Abstract: Arrangement for the controlled manual selection of an image and/or the adjustment of the display parameters thereof to be shown on a display (13, 22) of a smart electronic device that comprises a handling field (2, 25, 32, 41) controlled by the touch of a finger, wherein a first predetermined group of image and/or display parameters can be controlled by a finger of a user, and the arrangement comprises a further handling field (1, 27, 37, 38, 42) arranged in a position that can be touched by a different finger of the same user and by being touched at least one further display parameter can be adjusted that does not belong to the first group, and the further handling field (1, 27, 37, 38, 42) is arranged spaced from said handling field (2, 25, 32, 41) and the handling fields are mechanically connected through a common body (11, 24, 31).

Abstract: A data entry device for entering predetermined characters by the finger of a user and converting the characters into a sequence of electronic signals representing the entered characters, that comprises a touch sensitive zone (2) on an outer surface, a processor (58) coupled to the touch sensitive zone (2) for sensing the zone (2) is touched, the processor (58) is programmed to recognize predetermined elementary finger movements and combinations thereof and to associate each of them with a character, wherein a closed boundary (10) is defined on the surface of the device above a portion of the touch sensitive zone (2) that has at least one haptic property differing from the haptic properties of the surrounding area, whereby the finger can definitely sense when the boundary (10) is touched, and the boundary (10) has an interior area constituting a data entry field (11) that has a centre region (16) which has at least one haptic property differing from the haptic properties of the portion beyond the centre region

Abstract: Method for the conversion of elementary finger movements and/or movement combinations of a user into respective characters and/or functions presented as electrical signals by using a hand held smart electronic including the steps of: —associating a group of the movements and movement combinations with respective ones of characters and/or functions prior to the beginning of the conversion step so that the movements take place in a region defined by a closed boundary line; —in the associating step defining a predetermined number of special positions along the boundary line of the permitted region of movement; —entering the required characters and/or functions in a consecutive sequence further including the steps of: —holding the device in a hand so that a free finger touches an upper surface thereof; —moving the finger according to the movements or movement combinations associated with the character or function to be entered; —providing haptic feedback to the user when the boundary line and any of the special p

Abstract: An instrument for measuring positions and displacements of portions of a human body, comprising a base plate and a belt or suction cup for detachably securing the base plate to a portion of a human body. A bifurcated holder is mounted on the base plate for rotation about a first axis, the bifurcated holder having a pair of arms, and a housing is pivotally carried between these arms for swinging movement about a second axis perpendicular to the first axis. A dip circle and a north-south-seeking compass are carried by this housing, the dip circle and compass being mounted on the housing for pivotal movement about a common third axis perpendicular to the second axis. The base plate has a scale thereon, and there is an indicator on the holder for indicating on the scale the degree of rotation of the holder relative to the base plate.
