Abstract: A personal protective positive pressure device includes a mask with an inlet connector and a tube with a first connector and a second connector. The tube is connected through the first connector to the inlet connector of the mask and the tube is connected through the second connector to an air nozzle of a ventilation system onboard a transportation vehicle. The personal protective positive pressure device is configured to limit inhalation of airborne pathogens while traveling on the transportation vehicle and to inspire confidence in the safe use of public transportation.

Abstract: Spring set configurations that include an advantageous combination of spring geometries are disclosed. Spring elements having curved and straight sections, orientation of spring element anchor points with respect to the common radius, orientation of spring element segments with respect to a specific axis, balance of the length of spring elements about the common radius, and mass balance about the common radius can be used to mitigate unwanted out of plane motion. The spring set provides planar motion while reducing undesired out of plane motion making MEMS devices substantially insensitive to the process-induced etch angle variations of the spring elements. The spring set can be used in a MEMS gyro device which maintains the desired resonant modes and consistently low quadrature error even with process variations in manufacturing causing undesirable etch angles.
