Abstract: In one aspect of a computer-implemented method of diagnosing formatting errors in document renderings, first and second renderings of a document are generated that correspond respectively to first and second locales. A first difference in a display characteristic of a first textual element of the document in the second rendering as compared to the first rendering is identified based on a first predefined criterion. A report is generated specifying the first textual element as having the first difference. In another aspect of the method, a rendering of a document is generated that corresponds to a locale. It is determined that a first element of the document having a first element type has a format in the rendering distinct from a format associated with the first element type in the locale. A report is generated specifying that the first element has a potential formatting error.

Abstract: Apparatus and systems, as well as methods and articles, may operate to identify and locate an RFID-tagged object relative to a point on a body, including a human, animal, or robotic body.

Abstract: A system for identification and tracking of a tag distributed in a room is presented. A laser base station is configured to scan laser beams through a portion of a room. A tag is configured to be reactive to incident laser beams scanned from the laser base station to provide a data signal back to the laser base station. A tag tracking system is configured to receive input derived from the data signal from the laser base station. The tag tracking system stores state records of position and informational content of the tag generated from the input. The tag tracking system determines angular position of the tag with respect to the laser base station based on the position and information content of the tag stored in the state records.

Abstract: Various embodiments or the invention may use changes in the quantity of responses received from an RFID-tagged object to derive parameters that indicate probably movement or the object. In some embodiments, multiple RFID tags and/or multiple RFID readers may be used in conjunction with one another to further refine the probability of movement and/or to indicate the probability of a particular type of movement.

Abstract: A system for N-space navigation of digital data sets. The system includes an electronic tag having a digitally readable identifier, an electronic tag reader configured to read the identifier of the electronic tag, and a computing system connected to the electronic tag reader to provide digital navigation services of N-space data sets in response to reading the identifier of the electronic tag. The computing system generates at least one transitional data point in N-space for output between a currently displayed start point and a target point referenced by the identifier.

Abstract: Systems and methods for facilitating electronic transactions via a device capable of communicating with a network. The method includes providing a catalog on the network and communicating with the network via the device. The catalog is downloaded to the device and communication is discontinued with the network via the device. At least one desired transaction within the catalog is selected and stored on the device. The device recommunicates with the network and the at least one desired transaction is completed.
