  • Automatic activation of speed measurement in mobile device based on available motion indicia
    Patent number: 9185525
    Abstract: A system and method for speed measurement of a mobile device using a speed which does not need to be continually activated.
    Type: Grant
    Filed: January 14, 2013
    Date of Patent: November 10, 2015
    Assignee: BlackBerry Limited
    Inventors: David Blaine Dietz, Nagula Tharma Sangary, Sean Bartholomew Simmons, Mihal Lazaridis, Jonathan Cyril Skilton Doll, Perry Jarmuszewski
  • Method and system for characterizing a radio channel of a wireless network using variability of synchronization
    Patent number: 9002292
    Abstract: A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.

  • Automatic activation of speed measurement in mobile device based on available motion indicia
    Patent number: 8355751
    Abstract: A system and method for speed measurement of a mobile device, using an speed sensor such as a satellite navigation system or an accelerometer, does not need such speed sensor to be continually activated. The system and method make use of a monitor for monitoring at least one motion indicium for indicating that the speed of the mobile device is above an initial threshold, including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations visible to the mobile device; monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device. When the monitor determines that the mobile device may be travelling in excess of a threshold speed, a speed sensor is activated to confirm the indication.

  • Safety for mobile device users while driving
    Patent number: 7898428
    Abstract: A mobile device configured to have at least one function disabled when a speed of the mobile device exceeds a threshold. The mobile device includes an output component configured to provide a notification related to disabling the at least one function. The mobile device also includes a first input component configured to promote controlling whether to disable the at least one function.

  • Estimation of the speed of a mobile device
    Patent number: 7895013
    Abstract: A mobile device configured to estimate the speed at which it is moving. The mobile device includes a timing component configured to perform a plurality of Doppler shift measurements on a timing signal received by the mobile device. The mobile device also includes a processing component configured to correlate the size of the range of the plurality of Doppler shift measurements to the speed at which the mobile device is moving.
