Appl. No.:

09/991082

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:

Lattice Semiconductor Corporation - Hillsboro OR

International Classification:

H03D 3/24

US Classification:

375376, 375374, 375375

Abstract:

In a digital filter of a DPLL (digital phase locked loop) for minimizing the bit error rate for multiple communications protocols, a first reloadable register portion stores a TBW (total bandwidth) value programmed into the first reloadable register portion through a first port, and a second reloadable register portion stores a DBW (differential bandwidth) value programmed into the second reloadable register portion through a second port. An upcounter generates an UPCNT value by counting up each UP signal pulse generated by a phase transition detector when a first phase of a SDIN (serial data input) signal leads a second phase of a current ACLK (recovered clock) signal. A downcounter generates a DOWNCNT value by counting up each DOWN signal pulse generated by the phase transition detector when the first phase of the SDIN (serial data input) signal lags the second phase of the current ACLK (recovered clock) signal. One of a FWD (forward) signal or a BWD (backward) signal are asserted or are both not asserted depending on the UPCNT value and the DNCNT value in comparison to the TBW value and the DBW value. Another clock signal having a leading phase from the current ACLK signal is selected as a new ACLK (recovered clock) signal when the FWD signal is asserted.

International Classification:

H03D 3/24

US Classification:

375376, 375374, 375375

Abstract:

In one embodiment of the invention, a phase selection unit for generating a recovered clock signal (SCLK), a phase select signal generator generates a phase select signals in response to a FWD signal and a BWD signal from a digital filter. The digital filter asserts the FWD signal if the phase of a SDIN (serial digital input) signal leads the phase of the recovered clock signal, and asserts the BWD signal if the phase of the SDIN (serial digital input) signal lags the phase of the recovered clock signal. A multiplexer receives a number of given clock signals arranged in a predetermined phase order and outputs selected first and second output clock signals, each being one of the given clock signals. A phase interpolator receives the selected first and second output clock signals from the multiplexer to generate the recovered clock signal having a phase that is phase interpolated between the phases of the first and second output clock signals.

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.
