Abstract: Electronic arrangement for positioning a mobile device, including a mapping entity configured to obtain positioning data, from a plurality of measuring mobile devices present in an area of interest, establish and maintain, based on the obtained data, a multi-level probability map model structure for the area, wherein each higher level covers the area with lower spatial resolution by a plurality of determine sub-areas, each having a unitary character, and each lower level correspondingly covers, for each the sub-area of the adjacent upper level, a plurality of determined sub-areas thereof with higher spatial resolution, the lowest level determining the highest spatial resolution location elements of the model, optionally coordinates, a locating entity configured to obtain data provided by the mobile device, determine an estimate of the position of the mobile device by traversing through at least a portion of a number of vertical candidate paths of the multi-level probability model structure.

Abstract: The invention relates to a headwear piece comprising a crown defining an opening to accept the head of a wearer. The crown has peripheral crown wall having an annular configuration and a top wall. The headwear piece has a first opening through the crown to allow passage therethrough of a first ponytail on the head of a wearer with the headwear piece in place on a wearer's head and a second opening through the crown wall to allow passage therethrough of a second ponytail on the head of a wearer with the headwear piece in place on a wearer's head. The first opening and the second opening are provided with enlarging means for enlarging the openings to produce enlarged openings through the crown facilitate the placement of a ponytail trough the openings.
