Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to plastic surgery. Performing cuts in paraauricular areas, mobilizing skin flaps of face and neck, superficial musculo-aponeurotic system dissection, dissection in the layer under the superficial musculo-aponeurotic system, mobilization of the superficial muscle of the neck, movement, re-fixation of the cut out flaps of the superficial musculo-aponeurotic system of the face, excision of excess skin flaps and wound closure. Incisions in paraauricular regions are made by enclosing the hair growth line on the temple from the level of the upper edge of the auricle. Then tragus surface is passed into bovine and occipital areas, edging earlobes and auricle. Mobilization of skin flaps of the face and neck is performed to a vertical line that passes from the point of bilge arc intersection with the periphery of the circular muscle of the eye through anterior border of the masseter to the lower edge of the thyroid cartilage. Incision of the superficial muscular-aponeurotic system of the face is performed at distance of 2.5 cm from the tragus of the ear, parallel to the front edge of the masseter, from the level of the zygomatic bone to the upper edge of the thyroid cartilage, preserving the peripheral branch of the lower jaw of the facial nerve; horizontal skin incision 2 cm long in the sub-chin region at 1 cm from the chin protrusion, and Furnas's mandibular ligaments are transected. Cut out flaps of superficial musculo-aponeurotic system are moved in three vectors: first - in cranial direction and laterally at angle of 45 degrees in parotid-chewing area with fixation to front edges of lateral segments of superficial musculo-aponeurotic system. Second one is medial when interplatismal space in the sub-chin area is closed. Third one is lateral - when the subcutaneous muscle of the neck is sutured to the Laura fascia. 
     EFFECT: method enables excluding skin incisions in the temporal region in the scalp, reducing the volume of mobilized facial skin, optimizing the stability and quality of the aesthetic result, avoiding flattening of tissues in operated areas and stigma formation of "operated face".

Abstract: FIELD: power modules.  
     SUBSTANCE: invention relates to power modules based on bipolar transistors with an isolated gate. The transistor buffer creates the necessary current iG to recharge the gate capacity G. The additional circuit measures the voltage VEe, proportional to the current iC, released on the inductance LE and the resistance RE of the emitter output of the transistor. This VEe voltage is involved in the measurement of the collector current and in the formation of an error signal: a large emitter current. Also, the VEe is fed to the operational amplifier (OA), closing the current feedback. This is a safe current mode circuit: the more iC current, the less is the control signal at the gate. The second circuit of the safe mode is by voltage. The collector voltage Uc is fed to the OA through the differential circuit Cv, closing the feedback on the change in the voltage Uc. A rapid increase in voltage (usually when switched off) causes an increase in the gate voltage, tightening the front of the collector voltage growth Uc, while the piecewise linear approximation of the transistor model describes the saturation voltage as: Usat=Vo+(Ro+Temperature/K)*Ic, and the crystal temperature is calculated according to the dependence: Temperature = ((Usat-Vo)/Ic-Ro)*K+To.  
     EFFECT: expanding the arsenal of means for registering data on the operating mode of IGBT modules for generating signals for correcting the operating mode through a piecewise linear approximation of the transistor model when calculating the temperature, while the driver circuit is implemented in a controller that creates a reference Vref voltage for an operational amplifier that creates a control voltage at the gate of the transistor G.

Abstract: Изобретение относится к лифтовой механике, а именно к устройствам обеспечения безопасной эксплуатации лифтов. Устройство содержит ловитель с подвижной частью в виде двух самозаклинивающихся элементов и две тяги, связанные каждая со своим самозаклинивающимся элементом. В нормальном состоянии, т.е. когда канат ограничителя скорости (ОС) цел и натянут, тяги (3, 4) стянуты друг с другом за счет натяжения каната ОС. При этом вся система безопасности работает в классическом варианте, т.е. при срабатывании ограничителя скорости канат ОС тянет за собой обе тяги (3, 4) и срабатывает один из самозаклинивающихся элементов в зависимости от направления движения кабины. При обрыве или ослаблении каната за счет пружин тяги (3, 4) разводятся в разные стороны - верхняя тяга (3) вверх, а нижняя (4) вниз соответственно, увлекая за собой каждая свой самозаклинивающийся элемент (2). Самозаклинивающиеся элементы в свою очередь предотвращают движение кабины лифта как вверх, так и вниз. Изобретение обеспечивает повышение надежности всей системы безопасности лифта в целом. 4 ил.
