Abstract: A docking system for an AV may include a connector coupled to an electronics housing of a docking station and configured to operably engage an AV to couple the AV to the electronics housing, a processor coupled to the connector and configured to enable fast-charging of the AV through the connector, a processor coupled to the connector and configured to transfer data to and receive data from the AV through the connector, and a processor of the AV configured to automatically align the AV with the connector. The docking system may further include a weather enclosure to house an AV while the AV is docked.

Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

Abstract: A heating module for an oxygen sensor comprises an estimated mass module, a cumulative mass module, and a temperature control module. The estimated mass module determines an estimated mass of intake air to remove condensation from an exhaust system after startup of an engine. The cumulative mass module determines a cumulative mass of intake air after the engine startup. The temperature control module adjusts a temperature of an oxygen sensor measuring oxygen in the exhaust system to a first predetermined temperature after the engine startup and adjusts the temperature to a second predetermined temperature when the cumulative air mass is greater than the estimated air mass, wherein the second predetermined temperature is greater than the first predetermined temperature.

Abstract: A diagnostic system for an exhaust system including a catalyst and a post-catalyst oxygen sensor is provided. The system generally includes a fuel control module that commands fuel to transition from a rich condition to a lean condition and that commands fuel to transition from the lean condition to the rich condition. A first diagnostic module monitors the post-catalyst oxygen sensor during the transition from the rich condition to the lean condition. A second diagnostic module monitors the catalyst during the transition from the lean condition to the rich condition.

Abstract: A control system for an oxygen sensor heater is provided. The control system includes a passive heater control module that generates a heater control signal at a first duty cycle and measures a resistance of the oxygen sensor heater. An exhaust gas temperature mapping module maps the resistance to an exhaust gas temperature. An active heater control module generates a heater control signal at a second duty cycle based on the exhaust gas temperature.

Abstract: An engine exhaust sensor diagnostic system for an exhaust system including a catalyst and a post-catalyst oxygen sensor includes a first module that calculates a total integrated area based on a signal generated by the post-catalyst oxygen sensor. A second module compares the total integrated area to a threshold integrated area and generates a pass status signal when the total integrated area is less than the threshold integrated area.
