A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for receiving at least N different summations of the M source signals. In accordance with one embodiment, a feature may be extracted from a biometric sample captured from a claimant claiming an identity. The system utilizes an error-correcting code for decommitting the item if a second set of elements has a specified level of overlap with the first set of elements. The throat is positioned above the cushion portion. There is no extra Application Programming Interfaces required to pass information between the text editor and a spellchecking engine in order to perform keyboard layout detection. Taking advantage of fast paths can improve the execution times for typical blocks.
