In a 1983 article entitled An Optical Method for Investigating the Microwave Characteristics of DNA and other Biomolecules in Solution, by Mays L. Swicord and Christopher C. Davis, published in the journal Bioelectronmagnetics, experimental results were reported which determined that "A significant increase in the absorption of DNA solutions as compared with pure water has been observed that is consistent with microwave absorption by the longitudinal mode of the double helix". Thus, in their conclusion Swicord and Davis state that: However, the results presented in this work are in good agreement with the Prohofsky model of acoustic mode absorption by varying lengths of DNA. Prohofsky and Van Zandt predicted that 450 to 2000 base pair segments of synthetic DNA should absorb 10.sup.3 to 10.sup.4 times as strongly in the microwave region as an equivalent mass of water with a decrease in peak absorption due to water damping. The 1.7% dilution of DNA investigated by PFLOH spectroscopy in this work indicated a 40% increase in absorption above pure water at 8 GHz and at 10 to 12% increase at 12 GHz. The measured DC conductance of this DNA sample was quite low yet its absorption coefficient was still 25% higher at 8 GHz than a saline solution of 20 times greater DC conductance. We conclude therefore that the observed absorption of the DNA solution does not come from ionic behavior.
The observed absorption is suggestive of direct microwave absorption by the longitudinal acoustic mode of the double helix discussed by Prohofsky and co-workers. Based on the concentration of DNA solution which gave 40% more absorption than pure water at 8 GHz, the microwave absorption of DNA at this frequency is 24 times greater than an equivalent mass of water."
As used here, the term "non-ionizing radiation," is in reference to types and frequencies of radiation which do not have the capacity to force electron shifting at an atomic level, including with molecular effect.

Current electromagnetic field generating communication devices allow the transmission of electromagnetic field though the human head, and are typically held in direct contact with the head of the user. While the SAR standards currently viewed as "safe," by the FCC rely upon an assumption that the device involved is held at an inch from the head of the user, the practical experience of the typical end user is to hold the device in direct contact with the ear. The inch presumption, however, may be different for several manufactures, but generally lies within 1/2 to 11/2 inches. Microwave devices, including variants of mobile and portable telephone devices broadcast electromagnetic waves, including but not limited to the radio waves which serve as conduit for the transmission of information, by modulation of amperage or frequency or varying combinations thereof. As discussed above there is competent scientific data indicating that information carrying microwave broadcast near the human body will result in DNA damage and can result in the formation of cancers. In addition, other data indicates that cellular device users with smaller skulls may receive a microwave dosage in inverse relationship to relative skull size, and that, further, the shape of the interior of the skull, including as to concavity, may have a focusing effect, potentially resulting in "hot spots" of electromagnetic signal absorption.
U.S. Pat. No. 7,499,722 to McDowell et al entitled "Proximity Regulation system for Use with a Portable Cell Phone and a Method of Operation Thereof" discloses a portable cell phone including a sensor that determines the proximity of the sensor to a designated part of a user's body (including the head), and controls the transmit power level in response. Thus the transmit power level of the phone is controlled to various "allowable proximity transmit power levels" depending on the vicinity of the portable cell phone to different parts of the user's body.
U.S. Pat. No. 7,146,139 to Nevermann entitled "System and Method for Reducing SAR levels'" similarly discloses a mobile communications device having a sensor assembly for detecting proximity to a human body and a controller to reduce the average power level of the communication device to less than a predetermined acceptable level. Nevermann discloses that in some embodiments, the power level may be reduced only to the point necessary to maintain adequate signal strength, while in other embodiments the power level may be reduced as required regardless of signal strength in which case a communications link may be dropped.
U.S. Pat. No. 6,934,515 to Wallach entitled "Electromagnetic Radiation Alerting Device for Use With a Cellular Telephone" discloses a phone that is operable in different modes selected by the user (such as "near", "normal" and "far" that are calibrated for different distances of the user's head from the antenna), a RF sampling unit for measuring the EMF generated by the cell phone's antenna during its active transmission times and an alerting unit (audio, buzzer, visual) that alerts the user when a predetermined radiation level is exceeded for the selected mode of operation.
U.S. Pat. No. 6,456,856 entitled "Mobile Radio Equipment forming Antenna Pattern to Protect User From Radiation". This reference discloses a proximity detection device for measuring humidity or temperature and to detect the presence of human tissue in the vicinity of the device and to adjust transmit power in a directional antenna as a function of the data produced by the detector.
