Abstract
A non-contact voltage detector module pluggable to a mobile communication device. The non-contact voltage comprises an antenna, a connector configured for connecting to a connector of a mobile communication device, and an assembly coupled to the antenna and the connector. The assembly converts an electromagnetic field received by the antenna to an indication of a strength of the electromagnetic field and transmits the indication of the strength of the electromagnetic field via the connector.

A non-contact voltage detector module pluggable to a mobile communication device, comprising:
- an antenna;
- a first connector configured for connecting to a connector of a mobile communication device;
- and
- an assembly, coupled to the antenna and the first connector, that converts an electromagnetic field received by the antenna to an indication of a strength of the electromagnetic field and transmits the indication of the strength of the electromagnetic field via the first connector, wherein the assembly further converts the electromagnetic field received by the antenna to an indication of a power mains frequency and transmits the indication of the power mains frequency via the first connector.
A non-contact voltage detector module pluggable to a mobile communication device, comprising:
- an antenna;
- an analog module coupled to the antenna that amplifies an input from the antenna, filters the amplified antenna input, and rectifies the filtered input;
- a processing module coupled to the analog module that converts the rectified input from a time varying analog value to a sequence of digital values and converts the digital values to a pulse signal restricted to a frequency range of a human voice where the frequency of the pulse signal is determined by the processing module based on an amplitude of the digital values;
- a signal conditioning module coupled to the processing module that smooths the pulse signal;
- and
- a connector coupled to the signal conditioning module that outputs the smoothed pulse signal.
A method of determining that an electrical power line is energized, comprising:
- receiving a signal by an antenna of a non-contact voltage detector module connected to a mobile phone, where the signal comprises an electromagnetic field radiated by an energized electrical power line;
- amplifying the received signal by the non-contact voltage detector module;
- rectifying the amplified signal by the non-contact voltage detector module;
- converting the amplified signal to a pulse wave signal by the non-contact voltage detector module, where a frequency of the pulse wave is determined by an amplitude of the amplified signal;
- smoothing the pulse wave signal by the non-contact voltage detector module to form an alternating current signal comprising a first harmonic frequency that corresponds to the frequency of the pulse wave;
- outputting the alternating current signal by the non-contact voltage detector module to the mobile phone;
- processing the alternating current signal by a non-contact voltage detection application executing on the mobile phone to detect an energized state of the electrical power line;
- and
- presenting an indication of the energized state of the electrical power line by the mobile communication device.
