Abstract: A system for detecting moisture including: moisture sensors and a control module including a reader module, the control module is configured to: obtain a numerical value related to the feature of the selected response signal of the sensor element which is shielded against liquid; obtain a numerical value related to the feature of the selected response signal of the sensor element which is not shielded against liquid; determine a difference between the obtained numerical value related to the feature of the selected response signal from the sensor element which is shielded against liquid and the obtained numerical value related to the feature of the selected response signal from the sensor element which is not shielded against liquid; determine the detection of moisture if the determined difference is above or below a threshold. A method of detecting moisture is also provided.

Abstract: In an example method of target position estimation, the method includes calculating initial estimated positions of a target transmitter. Each of the initial estimated positions is based on an angle of arrival estimate received from a locator. The method includes generating an error projection associated with each of the initial estimated positions. The error projection is based on azimuth and elevation error characteristics of the locator associated with the initial estimated position. The method includes creating a select group of the locators based on overlaps of the error projections, wherein the select group of locators comprises a subset of the locators. The method includes calculating a refined estimate of the position of the target transmitter based on the initial estimated positions associated with the select group of locators.

Abstract: Methods and devices for synchronizing a device clock in a wireless network (e.g. a LPWAN) are disclosed. Example methods comprise identifying a device temperature, identifying a clock drift associated with the identified device temperature and applying a correction to the device clock based on the identified drift. For the identified device temperature, the drift is identified by comparing the confidence of the drift value in a pre-calibration curve generated from fixed drift values in a pre-calibration table with the confidence of the drift value in a learning curve generated from variable drift values in a learning table and selecting the drift value from the curve having the higher drift confidence.

Abstract: Method and apparatus for sending and receiving data in a wireless machine to machine communication network comprising at least a gateway (2) and a plurality of nodes (4), implementing an hybrid Medium Access Control protocol to access the shared medium. In order to prevent collisions when sending data transmissions (26), nodes (4) request access to the medium with access request packets (25), and are informed by the gateway (2) if said access request packets (25) are received correctly or if a collision occurred. According to the feedback information (24) provided by the gateway (2), nodes (4) are organized in a distributed queuing system with separate queues collision resolutions and data transmissions (26). Time slots (19) with fixed length are used, divided into three separate subperiods for feedback information (24), access request packets (25) and data transmissions (26). The method and apparatus further implements channel hopping to reduce interferences from adjacent networks.

Abstract: The heating of a surface is controlled by: monitoring the temperature of a plurality of zones of the surface to output at least one temperature reading of each of the plurality of zones. The temperature readings are modulated in response to a pattern arranged across a portion of the plurality of zones. The energy delivered to each of the plurality of zones is controlled based on the modulated temperature readings to maintain a substantially homogeneous temperature distribution across the surface.
