Vorbeam saptamanile trecute despre posibila implementare a unui sistem de incarcare inductiva pentru iDevice-uri si iata ca Apple breveteaza o astfel de tehnologie. In imaginile de mai sus avem produsul conceput de catre Apple pentru incarcarea prin inductie a dispozitivelor noastre insa intregul sistem nu functioneaza chiar atat de grozav. Teoretic ar trebui sa avem de la Apple un dispozitiv care ar incarca iDevice-urile fara fir insa Apple propune un sistem care ar utiliza castile dispozitivelor pentru a face incarcarea. Castile ar trebui conectate la un nucleu feromagnetic pe care il avem reprezentat mai sus montat pe dispozitiv. Acest nucleu ar forma un flux magnetic in jurul dispozitivului iar iDevice-urile ar trebui sa se poata incarca fie cu ajutorul castilor fie prin aer. Presupun ca utilizarea castilor asigura o incarcare mai rapida decat incarcarea fara fir altfel nu prea inteleg de ce sunt ele prezente acolo.
Apple’s invention relates to a technique for inductively charging an electronic device which involves winding an audio cable for the electronic device around a charging mechanism multiple times so that one or more conductors in the audio cable form an inductive receiving coil. Next, a magnetic field is created through the charging mechanism to induce a current in the inductive receiving coil. Finally, the induced current in the inductive receiving coil is used to charge a rechargeable battery for the electronic device.
Ideile prezentate de catre Apple aici probabil nu vor fi vreodata implementate intr-un produs si reprezinta, spun eu, o metoda de a distrage atentia celor interesati de tehnologiile companiei. Ultimele zvonuri privind incarcarea inductiva sustineau ca Apple va lansa un sistem asemanator cu cel oferit de catre HP prin Touchstone. Totusi incarcarea inductiva nu va ajunge in iDevice-uri mai devreme de anul 2012 pentru ca iPhone 5 nu va avea asa ceva iar iPad 3 este inca prea aproape pentru Apple deci poate incepand cu iPhone 6 vom vedea un asemenea dispozitiv vandut de catre Apple.
In some embodiments, after winding the audio cable around the charging mechanism, the technique further involves electrically coupling a first contact, which is coupled to the one or more conductors in the audio cable, to a second contact associated with the electronic device to complete a circuit between the inductive receiving coil and the electronic device.
In some embodiments, the first contact is located on a first earphone (e.g., an earbud) which is attached to the audio cable. In a further variation, the first contact is conductive metal mesh screen that also protects a driver for the first earphone.
