Abstract: Aerial vehicles may be equipped with propellers having pivotable blades that are configured to rotate or fold when the propellers are not rotating under power. A pivotable blade may rotate about an axis of a propeller with respect to a hub in the presence of wind flow until the pivotable blade is coaligned with a fixed blade, in a direction opposite to the wind flow. A pivotable blade may also fold over a hub of a propeller in the presence of wind flow, with the pivotable blade and a fixed blade being oriented in directions opposite to the wind flow. A center of mass of the pivotable blade may be caused to be on the same side of an axis as a center of mass of a fixed blade, even where the axis is not normal to the wind flow, thereby reducing an amount of drag generated by the propeller.

Abstract: An electronic device includes an elongated tubular housing. One or more electronic components are coupled to a chassis disposed in a cavity of the tubular housing. A pair of elongated channels are positioned on opposite sides of the chassis and between the chassis and a sidewall of the tubular housing. The channels are tapered or wedge-shaped along their lengths. During assembly, one of the channels may be slid longitudinally along the other, causing the channels to expand laterally, due to their wedge shape, to secure the chassis in the tubular housing. The chassis and the pair of channels provide a thermally conductive path to dissipate heat. During use, heat generated by the electronic components is transmitted radially outward from the electronic components, through the chassis and the pair of channels, and through the tubular housing to the exterior of the portable electronic device.

Abstract: Each of one or more temperature sensors of a computing system can measure and provide a temperature value (e.g., provide temperature data) to the system. In some embodiments, the system can apply an offset value, a time-based filter, and a weighting factor to each temperature value received from the one or more temperature sensors of the system. Based, at least in part, on the offsetting, filtering, and/or weighting, the computing system can determine (e.g., calculate, estimate, predict, etc.,) a temperature value representative of an enclosure temperature of the system. In some embodiments, based on the determined temperature value that is representative of the enclosure temperature, the computing system can perform appropriate subsequent processing in accordance with thermal management of the system.

Abstract: A computing device and method including a thermal sensor positioned on a flexible circuit located in close proximity to the device enclosure or hot-spot to most accurately track and control skin temperature of the electronic device. One or more flexible circuits may be implemented to include one or more low profile temperature sensors specifically located to detect temperature in close proximity to the enclosure and/or components of interest or hot spots which may be more accurately monitored by locating the low profile temperature sensor on the flexible circuit within the enclosure without substantially increasing the z-height of the existing flexible circuits or taking up additional room within the enclosure.
