  • Method for determining the deceleration of a motor vehicle
    Patent number: 6254203
    Abstract: The deceleration o motor vehicle resulting from a vehicle brake is defined as the difference between a total deceleration of the motor vehicle and decelerations caused by the engine, wind, friction and grade, and a product of contact-pressure forces of the vehicle brake using a proportionality factor which is dependent on a brake temperature and a load being carried. The ratio of the two values is then used as a parameter for correcting the proportionality factor.

  • Reversible surgical gown
    Patent number: 4106120
    Abstract: A reversible, back opening surgical gown, capable of enclosing the wearer from neck to mid calf exposes a "surigically clean" or "sterile" exterior surface. The gown, because of its symmetry, is capable of exposing either of its fabric surfaces as its exterior sterile surface when enveloping the body of a wearer. As such, it avoids the necessity of reversing the gown, as in a laundry, after use, to expose a usable exterior surface, required by conventional asymmetric gowns.

  • Regulation of processing stages of a fiber processing installation
    Patent number: 4876769
    Abstract: The fiber processing installation monitors the operation of a discontinuously operating stop/go stage to obtain an actual value signal corresponding to the ratio of operative time to inoperative time as well as the total production of a continuously operating downstream stage, such as a card room, to establish a set value signal. A deviation of the actual value from the set value provides a control signal to adjust the ratio of operative time to inoperative time of the upstream stage so as to maintain the total production of the installation constant.

  • Evaluation configuration for semiconductor memories
    Patent number: 6806550
    Abstract: An evaluation configuration has a first MOS evaluation stage, an isolation stage, and a bipolar evaluation stage. The isolation stage is connected between the first MOS evaluation stage and the bipolar evaluation stage. The isolation stage isolates the first MOS evaluation stage from the bipolar evaluation stage. The evaluation configuration can reliably detect very small read signals and allows a high integration density.

  • Data transmission method with a plurality of frequency bands
    Patent number: 6396802
    Abstract: The invention relates to a data transmission method in which the data to be transmitted are divided into a plurality of subchannels each with a normal component and a quadrature component that is orthogonal to the normal component. The divided data are transmitted in different frequency bands. The frequency bands are arranged with non-equidistant frequency spacings between one another. An error signal is generated at the reception end for each subchannel both for the normal branch and for the quadrature branch and fed to a corresponding reception filter.

  • Vehicle restraint and method for modifying the same
    Patent number: 6371714
    Abstract: A vehicle restraint comprising a base member (e.g., a track), a carriage movably mounted to the base member, and a restraining member (e.g., a pivotable hook) mounted to the carriage and movable between and engaged position and a disengaged position. The restraining member is biased toward the engaged position. The restraining member is biased by a biasing member in the form of a gas spring operatively positioned between the restraining member and the carriage. The restraining member is pivotable, and the restraint further includes a lever interconnected with the restraining member. In this embodiment, the biasing member is interconnected with the lever to bias the restraining member toward an engaged position. The biasing member can be positioned to bias the restraining member toward the disengaged position when the restraining member is in the disengaged position and to bias the restraining member toward the engaged position when the restraining member is in the engaged position.

  • Dial tone speed monitor
    Patent number: 3968335
    Abstract: Apparatus for connection to the line finder group busy signal leads of telephone office equipment to determine when each line finder group is and is not busy, make an averaging determination of the busy conditions and generate signals indicating this average condition of busy activity on the monitored lines. The apparatus includes a parallel to serial multiplexer for cyclically sequentially sampling the line finder busy signal leads, means for selecting which of the leads are to be sampled, and a divide-by-N counter settable to count a predetermined number of pulses received from the multiplexer equal to the number of leads selected for monitoring, and to generate an output signal after each receipt of such predetermined number of pulses. The timing of the apparatus is so arranged that each generated output signal directly represents a busy time of 0.1% of an hour or 3.6 seconds.
