Abstract: Provided herein is an electrophoresis separation medium comprising: (a) a non-crosslinked or sparsely cross-linked polymer or copolymer; (b) one or more denaturant compounds, in an amount sufficient to inhibit re-naturation of single stranded polynucleotides; (c) an aqueous solvent; (d) optionally, a wall-coating material suited to inhibition of electroosmotic flow; and (e) optionally, an organic water miscible solvent such as DMSO or acetonitrile, wherein the electrophoresis separation medium exhibits functional stability for at least seven days at 23° C. Also provided herein are sieving compositions, including polymer-based sieving compositions, for molecular sieving as well as related kits, devices and methods of use. Such compositions can be useful for separation of biomolecules such as nucleic acids, proteins, glycoproteins and glycans.

Abstract: A charging station for an electric vehicle determines that a first person is in proximity to the charging station and identifies whether the first person is a user of the charging station. In accordance with a determination that the first person is a user of the charging station, the charging station provides, using a first mode for selecting content for users of the charging station, first content for display. The charging station determines that a second person is in proximity to the charging station and identifies whether the second person is a user of the charging station. In accordance with the determination that the second person is not a user of the charging station, the charging station provides, using a second mode for selecting content distinct from the first mode for selecting content, second content for display. The second mode provides content for non-users of the charging station.

Abstract: An approach is provided for estimating electric vehicle (EV) charging station demand at specifics points of interest. A method includes determining a percentage of visitors to a point of interest (POI) that are electric vehicle (EV) drivers, a first percentage of the EV drivers qualifying as essential drivers, a second percentage of the EV drivers qualifying as opportunistic drivers. The method includes feeding input data to an inference engine, wherein the input data includes the above percentages, a number of visitors to the POI, and charge rates for the opportunistic and essential drivers. The inference engine generates output data regarding predicted EV charging demand for the POI, and generates a display based on the output data.

Abstract: An approach is provided for estimating the optimal number and mixture of types of electric vehicle (EV) charging stations (EVCS) at one or more points of interest (POIs). A method includes generating, based on an EV adoption model, an EV adoption prediction. The method includes generating, based on a mobility simulation model, a driver-type prediction that predicts percentages of EV drivers qualifying for various EV driver types. The method includes generating, based on the EV adoption prediction, the driver-type prediction, and a visitation model, a visitation prediction that predicts how many EV drivers of each type of EV driver will visit the POI. The method includes determining and displaying, based on how many EV drivers of each type of EV driver is predicted to visit the POI, for each type of EV charging station of a plurality of types of EV charging stations, an optimal number of EVCS to install.

Abstract: The disclosed embodiments include a charging station for an electric vehicle. The charging station includes a plurality of light sources, one or more processors, and memory storing instructions for performing a set of operations. The set of operations includes determining a state of the charging station, the state indicating a status of an electric vehicle at the charging station. In accordance with a determination that the state is a first state, the charging station provides a first visual indication of the first state using a first light source of the plurality of light sources. In accordance with a determination that the state is a second state, the charging station provides a second visual indication of the second state.

Abstract: An electric vehicle (EV) charging station includes a frame and a panel having an interior surface and an exterior surface. The panel is hinged to the frame so as to articulate the panel away from the frame. The panel includes a display facing outwardly from the exterior surface of the panel and mounted on the interior surface of the panel. The EV charging station further includes a computer accessible when the panel is articulated away from the frame, the computer including one or more processors and memory, the memory storing instructions for displaying content on the display.

Abstract: Systems and methods are described which provide targeted advertisements to a charging station for electric vehicles. A data collector records data associated with individuals near a charging station. A meter determines whether the charging station is being used to charge an electric vehicle. When the charging station is being used, a display displays advertisements targeted to the individuals. The targeted advertisements are selected from a database according to the data recorded by the data collector, and the database stores advertising content with discrete advertising segments that are electronically accessible. A processor is coupled to the data collector, the meter, and the display. The processor transmits the data recorded by the data collector, and receives the targeted advertisements.
