摘要:
According to the present invention, a method for controlling a mobile terminal device is provided, wherein said device comprises a smartcard module and a near field communication module. In a first operation a smartcard operation on said mobile terminal device is started which results in an activation or switching on of said smartcard module. The smartcard application may be started by a user or based on the location of said mobile terminal device. That is the case for instance if the mobile terminal device is located in the area of a point of sales terminal, the smartcard application will automatically starts. Further, time controlled starting of certain applications is conceivable. Then it may be determined if said started smartcard application is an application for performing data transactions with external entities and in case of an affirmative determination a connection between said smartcard module and said NFC-module will be activated.

A communications device has a NFC communicator (15) having a coupler (17) to couple with a coupler of a near field RF communicator in near field range to enable communication of data between the communicators by modulation of a magnetic field, a demodulator (42) to extract modulation from a modulated signal coupled to the coupler and a modulator (40) to modulate an RF signal in accordance with data to be communicated by the NFC communicator. The device also has at least one secure element (30; 31) separate from the near field RF communicator (15) to provide secure data storage for transaction data representing or relating to a transaction. A controller controls operation of the NFC communicator, reads transaction data from the at least one secure element and causes the modulator to modulate an RF signal in accordance with transaction data read from the at least one secure element so as to communicate the read transaction data to a near field RF communicator in near field range as proof of the transaction to enable an action related to the transaction to be carried out.

A terminal for interacting with a signaling tag includes a controller capable of selecting a signaling tag and thereafter receiving a tag type from the signaling tag at least partially over an air interface. The controller is also capable of determining if the terminal is actively operating an application. In this regard, the controller is capable of performing a predefined action based upon the tag type, such as based upon a tag type of “Read Only,” “Read/Write” or “Transceiver in Show Mode.” And when the controller is actively operating an application, the controller is capable of performing the predefined action further based upon the application and a state of the application.
摘要:
Methods, systems, and devices for controlling electrical energy consumption in an electricity distribution network, so as to reduce net energy consumption in a given area during a given time period, are described. In particular, a method of controlling electrical energy consumption within an electricity distribution network is described. The method comprises maintaining a database of information about electric devices, and identifying a time period during which consumption of electrical energy is to be controlled. The method further comprises selecting, based on device profile information stored in the database, groups of electric devices, and associating one or more time intervals with each of the selected groups. Requests are sent to the electric devices of the selected groups to control electrical energy consumption and/or provision by the electric devices. This enables a reduction in net consumption of electrical energy during a respective time interval.

A near field RF communicator (100) has an inductive coupler (102) and a first signal provider (109, 110, 111) to cause the inductive coupler to provide a first signal that when inductively coupled to the inductive coupler of another near field RF communicator in near field range is insufficient to cause initiation of communication with that other near field RF communicator. A sensor (116) senses a change in an impedance of the inductive coupler (102) due to inductive coupling of the first signal between the inductive couplers of the said near field RF communicator and a said other near field RF communicator in near field range. A controller (107) determines whether or not another near field RF communicator is in near field range on the basis of any change in impedance sensed by the sensor and, if another near field RF communicator is determined to be in near field range, causes a second signal to be inductively coupled to the other near field RF communicator to initiate communication between the two near field RF communicators. The sensor may use a phase detector (118) to enable a change in impedance to be sensed by detecting a change in a current-voltage phase relationship resulting from a change in impedance.

A near field communicator has a driver (6) to supply a drive signal to drive an antenna (10) to generate a magnetic field. A magnetic field sensor (18) is located so as to be within a magnetic field generated by the antenna (6) to sense a magnetic field characteristic. A controller (17) provides a control signal to control the operation of the driver (6) to compensate for any difference between the magnetic field characteristic sensed by the magnetic field sensor (18) and a predetermined parameter.
摘要:
Methods and systems for measuring and/or managing power consumption by power units connected to an electricity distribution network are disclosed. Power flow to and/or from a power unit connected to an electricity distribution network is controlled in accordance with a control sequence, such that the consumption and/or provision of power by the power unit results in a power flow having a predefined flow pattern, and having a characteristic, such as an amplitude, which can be remotely measured. This measurement may be performed using a method in which a signal indicative of power flowing at a measurement node is measured and correlated with a predefined pattern, and a characteristic of the correlated signal is measured. Thus, power flow characteristics resulting from a group of one or more power flow devices can be remotely detected and measured.
