Justia Patents With Electrical ShieldUS Patent for Close-proximity radiation detection device for determining radiation shielding device effectiveness and a method therefor Patent (Patent # 6,492,957)
A radiation detection device for locally detecting radiation of RF energy emissions from close proximity direct line-of-sight electromagnetic fields emitted by a wireless transmit/receive electronic equipment antenna 22 or body 21 such as a cellular telephone, in miniature/planar design form with suitable embedding form-factoring fashioned arrangement capability joined with radiation shielding devices. Said radiation detection device operates without prerequisite need for a battery or external power source, operationally self-powered by the embodiments of this invention when exposed to electromagnetic field radiation of predetermined thresholding energy level setting for the user&apos;s own personal alerting verification and assessment means of suitable predetermined radiation detection measurement tester coupling to radiation shielding devices to encompass an overall shield effectiveness system solution in real-time monitoring response fashion operation.
As the proliferation of radiation shielding arrangement devices for wireless transmit/receive electronic equipment products make their way onto the marketplace. The assessing consideration of EMF verification and perceptible presence in measurable degree to which radiation shielding or blocking performances are determined by measured and evaluated purposes for user&apos;s of wireless electronic equipment to quantifiably determine potential presence of EMF radiating exposure levels is lacking. This measure of EMF radiation with respect to radiation shielding arrangement device shielding performances is a necessary parameter specification as part of the overall shield effectiveness system solution for the user&apos;s own personal assessment of radiation shielding arrangement device operational capability, reliability and the relative radiation safety figure-of-merit value that is provided in a real-time response evaluating fashion. Whereby said relative radiation safety figure-of-merit value is comprised of the method of shielding effectiveness figure-of-merit measure.
In accordance with the teaching of the present invention, a radiation detection device that is simple and economic to manufacture for use in conjunction with a radiation shielding devices, without altering said radiation shielding device, is disclosed. Furthermore, this invention will provide means for determining the EMF radiating exposure level at close-proximity to the radiation shielding device located near the user&apos;s predetermined sensitive human body area for means of alerting and monitoring detection and coverage protection from EMF radiating source. The invention is comprised of a transducer arrangement means, in converting the free-space transmission of EMF energy originating from a EMF radiating source with EMF energy exposing and presently accepted by the invention signal receptor and transducing said EMF energy into a visible or audible or mechanical stimulation or electrical processing output as means for said EMF energy detection verification. The degree of exposed EMF energy at the user&apos;s predetermined measuring location is presently detected by the radiation detection device in a close-proximity to EMF radiating source is proportional to the transduced EMF energy outputted by an indicator arrangement as is comprised within the radiation detection device and thereby said transduced EMF energy outputted by said radiation detection device provides the user with a measuring means for evaluating the EMF radiating exposure level at the user&apos;s predetermined criterions.
The invention operates suitably over a wide range of frequencies of the electromagnetic spectrum. The predetermined frequency operational band selection is accomplished by tuning or fixing the antenna&apos;s specification and an appropriate crystal detector tuning impedance comprising its junction capacitance of less than or about two picofarads. The coupling to the invention with a radiation shielding device, enhances overall shield system solution for a user&apos;s need for determining the effectiveness of a radiation shielding device and its reliability in a continuously monitored real time mode.
There are two test modes for detecting radiation as relating to this invention in performing the method of shielding effectiveness figure-of-merit measure, is also referred to as the radiation detection verification methodology. The first test mode is performed with a predetermined electromagnetic field radiating source such as a cell phone with the cell phone antenna placed near a user&apos;s predetermined target of measuring interest location point as located on the perspective non-blocking side of the radiation shielding device as is adjacently located next to the radiation detection device with antenna arrangement exposed sideway, or in a alternatively described perspective as referenced from an obverse perspective view is referred to as the radiation shielding side surface, then said radiation detection device with an antenna exposed side is illuminated or activated with EMF energy from said EMF radiating source. Said radiation detection device subsequently activates the stimulus indicator at a predetermined energy threshold level setting and provides means of a measurable stimulus indicator behavior response such as a light output, either flashing or in steady-state. Said output method is not limited to light. Other output such as sound or a mechanical vibration function operation or electrical processing operation, as to indicate that EMF energy or power density has been sensed by the radiation detection device on the perspective non-blocking side of the radiation shielding device, is disclosed. Additionally, this procedural process provide a first relative reference calibration measuring means for the user to indicate normal and proper radiation detection operation, thereby also providing an EMF energy measurement takened as to simulate a reference level without shielding in place.
A procedure of using a radiation detection device to provide a measure rating for the shielding or blocking effectiveness measure of energy radiated electromagnetic fields as shown by indicating EMF energy reducing fashion is referred to as the method of shielding effectiveness figure-of-merit measure. Said method of shielding effectiveness figure-of-merit measure, is in more simple discussion terms referred to as the method. Said method is stated by the decibel value rating comprising the ratio equating formula of electromagnetic field strength measurement takened before and after shielding is in place or measurement takened without and with shielding in place, as prescribed by said radiation detection verification methodology comprising of said first test mode and said second test mode. Whereby, said method give results in providing a protective radiation monitoring detection ratio value and displayed accordingly to the previously mentioned specification. Also recognized is, of said decibel value rating, an alternative formula expression to the decibel value rating specification may also be restated in magnitude value rating specification for ease of the user&apos;s shield effectiveness measure and interpretation. The method by which shielding effectiveness and radiation detection may be estimated is the transmission line method and circuit method, published by the IEEE, 1988 “Special issue on electromagnetic shielding”, IEEE Transactions on EMC, EMC-30, No. 3, August.

