Abstract:

A composition of material for making a glow-in-the-dark powder and glaze as well as a process for manufacturing a glow-in-the-dark ceramic. The glow-in-the-dark powder consists of aluminum oxide, strontium carbonate, rare earth, and carbon. The glow-in-the-dark glaze consists of red lead, quartz, zinc oxide, glaze melting block, calcite, Suzhou earth, stannic oxide, limestone, and the glow-in-the-dark powder. The glow-in-the dark powder is first sintered and then grinded to fine powder. The powder is then added to the glow-in-the-dark glaze and stirred vigorously to form a paste that can be applied to ceramic products which are to be sintered to form the final glow-in-the-dark ceramic products.

Abstract:

Electrical power for an electrical device can be acoustically produced. A first portion of an acoustic energy can be received at a piezoelectric transducer. A first electrical energy, produced from the first portion of the acoustic energy, can be conveyed from the piezoelectric transducer and received by a circuit. A bias voltage, produced from the first electrical energy, can be conveyed from the circuit and received at a capacitive transducer. A second portion of the acoustic energy can be received at the capacitive transducer. A second electrical energy, produced from the second portion of the acoustic energy, can be conveyed from the capacitive transducer and used as the electrical power for the electrical device. A ratio of the second electrical energy to the second portion of the acoustic energy can be greater than a ratio of the first electrical energy to the first portion of the acoustic energy.
