Abstract

The disclosed systems and mobile electronic devices may include a capsule that houses various electronic components. These systems may also include a cradle that is configured to removably couple with the capsule. Still further, these systems may include a strap connected to a first end of the cradle. The strap itself may include at least one antenna. The systems may also include a radio frequency (RF) transparent interconnect that electrically connects the antenna in the strap to at least one of the electronic components in the capsule. Various other methods of manufacturing, systems, and apparatuses are also disclosed.

First claim

What is claimed is:

1 . A system comprising:
a removable capsule that houses one or more electronic components; a cradle that is configured to removably couple and uncouple with the removable capsule via a movement that includes at least one of a twist, a turn, or a rotation of the removable capsule; at least one strap connected to at least a first end of the cradle, the strap including at least one antenna electrically coupled with a first end of a capacitive connector; and a radio frequency (RF) transparent interconnect on the removable capsule, the RF transparent interconnect comprising an RF transparent opening through which the first end of the capacitive connector of at least one antenna in the strap forms a capacitive connection with a second end of the capacitive connector located within the removable capsule in response to the cradle being coupled with the capsule via the movement, wherein the second end is electrically connected with at least one of the electronic components within the removable capsule.

2 . The system of claim 1 , wherein the RF transparent interconnect avoids contact with or travel through the cradle.

3 . The system of claim 1 , wherein the capacitive connection via the RF transparent interconnect is established through an RF transparent material of the RF transparent interconnect that is configured to allow transmission of or reception of RF electromagnetic signals between the first end of the capacitive connector and the second end of the capacitive connector.

4 . The system of claim 3 , further comprising an impedance matching circuit electrically positioned between the second end of the capacitive connection and one or more transmission lines to the one or more electronic components.

5 . The system of claim 3 , wherein the capacitive connection includes one or more capacitive elements, and wherein the one or more capacitive elements are coated in an RF transparent coating, and wherein the cradle is configured to removably couple and uncouple with the removable capsule via an aligning mechanism that includes one of a pin or a magnet to align the first end of the capacitive connection with the second end of the capacitive connection responsive to the movement.

6 . The system of claim 1 , wherein the at least one strap further includes one or more sensors.

7 . The system of claim 6 , wherein the one or more sensors and the at least one antenna included on the at least one strap share at least a portion of conductive trace material.

8 . The system of claim 6 , wherein the one or more sensors in the strap comprise electromyography (EMG) electrodes.

9 . The system of claim 1 , further comprising a second strap connected to a second, different end of the cradle, the second strap including a second antenna.

10 . The system of claim 9 , wherein the at least one antenna of the at least one strap and the second antenna of the second strap function together to form a dipole antenna.

11 . The system of claim 1 , wherein the cradle further includes a printed circuit board (PCB) comprising one or more electronic components.

12 . The system of claim 11 , wherein the one or more electronic components of the PCB on the cradle are electrically connected to the electronic components of the capsule upon coupling the capsule to the cradle.

13 . The system of claim 1 , wherein the at least one strap is interchangeable with a second strap, and wherein the second strap includes a different antenna than that included in the at least one strap.
