Abstract: A push-up exercise device with height adjustment includes two bases and a grab rail mounted to and located between the two bases. Each base is provided with a mounting hole at a center of the base and a positioning piece in the mounting hole. A plurality of mounting slots with different lengths are disposed inside a mounting rod of the grab rail, extending from an open end of the mounting rod and corresponding to the positioning piece. The positioning pieces are configured to be aligned with and mounted into different lengths of the mounting slots to adjust a height of the grab rail of the push-up exercise device and in order to train different muscle groups and further shape a body of a user and improve the fitness of the user.

Abstract: An interlocking fitness roller is disclosed. The ends of a column-shaped roller body comprise retaining holes and locating holes. A hollow cylindrical assembly is inserted into a hollow interior of the column-shaped roller body. The hollow cylindrical assembly connects with elastic pieces, and each elastic piece comprises a retaining block and a positioning pin, which are respectively engaged with the retaining hole and the locating hole of the column-shaped roller body. The surface of the column-shaped roller body is covered by a pad. Accordingly, depending on different uses, the length of the interlocking fitness roller is adjustable. Two column-shaped roller bodies are connected by respectively engaging the retaining blocks and the positioning pins of the elastic pieces with the retaining holes and the locating holes, so as to is prevent the connection from becoming loose during rolling, thereby ensuring the robustness of the connection between the column-shaped roller bodies.

Abstract: A bonding stress testing arrangement and a method of determining stress are provided. The bonding stress testing arrangement includes at least one bond pad; a sensor assembly comprising any one of a first sensor arrangement, a second sensor arrangement and a combination of the first sensor arrangement and the second sensor arrangement; wherein the first sensor arrangement is adapted to measure an average stress on a portion of a bonding area under the at least one bond pad, and the second sensor arrangement is adapted to determine stress distribution over a portion or an entire of the bonding area under the at least one bond pad.
