摘要： A detector array method and apparatus for real time in-situ color control in printers and copiers includes an array for performing a linear matrix transformation on color patch information generated by a printer or copier. A light sensor array detects color components from a series of color test patches and performs a predetermined matrix transformation on the color information to produce a set of control signals for feedback to the printer or copier. In another embodiment, the light sensor array is extended to produce a fully analog neural network processor which is capable of arbitrary mappings of the color information into control signals for use by the printer or copier apparatus. The system is fully programmable, adaptive and, in one embodiment, trainable using backpropagation or other techniques.

摘要： A user interface is implemented using visual indicia and a background for the visual indicia that encodes address information. The background appears visually as a stipple pattern, but is implemented using glyphs which form an address carpet that encodes address information uniquely identifying each location of the user interface. An image capture device is used to capture an area of the address carpet that is at or near visual indicia of interest to the user while selecting a location in the visual indicia. The image capture device captures the area of interest, and transmits the image area to a computer for processing. The computer first determines the proper orientation of the image, and then decodes the information encoded by the glyphs. The decoding results in an X, Y address identifying the location of the captured area in the address carpet and, by reference, the address of the selected location. Based on the address, the computer may perform an operation associated with the area.

摘要： Bands of predetectors (92) detect the approach of lines of glyphs (12, 14) within an image being scanned. Linear lines or arrays of glyph detectors (116, 118, 120) are sampled in accordance with the detected approach of lines of glyphs. Each detector array includes a plurality of analog glyph detectors (20, 50) which respond to the presence of glyphs with a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a second polarity or characteristic in response to glyphs of a second orientation. The analog signals which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog detectors and the information encoded in the glyphs is directly output as a binary signal without computer analysis of the image.

摘要： A method and apparatus for transporting electrically charged particles suspended in a fluid, such as ions or the like, through said fluid, in a transport direction by means of a traveling electrostatic surface wave. The apparatus includes an array of transport electrodes to which a source of AC multi-phase potential is applied to create a stable and controllable particle transport system in which the charged particles have a compound motion comprising a generally cyclical movement and drift movement through the fluid, in the transport direction. The locus of charged particle movement is maintained above the surface of the electrode array.

摘要： A system for fluid transport is provided where a quantity of fluid is held in a reservoir. A droplet generator is employed to generate droplets from the fluid, for example a nozzle-based system or a nozzleless system such as an acoustic ejection system. A generated droplet has a trajectory whereby it arrives at a target. A circuit is used to modify one or more characteristics of the generated droplet in a way which increases the likelihood that the droplet will not splash or bounce when it arrives at the target. The circuit may in different embodiments control the speed of the droplet or the Weber number of the droplet. The circuit may create an electric field in an area of space where the droplet passes. The circuit may charge the droplet by causing it to contact ions.
