Abstract: An automated medical test data report, tracking, and patient matching system devised to enable secure transmittal of medical test results data over network between a hosting computing apparatus and at least one receiving computing apparatus is provided. Triple tiered security is enabled by action of paired cryptographic keys, sequencing of data by generation of a randomized and securely-shared sequencing order, and fragmentation of data from a data stream into sortable data packets routable to separate and remotely connected partitions by appending a sort code into each data packet collectively prevent compromise of data in transmission over network.

Abstract: A rotary engine, preferably operating on the 4-event Otto cycle, has a stator ring stationary on a base which also supports a shaft rotational about an axis. The stator ring has oppostie faces normal to the axis. A pair of rotor rings concentric with and mounted on the shaft abut the stator ring side faces. There are cylinders through the stator ring with their axes parallel to the shaft axis. Hollow pistons in the cylinders at their opposite ends bear against cam rings facing and complementary to each other and disposed in the rotor rings. The stator, pistons and cam rings define separate, variable volume chambers to which fuel mixture is supplied through ports in the stator ring and in the piston walls. Ignition devices fire the fuel mixture inside the hollow pistons. Exhaust is through ports in the pistons and stator ring. Lubrication and water cooling connections are provided to and from the stator ring.
