The content of each of the above-described patents and applications is incorporated by reference herein in its entirety. The above applications may be collectively denoted herein as the “co-assigned applications” or “incorporated applications.”

[0041] The following exemplary embodiments are provided for the purpose of illustrating examples of various aspects, details, and functions of devices, apparatus, and systems; however, the described embodiments are not intended to be in any way limiting. It will be apparent to one of ordinary skill in the art that various aspects may be implemented in other embodiments within the spirit and scope of the present disclosure.

[0042] It is noted that as used herein, the term, "exemplary" means "serving as an example, instance, or illustration." Any aspect, detail, function, implementation, and / or embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects and / or embodiments.Example Embodiments

[0043] FIG. 1 illustrates an exemplary electronics module embodiment 100 (also referred to herein as just a “module” for brevity). Module embodiment 100 is in the form of a Bluetooth™ wireless transceiver module, however, various other electronic circuitry can be implemented on alternate module embodiments in accordance with aspects of the disclosure and in applications such as those described previously herein, as well as other devices and applications.S EEK 09 -452 -40 1 S PE C S C I Pe v 1 16 P C T Pa ten t A pplica tion

[0044] Module 100 comprises a housing 120 (which can function as a case or shield as well as a mechanical mounting mechanism for other module components) as well as an electronic printed circuit board or boards 140 (also denoted herein as a “PCB” for brevity). As noted above in the example of FIG. 1 the electronic circuit on PCB 140 implements a Bluetooth transceiver, however, any of various other electronic circuits or combinations of circuits and / or other elements may be implemented in different module embodiments.

[0045] A United States quarter dollar is also shown in FIG. 1 to illustrate the relative size of an exemplary module embodiment. It is noted, however, that alternate embodiments may be implemented in larger or smaller sizes, as well as different shapes, shielding configurations, included electronic circuit or circuits, additional elements such as mechanical components, optical components, electromagnetic components, and the like may also be included.

[0046] In exemplary module systems, it may be desirable to define a standard module shape, size, connector pinout(s), and other parameters to facilitate ready interchangeability and / or manufacturability of associated systems in which such modules are placed. Some examples of this are described subsequently herein in conjunction with the drawing figures.

[0047] FIG. 2 illustrates additional details of module embodiment 100 in an exploded or disassembled view. PCB embodiment 140 may be a circuit board and associated components that are mounted in housing 120 using, for example, screws 221 or other attachment mechanisms (i.e., in this example eight screws are used, however, other embodiments may use different number of screw or other attachment mechanisms in different configurations). PCB embodiment 140 may implement any of various types of electronic circuitry or functions, such as wireless transceivers, signal processing circuits, analog circuitry, microprocessor circuitry, and / or other types of electronic circuits or hybrid electronic, optical, and / or mechanical functions.

[0048] PCB embodiment 140 may include one or more circuit boards, such as printed circuit board (“PCB”) 242 as shown, as well as one or more electronic, electromechanical, optical, or other components on the PCB, as well as electrical connectors, such as connector 244 as shown in FIG 2, to couple electronic signals and / or power to or from the electronic circuit board, as well as other electrical, mechanical, or optical components or assemblies. Some embodiments mayS EEK 09 -452 -40 1 S PE C S C I Pe v 1 17 P C T Pa ten t A pplica tioninclude optical connectors to couple fiber optic cables to the PCB and / or other types of connectors as are known or developed in the art.

[0049] In exemplary embodiments, modules may be configured based on defined standard connector types and locations so as to allow for interconnectivity of different module types within a system using the same connector or connectors. Examples of this are described subsequently herein with respect to, for example, FIG. 9A and FIG 9B as well as FIG. 14 (where module embodiments are mounted or mountable on other electronic device circuit boards or assemblies).

[0050] The PCB and / or housing of various module embodiments may include mechanical features to facilitate fast and accurate registration of electronic connector(s) to associated interfaces such as cables with matching pinouts, additional connectors, or other electronic interface elements such as are described subsequently herein.

[0051] Exemplary module housings, such as housing embodiment 120 as shown in FIG. 1 and 2, may be formed or created by injection molding of plastic resin materials such as shown in FIG.3 and FIG. 4 and as described subsequently herein.

[0052] Referring again to FIG. 2, housing embodiment 120 may include an interior volume 222, in which circuit board such as PCB 140 and / or other components may be installed or placed. The housing embodiment may have a top or upper side 226 (underneath the housing embodiment 120 as shown in FIG. 2 and also shown on the top in FIG. 5B) which may be solid or may include holes or other openings such as shown in FIG. 2. The housing embodiment may also have a bottom or lower side 224, which is open in the embodiment as shown in FIG. 2, but may include a cover or may be positioned adjacent a circuit board or other electronics component or assembly in various assembly and device embodiments (e.g., as shown in, for example, FIG 9A and FIG. 14).

