Title: Detection and documentation of tailgating and speeding violations
Inventor: YANIV ALON
IPC: G08G1/054
Filed: 2015-05-18
Abstract: A camera 4 mountable on a host (e.g. law enforcement patrol) vehicle 20 captures a timed sequence of image frames of a vehicle 16 at known capture times. Images of part of the vehicle are selected from the image frames to provide respective image coordinates of the vehicle. The vehicles model is recognised from the image frames (e.g. by recognising its license plate and an associated model) and a vehicle dimension is known therefrom. World space coordinates (X,Z) are computed (Fig.3) from the image coordinates and known dimension. Vehicle speed is calculated from the capture times and world space coordinates and it is determined whether it is in violation of a speeding regulation. The cameras optical axis may be perpendicular (Fig.4) or parallel (Fig.7A) to the direction of motion of the vehicle. The host vehicle may be travelling parallel to the vehicle, their relative speed may be determined and the host vehicle speed may be input from its CAN bus.

Title: Controlling connectivity of an electronic device to a mobile network
Inventor: PAUL MARSHALL
IPC: H04W12/00
Filed: 2020-03-10
Abstract: If it is determined that a subscriber identity module (SIM) in an electronic device does not have permission to communicate using a mobile network, the contents of the SIM are modified. This modification prevents the SIM from responding to a request for data for initiating a communication request, the request coming from the modem or processing unit of the electronic device. A remote system, such as a home location register (HLR), may determine whether the SIM has permission when receiving a connection request from the device. It may then modify the SIM using an over-the-air (OTA) message, sent after a threshold number of failed connection attempts. The SIM may also monitor connection attempts itself and perform the modification if the number of failed attempts exceeds a threshold value. Modification of the SIM may involve destroying or writing data on the SIM, or changing an access permission. The system prevents an electronic device from repeatedly attempting to connect to a mobile network which it is not permitted to use.
