Abstract: A modular battery system for an electric vehicle is disclosed. The modular battery system includes a base battery module installed in a motor vehicle at a designated battery tray location and a second battery module installed in said motor vehicle at a second location remote from the designated battery tray location. The base battery module and the second battery module share a single battery cooling system.

Abstract: Aspects of the subject technology provide for transcription of audio content during a conferencing session, such as an audio conferencing session or a video conferencing session. The transcription can be generated by the device at which the audio input is received, and transmitted to a remote device at which the transcription is displayed. Video content can also be provided from the device that generates the transcription to the remote device that displays in the transcription. The transcription can be provided with time information corresponding to time information in the video content, for synchronized display of the transcription and the corresponding video content.

Abstract: A method and system for employing thermoelectric generators for capturing otherwise lost thermal energy associated with operation of an electric vehicle.

Abstract: A highly efficient heating system for an electric motor vehicle embodies a heat exchanger for warming passenger compartment air and an electrically powered radiant heating source for heating fluid to be circulated through the heat exchanger. The radiant heating source can be infrared, microwave or other frequency selected to efficiently heat the fluid to be circulated through the heat exchanger.

Abstract: A weather update system, method, and device for providing and receiving weather data. The mobile computing device includes a processor and a location data receiver capable of establishing a geospatial location of the mobile computing device based on received data signals. The mobile computing device is configured to receive updated weather data in response to a threshold condition having been, met, such as a threshold distance having been traveled by the mobile computing device or a threshold time having elapsed. The mobile computing device is also configured to receive weather alerts. The system includes a weather data server network configured to receive current and forecasted weather data for a plurality of locations and times, stored in a high-resolution grid structure and including current locations of a user devices or favorite locations for users.