[0053] In an exemplary embodiment, a housing such as housing embodiment 120 may be molded or otherwise formed or made in a rectangular box-like shape as shown in FIG. 2. The housing may have an open lower or bottom side and a solid upper or top side as shown. Some embodiments may have an opening on the upper or top side to allow a heat sink to be placed in the opening, such as, for example, is shown in FIG. 12A.S EEK 09 -452 -40 1 S PE C S C I Pe v 1 1 8 P C T Pa ten t A pplica tion

[0054] In alternate embodiments, rather than being injection molded from a plastic or polymer material, a module housing may be die-cast, vacuum formed, or manufactured using other current or future-developed manufacturing technologies and materials.

[0055] I some other embodiments a housing may have alternate shapes, such as cylindrical, spherical, or other shape configurations, dimensions, and / or proportions.

[0056] In manufacturing housing embodiments, it may be advantageous to injection mold them from a plastic or polymer (or other relevant material) and leave them on an injection molding runner system during the manufacturing process before singulating (i.e., separating the parts) the individual housings. This may be done, for example, to minimize handling of individual housings (and reducing associated defects or damage) or for other reasons. For example, by leaving all of the individual housing elements on the runner system a worker can grab the runner system to hold multiple elements (e.g., eight in an exemplary embodiment) while working with them. This may simplify optional additional manufacturing steps, such as plating of the modules, by allowing easier handling of the modules through the plating process, simplifying the overall process by plating (or otherwise processing) the individual parts before singulation.

[0057] One example of this is shown in FIG. 3, which illustrates two injection molded modules left on their runners in an example multiple housing array embodiment 300. Housing array embodiment 300 includes injection molded housing elements 320, with the individual elements 320 shown attached to typical injection molding runners 321, allowing for making multiple housing elements on a single mold.

[0058] In some embodiments, such as array 300 as shown in FIG. 3, the individual housing elements 320 may include numbering, such as numbers 323 as shown, or other markings or indicators to uniquely identify each housing element. Marking using numbers as shown in FIG. 3 may be use to show, for example, where in the mold each individual housing was molded, as well as other information such as a serial number of the mold they were formed on (not shown in FIG.3)-

[0059] As one example advantage of such marking, the numbering may be used during later testing to facilitate identifying problems with a mold (e.g., if multiple parts fail and they haveS EEK 09 -452 -40 1 S PE C S C I Pe v 1 19 P C T Pa ten t A pplica tionthe same number it may be indicative of a mold cavity problem on that particularly numbered cavity).

[0060] In exemplary embodiments a plateable resin may be used to make the housings. The individual housing elements may be then be plated (for example, while left on the array as shown in FIG. 3 and FIG. 4 or, in some embodiments, after separating them from the mold runners or other structures) for electromagnetic shielding, or for other reasons such as increased structural characteristics, insulating characteristics, conductivity characteristics, and the like using, for example, highly conductive metals such as copper, gold, silver, and / or other conductive or shielding materials.

[0061] By forming the housing elements with injection molding, plating of multiple housings may advantageously be done simultaneously, such as shown in multiple housing array embodiment 400 as shown in FIG. 4. Similar to housing array embodiment 300 shown in FIG. 3, housing array embodiment 400 includes multiple molded individual housing elements 420 along with typical runners 421. Modules 420 also include mold numberings 432. Modules 420 of array 400 as shown in FIG. 4 are plated with a highly electrically conductive surface layer around the entirely of the module to provide shielding, low resistance connectivity to PCBs or other module elements, low resistance mechanical connections (e.g., to screws or other mechanical assembly components) and the like.

[0062] When using plateable resins, all or part of housing array embodiment 400 may be plated as part of the manufacturing process. For example, depending on the molding and plating used, in some embodiments the entire array may be plated such as shown in FIG. 4. In other embodiments only part of the array may be plated; for example, only the individual housing elements may be plated, or in some embodiments only portion of the individual housing elements may be plated (not shown in FIG. 4).

[0063] In an exemplary embodiment the resin may comprise about 40 (forty) percent carbon fiber-filled Ultem resin (Ultem is a trademark for amorphous thermoplastic polyetherimide (PEI) material, see, e.g., https: / / www.sabic.com / en / products / specialties / ultem-resin-family-of- high-heat-solutions / ultem-resin). Use of carbon fiber makes the housing elements somewhat conductive.S EEK 09 -452 -40 1 S PE C S C I Pe v 1 20 P C T Pa ten t A pplica tion

[0064] In some embodiments the housing may be primarily or entirely metallic. For example, metal injection molding may be used or other metal fabrication methods may be used such as 3D printing, die cast, powdered metal laser sintered, and the like. In some of these alternately embodiments such as these metal housings may also be plated with metals or other materials.

[0065] FIG. 5 A illustrates additional details of the housing embodiment 120 as shown in FIG. 1 and FIG. 2. Housing embodiment 120 may include one or more PCB mounting bosses 521 as shown. These may be located along the ends, sides, or other positions, such as within the interior volume 222 of the housing. For example, in the embodiment shown in FIG. 5 two PCB mounting bosses 521 as shown on each of the four interior sides of the housing.

