Appl. No.:

09/991082

Inventors:

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.

International Classification:

H05B 41/00
H02J 3/14

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.

US Classification:

5483657, 5483561, 5483661, 5483791, 549429

Abstract:

The present invention relates to a method for identifying compounds that modulate the activity of p300/CBP. Compounds of the invention are identified by designing or screening for a compound which binds to at least one amino acid residue of the newly identified lysine-CoA inhibitor binding site, L1 loop, electronegative pocket, or electronegative groove of the HAT domain of p300/CBP and testing the compound for its ability to modulate the activity of p300/CBP. Compositions and methods for preventing or treating diseases or disorders associated with p300/CBP are also provided as is a method for producing a semi-synthetic HAT domain.

International Classification:

G06F 13/42

US Classification:

340825000

Abstract:

A lighting control system network and method of providing same including a remote control unit having a RF signal transmitter and a RF receiver and a number of lighting control units, each of the lighting control units having a RF signal transmitter, a RF receiver, and a lighting unit associated therewith. The remote control unit and the lighting control units are configured in a master-slave oriented network. One of the lighting control units is configured as a master in the network and the remaining lighting control units and the remote control unit are configured as slaves in the network. The lighting control units and the remote control units communicate bi-directionally with each other over RF wireless links. The network may include sensors for detecting an environmental or system parameter. Multiple instances of the lighting control network may be interfaced together to form a building-wide network.
