Gesture-based content sharing
A user selects a content item that he wishes to send. He then performs a gesture to specify a direction toward which the content item is to be sent. For example, he pretends to “throw” his portable communications device toward the West. To receive the content item, potential recipients also make gestures that specify receiving directions. For example, a recipient pretends to “catch” a ball thrown from the East. If the sending and receiving directions are compatible, then the content item is sent from the sender's device to the recipient's device. Enhancements to the basic scheme described above can be made to, for example, specify a dispersion angle for the sending or receiving directions or to include other restrictions so that, for example, only intended recipients can receive the content even if other potential recipients are in the specified sending direction and make appropriate receiving gestures. |

Circular polarized antenna structure
A circular polarized antenna structure is provided, including: an antenna having a main body, a protruding portion, and a stopping portion formed between the main body and the protruding portion; a base; a radiation conductor disposed on an upper surface of the base and having at least a first through hole formed above the via hole; a ground conductor disposed on a lower surface of the base and has at least a second through hole formed below the via hole; solder partially covering an end of the stopping portion opposing the main body and the first through hole; and colloid partially formed on the solder, the radiation conductor, and the upper surface of the base. The antenna penetrates the base, and the stopping portion abuts against the lower surface of the base, such that the antenna can be prevented from dropping due to the impact of an external force. |
