Abstract: A thermal storage system includes a container, a thermal exchange device, a first thermal storage material, and a second thermal storage material. The first thermal exchange device is disposed in the container. The first thermal storage material is disposed in the container and is spaced apart from the thermal exchange device. The second thermal storage material is also disposed in the container in contact with the thermal exchange device. The first and second thermal storage materials are immiscible. The second thermal storage material is less reactive with the construction material of the thermal exchange device as compared to the first thermal storage material. Optionally, a second thermal exchange device can be submerged in the second thermal storage material. The first thermal exchange device is configured to supply heat to the second thermal storage material and the second thermal exchange device facilitates extraction of heat from the second thermal storage material.

Abstract: A method of operating a vehicle climate system when an ambient temperature is below a threshold temperature is provided. In response to an ambient temperature being less than a threshold temperature, a controller is adapted to operate a blower motor at a voltage that depends on whether the vehicle is in charge sustain mode or charge deplete mode. In response to an ambient temperature being greater than a threshold temperature, the controller is adapted to operate the blower motor at a voltage that does not depend on whether in the charge sustain or charge deplete modes.

Abstract: A vehicle climate system includes a blower and a controller. The controller is configured to, responsive to input of a particular user selected climate setting, operate the blower with an initial power having a predetermined value corresponding to the climate setting provided that cabin temperature is outside a predetermined range. The controller is also configured to operate the blower with an initial power having a value less than the predetermined value provided that the cabin temperature is within the predetermined range.

Abstract: A method, apparatus, system, and computer program products for managing a set of outliers in test data. A computer system analyzes a set of features derived from the test data using different outlier detection methods to generate a result of the set of outliers identified by the different outlier detection methods. The test data is obtained from testing a physical structure. The computer system determines a causality for the set of outliers in the result. The physical structure is retested with a set of changes determined using the causality identified for the set of outliers. The retesting generates new test data for the physical structure.

Abstract: A method, apparatus, system, and computer program product for managing a physics simulation model. A machine learning model is trained to output predicted test results for sets of simulation values for a set of simulation parameters using a training data set based on test results for physical structures to form a surrogate model. Current simulation values for simulation parameters are selected using the surrogate model and a cost function. Simulation test results are generated using the physics simulation model that implements the current simulation values selected for the simulation parameters. The simulation test results are compared with physical test results from testing the set of physical structures using physical test inputs applied to the physical structures to form a comparison. The surrogate model is trained using the current simulation values selected for the simulation parameters using the surrogate model in response to the comparison being outside of a tolerance.

Abstract: A method of operating a vehicle climate system when an ambient temperature is below a threshold temperature is provided. In response to an ambient temperature being less than a threshold temperature, a controller is adapted to operate a blower motor at a voltage that depends on whether the vehicle is in charge sustain mode or charge deplete mode. The controller operates the blower motor according to a first voltage responsive to a charge sustain mode, and operates the blower motor according to a second voltage different than the first voltage in response to a charge deplete mode.

Abstract: A simulated flame and wick device for use with a flameless candle and other devices requiring the appearance of a natural flame. A flame shaped housing, comprising an upper and lower cover, contains a flexible LED filament bulb, with the positive and negative leads passing through dedicated channels within a housing designed to have the appearance of a candle wick. The combination of the material used for the wick housing along with the positive and negative leads from the flexible LED filament bulb are designed to provide strength and flexibility to the wick component. In turn these leads pass through a positioning housing to orient the simulated flame and wick correctly when used with flameless candles and other devices. The simulated flame and wick along with the other components described are contained within the internal housing of a simulated candle shell or other appropriate device, thus simulating the appearance of a flame burning atop a blackened wick.
