    Abstract: An electromagnetic localization signal may be sensed by an electromagnetic field sensor in an in-vivo device with an electromagnetic field interference that is superimposed on the electromagnetic localization signal. The electromagnetic field interference may be filtered by outputting, by the electromagnetic field sensor, an alternating signal that represents, or in response to, the electromagnetic localization signal; sampling a first (e.g., positive) portion of the alternating signal during a first sampling window or period to obtain a first set of samples, sampling a second (e.g., negative) portion of the alternating signal during a second sampling window or period to obtain a second set of samples; and calculating a number, NR, from the first and second sets of samples, that approximately represents a substantially interference free electromagnetic localization signal.

    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: An in-vivo device includes a magnetic steering unit (MSU) to maneuver it by an external electromagnetic field. The MSU may include a permanent magnets assembly to produce a magnetic force for navigating the device. The MSU may include a magnets carrying assembly (MCA) to accommodate the permanent magnet(s). The MCA may be designed to generate eddy currents, in response to AC magnetic field, to apply a repelling force. The in-vivo device may also include a multilayered imaging and sensing printed circuit board (MISP) to capture and transmit images. The MISP may include a sensing coil assembly (SCA) to sense electromagnetic fields to determine a location/orientation/angular position of the in-vivo device. Data representing location/orientation/angular position of the device may be used by a maneuvering system to generate a steering magnetic field to steer the in-vivo device from one location or state to another location or state.

    Abstract: A wearable sensor belt used as a reference frame for determining a location of an in-vivo device in the gastrointestinal (GI) tract, the belt including N magnetic field generating coils and M magnetic field sensors configured for dynamic calibration of the belt's geometry in order to accommodate for dynamic changes in the shape and/or size of the belt from one subject to another, and for dynamic changes in the shape and/or size of the belt as a result of changes in a subject's posture. A method for localizing an in-vivo device swallowed by a subject using a sensor belt is also described.

    Abstract: A control circuit for controlling a state of a switching circuit may include a first unit to sense and interpret a wireless signal or physical parameter as an “on” signal to transition the switching circuit to the “on” state, or as an “off” signal to transition the switching circuit to the “off” state, and to transfer a first digital signal or logic value and/or a second digital signal or logic value, which may respectively or combinatorially represent the “on” signal or the “off” signal, to a second unit via a first output and/or a second output of the first unit, respectively. The second unit may force a control input of the switching circuit to a logic value which is a function of the first digital signal or value and/or second digital signal or value and congruent with the state to which the switching circuit is to be transitioned.
