  • Patent number: 11908257
    Abstract: User access to a physical location (e.g., a homes, businesses, or other locations) may be granted for certain limited tasks based on one or more access procedures stored in a registry and associated with an identity of the user. Such access may be given without including an interaction with an owner, administrator, or manager of the location. User individuals may self-identify themselves to an access server or registry after arriving at the premises and receive corresponding access privileges via one or more devices within the premises based on access procedures stored in the access registry. The access procedures may be executed by the access server through communications with access devices within or about the premises and may be tailored based on the type of user individual or type of access requested.

  • Publication number: 20230243602
    Abstract: A heating and/or cooling temperature adjusting apparatus disposed proximate a point of use comprising a heat exchange structure, at least one thermal mass unit comprised of a material which changes phase at a predetermined temperature, and a housing which at least partially encloses the heat exchange structure and thermal mass unit. Additionally, a plurality of thermal mass units can be employed, each with equivalent, or differing, temperature threshold points for conversion between solid, liquid or gaseous phases. The presence of the thermal mass unit at the point of use allows for the heating/cooling system to rapidly adjust the temperature of the room while simultaneously decreasing the duty cycle of the heating/cooling generator (e.g. boiler).
