A system, comprising: a first low power wireless transceiver; a second low power wireless transceiver configured to transmit a first positioning request to the first low power wireless transceiver over a low power wireless link; a cellular radio transceiver configured, in response to the first low power wireless transceiver receiving the first positioning request, to transmit a second positioning request to a base station of a cellular network, and configured to receive, as a reply to the second positioning request, first positioning data from the base station of the cellular network; wherein the first low power wireless transceiver is configured to transmit second positioning data, determined by the first positioning data, to the second low power wireless transceiver over the low power wireless link as a reply to the first positioning request.

Apparatus, system and method for determining position by use of a low power wireless link

A frequency divider including at least one frequency divider cell having an adjustable circuit configuration which may be selected adaptively according to properties of an oscillator signal to be frequency-divided in the frequency divider. Accordingly, the circuit configuration of the frequency divider may be changed on the fly during the operation.

Circuit configuration of a frequency divider

A lightning detector for lightning detection and a lightning detection method, wherein the lightning detector uses at least two separate channels or frequency bands for lightning detection, and wherein the lightning detector is a mobile RF device provided with radio interfaces for at least two communication channels or frequency bands, whereby at least one of which is normally a telecom channel/frequency range and wherein these channels/ranges are used in lightning detection.

Detection of lightning

A lightning detector for lightning detection and a lightning detection method, wherein the mobile lightning detector is provided with an antenna, an amplifier front-end, an A/D converter and a digital signal processor, and wherein the lightning detector is a mobile RF device provided with an audio codec whereby the preamplifier of the codec is used for amplification of the detected lightning signal, the A/D converter of the codec is used for the A/D conversion of the amplified lightning signal, and whereby the digital audio processing unit of the codec is used for the signal processing of the lightning detection.
