Abstract: 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.

Abstract: A roof construction system wherein loosely-laid membranes on the top of a roof are held in place on the roof by suction forces when the wind blows, the suction forces varying directly in proportion to the wind velocity which would otherwise tend to lift the membrane so that frontal pressure and drag could dislodge or damage the roofing.
