    摘要: Device for selecting values of data elements forming part of a group of data elements includes an operation circuit, a display unit and first register for registering and delivering values of data elements to the display unit. The operating circuit, depending upon the time such circuit is activated, causes the selection of a value of a data element. A second register is provided for registering and delivering to the first register and to the display unit indication information controlling which one of the data elements out of the group of data elements is to be selected. A third register is also included to alter the indication information on a repeated activation of the operation circuit so that subsequent data elements out of the group of data elements are prepared for value selection. Other embodiments of the device includes a plurality of separate operation circuits, of separate operation circuits, an erase feature and implementation with a programmable digital signal processor.

    摘要: In a method for testing mass-produced articles a test cycle is run during transport of said articles from a first predetermined position to a second predetermined position. During said transport the articles are provided with a connection to an electric mains for supplying the article with operational power, with a control means for controlling the article through a predetermined series of program steps for simulating a cycle of operational use, sensing means for sensing an operational condition of said article and storing means for indiscriminately storing output signals of said sensing means. Upon arrival at said second predetermined position said storing means is connected to a data processing means, whereby the signals stored therein are processed for rendering an indication concerning the performance of the article. For obviating the need for installing specific sensor elements within the article a principle quantity measured is the level and variation of the input current consumed by the article under test (at a constant mains voltage) during the execution of the successive program steps. If the mains voltage is variable in time, the variation is properly corrected for during the measurements.

    摘要: In a receiver of a transmission system for binary pulse signals whose DC level is disturbed during transmission, an accurate correction of the disturbing DC components is obtained even for pulse signals deviating considerably from the nominal transmission speeds and peak values, by using a correction circuit having two parallel branches between input and output. The first branch includes a capacitor between input and output and the second branch includes a peak detector and a comparator which co-operate for generating a binary decision signal which is applied to the output via a resistor. The AC components of the pulse signals are only passed through the first branch and the DC components inherent in the pulse signals are only passed through the second branch.
