In a first aspect, a first method is provided. The synthesis signals for a loudspeaker as well as associated channel information will then be transmitted to respective loudspeaker modules via a transmission path, wherein every loudspeaker module obtains the synthesis signals and associated channel information intended for the loudspeaker associated to the loudspeaker module. The tumor cell of the hybrid corresponds to the tumor of the subject. In another example, a positive response notification may include environmental information regarding one or more environmental conditions present at or near the work site during the locate andor marking operation. The lighting assembly includes an LED and a solid reflector optic having a reflective surface shaped to reflect light from the LED in a way that produces the asymmetrical light ray angle distribution at least in part. These results lead to an optimal dynamic performance for a given spacing target and enhanced read gap protrusion at a given heater power.
