Abstract: A height-adjustable seat, which may be used for meditation, is provided that is height adjustable to position a user closer to a floor as the user gains flexibility and position the user further from the floor in case of injury. The height-adjustable seat includes a pivotal frame having a first upper cross bar and a spaced apart second upper cross bar. A sling seat is suspended between the cross bars and is adjustable in width to raise and lower the height of the sling seat relative to the floor. The sling seat includes a free, first end and a fixed, second end. The second end is connected to the second upper cross bar of the frame and the first end is releasably engageable with a lower surface or side of the sling seat.

Abstract: The present disclosure presents blockchain-based cyber security management systems and related methods. One such method comprises obtaining cyber intelligence input data from a cyber defender computing device, wherein the cyber defender computing device manages network security of a network, wherein the cyber intelligence input data identifies a cyber attacker or a victim of a cyber attack on the network; executing one or more Cyber Security Management (CSM) functions with the cyber intelligence input data received from the cyber defender computing device and cyber data stored in the blockchain ledger, wherein the cyber data stored in the blockchain ledger provides details on a cyber attack on a network that is managed by another cyber defender computing device; and outputting an alert to the cyber defender computing device with a potential cyber attacker or potential victim of the cyber attack on the network managed by the cyber defender computing device.

Abstract: A cross-domain solution architecture includes a higher-security domain and a lower-security domain. The higher-security domain (i) processes data on a higher-security level, and (ii) includes a hardware-based trusted executed environment (TEE) running a formally verified microkernel. The lower-security domain (i) processes data on a lower-security level having lower security than the higher-security level, and (ii) includes a trusted computer base (TCB). The TCB operates in the higher-security domain and the lower-security domain to pass data from the lower-security domain to the higher-security domain through a first data diode, and to pass data from the higher-security domain to the lower-security domain through a second data diode.
