摘要： The present invention describes a method for superimposing prespecified locational, environmental, and contextual controls on user interactions, including interactions of mobile users, with computational resources. A system is described for electronically monitoring contextual information concerning users and machines, including state and locational information including proximity. Interaction policies, including user specified interaction policies, may be registered on an identifiable address path. Methods are described for detecting, selecting and controlling computercontrolled devices, based on the proximity of the device to the user, the current context of the user, the location of other nearby users and devices, and the current state of the devices. Temporary transfer of control, including exclusive control, of particular computers and computer controlled devices to individual users based on the context and environment in proximity to those computing devices is also described.

摘要： In a large area display system, multiple persons may work together with multiple input devices for supplying and receiving information in an interactive system with a single large area display. The large area display system comprises a screen wherein computer generated information is projected upon one side of the screen, and users interact with the computer from the opposite side of the the screen. Data coordinates for an input device corresponding to a pseudo image sensed by the receiving subsystem electronics are provided to the controlling computer. The input data coordinates from the pseudo image are normalized for variations due to frequency dependence and electronic drift. The normalized data coordinates are looked up in a calibration table to account for distortion in the pseudo image detection electronics. Screen coordinates corresponding to pixel locations on the large area screen are found by interpolation from the data From the calibration table. The calibration table is prepared off-line, based on a bicubic spline interpolating function which is then compressed using a delta compression scheme. During on-line operation of the system, screen coordinates are looked-up directly from the compressed table. The screen coordinates are then jitter smoothed to provide a smooth path of response closely conforming to original input locations. The jitter smoothing method uses an exponential function based on the magnitude of the change in the position of the input.

摘要： The free ink surface levels of acoustic ink printers are controlled by cap structures that have substantially non-retroreflective aperture configurations. The non-retroreflective configurations of the apertures of these cap structures cause diffusive scattering or directional deflection of the reflected surface ripple waves, thereby significantly reducing the time that is required for the oscillatory perturbations, which are caused by reflection of the surface ripple waves that are generated during the droplet ejection process, to dissipate to a negligibly low amplitude in the critical local areas of the ejection sites. This, in turn, increases the droplet ejection rates at which printers having such cap structures can be operated asynchronously.

摘要： This disclosure relates to semiconductor varactors, such as thin film poly-Si varactors, which have larger effective gate areas in accumulation than in depletion, together with capacitive switching ratios which are essentially determined by the ratio of their effective gate area in accumulation to their effective gate area in depletion. To that end, such a varactor has a fully depletable active semiconductor layer, such as a thin poly-Si film, and is constructed so that at least a part of its active layer is sandwiched between a relatively thin dielectric layer and a relatively thick dielectric layer. The thin dielectric layer, in turn, is sandwiched between the active semiconductor layer and a gate electrode. Furthermore, one or more ground electrodes are electrically coupled to laterally offset portions of the active semiconductor layer in partial overlapping alignment with the gate electrode. In keeping with this invention, the capacitance per unit surface area of the thin dielectric layer is so much greater than the capacitance per unit surface area of the thick dielectric layer that the series capacitance of the depleted active semiconductor layer and the thick dielectric layer negligibly contribute to the capacitance of the varactor when it is operating in its depletion mode. Top-gate and bottom-gate embodiments having ground electrodes which are coplanar with the active semiconductor layer, ground electrodes which are in a plane adjacent to the active semiconductor layer, segmented gate electrodes and segmented ground electrodes, and continuous gate electrodes and segmented ground electrodes are disclosed.

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 acoustic ink printhead having improved ink drop ejection control includes a substrate having an array of acoustic lenses at its upper surface for bringing rf acoustic waves to a predetermined focus and a layer of acoustically reflective material of a thickness equal to an odd multiple of one quarter of the wavelength of the acoustic rf waves passing through it having openings corresponding to and positioned above each lens. Ink from an ink pool is allowed to couple acoustically to the lenses at each opening for receiving the focussed acoustic rf wave, while the layer acoustically isolates the interstitial regions between each lens by reflecting the acoustic rf waves incident on the upper surface of the substrate in those regions.

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.
