The present invention relates to devices for use in hazardous material applications, and more particularly, to a handheld measurement, search and safety device that is equipped with a variety of different field surveying instruments and tactical accessories, and field instruments to survey objects, people, vehicles, terrain, and buildings, from a distance or in confined areas, to detect, locate, measure, analyze, collect, identify, or monitor hazardous materials including radioisotope/radioactive materials or toxic chemicals.
Emergency personnel and first responders are well-trained individuals that are often called upon to assist individuals, or to manage unsafe conditions in life-threatening or dangerous situations. The efforts of public safety personnel, such as public health officials or health physics specialists are also solicited in particular circumstances to access various situations and conditions that may adversely affect the safety and well-being of people. One particular happenstance involves exposure of dangerous hazardous materials that may include toxic chemicals, such as anthrax, or deadly radioactive materials to humans and the surrounding environment. First responders and police officers are often trained to follow prescribed protocols while dealing with dangerous substances, often calling on the local fire marshal, and other public health officials to further access and manage both presence of, and possible exposure to, such hazardous materials. Most firefighting companies, and other public safety agencies, are typically educated and trained to also follow prescribed protocols when responding to hazmat situations. In many hazardous situations, chemical hazards often emanate pungent smells that are often associated with visually identifiable solids, liquids, or gases. Yet another hazard of grave concern includes the presence of radioactive or radioisotope materials that can rise to unacceptable or dangerous levels posing unknowing damage, such as gamma rays, to humans or animals. The presence of such radioactive substances is generally deemed more deadly or omniscient, because radioactive materials are not detectable by one's senses, unlike the case with most chemical hazards. Radiation cannot be seen, heard, smelled, tasted, or felt, so simple inspection is insufficient to locate and identify radioactive materials. It is common knowledge that exposure to even low levels of certain types of radiation has been proven to cause cancer, birth defects, and a host of adverse medical conditions. Emergency responders are generally held to a higher standard of training when dealing with radioactive materials; yet they are often holding radiation detection instruments with their bare hands. Use of radioactive materials is often seen in industrial applications, in research and development, manufacturing processes, in hospitals, as well as, on a much larger scale, in nuclear power plant or reactor operations and plant decommissioning. As such, the safety of well-trained personnel performing tasks associated with radioactive materials is a matter of concern in military, industrial, healthcare, and nuclear power plant radiation applications.
There are various aspects of individual and environmental safety concerns when dealing with possible exposure to hazardous materials. First and foremost is the safety of emergency responders, public bystanders, animals, and the surrounding environment. In the context of radioactive materials, public safety personnel are often poised with the task of identifying, detecting, or measuring various objects or targets to determine whether a radioactive material is present at all before implementing proper containment and/or disposal management practices. There are situations in which well-trained personal employ radiation detection tools to survey suspicious individuals, packages, vehicles, buildings, bags or purses, shoes, terrain, or other areas in an effort to determine whether radioactive materials are present. With the ongoing concern of terrorist acts, it is not uncommon to see law enforcement and homeland security employ techniques to locate radioactive materials that may be present in bags or on people in airports, on people or in vehicles at border crossings, or even in packages designated for the post office. It is also vital to identify, detect, and measure radioactive materials that are often associated with the decommissioning of power plants, use of radiological dispersal devices, or in preventative radiological nuclear detection missions for detecting, locating, and identifying radioactive material outside of regulatory control. Thus, there is an on-going concern and need to survey decommissioned nuclear power plant component parts, tools, and materials, containment of buildings and in civil society the surrounding environment, monitor people, equipment, vehicles, and a variety of different objects for radioactive contamination in various known and unknown applications
Safety personnel are generally equipped with standard tools and equipment to protect themselves from possible exposure to harsh, dangerous, and possibly life-threatening substances and chemicals. For example, responders often use protective barriers such as suits, hoods, gloves, and face shields to prevent hazardous materials from coming into contact with a person's eyes, hair, or skin. Pulmonary ventilation devices, such as, gas masks, or oxygen tanks, are also used to ventilate personnel and prevent inhalation of toxic chemical fumes or gases, or to oxygenate individuals who are exposed to such gases or fumes. There are a host of tools that are available to better assist personnel in dealing with hazardous materials attributed to radioactive materials. Because radioactive materials emanate no order, provide no sounds, and are invisible to the naked eye, special tools or devices have been developed to meet the challenges facing responders in detecting and identifying radioactive materials.
