Abstract:
Systems and methods for the collection, verification, and maintenance of point of interest information are provided. One example system includes a plurality of mobile collection devices respectively operated by a plurality of human collectors. Each of the mobile collection devices uploads to one or more intermediate servers information describing one or more attributes of a plurality of points of interest. The system includes a mobile verification device that receives, from the one or more intermediate servers, information uploaded by a first mobile collection device and provides an indication of an accuracy associated with the information received from the first mobile collection device. The system includes the one or more intermediate servers. The system includes one or more production servers. The information uploaded by the first mobile collection device is transcribed from the one or more intermediate servers to the one or more production servers.
Abstract:
In one aspect, a tunable vibration damper may include a housing and a damper stack disposed within the housing. The damper stack may be formed from a viscoelastic material and may have a vertical stiffness and a horizontal stiffness. The damper stack may also include a plurality of column sections and a plurality of disk sections, with each pair of adjacent column sections being separated by one of the disk sections. The disk sections may extend radially outwardly relative to the column sections. In addition, at least one of the vertical stiffness or the horizontal stiffness may be tunable by adjusting a stiffness-related parameter of the damper stack.
