An aspect of the invention is a split leather product provided with a base material comprising split leather, and a skin layer laminated on a surface of the base material. The skin layer comprises a composite body of an entangled nonwoven fabric formed from microfine fibers, and a polymeric elastomer that impregnates the gaps in the entangled nonwoven fabric. The entangled nonwoven fabric in such a split leather product has the effect of increasing physical strength without detracting from a leather-like texture, in the same way as the longitudinally and transversally crisscrossing collagen fibers in the reticular layer. It is thus possible to obtain a split leather product that resembles leather not only in outward appearance but also in the feel derived from wrinkles and the like resulting when the leather is bent.

The display device includes an anti-reflection film having a plurality of projections over a display screen surface and a protective layer filling a space between the projections. The number of times of incidence of external light entering the display device on the anti-reflection film is increased; therefore, the amount of external light transmitted through the anti-reflection film is increased. Thus, the amount of external light reflected to a viewer side is reduced, and the cause of a reduction in visibility such as reflection can be eliminated. Further, since the plurality of projections is covered with a protective layer, entry of dust can be prevented, and physical strength of the anti-reflection film can be increased.

A physical activity measuring system analyzes analyzing body motions of a user to accurately determine the exercise intensity. The system includes a portable device which is adapted to be carried by the user and is equipped with a body sensor and an indicator for indication of the exercise intensity. The body sensor senses the user's body motions to give corresponding motion strength.
