There is provided a wide-band LSP prediction device and others capable of predicting a wide-band LSP from a narrow-band LSP with a high quantization efficiency and a high accuracy while suppressing the size of a conversion table correlating the narrow-band LSP to the wide-band LSP. Crossbar andor barrel shifter circuitry may replace one or more rows, one or more columns, one or more rectangles, or any combination thereof of programmable logic regions on a programmable logic resource. In certain embodiments signal emitting elements carried on the vehicle emit signals towards the presumed position of the cavity wall, and sensing elements carried on the vehicle receive the emitted signals after they are reflected off of the cavity wall. The generator employs the statistical treatment to present a new sequence. Some embodiments of the present invention include a handle comprising an ergonomic grip and a guard.
