Abstract:
A multiplexer circuit includes switches 26 or 260 each having a hold portion 120 or 1200 and driving portion 110 or 1100 for providing a hold voltage or a select voltage to an output 14. If all control inputs 28A or 280A are at a first level, then the output has the select voltage, whereas if one input 28A is at a second level, the output has the hold voltage. The switches 26 may be integrated onto the substrate of a diode-based array of electrical elements, for example image sensing pixels. In this case, the output 14 includes a row conductor for a row of such pixels.
Abstract:
The invention relates to an electrical surface treatment device which is provided with an acoustic surface type detector with which a type of a surface to be treated can be detected during operation. According to the invention, the surface type detector delivers an output signal (u.sub.FT) during operation which is characteristic of the type of surface to be treated and which is determined by a value of a physical quantity of air vibrations reflected by the surface to be treated, which value is measured by a vibration detector of the surface type detector. In a special embodiment, the physical quantity is an amplitude, and the surface type detector is a vibration generator for generating air vibrations having a predetermined amplitude. The generated air vibrations preferably have a frequency of at least 15,000 Hz which varies within a predetermined range. In a further embodiment, the vibration generator generates the air vibrations intermittently, and the surface type detector is a parallel circuit through which a portion of the generated air vibrations can be directly guided to the vibration detector.
Abstract:
A VLIW processor has first and second functional units for executing first and second commands in a first instruction word. The first and second commands comprise a first field and a second field, respectively, in ordered concatenations of fields. The processor has a third functional unit for executing a third command in a second instruction word. The third command comprises both the first and second fields.
Abstract:
To control a converter of a satellite receiving system, the converter receives not only a dc voltage but one of two different voltages (normally 13 or 17 volt) also an alternating voltage (normally 22 kHz). It has to be possible to control more equipment along the same (coax) cable like amplifiers and switchers and to switch between more sub-bands than two. To achieve this the satellite receiver includes a power supply unit having switching apparatus which can combine the supplying of one of the two dc voltages with an alternating voltage continuous tone or burst as (switching) information.

Abstract:
A medical X-ray apparatus is provided with image detector elements 30 which are arranged in a matrix of rows and columns. In order to improve the noise behaviour of the read amplifiers 46 during the reading per row, a plurality of column conductors 36 is provided per column so that the read time is prolonged in proportion to the number of column conductors and the stray capacitance is reduced proportionally. Both steps reduce the noise in known manner. In the case of an integrated implementation, the conductors for driving the reading per row cannot be arranged arbitrarily close to one another because of their mutual capacitance, so that these conductors require a comparatively large surface area. In order to make a smaller surface area suffice for these conductors, according to the invention each read driver 42 is connected to at least two rows of image detector elements 30 which are not associated with the same column conductor, the number of rows thus connected to one read driver being at the most equal to the number of groups of image detector elements in one column.

Abstract:
A method and apparatus are provided for providing user-directed operation of a virtual manipulator, such as a simulated hand or claw (30) within a computer-generated virtual environment. The environment comprises one or more objects (32) which may be held, released or impelled by the manipulator under user control. Movement of the virtual manipulator is directed by a suitable hand held device operated by a user, with a simple control directing opening or closing of the claw (30). In operation, actions such as throwing, catching or punching an object (32) are partially automated, with the decision as to the action initiated being determined by the separation (D) between object and manipulator, and the current and previous states of each as recorded in the form of respective state variables. A method for the derivation of an applied velocity for the object acted upon is also described.
Abstract:
In Deformed Helix Ferro-electric liquid crystal display devices (DHFLCDs) the memory effect in video applications is interrupted by adapting the data voltages of matrix displays based on MIMs or TFTs, dependent on the data in a previous frame, so that the polarization within a cell always switches to a fixed value (zero). In other types of displays (based on diodes) or for less rapid applications, the polarization can also be readily set at this value.
