  • Patent number: 11919357
    Abstract: A suspension system for a wheel assembly of a vehicle includes a telescopic damper configured to mediate between respective sprung and unsprung portions of the wheel assembly, a rebound spring arranged to moderate wheel travel, and a force-transfer system operative to apply a force to change one or more parameters of the suspension system. The application of the force by the force-transfer system is effective in a first operating mode to change a length of the telescopic damper and in a second operating mode to regulate a wheel rate of the wheel assembly. The force-transfer system is controllable to modify a wheel-travel value at which the wheel rate of the wheel assembly changes in the second mode of suspension operation.

  • Publication number: 20180014158
    Abstract: A system, method, and computer program product provides recommendations with a mobile device recommendation system to a user of a mobile device. The recommendation system collects data set A comprising ambient sensor data from sensors of a plurality of mobile devices of a selected population located remote from the mobile device of the user. A data set B is also collected over the network wherein data set B comprises social media data transmitted from and/or related to a plurality of venues and/or events located within a selected geographic area. A data set C comprising data received from the user of the mobile device and/or the mobile device of the user is also collected. The data sets A, B, and C are analyzed and a recommendation is provided of at least one of the venues and/or events within the selected geographic area based upon the analyzed data.
