Abstract: The present invention provides an apparatus and method for high-speed ultrasonic data acquisition. The apparatus is arranged within an ultrasonic detection system, and comprises: an acquisition interface, coupled to the ultrasonic detection system, for obtaining ultrasonic data from the ultrasonic detection system; a large-capacity buffer for holding the ultrasonic data obtained by the acquisition interface; a high-speed USB (Universal Serial Bus) controller, for transferring the ultrasonic data in the large-capacity buffer to the host computer via a USB interface.

Abstract: Disclosed is a door latch assembly having an integrated means to accommodate multiple backset dimension requirements while facilitating the backset adjustment selection to be done in an easy and convenient manner. The multiple backset latch has as primary components a housing body assembly and a latch bolt housing assembly. The latch bolt housing assembly includes a housing body channel member, a cam support plate member, a bolt retractor member, a cam lever member, a positioning spring member, and a housing body plate. The latch bolt housing assembly further includes a latch bolt head. The housing body channel has an oval aperture corresponding to accept the cam lever member. The oval aperture has multiple radii sufficient to accommodate lateral movement to provide 60 mm (2? inches) and 70 mm (2¾ inches) backset.
