Gulu la ofufuza a Ben-Gurion University of the Negev ndi Weizmann Institute of Science (Israel) apanga njira () kuti akonzenso zokambirana zamkati ndi nyimbo pogwiritsa ntchito kugwedezeka kwa babu mu choyikapo nyali chokhazikika. Sensa ya electro-optical yomwe inayikidwa pamsewu idagwiritsidwa ntchito ngati analyzer ndipo, pogwiritsa ntchito telescope, inali yolunjika pa nyali yowonekera pawindo. Kuyeseraku kunachitika ndi nyali za 12-watt za LED ndikupangitsa kuti zitheke kukonza zowonera kutali ndi mtunda wa 25 metres.
Njirayi imagwira ntchito pa nyali yoyimitsidwa. Kugwedezeka kwa mawu kumapangitsa kusiyana kwa kuthamanga kwa mpweya, komwe kumayambitsa ma microvibrations a chinthu choyimitsidwa. Ma microvibrations oterowo amatsogolera ku kupotoza kwa kuwala kosiyanasiyana chifukwa cha kusamuka kwa ndege yowala, yomwe imatha kuzindikirika pogwiritsa ntchito kachipangizo kakang'ono ka electro-optical sensor ndikusinthidwa kukhala phokoso. Telesikopu idagwiritsidwa ntchito kujambula kutuluka kwa kuwala ndikuwongolera ku sensa. Chizindikiro cholandilidwa kuchokera ku sensa (Thorlabs PDA100A2 yochokera pa photodiode) idasinthidwa kukhala mawonekedwe a digito pogwiritsa ntchito 16-bit analog-to-digital converter ADC NI-9223.
Kulekanitsa kwa chidziwitso chokhudzana ndi phokoso kuchokera ku chizindikiro cha kuwala kwachidziwitso kunkachitika mu magawo angapo, kuphatikizapo , normalization, kuchepetsa phokoso ndi kuwongolera matalikidwe pafupipafupi. Script ya MATLAB idakonzedwa kuti igwire chizindikirocho. Ubwino wobwezeretsa mawu potengera magawo kuchokera pa mtunda wa mita 25 unakhala wokwanira kuzindikira mawu kudzera mu Google Cloud Speech API ndikuzindikira nyimbo zomwe zidapangidwa kudzera mu ntchito za Shazam ndi SoundHound.
Poyesera, phokoso linapangidwanso m'chipindacho pamtunda waukulu kwa okamba omwe alipo, i.e. phokosolo linali lokwera kwambiri kuposa kulankhula wamba. Nyali ya LED nayonso sinasankhidwe mwangozi, koma popereka chiΕ΅erengero chapamwamba kwambiri cha chizindikiro-ku phokoso (nthawi 6.3 kuposa nyali ya incandescent ndi nthawi 70 kuposa nyali ya fulorosenti). Ofufuzawo adafotokoza kuti kuchuluka kwa kuukira ndi kukhudzidwa kumatha kuonjezeredwa pogwiritsa ntchito telesikopu yayikulu, sensa yapamwamba kwambiri, ndi chosinthira cha 24- kapena 32-bit analog-to-digital (ADC); kuyesaku kunachitika pogwiritsa ntchito telesikopu yothandiza. sensor yotsika mtengo, ndi 16-bit ADC. .
Mosiyana ndi njira yomwe idakonzedweratu "", yomwe imagwira ndikusanthula zinthu zomwe zimanjenjemera m'chipinda, monga kapu yamadzi kapena phukusi la chip, Lamphone imapangitsa kuti athe kukonzekeretsa kumvetsera munthawi yeniyeni, pomwe maikolofoni yowonekera kuti ipangenso masekondi angapo olankhulira imafunikira kuwerengera mozama komwe kumatenga. maola . Mosiyana ndi njira zochokera ku ntchito kapena monga maikolofoni, Lamphone imalola kuti kuwukira kuchitidwe kutali, popanda kufunikira koyendetsa pulogalamu yaumbanda pazida zomwe zili m'malo. Mosiyana kuukira ntchito , Lamphone sifunikira kuunikira kwa chinthu chogwedezeka ndipo imatha kupangidwa mongokhala.
