Abstract: An apparatus for detecting a faulty concentric neutral wire in a live power distribution cable may include, in one embodiment, a housing for sliding along a surface of a power distribution cable, a magnetic sensor, and a motion device. The magnetic sensor may be coupled to the housing and configured to detect a magnetic field produced by each concentric neutral wire as the housing moves along the surface of the cable. The motion device may also be coupled to the housing, and may detect motion of the housing relative to the cable. In some embodiments, a communication device may communicate data describing the magnetic field and motion to a destination device.

Abstract: A device for variable activation of valves for internal combustion engines, which is arranged in a cylinder head having a camshaft mounted in a fixed location with valves that close by means of spring force through a stroke transfer arrangement. This device includes a movable element mounted with a fixed pivot, and has a support cam and a control cam. An intermediate member is displaceably mounted and supported on the element, and is in engagement with a cam lever of the camshaft, as well as the stroke transfer arrangement. The intermediate member supports itself on the support cam and control cam with a non-positive lock, sliding during the stroke movement. Whereby the control cam determines the stroke movement to be transferred to the stroke transfer arrangement by the intermediate member, as a function of the pivot position of the element that can change its position.

Abstract: A device for variable activation of valves for internal combustion engines, which is arranged in a cylinder head having a camshaft mounted in a fixed location. The device has valves that close by means of spring force, and which are guided in a fixed location in the cylinder head together with a stroke transfer arrangement assigned to one of each of the valves. This device includes a movable element that is changeable in its position for setting the valve stroke setting. This movable element is arranged in the cylinder head, in a fixed location, as well as mounted so as to pivot about a pivot axis having a fixed position in the cylinder head, and has a support cam and a control cam. There is also an intermediate member that is supported on the element that can change position, and wherein this intermediate member is displaceably mounted, and is in engagement with a cam lever of the camshaft, as well as the stroke transfer arrangement.

Abstract: Apparatus and method for performing IEEE-rounded floating-point division utilizing Goldschmidt's algorithm. The use of Newton's method in computing quotients requires two multiplication operations, which must be performed sequentially, and therefore incurs waiting delays and decreases throughput. Goldschmidt's algorithm uses two multiplication operations which are independent and therefore may be performed simultaneously via pipelining. Unfortunately, current error estimates for Goldschmidt's algorithm are imprecise, requiring high-precision multiplication operations for stability, thereby reducing the advantages of the pipelining. A new error analysis provides improved methods for estimating the error in the Goldschmidt algorithm iterations, resulting in reductions in the hardware, improved pipeline organization, reducing the number and length of clock cycles, reducing latency, and increasing throughput.

Abstract: An IEEE floating-point adder (FP-adder) design. The adder accepts normalized numbers, supports all four IEEE rounding modes, and outputs the correctly normalized rounded sum/difference in the format required by the IEEE Standard. The latency of the design for double precision is roughly 24 logic levels, not including delays of latches between pipeline stages. Moreover, the design can be easily partitioned into two stages comprised of twelve logic levels each, and hence, can be used with clock periods that allow for twelve logic levels between latches. The FP-adder design achieves a low latency by combining various optimization techniques, including a non-standard separation into two paths, a simple rounding algorithm, unifying rounding cases for addition and subtraction, sign-magnitude computation of a difference based on one's complement subtraction, compound adders, and fast circuits for approximate counting of leading zeros from borrow-save representation.

Abstract: A method and apparatus for improving the efficiency of hardware-based binary multiplication. By using radix-32 and radix-256 multipliers where each radix-32 digit is represented by two radix-7 digits and each radix-256 digit is represented by three radix-11 digits, the digit magnitudes are in power of two, which simplifies the implementation of the partial product generation. The partial products depending on multiples of the radices 7 or 11 can be separately accumulated, with multiplication by the radix a pre- or post-computation option.

Abstract: A damping element is proposed for a conduit conducting a gaseous or liquid medium through which pressure pulsations are applied, which is constructed as a hollow body through which the medium can flow, and is attached to a fastening element in such a way that the damping element is pushed into an opening provided in the fastening element. The inner surface of the fastening element may be provided with elevations and/or depressions produces a connection with enhanced frictional grip between the damping element and the fastening element.

Abstract: A device for damping the sound emission from oscillatory components of a fluid container of a hydraulic system, primarily in a motor vehicle. At least one vibration damping mass is coupled to the wall of a component subject to sound damping. The mass is adapted to the vibration to be damped by selection of material, shape, and/or position on the wall. For example, the mass is a rib fastened to the wall or a strip adhered to the wall. In an alternate embodiment, the container has an inner and an outer wall with a gap between them. The gap is either evacuated, filled with a sound absorbing material or ribs on the wall extend in the gap or inside the inner wall.
