    Abstract: PROBLEM TO BE SOLVED: To prevent other party from intercepting conversation of people in the vicinity of a voice data link by allowing the receiver to have a processor that converts a voice signal having transaction data into an electric signal and extracts the transaction data from the electric signal and a filter that eliminates part of signals of voice of people which may be received by the microphone. SOLUTION: A voice data receiver 10 prevents leakage of conversation of people in the vicinity of a voice data link formed between a receiver 10 being part of a radio acquisition device 110 and a voice signal source 10a. A microphone 14 transduces a sound wave into an electric signal through the transmission of data to other processor or through data processing in a processor 14a contained in a radio wave acquisition device 110. The arrival of the voice signal to the processor 14a is prevented and interception is inhibited by using a voice filter 16 before the microphone 14 or an electric filter 17 after the microphone 14.

    Abstract: PROBLEM TO BE SOLVED: To simplify the position detecting work of a misfiled document by displaying the position of a label when a response code is transmitted to an interrogator, and consequently displaying the position of the document mounted thereon. SOLUTION: After an electronic label 15 is mounted on a document, and the response code of the label and the document information are recorded, the document is filed in a proper document recording device such as filing cabinet. When the response code of the label 15 is inputted to an interrogator 20 in order to detect the position of the labeled document 10 within the recording device, one of the label 15 and the interrogator 20 shows the position of the label or the position of the document 10 according to the specified electronic form of the label and the interrogator 20. By use of this method, the position of an improperly filed document can be detected in an organized document filing system.

    Abstract: The present invention provides a method is provided for soft vertical handovers. The method includes requesting a handover from a first wireless network that operates according to a first protocol to a second wireless network that operates according to a second protocol, the first protocol being different than the second protocol, via a first wireless telecommunication link that operates according to the first protocol. The method also includes forming, in response to the handover request, a second wireless telecommunications link according to the first and second protocols, the second wireless telecommunications link being concurrent with the first wireless telecommunication link. The method further includes dropping the first wireless telecommunications link after forming the second wireless telecommunications link.

    Abstract: Methods and systems for locating objects are disclosed. An electronic tag is attached to an object before storing the object. The electronic tag is identifiable by a unique response code. The response code and information pertaining to the object are recorded and the object may then be stored. To locate the object, the response code is entered into an interrogator. The interrogator sends a signal that causes the tag to emit a sound. The system thus allows for random storage of objects and is also useful for locating misplaced objects.

    Abstract: Se describe un sistema para generar avisos audibles en una instalacion, que tiene, en un aspecto de la presente invencion, un teléfono de instalacion conectado en una línea telefonica de la instalacion, que forma los primeros y segundos canales de comunicacion. El primer canal de comunicacion está adaptado para su conexion y comunicacion a un red telefonica. Un controlador de avisos se conecta en la línea telefonica y genera señales de avisos audibles a lo largo del segundo canal de comunicacion al teléfono de la instalacion, el cual recibe loa avisos audibles correspondientes. Un conmutador se puede conectar operativamente entre el teléfono de la instalacion y el controlador de avisos y conmuta el controlador de avisos al segundo canal de comunicacion para transmitir señales de avisos audibles al teléfono de la instalacion. En otro aspecto de la presente invencion, los avisos audibles se generan a lo largo del segundo canal de comunicacion al altavoz, sin el uso de un conmutador.
