Abstract: The present application provides a gas alarm replacement warning method and device, and an electronic apparatus including the device. The method is applied to a gas alarm including a gas-sensitive element. The method includes: collecting signal data of the gas alarm; analyzing the current use state of the gas alarm based on the signal data; determining a dynamic model of the expected service life of the gas alarm according to the current use state, and calculating the expected use duration of the gas alarm; determining whether the actual use duration of the gas alarm is greater than the expected use duration; and if so, outputting a replacement prompt signal. Therefore, based on the expected service life of the gas alarm, when the use duration of the gas alarm approaches the expected service life, a replacement prompt signal is issued to solve the problem of untimely replacement of the gas alarm and ensure the safety of indoor gas use.

Abstract: A method for dynamically configuring a receiver of an object tracking system includes detecting an environmental or situation change with the tracking system, and transmitting, in response to the detected change, a signal to the receiver to switch from a first analog front end to a second analog front. The analog front ends may have antennas with different gain, or antennas with the same gain but different filters. The environmental change may be detected based on events per second received from the receiver. The situational change may be detected by determining a bounding region encompassing tracking-tag locations and identifying an optimum analog front end from a plurality of analog front ends of the receiver. A signal is then transmitted to the receiver to switch to the optimum analog front end. The optimum analog front end is the one analog front end having the greatest coverage of the bounding area.

An axis of the gyroscope can be collinear with an axis of the accelerometer. A method of inspecting a well pumping unit can include attaching a sensor assembly to the pumping unit, recording acceleration versus time data, and in response to an amplitude of the acceleration versus time data exceeding a predetermined threshold, transforming the data to acceleration versus frequency data. A method of balancing a well pumping unit can include comparing peaks of acceleration versus rotational orientation data to peaks of acceleration due to circular motion, and adjusting a position of a counterweight, thereby reducing a difference between the peaks of acceleration due to circular motion and the peaks of the acceleration versus rotational orientation data for subsequent operation of the pumping unit.

Abstract: A luminaire whose primary operation is to provide ambient or focused lighting in a hazardous environment is further configured to communicate, within the hazardous environment, alert and/or detected events or conditions via visual sequences. Different visual sequences uniquely identify respective alerts and/or detected conditions, which may include conditions occurring at the luminaire and/or conditions occurring within the hazardous environment. Different visual sequences are defined by respective blink sequences stored in a blink sequence library at the luminaire. Blink sequences are configurable, are distinguished by different amplitudes, frequencies, duty cycles, and other energization/de-energization waveform characteristics, and are applied to one or more illumination sources of the luminaire to thereby generate corresponding visual sequences in the hazardous environment.

Abstract: A vehicle has a detecting section that detects, as a detection value, a rotational angle of each wheel assembly. A transmitter provided in each wheel assembly transmits transmission data when the rotational angle of the wheel assembly is any of specific angles. At the performance of transmission at the specific angle, the transmitter changes data that is different from angular data indicating the rotational angle of the wheel assembly and is included in the transmission data in accordance with the specific angle. A vehicle-mounted receiver collects the detection values detected by the detecting section upon reception of the transmission data. The receiver collects the detection values for each piece of the transmission data transmitted at the same specific angle based on a manner in which data included in the received transmission data is changed in accordance with the specific angle.

Abstract: Examples provide a system and method for remote management of lockable devices associated with emergency vehicles. A lockable device is a device, such as a multicolor light device or a siren device having one or more available functions which are initially placed in a locked state at the time of manufacture. A user can unlock the locked functions by logging into a remote device manager on a user device while the locked device is connected to the user device. The user selects one or more locked functions to unlock. The remote device manager generates a unique unlock code for each locked function selected for unlock. The unlock code is returned to the user device for utilization in unlocking the selected functions. The unlock code enables operation of the locked function. A lock status is updated to indicate which functions have been unlocked.

Abstract: The disclosed embodiments relate to a system that determines whether an inferential model is susceptible to spillover false alarms. During operation, the system receives a set of time-series signals from sensors in a monitored system. The system then trains the inferential model using the set of time-series signals. Next, the system tests the inferential model for susceptibility to spillover false alarms by performing the following operations for one signal at a time in the set of time-series signals. First, the system adds degradation to the signal to produce a degraded signal. The system then uses the inferential model to perform prognostic-surveillance operations on the time-series signals with the degraded signal. Finally, the system detects spillover false alarms based on results of the prognostic-surveillance operations.
