The following detailed description proposes exemplary specific embodiments of equipment, methods and systems related to attachments for devices. For example, for convenience, features such as structure, function, and/or characteristic are described with reference to a specific embodiment; various specific embodiments can be implemented with one or more of any suitable features.

In order to illustrate some exemplary techniques for physical access protection of the device 100, it is important to understand the basic information about the device 102. The following basic information can be regarded as a basis for properly explaining the content of this disclosure.

Controlled RFID devices used to track vehicles in toll road systems and controlled traffic areas need tamper detection and protection features. In addition, the RFID device should provide protection from dust and/or water ingress. In addition, the enclosure often requires some protection and identification of when access to the device has occurred or may have occurred. There is an urgent need to provide a system and method for physical entry protection of devices.

The device 102 as summarized in FIGS. 1A and 1B can solve these problems (and others). The device 102 can be configured to allow for electronic tampering/intrusion detection of a housing component (eg, tamper-proof tag 106) of the device 102 separately mounted to a shared surface (eg, surface 104) through separation. The mounting surface and the intermediate mounting medium can help prevent or limit the entry of substances into the device 102. In one embodiment, the device 102 can provide visible evidence of tamper detection through a transparent mounting surface.

In one embodiment, the device 102 may be configured to include a strategically segmented housing component combined with a special form and formula of PSA (pressure sensitive adhesive). The combination of enclosure partitioning and PSA attributes makes tamper detection and protection or restriction of dust and water entry possible at a lower economic cost than current conventional alternatives.

In one embodiment, the tamper-proof tag 106 is a small “tag” of the housing material placed in the through hole of the device 102. The tamper resistant tag 106 may be a physically separate component that is coupled to a conductive element that makes two pads on the circuit board in the device 106 contact.

A pressure sensitive adhesive (PSA) (for example, double-sided tape) can be used to fix or couple the device and tamper-resistant label 106 to the surface 104. In one embodiment, the PSA material can be die cut into two separate regions. The first area is the main bonding interface for attaching the shell body to a surface, such as a wall or windshield. Inside this interface is an anti-tamper tag 106. The first area of the PSA includes a hole whose size is made such that the tamper-proof label 106 will not contact the first area of the PSA. The size and position of the second area of the PSA material are made to be attached only to the mounting surface of the tamper-proof label 106. Therefore, the two areas of PSA are separated from each other and secure Different components that fit into the housing.

If an attempt is made to remove the device 102 from the surface 104, there is no way to directly access the tamper-resistant label 106 without damaging the surface, the device, or the interface PSA that secures the device 102 to the surface 104. Generally, the device 102 will be pulled away from the surface 104, and the separately installed tamper-resistant tag 106 will still be attached to the surface 104. This event caused damage to the tamper contact of the circuit board soldering pad, and the tamper event can be electronically recorded.

Ingress protection is important to the protection of the device because it ensures proper operation and prevents difficult-to-verify tampering methods that involve the device being contaminated by dust or fluids. The device 102 can be assembled so that all seams of the device 102 are within the interface of the mounting surface (e.g., surface 104). In one embodiment, the interface between the device 102 and the surface 104 is completely covered and includes a non-porous primary adhesive layer, a closed-cell foam central layer (if applicable), a non-porous secondary adhesive layer, and a secondary adhesive layer for use before installation. PSA with non-porous lining for storage. The non-porous main adhesive layer of PSA conformally covers the main joint between the main housing and the mounting plate to provide a reliable entry barrier. Without this method, the seam needs to be sealed by other methods, such as gaskets, glue or ultrasonic welding, except that PSA requires attachment devices. These alternative methods are much more expensive and less reliable than PSA, such as the aforementioned PSA. In an embodiment, in addition to the method of sealing them, the PSA needs to attach these devices, so the present invention eliminates the need for these sealing operations through the strategic use of the PSA. This is cost-effective.

The second entry is the seam between the tamper-proof label 106 and the mounting plate on the device 102. According to the function, it must be glued to the mounting plate of the main body of the device 102. Since the tamper-proof tag 106 must be easily detachable from the device 102, Seams are inevitable and the above-mentioned conventional alternative sealing methods are even less applicable. The two main situations where tampering of the seam must be prevented are during shipping/storage or pre-installation and when installing the device 102 on the surface 104. Before installation, the non-porous lining covers the gaps and seams between the tamper-proof label 106 and the mounting plate of the device 102. Therefore, it can be prevented from entering during shipment and pre-installation storage. After installation, the function of the lining is replaced by the surface 104, which once again provides the non-porous interface of the PSA and prevents entry.

