A method for performing neighbor discovery in a multi-tier wireless local area network where a client creates a neighbor list identifying a neighbor wherein the neighbor is identified as an access point or a client. The lock includes a housing attached to the vehicle door. The filter transmits radiation at a wavelength of 157 nm for exposing an image of a mask pattern on a resist-coated substrate whilst attenuating radiation resulting from fluorescence in optical components of the lithographic projection apparatus, caused by the imaging radiation, and which if not attenuated would reduce the contrast of the image exposed in the resist. Conditions not conducive to noninvasive measurement of glucose are detected.
