A locking device for a motor vehicle having a steering column has a blocking bolt that locks the steering wheel shaft in the steering wheel column, wherein the blocking bolt is movable between a first and a second position, a return element that returns the blocking bolt to the first position, and at least one protection cover that at least partially covers the return element. In the first position, the blocking bolt is in blocking engagement with the steering wheel shaft. In the second position, the blocking bolt is disengaged from the steering wheel shaft. The return element is a torsion spring. The torsion spring is a coil spring with a coil body and a connection hook. A first end portion of the torsion spring has a hook extension, and is inserted into an opening of the blocking bolt and is covered at least partially by the blocking bolt.

A luminous display includes pixels arranged in rows and columns. Control signals that are used for controlling first switches for measuring parameters of pixel cells in a first row are also used to control second switches for programming pixel cells in a second row. In this way it is possible to use a single control signal for selecting one pixel cell for programming and simultaneously selecting another pixel cell for measuring. Programming and measuring are thus performed in a time staggered manner, while the addressing is moved to the respective next row. The programming is preferably voltage programming. In one embodiment the current through the pixel cell that is currently programmed is interrupted. In another embodiment the measuring is performed only after the transient current into signal holding means coupled to current control means has set.

Luminous display and method for controlling the same

A driving circuit for a display with display elements in rows and/or columns has a shift register, through which tokens are shifted. The shift register's parallel outputs are latched and enable switch cells depending on the tokens. Control signals are supplied to the switch cells which control the output signal in terms of pulse width and/or signal shape. Buffers output the signals to a connected display. Individual or groups of buffers are connected to different supply voltages. The shift register may have more than one input in order to allow for shifting tokens in parallel, e.g. to every second output, using only one clock cycle. Further, inputs are provided for inverting the travelling direction of the tokens, inverting the shape of the signal that is output or switching all outputs to a predetermined state.

A circuit for an element of a light-emitting display is proposed. The element comprises a current control means, first and second switching means and a light-emitting means. In one embodiment, a signal holding means is provided. The arrangement of the first and second switching means of the element makes it possible to measure the electrical parameters of the current control means and of the light-emitting means during operation. A light-emitting display having a plurality of elements is furthermore proposed. The light-emitting display has a control circuit and a memory. The measured values of the electrical parameters of the current control means () and of the light-emitting means of the elements are used to correct the control signal S that is used to drive the elements. This enables a uniform brightness distribution in the case of voltage actuation and makes it possible to compensate for temporal changes in the light-emitting means. In addition, a method for actuating the elements and the light-emitting display is proposed.

Circuit and control method for a light-emitting display

In illuminated displays with lighting elements which are driven by means of a control voltage, the voltage drop on a supply line, which supplies two or more lighting elements, is compensated for. The currents for all of the light elements, which are connected to a supply line, and the known resistances are used to calculate the potential profile of the supply line for this purpose. The control voltages for the light elements are changed such that the actual potential on the supply line for each element is taken into account. Fluctuations in the brightness of the illuminated display resulting from potential differences are avoided. One element of an illuminated display has a current control means, a signal retaining means, a light emitting means and means for interrupting the current flow through the light emitting means. The control voltage is adjusted with the current flow interrupted, so that no potential differences exist on the supply line. The signal retaining means hold the control voltage relative to the potential on the line at the respective position of the lighting element. An illuminated display has adjustable voltages for the supply lines. The voltages are chosen to be sufficiently high that the minimum required voltage for setting the desired currents through the lighting elements is achieved.

An apparatus for generating a second signal having a clock based on a second clock from a first signal with a first clock comprises first and second means for sampling the first signal to determine whether the first signal has a predetermined logic state, wherein first means samples the first signal with the second clock, and second means samples the first signal with a clock phase shifted to the second clock. Means for generating the second signal generates the second signal based on the second clock if it has been determined by at least one means for sampling that the first signal has the predetermined state. Especially for time critical applications, such as a DDR-RAM, a valuable latency saving is provided by the present invention.

An output circuit (OUT) can be activated via an activation input (AKT), in the activated state starts an output process for data (D) to be read out, in synchronism with the first internal clock (CLKI), and outputs the data (D) with a specific phase shift (&#x394;TOUT) with respect to the first internal clock (CLKI), in synchronism with the external clock (CLKE), at a data connection (P). A counting unit (CT) starts a counting process for recording the number of successively following first levels of the first internal clock (CLKI) as soon as a second internal clock (CLKI), which is synchronized to the external clock (CLKE), for the first time assumes a first level while an output control signal (PAR) is at first level. It activates the output circuit (OUT) as soon as the number of successively following first levels of the first internal clock (CLKI) has reached a predetermined value.
