Abstract: A fingerprint sensor having a holographic phase grating glued on one right angle surface of a prism is described where a light source oriented normally relative to the hypotenuse surface of the prism illuminates an interface of the grating and finger surface. Incident light rays are refracted and absorbed where ridges of the finger surface contact the grating surface, whereas light rays are totally internally reflected in areas between and pores in finger surface ridges not in contact the grating surface. The reflected light rays, diffracted by the holographic phase grating, propagate normally (.perp.) back into the right angle prism where they are reflected normally (.perp.) out the remaining right angle surface of the prism by a second total internal reflection at the internal hypotenuse surface of the prism. The reflected light rays emerging from the sensor contain high contrast, detailed images of the ridges and valleys of the finger surface including pores in the ridges, i.e.

Abstract: A system for delivering a liquid phase precursor fluid into a process chamber as a vapor phase fluid at constant pressure, the system comprising: a vaporizer for vaporizing the liquid phase precursor fluid prior to injecting the vapor phase fluid precursor into the process chamber, and a controllable device for transporting a preselected volume of the liquid phase fluid precursor from a reservoir to the vaporizer responsive to the pressure at the outlet of the vaporizer prior to entering the process chamber where the transport device is operated as the pressure at the outlet of the vaporizer canister drops, whereby system pressure perturbances are minimized prior to entering the process chamber.

Abstract: A real time fingerprint verification system includes a recording device and a verification device each having a fingerprint scanner for generating a flat, dimensionally undistorted, high contrast, fingerprint image, and an intensity sensitive, spatial light modulator (SLM) for receiving and transforming the flat fingerprint image into a planar, coherent light image. In the recording device, the planar coherent light image beam of the fingerprint from the SLM is Fourier transformed, and input into a microscope objective lens system which expands the Fourier transformed beam image sufficiently to allow mechanical blocking of its central portion or order, whereupon it is directed to interact as an object beam with a reference beam from the particular coherent light source to record a holographic matched filter.

Abstract: A composite beam enclosure structure comprising one or more planar, rigid panel elements each having a platform with an upper surface, integral solid peripheral top and bottom and side edges, and one or more intersecting ribs standing on the bottom surface of the platform defining sectional configurations. Elongated, structural framing elements having integral opposing flanges spaced for receiving the side edges of one or more of the rigid panel elements are securely attached to the side edges of the rigid panel elements by attachment means such as screws, rivets, weld or other bond.

Abstract: A miniaturized fingerprint sensor has a holographic phase grating glued to a base surface of a trapezoidal prism which operates on light totally internally reflecting from a finger-coverslip interface protecting the exterior surface of the grating, diffracting the reflected light to propagate back through the base surface and out the top parallel surface of the prism in a converging beam having an optical axis normally oriented (.perp.) with respect to such parallel base and top surfaces of the prism. A mirror folds the emerging converging light beam directing it into a camera system. The converging light beam emerging from the top surface of the trapezoidal prism contains high contrast, detailed images of ridges, valleys and pores of a finger-surface interface oriented in a plane normal to the optical axis.

Abstract: A golf course distance marker suited for anchoring in grassy turf includes a cap, an integral hole stop shoulder, a circumferential blade depending from the outside periphery of the shoulder, and a central anchor stem. Distance data is indicated preferably on one or more, removable, colored coded tabs or colored strips sandwiched between the marker cap and a transparent, removable tabs which snap into and anchor within a pair of slots through the top surface of the cap. The circumferential blade extends downward around the periphery of the marker, so that rotation of the marker rotates the blade to cut into the grassy turf at the location being marked. The anchor stem extends coaxially downward below the circumferential blade to insure axial rotation of the marker as the blade cuts into the turf.

Abstract: A method for defining and writing parallel and concentric magnetic signal tracks to a spinning disk surface of a magnetic data storage disk drive system using the components of the Head Disk Assembly (HDA) implemented by an appropriately programmed digital signal central processing unit (CPU) or micro code in an integrated circuit (IC) and a digital signal random access memory RAM is described wherein an initial magnetic signal track is written under least (minimum) energy equilibrium conditions with undulating boundaries and a meandering center line relative to axes of the spinning disk surface for one revolution of the surface. Then servoing to an edge of the just written track, a digitized position signal table is created in memory for storing digital position signals representing the amplitude of the signals read from n sampling points per disk revolution over a number of disk revolutions, where n is determined with reference to `Nyquist criteria`.

Abstract: A system for loading toner into a large capacity printer and copier machines includes a base adapter with a swiveling filler snout for receiving and latching onto a spout of a large toner container. The axis of filler snout is oriented at angle .PHI. with respect to its swivel axis which in turn is tilted at angle .PHI. with respect to the vertical. Accordingly, the filler swivels between a retracted stow position where the filler snout extends vertically over the base adapter and an extended position where the snout tilts at angle 2.PHI. from the vertical for receiving and latching onto the spout of the toner container. The spout of the toner container and the mouth of the filler snout have mating surfaces facilitating latching of the container spout within the snout.
