In some examples, a device can include a display coupled to a locking mechanism, wherein the locking mechanism applies a first force in a first direction, an enclosure coupled to the display with the locking mechanism, and a spring mechanism coupled to the enclosure and the locking mechanism to prevent a tension level between the display and the enclosure from exceeding a tension threshold, wherein the spring mechanism applies a second force in a second direction.

A system and method to render inoperable electronic devices disposed with a volume of a fluid-tight sealed enclosure. Thermally conductive fluids that fill one or more volumes of said sealed enclosure may be circulated away from said sealed enclosure to an external heat exchange mechanism. The volume of the sealed container contains one or more single phase or multi-phase thermally conductive fluids and may contain solid or sealed hollow structures that conform to or occupy space between said electronic devices. Pressure balancing mechanisms are included to maintain suitable pressure of gaseous fluid in a volume of the sealed container.

This is directed to an electronic device enclosure. The enclosure includes an outer periphery member forming an outer surface of a device, and to which an internal platform is connected. Electronic device components can be assembled to one or both surfaces of the internal platform. The enclosure can include front and back cover assemblies assembled to the opposite surfaces of the outer periphery member to retain electronic device components. One or both of the cover assemblies can include a window through which display circuitry can provide content to a user of the device.

A device includes a display and a housing. The housing surrounds the display and has four corners defining portions of an exterior surface of the device. The housing includes a first housing segment defining at least part of a first corner of the four corners and configured to operate as an antenna; a second housing segment defining at least part of a second corner of the four corners; and a third housing segment defining at least part of a third corner of the four corners. The third corner forms part of the housing diagonally opposite the second corner. The housing further includes a non-conductive housing component that structurally couples the first housing segment to another portion of the housing.

The disclosure relates to a function module for an electronic access control to a housing in electrical equipment. Electronic built-in modules are arranged in the housing. At least one of the built-in modules is connected to a data bus, wherein the built-in module is accessible via an interface and the data bus for the exchange of data. A switchable blocking module is provided according to the invention between the interface and the data bus, wherein the blocking module in a disable state restricts or interrupts the data traffic on the data bus at least for a data exchange between the interface and the built-in module, and in an enable state enables the data bus for an unrestricted exchange of data between the interface and the built-in module.

A system can include a key cartridge, which can include a housing, an enabling key component, and an electrical connector. The housing may be sized for placement at least partially over or around a latch release mechanism of a slidable rack sled and in a position to obstruct access to the latch release mechanism. The enabling key component can be positioned within the housing and enable operation of an electrical component situated within the slidable rack sled. The electrical connector can be coupled with the enabling key component and sized and positioned for establishing electrical connection between the enabling key component and the electrical component situated within the slidable rack sled when the pluggable key cartridge is installed relative to the server rack sled.

A monitoring and controlling apparatus includes a functional cabinet, functional units, and a control cabinet. The functional cabinet includes a plurality of frames and a door at an opening of at least a part of the frames, each frame having a predetermined accommodation size. Each functional unit is detachably accommodated in respective frame and including a circuit and a component for a function of the functional unit. The control cabinet is disposed next to the functional cabinet, and configured to monitor and control the functional units.

Embodiments of the present invention provide an improved access control unit with an asymmetric transmission pattern. A shielded backplate reduces the interior transmission pattern. The secure side transmission pattern is much smaller than the unsecure side transmission pattern, such that a credential located within the secure side area of a building is not likely to trigger the access control unit, thus reducing the risk of an unauthorized access.

An anti-tamper mechanism to disable an electronic device during unauthorized physical access includes: a turnover assembly, spring, turnover member, conducting members, and a latch. The turnover body defines a plurality of receiving grooves. Several conducting members are received in the plurality of receiving spaces in a certain and predefined order to enable electrical coupling with the circuit board. The latch includes a supporting bracket, a guiding rod slidably positioned on the supporting bracket, and a latching member positioned on the guiding rod. The latching member engages with the turnover body to hold the turnover member in check, but when the latching member disengages from the turnover body in disassembly, the turnover member displaces the conducting members thereby destroying the certain and predefined order and electrical decouples the circuit board to disable the electronic device.

A potted electronic device comprises an electronic device at least partially encapsulated by an energetic potting material. The energetic potting material comprises a halogenated urethane binder and a metal fuel dispersed within the halogenated urethane binder. Related energetic potting materials and methods of forming electronic devices at least partially encapsulated with the energetic potting materials are also disclosed.
