One example method generally includes selecting a first output of a plurality of outputs of the SMPS based on a power demand associated with each of the plurality of outputs if a voltage at the first output is less than a reference voltage associated with the first output, by selecting as the first output one of the plurality of outputs having the highest power demand, and based on an amount of overcharge associated with the first output if the voltage at the first output is greater than the reference voltage, by selecting as the first output one of the plurality of outputs having the lowest amount of overcharge. The method may also include directing current across an inductive element of the SMPS to the first output based on the selection.

Abstract: Camera calibration may be performed in a mobile environment. One or more cameras can be mounted on a mobile vehicle, such as an unmanned aerial vehicle (UAV) or an automobile. Because of the mobility of the vehicle the one or more cameras may be subjected to inaccuracy in imagery caused by various factors, such as environmental factors (e.g., airflow, wind, etc.), impact by other objects (e.g., debris, vehicles, etc.), vehicle vibrations, and the like. To reduce the inaccuracy in imagery, the mobile vehicle can include a mobile camera calibration system configured to calibrate the one or more cameras while the mobile vehicle is traveling along a path. The mobile camera calibration system can cause the one or more cameras to capture an image of an imaging target while moving, and calibrate the one or more cameras based on a comparison between the image and imaging target data.

Abstract: Systems and corresponding methods for monitoring of a state of charge or a state of health of a battery are described. For example, the battery monitoring system may include strain gauges to measure dimensions or changes in dimension of cells of the battery, and may determine states of charge of the cells based on dimensional changes over time, e.g., based on data from strain gauges. The dimensional changes may also be corrected for dimensional changes due to thermal strain. In addition, states of health of individual cells of the battery may be determined by comparing the dimensional changes of each of the cells over time. Further, the data from strain gauges may be received at various frequencies, e.g., based on an expected operational duration of the battery and/or based on a current state of charge or state of health.

Abstract: Described is an imaging component that utilizes two rolling shutter sensors for motion detection of objects and for depth mapping of objects within an effective field of view of the imaging component. Unlike traditional stereo cameras that utilize global shutter sensors to avoid distortions, or attempting to remove distortions created by rolling shutter sensors, the disclosed implementations emphasize the distortions created by rolling shutters imaging moving objects and utilize that information to determine that the objects are moving and/or to determine a range or distance of the object from the imaging component. For example, a first rolling shutter sensor is oriented in a first orientation such that the scanlines generate the image from a top of the sensor to the bottom of the sensor, and a second rolling shutter sensor is oriented in a second orientation such that the scanlines generate the image from a bottom of the sensor to the top of the sensor.

The rows may be arranged along the linking member in a repeating sequence of the multiple pitch lengths.

Abstract: A disturbance cancellation and generation seat system includes a seat mounted to a structure of a vehicle. The seat is accelerated due to a disturbance acceleration received in the structure and transferred to the seat. A seat control unit generates a force cancellation command signal. An actuation device is connected to the structure and is in communication with the seat control unit. The actuation device in response to receipt of the force cancellation command signal induces a cancellation acceleration motion into the seat which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.
