Description

EVIDENCE PRESERVATION CONTAINER WITH ELECTRICAL INTERFACERELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 656,073 filed June 4, 2024, and U.S. Provisional Patent Application No. 63 / 753,368 filed February 3, 2025. The contents of the above-identified applications are incorporated by this reference in their entireties for all purposes as if fully set forth herein.TECHNICAL FIELD

[0002] The present disclosure relates generally to the field of evidence preservation. More particularly, the present disclosure relates to bags, pouches and other enclosures for preserving digital and other physical evidence throughout the chain of custody.BACKGROUND

[0003] In digital forensics, maintaining power to digital evidence while in transport or storage, such as with seized cell phones, is imperative. Mobile devices must remain charged to ultimately allow for proper password cracking and data extraction when under forensic analysis. Traditionally, the preservation of digital evidence in this manner has required the use of radio frequency (RF) shielding bags, charging cables, batteries, all connected to the digital device. With these connections in place, the device is exposed to these objects, remaining physically unseparated.

[0004] One problem with this traditional method of transporting and storing digital evidence is that other types of evidence that might be important to the forensic analysis process, such as blood, hair follicles, semen and fingerprints, cannot be preserved properly. These types of physical evidence often essentially become sacrificed in order to preserve the digital evidence. These types of physical evidence may be excluded from being used as criminal evidence due to improper preservation and handling. They may also contaminate other nearby objects that maybe used with other digital devices in subsequent evidence handling operations.

[0005] A solution is needed that allows for proper preservation and handling (e.g., chain of custody) of digital evidence as well as physical forensics evidence. This solution should preferably allow mobile devices to remain charged and RF shielded, while properly preserving physical evidence such as blood, hair follicles, semen, and fingerprint at the same time.BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Referring now to the drawings, like reference numerals designate identical or corresponding features throughout the several views.

[0039] Features of particular preferred embodiments of an evidence preservation container with electrical charge interface in accordance with the present disclosure are disclosed herein. However, alternate embodiments of the evidence preservation container may be constructed with fewer or more features and components than those shown and described in connection with the illustrated embodiments.

[0040] Example embodiments of an evidence preservation container in accordance with the present disclosure are shown generally at 100. Referring to FIGS. 1 and 5, an evidence preservation container 100 for sealing an article of evidence 200 from an ambient environment 106 may comprise an outer perimeter 104, an evidence compartment 102 defined within the outer perimeter 104, and an interface sleeve 128. An electrical interface element 108 may extendthrough the interface sleeve 128 in electrically conductive communication between the evidence compartment 102 and the ambient environment 106. One or more interface seal elements 154 may sealingly secure the interface sleeve 128 around the electrical interface element 108. This may involve, for example, securely circumferentially wrapping the interface sleeve 128 around at least a portion of the electrical interface element 108.

[0041] Referring to FIGS. 20 and 26, in particular implementations of the evidence preservation container 100, an interface seal element 154 may comprise a heat-induced bond between the sleeve portion 130 of the first panel 110, the sleeve portion 132 of the second panel 112, and the interface cable 168. As a result, the cable itself may be fully heat-sealed into the bag’s interface sleeve 128. In certain implementations of this approach, this is facilitated by the cable exterior being made from TPE (thermoplastic elastomer), which allows it to bond directly to the PA / PE (polyamide / polyethylene) material of the bag when heat sealed. In particular such implementations, the heat seal fully encloses the cable within the bag’s material, ensuring a completely integrated, airtight, and tamper-evident seal without requiring additional fasteners. This method of manufacturing the evidence preservation contain 100 may improve durability, enhance evidence integrity, and eliminate potential gaps or weaknesses that could exist with other fastening techniques. FIGS. 17 through 25 illustrate one example set of steps which may be used in the method of manufacturing an evidence preservation container 100 in the interface seal element 154 comprises a heat-induced bond between the sleeve portion 130 of the first panel 110, the sleeve portion 132 of the second panel 112, and the interface cable 168.

