    摘要： A method for testing a network connection of an emergency response system at least including a remote device and a central station includes: receiving, by the remote device, a user's instruction or an automatically triggered event for initiating a test of the network connection between the remote device and the central station; in response to the user's instruction or the automatically triggered event, sending, by the remote device, a first test signal to the central station; receiving, by the remote device, a first response signal sent from the central station for acknowledging the first test signal; and in response to receiving no first response signal from the central station for acknowledging the first test signal, alerting, by the remote device, a user of the remote device about a failure of the network connection.

    摘要： Various embodiments of the teachings herein include a method for commissioning hazard detectors in a detector line. The method may include: operating a control center for the detectors for the installation and/or commissioning of the detectors in an installation mode; and in the case of an identified installation error, the control center sends a corresponding error message to the mobile communication terminal for display on an output apparatus of the mobile communication terminal and/or a corresponding error message for display on an output unit of the detector affected by the installation error; and checking the electrical properties of the detector line in the fire alarm control center.

    摘要： Concepts and technologies are disclosed herein for limiting service availability when a sensor device is non-operational due to a noise floor change. According to one aspect of the concepts and technologies disclosed herein, a connected home system includes a controller device configured to monitor a plurality sensor devices deployed within a premises, and a sensor device of the plurality of sensor devices. The sensor device can monitor radio frequency (“RF”) noise in a radio environment associated with the premises. The radio environment is associated with an RF noise floor. The sensor device can determine whether the radio frequency noise exceeds a noise threshold. In response to determining that the RF noise exceeds the noise threshold, the sensor device can cause the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold.

    摘要： A disconnection detection device for an in-vehicle device having a load circuit, is provided with a second wire harness which is arranged along at least a part of the first wire harness, a current circuit which supplies a current for disconnection detection to the second wire harness, and a disconnection determination circuit which monitors an output voltage of the current circuit so as to determine presence or absence of disconnection of the second wire harness. Disconnection of the second wire harness is detected as the disconnection of the first wire harness based on disconnection determination of the disconnection determination circuit.

    摘要： The invention relates to a bus system (1) comprising a control unit (2) and at least one bus node (3.1, 3.2, 3.3). The control unit (2) is allocated at least two data communication interfaces (2.1, 2.2) which are respectively designed to transmit and receive data. The at least one bus node (3.1, 3.2, 3.3) comprises a bus coupler having at least two data communication interfaces (3.11, 3.12; 3.21, 3.22; 3.31, 3.32) respectively designed to transmit and receive data. The control unit (2) and the at least one bus node (3.1, 3.2, 3.3) are respectively connected together via their data communication interfaces and corresponding two-point connections (8) to form a ring topology. The bus coupler of the at least one bus node is designed to directly and without delay transmit, and thus forward, data received at one of its at least two communication interfaces via its other data communication interface.
