The present invention provides a splittable multicomponent fiber containing at least two polymer components arranged in distinct non-occlusive segments across the cross-section of the fiber, wherein the segments are continuous along the length of the fiber, and wherein at least one of the polymer components comprises about 10 percent to about 95 percent by weight of filler material. In this construction, there can be prevented breakage of thermoelectric device by thermal stress occurring at assembly, or thermal stress occurring at pre-tinning conducted in advance for attaching an object to be cooled or at attaching package, etc. For certain example implementations, a method may comprise obtaining at a mobile device one or more signals comprising information indicative of a location thereof. The independent layer then communicates the queries to one or more data providers associated with individual data sources.
