  • Modeling lung motion using consistent image registration in 4D computed tomography for radiation therapy
    Two respiratory measurements – tidal volume from quantitative spirometry and a digital voltage signal from a wraparound differential pressure sensor (“pneumo bellows ”) – are simultaneously acquired (Fig. 1). … be a useful, verifiable physiologic measurement.6 The bellows system consists of an accordion -like cylindrical bellows …
  • Dosimetric variances anticipated from breathing- induced tumor motion during tomotherapy treatment delivery
    To obtain the breathing data for the 52 patients used in our study, two respiratory measurements—tidal volume from quantitative spirometry and a digital voltage signal from a wrap-around differential pressure sensor (‘ bellows ’), were simultaneously acquired as described by Lu … The bellows system consisted of an accordion -like cylindrical bellows strapped around the patient’s abdomen.
  • Basics of Pressure Regulation
    As illustrated from the bellows used in the 15 Series regulator (Figure 22), the sensor is larger than the first two sensing elements. Bellows have accordion style pleats or flexing points (Figure 23) which provide the capability for longer valve … This is the facilities regulator designed to provide high flow capacity at relatively low pressures .
  • ISA IND PRESS LVL DENS MEASRMNT - Industrial Pressure, Level, and Density Measurement
    … form deep convolutions, which enable the element to expand in much the same manner as an accordion . The bellows are sealed on the free end; pressure is applied to an opening on the stationary end. Pressure sensors that depend on the deflection of an element have been used for many years.

    The outlined yellow region highlights where the bellows ' accordion collapses onto itself, shown in the 50%, 75%, and 100% images. Based on their negative pressure functionality in the medical field, bladder pumps were considered to be a … It is monitored by connecting the end of the tube directly to the Vernier Gas Pressure Sensor .
  • International Astronautical Congress (IAF) > Mitigating Extreme Environments for In-Situ Jupiter and Venus Missions
    The bellows would be flexible enough that it could be compressed like an accordion for storage on the way to Venus, and sturdy enough that it could survive the acidic clouds. Consequently, high temperature motors and actuators, gear boxes, position sensors , ca- bling, and mechanical devices related to … In addi- tion to high temperature and pressure , chemical corrosion can significantly limit the useful life and …
  • Embedding without disruption: The basic challenge of sensor integration
    Second, we can get stretchability from the geometry such as the zigzag bellows af an accordion or an old camera. … made by high temperature processes like casted aluminum may be a host for direct sensor embedding [8]. … device is placed via a mounting into the casting mould and a high pressure die casting process …
  • Soft Robots Make World Safer for Humans | iRobot Advanced Inflatable Robots
    … they might need to let out air to soften or pump up the pressure to become rigid. The robot spider's legs use elastic bellows drives as joints. … in the mechanism itself — complexity adds to costs in the motors and sensors — or places … … bending an inflated arm has required cables connected to motors or pneumatic bellows that act like accordions .

    Figure 6-5: End caps and mounting configuration of temperature sensors . In a rigid container the melting would lead to a large pressure increase which would cause the … … in contact with the hot absorber plate as it shrinks, a spring loaded rubber bellows is used. It was folded in an accordion pattern giving a total relative density of s = 0.087.
