Abstract: Presented are vehicle control systems and logic for monitoring device batteries to provision virtual key functionality, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a vehicle includes wire or wirelessly connecting a remote keyless entry (RKE) system with a wireless-enabled portable electronic device (PED) of a user. A vehicle controller receives a unique virtual key code from the user's PED to enable use of the RKE system and, after receiving the virtual key code, determines a battery charge level of the PED's battery. The vehicle controller then determines if the battery charge level is less than a preset minimum charge level and if the vehicle powertrain is off. If the powertrain is off and the battery charge level is less than the minimum charge level, the controller responsively commands a resident vehicle subsystem to execute a control operation for charging the PED battery.

Abstract: A method for forming an electroactive material includes sourcing a current or voltage to an electrochemical reactor that includes a cation source, an electrolyte mixture, and an electroactive material precursor in contact with one another, where the current or voltage serves to ionize and form cations at the cation source that react with the electroactive material precursor in the electrolyte mixture to form the electroactive material. The method may include one or more filtering steps, one or more rinsing steps, or a combination of one or more filtering steps and one or more rinsing steps to collect the electroactive material from the electrolyte.

Abstract: A method of automatic selection of an operating mode of a motor vehicle feature includes receiving, via an electronic controller, an input signal communicated by an input device, including at least one of a geographical and a temporal condition for operation of the motor vehicle feature. The method also includes setting, via the electronic controller, at least one of the geographical and the temporal condition for operation of the motor vehicle feature. The method additionally includes determining, via the electronic controller, a current geographical location of the motor vehicle and/or a current time. The method also includes comparing, via the electronic controller, the current geographical location and/or the current time with the corresponding set condition. Furthermore, the method includes selecting, via the electronic controller, the operating mode of the motor vehicle feature when the current geographical location and/or the current time matches the corresponding set condition.

Abstract: A press-in-place seal for an interface between adjacent components, with the seal including a cylindrical structure arranged along a longitudinal axis and characterized by a J-shape in a cross-sectional view. The seal is arranged inside a first component and compressed by a second component when the PIP seal is installed within the interface. The J-shape includes a first stem section orthogonal to and extending toward the longitudinal axis for being compressed by the second component when the seal is installed within the interface. The J-shape also includes a second stem section longer than the first stem section, orthogonal to and extending toward the longitudinal axis, for stabilizing the structure when the seal is installed. The J-shape further includes a base third section arranged parallel to the longitudinal axis and connecting the first stem section to the second stem section, thereby defining a concavity between the first and second sections.