Said remote-able RF sniffing probe option device with predetermined calibration setting provides the user with un-shielded radiation detection device measurement capability for means of determining the presence of EMF energy radiated emission and for acquiring perceptible measuring threshold presence of predetermined EMF energy radiated emissions within close proximity of the unprotected or un-shielded surrounding environment.
In close-proximity electromagnetic field radiation exposure to the user, the invention variation of FIG. 7a is a perspective view of a RF shielded wearable garment device joined in predetermined coplanar fashion means with embedding/non-embedding fashion means of a radiation detection device comprising of general construction layout using a feed-through construction attachment means 825 to employ a air vent access hole 830, is referred to as Option 7a of a integrated shield detection device.

Where said shield effectiveness detection monitoring comprising of shielding effective area 15 as is monitored by the radiation detection device for EMF energy exposure levels to direct line-of-sight EMF radiation 51,53 emanating from a wireless transmit/receive electronic equipment antenna 22.
Likewise in another alternative embodiment, in FIG. 7b the user may wear the RF shielded baseball cap 10 design in a different manner of orientation over the head that will provide various shield protection and shield effectiveness detection monitoring, is referred to as Option 7b of a integrated shield detection device.

As will be disclosed, shown in FIGS. 7a and 7b according to the invention, potential harmful direct line-of-sight EMF energy radiation 51, 53, 55 are shielded or blocked by the shielding arrangement and monitored to detect for presence of leakage EMF energy through the RF shielded wearable garment by said radiation detection device.
With respect to FIGS. 7a, 7b and 7c, examples of shielded or blocked or deflected electromagnetic fields 51 to 52, 53 to 54, 55 to 56 and non-blocked electromagnetic fields 30, 31, 32, 33 are shown to demonstrate the ideal radiation shielding device nature by assuming that geometrical theory of diffraction (GTD) on EMF plane waves applies for the blocked or deflected and non-blocked EMF cases and thereby no further disclosure is required. But in a more practical manner, EMF energy leakage through shielding devices does exist, which cannot be excluded or discounted by GTD.
Subsequently, a normal operation of said blocked EMF radiation, is measured using said second test mode.
