摘要:
A base station (e.g., a central device including a transducer assembly of one or more orthogonal transducers) transmits a magnetic field at a known power level and direction. The magnetic field signal includes data information transmitted from the base station to a movable remote station. The remote station includes a transducer assembly of one or multiple transducer coils to receive the magnetic field generated by the base station. Location and orientation of the remote station (with respect to the base station) are determined based on the magnitude, amplitude, and/or phase of magnetic field signals received on each of the remote station's transducers. The remote station may transmit the location and orientation information (e.g., raw measured data or converted data) to the base station using the same coils as used by the remote station to receive the magnetic field generated by the base station.

The data reception apparatus includes a main processing unit that waits in a standby state so as to be able to receive the connection signal that is transmitted in a first communication mode, and further receives, after reception of the connection signal, the data signal that is transmitted in a second communication mode that is different from the first communication mode; a sub processing unit that is provided in addition to the main processing unit, the sub processing unit being capable of receiving the data signal that is transmitted in the second communication mode; a notification unit that is capable of notifying information to a user; and a notification control unit that controls the notification unit so that the notification unit notifies a communication error to the user if the sub processing unit has received the data signal although the main processing unit has not received the connection signal.

Contents of one or more received messages can be analyzed to determine whether a transceiver device generating the inductive field has already been programmed with a unique communication code. If not, bidirectional communications can be established to program the transceiver device with a unique communication code over an inductive link. Orientation or position of a transceiver device can be used to initiate a process for programming a communication code. Generally, the communication code can define a unique relationship between two or more transceiver devices.

One aspect of the present invention is generally directed towards a system and method of tuning a transducer for transmitting and receiving a wireless signal. In an illustrative embodiment, a single transducer is coupled to a first or second circuit for either transmitting or receiving, respectively. Generally, electrical characteristics of the first circuit are adjusted to increase a magnetic field generated by the transducer. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal.

A system wherein a mobile terminal can control the operation of an external communication device using wire/wireless local-area communication. The mobile terminal includes a local-area wireless communication module, and acts to perform the local-area wireless communication using the local-area wireless communication module. The communication device accesses an Internet communication network in response to an Internet access command input thereto to perform wire Internet communication. A wire/wireless data format conversion device is provided to perform the local-area wireless communication with the mobile terminal and wire communication with the communication device, and, in order to enable communication between the mobile terminal and the communication device, convert the format of received data into a format recognizable by a destination device, said destination device being one of the mobile terminal and communication device, and send the resulting data to the destination device over a corresponding transmission channel. The wire/wireless data format conversion device, upon receiving the Internet access command from the mobile terminal, converts the format of the received Internet access command into one recognizable by the communication device and sends the resulting Internet access command to the communication device and, upon receiving Internet access result information from the communication device, converts the format of the received result information into one recognizable by the mobile terminal and transmits the resulting result information to the mobile terminal.

An apparatus for quick control of portable phone infrared transmission. The apparatus includes an input module, an information process module, a data storage module, an infrared module, and a display module. The information process module couples to the input module to receive an infrared control signal, determines whether the portable phone is in standby mode, and sends an access signal, an infrared enable signal and a display signal to the data storage module, the infrared module and the display module respectively if the portable phone is in standby mode. Then, the data storage module accesses data, the infrared module receives/transmits the data and the display module displays the data or related information.

A number dialing kit for a mobile phone includes a keypad unit and a processor unit. The keypad unit is operable so as to generate a dial number output. The processor unit includes a flow control analyzer, a communications protocol controller and an infrared transceiver. The flow control analyzer receives the dial number output from the keypad unit, and establishes program instructions for controlling the mobile phone to dial an input telephone number. The communications protocol controller receives the program instructions from the flow control analyzer, and configures the same into a format that complies with a predetermined infrared communications protocol. The infrared transceiver establishes an infrared transmission link with the mobile phone, and transmits the program instructions configured by the controller to the mobile phone.

A private radio switching system comprises at least one cordless handset that interfaces with the main switching apparatus of the switching system via a base station connected with the main switching apparatus. The private radio switching system also includes at least one main telephone set having a plurality of functions. The main telephone set is not connected with the main switching apparatus and does not have a wired handset. Instead, the cordless handset and the main telephone set interface with each other. Data generated by the cordless handset relating to handset operations is transmitted to the main telephone set by infrared ray (IR) or by other wireless data communication. The main telephone processes the data and displays a message on the display of the main telephone set that corresponds to the operational data. Data entered by the telephone main set is transmitted to the cordless handset by IR or other wireless data communication. The cordless handset is operated according to the data entered at the main handset.

The invention relates to a system which allows the transfer of data between first and second remote locations. In one embodiment the transfer is between apparatus in the form of telephone apparatus at each location. In a second embodiment the transfer of data is performed via apparatus in the form of two broadcast data receivers allocating the data as part of an e-mail transmission, but in both cases the data is transferred between a device and apparatus at the first location and subsequently from the apparatus to apparatus at the second location via a telecommunications link, where the data is typically transferred from the apparatus at the second location to a further device.
