With a view to bringing the cursor into a zone of the image displayed on a screen, the method embodying the invention uses a displacement mode comprising determination and indication on the screen of the orientation and relative direction of displacement one wishes to obtain, this stage being performed by varying the orientation of the index (C) by a first manual command until the required direction is obtained; relative displacement of the cursor (C) in relation to the image, in accordance with the orientation and direction thus determined until it reaches said zone, this displacement being performed by a second command distinct from the first; and validation of the position occupied by the cursor in relation to the image by a third command distinct from the first two. The invention relates equally to conventional management of a cursor, the plotting of the route of an aircraft or even to multidirectional scrolling of an image on a screen.

Method and device for managing the relative displacement of a cursor in

The management device embodying the invention uses a control source consisting in a touch-sensitive work board comprising a touch-sensitive surface and a means enabling detection of a force on said surface. It further comprises a selection means enabling switching from the relative pointing mode to the absolute pointing mode depending on whether the force exerted exceeds or is less than a predetermined threshold value. The invention enables the advantages of the two pointing modes to be accumulated.

The multichannel coder embodying the invention comprises a knob coupled with a code wheel associated with a means for detecting the angular position and, possibly, the direction of rotation of the wheel. It comprises, on the one hand, a channel selection means incorporated into the knob, and, on the other hand, a means enabling the association, with the information provided by the detection means, of information relating to the channel that has been selected on the aforesaid selection means. The invention can be used to modify parameters.

Multichannel coder of single-channel structure

The compact and ergonomic communications terminal equipped with proximity detection surfaces embodying the invention comprises a screen and command device distributed around the periphery of the screen, the command device comprising two devices for detection on a respective axis of the position of an operator's finger, divided into a plurality of segments assimilable with switch operating keys, the axes of these two detection devices being perpendicular to one another and each disposed facing an edge of the screen. It is notably used inside the cockpit of an aircraft.

The manipulator embodying the invention comprises a disk mounted rotatably about an axis by a shaft and capable of pivoting about a center of rotation with elastic return motion towards a home position, a detector which determines the angular position of the disk in relation of the axis, strain gauges detecting the orientation of the disk with respect to the center of rotation, a reversing switch for switching from an operating mode in which the data relating to the orientation of the shaft are taken into account, to an operating mode in which the data ralating to the angular position of the disk are taken into account, and a switch for validating one or other of these data. The invention applies notably to the remote control of a cursor on a screen.

Multimode manipulator

The device for clearance-free mounting of panes of glass embodying the invention comprises blocks each having a through passage of oblong section in which can freely pass a fastening screw intended to be screwed into a threaded bore of the support of a pane of glass, the blocks also having an oblique face susceptible of sliding and self-adjusting against an edge of the pane of glass. The invention notably enables a protective pane of glass to be fixed to a viewing screen.

A switch device with two modes of operation includes at least one switch comprising, carried by a substrate, two conductive lands and an electrically conductive elastic capsule in contact with one land and, in the unoperated condition, overlying the other land so as to be capable of being urged into contact with the latter. An electrical signal from a source is applied to the capsule. A circuit measures variations of the signal due to the proximity of an electrically conductive object. The device can be used to implement matrix keyboards combining the functions of a conventional keypad and a tactile pad.
