  • Publication number: 20060025893
    Abstract: The invention relates to a method for assisting the driver of a vehicle (10) when performing a driving maneuver, such as a parking or shunting maneuver. In this case, a reference trajectory (16) is determined, along which the vehicle (10) is to be moved. A steering wheel position to be set and controlling the vehicle along the reference trajectory (16) is indicated to the driver during the driving maneuver. The vehicle longitudinal speed is influenced independently of the driver in the event of a steering angle deviation between the actual steering angle actually set by the driver and the desired steering angle corresponding to the requested steering wheel position. As a result, the driver can be given a greater reaction time in order to set the indicated steering wheel position.

  • Publication number: 20060017003
    Abstract: A device for dynamically biasing an ion optic element, for example, in a mass spectrometer. The device includes a voltage source, a first ion optical element coupled with the voltage source, a second ion optical element resistively coupled with the first ion optical element; and a pulse generator capacitively coupled with the second ion optical element. The pulse generator is configured to apply a series of pulses to the second ion optical element. In steady state operation, a dynamic voltage bias is generated between the first ion optical element and the second ion optical element. The dynamic voltage bias is controllable by controlling the characteristics of the applied pulses, such as the pulse width, pulse amplitude, and pulse repetition rate of the applied pulses.

  • Publication number: 20060019009
    Abstract: A method for making a low carbohydrate high protein puffed snack food product. Ingredients comprising soy isolate, soy concentrate, corn meal, and water are introduced into an extrudate. The ingredients are extruded through a die orifice at a high specific mechanical energy. The ingredient formula ranges have been determined that maximize volumetric expansion and the set operating conditions and keep texture, color, and flavor acceptable. The puffed snack is then dried and seasoned. There are minimal off-flavors in the product.

  • Publication number: 20060020393
    Abstract: The invention provides a method of determining an amino acid sequence of a parent polypeptide.

Also provided is a method of determining the amino acid sequence of a polypeptide.

  • Publication number: 20060012211
    Abstract: A cover for the bed of a pickup truck provides a front rigid panel fastened to the front wall of the pickup bed, at least one intermediate rigid panel attached to the front rigid panel by a first transverse hinge, and a rear rigid panel attached to the intermediate rigid panel by a second transverse hinge. The rear rigid panel has a tailgate locking lip flaring downwardly and outwardly to prevent the tailgate from opening. In the fully covering position, the pickup bed cover provides a water-resistant, locked cargo area. In the partially covering position, the rear rigid panel and, optionally, the intermediate rigid panel fold forward to permit access to the cargo bed. Another pickup bed cover according to the applicant's invention provides a frontmost rigid panel fastened to a toolbox mounted in the pickup bed, at least one intermediate rigid panel attached to the front rigid panel by a first transverse hinge, and a rearmost rigid panel attached to the intermediate rigid panel by a second transverse hinge.

  • Publication number: 20060014507
    Abstract: A radio receiver (30) comprises an ADC (13) including a clip counter. The power of digitised signals provided by the ADC (13) is estimated by a power estimator (31), and an ideal gain value is computed from the power so estimated by a gain computation device (32). Gain computation signals are fed to a gain control input of an amplifier (11) via an LPF (33). A saturation detector (34) is connected to a clip counter output of the ADC (13), and to a control input of the LPF (33). The saturation detector (34) is arranged when saturation of the ADC is detected to reduce the gain setting value by at least two steps, by which the gain of the amplifier is immediately reduced. A detector detects the Doppler frequency of signals received and accordingly determines the size of the drop in amplification which is effected when saturation of the ADC (13) is detected. The gain reduction may be 3 dB under very low Doppler shift conditions and 12 dB under very high Doppler shift conditions.

  • Publication number: 20060008799
    Abstract: The present invention includes a method for rapid haplotyping a DNA or RNA segment. Two or more target sites on a segment of DNA or RNA are labeled with separate distinguishable luminescent hybridization probes, where the targets are selected genetic markers. A dilute solution is formed containing the labeled DNA or RNA segments. Each DNA or RNA segment is illuminated with light beams effective to excite each luminescent hybridization probe, when present. The presence or absence of each luminescent hybridization probe on each DNA or RNA segment is detected to determine the haplotype of each DNA or RNA segment.
