Abstract: A method for evaluating a biological effect of far infrared (FIR) includes the following. An FIR radiation source is provided to emit FIR. An FIR biological effect index (FBI) of the FIR is measured. A ratio of a blood glucose level change of an experimental group irradiated with the FIR to a blood glucose level change of a control group not irradiated with FIR is defined as the FBI. When the FBI is greater than 1, it is evaluated that the FIR causes a biological effect on an organism.

Abstract: A far-infrared emitters with physiological signal detection and method of operating the same is disclosed. A far-infrared beam module is switched on and generates far-infrared beam irradiating to a human body when a control unit starting up a microwave detecting module detecting physiological signal of the human body. The control unit is switched off when the time that the far-infrared beam irradiating on the human body reach a presetting period of time, thereby achieving the purpose of energy conservation.

Abstract: Disclosed in the present invention is an unfolded life jacket which comprises a fixed floating body provided with a notch through which a user's head passes; straps comprising interconnecting straps attached to the fixed floating body, the interconnecting straps being tied with intermeshing loop straps to hold the user's body; a movable floating body comprising a front movable floating block and a rear movable floating block, to which the fixed floating body is attached, respectively, a rope being attached to the front movable floating block and the rear movable floating block, the rope being tied with the intermeshing loop straps, an adhesion part limiting the front movable floating block and the rear movable floating block on the intermeshing loop straps. It helps the user to keep in a vertical state in water so as to stabilize the gravity center and keep the head out of the water surface.

Abstract: A golf bag with retractable wheels includes a golf bag, retractable mechanisms, wheels and a supporting rod. The golf bag comprises a pair of recesses at respective bottom sides to accommodate the retractable mechanisms and the wheels. Each retractable mechanism has one end connected to one relative wheel, while the other end of which is secured to the bottom of the golf bag. Thus, the wheels may be extended outwardly from the recesses of the golf bag for strolling, and the supporting rod is able to support the golf bag standing still when not in moving.

Abstract: A compound putter with variable angles is composed of a shaft, a head, a putter face and a chipper face characterized by that a transverse through hole having its both outer sides respectively provided with an elastic washer is disposed at the lower end of the shaft adapted to a pivot; a recess in the upper side of the head to receive the lower end of the shaft and a through hole each provided in both sides of the recess so that with the lower end of the shaft in the recess and the pivot penetrating the through holes in the head and in the shaft to pivot the shaft to the head then a putter face and a chipper face are provided on both sides of the head.
