  • Patent number: 6188227
    Abstract: A test system having a bifilar wound isolation network disposed in between a device under test (DUT) and a device under test support system for providing a high isolation impedance to common mode signals present at the input terminals of the isolation network, while still providing a relatively lossless path for differential signals present across the input terminals of the isolation network. The isolation network comprises a plurality of four resonators each having a precise, predetermined number of turns and serially interconnected by a bifilar winding. The bifilar winding allows coupling to the inputs of a balanced DUT and enables a worst case operating environment to be provided for the balanced DUT to assist in testing and/or design of the DUT so as to minimize the effects on the DUT of electromagnetic interference and to assist in modifying the balanced DUT so as to immunize it from susceptible EMI receptors therewithin.

  • Patent number: 6163785
    Abstract: The present invention is a system of integrated, computer-based processes for monolingual information development. and multilingual translation. An interactive text editor enforces lexical and grammatical constraints on a natural language subset used by the authors to create their text, which they help disambiguate to ensure translatability. The resulting translatable source language text undergoes machine translation into any one of a set of target languages, without the translated text requiring any postediting.

  • Patent number: 6152702
    Abstract: An apparatus and method for sensing a parameter of a hydraulic pump. The hydraulic pump includes a housing and an input shaft. The shaft is rotationally driven relative to the housing and electrically coupled to the housing. The hydraulic pump forms a variable capacitor. The apparatus includes an electrode portion positioned adjacent to the input shaft and is electrically isolated from the housing and input shaft. The electrode portion and the input shaft form a fixed capacitor. The fixed capacitor and the variable capacitor are coupled. The apparatus supplies electrical energy to the electrode portion and produces a capacitive signal indicative of the capacitance value of the variable capacitor. The apparatus further applies a filter to the capacitive signal and produces a filtered capacitive signal. The parameter of the hydraulic pump is determined as a function of the filtered capacitive signal.

  • Patent number: 6151537
    Abstract: A method for determining the tractive effort required at the wheels of a vehicle for a given set of operating parameters by taking into account a plurality of variables which affect vehicle performance. A total grade effort value is determined which represents the force required to move the vehicle due to the grade of the surface on which the vehicle is expected to travel. An approximate total rolling effort value is also determined which is representative of the force required to move the vehicles due to the hysteresis of the vehicle's tires. Lastly, an aerodynamic influence factor is determined which represents the total air resistance of the vehicle and any implement such as a trailer being towed by the vehicle. These factors are summed to produce a tractive effort value representative of the total tractive effort that would be required to move the vehicle at a designated speed.

  • Patent number: 6098265
    Abstract: An apparatus and method for positioning a latch assembly and a striker on a motor vehicle is disclosed. The apparatus is designed to improve the fit of the tailgate to the side walls or truck body. A good fit is defined as the outer surface of the tailgate and the outer surface of the side wall being coplanar when the tailgate is in the closed position. The apparatus, by way of a first formation and first locating element, determines the position of the latch assembly with respect to outer surface of the tailgate. The apparatus, by way of a second formation and second locating element, also determines the location of the striker with respect to the outer surface of the side walls. The apparatus, by way of a body member, also determines the position of the striker with respect to the latch assembly and vice versa. By setting the latch assembly and the striker by the above relations, build variances of the tailgate and of the truck body are eliminated as a possible cause for a poor fit.