[0066] PCB mounting bosses may have their top sides recessed from the top of the housing as shown to allow a PCB or other mounted element of the module to sit at or below the top side surface of the housing, such as shown in FIG. 1 (slightly below the top surface in the example housing 120 in FIG. 1). In other embodiments various alternate numbers, sizes, and positions of PCB or other interior mounting bosses may be used depending on the number of circuit boards or other module configurations.

[0067] Additional mounting bosses may be used in various embodiments. For example, housing mounting bosses 523 may be included in the housing to facilitate attachment of the module to other system components, such as other circuit boards, mechanical assemblies, or other mounting places and positions within a module or associated apparatus or device. In example embodiment 120 as shown, two housing mounting bosses 523 are formed on the shorter sides of the housing with their top sides flush with the lower or bottom side, and three housing mounting bosses 523 are on the longer sides also flush with the lower or bottom side. In alternate housing embodiments different numbers, sizes, recesses from the lower or bottom side, and / or shapes of housing mounting bosses may be included.

[0068] Housing embodiments may include alignment pins or posts such as keying or alignment posts or pins 525 as shown in FIG. 5. These posts may be used to align the modules with other external system components such as other circuit boards, and / or with other components positioned in the interior volume of the housing or external to the housing.S EEK 09 -452 -40 1 S PE C S C I Pe v 1 21 P C T Pa ten t A pplica tion

[0069] Housing embodiments may include one or more keying ribs to facilitate alignment of components placed in the housing interior volume 222, such as keying rib 527 as shown in FIG. 5. Keying rib 527 protrudes from a side of the housing into the interior volume to engage a corresponding void in a component positioned within the volume, such as with correspondingly shaped opening 647 of PCB 140 as shown in FIG. 6A and FIG. 6B.

[0070] Similar functionality to the engagement of keying rib 527 and PCB opening 647 is shown in the alternate module embodiment 800 of FIG. 8A (with keying rib 827 and keying opening 847 of FIG. 8A). This keying and associated opening configuration may be used to prevent insertion of a PCB into a housing during assembly either upside-down or right-left reversed.

[0071] Additional keying mechanisms, such as keying pin 525, may be included to allow for registration with another element to which the module is attached, such as to another circuit board or other assembly or device element (e.g., a frame, other housing, additional PCB, and the like). This can aid in placing a module accurately within other assembly or device elements using standardized, predefined circuit board and connector layouts and associated mechanical configurations. Alternate embodiments may use ribs or other registration elements (Not shown) to facilitate keying of modules with other system elements.

[0072] Housing embodiments may include one or more holes or opening for components, cables, connectors, heat sinks, or other elements to pass-through. For example, housing embodiment 120 includes an opening 526 (as shown in FIG. 5 A) for pass-through connections to a U.FL (ultra-small, Hirose) connector, as well as opening 528 for pass-through or admitting an FCX connector.

[0073] Alternate module embodiments may include openings of other shapes, sizes, positions, and the like depending on pass-through needs for wires or components of the associated module.

[0074] FIG. 5B illustrated module embodiment 100 from a side view, with the upper or top side 226 of housing embodiment 120 shown on the top of the figure, and screws 221 securing PCB embodiment 140 inside of housing 120 (as such, PCB 140 is not visible). An antenna jack may be included, such as jack 543 which can be seen protruding from the back side of housing 120. The antenna jack or connector 543 (an FCX connector in the embodiment shown) may beS EEK 09 -452 -40 1 S PE C S C I Pe v 1 22 P C T Pa ten t A pplica tionused to, for example, position a Bluetooth, Wifi, or other antenna outside of the shielded volume with the module 100.

[0075] Antenna jack 543 is further illustrated in FIG. 6B on PCB embodiment 140, with the connector 543 passing through opening 528 as shown in FIG. 5A. Keying pin embodiment 525 is shown protruding from the front side 224 of housing 120 in FIG. 5B, and keying or other registration elements such as this may be used to properly align a module to another element such as another circuit board, frame, or other element of a system in which the module is installed.

[0076] FIG. 6A and FIG. 6B illustrate additional details of the PCB embodiment 140 as shown in FIG. 1 and FIG. 2. FIG. 6A illustrates the lower or bottom side of the PCB embodiment 140 (facing towards the open bottom of housing 120), and FIG. 6B illustrates the top or upper side of the PCB (facing towards the enclosed top side of the housing.

[0077] As noted previously, this example PCB embodiment 140 implements a BLE (Bluetooth Low Energy) circuit, however, the elements and functions described below may be implemented on electronic circuit of various types, sizes, and shapes in alternate embodiments.

[0078] As this embodiment 140 is a radio module, an antenna jack or connector 643 as described previously herein may be soldered to the PCB 140 or, in other embodiments, may be mounted on alternate PCBs or other connector or jack elements of a circuit.

