Abstract: The invention relates to an antenna comprising a dielectric substrate ( 1 ) and two resonant printed wiring structures, more particularly for use in high-frequency and microwave domain. On an end face of the structure ( 2 ) is arranged along a first edge and on an opposite, second edge of the same end face a second printed wiring structure ( 3 ). The arrangement of the printed wiring structures provides that resonances are developed which make the use of the proposed antennas in the four separate GPS, DCS/PCS, UMTS and Bluetooth applications possible.

Abstract: Active display (1, 1') has a display surface with active pixels (3), whereby each pixel is assigned to a local control unit (4). Each control unit controls the light emitted by the pixel according to information it receives in a signaling beam (I) that is transmitted from a projector (2). The signaling beam containing information relating to brightness and color. The invention also relates to a corresponding projection device and a method for presentation of an image of a projection surface. According to the method an infrared or ultraviolet beam is used to transfer digitally encoded data from the projector to the pixel control units.

Abstract: A microwave antenna is described, having a substrate ( 11 ), at least one resonant metallization structure ( 1 ) and at least a first and a second feed point ( 3, 4, 6, 7 ) for coupling in HF power to be radiated, said antenna being particularly suitable for surface mounting on a printed circuit board ( 20 ). The feed points ( 3, 4, 6, 7 ) are so arranged in this case that, for different positions of the antenna ( 10 ) on a printed circuit board ( 20 ), it is in each case possible to select a feed point in which case the electrical properties of the antenna ( 10 ) are at least substantially unchanged.

Abstract: The present invention relates to a light sensor device comprising a substrate (18), a first light sensitive area (14, 15), and a second light sensitive area (12, 13). It is characterized in that a first optical filter device (22) assigned to said first area (14) and adapted to filter the visible light spectrum and a second optical filter device (24) assigned to said second area (12) and adapted to filter the non-visible light spectrum, preferably IR light spectrum, are provided, and said first and second light sensitive areas (12, 14) are fabricated on the same substrate (18) adjacent to each other to form a single integrated sensor component (10). The invention also relates to a lamp device (60) comprising such a light sensor device.

Abstract: A circuit arrangement for operating a lamp comprising input terminals for connection to a supply voltage source. A DC-AC converter is coupled to said input terminals for generating a high frequency signal. A piezoelectric transformer having a primary side that is coupled to the DC-AC converter and a secondary side that is coupled to terminals for lamp connection and a dimming circuit for adjusting the light output of the lamp. The DC-AC converter generates a substantially square wave shaped signal and the dimming circuit is coupled to the DC-AC converter for adjusting the lamp light output by adjusting the duty cycle of the substantially square wave shaped signal. A lamp operated by the circuit arrangement is dimmable over a wide range while the amount of power dissipated in the circuit arrangement is relatively low, even when the lamp is dimmed.

Abstract: Microwave antennas with a dielectric substrate ( 1 ) and at least one resonant conductor track structure ( 31 to 39 ) are described, which are particularly suitable for mobile dual-band and multiband telecommunication devices such as mobile and cellular telephones, as well as for devices which communicate in accordance with the Bluetooth standard. In addition, attuning of the resonance frequencies of various operating modes to a concrete constructional situation is possible thanks to various line segments ( 34, 35 ) and tuning stub lines ( 41, 42 ) without the necessity of changing the fundamental antenna design. Finally, the antennas may be soldered together with other components onto a printed circuit board in a conventional surface mounting process.

Abstract: The surface metallising is formed by a feed (12) for electromagnetic energy to be emitted, at least one metallising structure (30) and a conductive track (20) extending along the substrate (10) periphery and coupling the feed to the metallising structure. The metallising structure contains a first conductive track section (31), extending at the substrate side, opposite to the feed, up to the feed, as well as a first metallising platelet (32). The metallising structure is located on one front face of the rectangular substrate. Independent claims are included for a printed circuit board and mobile telephone.
