  • Patent number: 9140843
    Abstract: An apparatus includes a light guide. A first light input section receives light in a first direction into said light guide. First direction-dependent outcoupling structures selectively couple out light propagating in said first direction in said light guide. A second light input section receives light in a second direction into said light guide. Said second direction is different than said first direction. Second direction-dependent outcoupling structures selectively couple out light propagating in said second direction in said light guide.

  • Publication number: 20090140989
    Abstract: The invention relates to a user interface for controlling an electronic device. The user interface includes a sensor element that has a sensor surface and is arranged to form a location indicator that indicates a location of a spot of the sensor surface that is closest to an external object. A force sensor is arranged to form a force indicator that indicates strength of a force directed to the sensor surface. A processor unit is arranged to control the electronic device on the basis of the location indicator and the force indicator. A user of the electronic device is enabled to control the electronic device by using different levels of the force directed to the sensor surface. Therefore, the electronic device can be controlled with a smaller number of repetitive pressing and release actions.

  • Patent number: 7466994
    Abstract: The invention relates to a mobile device, which comprises a first housing and a second housing, which housings are arranged movable in relation to each other to at least a first and a second position; the first housing comprising a primary display for displaying information and arranged to be visible for a user at least in the first position; the device further comprising a passive image steering element that is adapted to steer at least a part of the view of said primary display to become visible for the user as a secondary display in the second position. This invention also relates to a image steering module, a method in a mobile device and a computer program for controlling a user interface of a device.

  • Patent number: 7200009
    Abstract: It is an object of the invention to provide a electromechanical structure comprising an input device and a printed wired board (3, 4), which structure is advantageous in terms of manufacturing and offers freedom to the layout design of the printed wired board, the user interface as well as the appearance of the device itself. It is also an object of the invention to provide a electromechanical structure that is compact and facilitates the customizability and upgradability with a new electronic functionality without any need for modifications to the main electronics of the device. This is achieved by integrating the electromechanical assembly with the mechanical cover part of the electronic device by using an injection moulding process to compose an integrated combination (113) which is detachable from the electronic device. More precisely the objects of the invention are achieved by combining the injection mould technologies with the printing of electronic wired boards.

  • Publication number: 20060238505
    Abstract: The invention relates to a control device for browsing and selecting an item in a list. Especially the invention relates to a joystick type control device to be used in portable electronic devices, such as mobile phones and laptops. The control device comprises a stick means, which is coupled with a joint to the control device. Further the control device comprises at least one switch and at least one sensor, where the switch is adapted to make contact and generate a digital-type output signal when the stick means is deflected from its rest position in a direction. The sensor is adapted to generate an analog output signal when the stick means is deflected in from its rest position to a direction.

  • Patent number: 7035088
    Abstract: A pop-up electronic device has a keypad and display module arranged for slideable engagement with an outer cover wherein the keys of the keypad are nested within the outer cover in the device fully closed position and are exposed in the device fully open position. A protective window is in an overlapping relationship with the display in the device fully closed position and non-overlapping relationship with the display in the device fully open position to allow contact with and direct viewing of the display screen surface. The keypad and display module and protective window are mechanically arranged such that movement of the protective window in one direction causes the module to move in an opposite direction to change the electronic device between device fully open and fully closed positions.

  • Patent number: 6710950
    Abstract: A support for an optical system of a digital camera is constructed which provides adjustable positioning of the lens elements in response to signals from the camera control processor. The support comprises multiple tubes, mounted for relative coaxial movement, which support a lens element. At least one of the tubes is adjustable in position relative to a main support tube. The adjustable tube is engageable by piezoelectric elements. Each piezoelectrical element is mounted to a flexible printed circuit board which contains the camera operating system and is mounted on the support tube.
