Abstract: The present invention can reduce interference generated by processors and other computing devices when a connected radio is active. In one embodiment, the invention may include determining a start of reception of radio signals by a radio, generating a radio active signal, transmitting the radio active signal to a coupled computer to affect the radio interference generated by the coupled computer. The embodiment may further include determining an end of reception of radio signals by the radio, generating a radio not active signal, and transmitting the radio not active signal to the coupled computer to affect the radio interference generated by the coupled computer.

Abstract: Systems and methods for moving a document cradle to facilitate imaging of a bound document are disclosed. The system may include a cradle supporting a document, such as a book, a cradle positioner for selectively positioning the cradle relative to a camera, and a controller for controlling the positioner to automatically position the cradle based on the location of the page being imaged relative to the camera. The cradle may be positioned such that a gutter of the book or a surface plane of each page being imaged remains in approximately the same position relative to the camera. The cradle positioner may include a servo motor controlling a shaft to position the cradle supported and guided by a bearing. A sensor (e.g., 3D camera, range finder, laser, and/or edge detector) may be provided to facilitate the controller in controlling the cradle positioner based on the location of the page being imaged relative to the camera.

Abstract: Systems and methods for pacing and error monitoring of a manual page turning operator of a system for capturing images of a bound document are disclosed. The system includes a speaker for playing music having a tempo and a controller for controlling the tempo based on an imaging rate and/or an error rate. The operator is influenced by the music tempo to capture images at a given rate. Alternative or in addition to audio, error detection may be implemented using OCR to determine page numbers to track page sequence and/or a sensor to detect errors such as object intrusion in the image frame and insufficient light. The operator may be alerted of an error with audio signals and signaled to turn back a certain number of pages to be recaptured. When music is played, the tempo can be adjusted in response to the error rate to reduce operator errors and increase overall throughput of the image capturing system. The tempo may be limited to a maximum tempo based on the maximum image capture rate.

Abstract: Systems and methods for acquiring and using three-dimensional imaging data to improve the process of scanning bound documents are disclosed. The system includes a camera for capturing an image of documents such as books, and a second camera for gathering data regarding the first camera's field of view. Signal processing logic analyzes the data gathered by the second camera and uses it to determine whether the imaging camera's view was obstructed. If it is determined that the imaging camera's view was obstructed, then remedial action can be taken, such as removing the obstruction, recapturing the image, and/or flagging the image for further processing. The second camera may include a laser range finder, a scanning laser range finder, an ultrasonic range finder, a device that utilizes auto-focus range finding technology, a binocular camera array, and/or a trinocular camera array.

Abstract: A user terminal can be authenticated by an access point based on one message. In one embodiment, the present invention includes the access point receiving a message containing a shared secret encrypted with an access point public key, a user terminal certificate, and an authenticator string demonstrating possession by the user terminal of a user terminal private key. The access point can decrypt the shared secret using the private key of the access point paired with its private key. The access point can then authenticate the user terminal by checking the authenticator string using a user terminal public key included in the user terminal certificate to verify possession of the user terminal private key by the user terminal.

Abstract: An emergency call recognition system which is activated when an off-hook situation occurs, which recognizes when an emergency number is dialed with or without the presence of a dial tone, and which provides the caller a communication channel to complete such a call. The present invention is used to give priority to emergency telephone calls. Typically the present invention is used in wireless local loop systems, however the present invention can also be incorporated into a conventional telephone system. The present invention uses an emergency call recognition system to determine if a person is dialing an emergency telephone number. If the emergency call recognition system recognizes a dialed telephone number as an emergency telephone number, then the caller is provided with a communication channel to complete the telephone call. The caller is provided a communication channel even if all of the communication channels are in use. This is accomplished by disconnecting calls that are not of an emergency nature.
