Abstract: An embodiment of the present application provides a temperature adaptive control circuit for a light emitting diode and a lighting and/or signaling apparatus. The control circuit includes: a light emitting diode load circuit unit in which one or more light emitting diodes are connected; and a temperature adaptive circuit unit comprising a positive temperature coefficient thermistor and a negative temperature coefficient thermistor connected in series, wherein the temperature adaptive circuit unit is configured such that current flowing through the one or more light emitting diodes in the light emitting diode load circuit unit is a function of sum of resistance of the positive temperature coefficient thermistor and resistance of the negative temperature coefficient thermistor. It not only can compensate the variation of the luminescent intensity with the temperature in a desired working temperature for the LEDs, but also can achieve overheating protection for the LEDs to avoid damage thereof.

Abstract: A torque converter includes an impeller, a turbine-piston hydrodynamically drivable by the impeller, and an annular lockup resistance member. The impeller includes an impeller shell. The turbine-piston includes a turbine-piston shell having a turbine-piston flange with a first flange surface facing an engagement surface of the impeller shell and an opposite second flange surface. The turbine-piston is movable axially toward and away from the engagement surface to position the torque converter into and out of a lockup mode in which the turbine-piston flange is mechanically locked to the impeller shell. The annular lockup resistance member is coaxially aligned with the rotational axis, fixedly connected and non-rotatable relative to the turbine-piston flange, and configured to resist axial movement of the turbine-piston flange toward the engagement surface and into lockup with the impeller shell.
