20080278176	CALIBRATED S-PARAMETER MEASUREMENTS OF A HIGH IMPEDANCE PROBE - A new methodology for the measurement of the S-parameters of a high impedance probe allows obtaining a full two port S-parameter set for the high impedance probe. The measured probe S-parameters are then used for characterization of probes. An alternative method characterizes half of the fixture and termination as a one-port network and expanding it into a two-port error box. The two-port error box is then cascaded with the probe input.	11-13-2008

20110028864	Uterine sound device - A uterine sound device includes a first component having a handle and a stem, and a slidable member positioned around the stem. An inner wall of the slidable member fits around the stem such that the slidable member remains at a fixed position on the stem unless a predetermined amount of force is applied to the slidable member longitudinally along the stem. The stem includes graduated markings to indicate units of measure that are preferably formed of a non-leachable, biocompatible ink printed on the stem. In use, the sound stem is inserted past the cervix with the slidable member remaining on the outside of the cervix with insertion pressure causing the slidable member to slide along the stem toward the handle. The position of the slidable member according to the indicia indicates a depth into the uterus that the stem has reached.	02-03-2011