Many devices often entail small, handheld devices that comprise survey meters often referred to as radioisotope identification devices, known simply as RIID. Although such meters are effective in measuring or detecting gamma wave radiation, such devices are designed for a single purpose, and is typically held in a responder's hand during use. The responders typically hold RIID devices in one hand when surveying objects with the device, and as such, come in close proximity to surveyed objects in order to effectively determine whether hazardous materials are present. In doing so, responders bear the risk of exposing their hands to radioactive or chemical substances in the process as a result of being in close distance to target objects. The effort is exacerbated as responders often find themselves working in uncomfortable, awkward positions or places, maneuvering between objects, or searching in confined areas resulting in workers straining muscles, becoming imbalanced, and coming into contact with the hazardous materials tested. Prior art devices developed to assist responders in dealing with hazardous materials are generally designed for a single purpose. Also, such prior art devices do not offer the ability for responders to interchange different surveying tools or tactical accessories when on job sites, while at the same time, providing a tool for holding field survey instruments and eliminating the need of holding field survey instruments in hand. Further, prior art devices do not provide a tool for use in hazmat applications that allow responders to take distant measurements of surveyed objects and coordinate the measured data for evidentiary proceedings.
Accordingly, there is an established need for a solution to at least one of the aforementioned problems. There remains a need for a device that improves ergonomics by increasing comfort, balance, posture, and safety for responders when surveying targets for hazardous materials, while extending the reach and distance between first responders and hazardous materials to mitigate dangerous proximity to toxic chemicals or radioactive materials. There is also a need for a device that permits first responders to interchange a host of different field survey instruments and tactical accessories on-site to effectively detect, measure, identify, and locate hazardous materials, and to make measurements of surveyed objects for use in evidentiary proceedings, from a safe distance.
The present invention is directed to a handheld measurement, search and safety device that includes a main frame having a handle, an extendable member that slides outwards from the main frame, and an interchangeable support brace comprising a buttstock to provide a two-handed configuration in which the extendable member is used to survey objects, or a one-handed configuration in which the extendable member is removed and the main frame alone is used to survey objects in confined areas with an arm brace for stability.

Shown throughout the figures, the present invention is directed to a handheld measurement, search and safety device including a main frame having an ergonomic handle, an extendable member removably coupled to the main frame for mounting a variety of tactical accessories, a plurality of picatinny rails provided on the main frame, and field survey instruments for surveying people or objects, and an interchangeable support brace including an arm brace and a buttstock for handling the device with one or two hands during use.
Referring now to the figures wherein like numerals are represented by like elements throughout, there are shown in
A handle 104 is permanently or adjustably attached near the proximate end of the main frame 102 to accommodate holding the handheld measurement, search and safety device 100 in hand, and in at least one embodiment, the handle comprises an ergonomic configuration. As shown, the handle 104 includes a series of indentations 122 that are provided within the body of the handle 104 to conform to the phalange regions of a user's fingers to enhance comfort and provide firm gripping when holding the handle 104 during use. The handle 104 may be integrally formed with, or over-molded on, the body of the main frame 102, or separately attached directly to the body of the main frame 102. Alternatively, the handle 104 can be mounted onto a picatinny rail, via a quick release mount, where the picatinny rail is disposed on the lower, bottom surface of the main frame 102. The handle 102 may be covered or coated with, a durable rubber, foam, or polymer material, and include frictional properties such as dimples, grooves, ridges, or protrusions that are formed or provided on the outer surface of the handle 104 to prevent the handle 104 from slipping in a person's hand when navigating with the handheld measurement, search and safety device 100. It is understood that a forehand handle (not shown) may be removably mounted to the picatinny rail 112 to further accommodate a two-handle configuration in which users grasp both handles with both hands when maneuvering the handheld measurement, search and safety device 100 with the extendable member 114 in use. The added forehand handle may provide a beneficial feature when employing a buttstock 116.
