摘要： There is provided a fire alarm device including multiple light sources, a light sensor, a first processor and a second processor. In a standby mode, the first processor identifies whether to wake up the second processor according to a detection result of the light sensor obtained by detecting emission light of one of the multiple light sources. The second processor identifies whether to generate an alarm according to a detection result of the light sensor obtained by detecting emission light of the multiple light sources. The fire alarm device further includes a thermal sensor for providing detected temperature values to the first processor and/or the second processor to perform the identifying procedure.

摘要： The present invention relates to a method for generating an alarm pertaining to continuous biometric data and, more specifically, to an alarm generation method in which, if an alarm condition is satisfied, an alarm is output to a user while maintaining the alarm in an activated state during a set alarm period, and changing the alarm type selected by the user during the alarm period, thereby enabling the user to be prompted to input information or take an action in response to the alarm without ignoring the alarm, while not causing inconvenience to the user due to frequent alarms; and when the alarm condition is satisfied, an operating mode of a receiver is determined and the alarm type, which has been set in accordance with the alarm condition, is changed to an alarm type corresponding to the operating mode of the receiver, thereby making it possible to prevent an alarm from being generated against the user's wishes.

摘要： A system and method for configuring a security system using near-field communication devices that receive and transmit radio frequency signals is described. A first near-field communication device of the security system has a preset distance range. The security system communicates, using the first near-field communication device, with a second near-field communication device of a user device in response to the second near-field communication device being within the preset distance range of the first near-field communication device. The security system provides configuration information of the security system from the second near-field communication device to the first near-field communication device.

摘要： Various embodiments of a programmable barrier alarm are described. In one embodiment, a programmable barrier alarm comprises a magnet and a sensor, the sensor comprising a magnet and a sensor, comprising a magnetic field detector for sensing a magnetic field produced by the magnet and for producing an electronic signal based on the magnetic field, a processor, and a memory for storing alarm threshold values and processor-executable instructions that, when executed by the processor, cause the sensor to, in a calibration mode of operation, determine a value of a first electronic signal from the magnetic field detector when the barrier is in the closed position, calculate a first threshold value based on the first electronic signal, and calculate a second threshold value based on the first electronic signal, in a normal mode of operation, compare electronic signals from the magnetic field detector to the first and second threshold values, and generate an alarm signal if any of the electronic signals are less than the first threshold or greater than the second threshold.

摘要： Various apparatus and methods for smoke detection are disclosed. In one embodiment, a method of training a classifier for a smoke detector comprises inputting sensor data from a plurality of tests into a processor. The sensor data is processed to generate derived signal data corresponding to the test data for respective tests. The derived signal data is assigned into categories comprising at least one fire group and at least one non-fire group. Linear discriminant analysis (LDA) training is performed by the processor. The derived signal data and the assigned categories for the derived signal data are inputs to the LDA training. The output of the LDA training is stored in a computer readable medium, such as in a smoke detector that uses LDA to determine, based on the training, whether present conditions indicate the existence of a fire.
