Abstract: Systems and techniques to ensure reliable operation of devices, such as medical devices, that are configured to execute installed software are described. A secure software update process for the device utilizes multiple integrity checks in order to prove that software integrity has not been compromised before the device is allowed to be put into service with the software installed thereon. Also described is a computer architecture for an external defibrillator that isolates the execution of installed software applications by separately compiling the code for those applications and by executing the separately-compiled applications on different processors of the defibrillator. Among other things, this allows the defibrillator to be “brought online” faster, such as to deliver a shock to a patient.

Abstract: An outrigger grinding fixture to support a workpiece on a manual surface grinder having a worktable and a grinding wheel. The outrigger grinding fixture comprises a base member maintained on the worktable. A slide member has a V-shaped slot formed on an upper edge. A mechanism is for horizontally adjusting the slide member on the base member. Another mechanism is for preventing vibration of the workpiece when the grinding wheel engages with the workpiece.
