Abstract: A mobile locker includes one or more dispensing units. Each dispensing unit consists of an accessible product space where each product space also includes a temperature monitor. A passible environmental control incudes a multiple of containers located around the perimeter of each accessible product space. Further, each of the containers incorporates a phase change material (PCM) that is used to temperature condition each accessible product space.
Abstract: The concepts include a user support system in the form of a microphone, a visual display arranged in a vehicle cabin, and a controller. The controller includes an instruction set that is executable to receive, via the microphone, a voice-based request from a user, and employ a virtual assistant to determine a user interaction in real time and to determine a specific intent for the voice-based request, including capturing metadata. A user interaction routine determines a user interaction parameter associated with the virtual assistant based upon the voice-based request from the user. A user sentiment analysis routine determines a user satisfaction parameter associated with the virtual assistant based upon the voice-based request from the user. The controller responds in real-time to the voice-based request based upon the user satisfaction parameter and the user interaction parameter that are associated with the virtual assistant.
