    Abstract: Systems, devices, methods and programs for reducing emissions from engines are provided. For example, one system for reducing emissions from engines comprises a heating controller coupled to an energy storage device (ESD). The heating controller is configured to control a heating element to heat one or more components of an after-treatment system using energy from the ESD under a first condition and to control the heating element to stop heating the one or more components of the after-treatment system when a second condition is satisfied. Additionally, another system for reducing emissions from engines comprises a controller detecting a decrease in a demanded torque from an engine and an ISG. The controller is then configured to operate a clutch to disengage the engine from the ISG, if after removing fuel from the engine, the sensed speed of the engine is above a threshold.

    Abstract: An apparatus for cooling electronic components includes a chassis having a hot side compartment having one or more first electrical components and a cold side compartment having one or more second electrical components. A coolant channel is connected to the cold side compartment. At least one thermoelectric cooler (TEC) is positioned within the cold side compartment. The TEC has a cold plate and a hot plate, the hot plate being connected to the coolant channel and the cold plate being connected to the one or more second electrical components. A method for cooling electronic components using at least one TEC includes identifying an amount of heat to be removed from the one or more second electronic components and determining the TEC with the peak performance based on a best Delta T. The method includes monitoring the Delta T and adjusting the input voltage to maintain the optimum Delta T.

    Abstract: Apparatus and method for authentication components of a public network are disclosed. A master compares an actual HMAC with an expected HMAC, determines that component fails authentication when the actual HMAC does not match the expected HMAC and causes at least one operation to be inhibited when component fails authentication for a preset number of times while the component is connected to the public network. The actual HMAC is determined by the component. The expected HMAC and actual HMAC are independently determined using the same process and using a key. The same key is stored, in advance, in both the master and the component and not transmitted. The master generates a random number and sends the same to the component. The expected HMAC and actual HMAC are determined using the random number input into a one-way hash function.

    Abstract: A battery cell module includes a housing having a stack of a plurality of battery cells. The stack includes a plurality of battery cells sequentially stacked within the housing. Each of the battery cells has first and second opposed faces. The stack further includes a plurality of heat sink plates sequentially interleaved between the plurality of battery cells. Each of the plurality of heat sink plates has a body extending in a first plane surrounded by an outer edge. The body has a plurality of mounting tabs arranged to support a respective battery cell in the sequential stack within the housing such that the plurality of battery cells are maintained in alignment within the housing. A method includes sequentially interleaving battery cells and heat sink plates within a housing, where mounting tabs in the heart sink plates maintain the battery cells in alignment within the housing.

    Abstract: A system for a vehicle is disclosed. The system comprises a gear box. The gear box comprises a first shaft coupled to a first motor and a second shaft coupled to the second motor and a third shift. Each shaft extends through a respective pinion. The gearbox has a first shifter for the first motor and a second shifter for the second motor. The shifters are configured to selectively engage a respective pinion to an appropriate shaft as needed. The gear box further comprises a fourth shaft extending through a first gear and a second gear and an other pinion. The first gear meshes with a first pinion. The second gear meshes with a second pinion. The other pinion meshes with a third pinion and a fourth gear. A differential is mechanically coupled to the fourth gear and a left axle shaft and a right axle shaft.

    Abstract: A hybrid electric vehicle having a controllable switch that enables a DC link to be operated independent from an energy storage system (ESS) is provided. The ESS is selectively couplable to the DC link via the controllable switch. A processor is configured to control the switch to open and close under certain conditions. When the switch is opened, the processor is configured to instruct an engine controller to cause an engine which is coupled to a generator to boost engine output. The generator is coupled to a generator inverter which is also coupled to the DC link. A motor inverter is also coupled to the DC link and is configured to provide AC power to the motor.

    Abstract: Remote electronic units effective to generate output data for an actuator are described. A remote electronic unit may include first, second, and third lanes. The first, second, and third lanes may receive input data including an actuator command. The first, second, and third lanes may generate first, second, and third output data, respectively, based on the input data. The first, second, and third lanes may respectively send the first, second, and third output data to a voter. The first and second lanes may respectively send the first and second output data to a multiplexer. The voter may output a selection signal to the multiplexer if at least two out of the first, second, and third output data are identical. The multiplexer may select one of the first and the second output data based on the selection signal and transmit the selection to the actuator via an actuator control electronics.
