Abstract: The method for synthesizing graphene derivatives from asphaltene includes one or more steps that are based on thermal and/or chemical treatments. In the thermal treatment, asphaltene was carbonized in a rotating quartz-tube furnace under an inert atmosphere (N2). This carbonization process was performed at a temperature range of 400-950° C. The carbonization process converted asphaltene molecules into graphene derivatives by eliminating the alkyl side chains, exfoliating the aromatic layers (n), and expanding the aromatic sheet diameter (La). The chemical treatment, on the other hand, was performed on the asphaltene (i.e., graphene precursor) by dispersing the asphaltene molecules in a liquid intercalating agent to functionalize the asphaltene and expand the inter-layer distance between the aromatic sheets (intercalation). In this intercalation process, the graphitic surface of asphaltene is oxidized to form asphaltene oxide, and then graphene oxide (GO), which is a nonconductive hydrophilic carbon material.

Abstract: Methods and a system are described for prioritizing the upload of connected vehicle map data in a central mapping system. A central mapping unit includes a central server which receives and processes data uploads by priority order, from highest priority to lowest priority. The uploaded data is compared to central map data to determine whether the central map requires updating. When the central mapping unit determines that there is not enough information to update the central map in a region, a priority list is updated to give high priority to data collection in the region. The updated priority list is pushed to connected vehicles travelling in the region, which have external sensors for data collection in the surrounding environment. When a connected vehicle enters the region, its external sensors collect data regarding the region, which is uploaded to the central mapping unit with highest priority.

Abstract: Systems and methods of controlling a clutch in a vehicle are provided. With the goal of enabling autonomous/assisted control of the clutch by an electronic control unit while preserving the familiar mechanical feeling at the clutch pedal that driving enthusiasts prefer, embodiments of the disclosed technology use a shuttle valve to blend control of clutch engagement between a driver and an ECU. In these embodiments, a clutch pedal in the vehicle may be mechanically connected to a piston in a first hydraulic cylinder (just like in a traditional mechanical/hydraulic clutch actuation system), and an ECU may actuate a second hydraulic cylinder. Accordingly, a shuttle valve may be used to route the fluid coming from the cylinder with the greater pressure (i.e. the driver actuated cylinder or the ECU actuated cylinder), to a third hydraulic cylinder which adjusts engagement of a clutch by a mechanical linkage.

Abstract: A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.
