Abstract: Papillary muscle position control devices (900) systems and methods are provided. According to an exemplary embodiment, a papillary muscle position control device generally comprises a first anchor (905), a second anchor (920), and a support structure (915). The first anchor can be configured to fixedly connect to an in situ valve of a heart ventricle. The second anchor can be configured to fixedly connect to a muscle wall of the valve. The support structure can be configured to have an adjustable length and be coupled to the first anchor and second anchor such that adjusting the length of the support structure varies a distance between the first anchor and the second anchor. Other embodiments are also claimed and described.

Abstract: High speed autofocus interferometric inspection systems and methods are discussed in this Application. In accordance with some embodiments, an inspection system can generally include a laser module, an interferometer module, and a system controller. The laser can produce laser pulses to excite a device such as a silicon wafer, chip capacitor or chip packaged/silicon die containing a plurality of solder bumps into vibration. The interferometer module can be disposed to receive reflected laser energy from the device to sense vibration displacements created in the device with the laser pulses. The system controller to receive vibration data from the interferometer, the system controller configured to output a control signal for adjusting a relative distance and position between the laser module and the device. Other aspects, features, and embodiments are also claimed and discussed.
