  • Patent number: 6782332
    Abstract: Method, apparatus and computer programs are described for compensating for the effect of temperature on the sensitivity of electrostatic ultrasound (US) transducers, particularly as used in an automotive occupancy sensing (AOS) systems for sensing the nature or type of occupant and the location of the occupant with respect to the vehicle interior. The invention permits the AOS to classify the occupancy state of the vehicle from a US echo signal substantially free of the effects of temperature on signal amplitude. A capacitive divider or voltage monitor is employed to measure the capacitance of the transducer. The voltage monitor output is used by the scaling algorithm of a compensator to determine the scaling factor to be applied to the US transducer signal to compensate for the effect of temperature on the transducer sensitivity.

  • Patent number: 6633475
    Abstract: A low cost high side supply shut down circuit that operates to deactivate the power supply of a central supply, such as to pressure regulators, solenoid valves, etc., as parts of non-repairable electro-hydraulic transmission modules in the event of a malfunction, e.g. a low side driver circuit failure. The supply voltage is connected to the high side of a fuse. The load circuits receive power or no power depending on the operating condition of the fuse. Coupled across the fuse is a fuse trigger status detection circuit as part of a diagnostics and control module. The diagnostics and control module is connected to the input of a shut down low side output driver circuit. The attached low side loads have individual detection circuits that are coupled to the diagnostics and control module as well as their enable inputs.

  • Patent number: 6566544
    Abstract: This invention is directed to novel catalysts the structure and activity of which can be controlled to produce a wide range of alpha olefin polymers and co-polymers, and preferably for the production of stereoblock poly alpha olefins comprising a wide range of preselected amorphous and crystalline segments for precise control of the physical properties thereof, principally elastomeric thermoplastic properties. More specifically, this invention is directed to novel catalysts and catalysts systems for producing stereoblock polypropylene comprising alternating isotactic and atactic diastereosequences, which result in a wide range of elastomeric properties. The amount and numbers of crystalline sections, the isotactic pentad content, the number and length of intermediate atactic chains and overall molecular weight are all controllable by the steric structure of the catalysts and the process conditions.

  • Patent number: 6559262
    Abstract: This invention relates generally to low ethylene insertions into I-olefin polymers and processes for production of such polymers using unbridged fluxional metallocenes, primarily substituted aryl indenyl metallocenes, and more particularly to use of unbridged, fluxional, cyclopentadienyl or indenyl metallocene catalyst systems in methods of production of high melting point I-olefin homo- and co-polymers, particularly elastomeric crystalline and amorphous block homo- and co-polymers of I-olefins. The activity of fluxional unbridged metallocene polymerization catalysts containing at least one 2-arylindene ligand is increased 10× or more by the addition of small (typically 0.1-10 wt. %) amounts of ethylene to the polymerization system, which increase is termed the Polymerization Rate-Enhancement effect (PRE), which is measured in terms of an Ethylene Enhancement Factor (EEF) as a dimensionless ratio in the range of from about 1.1 to about 10 or above.

  • Patent number: 6518378
    Abstract: This invention relates to high melting polyolefin copolymers suitable as thermoplastic elastomers and catalysts and methods for their synthesis. These elastomeric olefin copolymers are characterized by a mole fraction of crystallizable component Xc from about 30 to about 99%; low glass transition temperatures, below −20° C., and typically below −50° C.; melting points above about 90° C.; high molecular weights; a molecular weight distribution MW/Mn</=10; and a narrow composition distribution between chains of </=15%. The novel copolymers of the invention range from reactor blends to multiblock copolymers that can be sequentially fractionated into fractions of differing crystallinities, which fractions nevertheless show compositions of comonomers which differ by less than 15% from the parent polymer (reactor product).

  • Patent number: 6479685
    Abstract: Metallocene catalysts having plural coordination geometries for synthesis of high melting polyolefin copolymers suitable as thermoplastic elastomers. The inventive catalysts comprise unbridged, substituted or unsubstituted cyclopentadienyl metallocene catalysts that are capable of inter-converting between states with different polymerization or copolymerization characteristics, which interconversion is controlled by selecting the substituents of the cyclopentadienyl ligands so that the rate of interconversion of the two states is within several orders of magnitude of the rate of formation of a single polymer chain. Where ri>rf the polymer can be characterized as multiblock; where ri<rf, the result is a polymer blend and where ri/rf is close to 1, the resulting polymer is a mixture of blend and multiblock. The inventive metallocene catalysts are able to interconvert between more than two states, with embodiments of four states being shown in FIG. 2.

  • Patent number: 6390892
    Abstract: Described is a method for the cutting machining of non-circular contours using a tool in the shape of a cone or a truncated cone positioned on a spindle for rotation, said spindle aligned at a certain angle with the workpiece axis on which the workpiece with the contour is positioned, whereby the tool is swiveled during the machining about at least one first swivel axis that is different from the spindle axis. Alternatively, the workpiece can be moved correspondingly, and the tool may remain unchanged in its alignment. Tool and workpiece also may undergo a corresponding movement together, since the crucial factor is solely the relative movement between tool and workpiece. Also described is a device for performing the method.

  • Patent number: 6272411
    Abstract: A system for sensing the presence, position and type classification of an occupant in a passenger seat of a vehicle, as well as for sensing the presence of a rear-facing child seat therein, for use in controlling a related air bag activator control system to enable, disable or control inflation rate or amount of inflation of an air bag. The sensor system employs sensor fusion, a process of combining information provided by two or more sensors (24, 26), each of which “sees” the world in a unique sense. In a preferred embodiment, infrared sensor inputs (78) and ultrasonic sensor inputs (79) are combined in a microprocessor by a sensor fusion algorithm (80) to produce an occupancy state output signal (85) to the air bag controller.

  • Patent number: 6266593
    Abstract: An automotive occupancy sensing system and method for use in conjunction with airbag deployment systems, by which occupant nature, location and motion parameters within the vehicle interior are determined by ultrasound (US) and/or infrared sensors. (IS). Criteria for airbag disablement or airbag modified/partial deployment are used to determine whether appropriate disablement or modified/partial deployment control signals are transmitted to the vehicle airbag deployment system. More particularly the system establishes a Keep Out Zone (KOZ) within the vehicle interior relative to the dashboard or instrument panel and determines actual or imminent incursions by occupants into the KOZ to produce a Keep Out Zone Incursion (KOZI) signal. The system is also characterized by establishing a “Gray Area” bounding the KOZ.

Criteria for airbag disablement or airbag modified/partial deployment are used to determine whether appropriate disablement or modified/partial deployment control signals are transmitted to the vehicle airbag deployment system. More particularly the system establishes a Keep Out Zone (KOZ) within the vehicle interior relative to the dashboard or instrument panel and determines actual or imminent incursions by occupants into the KOZ to produce a Keep Out Zone Incursion (KOZI) signal, and determines crash-imminent signal (CIS) criteria derived from one or more sensors within the vehicle. Both the KOZI and the CIS may be used to increase the rate of US pinging as well as to determine airbag disablement/modified deployment criteria.
