    摘要: A piezo sounder device 100 comprising a piezo sounder 110 and a controller 120, wherein the controller 120 is configured, upon activation of the piezo sounder device 100, to drive the piezo sounder 110 at: a first frequency substantially corresponding to a resonant frequency of the piezo sounder 110 at a first operational temperature; and a second frequency substantially corresponding to a resonant frequency of the piezo sounder 110 at a second operational temperature. Also disclosed is a method 200 of manufacturing the device 100, and a method 300 of emitting a sound 400, 500.

    摘要: An outdoors fire alerting device, including a first part and a second part spaced apart from one another by a thermoelectric generator unit, the first part being shaped for insertion into a static object and the second, exposed part intended for being exposed to the ambient environment while the first part is retained within the static object; the first part, the second part and the thermoelectric generator unit being integrally coupled to one another, the thermoelectric generator unit being configured to generate electrical energy in response to a temperature difference between the first part and the second part, an alerting unit electrically coupled to the thermoelectric generator unit and configured to transmit a signal indicative of fire alert when the temperature difference between the first and the second part reaches a predefined value, where the first part has a generally cylindrical shape and is elongated along a first axis, where the first part is axial symmetric about the first axis.

    摘要: A method of controlling an agricultural facility for housing a plurality of animals includes the step of regulating the environment within the agricultural facility with an automated building operational system. An automated thermal event controller is operationally coupled with the automated building operational system and generates a thermal event signal in response to a thermal event in progress, whereby the automated thermal event controller, upon receipt of the thermal event signal indicating that the thermal event is in progress, activates an alarm state. In the alarm state, the automated thermal event controller: sends an alarm signal to a system administrator; places the automated building operational system in a safety-mode condition for a first predetermined time interval; and places the automated building operational system in a normal-mode operational condition after the first predetermined time interval and if a confirmatory signal is not yet then received from the system administrator.

    摘要: An evacuation guidance system is configured from multiple sensor modules, network lines, guidance indicators, and a guidance control device. Each sensor module includes multiple input/output port pairs, fire detection sensors, and a data control unit. The multiple input/output port pairs are connected to input/output port pairs of other sensor modules by means of network lines, thereby configuring a mesh-like autonomous network. The data control unit generates and outputs fire data after adding fire location data; upon receiving fire data, outputs the fire data after adding its own route flag; and stops the output of fire data when the fire data contains its own route flag. Upon identifying the location of the fire outbreak from the fire data, the guidance control device calculates optimum evacuation routes and causes the guidance indicators to turn on/off or flash.
