This disclosure provides a voice-operated remote control intended to replace multiple entertainment system remotes, and it preferably includes two parts, a base unit and a remote unit. The device may include a die with its backside mounted to the bottom side of a multi-layer packaging substrate. The method additionally provides the player with the option to randomly determine a symbol or symbols a second time, or to force a symbol to be the same as a symbol already determined, optionally at additional cost. A first azimuth detector detects, within a first azimuth detection area whose angular range is defined by d1, the azimuth of a target based on the signals generated by all the first antenna elements. A predominantly digital technique is described in which a digital algorithm observes patterns in the sign of the amplifier output and drives a digital-to-analog converter, which reduces the amplifier’s offset. If the tag type is simple, a class diagram is generated for the data and then the source code for the data is generated.