[0042] Referring to FIGS. 2 and 6, particular implementations of the evidence presentation container 100, may comprise a first panel 110 and a second panel 112 disposed oppositely of one another. In such implementations, the evidence compartment 102 may be defined between the first panel 110 and the second panel 112. Referring to FIG. 12, the interface sleeve 128 may be comprised of a sleeve portion 130 of the first panel 110 and a sleeve portion 132 of the second panel 112.

[0043] Referring to FIGS. 1 and 13, in certain implementations of the evidence presentation container 100, the interface sleeve 128 may include a sleeve inner end 134 and asleeve outer end 136. The sleeve inner end 134 may be disposed inboard of the outer perimeter 104. Moreover, the sleeve outer end 136 may also be disposed inboard of the outer perimeter 104.

[0044] Referring to FIG. 1, the outer perimeter 104 may include a first lateral edge 124 and a second lateral edge 126 disposed oppositely of one another. The outer perimeter 104 may also include a base edge 120 extending between the first lateral edge 124 and the second lateral edge 126. An insert portion 114 may be defined, for example, oppositely of the base edge 120. Referring to FIGS. 2 and 6, the base edge 120 may be, for example, a fold line between the first panel 110 and the second panel 112.

[0045] Referring to FIGS. 2-4, the insert portion 114 may be movable from an open configuration (see, e.g., FIGS. 1 and 2) to a closed configuration (see, e.g., FIGS. 4 and 5). When the insert portion 114 is in the open configuration, the evidence compartment 102 may be accessible from the ambient environment 106 to enable an article of evidence 200 to be placed within the evidence compartment 102 from the ambient environment 106. In contrast, when the insert portion 114 is in the closed configuration, access to the evidence compartment 102 by way of the insert portion is prevented. For example, the insert portion 114 may include a seal flap 116 and an adhesive layer 118 (or the like), and may include tamper-resistance features which would make any effort to move the insert portion 114 from the closed confirmation to an open confirmation readily visually apparent.

[0046] Referring to FIG. 1, in particular preferred implementations of an evidence preservation container 100 the first panel 110 and the second panel 112 may be joined together at least in part by way of a first lateral edge seal 140 adjacent to the first lateral edge 124, and a second lateral edge seal 142 adjacent to the second lateral edge 126. Moreover, the first panel 110 and the second panel 112 may also be joined together at least in part by way of a pair of inboard slot seals 150 and a pair of outboard slot seals 152. A pair of sleeve slots 146 may be disposed on opposing sides of the interface sleeve 128. Each of the sleeve slots 146 may be defined by a respective one of the inboard slot seals 150 and a respective one of the outboard slot seals 152.

[0047] Referring to FIGS. 1 and 13, each outboard slot seal 152 may preferably extend from the first lateral seal 140 to a respective one of the inboard slot seals 150. Correspondingly, each inboard slot seal 150 may extend from the sleeve outer end 136 to a respective one of the outboard slot seals 152.

[0048] Depending upon the particular implementation of the evidence presentation container 100, the interface seal element 154 may comprise one or more zip ties, clips, clamps, shrink tubing, sealing bands, adhesive seals, some combination thereof or the like. For example, in the implementation illustrated in FIGS. 1 and 15, the interface seal element 154 comprises a plurality of zip ties.

[0049] Referring to FIG. 5, depending upon the particular implementation of the evidence preservation container 100, the electrical interface element 108 may comprise an inner connector 156, an outer connector 158 and an interface cable 168 extending therebetween. The inner connector 156 may be disposed within the evidence compartment 102 and configured to be selectively electrically connected to the article of evidence 200, whereas the outer connector 158 may be disposed outward of the sleeve outer end 136 and configured to be selectively connected to a source of power 208.

