摘要:
A system and method for measuring air quality using a micro-optical mechanical gas sensor is disclosed. According to one embodiment of the present invention, the system includes an emission source that includes a conduit gap for receiving a gas; a plurality of electrodes for applying an electric field to at least a portion of the conduit gap, the application of the electric field creating a plasma in the conduit gap; and a detector that detects an emission from the plasma. The emission source and the detector may be micro-optical mechanical devices. A method for measuring air quality is discloses. According to one embodiment, the method includes the steps of (1) placing a chip containing an emission source and a detector in a gas flow; (2) applying an electric field to at least a portion of a conduit gap within the emission source, the electric field creating a plasma; (3) detecting an emission from the plasma; and (4) processing data related to the detected emission to determine at least one constituent of the gas flow.

摘要:
An adapter, used with a spark plug body and an engine block, is disclosed. The body defines an axis and has adjacent one end, a coaxial metal ring. A coaxial metal tube extends from the ring towards the other body end and is threaded in said block in use. An insulator, having a portion inside the tube, extends axially, from inside the tube, beyond the ring, and has a void therethrough. A positive electrode occupies the void and extends axially beyond the insulator to a terminus. In use, the adapter is secured to said body and comprises: a positive electrode extender in electrically-conducting relation to the positive electrode and a ground electrode extender in electrically-conducting contacting relation to the ring. The adapter is configured such that a gap defined between the positive and ground extenders comprises a channel which opens axially away from said body and is substantially unobstructed axially.

A method of constructing a spark plug that has positive and ground electrodes configured such a spark plug defined between the positive and ground electrode extenders comprises an elongate channel which opens axially and away from the body and is substantially unobstructed in the axial direction to provide better ignition resulting in improved fuel economy. The method involves taking a body part of a conventional spark plug and welding an adapter part to the body part to produce a spark plug with the elongate channel.

A photonic crystal, and a photonic device having such a photonic crystal, configured by changing its physical geometry in at least one region to alter light propagation and/or confinement. The configuring means may include electrostrictive, piezoelectric or magnetostrictive components of the photonic crystal, or an actuation device affixed to the photonic crystal.
摘要:
A radioisotope-powered semiconductor battery comprises a substrate of a crystalline semiconductor material, the material having at least one degree of confinement, and a radioactive power source comprising at least one radioactive element. The power source is positioned relative to the substrate to allow for impingement of emitted particles on the substrate. The semiconductor material may be electronically, structurally or chemically confined. The radioactive element is preferably impregnated within or immediately adjacent the semiconductor material.
