摘要:
An automotive communication method includes installing a sensor within a vehicle such that the sensor is submerged in a liquid during operation of the vehicle and/or substantially surrounded by a metallic structure during operation of the vehicle. A long wave magnetic signal is transmitted from the sensor. The signal is indicative of a condition sensed by the sensor. The signal is wirelessly received at a controller disposed within the vehicle. Receipt of the signal at the controller is responded to by adjusting a display and/or a setting within the vehicle.

A method for deploying and evaluating a network system includes providing an electronic two- or three-dimensional representation of a layout of a building, placing a plurality of nodes of the network system in the building, and communicatively coupling the nodes together to form the network system. The nodes are inspected dependent upon a regulatory requirement and/or the representation of the layout of the building. The network is evaluated dependent upon data collected during the inspecting and dependent upon a network protocol design and/or an interference model. The inspecting of the nodes and the evaluating of the network are performed automatically by use of at least one electronic processor.

An automotive electrical body system includes a plurality of electrical assemblies coupled to at least one automotive body component. Each of the assemblies includes a heating element for heating the at least one component, a motor for actuating the at least one component, or a switch configured to toggle the at least one component on and off. Each of the assemblies also includes a wireless communication module for receiving wireless signals, and, in response to the wireless signals, controlling operation of the heating element or motor. An electrical conductor interconnects each of the electrical assemblies and carries electrical power to each of the electrical assemblies.

Methods for operating real-time wireless networks enable robust medium access strategies for communicating nodes in the network. A given wireless channel is divided into several sub-carriers, with each node assigned to a subset of sub-carriers. A master wireless node uses different subsets of the sub-carriers to communication with two or more slave wireless nodes simultaneously. The method includes generation of preambles that are robust to interference and multipath conditions. The method also enables communication within a maximum predetermined latency bound.

A wind turbine condition monitoring system and method are disclosed where the wind turbines include a tower, a gearbox coupled to the tower, and turbine blades coupled to the gearbox. The monitoring system includes blade sensors coupled to the blades, a hub node coupled to the gearbox and a controller. The controller is in communication with the hub node and blade sensors, and determines blade positions based on blade sensor readings. The blade sensors and hub node can include multi-axis accelerometers. The controller can wirelessly communicate with the blade sensors directly or through the hub node. Using position information, shadowing areas with obstructed communication can be avoided, node separation can be accounted for to reduce power requirements and/or interference from multiple transmitters can be avoided during node communications.
