Patents by Inventor Christos Kinezos Ioannou

Christos Kinezos Ioannou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190260116
    Abstract: A wearable computing device can include a monopole-excited slot antenna formed by a gap between a housing (such as a highly conductive housing) and a bracket (such as a highly conductive bracket) within the highly conductive housing and by a back cavity between the highly conductive bracket and the PCB. The antenna configuration can include a monopole antenna electrically coupled to a printed circuit board and a slot antenna that is excited through coupled electromagnetic fields. The highly conductive bracket is positioned near a display window of the device, mostly below and partially enclosing a battery. The highly conductive bracket is positioned above the printed circuit board. This configuration allows for a relatively small dead band in the display window, a larger battery, compact and mechanically simple configuration, and superior water resistance.

  • Publication number: 20180294554
    Abstract: A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker. A housing with integrated antenna structures is also disclosed.