[0079] PCB embodiments, such as embodiment 140 or other embodiments described subsequently herein, may include a ground plane or other conductive surface or volume with the plane flooded into a perimeter (or other) area, such as perimeter flood area 641 as shown in FIG. 6A and FIG. 6B. This conductive surface allows for a low resistance electrical contact between the flood area and the plated housing through use of screws, such as screws 221, through the flood area (or other conductive area) of PCB embodiment 140 to the housing 120, with the screws tightened sufficiently to provide a strong mechanical and electrical contact from the PCB to the plating of the housing.

[0080] Use of multiple screws may further improve the electrical contact between the housing and the PCB (or other internal housing component) by reducing resistance and / or path length, and may also be used to shape the shielding and ground profile of the module. In addition, if the housing is plated with an appropriate metal or other conductive material, solder connectionsS EEK 09 -452 -40 1 S PE C S C I Pe v 1 23 P C T Pa ten t A pplica tioncan be made directly between surfaces of the housing and solderable areas of the PCB, or between the module and other assembly or device electrical connection points.

[0081] In exemplary electronic modules, one or more electrical connectors may be used to operatively couple the module to associated assembly or device power and / or signal connections. For example, PCB embodiment 140 may include one or more electrical connectors, such as connector embodiment 240 as shown in FIG. 2 and FIG. 6, or other connector embodiments as described subsequently herein.

[0082] The PCB or other module connector or connectors may be positioned in a standardized defined position, such as a predefined standardized position on the PCB, so as to facilitate upgrading of the module with newer or alternate versions while maintaining a predefined mechanical position and electrical pinout. Using a predefined standardized connection position may also facilitate easy mounting of electronic modules on other assembly or device elements, such as additional circuit board as shown in, for example, FIG. 14, wherein module embodiment 1200 may be mounted to PCB 1492 of assembly 1490. Module 1220 mounts with its connectors 1244 attached to corresponding connectors 1494 of PCB 1492, with the module itself positioned with the dashed lined area 1495. PCB traces on PCB 1492 and PCB 1240 of module 1220 may be in tight contact to electrically couple the two areas and provide shielding completely around PCB 1240.

[0083] Connector 240 has a mechanical interface defined by its position on the PCB and relative to the housing and with respect to any keying or registration elements of the housing, as well as an electrical interface defined by the pinout, and a software interface defined by any associated APIs (application programming interfaces) or other software-defined interfaces. By standardizing these interfaces, modules of various types may be readily placed on other device or apparatus elements and / or readily interchanged with new or different modules with upgraded or different functionality.

[0084] FIG. 7A and FIG. 7B illustrate additional details of module embodiment 100 as assembled from the front or to side (FIG. 7A) and back or bottom side (FIG. 7B) of housing 140.

[0085] As shown in FIG. 7A, PCB 140 is mechanically and electrically bonded to plated housing 120 through direct contact with a boss on the housing (not shown in FIG. 7A, butS EEK 09 -452 -40 1 S PE C S C I Pe v 1 24 P C T Pa ten t A pplica tionillustrated in FIG.5 A as one of the bosses 521) as well as through contact with conductive screw 221 from the solder flooded area of PCB 140 to the plating of the boss (and housing itself if the housing is formed of metal or other conductive materials such as conductive resins) and through the plated back side of housing 120 as shown in FIG. 7B. PCB 140 is keyed to housing 120 through rib 527 of housing 120 and hole 647 of PCB 140. Connector 244 is positioned in a defined position within the module and module registration elements, such as pin 525. FIG. 7B shows the back or bottom side of housing 120, with antenna connector 543 passing through hole 528. As shown, there is no connector in opening 526, however, opening 526 may be molded as shown to receive a U.FL connector (as shown) or other connector type or opening in alternate embodiments (not shown).

[0086] FIG. 8A illustrates details of the bottom or lower side of a module embodiment 800. Module embodiment 800 includes four connectors 844 on PCB embodiment 840, rather than the single connector 244 as shown in module embodiment 100. Various other embodiments may include fewer or more connectors than those shown module embodiment 100 and module embodiment 800, and those connectors may be of different types and / or sizes and may be placed in other positions on corresponding PCBs or other circuit connection elements.

[0087] FIG. 8B illustrates additional details of PCB embodiment 840, including registration void or cutout 847, which may be included to correctly register the position of the PCB 840 within housing embodiment 820 as shown in FIG. 8 A. One or more screws 821 may be used to attach PCB 840 to housing 820 as shown in FIG. 8A.

[0088] FIG. 9A and FIG. 9B illustrate an example assembly embodiment 990 which includes four modules 900A to 900D. These modules may be the similar to the modules described previously or subsequently herein. Assembly 990 is an example buried utility locator circuit board assembly, illustrating how modules such as those described herein may be used to simplify construction of the assembly, as well as to reduce size, facilitate various shapes of assemblies (in this example, a locator typically includes a round, elongate mast assembly into which assembly 990 may be positioned), standardize system components, and provide other advantages.

[0089] Some module embodiments may include heat sinks or other features to facilitate cooling of the modules, particularly when PCT circuit elements such as integrated circuits (“ICs”)S EEK 09 -452 -40 1 S PE C S C I Pe v 1 25 P C T Pa ten t A pplica tiongenerate significant hear that need to be removed from the area around the PCB or from within volumes in the electronic device in which the module is placed.

