A new block on a lower frequency ring chain stores an aggregation of data from the blocks that were added to a higher frequency ring chain in the time since the previous addition of a block to the lower frequency ring chain. Thus, a system of ring chains stores progressively summarized state transition data over progressively longer time intervals while maintaining immutability of the record and reducing storage requirements.

The receiver may be configured to adjust a mode of the modal antenna based on the control signal transmitted by the transmitter.
US11742565B2	Semiconductor devices and methods of manufacturing semiconductor devices A semiconductor device can comprise a substrate dielectric structure and a substrate conductive structure that traverses the substrate dielectric structure and comprises first and second substrate terminals; an electronic component with a component terminal coupled to the first substrate terminal; and a first antenna element with a first element terminal coupled to the second substrate terminal, a first element head side adjacent a first antenna pattern, a first element base side opposite the first element side, and a first element sidewall. The first element terminal can be exposed from the first element dielectric structure at the first element base side or at the first element sidewall. The first antenna pattern can be coupled to the substrate through the first element terminal. The substrate conductive structure can couple the first antenna element to the electronic component. Other examples and methods are also disclosed.
US11742563B2	Backdoor and rear glass A backdoor includes a resin outer panel having an opening; a resin inner panel; a metal reinforcement arranged between the outer panel and the inner panel; and a rear glass covering the opening. The rear glass includes a defogger, and an antenna conductor capable of receiving radio waves in an AM band. The antenna conductor includes a power feeding part, and an antenna element having a predetermined length and connected to the power feeding part. The antenna element includes a proximity part extending along an outer edge among upper, lower, left, and right outer edges of the defogger, and having a predetermined spacing from the outer edge. The antenna element is positioned to be separated from the reinforcement by a predetermined spacing, or positioned on a side with respect to the outer edge where the reinforcement is not present in plan view of the rear glass.
US11742562B2	Deployable antenna system A deployable antenna system for deployment in an extraterrestrial environment is provided, the deployable antenna system comprising a deployment mechanism including one or more extendable support structures comprising at least one axial support structure adapted to extend in a z-direction parallel to a z-axis in the deployable antenna system and a deployable antenna attached to the one or more extendable support structures and adapted to be stowed in an undeployed state and to be unfurled into a deployed state by the deployment mechanism, the deployable antenna being further adapted to extend and unfurl during deployment from the deployment mechanism in the z-direction responsive to extension of the at least one axial support structure, the deployable antenna including one or more flexible membranes coupled to the at least one axial support structure and extending from the z-axis in the deployed state.
