 Virtual position markers for mobile mapping / 2448327
Disclosed engineering solutions are based on a technology through which a virtual position marker (e.g., a virtual pushpin or similar placeholder) is determined from query results. The virtual position marker corresponds to a first set of coordinates (e.g., latitude, longitude and/or altitude of an enterprise) for representing a point on the map. Various static and dynamic data can be used to select a result considered the most suitable from several query results. The virtual position marker can be output, for example, graphically displayed on map and/or used to provide audio instructions. Upon detection of changes in state, for example changes in the current position and/or changes in direction, speed, time, initial position or destination, the virtual position marker can be re-determined automatically, including changing the virtual position marker to correspond to a second set of coordinates now considered most suitable due to change in state.

 Method for widening magnetic field navigation application areas / 2447405
Magnitude of the Earth's magnetic field is measured on a profile from a movable carrier. Approximate coordinates on the carrier standard system are determined. Based on the approximate coordinates, maps of the reference Earth's magnetic field of a smaller scale or separate routes and/or topography and/or bathymetric data and/or maps for satellite altimetry on water bodies and/or maps of structural horizons (seismic, gravitating, electric), local geologic features, data on physical properties or rocks, theoretic, laboratory or experimental relationships between physical properties of rocks in a given area and/or region are selected. Using physical properties of rocks, the relationship between physical properties of rocks, the relationship between geophysical fields and geomagnetic sections in addition to rare data on the Earth's magnetic field, pseudomagnetic anomalies on the present geophysical fields and geologic bodies and sections are calculated. The observed field with all pseudomagnetic anomalies is corrected and those pseudomagnetic anomalies which correlate with the real field are selected. Using multiple regression, weight coefficients of different pseudomagnetic anomalies are calculated and these anomalies are summed up based on the weight coefficients. The obtained sum is mapped with the reference Earth's magnetic field of the section under investigation. Accurate coordinates of the carrier are determined by collating information obtained using an onboard system for measuring the Earth's magnetic field, with reference information on the field in the calculated pseudomagnetic anomalies.

A device consists of the walking stick with the fork and the wheel, comprising the mounted GPS receiver, and also provided with the fork turn drive. An output of the GPS receiver is connected with an input of the fork turn drive. EFFECT: use of the invention enables facilitating blind person's orientation. 4 cl, 3 dwg
The invention relates to the field of systems orientation. At the present time in the world practice for orientation of blind people used method, based on the technology of GPS navigation. Blind man gets sound tips on your location and the direction from the GPS navigation. Known for the development of a number of foreign companies in this area. In particular, Human Ware developed a system of orientation for the blind "Trekker 3", based on GPS technology. Using voice prompts that are generated in the GPS navigation system, blind people oriented, see the sites www.gisa.ru. and www.12v-clab.ru. The disadvantage of this method is the difficulty of the perception of the blind man audio cues while driving, in particular, expressed that it is necessary to count in mind the number of steps specified by the hint. This forces the blind man in motion always be in a concentrated condition for a correct understanding and implementation of voice prompts, which leads to fatigue and making mistakes. Another way orientation of blind people is a well-known method using a cane, which allows them to overcome obstacles and move on familiar routes. (See www.rgbs.ru, www.skbs.ru, "the glory of the white cane", Journal of The Our life, 2005, No. 11). But this method does not allow a blind person to navigate in unfamiliar surroundings. Usually satellite-based GPS navigation system and stick together are used for orientation of the blind man in space. As a prototype of the invention is selected both these methods. The aim of the present invention is to provide a process orientation, providing blind people comfortable movement on any unfamiliar routes using GPS technology and navigation device for its implementation. According to the invention, this objective is achieved in that on the lower end of a cane install the wheel, roll the stick on the wheel in front of him, producing the control signal by the orientation of the wheel information from the satellite navigation system GPS, run this signal turns the wheel and follow the stick in the direction of its motion. Diagram of the device for implementing the method is shown in Fig.1-3. Fig.1-3 shows: 1 - the blind man; 2 - cane; 3 - GPS receiver; 4 - pin plug; 5 - wheel; 6 - drive fork reversal; 7 - the second wheel; 8 - drive traction