Title: Lighting system power adapter
Inventor: SUMMERLAND DAVID THOMAS
IPC: H05B44/00
Filed: 2004-12-01
Abstract: A power adapter for an LED lighting unit has at least two independent electrical outputs 16a, 16b, 16c which supply power to LEDs 30a, 30b, 30c which may be of three colours red, green, and blue. A power monitoring circuit 12 measures the input power or the variations in the output of the mains supply as controlled by a lighting controller (dimming switch) 20 which varies the duty cycle of the mains supply. The power monitoring circuit 12 supplies a signal to a processor 13 which is programmed to output a control signal to an output power module 14 according to a lighting profile and the results of the monitoring. A power regulator endeavours to supply a constant output power for supplying the LEDs 30a, 30b, 30c down to an input duty cycle of 20% of the mains duty cycle. Lighting profiles are sequentially selected by a user operating the lighting controller down to a minimum and back up again. An initial lighting profile is preferably white light of varying intensity, and further profiles may include another colour of varying intensity or varying colours to create different moods. The adapter may be fitted to a conventional light fitting and controlled by a conventional phase control triac dimmer. The adapter therefore allows mood effect lighting and retrofitting of the adapter without additional switches or wiring circuits.

Title: Superimposing information on noise, or an independent signal, using codewords of a block code selected on the basis of correlation results
Inventor: TOMLINSON MARTIN
IPC: H04L5/00
Filed: 2005-06-27
Abstract: The invention is concerned with impressing information upon noise or an independent signal. As one example the invention could be used to transmit additional information on top of a broadcast signal. The basis of the invention is that codewords from an (n, k, dmin) error correcting code are correlated against the noise, or the independent signal, and the codeword with the maximum correlation determined. Other codewords are derived from this codeword together with the values of their cross correlation with the noise or independent signal. According to the data information to be conveyed, and these correlation values, the maximum correlation codeword together with the other codewords are separately weighted and added to the noise or independent signal to produce a marked waveform. The information data is recovered from the marked waveform by determining the codeword, from the same (n, k, dmin) error correcting code, which has the highest correlation with the marked waveform. Binary or non-binary error correcting codes may be used depending on the application.
