    Abstract: A helix antenna structure includes loop antennas and a multilayered printed circuit board including printed circuit board layers. Each printed circuit board layer includes a peripheral loop antenna and each adjacent two loop antennas are electrically connected by a connection bridge functioning as a monopole antenna. A selected printed circuit board layer physically and electrically accommodates a transmitter inside ‘its’ peripheral loop antenna, and it further includes a first antenna feeding line which is connected to the loop antenna that is disposed on the selected printed circuit board layer and electrically connectable to a first output terminal of the transmitter. A second antenna feeding line is disposed on another printed circuit board layer and electrically connected to its loop antenna and connectable to another output terminal of the transmitter. The two antenna feeding lines lie in a plane perpendicular to an axis of the printed circuit board after its folding.

    Abstract: A system for diagnosing an esophageal disease includes at least one processor and at least one memory storing instructions. The instructions, when executed by the at least one processor, cause the system to: access, during a procedure involving an in-vivo device located within a person, data measured by the in-vivo device relating to an esophageal disease; evaluate, during the procedure while the in-vivo device is located within the person, a diagnosis for the esophageal disease for the person by applying a trained machine learning model to the data measured by the in-vivo device; and communicate, during the procedure while the in-vivo device is located within the person, the diagnosis for the esophageal disease.

    Abstract: An ex-vivo communication module configured for communicating with a swallowable in-vivo device. The communication module comprises a receiving unit operating at a first frequency range and configured for receiving signals from the in-vivo device, and a transmitting unit operating at a second frequency range, different from the first frequency range and configured for transmitting signals to the in-vivo device. The transmitting unit is also configured for serving as a secondary receiving unit, receiving signals from the in-vivo device.

    Abstract: A patch includes: an adhesive layer configured to adhere to skin of a person, and a communication circuit that includes a current sensor and a resonant circuit. The resonant circuit includes a coil antenna and a capacitor. The current sensor is configured to sense current in the communication circuit over time, where the sensed current has a known relationship to current through the coil antenna. The patch further includes at least one of a circuit or a processor configured to at least perform: determining that a change in the current through the coil antenna is greater than a threshold change, and providing, based on the determination, an indication that the adhesive layer is at least partially detached from the skin of the person.
