Abstract: In a method of manufacturing an electronic package, first grooves are formed on a circuit structure and a second groove is formed in each of the first grooves to allow the circuit structure to become circuit layers. Owing to the second groove is narrower than the first groove, each of the circuit layers has an encircled surface and a notch located on the encircled surface. When a shielding layer is provided to cover an encapsulating body located on the circuit layer, a space of the notch is not covered by the shielding layer such that a portion to be removed of the shielding layer will not remain on the electronic package to become burr after removing the portion to be removed.

Abstract: A power generating device includes a power generating unit and a frame, wherein the power generating unit is connected to the frame by two outer casings with two respective arms. The power generating unit has an input shaft and a roller is mounted to the input shaft. The frame is connected to the exerciser and a shock-absorbing member is located beneath the frame. Two resilient members are connected to two ends of the frame and two ends of each resilient member are respectively connected to the frame and the power generating unit so as to urge the roller to contact against the energy transferring end. The shock-absorbing member absorbs vibration from the power generating unit. The users operate the exerciser and generate electric power.

Abstract: A display for an exercise device has a cylindrical housing formed from a rear half shell and a front half shell. The housing has an inner space and two open ends, and a support rod of the body-build can pass through the inner space and extend out from the open ends. A positioning hole is defined in the support rod, and a positioning stub corresponding to the positioning hole is formed in the inner space of the housing. The positioning stub is mounted in the positioning hole to prevent the housing from rotating on the support rod. Two fasteners are securely and respectively formed on the housing in the inner space fasten the rear and front half shell together to form the housing.
