Abstract: PROBLEM TO BE SOLVED: To effectively support a driving operation of a driver for parking without requiring a sensor with high accuracy. SOLUTION: Because a steering wheel Wf is automatically steered based on a preliminarily stored advancing moving locus while a vehicle V moves forward from a parking starting position P1 up to an advancing direction switching position P2, the vehicle V can be rightly stopped at the advancing direction switching position P2. Therefore, only if a driver holds a steering angle θ max at the advancing direction switching position P2 while the vehicle V moves backward from the advancing direction switching position P2 to a parking termination position P3, the vehicle V can be rightly guided to the parking termination position P3.  Because the driver can perform a fine adjustment for an advancing direction by operating a steering wheel while the vehicle V moves backward, even if a slight error exists at a stop position of the vehicle V at the advancing direction switching position P2, a highly accurate sensor is not required to be used as each kind of sensor for performing the automatic steering and it can be contributed to reduction of cost.

Abstract: Fast methods of tone detection and tone generation disclosed are particularly suitable for implementation in a digital signal processor. Chebyshev polynomials are employed to generate periodic waveforms and to detect such waveforms. In an alternative aspect of the invention, trigonometric formulae are employed to generate periodic waveforms which are representable as the sum of sine and cosine functions. Unlike analog techniques, the digital techniques do not entail long delays in the generation or detection of tones because a fast iterative recalculation is employed at each step. Accumulated error is avoided by restarting the procedure once a predetermined value is exceeded. Independent choice of a quality factor and a confidence level is provided by the digital tone detection technique.

Abstract: A carton for holding several cigarette packs is made so that it generally resembles and functions like a conventional hinge lid cigarette pack. The carton is made from an integral blank 100 including innerframe panels E, F, G and outer member panels A, B, C, D, all arranged in a single side by side series. When the blank is folded to make the carton, the innerframe panels are positioned inside the appropriate outer member panels. The blank also includes top B2 and bottom B3 cover panels which can be closed in order to close the carton after the innerframe panels have been folded inside the outer member panels. A particularly preferred method of making up the carton is described. The consumer opens the carton by pivoting an upper portion of the outer member up and to the rear just as with a conventional hinge lid cigarette box. The innerframe interferes somewhat with this lid motion, thereby helping to keep the lid closed as in a conventional hinge lid cigarette box. <IMAGE>

Abstract: The present invention relates to an improved method for the amplification of nucleic acid. The invention is characterized in that ribonucleotides are introduced during amplification that weaken normal basepairing. Preferably the ribonucleotides are inosine-triphosphate nucleotides which partly substitute guanine-triphosphate nucleotides normally present in the amplification reaction mixture. The incorporation of nucleotides, during amplification, that weaken normal base pairing prevents the formation of secondary structures in the amplificate. The efficiency of the amplification is thereby increased. The introduction, during amplification, of nucleotides that weaken normal base pairing also results in an improved sensitivity during detection of the amplified nucleic acid, when the detection method comprises the hybridization of the amplified nucleic acid to a complementary sequence.

Abstract: The present invention describes a method for calling up information by means of a mobile telephone. The SMS messages of a mobile telephone are used to call up information which is unconnected in time and location with the mobile telephone. To specify the desired information and to define the brief commands the user of the mobile telephone uses data-processing equipment with data lines to the information provider, e.g. Internet connection, by means of which he can deposit query profiles with the information provider. In addition, the query profiles can be produced using a speech computer. The user can call up the dormant query profiles by means of simple brief commands and obtain the required information. The desired information will be reproduced either visually or acoustically via the mobile telephone. The advantages of both communication media are therefore combined with one another in an ideal manner, where the hardware of the mobile telephone and/or its method of operation remain unchanged. <IMAGE>
