Abstract: The invention relates to an assembly of a capped high-pressure discharge lamp (1) and a lamp holder (50). The discharge lamp comprises an outer envelope (10) in which a discharge vessel (11) is arranged. The outer envelope has a pinched portion (20) provided with a clamping member (25). A lamp cap comprises a substantially circular-cylindrical cup shaped portion for receiving the clamping member and is provided with a protruding collar (36). The lamp holder (50) comprises a substantially circular-cylindrical flange (55) for receiving the cup-shaped portion such that the flange engages the protruding collar. An inner diameter of the flange (55) has a tolerance of less than or equal to ?0.2 mm. An outer diameter of the cup-shaped portion (33) has a tolerance of less than or equal to +0.2 mm. The respective tolerances extend over a length of at least 2.5 mm, measured with respect to the protruding collar.

Abstract: A device for holding a compact fluorescent lamp in a light fixture with a socket 10 and a lamp base is shown and described. The bayonet-type fixing of the lamp base in a socket 10 is effected by means of a plug-and-rotate motion. In order to give manufacturers of light fixtures the possibility of manufacturing light fixtures for lamps with a predetermined or maximally admissible lamp wattage, the invention proposes a key system with seven key pairs. Each key pair comprises a lamp key and a socket key and characterizes a predetermined lamp wattage. Concretely speaking, the socket key is a lug arranged in a hole and the lamp key is a plug corresponding to the socket hole with a outwardly open cutout. In addition, a key system for making predetermined lamp types recognizable is described.

Abstract: A printed circuit board having an upper face provided with contact traces and pads with a light-emitting diode fixed to the board and connected to the traces. A connector juxtaposed is with the pads and carries a contact element having a leg bearing with spring force on one of the pads and formations gripping a hookup wire. At least one fastener engages through the connector and circuit board with a heat-sink base and presses the connector against the circuit board and the circuit board against the base.

Abstract: A bipin fluorescent-lamp holder has a housing formed with an outwardly open housing mouth and a rotor rotatable in the housing adjacent the mouth about an axis and having a diametrally throughgoing rotor slot. The rotor is rotatable between an installation position with the rotor slot aligned with the slot and an angularly offset contact position with the slot not aligned with the mouth. The rotor and housing are so dimensioned as to receive the pins extending parallel to the axis and to move the pins in a circular orbit centered on the axis on rotation of the rotor in the housing, and contacts in the housing diametrally flanking the axis each having a main part lying outside the orbit and a contact part engageable into the orbit. The contacts pins are aligned with the slot and project into ends of the slot and into engagement with the pins only in the contact position of the rotor.

Abstract: The present invention relates to a method for subdividing the road pattern in digital road maps into segments, in which, starting from the digital road maps in which the road pattern is subdivided into successive segments, new segment borders are established via new segment starting points and segment end points, by selecting the segment starting points and the segment end points in such a way that the shape of the segments between the segment starting points and the segment end points does not change. The invention also relates to the computation of the road pattern with the aid of digital road maps, in which the road is subdivided into successive segments, to each of which one segment starting point and one segment end point is assigned.

Abstract: A lamp has a polygonal-section plug part extending along an axis and having at least one radially outwardly directed face formed with a radially outwardly projecting retaining bump. A socket has a core body formed with a polygonal-section socket hole complementary to the plug part and into which the plug part can be fitted axially in an installed position and that substantially completely prevents angular displacement of the plug part relative to the core body in the installed position. A sleeve surrounds the core body and can angularly shift relative thereto between a freeing end position and a blocking end position. The sleeve is formed with a radially inwardly projecting retaining formation that, in the installed position of the plug part, is angularly offset from the bump in the freeing position and that operatively engages and blocks axial displacement of the bump in the blocking position.

Abstract: The invention relates to a lamp comprising a lamp bulb (2) and a lamp base (3), which lamp base (3) comprises a projection (4) located in a substantially central position of the lamp base (3) and extending in a direction away from the lamp bulb (2), at least one lock-engaging portion (6), and a substantially flat base surface (5) opposed to the lamp bulb (2) and surrounding the projection (4), characterized in that the at least one lock-engaging portion (6) is located on the edge of the base surface (5) surrounding the projection (4) remote from the central projection.

Abstract: A socket for a bipin lamp has a relatively stationary body, a pair of contacts in the body symmetrically flanking an axis of the body, and a rotor formed with an axially open and generally diametrally extending slot and pivotal on the body about the axis between an outwardly open position and a crosswise position. Pins of the lamp are insertable into the slot and engageable with the contacts in the crosswise position. An operating part has a disk fixed to the rotor and formed with a slot aligned axially with the rotor slot and an arm fixed on and projecting radially from the disk past the lamp when the pins are in the slots. Thus a user can fit the lamp pins to the slots and pivot the rotor between the positions by the arm to engage the pins with the contacts.

Abstract: A method and system for updating clock references in a digital data stream is proposed, wherein all clock references present in the data stream are updated by means of a single system clock. A time recovery unit compares time tpcr transported in the clock reference (PCR) with the time of the system clock tclock and stamps the difference (tclock−tpcr) of the two times into the clock reference. After remultiplexing, a stamping unit reads out the time difference (tclock−tpcr) of the two times from the time stamp, subtracts it from the actual time in the system clock and stamps the value (tpcr+d) into the clock reference. Due to similarities in operation, the time recovery unit and stamping unit may share common circuitry.

Abstract: A fluorescent-lamp socket assembly has a socket, a standard base, and a starter base. The socket has a nonconductive housing having an open end and a pair of conductors in the housing engageable with contact pins of a lamp fitted to the housing and exposed in the open housing end. The standard base is shaped to fit complementarily into and close the open housing end and is formed with throughgoing holes through which wires can be engaged with the conductors. The starter base has a one-piece nonconductive housing having a plug end shaped to fit complementarily into and close the open housing end and an opposite end adapted to hold a starter and a conductor inside the starter-base housing for connecting a starter in the opposite end with one of the conductors in the socket.

Abstract: The process for transmission of images enables various classes of source-coded image data to be channel-coded and transmitted at various class code rates. For this purpose, source-coded image data to be transmitted are divided into classes of different sensitivity with respect to transmission errors and the classes are provided with different error protection and are channel-coded for transmission. Information words are provided at the beginning of each class containing information regarding the class type, code rate, number of data bits belonging to a particular class and regarding the error protection employed. In addition, a synchronizing word is added to the image data for each image. In the receiver the first information words are channel-decoded according to a fixed code rate and the information stored in the first information words including code rate is used for the channel-decoding of the received coded image data. The image data are subsequently subjected to an image source decoding and read out.
