Application of Broadcast FM for Utility Energy Management Communications
Technological and economic aspects of various approaches to electric utility Energy Management communications for remote control are discussed. Communication systems employing radio frequency (RF) transmission techniques are treated in some detail with comparisons being made between narrow- band VHF transmitter systems, those systems utilizing a portion of AM broadcast radio channels and systems using a portion of FM broadcast radio channels. Finally, typical utility energy management applications of these-systems are discussed.
A low-cost microcomputer based direct load control scheme for small electric utilities
Abstract A low-cost microprocessor based direct load control scheme is described. The scheme is particularly suitable for small- to medium-sized public utilities which do not possess large financial resources to implement a large-scale SCADA based load management system. The system is designed around the 8-bit 68HC11 microcontroller manufactured by Motorola. The hardware consists of two basic systems: the transmitter and the receiver. The transmitter consists of a PC, and HC11 Evaluation Board and a radio transmitter. The receiver consists of the radio receiver and an HC11 running in single-chip mode. The system uses an addressing scheme to control up to four loads at each of 4095 different receiver sites. It uses redundant data transmission to ensure error-free operation.
Working Knowledge: Employee Innovation and the Rise of Corporate Intellectual Property, 1800-1930
This book presents the legal and business history of corporate ownership of employee knowledge. Skilled workers of the early nineteenth century enjoyed a degree of professional independence because workplace knowledge and technical skill were their 'property,' or at least their attribute. In most sectors of today's economy, however, it is a foundational and widely accepted truth that businesses retain legal ownership of employee-generated intellectual property. In "Working Knowledge", Catherine Fisk chronicles the legal and social transformations that led to the transfer of ownership of employee innovation from labor to management. This deeply contested development was won at the expense of workers' entrepreneurial independence and ultimately, Fisk argues, economic democracy. By reviewing judicial decisions and legal scholarship on all aspects of employee-generated intellectual property and combing the archives of major nineteenth-century intellectual property - producing companies - including DuPont, Rand McNally, and the American Tobacco Company - Fisk makes a highly technical area of law accessible to general readers while also addressing scholarly deficiencies in the histories of labor, intellectual property, and the business of technology.
