Relief object image generator

A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device, which may be inorganic or organic, and a current source. The current source is coupled to the single electrode of the electroluminescent device and to the relief object to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device to generate light at different intensities that correspond to the ridges and valleys of the relief object. The generated light forms an image of the relief object which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device to capture the image. In an embodiment of the invention which insulates the relief object from current, the electroluminescent device is covered with a variable resistance layer and the variable resistance layer is covered with a flexible electrode. One lead from the current source is coupled to the flexible electrode and another lead is coupled to the single electrode. When a relief object is brought in contact with the flexible electrode, a localized pressures generated by the ridges of the relief object form conductive paths through the variable resistance layer which are lower in electrical resistance than those formed by pressure in the areas adjacent the valleys of the relief object. The different magnitudes of current delivered through the conductive paths to the electroluminescent device cause the electroluminescent device to generate an image of the relief object without exposing the relief object to electrical current.

Loop antenna with a parasitic radiator

ActiveUS20070182658A1Radiation efficiency be lowBoost performanceAntenna arraysSimultaneous aerial operationsRadio frequencyFrequency band
It is an objective of the present invention to provide an antenna construction that allows the thickness of an antenna structure be lower than that of planar antennas according to prior art without sacrificing the radiation efficiency at the desired RF-bands as 900 MHz GSM and 1800 MHz / 1900 MHz DCS / PCS. A further object of the invention is to provide an antenna construction that is insensitive to changes in positions of electrically conductive objects in the vicinity. The objectives of the invention are achieved by a loop antenna structure equipped with an electrically conductive parasitic radiator that is electro-magnetically coupled with the antenna loop. Performance at the DCS / PCS bands can be further improved by using an electrically conductive tuner element that provides a stronger electromagnetic coupling between the antenna loop and the parasitic radiator.

Contacting device for a chip card and in particular for a SIM card

There is provided a contacting device (1) for chip cards, preferably for SIM cards, comprising a base (2), a slider (12) arranged at the base (2) and being movable with respect to the base (2), the chip card (4) being slidable between an insert / removal position and a reading position by means of said slider, and means (7, 22) for inhibiting removal of the slider from the contacting device (1). Preferably, the slider (12) is slidably mounted to the base (2) and is in abutting engagement with an abutment in the insert / removal position such that the slider (12) cannot be removed from the contacting device (1), i.e. the slider (12) cannot be moved beyond the insert / removal position. Thus, the contacting device does not comprise any loose parts that could get lost. In accordance with another embodiment of the present invention, there is provided a contacting device (1) for a chip card (4) comprising a stationary base (2) and a movable slider (12), wherein a chip card (4) is slidable between an insert / removal position and a reading position, wherein a metal cover (24) is fixedly mounted to the contacting device (1) and for providing support for the chip card (4) for providing counter-forces taking up contacting forces between contacting elements of the contacting device (1) and contacting pads of the chip card. Preferably, the contacting device (1) has a card plenum (11) for receiving the chip card (4), and the metal cover (24) spans the card plenum (11) as well as the slider (12) and extends around the sides of the base (2). By using a metal cover, a particularly small thickness is possible for this component. Further, the metal cover is easy to manufacture and to assemble.
