  • Patent number: 11044819
    Abstract: A multilayer printed circuit board (PCB) includes a laminate between a first core and a second core. The first core is located in a middle position of the multi-layer PCB and includes a resistive heating element directly upon a first core substrate. A portion of the resistive heating element protrudes from the multi-layer PCB perimeter. A laminator that fabricates the PCB includes a platen, a power supply, a processor, and memory that has program instructions embodied therewith which are readable by the processor to cause the laminator to position the platen against a surface of the multi-layer PCB and cure the laminate by heating the multi-layer PCB with the platen and cure the laminate by heating the multi-layer PCB with the resistive heating element.

  • Publication number: 20210165884
    Abstract: A system and method for providing a secure image load. The system includes a microcontroller. The microcontroller has a plurality of physically modifiable internal components (PMIC). Each of the plurality of PMICs can only be modified one time. The system further includes an image loader configured to load a boot image from the memory of the microcontroller, and a checksum calculator configured to calculate a checksum value for the boot image. The system further includes a checksum burner configured to modify the plurality of PMICs to create a binary representation of the checksum value for the image. A checksum value is calculated for the image. This checksum value is written to the microcontroller. The value is burned into the microcontroller using the PMICs. Further, responses to the checksum mismatch are burned into the microcontroller using the PMICs that are present in the microcontroller.

  • Publication number: 20210168455
    Abstract: A system and method for providing content to a user outside of a home region. A portable device displays content to a user through a network connection. A home content provider provides content to the portable device from the home region. Some of the content provided is region restricted content. A location verifier determines that the portable device and the user are both physically located within the home region. The location verifier issues to the user a location token when the user and the portable device are in the home region. A token verifier verifies the location token when the user requests the region restricted content outside of the home region. The token verifier further instructs the home content provider to provide region restricted content to the user when the user has the location token.

  • Patent number: 11016255
    Abstract: A method of forming a coaxial wire that includes providing a sacrificial trace structure using an additive forming method, the sacrificial trace structure having a geometry for the coaxial wire, and forming a continuous seed metal layer on the sacrificial trace structure. The sacrificial trace structure may be removed and a first interconnect metal layer may be formed on the continuous seed layer. An electrically insulative layer may then be formed on the first interconnect metal layer, and a second interconnect metal layer is formed on the electrically insulative layer. Thereafter, a dielectric material is formed on the second interconnect metal layer to encapsulate a majority of an assembly of the first interconnect metal layer, electrically insulative layer and second interconnect metal layer that provides said coaxial wire. Ends of the coaxial wire may be exposed through opposing surfaces of the dielectric material to provide that the coaxial wire extends through that dielectric material.

  • Patent number: 10957623
    Abstract: Forming a thermal interface material structure includes forming an assembly that includes a thermal interface material disposed between a first mating surface and a second mating surface. The first mating surface is associated with a module lid, and the second mating surface is associated with a heat sink. Protruding surface features are incorporated onto the first mating surface or the second mating surface. The process also includes compressing the assembly to form a thermal interface material structure. The thermal interface material structure includes the thermal interface material disposed within an interface defined by the first mating surface and the second mating surface. The protruding surface features protrude from the first mating surface or the second mating surface into selected areas of the interface to limit relative movement of the mating surfaces into the selected areas during thermal cycling to reduce thermal interface material migration out of the interface.

    Abstract: A lock system and method for alerting a user or other entity that a lock has been or is being tampered with is disclosed. The lock includes at least one enhanced security pin that is electrically isolated from the rest of the lock. When the lock picker attempts to pick the lock a portion of the enhanced security pin contacts either the plug or the outer casing of the lock to complete a circuit with an alert component. The completion of the circuit causes the alert component to generate an alert signal that can be observed by the user or other entity.
