A system, including reconfigurable optical cable splice for splicing optical cables, that does not require any direct handling of the optical fiber is described. A binary sequence is debinarized by traversing one of the tree structures to determine a corresponding symbol. The method can include making a determination on the inclination amount based on a predetermined condition. A slot positioned in the inductive sensor may be used to tune a resonant mode of the inductive sensor to accurately and particularly detect metallic shanks andor other metallic objects in shoes, socks, andor clothing.
