Patent number: 6443511Abstract: Provided in an energy absorber (1) for bumpers (2, 3) of motor vehicles are stiffening elements (5), which have front sides (6) facing away from a rear mounting structure (4). The stiffening elements (5) have in the longitudinal direction a lateral center-to-center distance from one another that corresponds to the standard dimensions of a human leg. Side faces of the stiffening elements (5) which face one another are designed such that, in the event of collision with a leg, the stiffening elements (5) are deformable independently of one another, and in the event of collision with an object larger than a leg, the stiffening elements (5) engage one another at their side faces in a manner hindering deformation with an abrupt increase in the stiffness of the energy absorber (1). By this means, braking with a relatively low deceleration is achieved in a collision with the leg, whereas the energy absorber (1) is adequately stiff in a collision with a larger object.Type: GrantFiled: July 9, 2001Date of Patent: September 3, 2002Assignee: Peguform-Werke GmbHInventor: Stefan Braun

Patent number: 6437082Abstract: The stoichiometric ratio of dihydric phenol to diarylcarbonate during production of polycarbonates can be evaluated by infrared analysis, preferably using an FTIR spectrometer, to detect the amount of BPA or other dihydric phenol in the mix tank. In one format of the method, one or both of two characteristic peaks, reflecting the methyl CH bonds and hydroxyl OH bonds are evaluated. These peaks occur equally in BPA monomers and oligomers, and hence are independent of the degree of oligomerization or polymerization which has occurred. For this reason, monitoring of stoichiometry can be performed on the contents of the mix tank, or on the products from or contents of any downstream reactors. Using a calibration curve, the absorbance associated with these bonds is converted into a measure of the concentration of BPA and from that to first moles and then grams of BPA in the mixture being tested. The amount of DPC is determined by subtracting the number of grams of BPA from the total initial sample weight.Type: GrantFiled: June 23, 2000Date of Patent: August 20, 2002Assignee: General Electric CompanyInventors: Linda McCracken, Patrick McCloskey, Eva Mardomingo-Santás, Timothy Brydon Burnell

Patent number: 6431562Abstract: The ground gliding vehicle has a gliding part (1) facing the ground, a supporting structure 2 placed upon it and a seating structure (3) attached to this supporting structure (2). On the supporting structure (2) and/or on the seating structure (3), means (5) for holding on are attached. The supporting structure (2) is equipped with a shock absorber (4) for absorbing bumps of the ground during a ride. The seating height (H) is adjustable by virtue of the fact, that the shock absorber (4) can be attached to several points (12.1-12.3) on the gliding part (1). The ground gliding vehicle can be folded up, in order to occupy less volume during transportation. When driving, the driver in essence sits upright on the seating structure (3) and looks in the direction of travel (x), so that his feet touch the ground each on one side of the gliding part (1). The driver can wear short—or extremely short skis on his feet. The ground gliding vehicle is steered mainly by the transfer of weight.Type: GrantFiled: September 28, 1999Date of Patent: August 13, 2002Inventor: Hansrudolf Vontobel

Patent number: 6429850Abstract: A signal processing system for a strain-gauge pointing device has a reduced parts count and permits the use of relatively inexpensive low-tolerance components. The system can process signals from two or three or more strain gauges, permitting additional inputs by users without a linear increase in the number of signal processing components. The system employs an RC network to develop an offset for the signal to be provided to an analog-to-digital converter. The system performs each measurement twice, once with a particular excitation polarity and again with the opposite excitation polarity, which permits correction for drift and temperature instability.Type: GrantFiled: January 16, 2001Date of Patent: August 6, 2002Assignee: USAR Systems Inc.Inventor: Victor Marten

Patent number: 6429022Abstract: The integrated-optical chemical and/or biochemical sensor comprises a resonant waveguide grating structure (1.1, 1.2, . . . ), e.g., a chirped grating. By illumination with incident light (21), a resonant electromagnetic field is excited in the grating structure (1.1, 1.2, . . . ). At least one parameter of the incident light, e.g., the angle of incidence (&thgr;1) or the wavelength (&lgr;1), is varied. Light (23) excident from the grating structure (1.1, 1.2, . . . ) is detected by detectors (4.1, 4.2, . . . ). Optionally, means for providing a feedback from the detectors (4.1, 4.2, . . . ) to the light sources may be provided, thus establishing a controlled closed-loop system. Hence independent simultaneous measurements in a multiple arrangement of such sensors (S1, S2, . . . ) is made possible. Moreover, a much higher density of sensors (S1, S2, . . . ) results.Type: GrantFiled: February 22, 2000Date of Patent: August 6, 2002Assignee: CSEM Centre Suisse d'electronique et de Microtechnique SAInventors: Rino Kunz, Max Wiki, Philipp Zeller

Patent number: 6403303Abstract: Samples are tested for mutations in the BRCA1 gene using a hierarchical approach. First, each sample is amplified in one or more multiplex PCR amplification reactions. Each multiplex PCR reaction produces a mixture of amplified fragments. The sizes and amounts of these fragments are evaluated and compared to standard values reflecting the sizes and amounts of fragments produced when the same multiplex amplification is performed on the wild-type BRCA1 gene. Differences between the observed fragment sizes and/or amounts and those for the wild-type gene are indicative of a mutation with the BRCA1 gene of the sample. Next, one or more of the exons of the BRCA1 gene are sequenced, preferably only for those samples where no mutation was detected by analysis of the multiplex PCR fragments. The sequencing procedure can be performed by amplification and sequencing of the multiplex amplification mixture.Type: GrantFiled: May 14, 1996Date of Patent: June 11, 2002Assignee: Visible Genetics Inc.Inventors: Robert Shipman, James Leushner, James M.

Patent number: 6404907Abstract: Nucleic acid polymers are sequenced by obtaining forward and reverse data sets for forward and reverse strands of a sample nucleic acid polymer. The apparent base sequences of these forward and reverse sets are determined and the apparent sequences are compared to identify any deviations from perfect complementarity. Any such deviation presents a choice between two bases, only one of which is correct. A confidence algorithm is applied to the peaks in the data sets associated with a deviation to arrive at a numerical confidence value for each of the two base choices. These confidence values are compared to each other and to a predetermined threshold, and the base represented by the peak with the better confidence value is assigned as the “correct” base, provided that its confidence value is better than the threshold. The confidence value takes into account at least one, and preferably more than one of several specific characteristics of the peaks in the data set that were not complementary.Type: GrantFiled: June 25, 1999Date of Patent: June 11, 2002Assignee: Visible Genetics Inc.Inventors: Rodney D. Gilchrist, James M. Dunn

Patent number: 6400285Abstract: A keyboard system is provided for use in data entry. The keyboard generates signals indicative of key closures, and also generates signals indicative of the pressure with which the user has pressed the keys. If the pressure exceeds a threshold, such as 200 grams, for a pressures averaged over a predetermined interval, such as three minutes, then this event is annunciated. In a single-user environment the annunciation is to the user. In a multi-user environment the annunciation is to a system manager. Optionally wrist support pads are also provided in front of the keyboard, each of which is equipped with a pressure sensor. The system monitors the wrist pad pressure readings to detect unfavorable combinations of wrist pad pressure and key depressions. The support pad may be shaped with a hole through which the operator places the hand, which is thus useful for teaching proper technique and assisting a user in avoiding injury.Type: GrantFiled: October 8, 1992Date of Patent: June 4, 2002Inventor: Henry Gifford
