Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for bridging native tokens. Various aspects may include initializing a first blockchain by allocating a plurality of native tokens. Aspects may also include transferring, using a bridge, one or more transactions from a second blockchain to the first blockchain using locked tokens on the second blockchain as collateral. Aspects may also include minting new native tokens at the first blockchain when a value of transactions sum to the plurality of native tokens and the plurality of native tokens are backed by the locked tokens. Aspects may also include reporting, to the second blockchain, the amount of tokens used for the transaction fees in the one or more transactions. Aspects may also include burning, at the second blockchain, tokens corresponding to the amount of tokens used for paying transaction fees.

Abstract: A height adjustable orthosis is described. The orthosis features a belt and a posterior frame. Coupled to the belt, the posterior frame includes a first panel including at least a first fastener and a second rear panel including at least a first lock member and a second locking member. The first panel and the second panel are configured to move vertically relative to each other to position the first fastener to engage at least (1) the first locking member at a first height or (2) the second locking member as a second height.

Abstract: An orthopedic brace features a belt brace and an adjustable spinal support extension. The belt brace includes a structural member. The adjustable spinal support extension is configured for insertion into the structural member. The adjustable spinal support extension includes a sleeve, a first strut member, and a second strut member adjustably coupled to the first strut member to alter a length of the spinal support extension. The first strut member and the second strut member are partially enclosed within the sleeve and a fastener of the structural member is attachable to a fastener on the sleeve when the adjustable spinal support extension is placed within the sleeve.

Abstract: A brace configured to wrap around a lumbar region of a wearer features a first arm and a second arm. Each arm features a first band, a panel slidably disposed at a lateral side of the wearer and coupled to the first band, and a loop connector coupled to the panel on a first end of the panel. The first band has a horizontally extending channel, within which the panel moves. The panel features a rigid material, and the loop connector is tethered to the panel. Moving the connector loop causes moving the panel laterally, which adjusts a location of the panel around the lumbar region of the wearer. The brace may further feature an upper band and a lower band.
