Abstract: By deciding whether a beacon device is authentic based on a distance between a position, which is represented by current position information obtained by a handheld wireless terminal, and a position, which is represented by position-of-installation information registered in a server, fraudulent use of the beacon device can be prevented. Accordingly, reliability of a communication system including the beacon device is upgraded, and a service such as an electronic coupon can be safely provided.

Abstract: A positioning unit of a terminal device measures the current position and outputs current position information. A beacon signal receiver of the terminal device receives a beacon signal and acquires a beacon ID of a beacon device included in the beacon signal. A processing unit of the terminal device refers to a beacon position database so as to acquire a beacon ID associated with the current position information, and sets the beacon ID to be acquired by the beacon signal receiver in accordance with the acquired beacon ID.

Abstract: Data is safely transmitted or received between an electronic device and a communication terminal. The electronic device having a wireless communication capability transmits data, which is encrypted using a predetermined cryptographic key, to the communication terminal, and decrypts data, which is transmitted from the communication terminal, using the predetermined cryptographic key. The communication terminal capable of wirelessly communicating with the electronic device transfers encrypted data to or from the electronic device, and requests a security management server to encrypt or decrypt data. The security management server encrypts or decrypts data, which is transmitted from the communication terminal, using the predetermined cryptographic key, and transmits the data to the communication terminal.

Abstract: A communication system includes: a beacon device which is connected to an electronic appliance; and an information terminal. In the communication system, the beacon device retains in advance authentication information that is used when authentication of the electronic appliance under monitoring is performed and transmits a beacon signal including the authentication information, if the condition of the electronic appliance has changed. Moreover, in the communication system, the information terminal, upon receiving a beacon signal including the authentication information, performs authentication using the authentication information and informs its user of a condition of the electronic appliance for which the authentication is done.

Abstract: A receiver receives a beacon signal transmitted from a beacon device. A processing unit maintains an application in an operating state after a detection of entering or exiting a reception area of the beacon signal that satisfies a waiting condition until a predetermined time period has passed. A storage unit stores a comprehensive waiting condition and an individual waiting condition as the waiting conditions of the beacon signal, the comprehensive waiting condition comprehensively indicating the identification information different from one another, and the individual waiting condition individually indicating a single piece of the identification information. The processing unit causes the storage unit to store the identification information of the beacon signal as the individual waiting condition, in a case where the processing unit detects entering the reception area of the beacon signal that satisfies the comprehensive waiting condition.

Abstract: The present invention reduces the influence of stuck processing having occurred in an overall data communication system. Data generated by a generation section of a first apparatus is transmitted by a transmission section to a second apparatus at a predetermined transmission rate. A processing section of the second apparatus processes the data received. A processing speed calculation section of the second apparatus calculates a processing speed at which the data is processed in the processing section. A notification section of the second apparatus notifies the first apparatus of the processing speed. A rate setting section of the first apparatus calculates a proper rate for transmitting the data to the second apparatus on the basis of a data processing speed in the second apparatus and performs setup so as to transmit the data to the second apparatus at the proper rate.

Abstract: A code for authentication is shared between or among a plurality of transmitting devices or a plurality of receiving devices in a transmit/receive system which implements authentication using a code between transmitting and receiving devices. Each transmitting device includes a variable code retaining unit, a control signal transmitting unit, a variable code updating unit, and a unit for transmitting variable code for synchronization. The variable code retaining unit retains a variable code. The control signal transmitting unit transmits a control signal including a variable code. The variable code updating unit updates the variable code after transmission of the control signal. The unit for transmitting variable code for synchronization transmits the updated variable code to other transmitting devices of the plurality of transmitting devices to allow the other transmitting devices to set such code as the latest variable code.

Abstract: An improved lighting control system, method, and terminal is disclosed. A lighting control system includes a plurality of lighting devices and at least one terminal. Lighting devices include a state retainer that retains the state of its own device, a lighting identifier retainer that retains the identifier of its own device, a control instruction detector that detects a control instruction issued to its own device and updates the state retained in the state retainer into a state in accordance with the control instruction, a light emitter that emits light according to the state retained in the state retainer, and a response signal transmitter that transmits a response signal, which contains the state retained in the state retainer and the identifier retained in the lighting identifier retainer. These and other embodiments and details, as well as embodiments and details of the terminal, are more fully disclosed herein.

Abstract: To accurately determine the nearest electronic device in establishing a pairing with an electronic device to be a target for remote control. A terminal device includes a received signal strength acquiring unit, a device selection processing unit, and a connecting unit. The received signal strength acquiring unit receives a signal transmitted from a plurality of electronic devices and acquires the electric field strength of the received signal. The device selection processing unit selects an electronic device to be a target for connection from the plurality of electronic devices in accordance with a normalized electric field strength that is a value obtained by normalizing the electric field strength of the received signal using a parameter corresponding to and unique to an electronic device that transmits the received signal. The connecting unit establishes a connection with the electronic device selected at the device selection processing unit.

Abstract: Techniques, systems and computer program products are disclosed for providing sensor mapping. In one aspect, a method includes receiving input from a user. The received input includes at least one of motion, force and contact. In addition, a sensor signal is generated based on the received input. From a choice of data structures a data structure associated with a selected application having one or more functions is identified. The data structure indicates a relationship between the generated sensor signal and the one or more functions of the selected application. The generated sensor signal is selectively mapped into a control signal for controlling the one or more functions of the selected application by using the identified data structure.