With continued reference to
In accordance with at least one embodiment of the present invention, an elongated member 114 comprises a plurality of measurement indices which permit a user to quickly and easily determine an extended length of the device 100. As used herein, an extended length may be either an overall length of the device 100 from end to end, or a length from a fixed location on the device 100 to a particular filed survey instrument or tactical accessory operatively mounted to the device 100. In one embodiment of a handheld measurement, search and safety device 100, a plurality of measurement indices comprise a series of holes 126 formed through one or more walls of the rectangular body 124 and disposed in sequence along a predetermined length of the extendable member 114. The holes 126 are formed to reduce the weight of the handheld measurement, search and safety device 100 thus making it easier and more agile for personnel to maneuver and navigate the device 100 during use. The plurality of holes 126 are also employed for the intended purposes of distance measurement applications in the field. The plurality of holes 126 are positioned a predetermined distance apart from each other, at one-inch-on-center increments, to serve as position indicators, transforming the extendable member 114 into a measuring bar when extended. A one-inch-on-center may be represented as one hole equals one click equals one inch. The measurement configuration is intended to provide an easy and quick indication for even the least trained responder to understand and apply when working on a job site. The present embodiment is not limited to formation or use of the plurality of holes 126 and as such, as in one alternative embodiment, the extendable member 114 may comprise a solid or hollow rectangular body 124 without holes 126. It may be beneficial for the handheld measurement, search and safety device 100 to include measurement indicators to further pronounce identification of measurements in conjunction with the holes 106. As such, a series of measurement indicators may be imparted on the body 124 of the extendable member 114. Such measurement indicators may comprise, for example, marks, lines, symbols, or indicia that is formed within, or attached separately to, the outer surface of the elongate member 114 at designated locations adjacent each hole 106. A sequence of marks or lines may denote measurements in, millimeters, centimeters, inches, or fractions of inches. Also, although the extendable member 114 is illustrated as being a single piece, it is appreciated that the extendable member 114 may comprise a series of individual pieces, each having a rectangular body in which the rectangular pieces are dimensioned to individually slide one inside the other to provide for a telescoping extendable member 114 where the individual telescoping pieces are releasably locked in various positions or lengths from the main frame 102.
In one embodiment, the extendable member 114 includes any number of picatinny rails 128, 140 that are provided for example, at the distal end of the body 124, either on the top surface as show in
In one embodiment, the handheld measurement, search and safety device 100 includes an interchangeable support brace that gives responders a tactical benefit of using the device 100 when surveying objects, whether in a one-handed or a two-handed configuration, each amendable to particular applications. Utility of the extendable member 114 allows responders to reach out further when surveying or searching people, vehicles, facilities, or terrain with field survey instruments for hazardous materials, but the added weight of the extendable member 114 imposes a need for properly handling the handheld measurement, search and safety device 100 in such situations. For two-handed applications, the handheld measurement, search and safety device 100 includes a buttstock 116 that is mounted to the proximate end of the main frame 102, as illustrated in
To assist responders in carrying and transporting the handheld measurement, search and safety device 100, a strap buckle 138 is affixed to the buttstock 116 to permit attaching an adjustable handle strap, or an adjustable shoulder strap (not shown) for securement to a person's shoulder. It will be understood that one or more buckles may be provided anywhere on either the main frame 102 or extendable member 114, or both, to attach one end of an adjustable shoulder strap to the strap buckle 134 and another end to the one or more added buckles. The shoulder strap may comprise any well-known shoulder strap that is typically used with firearms.
A host of handheld field survey instruments, and other tactical accessories, are used, alone or in combination, to perform various functions when detecting, identifying, locating, monitoring, sampling, collecting, transporting or dealing with hazardous materials in the field. For example, there are a number of devices or instruments that are used specifically to survey toxic chemicals, and radioactive materials in potentially dangerous environments. Mounting such handheld field survey instruments, or tactical accessories onto the main frame 102, or extendable member 114, enables trained personnel or responders to gain greater access over distances and eliminate the common practice of surveying dangerous hazmat materials with handheld instruments or accessories. As such, providing a mounting platform for field instruments and tactical accessories increases safety by eliminating the need for individuals to use their hands when holding instruments in close proximity to hazardous materials, and increases distance between the user and radioactive materials that may be present in or on, surveyed objects, people, vehicles, or packages. The handheld measurement, search and safety device 100 helps alleviate the fear of responders exposing their hands to possible danger, or coming in close proximity or in contact with hazardous materials. In practice, a variety of different field survey instruments, or tactical accessories, include but are in no manner limited to: a tape measure, flashlight, sample collection devices, hooks, claws, clamps, snips, tweezers, needles, pipets, syringes, swabs, loops, socket tools, screw drivers, four-star screw driver, wrench, mirror, visual contrast plate, laser, rangefinder, lasers, camera, video camera, shield, cable, rope. Geiger counter, radiation isotope identification and quantification device (RIID), metal detector, alpha/beta gamma radiation detector, magnet, container, cup, marking devices, smart phone, transmitter, receiver, transceiver, spectrometer, ultraviolet light, top platform, brush, sponge, large swab, or any combination thereof.
