    To achieve high speed for field-manipulation operations, current microprocessors employ high speed arithmetic logic units having circular shift and masking capabilities. Such architecture provides very efficient systems code, and device controller and emulator microcode. A differential cascode mask and merge unit in...

    A redundancy scheme and a new circuit design are described which comprise an enhanced yield memory with no loss of access time. The figure shows in particular a new address true-complement (T/C) switch which provides the memory with a distinctive feature so that a thin-oxide capacitance during the normal operation of...

    This article describes a smart card which is acoustically coupled to an associated terminal. The acoustic coupling provides power to the card and a mechanism for transferring data to or from the card. Referring to the drawing, a terminal 10 includes logic circuits 12 coupled to a piezoelectric laminate (PL) 14...

    In packaging any electrical or electro-mechanical assemblies, the internal cables normally are a high-cost, low-reliability area. In a cash drawer assembly, it has been found that the use of a printed circuit card in place of internal cables decreases costs and increases reliability. In Fig. 1, the printed circuit...

    As a storage location with several hard failures cannot be used, it is known to use a replacement location instead. In a directory, the addresses of all faulty storage locations are stored, and the storage address applied to the memory is compared with all addresses contained in the directory. In response to a...

    Described herein is a magneto-optic disk read/write head featuring an electromagnetic coil for writing which is located at the tip of the optical mount adjacent the focus point for the optics of the head. This configuration allows a rapid or high frequency switching of the field produced by the coil. This in turn...

    The rapid development of VLSI (very large-scale integration) and VHSIC (very high-speed integrated circuit) technology and design, which led to higher complexity, submicron size and very short switching times (10 - 20 ps), necessitates contactless testing techniques, as already proposed in the literature. Contactless...

    For reducing the manufacturing time of integrated semiconductor circuits, it is proposed that the mask for the first metallization plane not be personalized. For this purpose, the following approach is used. 1) The transistors are wired to the logic basic function, say, a 2 W NAND circuit. Output 0 is ...

    This article describes a solution to the problem that an equipment master key must be known to a key distributer in order to generate useful enciphered keys for presentation on the key input bus. An equipment master key is a cryptographic key held in a secure module for the purpose of eciphering other keys. The...

    As it permits the simultaneous transmission of several data frames led by a locomotive, the locomotive concept is advantageous for short messages of, say, 320 data bits, for voice packets and/or rings of, say, 200 km. The frames are sent and transmitted, respectively, by one or more nodes on the ring. Also suitable...
