The second seal-forming structure is not configured to contact the at least one stopper rib.

Abstract: A security gateway for touch-free infectious disease screening includes a contactless sensor, a memory and a processor. The contactless sensor is configured to obtain health readings of a subject. The memory stores instructions. The processor executes the instructions. When executed by the processor, the instructions cause the security gateway to measure vital signs based on the health readings of the subject, and determine whether to allow access to a premise based on the vital signs.

Abstract: A patient interface including a positioning and stabilizing structure that is configured to maintain a first seal-forming structure and a second seal-forming structure in a therapeutically effective position. The positioning and stabilizing structure comprises a frame coupled to the plenum chamber. The frame includes a central portion coupled to the plenum chamber outside of the cavity. The frame also includes a pair of arms that extend away from the central portion in a posterior direction past the second seal-forming structure. The pair of arms are more flexible than the central portion. The positioning and stabilizing structure also includes headgear straps coupled to the frame, which configured to provide a tensile force to the first seal-forming structure and to the second seal-forming structure into the patient's face via the frame.

Abstract: A hybrid display may include different display portions with different resolutions. The high resolution display portion may be positioned in a main viewing area for the viewer whereas the low resolution display portion may be positioned in a peripheral viewing area. The high resolution display portion may have a silicon backplane. The low resolution display portion may have a different type of backplane such as a thin-film transistor backplane. The different display portions may optionally share a common organic light-emitting diode layer such that light is emitted from the same plane across both display portions. The high resolution display portion may emit light through a transparent window in the low resolution display portion. A high resolution display may also be formed by separately forming a frontplane and a backplane. Conductive attachment structures such as indium bumps may be used to mechanically and electrically connect the backplane to the frontplane.

Abstract: In this disclosure, a method for the update of a distributed ledger of a cryptocurrency is presented whereby transaction data need only be broadcasted once in the cryptocurrency network, thereby reducing the bandwidth consumption of the consensus nodes in the network. This is achieved with a two-stage process where in the first stage, a consensus is reached on the transactions that were received from every consensus node in the network. In the second stage, each consensus node uses an identical predefined protocol to obtain a subset of transactions from the total set reached in the first stage, with the predefined protocol being any systematic and deterministic way of obtaining the subset of transactions that are valid such that no cryptocurrency address is overdrawn. A consensus is then reached by the network on the state of the updated ledger after inclusion of this subset of transactions in the distributed ledger.

Abstract: In this disclosure, a method for the system of operation of a decentralized staking pool within a proof-of-stake cryptocurrency framework is presented. Stakeholders of a staking pool do not send their stakes to the staking pool. Instead, their association with the staking pool is validated and recorded by other nodes in the cryptocurrency network. Stakeholders who cannot afford expensive computing infrastructure may still participate via the staking pool in a high-throughput and dense network capable of processing tens of thousands of transactions per second with fast transaction confirmation times not limited by long message relay times over a broad and sparse network. After a staking pool has been accepted into the network, it may start validating transactions and participating in the consensus of the distributed ledger, with regular updates of its list of stakeholders to the network, as well as the crediting of transaction fees to its stakeholders.
