A method and system for localizing an object among a set of objects, each equipped with an improved RFID tag. The tag includes an RFID chip, an antenna, a visual indicator, an AC/DC converter, and at least a pair of conductive surfaces adapted for receiving power from an external source and for powering the electronic chip according to capacitive coupling. Each conductive surface of the pair is designed to form the half of a capacitor, the capacitor being formed when the electronic tag and a similar electronic tag are attached to a neighboring adjacent object. To localize an object, an RFID reader is used, fed with the identifier of the object to be localized. All the capacitively coupled RFID, in the RFID reader range, receive a reading trigger that carries the identifier. The RFID tag compares the received identifier with its own identifier and if they match, then the capacitively coupled RFID reacts by providing a visual indicator; otherwise, if they do not match, the capacitively coupled RFID does not react.

The present application provides an method and system for verifying a user's identity within a virtual world environment. The verification is to be in real-time and avoids the possibility of providing credential (e.g., biometric information) that were previously authentication, by sending to the user a time-sensitive challenge and requiring the user to provide the requested credentials (e.g., biometric information) within a predetermined time period. Therefore, the present invention is best positioned for environments where trusted identification of a user is needed online to facilitate secure transactions.

The present invention is directed to a method and apparatus for reading short distance emission RFID tags to locate items in a container. A method in accordance with an embodiment of the present invention includes: initiating a reading sequence of a plurality of first RFID tags, wherein each first RFID tag is associated with a respective item located in the container, and wherein each first RFID tag emits an identification (ID); capturing the ID emitted by each first RFID tag using a plurality of second RFID tags located in a vicinity of the first RFID tag; interrogating the plurality of second RFID tags to obtain the captured IDs; and determining a physical location of an item in the container based on the captured IDs.

The present invention provides for the recovery of characters entered into at least one data entry zone of a data entry window. A method in accordance with an embodiment includes: storing a first image of the data entry window during data entry; subtracting a reference image from the first image to obtain a delta image, wherein the reference image is an image of the data entry window without data entered; identifying at least one non empty zone of the delta image and the location of the at least one data entry zone on the data entry window from the location of the at least one non empty zone on the delta image; extracting at least one character by applying optical character recognition to the least one non empty zone; and inputting the at least one character into the location of the at least one data entry zone.
摘要:
The first data flow is buffered at a receiver, and the buffer contents are scanned for metadata. Where metadata are found indicating a second data flow which has not yet arrived, the system enters a stalling phase during which the length of any silent periods in the first data flow are stretched. As the point in the first data flow at which the second data flow is necessary gets closer, the factor by which silent periods are stretched increases exponentially. Once the expected second data flow in fact arrives, playback of two data flows is accelerated by compressing silent periods so as to clear the backlog of additional data that built up in the buffer during the stalling phase.

A method, system and computer program for automatically launching a target application based on characteristics of a selected string of characters in a source application includes the steps of receiving a command resulting from a user's action, selecting a string of characters in a source application; identifying among one or a plurality of predefined regular expressions, a regular expression matching the selected string of character; identifying a predefined data type previously associated with the source application and the regular expression matching the selected string of character; identifying a predefined target application previously associated with the identified data type and the source application; and launching the target application.
摘要:
A method of transmitting a web object over a broadcast standard channel to a remote mobile device, the method comprising the steps of accessing one or more web objects from a web server, wherein each web object has an address, determining a hierarchy and an address linkage pattern for the one or more web objects, identifying a closed web site from the one or more web objects, translating the address of one of the web objects in the closed web site to an indicator which is based on the hierarchy and address linkage pattern of the web objects; storing the closed web site such that the web object is stored with its associated indicator, and transmitting a required web object from the stored closed web site at a frequency and a repetition rate which is determined from the indicator.
