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: Rapidly water-disintegrable tablet is provided comprising an active ingredient such as a foodstuff or medicament, and distributed therewithin a small but effective amount of a tablet disintegrable system comprising an unreacted, intimate mixture of alginic acid and a water soluble metal carbonate in proportions reactive to form metal alginic acid salt and carbonic acid when the tablet is placed in water, the bulk of the salt acting to swell the tablet and the carbonic acid acting to simultaneously release carbon dioxide within the swelling tablet whereby rapid disintegration of the tablet is effected.