[0090] FIG. 10A and FIG. 10B illustrate one exemplary module housing configuration to enhance heat dissipation. As shown in FIG. 10B, module 1000 includes a housing embodiment 1020, a PCB embodiment 1040, with the PCB 1040 including an electrical connector 1044, and screws 1041 to attach the PCB 1040 to the housing 1020. Additional elements and features as are described elsewhere herein with respect to various module embodiments may also be include in module 1000 (not shown in FIG. 10A and FIG. 10B).

[0091] While module embodiments as described previously herein may facilitate heat dissipation with plating on housings, openings in housings, and other thermal conductive pathways, in some embodiments a module housing may include fins or other heat dissipation structures to increase the surface area of the module so as to facilitate increased heat flow to the exterior. For example, Housing embodiment 1020 of module embodiment 1000 includes multiple cooling fins 1021 to increase the heat dissipation area of the housing. In exemplary embodiments the cooling fins (or other heat dissipation structures) may be directly molded in the housings (i.e., by being part of the mold features), or in alternate embodiments may be machined or otherwise formed in the housing.

[0092] FIG. 11 illustrates details of a module embodiment 1100 including integral cooling fins shown in a cutaway view from side. Module 1100 includes a housing 1120, with the housing including a plurality of fins 1120, as well as a PCB embodiment 1140 positioned within the housing 1120. The PCB 1140 is recessed from the bottom side of the housing (shown on the lower area of FIG. 11) similar to the recessed configuration of PCB 1040 in housing 1020 of FIG. 10B.

[0093] PCB 1140 may include various electronic components such as, for example, resistor and capacitors 1143, one or more ICs, such as IC 1141A and 1141B, as well as one or more electrical connectors, such as connector 1144.

[0094] Heat dissipation is often most important from circuit elements such as ICs 1141A and 1141B, and as such it may be desirable to place these components in close proximity or in direct contact with the housing and associated cooling fins. For example, ICs 1141A and 1141B may be in direct contact with the inner side of housing 1120 as shown in FIG. 11. In someS EEK 09 -452 -40 1 S PE C S C I Pe v 1 26 P C T Pa ten t A pplica tionembodiments, heat conductive paste or other heat conductive materials, may be placed in the dashed area 1149 between IC1141A and housing 1120 to enhance thermal conductivity between the IC and the housing and associated cooling fins 1121. In some embodiments, the housing may include a thicker section or sections in the area where enhance heat dissipation is desired. One implementation of this is the thicker volume of the housing 1120 as defined between the ramped down thicker housing volume defined between the dashed lines at the ends of arrow 1153. An alternate embodiment of such a thickened contact volume and surface area is illustrated in FIG. 12F as area 1253 (in the example of FIG. 12F this area is on a heat sink, but a similar configuration may be molded into an integral heat sink housing such as shown in FIG. 10A and FIG. 11, or may be glued or otherwise formed or attached to the housing).

[0095] In some embodiments it may be desirable to control the loading between the housing and other module elements. For example, it may be desirable to limit the force between ICs 11411A and 1141B and the housing 1120. This may be implemented by, for example, using a spring, such as spring 1130, positioned between the housing and PCB, to control tightness by allowing for adjustment of torque applied to PCB mounting screws, such as screws 1121. Such a spring configuration may be similar to the configuration and functionality of a spring washer or similar element. Additional details of example spring embodiments for torque adjustment are shown in FIG. 12G and FIG. 12H and are described subsequently herein.

[0096] An alternate embodiment to the integral heat link housing embodiment shown in FIG. 10A is to include a heat sink separate from the housing itself. In this configuration the housing may have an opening on the top or upper side through which all or part of the heat sink may pass through.

[0097] For example, FIG. 12A illustrates one exemplary embodiment of this configuration in the form of electronic module embodiment 1200. Module 1200 includes a housing 1220, as well as a PCB 1240 (shown in FIG. 12C and FIG. 12E), and a heat sink 1250 (shown in FIG. 12B and FIG. 12E). The heat sink may include cooling fins or other elements to increase surface area to facilitate heat dissipation. For example, heat sink 1250 includes multiple cooling fins or stubs 1251 as shown in FIG. 12A. These fins protrude through an opening 1224 (shown in FIG. 12E)S EEK 09 -452 -40 1 S PE C S C I Pe v 1 27 P C T Pa ten t A pplica tionon the top side of housing 1220 to facilitate dissipation of heat generated in the interior volume of module 1200.

[0098] FIG. 12B illustrates module embodiment 1200 as seen from the upper or top side, showing fins 1251 protruding from the top of housing 1200. In some embodiments the fins may be positioned below the top of the housing rather than protruding from it as shown in FIG. 12B, depending on the available clearance and / or other constraints on module size or position.

