    Abstract: A position securing system for restraining an occupant in a vehicle includes a harness placed about an occupant's body and including a two-part lap belt defining two lap belt straps, two leg loops, a rear belt, two shoulder belts, a back belt, and a belly-side center buckle. Anchored to the vehicle and interacting with the lap belt straps are a plurality of retractors connectable to the vehicle and interacting with the shoulder belts and the belt straps of the lap belt in one-to-one correspondence, wherein at least the retractors interacting with the lap belt straps are each constructed to include a winding drum for winding in a reel-in direction a traction member which is integrated in the lap belt strap, with the winding drum loaded by a spring in the reel-in direction. Rotation of the winding drum at least in a pay-out direction of the traction member is automatically blocked by a locking mechanism, when the occupant assumes the seated position.

  • Patent number: 6078049
    Abstract: A stable isotope analyzer is concentration calibrated by measuring relative proportions of isotopes in a measurement gas. The measurement gas is a component of a gaseous mixture consisting of the measurement gas and one other gas or a mixture of gases containing none of the measurement gas. First, a mixture is produced with a relatively high concentration of the measurement gas and known isotope proportions. The concentration of the measurement gas in the other gas is determined and the isotope proportion is measured to determine a point on a calibration curve (measured isotope proportion values vs. measured concentration values). At least one further point on the calibration curve is determined by diluting the measurement gas in the mixture by introducing a gas or gaseous mixture containing no measurement gas. The reduced concentration is determined and the isotope proportion measured to determine another point on the calibration curve.

  • Patent number: 6069498
    Abstract: An apparatus has a clock monitoring device, which determines whether or not the clock rate of an input clock signal (.PHI..sub.0) has fallen below a predetermined minimum clock rate. A system is provided which, from the input clock signal, forms a master clock signal (.PHI..sub.m) and a slave clock signal (.PHI..sub.s) which are in a form such that both the switches (S1) of dynamic master registers (ML) and the switches (S2) of dynamic slave registers (SL) are closed provided that the clock rate has fallen below the minimum clock rate. Otherwise, at most either the switches (S1) of the dynamic master latches (ML) or the switches (S2) of the dynamic slave latches (SL) are closed. The primary advantage achieved hereby is that in the event of failure of the input clock signal, in particular in circuits with a high degree of pipelining, undefined register states do not result in an impermissibly high current consumption.

  • Patent number: 5854567
    Abstract: The integrated circuit with a clock system, particularly a CMOS circuit with extensive pipelining, whereby an optimally low overall dissipated power is effected in that a clock driver circuit is provided with a specifically wired driver output stage that generates a clock supply voltage that corresponds to about half the value of a general supply voltage. A great reduction of the dissipated power can be achieved given relative slight sacrifices in the performance capability.
