Abstract: Disclosed herein are low dielectric constant (low-k) two-dimensional covalent organic framework materials that have a dielectric constant k less than 2.4, optionally less than 1.9, and are comprised of regularly porous, covalently linked, layer structures.

Abstract: A tire has a carcass reinforcement extending between a pair of opposing bead portion. At least one of the bead portions terminates axially to the outside by a tip and is intended to be mounted on a wheel rim having a bead seat that has an axially outer end closer to the axis of rotation than the axially inner end thereof. Within the bead portion are a bead ring and a bead apex. The radial carcass reinforcement ply is anchored in each bead portion and has at least one terminal end located in the bead portion. In the bead portion, the reinforcement ply passing radially inward of the bead ring, extending axially outward of the bead ring. The reinforcement ply terminates without passing back under the bead ring.

Abstract: A low pressure tire 20 for off road use has a carcass 21 reinforced with carcass plies 22 and a composite structure including a tread 32, a belt or breaker reinforcement 26 and one or more low angle cord reinforced layers 60.

Abstract: A tire initiated vehicle control system 110 for vehicles 100 is described. The vehicles 100 have vehicle components including a power train 140, a suspension system 180, a steering mechanism 160, a plurality of wheel brake mechanisms 130, one wheel brake mechanism 130 being at each wheel position 104a, 104b, 104c, and 104d location, a fuel or vehicle speed throttle 144 with or without a cruise control system, the vehicle control system 110 has a tire pressure detection device 120 and a control means 200, which preferably has a computer 208 for receiving data from the tire pressure detection device 120. The control means 200 processes the received tire pressure data and upon a preset pressure or rate of change value in tire pressure the control means 208 directs a change in response rates of one or more of the above listed vehicle components.
