Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to dentistry, and can be used for dental implantation on the upper or lower jaw and depending on the results of determining the bone density of the jaw. Cone-beam computerized tomography (CBCT) of a patient's jaw is performed. Adequate location for the future implant, as well as metric dimensions of the "bone block" – a local fragment of the alveolar process, in the volume of which the future implant is to be located, as well as determining bone density, is determined. According to the results of CBCT, the doctor determines only the prospective anatomical site for the implant installation in the alveolar jaw. Thereafter, the X-ray and densitometry data are recorded in a computer program, which determines the most optimal bone block for implant installation and determines its metric dimensions depending on anatomy of adjoining elements – roots of teeth, vessels – and by specified parameters determines implant size – height and diameter, wherein quality of bone tissue is determined throughout the bone block and by schedules included into program, the pitch and depth of external thread of the implant surface is determined, thus, the computer creates a virtual model of the implant. Implant has a variable-pitch thread on the outer side, defined by a non-linear relationship between bone quality and pitch, and variable depth determined by non-linear relationship between thread depth and bone density. Program determines the maximum possible size of the implant to ensure its long-term functioning. Above model is checked by a doctor and sent in the form of a file to a machine with numerical program control for making the implant. After the milling operation, the surface of the implant is roughened and sterilized. Besides, based on the same parameters produced on the basis of CBCT and processed by the program, a surgical template is made with an accurate design entry point of the implant. 
     EFFECT: method enables to obtain an individual implant adapted for each patient due to the fact that the pitch and depth of the thread on the external surface of the implant vary smoothly in height in accordance with the density of bone tissue.

Abstract: FIELD: measuring equipment. 
     SUBSTANCE: invention relates to measurement equipment and can be used for measurement using differential sensor. Differential transducer comprises at least two transducers connected to common output of transducer and provided with possibility to supply excitation signals. To rectify the output signal of the sensor, a synchronous detector synchronized with the excitation signal and configured to generate a pair of quadrature signals is used. To carry out the measurement cycle, the sensor is simultaneously supplied with the first and second excitation signals which are antiphase. Using the registration device, values of the first quadrature signal pair are recorded at the output. Then supply of the first excitation signal is cut off while maintaining supply of the second excitation signal and the value of the second pair of quadrature signals is recorded at the output. Further, on the basis of the obtained values of the first pair, a scalar unbalance value of the sensor corresponding to the measured value is found. Values of the second pair are used to compensate for errors in finding scalar value of unbalance of the sensor. Measurement cycle is performed at least once. 
     EFFECT: reduction of measurement error of useful signal of imbalance of differential sensor intended for excitation with high-frequency antiphase signals.

Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to navigation, including radio navigation, and can be used to determine spatial coordinates (SC) of stationary or mobile radio object (RO). Method is characterized by that r/s with individual features is generated and transmitted by a ground post radio engineering system (PRES) including at least four ordered numbered points, the coordinates of the phase centres (PC) of the antennae of which are known on the RO. Besides, r/s is received and identified for each point on the ground control station (CS) with the mobile antenna (MA), the phase centre of the antenna (PCA) of which is moved along the specified straight-line trajectory according to the specified law of movement. At PCA fixed position, the frequency spectrum deviation (FSD) of the received r/s from its preset position for each point is measured. When moving the PCA, projections of the PC MA of its speed and acceleration are measured on straight lines connecting the PC MA with the PCA of the points, and based on these projections and movement speed of PC MA, time-varying transit times of r/s from PC MA to PCA of points are determined in accordance with proposed measurement equation. This information is transmitted to corresponding points, where information on FSD and time shifts are used, respectively, for frequency adjustment at each point and for general synchronization transmitted by all points of r/s. When receiving and identifying radio signals on the r/s at RO, relative ranges from the PCA RO to the PCA are determined, and from them and the well-known coordinates of the PCA of the PRES are unambiguously determined by the SC PCA RO. 
     EFFECT: technical result is absence, including requirements for availability of common time system for transmitting and receiving objects radio signals (r/s).

Abstract: FIELD: machine building. 
     SUBSTANCE: invention is intended for use in turbomachine building and can be widely used for reduction of vibration stress in blades of impellers of turbomachines. Vane blades of separate impeller of turbomachine are subjected to tensometry. Most dangerous resonance frequency of vibrations of the blades is determined, the effect of changing the geometry of the blade of the impeller to dangerous resonance frequency is calculated. Depending on the operating conditions, possible variations of the blade geometry are determined. Effect of such change of blade geometry on strength and rigidity properties of the blade is calculated. Optimum change is selected, which has less effect on reduction of blade life, which is laid in production technology of two types of blades, locally differing in geometry at span of tolerance for manufacturing of rated blade one to larger side, and second to smaller side, or two types of blades - of nominal shape and locally differing in geometry at span of tolerance for manufacturing of rated blade in larger or lower side. Then, for impeller with even number of blades, impeller blades of two types are made equally and arranged on impeller through one. For an impeller with an odd number of blades, two sets of blades of different types with an odd number of blades are made in any of the sets and placed on the impeller through one with arrangement in any one place of the impeller of two blades of an odd set in a row. 
     EFFECT: reduced vibration of blades of all turbomachine-type impellers, including mono-wheels, without artificial addition of additional circumferential non-uniformity in temperature field and without complication of turbomachine control system, which, as a result, reduces overall level of vibrations, improves reliability and service life of turbomachine as a whole.
