  • Publication number: 20180186391
    Abstract: Systems and methods for obstacle avoidance with a self-driving vehicle are provided. The system comprises a processor connected to the self-driving vehicle and a sensor in communication with the processor. The sensor is configured to detect objects. The processor is configured to receive a measurement of the self-driving vehicle's speed, and define a sensor region based on the speed. The processor can determine that an object detected by the sensor is within the sensor region, and then initiate a fail-safe routine. The sensor region may be defined based on a range parameter. The sensor region may be defined based on the stopping distance of the vehicle. The sensor region may be redefined when the vehicle's speed changes.

  • Publication number: 20180120418
    Abstract: The complex temporal-spatial variation of raindrop size distribution will affect the precision of quantitative precipitation estimation (QPE) produced from radar data, making it difficult to correct echo attenuation. This invention presents a method for regional attenuation correction of weather radar using a multiple microwave links (ML) network. By measuring the rain attenuation of multiple microwave links in a specific frequency, matching with the weather radar in time and space and processed with discretization. Based on a series of attenuation values of the microwave link network and combined iterations, the attenuation coefficient of each grids is obtained; the total attenuation value of the path is obtained by combining the distance between the radar and each grid point, by which the reginal attenuation of radar echo can be corrected by the ML network efficiently.

  • Publication number: 20170260575
    Abstract: This disclosure related to methods of detecting mechanical forces required to separate ligand and receptor interactions. In certain embodiments, this disclosure relates to methods of detecting mechanical forces between a ligand and receptor, where the ligand is immobilized on a surface using weaker forces. Ligand-receptor forces lead to dissociation of the ligand that can be detected and amplified. In certain embodiments, the disclosure relates to methods of detecting ligand and receptor interactions comprising linking a ligand to one of two binding partners, wherein the binding partners have attracting forces that are less than the forces between the ligand and a receptor of the ligand such that when the ligand binds the receptor, the binding partners will separate. Separation of the binding partners can be detected.
