Abstract: Methods and systems for electric propulsion are provided. An example method includes providing a magnetic shield using an accelerating channel made of a soft magnetic material; generating, by a magnetic system, a radial magnetic field in the accelerating channel to ionize a working substance, wherein the magnetic system includes a central magnetic pole, an outer annular pole, a magnetic circuit, and coils to carry an electrical current; and generating, using an outer hollow cathode and an anode-gas distributor disposed within the accelerating channel, an electrical discharge along the accelerating channel. The accelerating channel provides the magnetic shield to force the radial magnetic field to have a maximum gradient at a location of the central magnetic pole and at a location of the outer annular pole and to force ions of a working substance to pass isolators of magnetic poles, thereby decreasing erosion of the isolators.

Abstract: Methods and systems for a discharge power supply for providing a stabilized discharge power to a Hall-effect thruster are provided. A method includes sensing, by a first sensor circuit and based on a discharge power, a voltage sense signal, sensing, by a second sensor circuit and based on the discharge power, a current sense signal, multiplying, by a multiplying circuit, the voltage sense signal and the current sense signal to generate a feedback signal, generating, by a control logic circuit and based on control signals, further control signals, generating, by an impulse generation circuit and based on the further control signals and the feedback signal, control impulses, producing, by a transistor bridge and using the control impulses and a power source, an electrical impulses, and modifying, by an output circuit, the electrical impulses to generate the stabilized discharge power.

Abstract: An emergency communication system comprises at least two distributed servers. Each of the servers is an independently functioning device configured to operate cooperatively with another server, store personal data of users, duplicate data, and so forth. The servers are connected to a dispatch center, user devices of users, and personal devices of responders through two or more communications networks. The servers are further configured to implement a method including the steps of: receiving an alert signal initiated by a user during an emergency, determining a geographical location of the user based on the alert signal, identifying an emergency type associated with the user based on the alert signal, selecting at least one responder to address the emergency based at least on the emergency type and the geographical location of the user, and sending an emergency signal, including the geographical location of the user, to the at least one responder.

Abstract: An online event scheduler system for allowing users to find events of interest in which the users can participate and to allow users to set up impromptu meeting with nearby users.

Abstract: Methods and systems for providing earth observation (EO) data and analytics are provided. An example method may include providing EO images of geographical areas of a pre-determined size. The EO images can be associated with geographical coordinates and an EO data type. The method may include providing a user interface to configure a use case query. The use case query may include a use case geographical area and a use case EO data type. The method may include determining, based on the use case query, a subset of the EO images overlapping with the use case geographical area and associated with the use case EO data type. The method may include generating, by the analysis module and based on the subset of the EO images, a resulting EO image corresponding to the use case geographical area and displaying, via a graphic user interface, the resulting EO image.

Abstract: An intelligent search and interface customization system including innovative methods of processing user requests and optimizing search results is disclosed.

Abstract: An online system for managing multiple types of online sites for a company is disclosed. Such an online system is designed to retain user interest in the company.

Abstract: A method for executing a slots adventure game comprises the steps of displaying a virtual path for the slots adventure game and presenting to a player a first level (unlocked level) linked to the virtual path and subsequent levels (locked levels) linked to the same virtual path. Further, a selected slots game with the current quest task is initiated based on a player's selection. The player is then enabled to pass game levels by unlocking each of the subsequent levels sequentially.
