mold to bond with the wear-resistant layer to form the massage wear-resistant treadmill deck. The manufacturing cost is reduced and the manufacturing mobility is improved.
