Abstract: An adaptive control system for categorized engine conditions is disclosed in which the engine conditions to be controlled are discrimated and classified in accordance with the driver's intent (ϑ ac , ϑ br ) and the vehicle operating conditions (v, N). It is decided that a given engine control condition (m = 1, 2, 3, 4) is continued or the transition is under way between different control conditions as a history judgement (ℓ, m, i, n (ℓ, m)), and a vehicle operation parameter (N IDL , G f , I g ) is determined in accordance with the determined history (m, ℓ). At the same time, in accordance with the control condition decided and classified, an operating signal (INJ, IGN) is applied to the engine with an operating parameter thus determined and the result of engine control response is observed to update the adaptive parameter (K(ℓ)).

Abstract: A conformal coating composition is made from a mixture of acrylamide functional polydimethylsiloxane, a methacrylate functional/dialkoxy polydiorganosiloxane, reactive diluent including isobornyl acrylate, cyclohexyl acrylate, and 2-ethylhexyl acrylate; a photoinitiator combination of 2-hydroxy-2-methylphenylpropanone and 2-methyl-1-[4-(methylthio)phenyl]-2-morpholenopropanone, an amine including dimethylethanolamine and diisopropylethyl­amine, and an organic titanate. The composition has a viscosity of from 0.07 to 0.2 Pa·s at 25°C. and cures by exposure to ultraviolet radiation and to atmospheric moisture, i.e. a dual curing composition. This composition cures too fast by exposure to ultraviolet radiation in the presence of nitrogen resulting in a distorted surface. Therefore, for coating printed circuit boards, it is recommended that it be cured in air so that the rate of cure is reduced and no surface distortions are formed.

Abstract: A process for producing polymer-bonded solids agglomerates by shaping agglomeration of the moistened, finely disperse solids with the use of additional polymeric binders in the agglomeration process is described. The invention is characterised in that the binders used are polymers which are swellable and/or soluble in the liquid phase used for moistening and contain acid groups which are suitable for forming insoluble salts and can also be present as soluble salt groups, the polymeric binder is combined before or during the shaping agglomeration with the finely disperse solids and contacted there with cations which are soluble in the liquid phase used for moistening and react with the acid groups  of the polymeric binder to give the insoluble solid. Preferably, polyvalent metal cations which, in particular, are introduced into the process in the form of soluble salts are used for solidifying the polymeric binder.

Abstract: An integrated circuit chip package is described wherein the chip (18) has an active face including a plurality of input and output pads (30). The chip is mounted face down on a plurality of flexible inner beam leads. The package's outer beam leads are bonded to pads residing on an underlying circuit board (26). A convective heat sink (32) is thermally mounted to the reverse face of the chip, which heat sink is formed from folded thin metal sheet. The heat sink exhibits both minimum mass, and optimum cooling efficiency. The minimum mass reduces the cost of the heat sink through material savings and minimizes the possibility of damage to the package caused by sudden accelerations. The heat sink, in addition to itself being somewhat flexible, is provided with mounting points (60) which are physically connected to the underlying circuit board via resilient connecting means.

Abstract: A novel surface working pad assembly is described which assembly comprises a fibrous generally disc shaped pad support element (1) having a circular raised portion (2) at its center. The raised portion (2) is sized and configured to fit closely within a circular aperture (7) of a cooperating surface working pad element (6), but preferably remains recessed and out of contact with the work surface during use thus reducing drag and wear. The surface working pad element (6) of the assembly is removably attached to the pad support element (1) so that by reversing the working pad both surfaces may be used. The mating of the raised portion (2) of the pad support element (1) into the aperture (7) of the working pad (6) enables the working pad (6) to be quickly and accurately mounted on a machine and prevents unwanted displacement of the pad (6) due to centrifugal forces, even during use in high speed rotary floor polishers or the like.

Abstract: A method and an apparatus detect the presence of and correct for timing misalignment between waveforms acquired by digital oscilloscopes. In a preferred embodiment, a digital oscilloscope (50) includes a waveform alignment system (60) that receives a first waveform (86) and a similar second waveform (88) of a periodic electrical signal. A digital signal processor (80) of the waveform alignment system generates an autocorrelation value in connection with the first waveform and a first cross-­correlation value in connection with the first and second waveforms and compares the values to determine whether they differ by more than a preselected tolerance, thereby to detect a timing misalignment between the first and second waveforms. Upon detection of a timing misalignment, the digital signal processor computes a shifted second waveform by changing the timing relationship of the second waveform relative to the first waveform and generates a second cross-correlation value in connection with the first waveform and the shifted second waveform. The digital signal processor shifts the second waveform relative to the first waveform such that the second cross-correlation value differs from the autocorrelation by less than the preselected tolerance, thereby to correct the timing misalignment.
