Abstract: A method is described for coalescing input/output (IO) interrupts to a virtual machine (VM) running on a host computer. At a virtualization layer of the host computer that supports execution of the VM receives an IO interrupt in response to a completion of an IO request of the VM, wherein a transmission of the IO request by the VM to an IO device bypasses the virtualization layer. The virtualization layer then determines whether the VM has responded to a most recently delivered IO interrupt to the VM by the virtualization layer, and drops the IO interrupt if the VM has not responded to the most recently delivered IO interrupt, thereby failing to deliver the IO interrupt to the VM.

Abstract: An intraperitoneal cleaner to allow cleaning of a scope lens used in minimally invasive surgery is presented. Using existing super elastic alloys in combination with a standard spring, a purely mechanical cleaning action is provided, eliminating the reservoirs, vacuum pumps, or extra ports found in other cleaner designs. The scope body is inserted into the device prior to commencement of surgery, and the wiper of the cleaner rests just outside of the field of view of the lens of the scope. When debris or fluid obscures the field of view, a spring in the handle is compressed, allowing the cleaner to flex and provide a cleaning action. A cordless laparoscopic light source using LEDs and a pair of aspherical condensing lenses to focus the resulting light to a usable point is presented. By using battery power, the entire device is considerably smaller than the current xenon light source standard.
