摘要:
Disclosed is an extruded, open-cell microcellular alkenyl aromatic polymer foam useful in insulating applications. The foam has an open cell content of about 70 percent or more. The foam has an average cell size of about 70 micrometers or less. The foam is particularly useful in evacuated or vacuum insulation panels. Further disclosed is a process for making the open-cell foam. Further disclosed is a fabricated foam article.

摘要:
An interactive medical training device includes a computer system having a display, wherein the computer system is programmed to provide education and training in medical procedures, including laparoscopic surgical procedures. This aspect is achieved by configuring the system to display, on a portion of the display, a video window. The video window displays a prerecorded video segment illustrating a portion of a laparoscopic surgical procedure. The system requests a user to input information relating to a next step in the surgical procedure, which advantageously keeps the user engaged in the training session. This "next step" information may include, for example, selecting an appropriate medical instrument or selecting a location for operating. The user inputs the requested information through an input device, such as a mouse, a keyboard, a touch-sensitive screen, or other input device. The system then receives and interprets the user input and informs the user as to whether the input is correct. Preferable, if the input is correct the system will display a prerecorded video segment illustrating the next step of the surgical procedure.
