Abstract: A correlation system (100) is disclosed, for use with a lighting system (102). The lighting system (102) is associated with one or more wands (104) so as to initially configure or reconfigure relationships and correlation among switches and lights of the lighting system (102). The lighting system (102) includes a plurality of lighting units (106). The lighting system (102) also includes a plurality of switch units (128). The wand (104) includes an IR emitter (160) to transmit signals to said lighting units (106) and to said switch units (128) so as to effect controlling relationships among the switch units (128) and lighting units (106).

Abstract: A simple and efficient method for producing an obfuscated speech signal which may be used to mask a stream of speech, is disclosed. A speech signal representing the speech stream to be masked is obtained. The speech signal is then temporally partitioned into segments, preferably corresponding to phonemes within the speech stream. The segments are then stored in a memory, and some or all of the segments are subsequently selected, retrieved, and assembled into an obfuscated speech signal representing an unintelligible speech stream that, when combined with the speech signal or reproduced and combined with the speech stream, provides a masking effect. While the presently preferred embodiment finds application most readily in an open plan office, embodiments suitable for use in restaurants, classrooms, and in telecommunications systems are also disclosed.
