摘要： A system and method manages power in a wireless micro-sensor having a self-contained energy source. The system and method identify the rated capacity of the self-contained energy course by processing an identification value of the self-contained energy source and measuring the temperature of the self-contained energy source over time. The system and method determine temperature trends, measure the depth of discharge of the self-contained energy source, and control the asynchronous transmission of the micro-sensor. The transmission occurs in response to the measured temperatures, the determined temperature trend, and the depth of discharge of the self-contained energy source.

摘要： A low magnetic interference battery is provided, the battery insertable into a mobile communication device, the mobile communication device comprising a radio interconnected with a microphone and a receiver. The battery comprises a battery portion enabled to provide electrical power to the radio, the battery portion emitting a magnetic field when in operation. The battery further comprises a sealing portion for sealing the battery portion therein such that the battery portion is protected from moisture, the sealing portion comprising a magnetic shield portion arranged relative to the battery portion such that magnetic flux from the battery portion is routed away from the receiver when the battery is in operation in the mobile communication device.

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.

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.
