  • Patent number: 8863908
    Abstract: A movement of an elevator cage is detected by an elevator control on the basis of signals of a rotary encoder, coupled with a rotational movement of the drive motor or the drive pulley. Before movement of the cage begins, a movement plot in the form of a trip/speed profile is calculated for travel of the elevator cage from an instantaneous elevator cage position to a destination stopping point position. An anticipated slip between the drive pulley and a support means is included in the calculation of the trip/speed profile, and during the travel of the elevator cage a rotational movement of the drive motor and thus of the drive pulley is controlled by the elevator control in dependence on the calculated trip/speed profile and on signals of the rotary encoder.

  • Patent number: 8829802
    Abstract: In order to keep the advantage of PWM dimming control scheme and make the LED driver high reliability and the LED lamp long lifetime, it is required that the frequency of PWM dimming control scheme is related with or the same as the output frequency of existed dimmers; and the output PWM dimming pulse is covered by the output pulse from dimmers further. The present invention discloses a novel “LED dimming control” scheme to make that the frequency of PWM dimming control scheme is related with or the same as the output frequency of dimmers; and the output PWM dimming pulse is covered by the output pulse from the dimmers further. In this way, it can guarantee that as PWM dimming pulse comes, the output from the dimmer can offer enough power to the LED driver and the LED driver can output the required LED driving current without flicker.

  • Patent number: 8629670
    Abstract: A switching adapter control method for adaptive mobile power systems is composed of reference current generator, current mode error compensator, controllable constant turn-off timer, PWM generator and MOSFET driver. The output of the switching adapter can show constant current and voltage characteristics, that means, as the DC bus voltage is over a preset voltage, the adaptor's output characteristic is converted from a constant current source into a constant voltage source with the preset voltage. For low output capacitance case, the present invention has the ability to smoothly reduce the switching frequency of the switching adaptor and reduce the switching losses and meet Energy Star 2.0 requirements under different load conditions. And the output ripple current and voltage can be in the allowed range.
