    摘要： This invention relates to a light delivery and collection device for performing spectroscopic analysis of a subject. The light delivery and collection device comprises a reflective cavity with two apertures. The first aperture receives excitation light which then diverges and projects onto the second aperture. The second aperture is applied to the subject such that the reflective cavity substantially forms an enclosure covering an area of the subject. The excitation light interacts with the covered area of the subject to produce inelastic scattering and/or fluorescence emission from the subject. The reflective cavity reflects the excitation light as well as the inelastic scattering and/or fluorescence emission that is reflected and/or back-scattered from the subject and redirects it towards the subject. This causes more excitation light to penetrate into the subject hence enabling sub-surface measurement and also improves the collection efficiency of the inelastic scattering or fluorescence emission. The shape of the reflective cavity is optimized to further improve the collection efficiency.

    摘要： Identifying a location of a mobile device is disclosed (e.g., presuming user consent to the same). One or more received signal strengths (RSSs), comprising a first RSS, may be received by a first access point (AP) from the mobile device. The RSSs may be used to identify a grid area, comprising a first grid space. A signal distance between the first grid space and the first AP may be identified using the first RSS, and combined with a first grid space distance, comprising a known distance between the first grid space and the first AP, to determine a first grid space likelihood score for the first grid space. A second grid space likelihood score may be determined for a second grid space (e.g., and a third, etc.), and the grid space comprising a desired grid space likelihood score (e.g., highest) may be selected as the mobile device location.
