  • Publication number: 20200400773
    Abstract: Embodiments of this disclosure provide techniques used in a location sensing service and a timeline service implemented in a host device for providing location history. In particular, the location sensing service may passively collect location coordinates of the device using requests made by third party applications. The location sensing service may receive a signal comprising an intent for a location request in response to a change in the user activity or in response to a change in a cellular identification of the device. The device may determine that a time elapsed from a previous location request and a time corresponding with receiving one or more of the signals exceed a time threshold and, based thereon, request a location coordinate of the device.

  • Publication number: 20190307893
    Abstract: The application relates to liposomal nanovesicles comprising porphyrin-lipid conjugates within the liposomal lipid bilayer. Said porphyrin-lipid conjugate comprise porphyrins that are modified with a —CH(R1)—O—R2 group and that chelate a metal ion. Such modifications of the porphyrin allow for ordered assembly in the lipid bilayer of the nanovesicles while resulting in a bathochromic shift in the wavelength of light absorbed by the porphyrin chromophore. These nanovesicles can be used for photothermal therapy, photodynamic therapy, photoacoustic imaging and fluorescence imaging. The application also teaches methods for preparing the porphyrin-lipid conjugates and the nanovesicles.
