System and method of on-body mobile devices to reduce radiation exposure to the upper body

摘要

A system of mobile devices that reduces the transmission strength of outgoing signals originating from a handheld device, and sends such signals to a second device, situated near or on a lower-body location, where the signals may be amplified to the current permitted maximum transmission strength vis-a-vis the brain (SAR), or above that level to the greater maximum strength permitted in the areas of, e.g., the feet and ankles, where the signal is then sent outward. The devices divert radio frequency (RF) radiation exposure downward toward the lower extremities. The intelligence and power of the devices may be split between two or more devices, resulting in longer use time, deeper and more complex computing capability, and fewer disruptions due to power. In addition, a benefit in one or more embodiments is better, more reliable reception, due to the use of two or more coordinated receiving antennas.

主权项

1. A mobile system for pushing downward radio frequency (RF) communication signals generated by at least one mobile electronic device toward a lower portion of a body of a user of the at least one mobile electronic device in order to lower RF radiation exposure at a head or an upper portion of the body of the user, comprising:
at least one first transceiver in the at least one mobile electronic device and arranged to be placed on or adjacent to the head or the upper portion of the body of the user; and at least one second transceiver that communicates with the at least one first transceiver, the at least one second transceiver being on the body of the user at a position lower than the at least one first transceiver, wherein the at least one first transceiver is configured to establish RF communication with the at least one second transceiver using low-power, short-range RF communication signals, wherein the at least one second transceiver is configured to boost a signal strength of the short-range RF communication signals to high-power, long-range communication signals and then to retransmit the long-range RF communication signals to a remote recipient, so that the RF radiation exposure at the head or the upper portion of the body of the user is reduced; and wherein the at least one second transceiver switches into emergency text-only mode when the at least one first transceiver has almost run out of power.
