A small and cheap user's input device for measuring scroll-and-click movements of a finger () or other object relative to the device comprises at least one sensor unit () and sensor signal analyzing means () to derive click information and scroll information from the same sensor signal. The analyzing means is designed such as to recognize a first typical time pattern of a click action and a second typical time pattern of a scroll action. Moreover in analyzing a sensor signal obtained during a time interval data obtained during other time intervals can be used to supply reliable signals. This device can be used in a number of different consumer apparatus, such as a mobile phone ().

Method of measuring the movement of an input device

A method of and an input device for measuring scroll or click movement of an object and the input device relative to each other, includes determining the presence of the object on a window of the input device. Lower frequencies of an output signal from single sensor unit are separated and used for determining both the scroll and click motions. This allows measuring scroll movement and click movement with one sensor unit of the input device and reduction of costs and size of the input device.

A waveguide comprises a longitudinal first conductor () located in an inner space of a box-shaped longitudinal shield conductor which is provided with a slot () defining a sliding support for a substantially plate-shaped coupler (). The shield conductor () is provided with flanges () extending substantially parallel to each other on opposite sides of the slot (). A coupling conductor portion () faces the first conductor ().

Waveguide communication system

An optical input device for measuring the movement of a finger () ia accommodated in a housing provided with a transparent window () for transmitting a measurement beam () from a diode laser () to the finger and radiation reflected by the finger to a detector (). This feature prevents that grease and dust disturb and block the measuring beam.

The invention relates to a device having touch sensitivity functionality, comprising a surface ( ), touch-sensitive means ( ) for detecting the presence of a touch input member ( ) being in contact with or close to the surface ( ) generating a distance sensor signal. Since conventional resistive or capacitive touch-sensitive layers have a limited transparency, they significantly reduce the screen quality. According to the invention, a display device having touch sensitivity functionality is provided without adding a layer to the display, and is characterized in that the touch-sensitive means ( ) comprises means ( ) for emitting a laser beam ( ) in a plane parallel and close to the surface ( ), said laser beam being periodically deflected across the entire surface ( ), and means ( ) for receiving the light reflected or scattered from the touch input member ( ) generating said distance sensor signal therefrom.

Measurements on a sheet ( ), for example measurement of the movement of the sheet in a printer, can be performed by directing a measuring beam ( ) towards the sheet and utilizing the effects of self-mixing in a diode laser ( ) and Doppler shift in the measuring beam caused by the movement. The measuring method and a dedicated, cheap and compact, sheet sensor ( ) may be used for determining different parameters and in different sheet processing apparatus.

Method of measuring the movement of a material sheet and optical sensor for performing the method

An optical input device for an apparatus generates input signals by moving the device and an object ( ) relative to each other and measures the movement by the effects of self-mixing in a diode laser ( ) and Doppler shift caused by the movement. For each measuring axis (X, Y, Z), radiation from a diode laser ( ) is converged on a window ( ) across which the object ( ) moves. Part of the radiation scattered by the object, whose frequency is Doppler-shifted due to the movement, re-enters the laser cavity ( ) and causes a change in cavity properties. By measuring such a change, for example, by a photo diode, information about the movement is obtained. As the input device is small and cheap, it can be used in a number of different consumer apparatus.
