Abstract: A multi-provider forms processing system with retry upon failure comprises: a plurality of portable computing devices, a plurality of service providers and a paper-like forms server coupled by a network. The paper-like forms server performs the scheduling, routing, logging, verification and billing for the paper-like processing of compound documents. The paper-like forms server comprises a central schedule, a retry module and a billing module. The multi-provider forms processing system is advantageous because it monitors for failure of transactions, automatically issues a retry or replacement transactions and adjusts the billing for the failed transaction. In particular, the central scheduler tracks and determines when transaction failures occur, and based on these failures revises the billing to users and credits to service providers.

Abstract: A system and a method for updating an electronic paper display are disclosed. A memory includes a waveform table and a transition matrix including multiple pixels, each representing a pixel of the electronic paper display. A page transition display system is coupled to the memory and identifies waveforms from the waveform table associated with multiple transition matrix pixels by processing multiple transition matrix pixels in parallel. For example, the page transition display system loads multiple transition matrix pixels into a register and accesses the waveform table using the contents of the register. Using the identified waveforms, the page transition display system generates control signals used to modify the electronic paper device.

Abstract: A method and apparatus is described for segmenting an image, for adaptively scaling an image, and for automatically scaling and cropping an image based on codestream headers data. In one embodiment, a file that can provide a header that contains multi-scale entropy distribution information on blocks of an image is received. For each block, the block is assigned to a scale from a set of scales that maximizes a cost function. The cost function is a product of a total likelihood and a prior. The total likelihood is a product of likelihoods of the blocks. The image is segmented by grouping together blocks that have been assigned equivalent scales. In one embodiment, the file represents an image in JPEG 2000 format.

Abstract: A handheld portable printer includes members and a handle that are joined together to form a generally O-shaped device. The members provide a rigid and strong structure and an area for housing a projector to project an image on the print surface of the image to be printed. The bottom member houses a pair of absolute position sensors spaced apart and aligned upon the longitudinal axis on the bottom of the handheld portable printer. A controller is associated with the absolute position sensors to produce precise position information. The controller uses the precise position information to control the projection of the image to be printed and the printing of pixels by the print head. In one embodiment, the print head is controlled such that each pixel is printed at least twice.

Abstract: A multi-provider forms processing system with a quality of service rating includes a plurality of portable computing devices, a plurality of service providers and a paper-like forms server coupled by a network. The paper-like forms server comprises a central scheduler and service provider manager and rater. The multi-provider forms processing system provides ratings for the service providers that are used in selection of services providers and processing of compound documents. In particular, the central scheduler tracks and determines where transaction failures occur, and based on these failures provides a quality of service rating for each service provider. The central scheduler also monitors the logs for completion as well as restarts, attempts, failure, reworked and re-performed transaction steps and provides ratings that can be reviewed by a user in selecting a service provider or automatically by a selection module.

Finally, the computer sends the metadata for storage in the global log of the paper-like document server, and the authorized document to the next step in the electronic workflow. The paper-like document server stores the metadata in other servers or entangles the global log with the logs of other servers for additional security.
