Abstract
An electromagnetic (EM) probe for monitoring one or more biological tissues. The EM probe comprises a cup shaped cavity having an opening and an interior volume, a circumferential flange formed substantially around the cup shaped cavity, in proximity to the opening, at least one layer of a material, for absorbing electromagnetic radiation, applied over at least one of a portion of the circumferential flange and a portion of the outer surface of the cup shaped cavity, and at least one EM radiation element which performs at least one of emitting and capturing EM radiation via the interior volume.
Core Innovation
The invention relates to an electromagnetic (EM) probe for monitoring at least one biological tissue. The probe includes a dome shaped cavity having an opening and an interior volume, together with a circumferential flange formed substantially around the dome shaped cavity in proximity to the opening. The probe further includes at least one layer of a material for absorbing electromagnetic radiation, covering an inner surface of the circumferential flange.
The probe includes an emitting element configured for at least one of emitting and capturing EM radiation and electrically connected to at least one of an EM receiver and an EM transmitter. A location of the material on lateral walls and the inner surface of the circumferential flange is selected for contacting a skin of a subject in use when the EM probe is applied to the skin. The dome shaped cavity and the circumferential flange do not contact the skin of the subject.
The disclosed concept is supported by a construction in which EM radiation interfering with monitoring is absorbed by the EM radiation absorbing material at the flange region, while radiated and captured fields are limited to the dome cavity interior volume. The disclosure also describes arrangements where the emitting element is coupled to the interior volume, including optional dielectric substance filling and shielding and isolation associated with the flange and absorber layers.
Claims Coverage
The document provides two independent claims: one directed to an EM probe and one directed to a method of producing the EM probe. Across these independent claims, the coverage centers on a dome shaped cavity with an opening and interior volume, a circumferential flange near the opening, placement of an EM radiation absorbing material on selected flange/cavity regions for skin contacting without cavity/flange skin contact, and an emitting element electrically connected to an EM receiver and/or an EM transmitter.
Dome shaped cavity with opening and interior volume
A dome shaped cavity having an opening and an interior volume.
Circumferential flange near the opening
A circumferential flange formed substantially around the dome shaped cavity, in proximity to the opening.
EM radiation absorbing material on inner flange surface
At least one layer of a material, for absorbing electromagnetic radiation, covering an inner surface of the circumferential flange.
Emitting element electrically connected to EM receiver/transmitter
An emitting element configured for at least one of emitting and capturing EM radiation and electrically connected to at least one of an EM receiver and an EM transmitter.
Selected absorber location for skin contacting without cavity/flange skin contact
A location of the material on the lateral walls and the inner surface of the circumferential flange is selected for contacting a skin of a subject in use when the EM probe is applied to the skin, such that the dome shaped cavity and the circumferential flange does not contact the skin of the subject.
Producing the EM probe with dome cavity, flange, absorber, and emitting element
Providing a dome shaped cavity having an opening and an interior volume, including a circumferential flange formed substantially around the dome shaped cavity in proximity to the opening, applying at least one layer of a material for absorbing electromagnetic radiation over an inner surface of the circumferential flange, placing an emitting element configured for at least one of emitting and capturing EM radiation, and electrically connecting the emitting element to at least one of an EM receiver and an EM transmitter, with the material on the lateral walls and the inner surface of the circumferential flange placed for contacting a skin of a subject in use while the dome shaped cavity and the circumferential flange do not contact the skin of the subject.
Claim coverage is anchored in combining a dome shaped cavity with an opening and interior volume, a circumferential flange near the opening, at least one EM radiation absorbing material layer covering an inner surface of the flange and placed on lateral walls for contacting skin, while the dome shaped cavity and flange do not contact skin, and an emitting element emitting and/or capturing EM radiation electrically connected to an EM receiver and/or an EM transmitter. The method claim matches the same structural selection and contact constraint in the steps of producing the probe.
Stated Advantages
Reduces interference by absorbing electromagnetic radiation with the EM radiation absorbing material at selected flange/cavity locations.
Limits sensitivity to changes at the skin/environment by configuring the contact region such that the dome shaped cavity and the circumferential flange do not contact the skin of the subject.
Provides monitoring of at least one biological tissue using an EM probe with emitting and capturing EM radiation electrically connected to an EM receiver and/or an EM transmitter.
Documented Applications
Monitoring at least one biological tissue using the disclosed electromagnetic (EM) probe applied to a subject’s skin.