[0050] Referring to FIG. 1, in particular preferred implementations of the evidence preservation container 100, a printed cut line 160 may be disposed adjacent the base edge 160.

[0051] The first lateral edge seal 140, the second lateral edge seal 142, the inboard slot seals 150 and the outboard slot seals 152 may be in the form of heat-induced bonds between the first panel 110 and the second panel 112. Additionally, or in the alternative, one or more of these seals may be in the form of chemical adhesive bonds between the first panel 110 and the second panel 112, or fold lines. For example, a base seal 138 may be provided along the base edge 120 by way of, for example, a fold line between the first panel 110 and the second panel 112, a heat seal, an adhesive seal, some combination thereof, or the like.

[0052] Referring to FIGS. 1 and 13, in certain preferred implementations of the evidencepreservation container 100, the outboard slot seals 152 may be disposed at least a sleeve offset distance 170 away from the base edge 120. The sleeve offset distance 170 may preferably be, for example, from 0.5 and 2 cm, from 0.5 and 3 cm, or from 1-4 cm. However, other distances are possible and may be preferred in certain implementations.

[0053] In particular preferred implementations of the evidence preservation container 100, the first panel 110 and the second panel 112 may be comprised of a polymer sheet. The polymer sheet may be, for example, PET or PE. The polymer sheet may preferably be sufficiently transparent to allow the nature and details of an article of evidence 200 sealingly disposed within the evidence compartment 102 to be visually discernible by the naked human eye from a position external of the container 100.

[0054] One objective of exemplary implementations of the evidence preservation container 100 disclosed herein, which may otherwise be referred to as a Charge Preserve Evidence Bag, is to improve the ability to preserve evidence by introducing an adaptive hermetic, or near-hermetic, sealing sleeve. This feature allows for electronic devices stored within the bag to be connected to a protruding cable and charged without compromising evidence integrity, contamination, or tampering, offering a versatile solution that supports various sealing methods, materials, and connection mechanisms. The objective is to ensure device charging while maintaining a controlled internal environment, thus preserving the critical integrity of the evidence within.

[0055] Certain preferred implementations of the evidence preservation container include a versatile "tail-like sleeve" or opening, which enables the insertion and connection of a cable (for example, a charging cable or USB cable tip) to devices inside the bag. This sleeve may be adapted to accommodate various sealing technologies, materials, and cable connection methods, offering a solution that allows for device charging inside of the bag along with physical evidence preservation.

[0056] Innovative Construction Techniques:

[0057] Key aspects of preferred implementations of the evidence preservation container include adaptable sealing mechanisms incorporated around a tail-like sleeve section for cable insertion, which are not necessarily limited to traditional heat seals. Mechanisms such as mechanical seals, magnetic seals, or other technologies may ensure a durable and reliable hermetic, or possibly non-hermetic but tight seal around the cable. The design's flexibility extends to the materials used, allowing for the incorporation of various polymers, fabrics, or composites. Furthermore, connection mechanisms like zip ties, clips, clamps, shrink tubing, sealing bands, or adhesive seals can be utilized, ensuring the sleeve securely attaches to the charging cable while maintaining the integrity of the seal.

[0058] Evidence Bag:

[0059] In the preferred embodiment, the evidence bag itself may be made of plastic materials such as polyethylene terephthalate (PET) and polyethylene (PE), which may offer excellent durability, chemical resistance, and barrier properties essential for preserving evidence integrity. In alternate embodiments, the material may vary, including options like paper, cardboard, metal, or other types of plastics.

[0060] In alternate embodiments the bag may not be a bag at all but may instead be a box, a tube, or any other type of structure.

[0061] In the preferred embodiments the evidence bag may include features such as a tamper-proof seal on the top of the bag. It may also include a cut line at the bottom of the bag to allow for opening the evidence bag for various stages of analysis. This cut line may be resealable with tape to allow the evidence to maintain proper chain of custody.

