Abstract: A method and a management server located in the cloud, for enabling adaptive power management in a gateway system, are described. The management server receives, from the gateway system powered by a rechargeable battery that is coupled with a solar power source, a location measurement indicating the location of the gateway system at a first time. The management server determines a solar profile indicating a measure of the power expected to be generated by the solar power source at the location during an interval of time that occurs after the first time. The management server transmits the solar profile to the gateway system causing the gateway system to determine based on a current battery level of the rechargeable battery and the solar profile an optimal power usage plan for the gateway system and to operate according to the optimal power usage plan during the interval of time.

Abstract: Methods and systems for offload of data from a wireless sensing device to a gateway device. A certificate that is generated by the management server in response to a determination that the gateway device is associated with a wireless sensing device is received during an initial connection with the management server. In response to confirming, based on the certificate, that the gateway device is authorized to connect to the wireless sensing device, the certificate is transmitted to the wireless sensing device; and data is received from the wireless sensing device in response to confirming that the wireless sensing device is authorized to connect with the gateway device based on the certificate.

Abstract: Controller devices may be configured to automatically connect to a remote management server (e.g., a “cloud”-based management server), and may offload received data and analyses to the remote management server via wired or wireless communications. The controller devices may further communicate with the management server, user computing devices, and/or human machine interface devices, e.g., to provide remote access to the controller device, provide real-time information from the controller device, receive configurations/updates, provide interactive graphical user interfaces, and/or the like.

Abstract: A method and apparatus for automatically determining that delivery of an untagged item occurred are described. Data is received, from a gateway device located on a vehicle on which the untagged item is transported, where the data includes data collected by the gateway device from a set of devices external to the gateway device. A determination of whether the vehicle stopped is performed based on a first part of the data pertaining to the movement of the vehicle. Automatic determination of whether offload of cargo from the vehicle occurred, is performed based on a second part of the data, which is consistent with activity indicative of the offload of cargo from the vehicle as opposed to data collected based on a tag on an item. Responsive to determining that the offload of cargo from the vehicle occurred, a report including information to be used as proof of delivery is transmitted.

Abstract: A method in a wireless sensing device for authenticating a gateway device of a sensor network is described. The method includes receiving a certificate where the certificate was generated by the management server upon a determination that the gateway device and the wireless sensing device are associated and is a digital document including data and a digital signature, where the digital signature was generated by the management server based on the data and a private key of the management server, and where the data includes a first identifier and a second identifier; confirming that the wireless sensing device is authorized to upload data to the gateway device; in response to the confirming that the wireless sensing device is authorized to upload data to the gateway device, uploading to the gateway device data indicative of a plurality of sensor measurements taken over time to be transmitted to the management server.

Abstract: A set of certificates are received at a gateway device from a management server, where each one of the certificates was generated by the management server upon determination that the gateway device is associated with a respective wireless sensing device (WSD). The gateway device receives from a first WSD an advertisement message indicating it is available for connecting to a gateway device. In response to confirming based on a first certificate of the set of certificates associated with the first WSD, that it is authorized to connect to the WSD, the gateway device transmits to the first WSD the first certificate and an identifier of the gateway device for enabling authentication of the gateway device at the WSD. The gateway device receives data from the first WSD, upon confirmation at the WSD that it is authorized to connect with the gateway device.

Abstract: Methods and systems for secure data offload in a sensor network. The method comprises offloading data indicative of sensor measurements from a wireless sensing device to a gateway device through a first secure communication channel; and storing the data at the gateway device if there is not currently a second secure communication channel established between the gateway device and the management server. The method continues with offloading the data to the management server when the second secure communication channel is established; and reconciling the data at the management server to generate reconciled sensor measurements in which duplicates have been removed.