The handheld measurement, search and safety device 100 provides the ability to easily and quickly mount and interchange any of the field survey instruments, and/or tactical accessories, for use in hazmat applications. One exemplary mount used for employing field survey instrument comprises a cylindrical instrument mount, generally denoted at 200 in
With reference to
There likely will be situations when trained personnel or responders will assume a prone, kneeling, or laying position when surveying objects in hazmat applications or conditions. The handheld measurement, search and safety device 100 accommodates such positional use by allowing responders to easily, and quickly install a stabilizer, such as a bi-pod 500 to stabilize the handheld measurement, search and safety device 100 in a generally horizontal position. The practical use of the bi-pod 500 is beneficial when using the handheld measurement, search and safety device 100 for distance measurement applications in support of evidentiary materials. As shown in
Turning now to
As shown in
In one further embodiment, the measuring tape 702 is extracted from the measuring tape line 700 for a measurement distance earmarked as forty inches. More in particular forty inches is an important measurement because it is as close to one meter as emergency field personnel are going to measure in most practical applications. The distance of forty inches is the distance taught in federal first responder training manuals and curricula. Precise distance measurement is critical for spectral analysis of unknown radionuclides and isotopes. Secondary screeners who utilize the handheld measurement, search and safety device 100 measurement system will send data and information to scientists who will analyze gamma spectra of unknown radionuclides/isotopes in an effort to positively identify the unknown materials surveyed. This process is often referred to as reach-back. Reach-back is typically used for law enforcement purposes, e.g., criminal prosecution. As such, the handheld measurement, search and safety device 100 provides a measurement application tool and system used to help gather and provide forensic evidentiary measurements which is of great value in legal proceedings. The plurality of holes 126 provided in the extendable member 114 assist in making and determining such measurements as they are, in one embodiment, positioned apart from each other at one-inch-on-center increments and serve as a positive indicator transforming the extendable member 114 into a measuring bar when extended outwards from the main frame 102. As such, the measuring tape line 700 and plurality of holes 126 provided on the extendable member 114, both serve as positive methods of measuring distances in the field. As will be appreciated, a measuring tape line 700 may be incorporated in combination with any embodiment of a handheld measurement, search and safety device 100 in accordance with the present invention.
With reference now made to
The arm brace 142 allows responders to navigate and maneuver the handheld measurement, search and safety device 100 with one hand by easily and quickly positioning the brace body 146 onto the person's forearm while grasping and holding the handle 104 in one hand, with the phalanges of the fingers disposed securely within the finger recesses 122 provided within the handle 104, as illustrated in
With reference made to
A host of different tactical accessories are compatible for use with the handheld measurement, search and safety device 100 as well. For example, trained personnel may have to survey objects, vehicles, or terrain in low lit or dark areas. To overcome this challenge, responders can easily mount a flashlight anywhere on either or both the extendable member 114, or main frame 102, via, picatinny rails 128, 140, 106, 108, 110, 112, 113, 128 and 140 to illuminate the forward direction of trained users and effectively illuminate any surveyed object, person, or target. Still, other applications may require responders to take pictures, determine distances afar, take samples, or check under vehicles for example. In doing so, responders may mount a camera, rangefinder, grippers, and a mirror to the handheld measurement, search and safety device 100 via, any of the picatinny rails provided on either or both the elongate member 114 or main frame 102 giving responders optimum tools needed in hazmat applications. Any combination of tactical accessories and field survey instruments are used with the handheld measurement, search and safety device 100 when surveying objects, people, buildings, vehicles, or terrain for hazardous materials including toxic chemicals, and radioactive materials.