[0099] FIG. 12C illustrates module embodiment 1200 as seen from the lower or bottom side, showing positioning of PCB embodiment 1240 within housing 1200, as well as multiple electrical connectors 1244 on PCB 1240. PCB 1240 may be same as or similar to PCB 840 as described previously herein and may share elements and features of the other PCBs described herein in various embodiments.[000100] FIG. 12D illustrates module embodiment 1200 from a side view, further illustrating cooling fins 1251 extending about the top side of housing 1220. Alignment pins or posts 1225 may be included in housing 1220 to facilitate mounting and alignment of the module 1200 with other assemblies or devices.[000101] It is noted that other housing and PCB embodiment element and features as described elsewhere herein, such as, for example, posts, pins, ribs, cutouts, connectors, jacks, and the like may be included in various module embodiments such as module 1200 or other module embodiments (not shown) within the spirit and scope of the disclosure.[000102] FIG. 12E illustrates various components of the module embodiment 1200 in exploded or disassembled view. These include housing embodiment 1220, which may include an open area 224 on the top or upper side to allow dissipation of heat via heat sink embodiment 1250, which may protrude through the opening as described previously herein. Module 1200 may include one or more PCBs, such as, for example, PCB 1240, which may include various electronic circuit components (not shown) as well as one or more ICs, such as ICs 1241A and 1241B as shown. Screws or other attachment mechanisms, such as screws 1221, may be used to attach the PCB to the housing.[000103] As described previously herein, it may be desirable to control the loading between the PCB and the housing or other elements, such as between the PCB and a heat sink. This mayS EEK 09 -452 -40 1 S PE C S C I Pe v 1 28 P C T Pa ten t A pplica tionbe particularly important when heat generating components such as ICs are placed against the heat sink so as to avoid crushing the ICs, damaging or destroying them. A spring mechanism such as spring embodiment 1130 as described previously with respect to FIG. 11, may similarly be used to control torque between the PCB and heat sink.[000104] FIG.12G and FIG. 12H illustrate additional details of spring embodiment 1230. The spring embodiment may comprise a spring plate or other spring mechanism. FIG. 12G illustrates spring 1230 from a side view, showing the cut and bent edge sections 1231 of the spring that provide spring action through their flexure when tightened. These springs may be made of a metal or other material that provides restorative spring action. To facilitate heat dissipation the springs may be made of a high thermal conductivity material and / or a high electrical conductivity material to provide electromagnetic shielding. In some embodiments the springs may be plated or otherwise coated with materials to enhance conductivity or mechanical properties. Other spring configurations may also be used in alternate embodiments.[000105] FIG. 12F illustrates the lower or bottom facing side of heat sink embodiment 1250. The heat sink may include a thicker area, such as area 1253, to provide thermal contact with ICs or other heat dissipation components of PCB 1140. FIG. 13 illustrates a similar thicker area of heat sink 1350 to facilitate contact with ICS or other heat generating elements or heat conductive elements (thickened area is shown between the dashed lines at either end of arrow 1353).[000106] FIG. 121 illustrates the positioning of spring embodiment 1230 and heat sink 1250 prior to placement of heat sink 1250 into housing 1220. As assembled in module 1200, the spring 1250 is between the top or upper side of heat sink 1250 and the housing 1220. Spring 1230 may be placed between PCB 1240 and heat sink 1250 and the torque may be adjusted through tightening of screws 1221 to a desired torque level. A similar configuration is illustrated in FIG. 13 and described subsequently herein.[000107] FIG. 13 illustrates a module embodiment 1300 including a housing embodiment 1320, a spring embodiment 1330, a PCB embodiment 1340, and a heat sink embodiment 1350. Module 1300 and its associated element embodiments may be similar to module 1200 and may include various elements and features as described elsewhere herein with respect to various other embodiments. Module embodiment 1300 may be similar to module embodiment 1200, with theS EEK 09 -452 -40 1 S PE C S C I Pe v 1 29 P C T Pa ten t A pplica tionadditional of a separate heat sink element rather than the integral module heat sink configuration of embodiment 1200.[000108] Housing embodiment 1300 may include an opening 1324 on the top side which may be the same as or similar to opening 1224 of housing 1220 as shown in FIG. 12E. Heat sink embodiment 1350 may include fins 1351 or other structures to increase heat dissipation surface area.[000109] PCB embodiment 1340 may include various electronic components 1343 as well as one or more ICs or other heat generating elements such as ICs 1341A and 1341B. The ICs (or other heat generating elements, not shown) may be positioned in close proximity to or in contact with heat sink embodiment 1350, such as in the thicker area between the dashed lines on FIG. 13. Thermally conductive paste or other heat conduction mechanisms may be positioned in the area 134 IB between the top of ICs 1341 and the bottom of heat sink 1350.[000110] As with module embodiment 1200, loading between the PCB and heat sink, for example, at the contact points between ICs 1341 A and 134 IB, may be adjusted by tightening screws 1321 with a torque wrench, which compresses spring 1330 between housing 1320 and heat sink 1350.