Granted Patent: Advanced Docking Stations

Apple has been granted a patent for a series of advanced docking stations for iOS devices such as their iPhone and iPad which have yet to be utilized. Apple's invention relates generally to docking stations which have planar like configurations and that operate in multiple orientations. Even more particularly, Apple's invention relates to improved techniques for transferring data and/or power between portable electronic devices and the docking stations.

In Apple's patent FIG. 13 we see a perspective diagram of a docking station which includes a base and a multi degree of freedom platform that is reminiscent of the swing arm styled iMac of 2002 in miniature. The platform (224) is coupled to an arm (226) via multi pivot joint (228) such as a ball and socket joint, and the arm is coupled to the base (222) via a second multi pivot joint (230) such as a ball and socket joint. Each of the joints 228 and 230 includes retention features for holding various positions and angles. Generally speaking, this arrangement allows the platform to yaw, pitch and roll as well as to translate in x, y and z. The user could therefore adjust the position of the platform to the best position for use. As shown, an iOS device like an iPad (14) is configured to be attached to the platform via magnets.

Technically speaking, opposing power transfer mechanisms are inductively based. The docking station includes a primary inductive coil and the iOS device is to include a secondary inductive coil that cooperates to form a two part transformer.

When the iOS device is docked, the complete transformer is created, i.e., the inductors are aligned along their axes and placed side by side without making electrical or mechanical contact. During power transfer, current is made to flow through the primary inductive coil. The resulting magnetic flux induces an alternating current through the magnetic field and across the secondary inductive coil thereby completing the circuit. The AC power received by the secondary inductive coil is converted to DC power for operating the iOS device and/or for storage in the battery.

Apple credits Steve Hotelling and Gus Pabon as the inventors of Granted Patent 7,916,467, originally filed in Q1 2010. Some of Apple's associated patents go all the way back to 2005 and so Apple doesn't have a valid excuse for not having inductive charging in play by now. Let's hope we see this come to market shortly.

Granted Patent: Antenna Isolation for iPhone, iPad

To satisfy consumer demand for small form factor wireless devices, Apple is continually striving to miniaturize the antennas used in their portable devices such as the iPhone and iPad. Apple's newly granted patent covers one suitable arrangement consisting of three antennas in the wireless communications circuitry.

The first and third antennas may be used to implement an antenna diversity scheme. With one suitable arrangement, a Wi-Fi transceiver that operates at 2.4 GHz and 5.1 GHz is coupled to the first and third antennas, whereas a Bluetooth transceiver that operates at 2.4 GHz is coupled to the second antenna. Antenna isolation elements that operate at 2.4 GHz may be placed between the first and second antennas and between the second and third antennas, thereby isolating the first antenna from the third antenna at 2.4 GHz and isolating the first and third antennas from the second antenna at 2.4 GHz.

Other Granted Patents Published Today

In June 2010 Apple was granted a patent for their fourth generation iPod nano. Today's granted patent D635,123 covers that very same design. In other industrial design news, China has granted Apple four registered designs for their Mac Mini under numbers 1002345.5M001 though to 5M004.  

Additionally, Apple has been granted a patent for their L-Shape MagSafe with LED. The cable connector design uniquely provides an assembly having a sticky film to shield a gap between an insulative housing and a cover. And finally, Apple has been granted a patent related to Web Clips.
