Personal communications device with cross router

A portable communications device (PCD) for communications over a plurality of communication channels and a cross router for controlling one or more of the communication channels to be active. Typically, the plurality of communications channels includes a cellular channel, a satellite channel and a WiFi channel.

Dual-radiation non-ferrous metal prospecting system

Methods and apparatus for a Dual Emission Non-Ferrous Metal Prospecting System are disclosed. One embodiment comprises methods and apparatus for finding metal deposits in the Earth, and then determining whether these metal deposits are ferrous or non-ferrous. One embodiment includes an Electromagnetic Quartz Penetrator. The Electromagnetic Quartz Penetrator includes a transmitter, a receiver, antennas and a first signal processor. One embodiment also includes an Omni-Directional H Field Metal Exciter and Sensor. The Omni-Directional H field exciter produces an output which has a spatial dissipation rate proportional to a factor of 1/r, and, therefore, has a relatively short range compared to the Electromagnetic Plane. 1. An apparatus comprising:an electromagnetic quartz penetrator; said electromagnetic quartz penetrator including a transmitter and a receiver;said receiver including a signal processor;said electromagnetic quartz penetrator being aimed at a two-dimensional surface of the Earth;said electromagnetic quartz penetrator transmitter generating an Electromagnetic Plane Wave having mutually orthogonal electric and magnetic field components;{'sup': '2', 'said planar wave being aimed generally orthogonally to said two-dimensional surface of the Earth, and having a spatial dissipation rate proportional to a factor of 1/r;'}said planar wave being used to identify a relatively small three-dimensional volume of Earth adjacent to said two-dimensional surface;said three-dimensional volume of Earth being identified as containing a deposit of metal by said electromagnetic quartz penetrator;said planar wave causing a reflection from said deposit of metal which is captured by said receiver;said receiver including said signal processor for interpreting said reflection from said deposit of metal;said receiver including a display for indicating the approximate spatial coordinates of said deposit of metal from said two-dimensional surface of the Earth;an H field metal ...