Another important accessory that comports with the main frame 102 is a removable lead shield. In one embodiment, the lead shield comprises a circular shape resembling a common dinner plate. The thickness of the shield may vary based on weight requirements. The standard thickness would be set at ⅛ of an inch. A stiffening backing may be attached to the lead shield to stiffen the pliable nature of the lead material used. Multiple shield plates may be stacked so as to provide additional protection as warranted by calculations. A cut-out will allow each shield to be mounted to the main frame 102 from below by means of a quick release picatinny style connector. The purpose of the cut-out is to allow for direct visual line of sight between the operator and the radiation detector which is mounted at the distal end of the device. The purpose of combining the shield accessory with the radiation detector while the handheld measurement, search and safety device 100 is used in a two-handed configuration is to protect the operator to the greatest degree practicable from ionizing radiation.
It is understood that various modifications or additional features may be made to, or provided with, the handheld measurement, search and safety device 100 without departing from the scope of the invention. For example, it is contemplated that although the main frame 102, and extendable member 114 are depicted as each comprising a generally rectangular body 118, 126, the geometrical shape of the main frame 102 and extendable member 114 may each comprise a round, tubular body where an extendable tube member 114 comprises a slightly smaller diameter than a main tube frame 102 to permit the extendable tube member 114 to adjustably slide within the main tube frame 102.
As shown in the figures, the main frame 1102 generally comprises an elongate body 1118 having a predetermined length and comprising a plurality of walls that are integrally joined together to form an elongate channel 1120 that extends a predetermined length within the elongate body 1118. Also as before, each picatinny rail 1106, 1108, 1110, 1112, 1113 comprises any one of a number of lengths, and is permanently, or temporarily affixed to any surface of the four walls of the rectangular member 1118, and may extend the full length, or a partial length of the body 1118. Once again, exemplary embodiments of mounting rails include picatinny rails, however, it will be understood that other accessory mounting rails may be employed, including, but not limited to, weaver, keymod, and M-LOK® rails. It will also be appreciated that any combination of rails can be used on the main frame 1102, extendable member 1114, or both. As such, a combination of picatinny rails and weaver rails may be employed, or M-LOK® rails and picatinny rails as another example may be implemented without departing from the scope and intent of the present invention.
As before, it is well understood that although the main frame 1102 and extendable member 1114 are depicted as each comprising a generally rectangular body 1118, 1124, the geometrical shape of the main frame 1102 and extendable member 1114 may each comprise a round, tubular body where an extendable member 1114 comprises a slightly smaller diameter than a main frame 1102, once again, to permit the extendable member 1114 to be adjustably extended outwardly of and away from the main frame 1102 while in use, and to be retracted back into the channel 1120 of the main frame 1102 when not in use.
As before, a handle 1104 may be either permanently or releasably attached near the proximate end of the main frame 1102 to accommodate holding the handheld measurement, search and safety device 1000 in one's hand, and also as before, in at least one embodiment, the handle 1104 comprises an ergonomic configuration. As shown by way of example in
With continued reference to
As before, in accordance with at least one embodiment of the present invention, an elongated member 1114 comprises a plurality of measurement indices which permit a user to quickly and easily determine an extended length of the device 1000. Also as before, as used herein, an extended length may be either an overall length of the device 1000 from end to end, or a length from a fixed location on the device 1000 to a particular filed survey instrument or tactical accessory operatively mounted to the device 1000. In one embodiment of a handheld measurement, search and safety device 1000, a plurality of measurement indices comprise a plurality of marks 1126 formed along at least one side and disposed in sequence along a length of the body 1124 of the extendable member 1114. The marks 1126 are provided to facilitate distance measurement applications in the field. The plurality of marks 1126 are positioned a predetermined interval apart from each other, such as, by way of example only, at one-inch intervals, so as to serve as position indicators, thereby transforming the extendable member 1114 into a measuring bar, when extended forward from or retracted backward into the channel 1120 of the main frame 1102, such as is shown by way of example by the directional arrow in
More in particular, in at least one embodiment, as noted above, the present handheld measurement, search and safety device 1000 comprises a measurement collar 1132 coupled to a main frame 1102. As may be seen from the figures, a measurement collar 1132 includes a measurement display window 1134, wherein at least a portion of an extendable member 1114 disposed in the channel 1120 of the main frame 1102 is visible through the measurement display window 1134. Further, and as before, in at least one embodiment, the extendable member 1114 of the handheld measurement, search and safety device 1000 includes a plurality of marks 1126 disposed along the body 1124 of the extendable member 1114, such as is shown by way of example in
