Abstract: The present disclosure generally relates to systems and methods for generating termination notification of an experiment to be presented through a user interface. In some implementation examples, a termination notification system generates a probability value that is valid as of a time period of an experiment at a predetermined point in time based on at least data sample obtained during the time period, predicted sample sizes of each time period of the experiment, or probability values generated prior to the time period. Responsive to determining that the probability value that is valid as of the time period satisfies a threshold value, the termination notification system causes the user interface to present the termination notification that, when selected, causes the experiment to terminate prior to completion of a predicted duration of the experiment.

Abstract: A 3D metal printing machine or apparatus includes a welder that deposits one or more layers of metal, and a powered cutting tool that may be utilized to remove a portion of the metal deposited by the welder after the metal has solidified. Numerous layers of metal can be deposited and machined to form complex 3D metal parts. During fabrication, a part may be formed on a support whereby the part can be fabricated by welding and machining operations without removing the part from the support. A 3D CAD model of a part may be utilized to generate code that controls the 3D metal printing apparatus. A measuring device such as a probe or laser scanner may be utilized to measure the shape/size of parts in the 3D metal printing machine.

Abstract: A stretcher for transporting injured and other persons is provided utilizing a conventional board which has been modified by forming valve stem bores and a pair of depressions therein for receiving inflatable supports. The supports are formed from flexible fluid-impermeable materials such as suitable plastics or elastomerics and include valves and valve stems for filling and releasing the supports with air. Conventional, manual pumps can be utilized by emergency personnel to inflate the support as as needed. The stretcher can be utilized with the supports deflated, partially or fully as required. When inflated, the supports provide maximum comfort and stabilization to the patient who may be kept on the stretcher for extended periods of time during transportation or treatment procedures.
