FINGER GUIDE DEVICE
专利汇可以提供FINGER GUIDE DEVICE专利检索，专利查询，专利分析的服务。并且A finger guide device that positions a finger (or minutiae containing digit) of a human subject on a fingerprint sensor in a manner optimal for the data capture operation of authentication or identification of said subject wherein a relevant portion of the finger is in alignment with a sensor or scanner. Authentication or identification takes place by fingerprint matching. The finger guide device may also be used for enrollment of the initial fingerprint data into the system through one or more readings of the fingerprint and translation into a template for future comparison matching. The finger guide device may also serve to provide temperature or temperature equivalent tactile feedback or other forms of feedback to a user. The finger guide device may also contain an outer surface ridge which feels somewhat uncomfortable due to application of a high pressure per square inch on small areas of the finger when the finger is incorrectly positioned to encourage correct placement of the finger, which is more comfortable. The finger guide device may have a curved inside surface to contour to a wide variety of fingertip shapes and sizes, wherein the sides and front have shorter radii of curvature than the rearward portion of the finger guide device. The front of the finger guide device may have sufficient steepness of its sides and shortness of radius of curvature in order to serve as a stop positioning the tip of the finger approximately between .20 and .90 inch ahead of the center of the sensor. This is an ideal position to enroll and later to authenticate or identify a subject user. The finger guide device material or surface may be electrically conductive and thereby serve as a means to transmit a driver signal to the finger tissue to facilitate the improved use of capacitive or other types of electronic or electromagnetically operated fingerprint sensors requiring this electrical potential sensing means. Additional tactile enhancements such as twin positioning bumps or Braille or audio or mechanical motion or visual marking or indicator light feedback may be added within the finger guide device if desired. The level of the fingerprint sensor or scanner may be raised or lowered as an additional enhancement to alter the data capture characteristics. The finger guide device may be used in communication with electromechanical devices to serve the additional purpose of functioning as a switch or pointing device.，下面是FINGER GUIDE DEVICE专利的具体信息内容。
