  • Publication number: 20060046180
    Abstract: A method of forming a xerographic image having at least one portion with a gloss different from a gloss of another portion of the xerographic image includes xerographically forming a toner image on a surface of a substrate and forming a finish over the toner image at the at least on portion, the finish being made of a differential gloss finish coating material that has a gloss different from that of the toner image. The differential gloss finish coating material is preferably an emulsion aggregation toner that is substantially free of pigments that adversely affect the transparency of the toner following fusing, the toner having gloss tunability through control of the amount of crosslinked portions included in the toner.

  • Publication number: 20060045239
    Abstract: An imaging system that removes an electrical charge from a sensor. The system includes a generator that generates s-rays, a sensor that stores an electrical charge, a plate positioned above the sensor and a light source. A controller determines whether the electrical charge should be removed from the sensor. If it is determined that the electrical charge should be removed, the controller controls the light source to illuminate the plate to distribute the light on a top surface of the sensor. A method includes arranging a plate above the sensor and a light source next to the plate, generating x-rays towards the sensor, and storing an electrical charge in the sensor. If it is determined that the electrical charge should be removed, the light source is controlled to illuminate the plate so that the light from the light source is distributed on a top surface of the sensor.

  • Patent number: 7006244
    Abstract: A xerographic marking device includes a source of pixels representative of digitized image information. A rendering image processor analyzes the pixels for an image characteristic, and based on the analysis assigns one of at least three values to each pixel. The three values are selected from a set of values representing positive, negative or neutral relative to a predetermined exposure bias. The device also includes an imaging output device which converts the values assigned to the pixels into areas of selective exposure on a charge retentive surface. A charge on the charge retentive surface such as a photoreceptor accordingly, includes an area of positive charge determined to electrostatically react with a charged monochrome marking agent or toner in a first manner, for example by attraction. The charge also includes a negative charge area which is determined to electrostatically react with the toner in an opposite manner, for example to repel toner.

  • Patent number: 7005222
    Abstract: An imaging member having a charge transport layer with multiple regions is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein at least the top or uppermost transport layer comprises a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be of the same or different compounds from that included in the top or additional charge transport layer(s). The charge transport compound present in each layer may be dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.

  • Patent number: 7006098
    Abstract: A method and apparatus for facilitating communication about a document between two users creates autonomous, animated computer characters, or avatars, which are then attached to the document under discussion. The avatar is created by one user, who need not be the author of the document, and is attached to the document to represent a point of view. The avatar represents the physical likeness of its creator. The avatar is animated, using an avatar scripting language, to perform specified behaviors including pointing, walking and changing facial expressions. The avatar includes audio files that are synchronized with movement of the avatar's mouth to provide an audio message.

  • Patent number: 7006999
    Abstract: A method for enabling privacy and trust in electronic communities is disclosed. A major impediment to using recommendation systems and collective knowledge for electronic commerce is the reluctance of individuals to reveal preferences in order to find groups of people that share them. An equally important barrier to fluid electronic commerce is the lack of agreed upon trusted third parties. We propose new non-third party mechanisms to overcome these barriers. Our solutions facilitate finding shared preferences, discovering communities with shared values, removing disincentives posed by liabilities, and negotiating on behalf of a group. We adapt known techniques from the cryptographic literature to enable these new capabilities.

  • Patent number: 7007091
    Abstract: A subject name of a personal certificate is used to easily perform access control. An authentication unit implements an authentication procedure between a client terminal and a web server. The authentication unit receives a certificate from the client terminal for executing the authentication procedure, and its subject name is supplied to an element extracting unit. The element extracting unit follows a hierarchy structure of the subject name to extract a predetermined element. A right determining unit determines an access right for accessing a document based on a type and a value of the element extracted, and allocates this to a session number. A right registering unit registers a relation between the session number and the access right. Thereafter, while the session continues, an access right is allowed based on the session number.
