Abstract: An Internet of Things (IoT) device is deployed with embedded software that may comprise multiple components. After deployment, updated versions of one or more components of the embedded software may become available. The IoT device maintains a manifest of the installed components. Periodically, the IoT device requests an updated copy of the manifest from an upgrade server. The installed manifest and the updated manifest are compared to determine if updated versions of any components are available. If so, the IoT device requests only the components to be updated. Prior to beginning the copying of the upgraded components, an upgrade flag is set. The IoT device then begins copying the received components into memory, replaces the manifest with the updated manifest, and clears the upgrade flag.

Abstract: The invention relates to a solar plant (1) having at least one pivotable module table (2a, 2b, 2c) which supports at least one photovoltaic solar module (3), preferably multiple photovoltaic solar modules (3), and is coupled in such a manner to at least one gear element (4) pivotable about an axis (A) that pivoting the gear element (4) causes the module table (2a to 2c) to be pivoted so that the solar modules (3) track the motion of the sun, the gear element (4) being driven and thus pivoted by an electrically driven drive shaft (5), at least one actuation element (8) being integrated in the drive shaft (5), the gear element (4) being both driven and blocked by the actuation element (8), the actuation element (8) engaging into the toothing (11) of the gear element (4) for driving or blocking the gear element (4).
