摘要:
A power-up switch circuit in a peripheral device such as a keyboard is coupled to the main processing portion of a computer via an interface bus. The switch circuit together with bias and detection circuitry in the main processing portion allow non-intrusive use of a data communication line of the interface for controlling the supply of power to the main processing portion, without requiring a dedicated power-on wire between the peripheral device and the processing portion. A repeater circuit between the keyboard and the main processing portion causes a second signal to be sent through an upstream portion of the interface bus in response to receiving a first signal through a downstream portion of the bus, while the main processing portion is in low power mode. The repeater is also configured to not affect the interface bus when the main processing portion is in high power mode.

Power usage of a portable computing device is modified to more efficiently use a power supply included in the portable computing device. Power usage by different components of the portable computing device is modified based on use of the portable computing device to allow dynamic modification of power consumption. The portable computing device includes data describing various power management states and the portable computing device transitions between different power management states as it is used, modifying the power consumption of various components in different power management states. Various communication device operating states are also defined to modify power usage by communication devices included in the portable computing device based on device usage.

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. The present invention also includes a number of novel methods including: a method for printing an image with a handheld printer, a method for projecting an image to be printed, and a method for registering a location of a printer and portions of a printed image.

A system for paper-like forms processing includes a plurality of portable computing devices coupled by a network to a paper-like forms server. The portable computing devices are adapted to receive images (e.g., compound documents/forms), add stroke annotations to the received images, and send the annotated received images or the stoke annotations themselves to the paper-like forms server. The paper-like forms server comprises a central scheduler and a logging module. The paper-like forms server processes compound documents as paper like forms and sends input to and receives results from service providers to perform various types of paper like processing on the compound document. The paper-like forms server performs the scheduling, routing, logging, verification and billing for the paper-like processing of compound documents. The central scheduler also stores results from service providers for later retrieval.

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.

A system for using accelerometer-based detection of physical movement for document sharing provides easy and intuitive ways to securely share documents, even without passwords, between computing devices. The system of the present invention includes: at least two computing devices that each have a motion detection device capable of detecting sudden movements and generating a unique signature. The unique signature can then be used to generate signatures or shared secrets for controlling the transfer of data between devices. The motion detection device is capable of detecting sudden movement such as the tapping of the two computing devices together, tapping a stack of computing devices, tossing a computing device in the air. The system may optionally include an intermediary device such as a server for transferring the documents or files between computing devices such that only a small decryption key and file pointer is needed to share records between computing devices. The present invention also includes a novel method for accelerometer-based detection of movement for transferring data between computing devices.

A system and method for applying a pre-existing physical seal authorization to documents provides for authentication of electronic documents using physical seals and without interrupting the electronic workflow. The system of the present invention includes a seal capture device coupled to a computer, and the computer coupled by a network to a paper-like document server. The seal capture device detects depression of a seal thereon and outputs the image of the seal and other metadata to the computer. The computer stores the metadata in its local log using a logging module. The computer also adds the image of the seal and other metadata to the electronic document being displayed. 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.
摘要:
The present invention overcomes the deficiencies of the prior art with a system for stroke and image aggregation and analytics. The system is particularly advantageous because it provides a system for distributing page images such as worksheets, examinations or forms to multiple devices. The system allows independent paging and writing on the distributed materials; collection of the strokes added to the distributed pages images; and aggregating and displaying those strokes or summary information in a useful manner. For example, an instructor might receive the current work of the students for a particular examination question and view those strokes in a parallel manner or a combined manner.

The portable computing device includes a display, a plurality of sensors for detecting light, a light detection module and a page changing module. The sensors are positioned to detect light from the MFP and trigger a page change automatically. The MFP in accordance with the present invention includes a scanner with a platen, a page change detection module, an image processing module, a device identification module, and a document matching & retrieval module. The page change detection module is adapted to receive the images presented by the portable computing device on the platen of the scanner for copying. The page change detection module detects changes and causes the MFP to scan and output a copy.
