Abstract: A physical random number generator has a bi-stable latch that operates to generate a random number bit in response to a reception of one or more voltage input signals and a clock signal. A voltage source provides the voltage input signal(s) for provoking the bi-stable latch into a metastable state. A clock provides the clock signal for triggering the bi-stable latch. When triggered, the bi-stable latch latches the random number bit as a function of its metastable state provoked by the voltage input signal(s).

Abstract: The circuit arrangement serves for the voltage supply of the row and column drivers of a liquid crystal display device. It comprises a voltage divider (1) having a plurality of series-connected resistors (R1–R5) and having voltage pick-offs (22–25) arranged between the resistors (R1–R5) for picking off different voltage levels (V2–V5). A single one (25) of the voltage pick-offs (22–25) is provided with means (3) for fine-tuning of the voltage level (V5) picked off there. By individually calibrating each individual circuit arrangement once, the one voltage level (V5) may be fine-tuned such that crosstalk caused by asymmetrical voltage levels, i.e. mutual interaction of pixel contents, is reduced. The advantages of the circuit arrangement come into their own in particular when it is used in liquid crystal display devices with a gray-stage display or color display.

Abstract: A side-lit illumination arrangement comprises a polarized-light-emitting waveguide comprising a polarization-selective beam-splitting interface formed at an interface of a waveguiding layer and a polarization-selection layer. In order to avoid alignment problems occurring during the manufacture of the waveguide which impair the proper functioning of the polarization-selective beam-splitting interface, the polarization-selective beam-splitting interface is planar. Waveguided light polarized and transmitted by the polarization-selective beam-splitting interface into the polarization-selection layer is coupled out by a relief-structured surface via an exit surface. Display devices having such waveguides, in particular if used in a front light, have a high brightness and efficiency.

Abstract: The invention relates to a system and method for vibration isolation and cancellation, especially but not exclusively suited for a damper in wafer-chip production equipment. Active vibration isolation and cancellation technology (or air mount technology) for chip production equipment needs to become more effective with the advancement of the production of chips that require ever-smaller features. Typically, actuators and sensors in an active isolation/cancellation system are frequently used but not optimized in their technology. By integrating the actuators and the sensors together certain performance limitations become negligible and can be discarded. The resulting damper can be of an absolute or of a relative damper type. The performance of a vibration isolation and cancellation system and its limitations can be described using gain and phase relations from the control theory. A damper that uses the proposed system is of a so-called absolute damper type.
