Automatic provisioning of Wi-Fi connections for trailers

In one embodiment, a device of a tractor unit determines that the tractor unit is connected to a trailer via physical cabling. The device sends, via the physical cabling, a powerline communication (PLC) message to the trailer that includes a service set identifier (SSID) and password for a Wi-Fi transceiver of the tractor unit. The Wi-Fi transceiver of the tractor unit receives an association request sent wirelessly from a Wi-Fi transceiver of the trailer that is based on the sent SSID and password. The device establishes the Wi-Fi transceiver of trailer as a Wi-Fi client of the Wi-Fi transceiver of the tractor unit.

Communication device and communication signal generation method

The communication device includes a selection unit a selection unit which selects a mode that prescribes a number of one or more channels prepared in a prescribed frequency band used for a communication to be performed with another communication device via a wired medium and a channel to be used for the communication in the mode; and a signal processing unit which generates communication frames to be used for the communication by performing signal processing on input data according to the selected mode and channel.

Detecting actuation of electrical devices using electrical noise over a power line

Activity sensing in the home has a variety of important applications, including healthcare, entertainment, home automation, energy monitoring and post-occupancy research studies. Many existing systems for detecting occupant activity require large numbers of sensors, invasive vision systems, or extensive installation procedures. Disclosed is an approach that uses a single plug-in sensor to detect a variety of electrical events throughout the home. This sensor detects the electrical noise on residential power tines created by the abrupt switching of electrical devices and the noise created by certain devices while in operation. Machine learning techniques are used to recognize electrically noisy events such as turning on or off a particular light switch, a television set, or an electric stove. The system has been tested to evaluate system performance over time and in different types of houses. Results indicate that various electrical events can be learned and classified with accuracies ranging from 85-90%.
