Modular dual-mobility articulations in patients with adverse spinopelvic mobility
The Bone & Joint Journal, 2022Aims Adverse spinal motion or balance (spine mobility) and adverse pelvic mobility, in combination, are often referred to as adverse spinopelvic mobility (SPM). A stiff lumbar spine, large posterior standing pelvic tilt, and severe sagittal spinal deformity have been identified as risk factors for increased hip instability.

Dual Stewart platform mobility simulator
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005A robotic mobility simulator is being developed to allow training on various hapticly simulated surfaces while still being in the safe clinical environment. The simulator is integrated with a rich virtual environment displayed in front of the patient. The system uses two Stewart platform robots to render the walking surface geometry and condition.

Dual Mobility in Total Hip Arthroplasty
Orthopedic Clinics of North America, 2014Dual-mobility articulations have shown promising results. Postoperative instability remains the most common reason for revision of a total hip arthroplasty (THA). Dual-mobility cups have been shown to decrease the rate of dislocation in primary THA and have been used to treat and prevent instability in revision THA.

Mobility enhancement design and control for a Dual-Wheel Dual-Armed Mobile Manipulator
2015 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2015Recently domestic Wheeled Mobile Robot(WMR) such as "iRobot Roomba Vacuum Cleaning Robot" is becoming popular. However, such WMR has poor mobility to surmount the obstacles like the door sill, which greatly limits its functionality. Instead of using complex wheel mechanisms, another possible solution is to use external manipulator.

Dual mobility cups have two points of articulation, one between the shell and the polyethylene (external bearing) and one between the polyethylene and the femoral head (internal bearing). Movement occurs at the inner bearing; the outer bearing only moves at extremes of movement.Dislocation after total hip arthroplasty (THA) is a cause of much morbidity

A mobile data system that uses two significantly different data rates on the air interface is described. In a cellular system it is the conditions prevailing for a mobile terminal at the cell border that is setting the limit for a reasonable data rate. However, there are conditions in the cell, e.g.

Dual mobility cups are a new valuable option in treating and preventing dislocation in primary and revision THAs. In contrast with all alternative treatments such as f.e constrained liners, they do not compromise the implant durability and the clinical outcomes [1].

Dual-Polarized RIS-Assisted Mobile Communications
IEEE Transactions on Wireless Communications, 2022Reconfigurable intelligent surface (RIS) has drawn worldwide attention because of its attractive capability to improve the electromagnetic propagation environment and surprising advantages of low cost and low power consumption. Recently, RIS is further advanced to realize the independent control of two orthogonal polarizations in real time.

Dual wideband radiating element for mobile handsets
Microwave and Optical Technology Letters, 2003AbstractA lightweight, low‐cost antenna suitable for personal communication handsets is proposed. This antenna consists of two stacked quarter‐wavelength elements short‐circuited along the same plane. A slot was embedding in each patch to allow the achievement of two widebands, including GSM and DCS/PCS/UMTS system applications.
