Definitions

  • the invention deals with a compact and autonomous infrared sensing apparatus.
  • An infrared apparatus comprises at least:
  • One of the drawbacks of this apparatus is that the photovoltaic device is spatially separated from the infrared detector and from the optical element.
  • the present invention has as its object to propose a compact and autonomous infrared sensing apparatus which does not present this drawback.
  • Another object is to provide an apparatus of the aforementioned type improved in an economical way.
  • the invention has as its subject matter a compact and autonomous apparatus of the aforementioned type, more particularly characterised in that said the optical element of the sensing apparatus is physically disposed so as to cover essentially the entire surface of the photovoltaic device, and :
  • FIGS 1A to 1K Schematic cutaway drawing of the basic design (fig 1A) of the apparatus according to the invention and of optional designs (fig. 1B to 1K) of the same apparatus.
  • Figure 2 Parts of an autonomous infrared sensing apparatus designed for a compact assembling according to the invention.
  • a compact and autonomous infrared sensing apparatus 1 can be seen in the figures 1A to 1K and 2.
  • This autonomous sensing apparatus 1 comprising at least:
  • An infrared detector 4 is a device which absorbs infrared radiation "B" and converts it to an electric signal.
  • a photovoltaic element is a device which absorbs incoming photons and converts them to electricity.
  • An optical element 5, according to the invention, is a device which at least transmits a part of the incoming electromagnetic radiation "A" to the infrared detector and to the photovoltaic device.
  • An electronic circuit 6, according to the invention is a device which transforms the primary electric signal of the infrared detector in a secondary electronic signal "S" used to activate another electric or electronic element.
  • the optical element 5 of the sensing apparatus 1 is physically disposed so as to cover essentially the entire surface of the photovoltaic element 3, and :
  • An autonomous sensing apparatus characterised in that part of the optical element 5 which has functionality in the infrared part of the spectrum deflects the incoming infrared radiation onto the infrared detector 4.
  • the part of the optical element 5 which acts as an infrared optical element is a part which at least deflects the incoming infrared radiation onto the infrared detector 4.
  • the infrared detector 4 is disposed on the active surface 3A of the photovoltaic element 3 (figures 1A and 1D to 1K).
  • the active surface 3A of the photovoltaic element 3 is the part of the surface of this element which absorbs photons and converts them into electricity.
  • the infrared detector 4 is placed in a cavity 3B in the active surface 3A of the photovoltaic element 3 (figure 1 B).
  • the infrared detector 4 is disposed behind the photovoltaic element 3 such that infrared radiation "B” reaches said infrared detector 4 through an aperture 3C (figure 1C).
  • a sensing apparatus 1 can be constructed which is compact.
  • the source of energy 2 also comprises at least one of the following :
  • a sensing apparatus 1 can be constructed which is both compact and autonomous.
  • the autonomous sensing apparatus 1 might comprise a peripheral housing 7 including a mirror 8 with the purpose of recapturing photons which have been reflected from the active surface 3A of the photovoltaic element 3, thus increasing the possibility of photon capture by the photovoltaic element 3 (figure 1E).
  • the autonomous sensing apparatus 1 further comprises an alarm device 9.
  • This alarm device 9 could be for example, a device which uses light or sound to draw attention (figures 1F and 1J).
  • the autonomous sensing apparatus 1 comprises a switching element 10 for another electric or electronic device 11 (figures 1G and 1I).
  • the autonomous sensing apparatus 1 further comprises at least a radio frequency emitter 12 for communication with a second electronic system 13 equipped with at least a radio frequency receiver 14.
  • the autonomous sensing apparatus 1 further comprises at least a radio frequency 12 emitter for communication with a switching element 10 equipped with at least a radio frequency receiver 14 (figure 1I).
  • the autonomous sensing apparatus 1 further comprises at least an infrared emitter 15 for communication with a second electronic system 13 equipped with at least an infrared receiver 16 (figure 1H).
  • the autonomous sensing apparatus 1 further comprises at least an infrared emitter 15 for communication with a switching element 10 equipped with at least an infrared receiver 16 (figure 1I).
  • the said second electronic system 13 is an alarm device.(figure 1J)
  • the autonomous sensing apparatus 1 further comprises at least one additional sensing device 17 for the infrared, ultraviolet or visible radiation (figures 1K and 2).
  • the autonomous sensing apparatus further 1 comprises an additional sensing device 17 for the measurement of temperature or humidity (figures 1K and 2).
