  • Publication number: 20060143677
    Abstract: Methods, and apparatus for carrying out the methods, are disclosed for synchronizing a plurality of RF transmitters that are supplied with a common digital information signal for carrier modulation and subsequent transmission on a common channel throughout a prescribed region, whereby the digital signal receivers within the region may receive transmissions on the channel from more than one transmitter. The method involves inserting reference signals into the data sent to the transmitters in order to place them into known states at specific times relative to the digital signals sent to them for transmission. As a result of this method, the digital signals transmitted by each of the transmitters will be identical to one another so that the receivers will be able to identify one received signal as the main signal and the others as echoes.

  • Patent number: 7023472
    Abstract: An imaging device is calibrated using a flat, featureless surface and uniform illumination, relying on the effect of off-axis illumination and vignetting on the reduction of light into the camera at off-axis angles. The effect of the tilt of the camera is also considered. These effects are used to extract intrinsic camera parameters including focal length, principal point, aspect ratio and skew.

  • Patent number: 6946225
    Abstract: A multi-active electrophotographic charge generation element comprises a conductive support, a charge generation layer (CGL) disposed on the conductive support, and a charge transport layer (CTL) disposed on the charge generation layer. The charge generation layer (CGL) includes a charge-generation material comprising an aggregated or crystalline form of a first dye or pigment and a first polymeric binder. The charge transport layer (CTL) comprises at least one charge-transport agent, a second dye or pigment having absorption in a selected spectral region that at least partially overlaps the absorption of a dissolved non-aggregated or non-crystalline form of the first dye or pigment, and a second polymeric binder. The second dye or pigment in the charge transport layer absorbs radiation in the selected spectral region that is incident on the charge transport layer, thereby shielding the charge generation layer from that radiation and mitigating visible radiation-induced photofatigue.

  • Patent number: 6866977
    Abstract: Disclosed are photoconductive elements including a conductive support, e.g., an electrically conductive film, drum, or belt, on which a negatively chargeable photoconductive layer is disposed. An electrical barrier layer is disposed between the conductive support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges, but transports electrons under an applied electric field. In embodiments, the barrier layer can transport charge by electronic mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyamide-co-imide having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula: wherein Ar1 and Ar2 respectively represent tetravalent or trivalent aromatic groups of 6 to about 20 carbon atoms, and X is O, C(CF3)2, S?O or SO2.

    Abstract: Disclosed are polymers which include tertiary aryl amine moieties that can function as hole transport agents and which also have reactive silane groups thereon capable of being condensed to a silsesquioxane composition, as well as the silsesquioxane compositions prepared therefrom. The silsesquioxanes can be coated onto substrates to form abrasion-resistant layers having hole transport properties useful in devices that require charge transport properties, such as light-emitting diodes and organic electrophotographic elements such as photoreceptors or photoconductors. Also disclosed are electrophotographic elements which comprise an electrically conducting layer, a charge generating layer overlying the electrically conducting layer, and a charge transport layer overlying the electrically conducting layer. The charge transport layer, which can be an overcoat overlying the charge generating layer, comprises the condensed reaction product of the disclosed polymers.

  • Patent number: 6666596
    Abstract: Apparatus is disclosed for re-applying dye to a dye donor element of a dye transfer thermal printer. A reservoir contains a supply of dye that is thermally transferred from the reservoir to the dye donor element by diffusion of dye into the dye donor element. The reservoir has a diffusion controlled permeation membrane through which dye is delivered to the dye donor element, while inhibiting diffusion of a binder, whereby the dye diffuses between the reservoir and the dye donor element but the binder does not.
