Patent number: 8260575Abstract: A network operation center for a light management system having networked intelligent luminaire managers. A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires and third-party devices to a network server. The luminaire managers communicate with each other, whereby they form a network.Type: GrantFiled: July 28, 2011Date of Patent: September 4, 2012Assignee: ABL IP Holding LLCInventors: Jeff D. Walters, Charles J. Darnell, Zachary S. Gibler, David A. Henderson, Michael M. Minarczyk, William Eric Holland

Patent number: 7471123Abstract: A baseband clock synthesizer having particular use in a BLUETOOTH piconet device, having the capability of generating either 12 MHz or 13 MHz clock signals generated from any reference clock signal, e.g., 12.00, 12.80, 13.00, 15.36, 16.80, 19.20, 19.44, 19.68, 19.80, and 26.00 MHz. A fractional-N frequency divider is implemented with a PLL including a variable divider allowing the use of virtually any reference frequency input to generate a locked 156 MHz clock signal used as a basis for a 12 MHz or 13 MHz baseband clock signal. A residue feedback sigma-delta modulator provides a varying integer sequence to an integer divider in a feedback path of the PLL, effectively allowing division by non-integer numbers in the PLL. Thus, the PLL can be referenced to virtually any reference clock and still provide a fixed output clock signal (e.g., 12 or 13 MHz).Type: GrantFiled: April 20, 2005Date of Patent: December 30, 2008Assignee: Agere Systems Inc.Inventors: William Eric Holland, Wenzhe Luo, Zhigang Ma, Dale H.