In at least one embodiment, the plurality of marks 1126 are utilized to denote a measurement distance of forty inches. Once again, and as before, forty inches is an important measurement because it is as close to one meter as emergency field personnel are likely able to practically measure in the field in most applications, and, more importantly, a distance of forty inches is the distance taught in federal first responder training manuals and curricula as the minimum safe distance from which certain measurements should be taken. As another example, precise distance measurement is critical for spectral analysis of unknown radionuclides and isotopes. As such, the present handheld measurement, search and safety device 1000 allows a user to gather and provide forensic evidentiary measurements which is of great value in legal proceedings. The plurality of marks 1126 provided on the extendable member 1114 assist in making and determining such measurements as they are, in one embodiment, positioned apart from each other at predetermined intervals, such as, one-inch intervals, and thus serve as a positive indicator transforming the extendable member 1114 into a measuring bar when extended outwards from the main frame 1102. In at least one embodiment, the present handheld measurement, search and safety device 1000 further comprises a tape measuring line 700 which may be utilized in conjunction with the plurality of marks 1126 provided on the extendable member 1114, both serving and confirming positive measurement of distances in the field. As will be appreciated, once again, a measuring tape line 700 may be incorporated in combination with any embodiment of a handheld measurement, search and safety device 1000 in accordance with the present invention.
As before, although the extendable member 1114 is illustrated as being a single piece, it is appreciated that the extendable member 1114 may comprise a series of individual pieces, each having a body dimensioned to individually slide one inside the other to provide for a telescoping extendable member 1114, wherein the individual telescoping pieces are releasably secured in various positions or lengths while extended from the main frame 1102.
Also as before, in at least one embodiment, the extendable member 1114 includes one or more picatinny rails 1128 provided at the distal end of the body 1124, for example, on the top surface as show in
In one embodiment, the handheld measurement, search and safety device 1000 in accordance with the present invention includes a number of field instruments or tactical accessories, each amendable to one or more particular applications, such as may be seen, by way of example, in the alternative illustrative embodiment of
As will be appreciated, while the utility of the extendable member 1114 allows responders to reach out from a safe distance when surveying or searching people, vehicles, facilities, or terrain with field survey instruments for hazardous materials, in some cases the added weight of the extendable member 1114 and/or field instruments or tactical accessories imposes a need for assistance in handling the handheld measurement, search and safety device 1000 in such situations. As such, in at least one embodiment, the handheld measurement, search and safety device 1000 includes a buttstock 1116 that is mounted to the proximate end of the main frame 1102, as illustrated in
In at least one embodiment, either or both the main frame 1102 and/or the extendable member 1114 may comprise a plurality of holes there through so as to reduce the overall weight of a handheld measurement, search and safety device 1000 in accordance with the present invention, such as, by way of example, the holes 126 formed through the extendable member 114 of the handheld measurement, search and safety device 100 such as is shown, for example, in the illustrative embodiment of
Once again, and as previously stated, a host of handheld field survey instruments, and other tactical accessories, are used, alone or in combination, to perform various functions when detecting, identifying, locating, monitoring, sampling, collecting, transporting or dealing with hazardous materials in the field. For example, there are a number of devices or instruments that are used specifically to survey toxic chemicals, and radioactive materials in potentially dangerous environments. Mounting such handheld field survey instruments, or tactical accessories onto the main frame 1102, or the extendable member 1114, enables trained personnel or responders to gain greater access over distances and eliminate the common practice of surveying dangerous hazmat materials with handheld instruments or accessories. As such, providing a device on which to mount various field instruments and tactical accessories increases safety by eliminating the need for individuals to use their hands when holding instruments in close proximity to hazardous materials, and increases distance between the user and radioactive materials that may be present in or on, surveyed objects, people, vehicles, or packages. The handheld measurement, search and safety device 1000 helps alleviate the fear of responders exposing their hands to possible danger, or coming in close proximity or in contact with hazardous materials. In practice, a variety of different field survey instruments, or tactical accessories, include but are in no manner limited to: tape measures, flashlights, sample collection devices, hooks, claws, clamps, snips, tweezers, needles, pipets, syringes, swabs, loops, socket tools, screw drivers, four-star screw drivers, wrenches, mirrors, visual contrast plates, lasers, rangefinder, lasers, cameras, video cameras, shields, cables, ropes, Geiger counters, radiation isotope identification and quantification devices (RID), metal detectors, alpha/beta gamma radiation detectors, magnets, containers, cups, marking devices, smart phones, transmitters, receivers, transceivers, spectrometers, ultraviolet lights, platforms, brushes, sponges, large swabs, or any combination thereof.
