摘要:
A method of inductively powering light fixtures through glass or other non-ferrous material is disclosed that results in the light fixture itself not needing wires for operation, thereby simplifying and lowering the cost of the installation process, and allowing for the fixture to be completely sealed and protected. Such light fixtures are useful for automotive and household or business decorative or advertising use.

This invention relates to the zonal transmission of data by optical means through the modulation of light from common building light fixtures, including the light output of fluorescent, mercury vapor, and other arc or discharge lamps and fixtures; a system for the reuse of radio frequencies by smart radios, and the accurate locating and tracking of objects or persons as they move through a building; by means of creating a communications system which exploits the existing infrastructure of a building to facilitate the transmission of relatively secure control and communications data via creation of a multiplicity of area-limited interference-free communication zones. The system facilitates the transmission of wide-area as well as zonal-specific data. The system facilitates the creation of a database that contains present location and history location and movement data of persons and objects as they move through a building.

This invention relates to the zonal transmission of data by the modulation of the light output of arc lamps or discharge lamps; including the visible or invisible light output of fluorescent lamps, mercury vapor lamps, high or low-pressure sodium lamps, metal-halide based lamps, or other arc or discharge lamps. The method results in an easily installed, easily maintained, and economical to purchase, optical-wave communications system which exploits the existing infrastructure of a building or facility to facilitate the transmission of data in individual zones; thereby facilitating the transmission of wide-area as well as zonal-specific data to compatible receivers, and further facilitating the determination of location of remote devices or users, and the delivery or exchange of information or data, utilizing limited range transmission techniques.
摘要:
The present invention provides improved processes for the chemical reduction of imide esters to the corresponding amino alcohols with yields greater than 76%. A specific range of ethereal to hydrocarbon solvent ratio is used. The improved yield can be achieved using as a reducing agent lithium aluminum hydride or the less costly sodium aluminum hydride in combination with an additive such as lithium chloride.
