  • Patent number: 11872144
    Abstract: Skin patch sensors for monitoring and/or affecting body parameters, with alignment, positioning and attachment using magnets. The repeated use of releasable adhesive layers to retain skin patch sensors on skin can cause skin irritation, which can be reduced by rotating a skin patch between attachment times around a magnetically coupled pivot point. Skin patch sensors can be configured with internal coils to inductively couple to external power transmitting and communications coils with solenoids in anti-Helmholtz configurations.

  • Publication number: 20230241393
    Abstract: An electrode lead comprises an electrically insulative cuff body and at least three axially aligned electrode contacts circumferentially disposed along the inner surface of the cuff body when in the furled state. The electrode contacts may be circumferentially disposed around a nerve, and an electrical pulse train may be delivered to the electrode contacts thereby stimulating the nerve to treat obstructive sleep apnea. The electrical pulse train may be one that pre-conditions peripherally located nerve fascicles to not be stimulated, while stimulating centrally located nerve fascicles. A feedback mechanism can be used to titrate electrode contacts and electrical pulse train to the patient. A sensor that is affixed to the case of a neurostimulator can be used to measure physiological artifacts of respiration, and a motion detector can be used to sense tapping of the neurostimulator to toggle the neurostimulator between an ON position and an OFF position.

  • Patent number: 11630013
    Abstract: Pressure sensors having ring-tensioned membranes are disclosed. A tensioning ring is bonded to a membrane in a manner that results in the tensioning ring applying a tensile force to the membrane, flattening the membrane and reducing or eliminating defects that may have occurred during production. The membrane is bonded to the sensor housing at a point outside the tensioning ring, preventing the process of bonding the membrane to the housing from introducing defects into the tensioned portion of the membrane. A dielectric may be introduced into the gap between the membrane and the counter electrode in a capacitive pressure sensor, resulting in an improved dynamic range.
