  • Publication number: 20130048782
    Abstract: An apparatus for measuring an air pressure includes a linear retaining means, a towed device, at least one pressure sensor for acquiring a static pressure, and an actuating device that can be positioned in an aircraft, for retracting and extending the linear retaining means. The towed device includes an enclosure, an autarchic voltage supply and a wireless first communication device that is connected to the autarchic voltage supply. The first communication device is equipped to transmit signals and/or data that represent acquired measurement data to a second communication device. Consequently, the linear retaining means can be attuned purely to the task of retaining the towed device and does not need to carry out any secondary tasks of transmitting signals and/or measured data.

  • Publication number: 20120172849
    Abstract: A system detects whether a pneumatic surgical instrument is attached to a surgical system. A drive valve has an input for connection to a source of pressurized air, an output for connection to the surgical instrument, and an exhaust for exhausting pressurized air during operation of the surgical instrument. A pressure transducer in communication with the exhaust senses a pressure profile of air flow from the exhaust. A first sensed pressure profile indicates that the surgical instrument is connected to the output and a second sensed pressure profile indicates that the surgical instrument is not connected to the output. A detection circuit connected to an output of the pressure transducer detects whether the surgical instrument is attached to the surgical system based on the sensed pressure profile.
