An electronic device is disclosed. The electronic device comprises a first communication unit, a second communication unit, and a processor for performing control such that the second communication unit operates in a scan state in which an undirected advertising packet can be received when a preset IR signal is received from a remote control device through the first communication unit, acquiring identification information of a target device from the undirected advertising packet when the undirected advertising packet is received from the remote control device in the scan state, and providing a user interface (UI) for guiding a Bluetooth connection with remote control device when the acquired identification information of a target device matches identification information of the electronic device.

A distributed network system can include a master controller having a master clock configured to output a master time, and a master transmission delay time module configured to modify the master time to add a known master transmission delay to the master time to output an adjusted master time. The system can include a first device operatively connected to the master controller and configured to receive the adjusted master time from the master controller.

Systems and methods described herein leverage dependence relationships between sensor readings to facilitate rapid detection of erroneous sensor readings and rapid response times when accurate sensor readings indicate events that call for remedial action. When a target sensor reports a questionable sensor reading, systems described herein can query additional sensors whose readings share expected dependence relationships with readings from the target sensor. Systems described herein determine whether the questionable sensor reading is trustworthy based on the expected dependence relationships and additional sensor readings received from the additional sensors. If the questionable sensor reading is trustworthy, the system can trigger appropriate remedial action and increase query rates for the additional sensors (and the target sensor) to monitor an underlying event more closely. If the questionable reading is not trustworthy, the system can trigger appropriate remedial action (e.g., by deactivating the sensor or sending an alert to an administrator).

A reproduction apparatus according to an embodiment of the present technology is a reproduction apparatus capable of executing synchronous reproduction of audio content with a different reproduction apparatus, the reproduction apparatus including: an illumination unit; an acquisition unit; a generation unit; a transmission unit; and a synchronization control unit. The acquisition unit acquires audio information. The generation unit generates illumination control information associated with the acquired audio information. The transmission unit transmits, to the different reproduction apparatus, synchronization control information that includes the audio information and the illumination control information. The synchronization control unit executes synchronous reproduction of the audio content with the different reproduction apparatus and synchronous control of the illumination unit, on the basis of the synchronization control information.

The present invention relates to a system for performing phase detection and synchronization in an AMI communication network using a relay communication, and a method thereof. According to an embodiment of the present invention, a system for performing phase detection and synchronization in an AMI communication network using a relay communication includes an AMI server for collecting a ‘reference zero-crossing detection (ZCD) time difference by phase’ of input/output terminals of a main transformer installed in a substation; and a data concentration unit (DCU) comparing the ‘reference ZCD time difference by phase’ transmitted from the AMI server with a ‘ZCD time difference by phase’ collected by itself, and matching the same to have a time difference close to an error range.

A data-transmission system, comprising measurement means, having memories, to create and collect measurement data, an output device having a zero-power passive state, to show in the zero-power passive state, machine-readable code containing the measurement data created using the measurement means, a power supply for the output device and the measurement means, a server arrangement to process and/or store the measurement data, and one or several reader devices to read the code from the output device in the zero-power passive state and arranged for data transfer with the server arrangement. The output device and measurement means with memories are to be arranged at monitoring objects.

Providing collision avoidance protection to controllers sharing the same sensor. Each of a pair of asynchronous controllers changes the period of a sync pulse transmitted to the other controller to indicate to the other controller it is synchronized. When one of the controllers begins reading data from the shared sensor, the other controller waits to receive another sync pulse for indicating when the controller is finished reading data from the shared sensor. Thus, the asynchronous controllers avoid accessing the same sensor at the same time.

A time synchronizer receives UTC (Coordinated Universal Time) time in serial+PPS (Pulse Per Second) format from a GPS (Global Positioning System) device and outputs timestamp data in multiple formats, including: CAN (Controller Area Network), Ethernet, gPTP (generic Precision Time Protocol), and serial+PPS. Multiple data sources receive timestamp data in the multiple formats and each provide data in a unified UTC time base to a sensor-fusion device. The unified UTC time base is based on the timestamp data in the multiple formats output by the time synchronizer. The time synchronizer may perform edge detection for a first transition of an internal clock signal following a transition of the PPS signal received from the GPS device. The internal clock signal may be asynchronous with the PPS signal received from the GPS device. The internal clock signal may have a frequency of 40 MHz.

Systems, methods, and apparatuses are discussed that enable robust, high-speed communication of sensor data. One example system includes a sensor bus, an electronic control unit (ECU), and one or more sensors. The ECU is coupleable to the sensor bus and configured to generate a synchronization signal, and is configured to output the synchronization signal to the sensor bus. The one or more sensors are also coupleable to the sensor bus, and at least one sensor of the one or more sensors is configured to sample sensor data in response to the synchronization signal and to output the sampled sensor data to the sensor bus.
