Abstract: The invention relates to a method for calculating a stimulus for the change of shape of a medical aid in order to change the position of the medical aid from an actual position to a final target state. In order to achieve optimized treatment for the patient, a method comprising the following steps is provided: Detecting the actual position of the body part to be corrected after a first correction step in a control unit, Comparing the actual position of the body part to be corrected with a target position that is stored in the control unit, If applicable, detecting, by the control unit, the deviation between the actual position and target position of the body part to be corrected, Calculating with the control unit the stimulus that has to act on the medical aid to perform a second correction step, taking into account the deviation between the actual state and target state of the body part to be corrected, wherein the effect of the stimulus on the medical aid is saved in the control unit.

Abstract: The present disclosure relates to a method for carrying out an orthodontic intervention, using a set of orthodontic correction devices, with the aim of transferring via the correction devices at least part of the teeth from an actual position into a corrected target position, and employing several steps (S1, S2, S3, S3?, S4, S5), each correction device being associated with at least one step. In two subsequent steps (S3, S3?) two correction devices (1; 2), which have a substantially identical shape, are used.

Abstract: The invention relates to a method for the repeated activation of orthodontic correction devices with a known critical temperature (Tkrit) and a glass transition temperature (Tg) lying above the critical temperature. In the method according to the invention, in order to guarantee gentle repeated activation, an orthodontic correction device is heated to a temperature that lies above the critical temperature but below the known glass transition temperature. The invention also relates to a device for performing the method.

Abstract: A contactor for an air temperature and humidity control device is provided including a plurality of contact modules. Each contact module has a generally porous sidewall configured to define an internal space through which a hygroscopic material flows. A first airstream passes over a first portion of the plurality of contact modules. A second airstream passes over a second portion of the plurality of contact modules.

Abstract: A contactor configured for use in a dehumidification system is provided including a plurality of contact modules. Each contact module has a porous sidewall that defines an internal space through which a hygroscopic material flows. Adjacent contact modules are fluidly coupled to form a multipass flow path for the hygroscopic material through the contactor.

Abstract: A contactor configured for use in a dehumidification system is provided including a plurality of contact modules. Each contact module has a porous membrane that defines an internal space through which a hygroscopic material flows. A membrane property of the porous membrane of at least one contact module is substantially different than the other membranes of the plurality of contact modules.

Abstract: An air temperature and humidity control device is provided including a first heat pump having a compressor, an expansion valve, a condenser, and an evaporator. The first heat pump has a refrigerant circulating there through. A humidity controller includes a first contactor fluidly coupled to the evaporator and condenser. The first contact includes at least one contact module having a porous sidewall that defines an internal space through which a hygroscopic material flows. A first air flow is in communication with the porous sidewall of the first contactor. The device also has a second heat pump including a first polishing coil. The first polishing coil is substantially aligned with and arranged generally downstream from the first contactor relative to the first air flow.