wheels; 9 - block speed control wheel. The method consists in the following. In order reed pointed out the blind man in the right direction in which prostranstve you must ensure that the movement of the stick in the desired direction. To do this, canes install the actuator pivot fork wheels, continuously measure GPS receiver the actual current location of the blind person and compare it to the digital map GPS receiver with the required route, which is pre-entered in the digital map. the error signal current and a given location serves to drive the fork reversal and turn your wheel in the desired direction. When driving it will move on a given route. Behind the wheel will move and the cane, followed by the blind man, which it rolls. Thus, driving from the GPS receiver spreads fork wheels mounted on sticks, provide movement along a given route that will allow the blind man, pushing the stick is easy enough to navigate in an unfamiliar area. Figure 1 depicts a blind man 1, which holds the reed 2. On canes 2 fixed GPS receiver 3. At the end of the stick 2 installed plug 4, which is fixed to the wheel 5. On the axis of rotation of the plug 4 has a drive reversal of the fork 6. Figure 2 shows the device, which entered the second wheel 7, identical to the first wheel 5 and mounted on the same axis of rotation with the first wheel. Figure 3 shows the device, which introduced the traction drive wheel 8 and is United with him and mounted on the handle of a cane 2 unit speed control wheel 9. The operation of the device shown in figure 1, is as follows. At the starting point of the blind man 1 enters in the GPS receiver 3 the end point of your route. Currently developed input devices for blind people in the GPS receiver. The GPS receiver 3 is paving the route of the blind person 1 in the set point. Then the blind man begins to move, pushing a stick 2, the end of which is installed the plug 4 with the wheel 5. During the movement of the GPS receiver 3 determines the actual current coordinates - latitude and longitude location of the blind person 1 and the direction of its movement and calculates the error current coordinates and the specified route, which paved the GPS receiver. the error signal Δ is supplied to the actuator pivot of the fork 6, resulting in the plug 6 turns the wheel 5, and outputs a cane, but for her and pushing her person on a given trajectory. Thus, any deviation from the trajectory will be compensated by rotating plug with 4 wheel 5. At the same time, the blind man does not receive any indication of the direction of motion, but simply follows the wheel 5, as for the Wrangler. In the device shown in Fig.2, the second wheel 7 is introduced to ensure greater sustainability canes 2 and more stable retention of the specified directions of the Oia when driving by increasing the grip. When the movement of the blind person 1 on a given route both wheels 5 and 7 simultaneously deployed in the desired direction when turning the plug 4, the actuator pivot of the fork 6. In the device shown in Fig.3, the blind person chooses the desired route, then use the block speed regulation 9 sets the desired speed and includes a traction drive wheel 8. After that, the device will start moving along a given route. Blind man 1, holding the upper end of the stick 2, will move followed her into the required destination point. The proposed device, the orientation of blind people, combining a GPS receiver and automatically controlled idler simplified and made more understandable to the blind man's interaction with the GPS receiver. In this case, the GPS receiver actually acts as a guide, asking tactile way the direction of movement of the blind person on a given route. Possibility of technical realization of the proposed method and device orientation for blind people is ensured by the following factors: 1. Currently already developed and used by the blind people GPS receivers using accurate digital maps. The accuracy of the method when using differential mode GPS system in which the MSC can be no worse than 1-2 meters. 2. The Electromechanical part of the device can be performed on existing small stepper motors. Calculations show that the mass of canes together with electronics can be no more than 1.5-2 kg The proposed method and the device can be used as a basis for the construction of a number of devices orientation for blind people. They allow you to implement easy-to-understand blind person communication interface with the system. This method and device can also be used for domestic satellite system GLONASS. In connection with the above, the author asks to grant a patent on the invention. 1. The way the orientation of blind people, namely, that on his cane install the wheel fork and the GPS receiver, which specify the coordinates of the route of the blind man, produce the coordinates of its current position, determine the error signal of the coordinates of the current and of the specified provisions and rolling up a cane, characterized in that the canes are installing the drive fork reversal and the control unit of the drive fork reversal, signal the error coordinates of the current position of the blind man and the specified route of its movement to the control unit of the actuator pivot fork and follow the stick in the direction of its motion. 2.
