A security device provisioning hub, including: a memory; and a processor configured to: receive a first secret token from a device manufacturer, wherein the first secret token is associated with a first service; receive a second secret token from a customer device having a security chip; verify that the first secret token and the second secret token are the same; and provide to the customer device access credentials to the first service.

Certificate provisioning and customer binding mechanisms using device group identification token

A wireless receiver is activated periodically to measure the level of received signals. It measures the average received level over a plurality of the activation periods, and enables the supply of power to receiver circuitry dependent on the measured average value. In one embodiment the power is enabled if an increase in the average value is detected which is greater than a predetermined margin. The average value may be measured in a sliding or stepped window. In another embodiment the power is enabled if the level in an activation period exceeds the average value by a predetermined margin.

Power supply control in a wireless receiver

A communications network comprising a plurality of nodes, each comprising a network device and a network interface, at least one of the nodes having a first local power manager associated therewith and adapted to control power to the network device.

Communications network with nodes having power control capability

The invention relates to a filter device () for detecting and/or removing erroneous components like noise, deformations, glitch components or other errors in and/or from a signal, to a demodulation device using the filter device, to an information transmission system using the demodulation device and to a method for detecting a noise impulse in an input signal (C&#x3b1;(t), C&#x3b1;[k]). The filter device includes a summing element (-N,) connected to a correction element (). The summing element (-N,) sums the input signal (C&#x3b1;(t), C&#x3b1;[k]) within a reference interval (N) and the correction element () verifies the summed input signal (IS[k]) with at least one signal condition (, N+1, &#x394;C&#x3b1;[k]). Finally, the correction element () outputs a predetermined signal (C&#x3b1;[k]) based on the result of the verification between the summed input signal (IS[k]) with at least one signal condition (, N+1, &#x394;C&#x3b1;[k]). The foregoing filter device is able to remove noise from an input signal. This stabilizes the input signal against environmental influences occurring e.g. during signal transmission.

Filter device for detecting and/or removing erroneous components in and/or from a signal

A signal transmission system (STS) comprises a transmitter (T) with a first LC circuit comprising a first coil (C) intended to be fed with signals having a chosen carrier frequency, and a receiver (R) with a second LC circuit comprising a second coil (C) and coupled to a circuit front-end (FE). The first coil (C) is arranged to transfer energy to the second coil (C) by magnetic induction in a near-field propagation mode. The first LC circuit (C) has an increased quality factor and is tuned to a first frequency which is shifted in a first direction from the carrier frequency by a first value, and the second LC circuit (C) has an increased quality factor and is tuned to a second frequency which is shifted in a second direction, opposite to the first one, from the carrier frequency by a second value.

System for signal transmission by magnetic induction in a near-field propagation mode, with antenna tuning for link budget optimization

A method of tuning an antenna is provided, wherein the method comprises receiving a first signal strength indicator indicating a signal strength of a first data signal transmitted by an antenna on a first frequency, receiving a second signal strength indicator indicating a signal strength of a second data signal transmitted by the antenna on a second frequency different to the first frequency, determining a tuning control signal based on the first signal strength indicator and the second signal strength indicator, and tuning the antenna based on the control signal.
