Abstract: A system for monitoring the fetal size of an expectant mother comprises an acoustic sensor for positioning over the belly of the expectant mother, the acoustic sensor configured to receive an acoustic signal generated by the fetal heartbeat and to generate a sensor output signal. A fetal size is determined from a sensor output signal strength. This system is based on the realization that certain acoustic signals generated by the fetal heart beat are strongly correlated with the fetus size.

Abstract: A device is provided for monitoring the delivery and taking of medication pills by detecting both the passage of a pill and the covering of a pill outlet region, which is indicative of an active operation of the user to remove the pill from the pill outlet region. In this way, pill delivery can be monitored as well as an indication of actual pill taking.

Abstract: The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.
