摘要： In accordance with the present invention, an acoustic ink printer comprises a pool of liquid ink having a free surface in intimate contact with the inner face of a perforated membrane. The printer addresses all pixel positions within its image field via substantially uniform, relatively large diameter apertures which extend through the membrane on centers that are aligned with respective ones of the pixel positions. In operation, one or more focused acoustic beams selectively eject individual droplets of ink from the ink menisci that extend across the apertures. Accordingly, the membrane is positioned and the bias pressure that is applied to the ink is selected so that the menisci essentially remain within the focal plane of such beam or beams.

摘要： An acousto-optic device which is incorporated into a fiber optic system to define, based upon device configuration, an element such as a phase modulator, optical tap, frequency shifter or mode coupler. The device comprises an acoustic transmission member having a groove therein which is secured in the Hertzian contact along a continuous portion of its surface with an optical waveguide so as to communicate acoustic signals from a transducer affixed on the member through the Hertzian contact area and into the optical waveguide. In one preferred embodiment the member comprises a capillary tube having a bore that is substantially the same diameter as the optical waveguide to which the device is to be affixed. A portion of the capillary tube is removed to expose the base, thereby defining a groove along the capillary substrate. In one preferred embodiment an acoustic transducer is deposited on the curved surface opposite the groove to focus acoustic signals from the transducer toward the groove. In another preferred embodiment, a portion of the capillary substrate opposite the groove is lapped to form a substantially flat surface which is parallel to the plane of the groove. An acoustic transducer is then deposited on the flat surface. The capillary substrate may also be lapped to form a wedge configuration for launching acoustic waves at an angle with respect to the groove. The optical waveguide is pressed into the groove to form the Hertzian contact with the groove.

摘要： The output surface of an acoustic printhead having one or more concave acoustic beam forming devices for supplying focused acoustic beams to eject droplets of ink on demand from the surface of a pool of ink is planarized by filling those concave devices with a solid material having an acoustic impedance and an acoustic velocity which are intermediate the acoustic impedance and the acoustic velocity, respectively, of the ink and of the printhead. This not only facilitates the cleaning of the printhead, but also eliminates the edges upon which an optional ink transport or the like may tend to drag. The outer surface of the filler may be essentially flush with the face of the printhead, or the filler may overcoat the printhead.

摘要： To facilitate the fabrication of acoustic printheads, arrays of spherical acoustic lenses are provided for bringing rf acoustic waves to essentially diffraction limited focii at or near the free surface of a pool of ink. These lenses produce focal patterns which are relatively free of localized amplitude variations, so they may be employed to fabricate acoustic printheads having relatively stable characteristics for acoustic printing.

摘要： Provision is made spatially stabilizing standing capillary surface waves in fixed and repeatable locations with respect to stationary external references. For spatially stabilizing such a wave on the free surface of a volume of liquid, the wave propagation characteristics of the free surface of liquid are periodically varied in a spatially stable manner at a spatial frequency equal to the spatial frequency of the standing wave or a subharmonic thereof, thereby locking the crests and troughs of the standing wave in predetermined spatial locations. A spatially periodic pattern of notches in a wall or base plate bounding the free surface of the liquid may be employed to physically modulate its wave propagation characteristics at a suitable spatial frequency. Alternatively freely propagating secondary capillary surface waves may be launched from spatially periodic sites along the free surface of the liquid to actively modulate its wave propagation characteristics at the diesired spatial frequency.

摘要： Medical diagnostic system, apparatus and methods are disclosed. Optical transmitters generate radiation-containing photons having a specific interaction with at least one target chromophore in a target structure, preferably a blood vessel such as the interior jugular vein. The optical transmitters transmit the radiation into at least a first area including a substantial portion of the target structure and into a second area not including a substantial portion of the target structure. Optical receivers detect a portion radiation scattered from at least the first area and the second area. A processor estimates oxygenation, pH or cardiac output based on the scattered radiation detected from the first area, and the scattered radiation from the second area.