[0062] In alternate embodiments no tamper proof seal may exist, a non-tamper proof seal may exist, or another method of closing and opening the bag may exist. There may be no bottom cut line or there might be multiple cut lines, or cut lines may exist on the side or other areas of the bag.

[0063] Connection Mechanism:

[0064] In the preferred embodiment, the sleeve's connection mechanism to the protruding cable may be by use of zip ties mechanically securing the sleeve to the cable. There may be a series of zip ties, such as 3, to provide redundancy. The charge cable may be made of flexible plastic or rubber so as to offer as tight of a seal as possible, reducing or eliminating the transfer of substances from inside to outside of the evidence bag, or from outside to inside.

[0065] In alternate embodiments, the sleeve's connection mechanism to the cable may be limited to a single type of sealing mechanism, or multiple types in any combination of number or type. The types of connection or sealing methods may include adhesives, metal rings metal clamps, plastic rings, plastic clamps, any type of material of ring or clamp, any type of material that provides a compression connection, other non-compression connections such as adhesives, heat sealing, or other.

[0066] In the preferred embodiments the charge cable may be installed by the manufacturer before delivery to customer. It may be a single continuous cable protruding from inside to outside of the bag, with connectors on either side. It may be made of rubber or plastic sleeve material to provide a tight connection with the bag.

[0067] In alternate embodiments the charge cable may not be a single continuous cable at all, but may instead be a combination of multiple cables such as one cable on the outside, one on the inside, and a connector in between. A connector in between may be the part of the bag that allows for power I / o with separate cables or connectors inside and outside to allow for flexibility of connection type. Or there may be no cable at all, but instead an area of the bag that allows for power I / o such as a capacitive charging pad. In alternate embodiments the charge method may not be installed by the manufacturer but may instead be installed by the customer or modified by the customer. The cable sleeve may not be made of plastic or rubber but may instead be made of fabric, nylon or other material. The cable may not be a common charge cable but may instead be modified to reduce the passage or physical material.

[0068] Conclusion:

[0069] Embodiments of the presently disclosed evidence preservation container represent a pivotal advancement in the field of evidence preservation. Its innovative design provides a flexible and secure method for charging electronic devices within an evidence bag, while complying with common forensic standards for hermetically sealed and tamper-evident evidence bags, addressing a critical gap in current practices. Through its adaptability to various sealing methods, materials, and connection mechanisms, this invention offers broad applicability and the capacity to evolve with future needs and technologies in digital forensics, setting a new standard in evidence preservation.

[0071] What follows is additional non-limiting information which may pertain to certain implementations of the evidence presentation container 100 and methods of manufacturing same.

[0072] Background and Need for Innovation:

[0073] In modern law enforcement and digital forensics, the secure handling and preservation of evidence, including electronic devices and their accessories, may be critical. Current evidence bags often lack the versatility, technological advancements, and durability required to address challenges such as technology power issues, contamination, environmental exposure, and tamper-evident sealing. These limitations may hinder effective evidence handling, particularly in scenarios where the integrity of forensic materials is paramount.

[0074] Existing designs may not accommodate both electronic devices and their peripherals, such as phone cables, power, and data cables, in a manner that ensures reliable containment and preservation. Products may offer simple sealing mechanisms, or charging possibilities that could fail under certain conditions, potentially exposing evidence to contaminants. Furthermore, these designs may not provide adequate adaptability, and storage safety, data safety, and documentation for varying device and cable configurations, limiting their usability in diverse forensic scenarios.

[0075] The increasing reliance on digital evidence in legal cases underscores the urgent need for a more advanced solution. What is needed is an evidence bag that not only securelycontains electronic devices alongside their accessories, but also ensures hermetic sealing, power continuity, and data security while under use. Such a design must also be adaptable to various configurations, offering law enforcement and forensic professionals a reliable, durable, and versatile tool for preserving evidence against tampering, contamination, and environmental degradation. By addressing these gaps, the proposed solution aligns with the growing technological and operational demands of modern forensic investigations.