FIG. 1 shows an embodiment of a mobile device utilizing a non-audible sound wave (Sonar, Sonic) to determine the distance and thus issue a warning to the user. As shown the mobile device 1 includes a sonic signal broadcast source (transmitter) 120, and a sonic signal recipient microphone device (receiver) 110 and an acoustic warning device (speaker) 130. The warning device while shown as acoustic in FIG. 1, may also be visual, thermal, tactile or electrical and its depiction throughout the disclosure as one type is not intended to be exclusive. The warning signal may be emitted in increasing volume (intensity) and/or variation in sound frequency (tone), so as to cause a progressive proximity warning to the end-user and at higher transmit power levels actually interfere with the effective use of the device for communication. As a result of increase in intensity of the sonic signal return 105, the forced switching of the device, with respect to its broadcast ability, to the "off" condition, may be desirable. In addition a time circuit 140 on FIG. 2 can be used so as to allow short term override of the warning or interruption, or to set time-based standards for warning signal initiation. All implementations of switches, including micro-switches, which may be employed to cause open or closed circuits for initiation of an information transmission signal (Warning Signal) in a mobile device, when the default condition, or as such switches may be used to vary the intensity of sonic warning signal issued.
Embodiments described herein may additionally be actuated by the angle of the mobile device or angle of incident. By this is meant an angular position measurement switch such as of the sort used in currently marketed battery operated equipment which have automatic angular recognition, such as with the auto on/off function of the certain Bushnell equipment such as the 1.times.28 Red Dot Sight with auto on/off. Thus, when flat on a table, or within such other angular positions as the manufacturer may elect, the Method and Device may default to the off condition.
In addition the embodiments described herein may be implemented, via either electrical circuit or via software, so that the disclosed subject matter deployed will not interrupt broadcast and receipt of messages or voice whenever either the "speakerphone" or similarly named "speaker," aspect of the mobile device is engaged, or a headset is in use and thus the risk of exposure is greatly depreciated.
FIG. 3 shows the depth of field and pattern recognition based proximity warning system enabled in a mobile device 1. The embodiment as illustrated in FIG. 3 includes a horizon sensing device 305, which may include but not limited to the use of accelerometer circuitry for determining an angular range within the vertical axis of the mobile telephonic or similar device, so as to encompass all angles consistent with direct handset to ear orientation for speech, which activates, or increases frequency of proximity detection and exposure determining processes. The mobile device includes intermittent broadcast "active" auto focus (typically infrared) module for broadcast, receipt, and processing of light data (so thereby to define a distance), and determining when a distance within predetermined parameters is reached. The embodiment also includes CMOS 395 or similar module light recipient device, which captures images at the depth of field range assigned by the auto-focus module, the image may then be processed by the image processor 390 and the pattern recognition programmed chip 380, where a search is conducted in a processor 370 for images consistent with aspects/characteristic of the human head, such as an "ear," (and which may, as a condition of sale, include an initial photograph of the ear of the end user) or other characteristics, so that when there is a coincidence of factors including a set distance from "ear," or other feature within programmed parameter (such as 1.25 inches) the warning signal is emitted from an indicator 350, which if audio is in increasing volume and/or variation in sound frequency, so as to cause a proximity warning to the end-user and if the transmission levels are sufficiently high cause interfere with the use of the device for sound transmission. The result of an increase in intensity of the sonic signal return, forces the switch 360 of the device, as to broadcast, to the "off" condition. In addition a timer circuit 340 can be used so as to allow short term or temporary override of the switch, or to set time-based standards for warning signal initiation. Each of the elements described in FIG. 3 may be implemented in processes and hardware resident on the mobile device 1 with only additional programming required.
The angular detection and thus management of the embodiments described herein may be by the use of accelerometers, electronic level circuitry (such as found variously, but in example in the Bushnell X 28 Trophy rifle scope, with its "auto on/off system) such that the intermittent broadcast of distance measuring light or other measurement electromagnetic signal may initiated only when a cellular handset or similar device falls within planes of the vertical corresponding to cellular telephone use for broadcast.
While illustrations herein may include reference to a separate speaker system for the warning process, and while such separate speaker system may be a desired approach to implement the disclosed subject matter, the embodiments disclosed may alternatively make use of the "standard" speaker (ear piece) with which mobile devices are otherwise normally equipped, sans the Method and Device as hereby described. In plain language, the standard speaker can be optionally used for the broadcast of the intermittent calibrated acoustic signal, thereby eliminating the need for a separate speaker for that purpose.
FIG. 4 is a flow chart of an embodiment in which the angle of incident is used to determine use of the mobile device and thus radiation exposure. As shown in Block 401 angles of incident are established that corresponding with its use by the user for communication. These angles of incident or ranges of angles may be determined by a control period in which the angles of incident are compiled and associated with the mobile device status, such as associated with active communication session or with no communication sessions, this association may be determined manually or autonomous. The angles of incident may then be statistically processed to determine the likely range of angles that would indicate the mobile device is in use by the user. For example if over a control period 70 percent of the time when the phone is within 10 degrees of perpendicular from the horizon it is in use and over the same control period only 2 percent of the time when the phone is greater than 10 degrees from horizontal it is in use, a statistical analysis may establish the target angle of incidences being between + or -10 from horizontal. Similarly, if over the control period the mobile device is never engaged in a communication session when within 10 degrees of horizontal the established angles of incident may be 10 to 170 degrees.
