  • Patent number: 6635991
    Abstract: The invention relates to a method of adjusting a desired spectrum of light emitted by a gas discharge lamp during its operation, said gas discharge lamp comprising a first ionizable substance and a second substance which is less readily ionizable than the first substance. According to the invention, the gas discharge lamp is operated such that gases of both substances cans be excited, while the partial pressure of the first substance is adjusted in dependence on the desired spectrum. For this purpose, for example, the current through the lamp may be modulated. In an alternative embodiment, this is suitably achieved in that the partial mercury pressure is varied, for example through an adjustment of the temperature of a mercury amalgam present in the gas discharge lamp. The invention also relates to a gas discharge lamp whose color can be varied during its operation, and to a luminaire provided with a supply for such a lamp.

  • Publication number: 20030155821
    Abstract: A positioning device comprising a first part (1) which is movable relatively to a second part (2) in an X-direction and a Y-direction, said first part (1) comprising a carrier (5) on which a system of magnets (3) is arranged according to a pattern of rows (7) and columns (8) extending parallel to the X-direction and the Y-direction, respectively. The magnets in each row and column are arranged according to a Halbach array, i.e. the magnetic orientation of successive magnets in each row (7) and each column (8) rotates 90° counterclockwise. The second part (2) comprises an electric coil system (4) with two types of electric coils (C1, C2), one type having an angular offset of +45°, and the other type having an offset of −45° with respect to the X-direction. The magnet configuration causes a very strong magnetic field.

  • Publication number: 20030134609
    Abstract: In a receiver, a frequency-synthesis circuit (SYNTH) generates a stepped-frequency signal (Ssf) having a frequency which can be varied in steps. A synchronization circuit (LOOP) synchronizes a tuning oscillator (LO) with the stepped-frequency signal (Ssf). It provides an integer frequency-relationship between the stepped-frequency signal (Ssf) and the tuning oscillator (LO). That is, if the stepped-frequency signal (Ssf) has a frequency Fsf, the tuning oscillator (LO) will operate at a frequency Flo=N·Fsf, N being an integer or an integer fraction.

  • Publication number: 20030123557
    Abstract: An encoding circuit transforms a picture signal into blocks of, for example, 8*8 coefficients, in which each block of coefficients is read motion- adaptively. In the case of motion within a sub-picture, the block of coefficients is read in such an order that the obtained series of coefficients includes, as it were, two interleaved sub-series. The first series starts with a dc component. In a first embodiment, the second series starts with the most relevant motion coefficient. In a second embodiment, two interlaced sub-fields are separately transformed and the second series also starts with a dc coefficient. As a result, the coefficients are transmitted as much as possible in their order of significance. This particularly produces the largest possible clusters of zero value coefficients. Such clusters are transmitted as one compact run-length code so that an effective bit rate reduction is achieved, also for moving pictures.

  • Publication number: 20030122655
    Abstract: Short range communication systems and techniques are described. In an implementation an interrogator held near a person interrogates multiple transponders and receives information separately from the transponders. The interrogator and/or the transponders may be held in an article of clothing or in a personal effect of the person. The transponders may transmit identifying information and/or information associated with the states of the articles of clothing or personal effects of the person. Such a system enables the clothes worn by a person to communicate with a plurality of items and obtain useful information. In addition, a network system may be configured so that any particular transponder may communicate with another transponder or group of transponders of other locales to activate functions, cause actions or otherwise share data and/or information.

  • Publication number: 20030087027
    Abstract: Method and device for providing a layer (6) of a coating material on the inner side (2) of a display window (1) for a color display tube. A drop (3) of a suspension of said coating material is deposited on the inner side of the display window, its axis of symmetry (4) being oriented vertically. Then the display window is rotated around said axis of symmetry, and at the same time, said axis is tilted to a horizontal position. The suspension is thereby distributed on the inner side of the display window. An excess of suspension is collected during the rotation in four collection cups (8) arranged at the corners (7) of the display window, whence it is drained off to a central collection cup (10). Finally, the part of the suspension which remains on the display window is dried by infrared radiation (9).

  • Publication number: 20030067786
    Abstract: A headlamp (2; 3) of a vehicle (1) has a light source (4; 5) comprising a plurality of opto-electronic elements (11; 12; 13; 14), preferably light-emitting diodes (LED's). At least one of these opto-electronic elements (11; 12; 13; 14) has, in operation, a luminous flux of 5 lm or higher. According to the invention, the spectral characteristic of the light beam (6, 6′; 7, 7′) generated by the light source (4; 5) depends upon the position in the light beam (6, 6′; 7, 7′). Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. The light beam comprises at least two light beam segments (6, 6′; 7, 7′) having essentially different spectral characteristics. Preferably, one of the light beam segments (6′; 7′) is mesotopically tuned.

  • Publication number: 20030031255
    Abstract: The invention relates to a video coding method based on an adaptive frame/field encoding mode. In order to avoid an impairment of the image quality and of the compression efficiency when a video sequence comprises a lot of motion or on the contrary quasi-motionless images, an improved real time double pass encoding scheme is proposed: during the first pass, no video stream is generated, but statistical results are computed and then provided to the second pass in order to optimize during said second pass the bit rate allocation and the buffer management. This improved double pass encoding method leads to an increase of the compression efficiency of about 10%.
