Abstract: An occupant support for a vehicle includes a vehicle seat and a foundation. The vehicle seat is configured to support an occupant of the vehicle above a floor of the vehicle. The foundation is configured to interconnect the vehicle seat to the floor to permit movement of the vehicle seat relative to the floor along a linear path.

Abstract: Systems and methods for micro-transactions using virtual currency via a blockchain. A central authority server provides a shadow ledger to track verified but unposted transactions with respect to users of the virtual currency economy. New proposed transactions are checked against both the master records in the blockchain database and the shadow ledger to confirm that, when posted to the blockchain, they will be valid. Confirmed transactions are authenticated via tokens provided to users, who then remit the tokens to participants in exchange for access to content (e.g., paywall content, ad-free content, etc.). Users may acquire virtual currency through similar micro-transactions conducted in reverse. The unposted, cached transactions are then posted to the blockchain in bulk.

Abstract: Systems, method, and apparatus for locking a movable component of a tool into an operationally static position. A locking mechanism embedded within an interior cavity of a tool is operationally connected to a squeeze handle via a linkage assembly. When the handle is squeezed, the linked assembly drives the locking mechanism toward the movable component. Corresponding gear racks on the locking element and movable element inhibit movement in both vectors, using a zero degree pressure angle to strongly inhibit movement in another factor, and using a non-zero degree pressure angle to less firmly inhibit movement in an opposing vector.