[000111] The physical dimensions of module 1200, as reflected by housing 1220 and PCB 1240 dimensions and features, as well as the electrical interface of module 1200, as defined by the electronic circuit thereon and the electrical connectors 1244, may be standardized, with corresponding matching mechanical configuration and features implemented on PCB 1492 of assembly 1490. Electrical connectors 1244 mate with corresponding electrical connectors 1494 on PCB 1492 when Module 1200 is positioned as shown by arrow 1493 in area 1495 of PCB 1492. Exposed electrical traces on module 1200 and corresponding traces on PCB 1492 may mate in tight contact to provide electrical and / or thermal conductivity between PCB 1492 and module 1200.[000112] FIG. 15 illustrates details of an exploded view of another electronic module embodiment 1500 in accordance with aspects of the disclosure. Electronic module embodiment 1500 includes a housing 1520, a spring element 1530, a printed circuit board (PCB) element 1540, and a heat sink element 1550. These exemplary elements are shown for illustration purposes andS EEK 09 -452 -40 1 S PE C S C I Pe v 1 30 P C T Pa ten t A pplica tionshould not be considered limiting; various alternate embodiments of these various elements may be used in other electronic module embodiments in accordance with aspects of the disclosure. Additional details of embodiments of these elements are described subsequently herein in conjunction with FIGs. 16A-19.[000113] FIGs. 16A and 16B illustrate additional details of electronic module embodiment 1500 as assembled. As shown in FIGs. 15 and 16A & 16B, embodiment 1500 may include an electronic circuit board embodiment 1540, a heat sink embodiment 1550, an antenna module embodiment 1501 with an associated coaxial cable 1503, a housing or enclosure embodiment 1520, which may have an aperture to allow a heat sink to facilitate heat dissipation from inside the housing, and a spring embodiment such as spring plate embodiment 1530. These elements may be the same as or similar to other analogous elements disclosed previously herein.[000114] FIGs. 17A and 17B illustrate additional details of the printed circuit board (PCB) embodiment 1540 as shown in FIGs. 15 and l6A & B. FIG. 17A shows the top side of PCB 1540, which may be a system on module (“SoM”) or other electronic circuit on a circuit medium such as a PCB or other medium. FIG. 17B shows the bottom side of PCB 1540, including connectors to couple the PCB to other system components such as other PCBs or system attachment elements.[000115] The example PCB 1540 is an electronic PCB SoM module including processing functionality, storage and / or code memory, input / output (I / O) functionality, a wireless data module for sending and / or receiving data generated on the PCB or provided to the PCB, and or other electronic circuitry. Use of PCB SoM modules such as PCB 1540 allows a user to customize the module for needs based on a particular application (e.g., as a controller for various other devices, a data collection module, or various other modular functionality which require processing, memory, I / O, wireless connectivity, and / or other functions). As such, they provide a type of generic electronics including processing, memory, I / O, radio functionality, and the like for use in other devices or systems to provide this functionality without a specially designed circuit board. Various other SoMs as well as custom designed PCBs may be used in alternate embodiments consistent with the example shown in FIGs. 15 and 16A & B.[000116] The example SoM PCB 1540 is provided by Variscite, however, other manufacturers made similar modules. Alternately, as noted above, the PCB may be a customS EEK 09 -452 -40 1 S PE C S C T Re v 1 3 1 P C T Pa ten t A pplica tiondesigned PCB configured for a specific application or applications in other embodiments. Likewise, alternate housings, heat sinks, antennas, and spring element embodiments may be used in other electronic module embodiments consistent with the example shown in FIGs. 15 and 16A & B.[000117] PCB 1540 includes an RF connector 1541 for connecting a coaxial cable, such as the coaxial cable 1503 coupled to antenna 1501. A radio module 1542 on PCB 1540 may provide transceiver functionality to provide data and / or analog signaling to and / or from the electronic module.[000118] PCB 1540 can provide a highly integrated, standardized processing and mounting system on a single PCB, along with defined connections to other electronics via electrical connectors such as connectors 1544 as shown in FIG. 17B. PCB 1540 can also provide standardized holes 1547, and / or other standardized features such as described previously herein for alignment and mounting of the module to other system elements such as other PCBs or mounting elements.[000119] In various implementations, electronic module embodiments with housings and heat sinks add the ability to SoMs to electromagnetically shield the PCB, dissipate heat from components such as processors to the environment, and / or to facilitate precise alignment of connectors, such as connectors 1544, to other circuit boards or mounting mechanisms. For example, with very fine pitch pins on connectors such as connectors 1544 as shown, a slight misalignment of the board to a corresponding mounting element (e.g., a corresponding connector or pins on another circuit board) may result in damage to the connector (e.g., as shown in FIG. 17B with the damaged connections on the left side of the connector at the upper left side of the PCB).[000120] FIGs. 18A and 18B illustrate details of the embodiment 1520 of a housing or case for use in electronics module embodiments in accordance with aspects of the disclosure. Housing embodiment 1520 may comprise a plastic material in typical embodiments, however, it may also be made of metal, ceramics, or other materials, or combination thereof, in alternate embodiments.[000121] The housing may be a plated plastic, for example, such as of a carbon fiber filled ultem (polyetherimide) or other plastic material, which may be 3D printed (such as the exampleS EEK 09 -452 -40 1 S PE C S C I Pe v 1 32 P C T Pa ten t A pplica tionshown) or may be injection molded or otherwise fabricated by techniques known or developed in the art.