Definitions

• Figure 2 is a schematic view of a interaction between a netpage pen, a netpage pnnter, a netpage page server, and a netpage application server,
• Figure 3 illustrates a collection of netpage servers and pnnters interconnected via a network
• Figure 4 is a schematic view of a high-level structure of a pnnted netpage and its onlme page desc ⁇ ption
• Figure 5 is a plan view showing a structure of a netpage tag
• Figure 33 is a schematic view of a digital ink class diagram
• the netpage pen 101 mteracts with the coded data on a pnnted netpage 1 and communicates, via a short-range radio link 9, the mteraction to a netpage pnnter
• the pnnter 601 sends the mteraction to the relevant netpage page server 10 for interpretation
• the page server sends a co ⁇ esponding message to application computer software nmnmg on a netpage application server 13
• the application server may in turn send a response which is pnnted on the ongmating pnnter
• the netpage pnnter exploits the growing availability of broadband Internet access Cable service is available to 95% of households m the United States, and cable modem service offering broadband Internet access is already available to 20% of these
• the netpage pnnter can also operate with slow er connections but with longer delivery times and lower image quality Indeed, the netpage system can be enabled usmg existing consumer inkjet and laser pnnters, although the system will operate more slowly and will therefore be less acceptable from a consumer's pomt of view
• the netpage system is hosted on a pnvate intranet
• the netpage system is hosted on a smgle computer or computer-enabled device, such as a pnnter
• the sensmg device In order to support "single-click" mteraction with a tagged region via a sensmg device, the sensmg device must be able to see at least one entire tag m its field of view no matter where m the region or at what onentation it is positioned The required diameter of the field of view of the sensmg device is therefore a function of the size and spacmg of the tags
• the tag image processmg and decodmg performed by a sensing device such as the netpage pen is shown in Figure 7 While a captured image is bemg acquired from the image sensor, the dynamic range of the image is determined (at 20) The center of the range is then chosen as the binary threshold for the image 21 The image is then thresholded and segmented mto connected pixel regions (l e shapes 23) (at 22) Shapes which are too small to represent tag target structures are discarded The size and centroid of each shape is also computed
• the presence of the most abstract document descnption on the page server allows a user to request a copy of a document without bemg forced to accept the source document's specific format The user mav be requesting a copy through a pnnter with a different page size, lor example Conversely, the presence of the formatted document descnption on the page server allows the page server to efficiently interpret user actions on a particular pnnted page
• a formatted document 834 consists of a set of formatted page descnptions 5, each of which consists of a set of formatted terminal elements 835 Each formatted element has a spatial extent or zone 58 on the page This defines the active area of mput elements such as hyperlinks and input fields
• a document instance 831 corresponds to a formatted document 834 It consists ol a set of page instances
• a page instance consists of a set of terminal element instances 832 An element instance only exists if it records instance-specific information Thus, a hyperlink instance exists for a hyperlink element because it records a transaction ID 55 which is specific to the page instance, and a field instance exists lor a field element because it records mput specific to the page instance An element instance does not exist, however, for static elements such as textflows - 12 -
• Pnnters not enabled for IR pnntmg have the option to pnnt tags usmg IR-absorptive black ink. although this restncts tags to otherwise empty areas of the page Although such pages have more limited functionality than IR-pnnted pages, they are still classed as netpages
• MemjetTM is a drop-on-demand inkjet technology that mcorporates pagewidth prmtheads fabncated usmg microelectromechamcal systems (MEMS) technology
• Figure 17 shows a single pnntmg element 300 of a MemjetTM pnnthead
• the netpage wallpnnter mcorporates 168960 printing elements 300 to form a 1600 dpi pagewidth duplex pnnter
• This pnnter simultaneously prints cyan, magenta, yellow, black, and mfrared inks as well as paper conditioner and ink fixative
• Figure 18 shows a small part of an a ⁇ ay of pnntmg elements 300, mcludmg a cross section 315 of a p ⁇ nting element 300
• the cross section 315 is shown without ink, to clearly show the ink mlet 312 that passes through the silicon wafer 301
• the active sensmg device of the netpage system is typicallv a pen 101 , which, usmg its embedded controller
• the help menu provides a hierarchical manual on how to use the netpage system
• the subscnber builds a dailv newspaper bv selecting one or more contnbuting news publications, and - 22 - creating a personalized version of each
• the resulting daily editions are pnnted and bound together mto a smgle newspaper
• the vanous members of a household typically express their different mterests and tastes by selecting different daily publications and then customizing them
• the reader may optionally enable collaborative filtenng This is then applied to articles which have a sufficiently long lifetime
• Each article which qualifies lor collaborative filtenng is pnnted with rating buttons at the end of the article
• the buttons can provide an easy choice (e g "liked ' and "disliked'), making it more likely that readers will bother to rate the article
• the reader specifies how quantities, dates, times and monetary values are localized This mvolves specifying whether units are impenal or metnc, a local timezone and time format, and a local currency, and whether the localization consist of in situ translation or annotation These preferences are denved from the reader s locality by default
• the netpage publication server computes the approximate multi-dimensional size of a publication's saleable advertising space on a per-section basis, taking mto account the publication's geographic coverage, the section's readership, the size of each reader's section edition, each reader's advertising proportion, and each reader's demographic
• the netpage system allows the advertising space to be defined m greater detail, and allows smaller pieces of it to be sold separately It therefore allows it to be sold at closer to its true value
• the netpage registration server acts as a proxy for the netpage user (l e the cardholder) m SET payment transactions
• the first step to bemg able to make SET payments is to register the user s biometnc w th the netpage registration server This is done in a controlled envuonment, for example a bank where the biometnc can be captured at the same time as the user's identity is venfied
• the biomet ⁇ c is captured and stored m the registration database linked to the user s record
• the user's photograph is also optionally captured and linked to the record
• the SET cardholder registration process is completed, and the resulting pnvate signature key and certificate are stored m the database
• the user's payment card information is also stored, givmg the netpage registration server enough information to act as the user's proxy m any SET payment transaction
• the system also maintains an mdependent certificate and p ⁇ vate signature key for each of a user's applications, to allow it to sign application transactions on behalf of the user usmg only application-specific mformation
• a resource descnption may identify nghts holders 920
• the netpage system automatically transfers copynght fees from users to nghts holders when users p ⁇ nt copynght content
• a communications protocol defines an ordered exchange of messages bet een entities
• entities such as pens, pnnters and servers utilise a set of defined protocols to cooperatively handle user mteraction with the netpage system
• Each protocol is illustrated by way of a sequence diagram in which the honzontal dimension is used to represent message flow and the vertical dimension is used to represent tune
• Each entity is represented by a rectangle containing the name of the entity and a vertical column representing the lifeline of the entitv Dunng the time an entity exists, the lifeline is shown as a dashed lme Dunng the tune an entity is active, the lifeline is shown as a double lme Because the protocols considered here do not create or destroy entities, lifelines are generally cut short as soon as an entity ceases to participate m a protocol
• the application (I e publisher) first obtains a document ID 51 for each document from an ID server 12 It then sends each document structure, mcludmg its document ID and page descnptions, to the page server 10 responsible for the document's newly allocated ID It mcludes its own application ID 64, the subscnber's alias ID 65. and the relevant set of multicast channel names It signs the message usmg its pnvate signature key
• the digital signature includes the alias D 65 of the correspondmg user This allows a smgle form to capture multiple users' signatures 5.5 FORM SUBMISSION PROTOCOL
• Screw threads 113 surrounding an aperture 113A on the cover 107 are a ⁇ anged to receive a metal end piece 114 mcludmg correspondmg screw threads 115
