  • Publication number: 20230314358
    Abstract: Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences.

  • Publication number: 20210399657
    Abstract: A device for recovering or dampening vibratory energy from a mechanical resonator, comprising: an electrical generator comprising an element for converting mechanical vibration energy into electrical charges coupled to the resonator, the electrical generator periodically transferring a portion of the electrical charges from one terminal of the conversion element to the other; a frequency variation to phase variation conversion device, comprising an injection-locked oscillator of which the free-running oscillation frequency is equal to the resonance frequency of the resonator, and supplying to the electrical generator a control signal of frequency equal to that of the signal outputted by the conversion element and of which the phase shift depends on the difference between the frequency of the signal outputted by the conversion element and the resonance frequency of the resonator.

  • Patent number: 11179599
    Abstract: A device for acclimatising at altitude comprising a breathing mask defining a confined air space when it is placed on the face of a user. The mask comprising a suction valve to let the surrounding air enter inside the confined space when breathing in; an expiration valve to let air exit with a determined resistance, so as to create an overpressurisation of air in the confined space, when breathing out; and a sensor to establish information about the pressure of the confined space behind. The acclimatisation device in addition comprises a unit for processing the pressure information configured to establish a breathing characteristic of the user and compare it to at least one target value, in view of recommending to them an adjustment of the breathing mode thereof.