[000122] The plastic may be plated with a metal such as nickel and / or copper to provide electromagnetic shielding and / or to aid in heat dissipation from heat generated by the PCB 1540. An aperture or opening 1524 may be formed in the housing 1520 to allow for penetration of a heat sink, such as heat sink 1550, from inside of the housing to the external environment to dissipate heat generated by components on the PCB. The heat sink and housing configuration is shown in, for example, FIG. 16B, with the top of the heat sink 1550 extended through the aperture. The housing and heat sink may be configured such that the combination of plated housing and heat shield, when assembled, provide a faraday-cage like shield over the enclosed PCB, while the aperture in the heat sink allows the coax (or other cabling, not shown) to connect signaling between the PCB and an external antenna or other external component or system.[000123] As shown in FIGs. 18A & 18B, an exemplary housing embodiment such as embodiment 1520 may have an interior facing side 1528 and an exterior facing side 1526, along with an opening for positioning a heat sink, such as heat sink embodiment 1550, partially within the housing and partially external to the housing to transfer heat generated in the interior of the housing to the external atmosphere for dissipation (i.e., air or other external gases or fluids). The exterior facing side 1526 of housing 1520 is shown with the heat sink 1550 positioned in the aperture in FIG.16B. The interior facing side of housing 1520 (not shown) is behind the PCB in FIG. 16A.[000124] FIG. 19 illustrates details of a heat sink 1550 in an exemplary embodiment. Heat sink 1550 may comprise a metal material such as aluminum, copper, or other metallic or non- metallic heat conductive materials. Heat sink 1550 may include heat dissipation features on one or more sides such as one or more exterior facing sides. For example, in an exemplary embodiment the heat dissipation features may be a pin grid to enhance cooling, including a plurality of pins 1551 to dissipate heat to the air outside of the module’s interior. The heat sink may also include a raised portion 1554 on one or more interior-facing sides to provide contact with a corresponding heat sink or integrated circuit (IC) on the PCB 1540. Other heat dissipation structures as are knownS EEK 09 -452 -40 1 S PE C S C T Re v 1 33 P C T Pa ten t A pplica tionor developed in the art, such as fins, arms, extended surfaces, and the like besides pin grids may also be used in various other embodiments.[000125] A thermal interface material (TIM), such as flexible TIM material 1543 as shown in FIG. 17, may be placed between integrated circuits (ICs) on the PCB and the heat sink or a raised section 1554 of the heat sink (if the heat sink includes one) to further aid in conducting heat from the IC to the heat sink.[000126] FIG. 20 illustrates details of a spring element, in the form of spring plate embodiment 1530 with a plurality of raised formed arms 1531. Such a spring plate may be used between the heat sink and housing to provide spring tension across a contact area to maintain a prescribed contact force. For example, the spring plate 1530 may be sized and shaped to maintain intimate contact between the thermal contact material 1543 (or other thermal contact areas or ICs on the PCB) and heat sink while limiting loading so that packaged PCB components such as ICs are not damaged (i.e., it acts as a mechanical buffer to maintain a desired contact force without creating excessive force at the PCB - heat sink contact area).[000127] Screws or other mechanical connectors (now shown in FIGs 15-20) may be used to mechanically secure the PCB and heat sink to the housing such as described previously herein in other embodiments. Screw holes and keying features may be the same as or similar to those described previously herein, for example, with respect to embodiments 100, 800, 900, 1000, 1100, 1200, and 1300. Various aspects disclosed with respect to embodiment 1500 may also be incorporated in further embodiments in conjunction with elements and features disclosed with respect to embodiments 100, 800, 900, 1000, 1100, 1200, and 1300.[000128] As described previously herein, various embodiments in accordance with aspects of the disclosure may be used to implement various electronic circuit functionality in assemblies and devices. One example of use of modules in a utility locator assembly is shown in FIG. 9A and FIG. 9B and described previously herein. FIG. 14 illustrates another assembly embodiment, wherein a module embodiment, which may be a module such as embodiment 1200 described previously herein or another module embodiment (not shown in FIG. 14) is operatively coupled to or mounted in a circuit assembly 1490. In this example circuit assembly 1490 implements a test fixture for testing module operation, however, circuit assembly 1490 may alternate be any ofS EEK 09 -452 -40 1 S PE C S C I Pe v 1 34 P C T Pa ten t A pplica tionvarious types of electronic assemblies that implement an electronic device or system or are a component of a larger electronic device or system. Other modules, such as electronic module 1500, may also be used in utility locators, utility locator transmitters, inspection camera systems, as well as in various other devices and systems.[000129] The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use various embodiments. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the disclosure.[000130] Accordingly, the presently claimed invention is not intended to be limited to the aspects shown herein, but is to be accorded the full scope consistent with the specification and drawings, wherein reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more.
