Abstract: A method for object tracking. The method includes capturing, using a camera device, a sequence of images of a scene, detecting, based on a pattern of local light change across the sequence of images, a light source in the scene, comparing, in response to detecting the light source, a location of the light source in at least one image of the sequence of images and a target position within the at least one image to generate a result, and generating, based on the result, a control signal for changing a field-of-view of the camera device such that the light source substantially aligns with the target position within the field-of-view.

Abstract: Disclosed is a completely recyclable artificial turf, which solves the problem of difficult totting of the existing artificial turf, has high tufting efficiency, has high strength of artificial turf, and is capable of being integrally recycled. The completely recyclable artificial turf of the present invention comprises artificial yarn and base fabric, wherein the base fabric includes woven fabric, the artificial yarn is tufted on the base fabric including woven fabric, the root of the artificial yarn is melted or locally melted, and the artificial yarn is integrated with the base fabric into a whole after cooling and shaping, wherein the material of the artificial yarn has a melting point lower than that of the material of the base fabric.

Abstract: Methods and compounds for treating obesity and inducing weight loss use a functional, glycosylated leptin transport factor (LTF) polypeptide, referred to as fn/glyLTF. An unstable defective version of the LTF protein, referred to herein as def/LTF, is present in freshly-drawn blood from obese animals or people; it is degraded rapidly in circulating blood. In people with normal body weight, fn/glyLTF stabilizes and protects leptin, a hormone with powerful effects on fat metabolism and body mass. LTF apparently is the same protein previously recognized as a soluble truncated fragment of the obesity receptor (Ob-R) protein, referred to in the prior art as Ob-Re, or sOb-R. In humans with normal body weight, fn/glyLTF has a weight of about 145 kD, compared to a polypeptide-only weight of about 93 kD. defLTF has a substantially lower molecular weight, and tests using deglycosylating enzymes indicate that it is not glycosylated to the same level as fn/glyLTF.
