摘要: A method at a sensor apparatus affixed to a transportation asset, the method including detecting a trigger at the sensor apparatus; taking a threshold number of samples of a displacement-related value of the transportation asset over time; determining that a variance of the threshold number of samples exceeds a threshold; analyzing a frequency property based on the threshold number of samples; and based on the frequency property, determining whether the transportation asset is loaded or unloaded.

摘要: An Internet of Things device and method for controlling the flow of power to a device through remote instructions. The device may include a battery and a switch coupling the battery to a main circuit, the switch including a sensor detecting a first condition. While detecting the first condition, the switch may be open-circuited, decoupling the battery from the main circuit. While not detecting the first condition, the switch is close-circuited, coupling the battery to the main circuit and providing power. The device may further include a controller coupled to a wireless communications module, which may receive instructions from a remote server. These instructions may instruct the controller to send a disable signal to the switch, preventing the switch from becoming open-circuited when the sensor detects the first condition.

摘要: Devices and methods for detecting and reporting a battery tamper event with regard to an intrinsically-safe or explosion-proof device while the device is located in a hazardous environment. The device may include a location sensor for determining that the device is in a hazardous location. While in the hazardous location, the device may detect an open enclosure event using a sensor and, if so, it may monitor for detection of a battery tampering event. The battery tampering event may include battery replacement or battery charging. The battery tamper event may be reported to a remote server over a wireless channel when it occurs.
