Abstract:

A robust device messaging framework is disclosed that enables a user to send commands to a device. A provisioning service is used to provision unique device identities and maps user web identities to device identities. The provisioning service also limits device per day provisioning attempts to limit denial of service attacks. A command service allows remote users to issue commands to a device, synchronize outgoing commands with incoming results, receive accurate feedback about whether a command was received, and maintain state information about the device. A device layer encrypts and stores device identities, authenticates itself with the command service, establishes a high-availability Internet connection to receive alerts that a command has issued, and reports results to the server-based command service.

Abstract:

A low cost, disposable temperature sensor comprising a non-porous rigid substrate having a colored patch of a contrasting color, covered by a thermochromic material which obscures the colored patch. The thermochromic material, which has a color in the visual range which completely obscures the underlying colored patch, is selected to have a melting or solidus point such that when the material is exposed to a predetermined temperature, the thermochromic material permanently changes to a relatively transparent color whereby the colored patch on the substrate is rendered visible through the thermochromic material. A transparent cover or film encapsulates the thermochromic material place on the substrate. In a preferred embodiment of the invention, the substrate comprises a paperboard product, and includes printed indicia for making a permanent record. The sensor has particular utility in measuring safe cooking temperature of food,.
