  • Publication number: 20180231560
    Abstract: This disclosure provides compositions and methods for the isolation of cells that express c-MET, and in particular circulating tumor cells that express c-MET. The methods can include contacting a biological sample including a c-MET circulating tumor cell with an unbound complex including a capture binding species linked to a solid phase for a time sufficient to allow the unbound complex to bind an extracellular binding domain of the c-MET protein to form a bound complex, and subsequently isolating the bound complex. Compositions, systems, and kits adapted for use with these methods are also provided.

  • Patent number: 9805592
    Abstract: This presentation provides methods to track pedestrians heading angle using smart phone data. Tracking heading angle especially at or from stationary position is key for pedestrian safety, e.g., for smart cross system and pedestrian collision mitigation system. It provides pedestrian-to-vehicle (P2V) platform. It deploys smart phones or mobile devices, equipped with DSRC (Dedicated short range communication) support, to act as beacons for pedestrians: Phone can alert driver to pedestrian presence in path; Pedestrian Basic Safety Message (BSM) can aid awareness for vehicles; It can be used for bicycles, as well. It also provides pedestrian-to-infrastructure (P2I) platform. Smart phone, through DSRC/cellular, transmits pedestrian presence to crosswalks/signals: It enables advanced crosswalk lighting/warning scheme; It enables bundling of pedestrian presence to vehicles. In this presentation, we provide various examples and variations on these.
