Abstract: A battery cell chemistry test fixture includes a housing including a battery cell chamber. A first electric terminal is electrically connectable to a battery cell in the battery cell chamber. A second electric terminal is electrically connectable to the battery cell in the battery cell chamber. A plurality of sensor connectors is mounted to the housing. The plurality of sensor connectors include at least a gas sampling connector, a pressure sensor connector, and a valve connector, each of the gas sampling connector, the pressure sensor connector, and the valve connector being fluidically connected with the battery cell chamber.

Abstract: A smart trailer coupler system includes a ball mount connectable to a vehicle, a hitch ball mechanically connected to the ball mount, a coupler selectively connectable to the hitch ball, and at least one sensor mounted to one of the ball mount, the hitch ball and the coupler. The at least one sensor detects a size compatibility between the coupler and the hitch ball. A signal system is operatively connected to the at least one sensor. The signal system provides at least one of a visual alert and an audible alert of the size compatibility between the hitch ball and the coupler.

Abstract: A method for monitoring and diagnosing an engine exhaust treatment of an internal combustion engine in a motor vehicle includes monitoring a nitrogen oxides (NOx) storage catalyst disposed in an engine exhaust stream downstream of the engine, determining a first diagnostic condition of the NOx storage catalyst based on data from a first EGT sensor and a second EGT sensor; determining a second diagnostic condition of the NOx storage catalyst based on a comparison of temperatures reported by a first NOx sensor and a second NOx sensor, selectively pausing the first diagnostic condition and the second diagnostic condition during a predetermined NOx storage catalyst regeneration period, and selectively generating a notification for an operator of the motor vehicle.

Abstract: Systems and methods are provided for heat management using vascular channels. Vascular channels are incorporated in a network within a component. The component is a part of a manufactured product and defines an exterior panel. A fluid circuit is connected with the vascular channels and circulates a fluid through the component to collect heat from the product and to dissipate heat through the exterior panel.

Abstract: A vehicle includes a NOx storage converter to receive exhaust gases from a diesel engine, store at least a minimum amount of the NOx at a temperature below a storage threshold, release the NOx at a temperature above a releasing threshold, oxidize hydrocarbon, and oxidize carbon monoxide. An input temperature sensor at an entrance to the NOx storage converter determines an input temperature of the exhaust gases. An output temperature sensor is at an output of the NOx storage converter to determine an output temperature of the exhaust gases. A control module receives the input temperature and the output temperature, determines a magnitude of an exotherm in the NOx storage converter, and stores an electronic fault code in a computer memory in response to the magnitude of the exotherm being below a minimum temperature. The fault code indicates a reduction in a NOx storage capacity of the NOx storage converter.

Abstract: A method for diagnosing an Oxidation Catalyst (OC) device of an exhaust gas treatment system is provided. The method monitors a differential temperature across the OC device. The method determines whether the differential temperature reveals a temperature spike. The method determines that the OC device operates properly in response to determining that the differential temperature reveals a temperature spike.
