  • Patent number: 6421547
    Abstract: An arrangment in a cellular mobile telephone apparatus includes a protective hatch or flip pivotably arranged on a housing of the apparatus. The flip is pivotable around an axial compartment in the housing and is arranged to physically cover at least part of a front side of the housing. The axial compartment includes a hinge which provides a mechanical connection between the flip and the housing and permits an electrical connection between the microphone and the printed circuit board of the telephone. The electrical connection between the microphone and a printed circuit board in the telephone housing includes a first wiring that leads from the microphone to a first contact. This first contact is fixedly arranged in the ear of the flip. A second contact rotatable in a hole in the axial compartment is connected to a second wiring that leads from the second contact to the printed circuit board of the telephone.

  • Publication number: 20020052209
    Abstract: A portable radio communications device (1) has a display (6) on which a position indicator (7) can be positioned, and means (8) for controlling the position of the position indicator (7) on the display (6) manually by a user. The controlling means comprise an optical emitter adapted to illuminate an object through a translucent and moisture-proof surface; an optical detector adapted to detect changes in light reflected from the object due to the movement thereof; and circuitry for generating a control signal for the position of the position indicator (7) in dependence on the changes in reflected light. The optical detection of the movement of a finger provides a very easily operated control device with no need to press the finger against the device, and thus forces on the printed circuit boards are avoided. The moisture-proof surface ensures that the device is insensitive to dirt and moisture.
