Abstract: Even if an output voltage from a high-voltage power source includes a ripple, this invention reduces the influence on a luminance output and suppresses the capacitances of a high-voltage power source transformer and smoothing capacitor. An electron-beam apparatus adopts line-sequential driving of allowing a plurality of electron-emitting devices to simultaneously emit electrons in an arrangement in which an accelerating potential for accelerating electrons includes a ripple. At the same time, sets of devices allowed to simultaneously emit electrons are sequentially switched. The frequency of the ripple is synchronized with the selection frequency of line-sequential driving.

Abstract: The invention relates to an antenna unit for receiving electromagnetic signals in a vehicle, comprising a plurality of antennae, of which at least one antenna is adapted to receive signals in the GHz range and at least one antenna has an essentially two-dimensional spatial extent, and two or more tuner units, which are each connected to at least one antenna. The antenna unit is characterized in that the output signals from the tuner units are connected to a common coordinating member, and that said antennae, tuner units and coordinating member are arranged on a common supporting element to form an integrated unit. An output signal from the coordinating member is via a communication interface connectable to a vehicle-internal communication path. Antennae and tuner units can be releasably arranged on the supporting element to provide a modularized antenna unit.

Abstract: A method and system of modifying one feature of a high-pressure lamp without significantly affecting the other features, the features including the luminosity, the color rendering index, the color temperature, or the deviation from the black body locus (DUV). An arc discharge is initiated within the arc tube with a ballast imposing an alternating current waveform on the electrodes. In this way, the electrodes change from positive to negative in each cycle of operation. The waveform of each cycle is modified through the ballast to energize one electrode as positive or negative for a longer time than the other electrode, thereby altering the temperature distribution within the arc tube by changing the cold spot and hot spot temperatures in a lamp which has modifiable emission features.

Abstract: A first and a second conductive patch of a compact cylindrical microstrip antenna are connected at a junction point to shorten the length of the impedance transition from one edge, where the wave impedance vanishes, to the other patch edge, where the impedance becomes very large. The second conductive patch is wider than the first conductive patch and one end of the first conductive patch is shorted with the ground plane. The effective impedance to be satisfied by the narrower strip at the junction is greatly reduced by the presence of the junction of two different patches, which substantially decreases the size of the antenna at a given operation frequency.

Abstract: An antenna system for a satellite-supported navigation device in a vehicle includes a part which is to be arranged on the exterior of a mounting surface of the vehicle body and which contains an antenna component, a system part to be arranged on the interior, and a coupling device for coupling on antenna signal and a power supply between the exterior part and the interior part. The coupling devices includes signal transmission devices which transmit power supply signals and, as required, also data signals in a wireless manner through the mounting surface between the exterior and the interior parts.

Abstract: Apparatus is provided for coupling to a hand-held transceiver such as a cellular phone that is being operated in a radio frequency-shielded environment such as in an automobile, to transfer energy between the transceiver and an auxiliary antenna that is not shielded from the surroundings. The apparatus includes a pair of capacitor coupling elements (30, 32) that are positioned adjacent to each of the two radiating elements (40, 54) of the hand-held transceiver, and a coaxial cable (20) that connects the coupling elements to the auxiliary antenna. Each coupling element includes a sheet of electrically conductive material lying adjacent to a corresponding radiating element of the transceiver without surrounding the transceiver.

Abstract: At the onset of ageing or in the further course of their service life, color picture tubes relatively frequently exhibit a rise in the field strength between the cathode (K) and the Wehnelt electrode (G1) of the respective beam system on account of a blooming effect of the cathodes (K) which is known per se and reduces the spacing between cathode (K) and Wehnelt electrode (G1). The cut-off regulation reacts to an effect of this type in a manner such that the reverse voltage acting between cathode (K) and Wehnelt electrode (G1) is correspondingly reduced in order to be able to drive the same reference cathode current. However, the reaction of the cut-off regulation must be taken into account for the circuit design since this would otherwise result in an unacceptable reduction in the modulation range, which would, in turn, have an adverse effect on the maximum contrast setting.

Abstract: A system for promoting passive end of life light source failure in response to thermal cycling of the light source includes an automatic relay in communication with a ballast or groups thereof for interrupting power to the associated light sources. Alternatively, the relay may be configured to short out the light source directly. The automatic relays are configured to turn off associated light sources at predetermined or random times for predetermined or random durations.
