Patent CA-2115350-A1 (CA)
Inventor: KOEHLER DIETER
IPC: B64C3/18
Filed: 1993-06-30
Abstract: ABSTRACT OF THE DISCLOSURE      The invention concerns a plastic composite profiled girder, in particular an aircraft wing spar, comprising at least two chords with bonding flanges and at least one web inserted into the bonding flanges and connecting the chords to each other.  The chords are made from resin-impregnated rovings and the web is made from resin-impregnated wovens or layups, and the chords and web are joined to each other by adhesive bonding.  The chords are produced by pultrusion, the web being inserted into the bonding flange of both chords and fixed there using a thixotropic adhesive.  This construction ensures that the full flange bonding width is maintained even if the height of the component is varied.

Abstract: An image coding method includes the steps of producing a complexity normalizing value of respective macro blocks based on a complexity in a space domain with regard to an input image, producing a zero coefficient sum by performing a discrete cosine transform operation on the input image and counting the discrete cosine transform coefficients from -1 to +1, producing a zero coefficient normalizing value for respective macro blocks in accordance with the zero coefficient sum; producing a transient weight for respective macro blocks in accordance with the zero coefficient sum and a predetermined compression ratio, and summing the complexity normalizing value, the zero coefficient normalizing value and the transient weight so as to produce the scale factor. The quantization step size of the discrete cosine transform coefficients is controlled in a macro block unit in accordance with the scale factor. Thus, image frames having various complexities can be encoded at a constant bit rate with no deterioration of the image.

Patent CA-2140622-A1 (CA)
Inventor: GAGNON ROBERT E
IPC: B64F5/00
Filed: 1995-01-12
Abstract: There is described a method and apparatus for detection and thickness evaluation of a buildup of a solid, e.g. ice, or liquid on a solid surface, such as ice on a body of an aircraft.      The apparatus comprises a source of a narrow beam of radiation and a means for remote evaluation of the size of a luminous area created on the solid surface by the beam.      The method of the invention involves measuring the size of the luminous area and determining the thickness of any built-up layer, if sufficiently transparent, using a formula which uses the dependency of the size of the luminous are on the thickness of the layer and the refraction index of the medium. Differentiation between ice and a liquid is possible by evaluating regularity of illumination of the luminous area.

IPC: H04N21/2343
Filed: 1995-03-07
Abstract: A method and device for transcoding a digital signal first oversamples the input signal, converts the sampling rate to an oversampled output signal, filters the signal to reduce unwanted bands and decimates the oversampled output signal to produce a transcoded signal having the target sampling rate. This allows the conversion to be implemented in the composite domain, requiring a single sampling rate converter, and significantly reduces the complexity of the filter required to filter the output signal .

Title: System for coating a substrate with a reinforced resin matrix
Inventor: HALL TERRY L
IPC: B05B7/14
Filed: 1993-11-17
Abstract: Coating a substrate with a reinforced resin matrix comprised of liquid resin and reinforcing material can be accomplished with an apparatus where the liquid resin and the reinforcing material are mixed external to the apparatus prior to impacting the substrate. The liquid resin is directed through a cylinder (12) and then through an orifice (7) in nozzle (1), while the reinforcing material is carried in a gas stream through cavity (13), around cylinder (12), and past the nozzle (1). As the reinforcing material passes the nozzle (1), it is drawn into the liquid resin. Due to the distribution of the reinforcing material around the liquid resin flow, the reinforcing material is substantially homogeneously wetted by the liquid resin prior to impacting the substrate.

Abstract: The  present  invention  provides  an  aqueous-based suspoemulsion of agricultural chemicals, more specifically, a combination of an emulsion concentrate of a triazole, morpholine or pyrimidine, and a dithiocarbamate such as mancozeb  or  maneb  as  the  suspended  solid  component, characterized in that the suspoemulsion also comprises a polymer of propylene oxide and ethylene oxide, the polymer having at least 40 mol% polyoxyethylene units, a central polyoxypropylene    portion,    and    the    formula HO(CH2CH2O)x(CH(CH3)CH2O)y(CH2,CH2O)zH where x, y, and z are such that the molecular mass of said portion is at least 1200.   The advantage of such a formulation over simple mixtures  of  agricultural  chemicals  is  that  the  two components can be chemically isolated from one another, thereby preventing interactions which may lead to breakdown of the system.   As a consequence a ready-mixed liquid formulation can be supplied to the farmer for immediate application.

Title: Systems with Increased Information Rates Using Embedded Sample Modulation and Predistortion Equalization
Inventor: NEWHALL EDMUNDE EUGENE
IPC: H04B7/005
Filed: 1993-07-09
Abstract: A system is described which achieves an increased rate of transmission by transmitting multiple symbols in one symbol time. The infor-mation in the overlapping symbols can be recov-ered if the symbol used for transmission is chosen so that a subset of the samples representing the symbol has an inverse. The construction of suit-able symbols is illustrated.  Effective operation of the system depends on equalization which will recover the baseband signal shape. Methods of equalization are depicted which are suitable for use with this system including equalization real-ized by predistorting the signal at the transmit-ter so that it arrives at the receiver undistorted. The invention is applied to baseband and pass-band systems and the application of predistortion equalization to the fading passband channel is de-scribed.
