Abstract: Disclosed is a power-driven shoe. The shoe includes a shoe sole having a plurality of rotatable wheels arranged below the shoe sole in an overlapping fashion. The distance between the rotational axis of the wheels is less than or equal to the diameter of the wheel, such that vertical obstacles can be overcome in both the positive and negative displacement directions for increased ground stability. The shoe sole includes a toe part and a sole part that are connected to each other, via a hinge, in both a rotational and translational configuration, such that at least one front wheel or at least one middle wheel are independently in contact with the ground while maintaining at least one rear wheel in contact with the ground throughout a bi-pedal gait cycle, allowing for comfort during a user's natural range of motion.

Abstract: A system for control of a mobility device comprising a controller for analyzing data from at least one sensor on the mobility device, wherein the data is used to determine the gait of user. The gait data is then used to provide motion command to an electric motor on the mobility device.

Abstract: The present invention relates to the field of chemical analysis detection and application, in particular to a marker peptide of snake venom thrombin-like enzymes (SVTLEs) from Agkistrodon Halys Pallas and an application thereof. The amino acid sequence of the marker peptide of snake venom thrombin-like enzymes (SVTLEs) from Agkistrodon Halys Pallas is TLCAGVMEGGIDTCNR. Characterizing the source of species and a content of the SVTLEs in a to-be-detected sample by using the marker peptide includes the following steps of: pretreating the to-be-detected sample by trypsin through enzymolysis, and taking a supernatant of an enzymolysis liquid as a test solution; and injecting the test solution and a reference solution into a liquid chromatography-mass spectrometer, and selecting a qualitative ion pair and a quantitative ion pair for detecting the source of species and a content of the SVTLEs in the to-be-detected sample.

Abstract: A mobility device comprising a motorized shoe to be worn by a user to increase the speed of walking. The motorized shoe has a plurality of wheels, with at least one wheel driven by an electric motor through a geartrain. On onboard controller gathers data from at least one of an inertial measurement unit, an ultrasonic sensor, and a vision system to generate a command speed to the electric motor. A user wearing a pair of the mobility devices, one on each foot, is able to walk with a normal gait, but at an increased speed.
