Abstract: A computing device may determine, based on one or more inputs detected by a presence-sensitive screen, whether at least a threshold amount of liquid is present on the presence-sensitive screen. The computing device may automatically transition the computing device from operating in a first operating mode to operating in a second operating mode responsive to determining that at least the threshold amount of liquid is present. The computing device may discard inputs detected by the presence-sensitive screen while the computing device is operating in the second operating mode.

Abstract: Aspects of the technology relate to temperature regulation for high altitude, long duration balloons, such as balloons that operate in the stratosphere for weeks, months or longer. A balloon covering overlays the balloon envelope, providing an opaque or otherwise light-reflective layer with low emissivity that blocks or reflects optical and/or infrared light. Heat from within the envelope is reflected back from the covering toward the envelope, while light from the sun is reflected back towards the environment. An active venting system is employed to draw in cooler ambient air from the external environment while expelling warmer air from within the envelope. Vent and air intake assemblies of the active venting system are actuated in view of current and/or predicted balloon conditions to regulate internal balloon temperature. This approach reduces repeated pressure changes, which can put undue stress on the balloon envelope and adversely affect the operational lifespan of the system.
