Patent CA-2175853-C (CA)
Inventor: KOS RICHARD JAMES
IPC: H04Q11/06

Abstract: A high speed time multiplexed switch (TMS) fabric unit for use in a telecommunications  system having relatively low speed TMS access links. To receive signals from the low speed access links, the TMS fabric unit of the invention consists of a plurality of programmable multiplexers where each programmable multiplexer is connected to a predetermined number, J, of the access links. Eachaccess link carries M time slots where M is a relatively large number, i.e. 100. The programmable multiplexers put the content of the access links onto two high speed links. The speed of the high speed links is at least J times the speed of the access links such that for each time slot on the access links there is a fixed group of at least J time slots on each high speed link. Each of the two high speed links deliver the signals to at least one high speed TMS fabric where the speed of the high speed links is matched to the reconfiguration rate of the high speed TMS fabric. To transmitsignals from the high speed fabric to the low speed access links, the above-described arrangement is essentially duplicated in that two high speed links connect the high speed TMS fabric to programmable demultiplexers. The programmable demultiplexers deliver the content of the fixed group of J time slots on the high speed links to J access links. The TMS fabrics are non-blocking space division switches between the high speed links coming from the programmable multiplexers and the programmable demultiplexers.

Abstract: Methods (70, 100, 150) efficiently as-sign user channels in a LEO (low-earth or-bit) telecommunication system (10). These methods (70, 100, 150) adapt the channel reuses based on system load or demand. These methods (70, 100, 150) achieve high capacity and minimize interference for the particular situation. Since these methods (70, 100, 150) are adaptive, they adjust to maintain efficient operation as the load con-ditions change.

Abstract: La présente invention concerne un stimulateur cardiaque bi-cavité destiné à  réguler l'intervalle de l'échappement auriculo-ventriculaire afin d'optimiser la synchronisation des impulsions de stimulation ventriculaire délivrées dans le cadre d'une thérapie pour des patients atteints de myocardiopathie. Le système de stimulation effectue une surveillance continue afin de déterminer l'instant où une impulsion de stimulation délivrée donne une onde de fusion, et règle périodiquement l'intervalle d'échappement auriculo-ventriculaire en fonction du pourcentage ou du taux de survenue de telles ondes de fusion.  Selon un mode de réalisation spécifique, le système de stimulation détermine le pourcentage d'impulsions de stimulation ventriculaire délivrées suivies d'une onde de fusion par rapport à un nombre prédéterminé d'intervalles, et diminue l'intervalle d'échappement auriculo-ventriculaire si ce pourcentage n'est pas inférieur à un minimum prédéterminé. Le système de stimulation augmente aussi régulièrement l'intervalle d'échappement auriculo-ventriculaire lorsque le taux d'ondes de fusion est acceptable, ce qui revient à réaliser un système en boucle fermée permettant de maintenir la longueur de l'intervalle auriculo-ventriculaire à une valeur optimale acceptant de façon maximale la détection complète des impulsions de régulation ventriculaire délivrées. Selon un autre mode de réalisation, la régulation de l'intervalle d'échappement interventriculaire d'un stimulateur cardiaque fonctionnant en mode sans suivi vise à optimiser l'excitation préalable du ventricule.

Abstract: A reclosable fastener assembly having two interlocking profiles with uppermost closure elements and bottommost closure elements and a slider for moving between a closed position and an open position along the profiles in straddling relation. The slider has a top and side walls depending from opposite sides of the top for receiving the profiles therebetween. The side walls extend downward from the top to a point at or below the profiles, and the side walls extend from a separating end of the slider to a pinching end.  The side walls have a greater spacing at the separating end than at the pinching end, but close enough at the pinching end to press the first and second profiles into an interlocked relationship as the slider is moved toward the closed position. The slider has a separating leg depending from the top between the first and second side walls at the separating end of the slider.  The separating leg is inserted past at least one of the uppermost closure elements of the profiles, but not between the bottommost closure elements. In a second aspect, the fastener assembly includes means for holding the bottommost closure elements in interlocked relationship when the slider is in the closed position, such that the bottommost closure elements are in interlocked relationship throughout their entire length.

Title: Method of impregnating a mineral fiber insulation batt with extruded synthetic fibers
Inventor: CHURCH JOSEPH T
IPC: B29C47/02
Filed: 1998-07-21
Granted: 2002-02-12
Abstract: A method of directing extruded synthetic fibers toward at least one surface of a mineral fiber insulation batt, and corresponding apparatus and resulting product.  In certain embodiments, a row of extrusion heads is provided for directing extruded synthetic fibers (e.g. fibers including ethyl vinyl acetate or EVA) toward a surface(s) of the batt(s) to be impregnated with same.  Optionally, extrusion heads may be provided all around the batts so as to impregnate substantially all surfaces thereof with the extruded synthetic fibers.  As the fibers exit the heads, they are hit with pressurized heated air streams which cause them to go into an insipid spin which increases directional tensile strength of the resulting batt in all directions.  In certain embodiments, every other batt of a plurality of batts passes over an elongated member which extends over top of the conveyor in order to more efficiently impregnate edge surfaces of the batts.

Abstract: In a device for winding coils from at least two parallel guided winding wires in axial grooves arranged on the outer circumference of rotationally symmetrical bodies of electric equipment and for looping the winding wires around two contact hooks that are annularly arranged on the end surface of the body and separated from one another, the winding wires are inserted into the grooves by a winding arm that can be turned about a rotational axis (y) which lies perpendicular to the rotational axis (x) of the body. A wire guide with separated wire outlets for the two winding wires is arranged on the free end of the winding arm. The wire guide can be turned between a winding position in which the winding wires adjoin one another in essentially parallel fashion so as to insert the wires into the grooves, and a looping position, in which the winding wires are spread apart so as to loop the wires around the contact hooks.

Title: Electrical machine with a single pole winding
Inventor: HILL WOLFGANG
IPC: H02K1/14
Filed: 1997-10-15
Granted: 2005-02-08
Abstract: Electrical machines with a radial air gap field, especially low-power EC dead-end feeders, having the advantage of individually wound poles.      The trapezoidal cross section of the slot and small slot openings in the direction of the air gap make it difficult to produce a compact winding.      According to the invention the body of the electric machine which forms the individual poles is made of soft magnetic segments. The segments are preferably made of axially stacked metal sheets having indentations on the edges forming the wall of the slot. This enables the conductor wire to be guided in a precise manner during the winding of individual poles.      At the air gap the pole shoes cover almost all of the perimeter and at the opposite end they form adjacent pole segments, preferably recesses in which retention pins, once mounted, are inserted axially and ensure radial fastening. In multiphase machines wound and unwound T-segments alternate it the direction of the width of the slot. X-segments have a pole surface which is fractionally increased according to the number of phases.  The invention enables highly efficient electric drive units to be produced at low cost.
