Abstract: A system for visual encoding of words to assist learning to read including systematic variations in the appearance of letters which may look like morphic analogs of the sound variations they suggest (for example, barely visible grey for silent letters). By improving how letters cue sounds (like the alphabet originally did), visual encoding reduces the cognitive processing work that most impedes and endangers the progress of beginning and struggling readers (disambiguating letter-sound relationship confusion).

Abstract: A cryogenic and thermal source cogeneration method for converting energy from a heat source, through a cryogenic heat transfer process, into mechanical and/or electrical energy, comprising, utilizing a vapor compression cycle (2) to absorb heat from the heat source and, utilizing a Rankine cycle (4) for energy transfer, for converting thermal energy to mechanical and/or electrical energy.

A cryogenic and thermal source cogeneration apparatus for converting energy from a heat source, through a cryogenic heat transfer process, into mechanical and/or electrical energy is also disclosed, comprising, vapor compression cycle mechanisms to absorb heat from the heat source, and Rankine cycle mechanisms for energy transfer, for converting thermal energy to mechanical and/or electrical energy. The Rankine cycle mechanisms being operably linked to the vapor compression cycle mechanisms.
