  • Publication number: 20180109940
    Abstract: Methods for obtain identifiers, such as International Mobile Subscriber Identities (IMSIs) and International Mobile Station Equipment Identities (IMEIs), of mobile communication terminals, and associate these identifiers with other items of identifying information provided by users of the terminals. A local interrogation device may be installed that imitates a legitimate base station belonging to a cellular network, at a control checkpoint. Local interrogation devices are connected to a global interrogation device in a hierarchical network, whereby the local interrogation devices are assigned a priority that is higher than that of the global interrogation device. The global interrogation device provides cellular coverage to a larger area that contains the control checkpoints, while the local interrogation devices provide more localized cellular coverage to the control checkpoints.

  • Patent number: 8723443
    Abstract: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.
