Patent №2247047: SYSTEM OF AND METHOD TO CONTROL SHUNTING OPERATIONS IN ELECTRIC DEPOT OF MONORAIL TRANSPORT SYSTEM

Patent №2228278 – THE CONTROL SYSTEM OF ELECTRIC SUBSTRUCTING COMPOSITIONS OF MONORELS TRANSPORT SYSTEM AND METHOD OF CONTROLLING OF A MONORELIC TRANSPORT SYSTEM USING THE AUTOMATED SYSTEM

FIELD: railway transport; signaling and communication.
SUBSTANCE: proposed group of invention relates to railway automatic controls and is designed for shunting of electric trains and complies with specific requirements to monorail transport system. Electric depot of monorail transport system consists of outer and inner parking tracks for electric trains before entrance and exit gates and inside depot and also transborder. Control line contains digital computer complex connected by communication lines with stationary and mobile control objects outside and inside depot and furnished with subscriber devices and transmit-receive antenna distributed along parking tracks and make in form of radio radiating cables, and stationary and mobile control objects state pickups, stationary and mobile devices generating control signals and system to determine position of electric trains. Stationary control objects are assembled into device representing mimic diagram of depot, alarm bell drive, gate andtransborder drives, light signals. Mobile control objects are grouped in electric trains, on parking tracks outside and inside depot and on transborder. Stationary devices for generating control signals are grouped in workstations with stationary control panels, and mobile control signal generating devices, in carry-on remote control panels of depot operator on duty and control cabin of electric train. Stationary control objects, state pickups found of said objects, workstations and system to determine position of electric train are connected with computer complex by wire and/or wireless communication lines by means of access units, and mobile control objects are connected with computer complex by wireless communication lines through access units. Method to control shunting operations in electric depot of monorail transport system includes three steps: receiving of electric train at depot from route of monorail transport system, departing of electric train from depot to route of monorail transport system and re-positioning of electric train inside depot. Depot dispatcher, operator on duty and electric train driver are engaged in said operations.
EFFECT: improved shunting in depot of monorail transport system owing to optimization of control

The disclosed controlled preselector provides bandwidth consistency with variation of the tuning frequency thereof, identical input resistances at both the inverting and non-inverting inputs and is characterised by low input resistance.

Patent №2676013C1: DIGITAL BROADCASTING EMITTED RADIO SIGNAL POWER AMPLIFICATION METHOD AND DEVICE

FIELD: radio engineering and communications.
SUBSTANCE: claimed invention relates to the digital broadcasting emitted radio signal power amplification methods and devices. In the invention using the channels orthogonal frequency division, the digital signals OFDM conversion into the analog signal, its amplification to the required power and radiation, wherein in the process of the OFDM signal generation, performing its peak factor reduction in the certain sequence: first, implementing the reserve carriers method, and then applying the active constellation adaptive expansion algorithm for the OFDM signals peaks region conversion, and using the regenerative power supply unit, which accumulates energy in the pauses between the signals peaks.
EFFECT: technical result of the invention is a significant increase in the radio signals radiation efficiency on the transmitting side, increase in the transmitter energy efficiency and reliability, amplified signals dynamic range expansion without increase in the power supply unit power, nonlinear distortions reduction.

Patent №2697823: THE METHOD OF WARNING THE POPULATION; THE SYSTEM OF WARNING THE POPULATION; IMPLEMENTATION OF THIS METHOD AND A RADIO DEVICE FOR THIS METHOD IMPLEMENTATION OF THE POPULATION WARNING

FIELD: radio engineering, communication.
SUBSTANCE: The invention refers to radio broadcasting systems for targeted public emergency notification. The technical result is an increase in the accuracy of the targeted public alert and the probability of alerting people in an emergency area. This technical result is achieved through the use of an established broadcast network of powerful radio transmitters to transmit the warning signals; the broadcast of the warning signals is carried out from the same radio transmitters and in the same frequency range as the main broadcast, which guarantees equivalent conditions for both the radio warning signals and the main broadcast signals. The use of FM RDS technology in the short pause of the main broadcast for the transmission of activation messages to activate radio receivers that are in standby mode allows to solve the problem of remote activation of radio receivers.
