Abstract: A smart trailer system coupled to a trailer of a vehicle includes a sensor configured to measure a parameter of the trailer, a sensor interface board electrically coupled to the sensor and configured to retrieve the measured parameter, and a master controller communicatively coupled to the sensor interface board via a data bus.

Abstract: A system and method is provided to lock or unlock a gladhand coupler on a towed asset to prevent connection of a tractor air line to the gladhand is provided. The system prevents the tractor from properly operating the towed asset brakes and therefore prevents the unauthorized movement of the towed asset. The system has a locking mechanism that blocks the surface on the gladhand used for coupling with another gladhand coupler.

Abstract: A gladhand assembly includes a gladhand that rotates about a first axis with respect to a sealed housing. The sealed housing includes a lever affixed to the first axis to rotate as the gladhand rotates. A stop within the sealed housing may be configured into an engaged position in which it engages with the lever to lock the gladhand into a fixed position in which the gladhand cannot be rotated about the first axis. In addition, the stop may be configured into a retracted position to permit the lever to rotate and allow the gladhand to be rotated into a deployed position.

Abstract: A smart trailer system coupled to a trailer of a vehicle includes a sensor configured to measure a parameter of the trailer, a sensor interface board electrically coupled to the sensor and configured to retrieve the measured parameter, and a master controller communicatively coupled to the sensor interface board via a data bus.

Abstract: A method for traffic management of proprietary data, in a network system comprising a gateway and a sensor communicatively coupled to the gateway via a data bus, includes determining, by a processor of a bridging device, whether a dedicated pipeline for transmission to the gateway is available, in response to determining that the dedicated pipeline is available, transmitting, by the processor, a request for the dedicated pipeline, determining, by the processor, whether the dedicated pipeline has been established between the bridging device and the gateway, and in response to determining that the dedicated pipe has been established, requesting, by the processor, the proprietary data from the sensor, transmitting, by the processor, the proprietary data from the sensor to the gateway via the dedicated pipeline, and transmitting, by the processor, a dedicated pipeline release signal to the gateway indicating release of dedicated pipeline between the bridging device and the gateway.

Abstract: A vehicle vision system including an isolation block configured to compress under pressure, a rigid block on an interface surface of the isolation block configured to distribute pressure across the interface surface of the isolation block, the rigid block including a first protrusion extending away from the interface surface and having a cavity, and a camera embedded within the cavity and configured to capture video images.

Abstract: A smart trailer system coupled to a trailer of a vehicle includes a sensor configured to measure a parameter of the trailer, a sensor interface board electrically coupled to the sensor and configured to retrieve the measured parameter, and a master controller communicatively coupled to the sensor interface board via a data bus.

Abstract: An electrical harness system for communicatively coupling a first bus node to a bus controller includes a data bus including a first cable segment and a first data line and a second data line, the first and second data lines extending in parallel along a length of the first cable segment and being electrically coupled together at a first end of the data bus, the first bus node being connected to the first data line and not to the second data line, and first and second termination impedances electrically coupled to the first and second data lines at a second end of the data bus.

Abstract: An electrical power monitoring system includes a base at an external surface of a wall of a junction box and including a stem configured to project through an opening in the wall, the base further including a monitoring circuit, a plurality of conductors extending through the stem and coupling the monitoring circuit to a plurality of conductive terminals in the junction box, and a fastener configured to mate with the stem of the base at an internal surface of the wall to fix the base to the wall, wherein the monitoring circuit is configured to monitor presence of electrical power at the plurality of conductive terminals, the monitoring circuit including a plurality of light sources at the external surface of the base.

Abstract: There is provided a charging system configured to charge an auxiliary battery of a vehicle including a tractor, a trailer, and a converter coupled to the auxiliary battery, the charging system including a switch configured to electrically couple an electrical system of the tractor to the auxiliary battery, a diode network configured to receive electrical power from a plurality of auxiliary power sources and to supply power to the converter, and a controller configured to monitor a first input voltage at an input of the switch, a second input voltage at an output of the diode network, and an auxiliary battery voltage, and to control states of the switch and the converter based on the monitored first and second input voltages and the auxiliary battery voltage.
