Patent GB-2604448-A (GB)
Title: Electromagnetic field detector
Inventor: FRASER BURTON
IPC: G01R29/08
Filed: 2021-03-01
Abstract: A method of detecting an RF electromagnetic field and demodulating information from it comprises: transmitting a probe laser signal 23 in first and second probe signal paths to an optical receiver 29, the first path passing through a transmission medium 27 in which the probe frequency excites electrons from a ground state to an excited state; and transmitting a coupling signal 25 in a coupling signal path, overlapping the first probe signal path in the transmission medium, the coupling frequency exciting electrons of the transmission medium to induce an Electromagnetic Induced Transparency (EIT) effect. An incident electromagnetic field 10 causes a change in refractive index and thus a change in an optical path length difference between the first and second probe signal paths. The first and second paths of the probe signal are combined and the intensity of light at the receiver is monitored to detect the electromagnetic field as a change in intensity caused by the change in the optical path length difference.

Title: Control system for a vehicle and method
Inventor: Waqar Ud Din
IPC: B60W30/14
Filed: 2022-05-10
Abstract: Aspects of the present invention relate to a speed control system for a vehicle (10) which is configured to cause the vehicle to operate in accordance with a target speed value. The speed control system comprises one or more controllers (15). The speed control system is configured to receive a pitch rate signal indicative of a rate of change of pitch of a vehicle and a driving surface gradient signal indicative of a gradient of a driving surface upon which the vehicle is being driven. The speed control system determines if the vehicle is cresting in dependence on the rate of change of pitch exceeding a predetermined value; and the gradient value of the driving surface being below a predetermined value. The speed control system outputs a speed reduction signal to reduce the speed of the vehicle when the vehicle is cresting.
