摘要: The present application relates to a detection circuit for detecting a detector removal fault. The detection circuit comprises: a switching circuit. The switching circuit comprises one or more switching elements; an energy storage element; and a control circuit for controlling the energy storage element to discharge by controlling the one or more switching elements to perform an opening or closing action. The control circuit is configured to cause the energy storage element to discharge based on a first loop if the detector is removed from the diode bases, and to cause the energy storage element to discharge based on the first loop and a second loop including the terminal resistor if the detector is not removed from the diode bases. The control circuit is further configured to detect the detector removal fault based on an output voltage of the area monitoring module during discharge process.

摘要: An isolator circuit (25) for a unit of a safety system (10) includes a power control line (14) connectable to a first loop of a safety system and a power connection (16) connectable to a second loop of the safety system. A switch (26) is connected to the power control line (14), and the switch has a closed configuration and an open configuration. A controller (28) controls the configuration of the switch (26). If a voltage across the circuit (10) from the power connection (16) to the power control line (14) falls below a predetermined level, the controller (28) opens the switch (26), thereby causing a disconnection to occur in the first loop.

摘要: A depth data detection apparatus and monitoring apparatus are disclosed. The depth data detection apparatus has at least two infrared light generators (11, 12) alternately operating, thereby ensuring that each of the infrared light generators has a sufficient power-off time while ensuring continuous operation of the system, so that each infrared light generator can reach its service lift as much as possible. Different infrared light generators can project infrared beams with different angles and/or from different positions, and the depth information obtained can be fused with each other in order to acquire the depth information of the object to be measured more completely. In addition, different infrared light generators can also project infrared beams to different areas or the same area of the space to be measured for their respective purposes.

摘要: Various arrangements of smart devices and systems are presented. Such smart devices and systems may include a wireless interface, a light sensor that detects an ambient brightness level of an ambient environment of the smart device, a motion sensor that detects motion of a user in the ambient environment of the smart device, a light that is capable of outputting light into the ambient environment of the smart device, and a processing system. The processing system may cause the light to illuminate based on: the message indicating that the lighting feature has been activated; the ambient brightness level being below the threshold brightness value; and the user moving in the ambient environment of the smart device or system.

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 work order prediction system is described. The work order prediction system analyzes retrieved sensor signal activity records to compare counts of signal activity in defined signal groupings to corresponding predetermined thresholds of sensor signal activity and generates a report based on the comparison when sensor signal activity exceeds the determined threshold values. The predetermined thresholds of sensor signal are determined for each signal grouping by comparing corresponding groupings of service record activity against determined counts of historical sensor signal activity to establish threshold values for each of the groupings and produce a model based on the comparison of the historical sensor signal activity to service activity.
