Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Finite Element Analysis of Double Arc and Quadruple Arc Spiral Bevel Gear based on Abaqus
The quadruple arc spiral bevel gear is a new type of gear with quadruple arc tooth profile applied to the spiral bevel gear. The three-dimensional model is built in Solid Works based on the tooth surface equation of spiral bevel gear with circular arc ...

Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics
Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears
ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.

Precision Measurement of Spiral Bevel Gear based on Laser Displacement Sensor
Based on the analysis of the characteristics of the existing bevel gear measurement technology, a non-contact measurement method of the bevel gear is proposed based on the laser displacement sensor and the algorithm of the tooth distance deviation, the ...
