Abstract: A cable system for a truck trailer with connectors having a main power connection, a ground connection, and one, two, or more communication cable connections. Connectors include at least a power and ground connection for electrically connecting an individual trailer to the cable system. A master control circuit may be included in the trailer nosebox, and the master control circuit configured to send commands to slave control circuits mounted within the connectors. The slave control circuits in the connectors are configured to receive a control command sent by the master control circuit that may include an address, mode identifiers, or other indications of which connectors in the cable system should take action, and what actions should be taken.

Abstract: A rear collision warning device for trailers that may include one or more sensors, a control circuit, and one or more warning devices. In one aspect, the sensors are configured to monitor a predetermined zone behind and/or alongside a trailer and to optionally trigger warnings as predetermined criteria are satisfied. In another aspect, the control circuit controls the warning devices to emit a warning signal in the form of flashing lights, strobes, audible alarms, and the like, or to send warning notifications to a remote server, an app, or to a cab mounted display. The sensors, circuits, and warning devices are optionally mounted together in a separate housing and mounted at or near the side and/or rear of the trailer.

Abstract: A cable system for a truck trailer for reducing the number and/or size of wiring in a commercial trailer cable system from seven to four, three, or two, while also facilitating bidirectional communication with all connected electronic devices in the trailer. The cable system has a ground cable, a power cable, and zero, one or two additional communication cables that may carry analog and/or digital communications between the control circuit and components of the trailer such as turn signal lamps, brake lamps, backup cameras, environmental sensors, and the like. A transformer for increasing the voltage on the power cable is disclosed, allowing the power and ground cables to be smaller without reducing power delivered to the trailer.

Abstract: A communication system for a truck and trailer that may include trailer components electrically connected to a modulation unit. The modulation unit may be configured to encode trailer-related data values representing aspects of the trailer components such as operational status, failure of internal components, component operating parameters, and the like. The communication system may also include one or more light emitters responsive to the modulation unit that may be arranged and configured to direct light away from the trailer and toward one or more sensors electrically connected to demodulation units. The sensors may be responsive to the modulated light emitted by the emitters and the demodulation units may be useful to decode and obtain the trailer-related data values.

Abstract: A communication system that utilizes a light strip to carry data using the power and ground connections of the light strip. When used in the context of a truck and trailer, the system may include a sensor node configured to obtain status information about trailer components, and a data hub for collecting the information. The data about the trailer components may be transferred from the sensor node to the data hub using the power and/or ground connections of the light strip. The sensor node may communicate using the light strip by changing the current level of the light strip power connection, and these changes in the current level may be used by the data hub as a signal by which the data may be received.
