摘要:
An exemplary system includes a first fuel cell capable of providing an electrical output, a second fuel cell capable of providing an electrical output, and a switch circuit that includes one or more switches for arranging the electrical output of the first fuel cell and the electrical output of the second fuel cell in parallel or series to thereby adjust electrical output efficiency and heat production.
摘要:
Tunnel-junction structures are fabricated by any of a set of related methods that form two or more tunnel junctions simultaneously. The fabrication methods disclosed are compatible with conventional CMOS fabrication practices, including both single damascene and dual damascene processes. The simultaneously formed tunnel junctions may have different areas. In some embodiments, tub-well structures are formed with sloped sidewalls. In some embodiments, an oxide-metal-oxide film stack on the sidewall of a tub-well is etched to form the tunnel junctions. Memory circuits, other integrated circuit structures, substrates carrying microelectronics, and other electronic devices made by the methods are disclosed.
摘要:
A piezoelectric actuator includes a cantilever membrane. A thin film sheet is affixed to one side of the cantilever membrane to bend the membrane in multiple directions in response to an electric field induced within the thin film sheet. A plurality of coplanar electrodes disposed on the thin film sheet are interdigitated in relation to one another to generate the electric field during application of a voltage across interdigitated electrodes.

摘要:
A piezoelectric printhead and related methods provide a first metallic electrode and a second metallic electrode deposited over a top surface and a bottom surface, respectively, of a piezoceramic plate. The second electrode is segmented into a plurality of electrode segments. A diaphragm is positioned over a plurality of pressure chambers, where the diaphragm includes a conductor positioned over each chamber. The piezoceramic plate is attached to the diaphragm such that each conductor on the diaphragm faces multiple electrode segments.
摘要:
A reflector for use in a projection system comprises an anodized metal substrate having a metal oxide layer. The metal oxide layer has a plurality of pores. A light absorbing pigment is deposited into each of the pores such that the light absorbing pigment and the metal oxide layer form a light absorbing layer on the metal substrate.
