Abstract: A histotripsy therapy system configured for the treatment of tissue is provided, which may include any number of features. Provided herein are systems and methods that provide efficacious non-invasive and minimally invasive therapeutic, diagnostic and research procedures. The systems and methods herein are configured to measure and display forces acting upon the therapy treatment head during a procedure. In some aspects, buoyancy forces from the acoustic coupling medium are also accounted for.

Abstract: Implementations of enhanced content collaboration technology are disclosed herein. In an implementation, a list of users associated collaboratively with a shared document are ordered in a user interface based at least partly on their respective collaboration states with respect to the document. As their collaboration states changes, updates are received from a collaboration service and the list of users is re-ordered to reflect their updated collaboration states.
