Abstract: A device for providing active assistance to a body joint including at least one spring module interconnecting first and second attachment parts. The at least one spring module including first and second elongate link members coupled to the first and second attachment parts respectively and pivotably coupled to each other at a pivot joint with a pivoting axis perpendicular to the first and second elongate link members; a coil spring extending longitudinally between the first and second elongate link members and across the pivot joint, whereby first and second ends of the coil spring are coupled to the first and second elongate link members respectively; and a coil-spring-retaining-member slidable relative to the first elongate link member in a manner so as to vary a portion of a length of the coil spring engaged and retained by the coil-spring-retaining-member to vary an effective length of the coil spring.

Abstract: A cradle with a movable back supporting element. The back supporting element extends in one position to support the back of a portable device when the device is received by the cradle. The cradle also includes a supporting region which supports the end of the portable device. When the portable device is not in the cradle, the supporting element can be moved to a position in which it covers the end supporting region.

Abstract: A computer device comprises a casing in which are accommodated an electronic circuit and a touch screen, a protective cover movably arranged on the casing for selectively covering and uncovering at least the touch screen, and a stylus for operating said touch screen. The protective cover includes a compartment which substantially corresponds to the shape of at least part of the stylus and in which the stylus is removably stored, thereby reducing the size of the computer device for more convenient handling of the same by a user.

Abstract: An arrangement of a first receptacle and a second receptacle for separately receiving a card device in a portable computer. The first and second card receptacles are coupled to allow movement of the receptacles relative to each other between a first configuration where the receptacles are substantially nested, and a second configuration where the receptacles are substantially stacked, such that the receptacles move from the first configuration to the second configuration in order to receive a card device in the first receptacle.
