Abstract: In accordance with an example embodiment of the present invention, a method is disclosed that comprises receiving a reference signal from each of at least two target neighbor cells via at least one receiving branch at a user equipment; estimating a timing range based at least on one of a timing advance for a serving cell and an inter-cell distance between the target neighbor cell and the serving cell; computing a reference signal time difference for the received reference signal from the target neighbor cell; and screening the computed reference signal time difference using the estimated timing range.

Abstract: A light distributing device (100) comprises a thin planar waveguide (10) and a waveguiding ridge (20). An incoming light beam (B1) coupled into the ridge (20) forms a second light beam (B2) waveguided in the ridge (20). The ridge (20) and the planar waveguide (10) have a common portion (23) such that light is further coupled from the side of the ridge (20) into the planar waveguide (10) through said common portion (23). Thus, optical power of a broad incoming beam (B1) may be effectively coupled to a relatively thin planar waveguide (10). The planar waveguide (10) may further comprise diffractive out-coupling elements (30) to direct light towards a display (400).

Abstract: An antenna having a plurality of resonant frequencies and including a ground plane having an edge; a feed point; a ground point; and an antenna track extending between the feed point and the ground point and comprising, in series connection, a first loop and a second loop wherein a least a portion of the first loop and a portion of the second loop are adjacent at least the edge of the ground plane.
