Abstract: The invention provides a process for the preparation of a multimodal ethylene polymer in a multistage process in the presence of a catalyst comprising a complex of formula (lx) wherein each X is a sigma donor ligand; each Het is independently a monocyclic or multicyclic heteroaromatic or heterocyclic group containing at least one heteroatom selected from O, N or S; L is a carbon, silicon or germanium based divalent bridge in which one or two backbone atoms link the ligands; M is Ti, Zr or Hf; each R1 is the same or different and is a linear CMO alkyl group, or linear CHO alkoxy, each n is 0 to 3; each R2 is the same or different and is a C1-10 alkyl group, C1-10 alkoxy group or —Si(R)3 group; each R is the same or different and is C1-10 alkyl or phenyl group optionally substituted by 1 to 3 C1-6 alkyl groups; and eachp is 0 to 3;

Abstract: Disclosed herein are systems and techniques to adapt an image to a gaze vector of a user or project content based on a distance between an appendage of a user and a at least a portion of a projected image. The system can include a projector to project an image and a camera to capture an image. The system can determine a gaze vector of a user and adapt the projected image based on the gaze vector. Additionally, the system can determine a distance between an appendage of the user and the projected image and project content based on the distance.

Abstract: The present invention relates to proximity sensors. It also relates to proximity sensors in electronic devices using lightguides. More specifically the invention relates to a simple self monitoring of optical proximity sensors. This can be achieved according to one embodiment of the present invention by a system of lightguides for the use in proximity sensor. The lightguide system comprises a transceiver lightguide to direct-transmitter to a predefined direction, and a receiver lightguide to direct transmitter light reflected from an object towards a receiver, where the transceiver and receiver lightguides comprise diffracting surfaces to direct a part of-the light from the transmitter as a self monitoring beam in a direction towards a receiver.