The present handheld measurement, search and safety device 1000 provides the ability to quickly and easily mount and interchange any of the field survey instruments, and/or tactical accessories, for use in hazmat applications. One exemplary mount used for employing field survey instrument comprises a cylindrical instrument mount 1200, as shown in

As before, the brace body 1146 includes a generally C-shaped member adapted for quickly and easily installing the brace body 1146 onto a person's forearm. In one non-limiting embodiment, the brace body 1146 may comprise a flexible, plastic material that resiliently expands or flexes outwardly apart to permit mounting the brace body 1146 on individuals with larger forearms. It will be noted however, that the brace body 1146 may also comprise a fully, enclosed or encircled brace in which responders insert one hand into the hollow region of the enclosed or encircled brace, and then grasp the handle 1104 with one hand. It will be understood that the brace extension 1144 may comprises any geometric shape such as round, or rectangular, and may also include a telescoping mechanism that allows users to adjust the length of the brace extension 1144 during use. It will be understood that any of a number of brace bodies 1146 may be used as well.
The arm brace 1142 allows responders to navigate and maneuver the handheld measurement, search and safety device 1000 with one hand by quickly and easily positioning the brace body 1146 onto the person's forearm while grasping and holding the handle 1104 in one hand via the grip 1122. In using one hand, first responders can easily and quickly survey objects, with a field survey device such as a radioisotope identification device (RIID) 1300 to measure, detect or identify different forms of radiation including alpha and/or gamma radiation materials that may be present. The objects to be surveyed, for example, may be situated within a small, confined room, area, or space that would make use of the extendable member 1114 impractical or simply not possible, and as such, an arm brace 1142 is provided wherein responders can survey objects or people at shorter distances and within smaller, confined areas, with or without the use of the extendable member 1114. The brace body 1146 may include foam or rubber padding or cushion to enhance comfort and to lessen pressured impact of the brace against a user's arm during use. It is contemplated that to further steady the handheld measurement, search and safety device 1000 against a responder's forearm during use, the arm brace 1142 may include a short, adjustable strap to attach the brace body 1146 to a user's forearm. As one example, a short, adjustable strap may extend between opposite, lateral edges of the brace body 1146, and include buttons, buckles, hook and loop type fasteners, rings, magnets, or other fasteners for attaching the strap in place.
To assist responders in carrying and transporting the handheld measurement, search and safety device 1000, in one embodiment, a buttstock 1116 includes a strap mount 1804 to permit a strap 1802 to be attached thereto, such as is shown in
As before, a host of different tactical accessories are compatible for use with a handheld measurement, search and safety device 1000 as well. For example, trained personnel may have to survey objects, vehicles, or terrain in low lit or dark areas. To overcome this challenge, responders can easily mount a flashlight anywhere on either or both the main frame 1102 or the extendable member 1114 via one or more of picatinny rails 1106, 1108, 1110, 1112, 1113 or 1128, so as to illuminate the forward direction of trained users and effectively illuminate any surveyed object, person, or target. Still, other applications may require responders to take pictures, determine distances afar, take samples, or check under vehicles for example. In doing so, responders may mount a camera, rangefinder, grippers, and a mirror to the handheld measurement, search and safety device 1000 via any of the picatinny rails provided on either or both the main frame 1102 or the extendable member 1114 giving responders optimum tools needed in hazmat applications. Any combination of tactical accessories and field survey instruments are used with the handheld measurement, search and safety device 1000 when surveying objects, people, buildings, vehicles, or terrain for hazardous materials including toxic chemicals, and radioactive materials.
