    摘要： Methods, systems, and apparatus, including computer programs encoded on a storage device, for triggering an alarm during a sensor jamming attack. In one aspect, a monitoring system sensor unit is disclosed that includes a sensor, a communication unit configured to communicate with a monitoring system using a range of frequencies, and a jamming detection unit. The jamming detection unit may include a processor and a computer storage media storing instructions that, when executed by the processor, cause the processor to perform operations. The operations include detecting a sensor jamming event, selecting a different form of communication other than the range of radio frequencies for the communication unit to communicate with the monitoring system, and providing, to the communication unit, an instruction to communicate with the monitoring system using the form of communication, wherein the communication unit may communicate, to the monitoring system using the form of communication, the sensor data.

    摘要： An object detection alarm system is provided for monitoring a protected area within a facility to ensure that it remains free of objects in accordance with federal, state, or local regulations or facility protocol. The system includes a housing supporting an ultrasonic sensor, a microcontroller, an alarm and a clock module. The sensor calculates time differentials between emitted and detected sonar signals and generates signals representing the calculated time differential values or a calculated distance based thereon, supplying those signals to a processor of the microcontroller which determines whether a violative condition is present based upon a comparison of the received signals and a pre-determined time differential value representing a non-violative condition. If a violative condition is determined, and persists for a period of time, the microprocessor activates an alarm until the condition is cleared. Also provided is a method of monitoring a protected area within a facility by means of an object detection alarm system as herein provided.

    摘要： In some implementations, a wireless sensing system may receive sensor data associated with an asset. The sensor data may be associated with a tampering event and the tampering event may include an action performed on the asset. The wireless sensing system may further determine whether the tampering event is performed by an authorized user of the wireless sensing system. The wireless sensing system may further determine whether the tampering event is performed within an authorized location of the wireless sensing system. The wireless sensing system may transmit a notification to a user of the wireless sensing system. The notification may alert the user of the wireless sensing system that the tampering event has occurred.
