US Patent:

7511613, Mar 31, 2009

Filed:

Jan 11, 2005

Appl. No.:

10/597078

Inventors:

Ling Wang - Chicago IL, US

Assignee:

Koninklijke Philips Electronics, N.V. - Eindhoven

International Classification:

G08B 1/08

US Classification:

34053926, 34053922, 34053923, 3405391, 340540

Abstract:

In illuminated local areas occupants are actively detected to facilitate control of the illumination and possibly other local parameters such as temperature. The emitted light in each local area is uniquely modulated to identify the respective area. The modulated light is detected by any wearable occupancy detectors in the local areas, which transmit detector-locator signals to lighting control units, thereby identifying which local areas are occupied. These signals may also uniquely identify the respective detectors, thereby enabling a lighting system controller to determine the number and identities of the detectors in each local area.

Assignee:

Koninklijke Philips Electronics, N.V. - Eindhoven

International Classification:

H04B 1/40

US Classification:

455 88

Abstract:

A communication network includes a plurality of devices and a control unit for generating control signals to control the operation of the devices. Each device includes: a device operating circuit, a communication interface for receiving command signals for controlling operation of the devices, a control circuit coupled between the device operating circuit and the communication interface for controlling the operation of the device operating circuit part in dependency of said command signals, and a master integral to the device for receiving the control signals, for generating the command signals in response to the received control signals, and for transferring the command signals to the communication interfaces of the plurality of devices. The communication network activates one of the masters as an active master, and in case the active master fails, then it activates another master to take over as the active master.

Abstract:

A network () employs a wireless network topology (), a wireless network manager (). Network () further employs a wireless device () and wireless device manager () pairing and/or a wireless system () and a wireless system manager () pairing. Managers () cooperatively control an operating profile and monitor an operational status of the device (). Managers () cooperatively control an operating profile and monitor an operational status of system (). Manager () can be installed on a computer () and wirelessly communicate within network () via a wireless control device () employing a port connector () that can be plugged into a port () of the computer (). Device () or system () can implement a digital ballast () that determines an average power consumption of the digital ballast () drawn by a power interface () of digital ballast ().
