    摘要： A fetal pulse oximeter sensor mounted on a sensor head with an articulating design. A lumen on one side of the sensor has a cable or rod therein to either push or pull that side of the sensor with respect to the main body, thus causing the sensor head to articulate. This can be used, for instance, to apply pressure against the fetus' scalp, with the sensor head, using the articulating mechanism, until an adhesive takes hold. Additionally, the sensor may be held in place on the fetus by an adhesive which is appropriate for a wet surface. The adhesive has the characteristics of having sufficient adhering characteristics to maintain the sensor in place, while at the same time not damaging the fetus' skin upon removal, without requiring suction.

    摘要： Method and apparatus for determining local impedance factors in an electromagnetic energy system for treating patients is disclosed. Respective measurement signals are sent through a patient treatment zone and a local impedance factor is estimated based upon the measurement signals. The estimated impedance factor is used to determine appropriate therapeutic levels of energy for patient treatment.

    摘要： A fetal sensor with a biasing mechanism for biasing the sensor against the fetus, with the biasing mechanism being automatically self-inflating and insertable in compressed form. The biasing mechanism in a preferred embodiment is a compressed foam or sponge which expands upon being exposed to fluid, such as amniotic fluid within the uterus. Thus, the biasing mechanism can be compressed to allow easy insertion, and then can expand once in place to provide the pressure needed to hold the sensor against the fetus.
