Abstract: A modified polyurethane material and a method for manufacturing the same are provided. A dianhydride is added into an aliphatic diisocyanate to form a liquid reactant. A solvent is absent from the liquid reactant. An oligomerization is implemented onto the liquid reactant so as to form an oligomer having a terminal isocyanate group. A polyol and a curative are added into the oligomer having the terminal isocyanate group for a polymerization so as to form the modified polyurethane. Based on a total weight of the modified polyurethane being 100 wt %, a content of a hard segment of the modified polyurethane ranges from 15 wt % to 45 wt %.

Abstract: One aspect of the present invention is an infrared thermometer with an infrared sensor. The infrared thermometer is adapted for determining a temperature on at least one predetermined spot on or in a human or animal body and further comprises recognition means for recognizing if the sensor is properly positioned on said at least one predetermined spot. Further shown is a method of operating an infrared thermometer.

Abstract: A folding apparatus for a bicycle frame includes a bicycle frame and at least one engaging device assembled on the bicycle frame. The bicycle frame includes at least one first tube and at least one second tube. Each of the at least one engaging device includes a stationary sleeve disposed on the second tube and has a series of second tooth formed thereon. A rotary sleeve is fixed to the first tube and rotatably mounted on the second tube. The rotary sleeve has a series of first tooth formed thereon for correspondingly engaging with the stationary sleeve. A locking device is movably mounted on the second tube for securely retaining the rotary sleeve firmly engaging with the stationary sleeve. When the locking device is released, the rotary sleeve and the first tube rotate relative to the second tube, and the bicycle frame is folded.