[0076] Objective of the Innovative Design:

[0077] One primary objective of the proposed evidence bag may be to provide advanced sealing techniques and durable materials, potentially allowing for secure containment of electronic devices and their accessories. The design may address key challenges such as ensuring a consistent, durable, and hermetic seal around phone cables and other components, preserving power, data, and the integrity of evidence while being versatile enough to meet the needs of various forensic applications. Its features may be designed to simplify forensic workflows, reduce the likelihood of user error, and support compliance with evidence preservation standards.

[0078] This evidence bag may serve as a versatile, durable, and user-friendly tool for law enforcement and forensic professionals. Offering features that preserve the integrity of digital evidence under challenging conditions, it may represent an advancement in the secure handling and preservation of forensic materials.

[0079] Elements of Certain Embodiments:Certain preferred embodiments of the evidence preservation container 100 may include one or more of the following features and advantages:(a) Cylindrical Channel for Cable Accommodation: to provide a precise fit for phone cables, data cables, and similar accessories;(b) Hermetic-Sealing Mechanism: To ensure a watertight and airtight closure;(c) Puncture-Resistant Materials: Designed to withstand environmental stressors and prevent damage to the bag or contamination of its contents;(d) Configuration to Satisfy Data and Power Needs: Special consideration for cabling mechanisms that work congruently with forensics data recovery, power maintenance, and data privacy standards;(e) Adaptable Design: May accommodate various device and cable configurations;(f) Sealing of Digital and Electronic Products: May Secure electronics preventing contamination of sensitive materials;(g) Designed to work cohesively with Law Enforcement and Forensics Standards.

[0080] Description of Certain Preferred Implementations of the Evidence Preservation Container:

[0081] Cylindrical Channel for Cable Accommodation: Preferred Embodiments

[0082] In certain preferred embodiments, the bag may include a molded cylindrical channel designed to accommodate phone cables, data cables, and other apparatuses needed to securely keep electronic and digital assets. See, e.g., FIGS. 18-25. This channel may ensure proper alignment during the sealing process, potentially preventing uneven closures and improving reliability. This may be seen in the resulting hermetic ceiling and hermetically secured devices and materials. This may also include the sealing of materials needed for law enforcement and forensics uses.

[0083] Cylindrical Channel for Cable Accommodation: Alternative Embodiments

[0084] In alternative embodiments, the evidence bag may not include a cylindrical channel but instead may utilize other structural features to accommodate phone cables, data cables, and similar apparatuses. For example, it may feature a rectangular or elliptical channel, pockets, flexible flaps, or adhesive-lined openings that could adapt to cables of varying sizes and shapes. These alternative configurations may provide comparable levels of containment and sealing, using materials such as flexible polymers, thermoplastics, or any other sealable material. The sealable materials may be reinforced by metal, carbon fiber, or other structural materials or composites to ensure durability and versatility. Additionally, the channel or equivalent featuremay not be molded directly into the bag but instead be a detachable component, allowing for interchangeability and customization based on specific forensic requirements. Further, the alternative embodiments may allow for the channel’s location and orientation to vary. Instead of being centrally positioned, the feature may be located on the edges, corners, or any other location on the bag. There may be more than one channel and may appear on multiple different locations on the bag. The sealing mechanism may incorporate a vacuum seal, glue or adhesive, magnetic closures, zip-lock fasteners, zip ties, heat sealing, or any other sealing method to achieve a durable, hermetic, and tamper-resistant seal. The sealing mechanism may incorporate a combination of multiple sealing methods to ensure a hermetic and tamper-resistant seal. These embodiments could also include integrated connectors or couplings such as universal phone cables or USB adaptors to facilitate power and data transfer while maintaining secure containment, addressing the diverse operational needs of law enforcement and forensic professionals.
