Abstract: The devices and systems disclosed herein improve on existing weapon system control handles, by replacing complicated spring and cam components with a gauge shaft. The use of a gauge shaft eliminates unnecessary part-complexity and extra assembly labor. The use of a gauge shaft increases operational response and accuracy while decreasing cost and weight of weapon system control handles. Moreover, the gauge shafts can be readily repaired or replaced, reducing the overall costs of maintenance associated with damaged weapon system control handles. In alternative embodiments, a disk gauge is used in place of gauge shafts.

Abstract: An insufflator (1) during initial insufflating of a cavity (3) determines a set pressure value and a value of a residual volume of insufflating gas which should be drawn from the cavity (3) during evacuating of insufflating gas from the cavity (3) at the end of a laparoscopic or other procedure, so that on completion of evacuating of the cavity, substantially no insufflating gas remains in the cavity. The set pressure value is determined from a pressure/volume relationship between the pressure in the cavity (3) and the cumulative volume of insufflating gas delivered to the cavity (3) represented by the first graph line (37). The insufflator (1) determines the set pressure value as a pressure value slightly greater than the transition pressure represented by the point of inflection (45), at which a first pressure/volume relationship represented by the first part (40) of first line (37) transitions to a second pressure/volume relationship represented by the second part (41) of first line (37).

Abstract: Disclosed herein are systems and methods that allow activation of and intuitive interactions with a companion-display mode for an electronic device. In one aspect, a first device receives a request to annotate content on the first device. In accordance with a determination that a second device is available for displaying the content in an annotation mode and has not been previously approved to display the content in the annotation mode, the first device displays a selectable option that, when selected, causes the first device to send an instruction to display the content in the annotation mode at the second device. When the electronic device is available for displaying the content in the annotation mode and has previously been approved to display the content in the annotation mode, the first device sends an instruction to the second device to display the content in the annotation mode automatically without further user intervention.
