Title: Digital frequency monitoring
Inventor: BRACMARD GAETAN J J
IPC: H03K5/1252
Filed: 2000-10-17
Abstract: A pulse monitoring circuit monitors the pulse length of both the logic high pulse (11) and logic low pulse (15) of a received digital sequence. The pulse lengths are compared with a preferred transition window, and if the pulses transition are within the preferred transition window then they are categorized as good pulses. The pulse monitoring circuit issues an enable signal only when at least two consecutive good pulses are received. The pulse length is determined by means of a reference voltage (Vref), a first faster linear voltage ramp (35, 45), and a second slower linear voltage ramp (31, 41). The two linear voltage ramps are initiated in response to a logic change of the received digital sequence and continue to raise their outputs until the received digital sequence changes state once again. The values of the two linear voltage ramps at the time of the second state change are compared with the reference voltage. If the faster linear voltage ramp is above the reference voltage and the slower linear voltage ramp is below the reference voltage, then the observed pulse of the digital sequence is determined to have transitioned within its preferred transition window.

Abstract: Phase locked loops are described which handle momentary break in an input communication channel. The phase locked loops provide the capability to "hold" the output clock in a communication system at or very near the last output frequency before the loss of input data. The phase locked loops according to the teachings of the present invention include a differential phase detector that receives an input signal and feedback signal and produces a different output signal. An electronic selector circuit is coupled to a differential output of the phase detector with an input that is responsive to a detected state of the input signal. An operational amplifier based loop filter circuit is provided in the phased locked loop. The electronic selector circuit provides the differential output of the phase detector at a pair of inputs to the operational amplifier. A voltage controlled oscillator is coupled to an output of the operational amplifier and provides an output frequency for the phased locked loop circuit. The electronic selector circuit is operable to control the input to the operational amplifier to hold an output frequency of the voltage controlled oscillator at a substantially constant frequency.

Abstract: This invention relates to novel airbag coating compositions and systems comprising pre-expanded or non-expandable microspheres that provide effectiv e insulation for the target airbag fabric during exothermic inflation. The inventive airbag fabrics are either pre-calendered prior to application of this composition or are coated through a gap (floating) knife method with su ch heat-expandable microsphere-containing compositions. The coated airbag fabri cs and cushions may then be heated to evaporate the solvent within the coating composition. The resultant fabric thus exhibits the presence of the microsphere constituents of the coating compositions both within the interstices between the individual yarns of the fabric and over the raised yarns of the fabric. Such a coating system thus provides an extremely high degree of protection from heat exposure that permits structural integrity of  the target airbag cushion airbag and provides protection from such high inflation temperatures to a vehicle passenger cushion during such a highly exothermic inflation event. The method of forming such specific airbag coati ng systems on airbag fabrics is also encompassed within this invention.

Abstract: L'invention concerne une bride de serrage d'un dispositif de serrage de plaque réfractaire dans un appui d'une vanne coulissante d'une installation de coulée. Ladite bride est dotée, d'une part, d'une zone de poussée sur laquelle une force de serrage peut s'appliquer de façon à pousser la bride contre une plaque réfractaire placée sur l'appui et, d'autre part, de deux extrémités, chacune pouvant s'appliquer contre une arête de la plaque réfractaire. La bride de serrage se caractérise en ce qu'elle peut se déformer élastiquement, que chacune de ses extrémités est conformée de façon à reposer sur l'arête correspondante de la plaque réfractaire lorsqu'une force de serrage est appliquée à la bride, et que cette dernière est également déformée de façon à également reposer sur la paroi du siège sous l'effet de la dilatation de la plaque ou d'une force de serrage plus grande. La bride de serrage est intéressante notamment parce qu'elle s'adapte automatiquement à la géométrie de la plaque qu'elle doit immobiliser, ainsi, les variations de formes entre les plaques, du fait de leur procédé de fabrication, n'engendrent aucun problème de serrage.
