Cargo radar housing

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.

Tamper detection for intrinsically-safe or explosion-proof enclosures

Visor accessory for a sensor

A method at a sensor apparatus, the method including calculating a value for a target function based on at least one sensor of the sensor apparatus; determining that the value of the target function is within a defined threshold range for a defined time period, thereby finding an in-flight state for the sensor apparatus; and turning off transmission from a radio of the sensor apparatus based on the in-flight state.

Method and system for moving status detection for a sensor apparatus

Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.

A method for updating communication parameters on a mobile device, the method including sending a communication from the mobile device to a server, the communication including a location of the mobile device; receiving at the mobile device, responsive to the communication, a new communication parameter; reconfiguring the mobile device with the new communication parameter; and sending a second communication from the mobile device to the server, the second communication using the new communication parameter.

Method and system for dynamic APN selection

Tilt bracket set

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.

Method and system for cargo loading detection

A method at a computing device, the method including obtaining sensor data for a vehicle providing vibration frequency and magnitude; calculating an energy for each of a low frequency passband and a high frequency passband of a bandpass filter pair; finding an energy ratio based on the energy for the low frequency passband and the energy for the high frequency passband; applying weighting constants to each of the energy for the low frequency passband, the energy for the high frequency passband and the energy ratio to calculate a decision variable; and finding that the vehicle is unloaded if the decision variable is below a threshold and finding that the vehicle is loaded if the decision variable is above a threshold.

Method and system for shipping container loading and unloading estimation

A method for pairing a first computing device with a second computing device, the method including: detecting motion at the first computing device; determining, at the first computing device, that a pattern of the detected motion corresponds with a saved motion pattern; and activating a communications subsystem on the first computing device based on the determining to begin a pairing process.

Method and system for pairing a chassis and container in an asset tracking system

A method and system for determining the weight of a load when the load is placed on a chassis supported by a spring suspension. The method comprises measuring a first distance to a position fixed relative the ground by at least one sensor mounted on the chassis; detecting a displacement of the chassis relative to the position based on the first distance and a second distance measured to the position by the at least one sensor; determining the weight of the load on the basis of the chassis displacement; and communicating the determined weight of the load. The system comprises at least one sensor mounted on the chassis for measuring a first distance to a position fixed relative to the ground; a module for detecting a displacement of the chassis relative to the position based on the first distance and a second distance measured to the position by the at least one sensor, the module determining the weight of the load on the basis of the chassis displacement; and a communication module for communicating the determined weight of the load.
