Abstract: The present disclosure discloses salts formed by 2-(1-acyloxy-n-pentyl)benzoic acid and basic amino acid or aminoguanidine, a preparation method thereof, pharmaceutical preparations containing these salts, and application thereof in preparation of drugs for preventing or treating ischemic cardiovascular and cerebrovascular diseases, resisting thrombosis and improving cardio-cerebral circulation disorders. The compound of the present disclosure has excellent water solubility, aqueous solution stability and pharmacokinetic properties, also has significant anti-platelet aggregation, anti-thrombosis, anti-cerebral ischemia and neuroprotective activity.

Abstract: Embodiments described herein provide various examples of real-time visual object tracking. In another aspect, a process for performing a local re-identification of a target object which was earlier detected in a video but later lost when tracking the target object is disclosed. This process begins by receiving a current video frame of the video and a predicted location of the target object. The process then places a current search window in the current video frame centered on or in the vicinity of the predicted location of the target object. Next, the process extracts a feature map from an image patch within the current search window. The process further retrieves a set of stored feature maps computed at a set of previously-determined locations of the target object from a set of previously-processed video frames in the video. The process next computes a set of correlation maps between the feature map and each of the set of stored feature maps.

Abstract: The application relates to a pedal mechanism and a housing of a balancing vehicle. The pedal mechanism comprises a pedal body, and an internal framework is arranged inside the pedal body. A lower side of the pedal body is also formed with an induction probe for inducting a control system inside a balancing vehicle. A housing of the balancing vehicle comprises a pair of symmetrically arranged and relatively rotatable inner housings, the inner housings are connected with the upper housing, and the pedal mechanism installed at upper housing. The pedal body and the induction probe are integrally molded, which has the advantages of less multiple assembly processes, shorter processing time, higher precision, and not easy to fall off which strengthens the stability of the structure.

Abstract: Embodiments described herein provide examples of a real-time visual object tracking system. In one aspect, an unmanned aerial vehicle (UAV) capable of performing real-time visual tracking of a moving object includes: a processor; a memory coupled to the processor; and a camera to capture a video of the moving object. This UAV additionally includes a visual tracking module to: receive a first video image and a first location of the object; receive a second video image following the first video image; place a first search window in the first video image and a second search window in the second video image centered on a second location in the second video image having the same coordinates as the first location; compute a correlation between an image patch within the first search window and an image patch within the second search window; and determine an updated location of the object in the second video image.
