The present invention is directed to a reconfigurable finite impulse response filter that processes data tap values with canonical sign digit coefficients. The projector includes a device connection unit which enables communication between the information processing apparatus and the projector, a password generating unit which generates a password, and an encryption unit which encrypts the password and outputs the encrypted password to the information processing apparatus through the device connection unit. In some embodiments the method includes the steps of: inserting a catheter having a diameter no more than 21 french into the patient; endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve through the catheter; and deploying the anchor and the replacement valve. In the overlap zones, an exposure of the mask provides only a part of the patterns. The semiconductor pillar is buried in an interior of the through-hole. Embodiments generally include the use of viscosupplementation delivered intra-articularly in conjunction with rehabilitative therapy and an unloading knee brace.
