Appl. No.:

09/991082

Ihor Terence Wacyk - Briarcliff Manor NY
Ling Wang - Millwood NY
Johannes Hendrik Wessels - Mierlo, NL

Assignee:

Koninklijke Philips Eletronics N.V. - Eindhoven

International Classification:

G05F 100

US Classification:

315291, 315DIG 4, 315149, 315294

Abstract:

The invention is a new architecture for a high frequency (HF) ballast with wireless communication interface. The new architecture integrates the RF wireless interface into the ballast. A user control transmits an RF control signal to a second antenna at the ballast site which provides the RF signal to the ballast which activates the fluorescent lamp. The ballast includes a transceiver/receiver, a communication decoder, a power control stage and a power stage. The transceiver/receiver receives the RF signal and communicates it to the communication decoder which acts as an interface to the power stage control. The power stage control controls the power stage that activates the fluorescent lamp. The communication decoder, power control stage, power stage and transceiver/receiver are located within the ballast enclosure which is an important part of the invention. If the power stage control is digital it may be combined with the communication decoder into one microprocessor or digital controller such as an ASIC.

International Classification:

G08C 1900

US Classification:

34082552, 340 35

Abstract:

A system for implementing a method for initializing and binding ballasts is disclosed. The system comprises a remote control having a master controller and the ballasts each having a slave controller. The master controller and the slave controllers are operated to implement routines whereby the master controller generates a clock sequence of a plurality of clock cycles, and the slave controllers randomly generate addresses and direct a transmission of signals indicative of the generated random addresses to the master controller during corresponding clock cycles. In response thereto, the master controller assigns network addresses corresponding to the random addresses as indicated by the corresponding clock cycles. The master controller and the slave controllers are further operated to implement routines for verifying the assigned network addresses and routines for binding each network address to a command of the remote control.

Abstract:

A method of initializing system components of a wireless-controlled lighting system. The system components include a remote control and a plurality of lighting units which communicate with a control master for the system via commonly-received radio communications. In order to become part of the system, each component transmits a respective request for initialization. A local control master for the system responds to each request, in turn, by allocating and transmitting a unique ID code for the requesting component. It then transmits a verify command to the requesting component which, if it has received the ID code, signals the user affirmatively.

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

H01K001/62

US Classification:

315 33, 3151693, 315 86, 235472

Abstract:

The present invention provides a structure, method, computer program and a system for displaying information on a portable wireless device. This may be accomplished by receiving a light signal containing embedded data and converting the signal into electrical power. It may also be accomplished by demodulating the embedded data, retrieving information from the database in the storage device and displaying the information on a Light Emitting Polymer display screen.

Appl. No.:

10/539983

Inventors:

Demetri Giannopoulos - Norwalk CT, US
Ling Wang - Millwood NY, US

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

G08B 1/08

US Classification:

34082572, 398106

Abstract:

A method for associating a group of lighting units in a wireless-controlled lighting system to respective buttons or other control elements on a remote control. Each of the lighting units transmits, via modulation of its own illumination light, a unique identification code for the respective unit. The remote control is successively positioned to receive the modulated light from each lighting unit and, at each position, the user activates a respective control element of the remote control for association with the lighting unit. The remote control then transmits to a control master for the group the unique codes and codes identifying the respective control elements with which they have been associated.

US Classification:

315317, 315321, 307 40

Abstract:

The present invention provides a master-slave architecture for a radio frequency RF networked lighting control system having all slave elements (ballasts) configured as backups for a network master control unit. In the system and method of the present invention a slave element can become the network master network unit without reconfiguring the network and without any human intervention. Similarly, both a master and one or more slave elements may recover from a temporary outage without necessitating reconfiguration of the network and without any human intervention.
