    摘要: A system for cutting marine grasses, weeds and other plant life to protect a propeller drive watercraft is disclosed. An adjustable, protective cutting edge to protect a propeller, drive shaft of a boat or other watercraft motor is further disclosed. A propeller protection device to mount upon a watercraft is further disclosed for optimizing the navigation of watercraft and reducing in-piloting maintenance of clearing plant matter from a propeller of a watercraft.

    摘要: An implantable medical device includes a voltage measurement circuit to measure a potential difference between implanted electrodes in a thorax of a living being, the potential difference resulting from an electrical P-wave cardiac signal. The implantable medical device also includes a processing unit to calculate a vector corresponding to the P-wave cardiac signal, the vector comprising a magnitude and a direction, and derived from measured potential differences and orientations defined by locations of the implanted electrodes. The implantable medical device further includes a monitoring unit to track a rotation of the vector corresponding to the P-wave cardiac signal. In various implementations, the monitoring unit may use the rotation to detect an inter-atrial block condition.
