Abstract: A braking system for gymnastic machines having one rotating member, as a flywheel, on which magnetic braking members are arranged, and operating methods thereof. The system comprises a magnetic sensor for detecting the magnetic field intensity induced from the braking members on the flywheel, and a sensor for measuring the rotation velocity of the flywheel. The braking system comprises also a second magnetic sensor, arranged at a predetermined distance from the first magnetic sensor, to measure the magnetic field induced on the flywheel as conditioned by the structure of the gymnastic machine, and a temperature sensor, arranged in correspondence of the first magnetic sensor, to detect the temperature of the flywheel. The system comprises a control logic unit, operatively connected to the first and second magnetic sensor, to the temperature sensor and to the angular velocity sensor.

Abstract: A device for detecting proximity adapted to monitor a parking space, which has relatively small dimensions, is autonomous from the energy point of view even when positioned in the middle of the parking space and does not require the provision of stations outside the parking space to be supplied by photovoltaic cells. The architecture of the device is organized in such a way as to be able to keep almost all its components turned off, which are all turned on only when there is the need to detect whether the parking space is occupied or free and only for the time strictly needed to perform this operation. There is further disclose an architecture of a monitoring device adapted to communicate with a plurality of devices for detecting proximity, to form a system for monitoring parking spaces of a parking lot.