In another embodiment, a security film can be used on the PSA substrate, and the device 102 can be fixed to a transparent surface 104, such as a window or a windshield. The protective film or tape may include a single-sided printing tape coated with a maintenance/access interface with extremely low tear strength during manufacture. The printing of such tapes is usually proprietary, which contains holograms or other graphical indicators that are difficult to replicate. The tape breaks when unnecessary access occurs and the interruption can be detected by visual inspection of the transparent surface. Through the transparent surface itself, the observer can see the surface of the mounting tape facing the transparent surface. The use of a printed protective film in the mounting adhesive layer facing the transparent surface allows visible evidence of removal to be observed, even if the device is reinstalled on the transparent surface. There are many advantages, including the cost-effectiveness of combining PSA features and protection (no separate cost component), and the ability to check for tampering without removing the device 102, or in the case of transportation applications, without entering the vehicle.

Turning to FIGS. 2A and 2B, the simplified expanded orthographic view of FIGS. 2A and 2B illustrates a specific embodiment of the device 102. During transportation and before the device 102 is fixed to the surface 104, the device 102 may include an anti-tamper tag 106, a main body 108, a mounting plate 110, a mounting plate PSA 112, a removable liner 114, And anti-tampering label PSA 116. The tamper-proof label PSA 116 can be the same or different from the PSA 112 of the mounting plate. The anti-tamper tag 106 can be gently retained in the pocket of the mounting plate 110 by a force retention method, such as a sliding fit.

Turning to FIG. 3, the simplified orthographic view of FIG. 3 illustrates a specific embodiment of a part of the device 102. The device 102 may include an anti-tamper tag 106, a main body 108, a mounting plate 110, a mounting plate PSA 112, and an anti-tamper tag PSA 120. The anti-tampering label PSA 120 may be the same or different from the anti-tampering label PSA 116. The anti-tamper tag 106 can be pressed against the surface 104 by the compression mechanism 118. The compression mechanism 118 provides an outward force on the tamper-proof tag 106 from the tag to the tampering contact pad on the internal circuit board (for example, a printed circuit board).

Turning to FIG. 4, the simplified orthographic view of FIG. 4 illustrates a specific embodiment of a part of the device 102. The device 102 may include an anti-tamper tag 106, a main body 108, a mounting plate 110, a mounting plate PSA 112, and an anti-tamper tag PSA 120. The anti-tampering label PSA 120 may be the same or different from the anti-tampering label PSA 116. The tamper-proof tag 106 can be fixed in position by a retaining mechanism, such as a snap button. If the tamper resistant tag 106 is fully retained in the device 102, no compression force is transferred to the surface 104 through the compression mechanism until the tamper resistant tag 106 and the device 106 are separated by the compression mechanism 118. The compression mechanism 118 provides an outward force on the anti-tamper tag 106. For example, a snap button or some kind of fixing member can be used to assist the tamper-proof tag 118 in the device and to resist the outward force from the compression mechanism 118.

Turning to FIG. 5, the simplified orthographic view of FIG. 5 illustrates a specific embodiment of a part of the serviceable chassis 100. As shown in Figure 5, the tamper-proof label 106 can be It is coupled and contacted with the anti-tampering label PSA 120 and the compression mechanism 118. The compression mechanism 118 may be beryllium copper or electroplated brass forming a spring contact. The forward compression of the compression mechanism 118 can maintain continuity before, during, and after installation.

Turning to FIG. 6, the simplified orthographic view of FIG. 6 illustrates a specific embodiment of the device 100. The device 102 can be assembled so that all seams of the device 102 are within the interface of the mounting surface (e.g., surface 104). The interface between the device 102 and the surface 104 can be completely covered, including a non-porous primary adhesive layer, a closed cell foam central layer (if applicable), a non-porous secondary adhesive layer, and a non-porous lining for storage and installation attached to the secondary adhesive layer The mounting plate PSA 112. The non-porous main adhesive layer of the PSA conformally covers the main joint between the main housing and the mounting plate to provide a reliable entry barrier.

Turning to FIG. 7A, the simplified orthographic view of FIG. 7A illustrates a specific embodiment of the device 102 fixed to a transparent or semi-transparent surface 122. The transparent or translucent surface 122 may be a window, windshield, frosted glass, or some other type of transparent or translucent material. The device 102 can be fixed to the transparent or translucent surface 122 with a protective film 124. The protective film 124 may include a single-sided printing tape coated with the mounting board PSA 112 to have extremely low tear strength. The printing of this type of tape is usually exclusive, which contains holograms or other difficult-to-replicate graphical indicators.

Turning to FIG. 7B, the simplified orthographic view of FIG. 7B illustrates a specific embodiment of the device 102 fixed to the transparent or semi-transparent surface 122. As shown in FIG. 7B, the device 102 has been detached from the transparent or translucent surface 122. As a result, the protective film 124 has been damaged.
